Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the chromosomes are haploid or n. At which stage(s) of meiosis I are the cells diploid and at which stage(s) are they haploid
Answer:
Diploid → Prophase, metaphase, and anaphaseHaploid → TelophaseExplanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
Mitosis and Meiosis are the two types of cell division, in which the genetic material is replicated and transferred to the daughter cells.
The stages of meiosis in which chromosomes are diploid are prophase, metaphase, and anaphase. The haploid chromosomes are observed in telophase.
Meiosis is a reduction division in which genetic material is halved, such that a reduction in which diploid parent cells give rise to haploid daughter cells.
The stages of meiosis at which chromosomes are diploid and haploid are:
1. Prophase I is the first phase of meiosis I. The chromosomes are condensed and pair with the homologous chromosomes.
2. Metaphase I is characterized by the homologous pairs aligning at the equatorial plane.
3. Anaphase I is the independent separation of chromosomes, which migrate to opposite poles.
4. Telophase I is represented by the separation of chromosomes having a haploid number of chromosomes, which are now segregated into daughter cells.
Therefore, telophase I am the phase in which chromosomes are present in haploid numbers.

Explanation:
3.
Answer: Newton's Second Law of Motion
Explantation: Newton's Second Law of Motion is concerned with the effect that unbalanced forces have on motion. An unbalanced force acting on an object causes it to accelerate. The more mass the object has, the more inclined it is to resist any change to its motion.
4.
Answer: The First Law
Explanation: The first Law states that all objects have inertia. The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass which is roughly the amount of material present in the object.
5:
Answer: Newton's Third Law
Explanation: Newton's Third Law of Motion. Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts.

Answer:
The options are not complete, here are the remaining options from other websites.
d. divide uncontrollably and are immortal
e. have an extra set of chromosomes, which keeps them dividing.
The correct answer is divide uncontrollably and are immortal .
Explanation:
This because cancer cells are abnormal cells that divide uncontrollably and does not follow the normal cell cycle. abnormal cell that doesn't follow this cycle. Instead of them to die, the car continually reproduce more abnormal cells that can easily invade nearby tisssues. They can travel to all part of the lymph and body parts.

Gametes produced by the parents are shown along the __________________ and _______________ sides of the Punnett square.
Answer:
Vertical and horizontal
Explanation:
A punnet square is a tabular chart used in genetics to display the genotypic composition of the offsprings of two parents. To construct a punnet square, the alleles of the gametes produced by the parents is required.
The gametes produced by each parent via meiosis are placed along the vertical and horizontal sides of the punnet square. For example, if a cross occurs between two parents with the following genotype: AaBb and AAbb. The parents will produce the following gametes:
AaBb - AB, Ab, aB, ab
AAbb - Ab, Ab, Ab, Ab
These gametes produces by each parent will be placed along the sides (vertical and horizontal) of a punnet square to determine the genotype of the offsprings that will be produced.

Photography books
Field guides
Microbiology textbook
TV shows
Answer:
Field guides
Explanation:
Various species of plants and nimals exists some of which bears very similar resemblance but for some key differences which may be unknown to learners or observers. A field guide gives a description of plants and animals, stating key physical differences between similar plants and animals. This helps learners distinguish between the related organisms. Field guides are most useful when applied to habitats where a range of similar organisms have been spotted and the field guide is then taken to such habitat to physically identify each different plant or animal.

What is the objective for cloning
Answer:
the "productive" aim: to obtain selected organs, tissues and cell lines. The product of cloning would always be an organism-individual (with or without encephalon) obtained by cloning through nucleo-transfer having the selected genetic patrimony.
Explanation:
It's important to remember that cloning does not manipulate the animal's genetic make up nor change an animal's DNA. ... Cloning allows livestock breeders to create an exact genetic copy of an existing animal, essentially an identical twin. Clones are superior breeding animals used to produce healthier offspring.
The changes over time in the inherited traits of a type of organism are ____.
A) growth
B) biogenesis
C) spontaneous generation
OD) evolution
The changes over time in the inherited traits of a type of organism are known as evolution of the species. Thus, the correct option is D.
What is Evolution?Evolution is change in the heritable characteristics of biological populations which are taking place over the successive generations. These characteristics are the expressions of different genes, which are passed on from the parents generation to their offspring during the time of reproduction.
Variation in the genetic material tends to exist within any given population as a result of the genetic mutations and recombination. Evolution in a species occurs when the evolutionary processes such as natural selection and genetic drift act on this variation in species, resulting in certain characteristics which are becoming more common or more rare within a population than other traits.
Therefore, the correct option is D.

Answer:
is the first, and most general, mechanism of protection against pathogens
Explanation:
Innate or natural immunity is one of the two types of immunity an organism can possess (the other being; acquired immunity). Innate immunity is the FIRST defensive response of an organism against pathogenic attacks. The acquired immune system is only activated when the innate immune system has been penetrated or surmounted.
For example, the skin, mucus secretion, inflammation etc. are all natural or innate defenses against foreign invaders. Therefore, according to this question, innate immunity the first, and most general i.e. commonly used, mechanism of protection against pathogens.

Answer:
ok good question. pancreas is an organ which is found in both the exocrine and endocrine gland that's why sometimes it is called heterocrine. The outer portion of the pancreas(pancreatic islets) secrets the pancreatic juice,insulin and glucagon. let see them deeply: the insulin is a hormone secreted by the pancreas which is used for to lower the blood glucose method in appropriate standard they change it into glycogen and stored in liver. the other one glucagon undergoes a catabolic reaction of the glycogen to the glucose when the blood glucose level is very low so,the liver works in response of lower blood glucose level and the pancreas works in elevated blood glucose level thank you
