Answer:

B. Being able to plan in advance for a genetic disorder in a child.

Being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).

A genetic disorder is a type of disease caused in whole or in part by a change in a DNA sequence away from the normal sequence.

It can be caused by several reasons like

1. Monogenic Disorder

It is caused by a mutation in one gene

2. Multifactorial Inheritance Disorder

It is caused by mutations in multiple genes

3. Combination of gene mutations and environmental factors.

4. Damage to chromosomes by the changes in the number or structure of entire chromosomes, the structures that carry genes.

Genetic counseling helps parents for better understand test results and treatment options, helps deal with emotional concerns, and provides referrals to other healthcare providers and advocacy and support groups.

Thus, being able to plan in advance for a genetic disorder in a child is an advantage for a parent who sees a genetic counselor. So, the correct option is (B).

Answer: Resistance exercise

Explanation:

A decrease in the quantity of mineral in the bone can occur due to inactivity or less body movements which may be as a result of old age or a disease condition.

RESISTANCE EXERCISE is a type of training in which the muscles are subjected to work against a weight to help increase the strength of the muscles. Below are the different forms of resistance exercise:

--> Resistance bands: these bands provides resistance when they are stretched.

--> Suspension equipment: this training tool uses the body weight and gravity to form resistance.

--> Your own body weight: one can conveniently use the body weight for push ups and squats.

Generally, the resistance exercise helps to reverse the loss of bone mineral density through increasing muscle strength and tone and reducing inactivity in the muscles that led to diminished bone mineral density.

Answer: A reading frame shift mutation involves the insertion or deletion of a certain number of nucleotides that is not divisible by three, because the cell reads a gene in groups of three bases (a codon). This type of mutation can change the reading frame causing a different translation from the original, because it will code for different amino acids.

Explanation:

DNA is the double-stranded molecule composed of nucleotides which are the functional unit of nucleic acids and are composed of a base (which can be Adenine, Thymine, Guanine, Cytosine, and Uracil replacing Thymine in RNA), a phosphate group and a sugar which can be ribose in RNA and deoxyribose in DNA. The reading frame is one of the possible ways in which a sequence of DNA or RNA nucleotides can be divided to form a group of codons that are consecutive and non-overlapping. A codon consists of a set of three nucleotides and each codon codes for an amino acid during translation or protein synthesis. When DNA is transcribed into messenger RNA (mRNA), this mRNA is read on ribosomes during translation and the three bases of each codon will code for an amino acid.

A single-stranded nucleic acid (RNA) molecule has a phosphate end, called the 5' end (read five prime end) and a hydroxyl end, called the 3' end. These ends define the 5'-3' direction. There are three possible reading frames in which a nucleotide sequence can be read in the 5'-3' direction. Each of these reading frames could start at a different nucleotide of the same codon. In a double-stranded nucleic acid (DNA), there are also three additional reading frames corresponding to the complementary strand, but in an antiparallel direction. Since the two strands of a double-stranded nucleic acid are antiparallel, the 5'-3' direction of the second strand corresponds to the 3'-5' direction of the first strand.

Generally, there is at most, a single biologically relevant reading frame for a given section of a nucleic acid, and that reading begins when a start codon indicating the initiation of protein synthesis is found in the messenger RNA. And the process stops when a stop codon is reached.

An insertion is a type of mutation that involves the addition of genetic material. It can be small and involve a single DNA base pair, or large and involve a fragment of a chromosome. A deletion is a type of genetic mutation in which genetic material is lost, from a single DNA nucleotide pair to an entire chromosome fragment. A reading frame shift mutation involves the insertion or deletion of a certain number of nucleotides that is not divisible by three, because the cell reads a gene in groups of three bases, as it was explained before. This type of mutation can change the reading frame causing a different translation from the original.

meiosis

Explanation:

meiosis occurs first in the sex gametes while mitosis occurs later in growing cell

Answer:

The correct answer is - Ploidy is the number of sets of chromosomes in a biological cell.

Explanation:

Ploidy is the number of sets of the chromosome in a living cell. Ploidy is known for different condition such as haploid, diploid, and aneuploid, and many more depends how many homologues chromosome numbers are present in the cell.

Diploid cells are common in many organisms where one chromosome come from the mother gamete and the other from the father gamete and makes the homologues chromosomes. In diploid homologues, chromosome are 2n where n is the number of homologues of each chromosome.

In haploid there is only one set of each chromosome and mainly takes place by meiosis. In aneuploidy is the condition where the number of homologues chromosomes are not as the normal genome of the organism for example in humans instead of 46 chromosomes there 45 or 47 chromosome found.

Answer:

Mediterranean climate

Answer:

The biology term, haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes

The term used to describe the number of chromosomes in a gamete would be haploid.

Gametes are usually formed by meiosis and meiosis is referred to as reductional division. When a normal diploid (2n) cell divides by meiosis, the daughter cells would have half the number of chromosomes of the parent cell. In other words, the daughter cells will have n number of chromosomes as opposed to 2n.

Cells with n chromosome numbers are generally referred to as haploid while those with normal 2n chromosome numbers are said to be diploid. Egg and sperm cells are haploid cells.

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.

During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.

For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

However, Let the probability that Joe and Sam are twins be = A

and the probability that they are not twins be denoted with B;

Then;

P(B) = 1 - P(A)

where;

P(A) = Probability of specific bands appearing on the gel in every one of them

[tex]P(A) =\Big( \dfrac{1}{15}\times \dfrac{1}{15}\Big)\times \Big( \dfrac{1}{450}\times \dfrac{1}{450}\Big)\times \Big( \dfrac{1}{32}\times \dfrac{1}{32}\Big)\times \Big( \dfrac{1}{70}\times \dfrac{1}{70}\Big)[/tex]

Answer:

Explanation:

RGD stands for Arginine Glycine Aspartate and is a three-amino-acid peptide. It is the most extensively utilized adhesive peptide for adhering diverse cell types to a variety of biomaterials. Integrins, fibrinogen,  osteopontin, fibronectin, and bone sialoprotein, as well as collagens and laminins, all include an RGD primary binding domain. As a result, the synthetic (artificial) peptide RGD may bind to a wide range of integrin types. The artificial RGD retains its functioning through the sterilizing and processing processes of biomaterial creation because of its recognition advantage. This feature denotes the immune reactivity and pathogen transmission during xenograft.

Affinity can be modulated by the conformation of artificial RGD. The efficacy of RGD is also determined by the in vitro deposition of cells on the surface of the material sample.

The molecular processes unravel its effectiveness throughout its use as a scaffold foundation in in-vivo models. The fact that artificial RGD cannot work well in isolation is now a major aspect that defines its activity.

It has been discovered that cells release a variety of integrin-binding proteins that are more effective in activating integrin signalling than pure RGD. As a result, most biomaterials will bind and adsorb these proteins rather than RGD. As a result, a serum-free medium is employed in the majority of in vitro research.

As a result, biomaterials are supplied with RGD as well as quasi polymers such as polyethylene glycol to reduce the variance produced by native proteins. The addition of additional amino acids to RGD based on natural sequences can increase its biological activity, which can aid in the development of new tissues and the stimulation of cellular responses and signalling.

The amino terminal endpoint of the peptide, as well as the carboxyl group of the material surface, establish a covalent connection, which binds the peptide to just the surface of its biomaterial. Cell adhesion biomaterials are made from a variety of cell adhesion materials, including poly-L-lysine, mussels adhesive protein (MAP), and outer membrane (extracellular matrix) proteins.

Because MAPS are high in Dihydroxyphenylalanine and lysine, RGD is coupled with either of these to boost its cell adhesion capability. As a result, they can also aid in the attachment to damp or moist surfaces. It may also firmly adhere to glass, metals, and plastics. The addition of thiol groups to a peptide can also aid in its orientation and boost its stability.

The gap and density of this peptide sequence and structure on the biomaterial surface may be adjusted using a micro and nanotechnology (nanoscale patterning) method, which also improves ligand binding accuracy. Cellular reactions and cell activity are also under its control. Integrin receptors have been shown to be between 9 - 12 nm in size, therefore nanoscale surface patterning is crucial.

As a result, the above methods serve as a strategy for incorporating a cell adhesion recognition domain into a biomaterial while taking into account all of the technical intervention affecting its quantity, type, and affinity to the top layer for cell adhesion as a functioning tissue rather than a monolayer.

the observations that chloroplasts and mitochondria resemble bacteria

Explanation:

The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).

Answer:

the observations that chloroplasts and mitochondria resemble bacteria

Explanation:

Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. ... Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.

In plant cells, the first part of mitosis is the same as in animal cells. (Interphase, Prophase, Metaphase, Anaphase, Telophase). Then, where an animal cell would go through cytokineses, a plant cell simply creates a new cell plate in the middle, creating two new cells.

Fishes use a different vision mechanism than mammals and other land animals. They have rods and cone photoreceptors to see the colorful visions and adjust their focal point by moving the lens closer to or away from their retina.

In the water bodies, a difference in the amount of light moves with the depth because water absorbs the light and this change occurs due to the optical nature of water.

The light bounces once it back in the retina, leads to the gain of the small packets of energy of light a second chance to be trapped by photoreceptors. However, vision remains blurry. The changes and distortion of the light-absorbing molecules present in the eyes of fishes make it tough to perceive a clear vision.
