In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.

Bacterial communities differ in their species makeup, the niches they occupy, and the effects they have on various ecosystems.

Communities defy a single, fundamental definition due to their complexity. Instead, they offer fascinating illustrations of dynamic processes that vary with ecological size. In the beginning of microbiology, there were difficulties in describing and classifying communities.

Robert Koch revolutionized the study of microbiology in the late 1800s by inventing his techniques for proving the link between an infection and an organism (Koch, 1876). Koch's hypotheses continue to be the "gold standard" for linking germs to illness or any other interesting event.

Therefore, In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.

Answer: b

Explanation:

Answer:

Simple dominance is when the dominant gene in a heterozygous organism expresses the dominant phenotype. Incomplete dominance is when a heterozygous organism exhibits a blending of both genes, recessive and dominant. Red and white flowers will "blend" and make pink flowers.

Incomplete dominance, only one allele in the genotype is seen in the phenotype. In simple dominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Answer: Determining a substance's physical or chemical identity. What are the two main requirements for identification? The adoption of testing procedures that give characteristic results for specific standard materials and the number and type of tests needed to identify a substance to exclude all other substances.

Answer: A. All were tall.

Explanation:

True-breeding plants are plants with completely dominant or recessive genotypes (TT (tall) and tt (short), for this example). He crossed one tall plant with genotype TT with a short plant with genotype tt. Set up a Punnett square with parents TT and tt.

All offspring will have the genotype Tt. T is dominant, so only one copy of it is needed for a plant to be tall. All of the offspring have one copy of T, so they're all tall.

Answer:

O hydrogen bonds

ionic bonds

Explanation:

DNA is composed of two strands of nucleotides that are held together by hydrogen bonds. Hydrogen bonds are relatively weak bonds that form when a hydrogen atom is shared between two electronegative atoms, such as oxygen or nitrogen.

Due to the unequal distribution of the hydrogen atom between the two atoms, one of them develops a partial positive charge, while the other develops a partial negative charge. The resultant hydrogen bond between the two atoms acts as an attracting force.

Proteins and nucleic acids, including DNA, have secondary and tertiary structures thanks to hydrogen bonding. Between the two strands' nitrogenous bases in DNA, hydrogen bonds develop.

Each base, including guanine, adenine, thymine, and cytosine, has a distinct structure that enables hydrogen bonds to form with the corresponding base. For instance, adenine and thymine form two hydrogen bonds, whereas cytosine and guanine form three hydrogen bonds.

These hydrogen bonds hold the two strands of DNA together, allowing them to form the double helix structure. Without hydrogen bonds, the strands of DNA would not be able to stay together, and the genetic information contained in DNA could not be passed on.

Answer:

the food that we eat are used up by the cells to perform different activities such as metabolism.

Answer:

by performing a bioinformatic analysis in order to discover Y chromosome-linked mutations associated with defective phenotypes. In this case, it is expected to discover two or more loss of function mutations located in the coding region of the target gene on the Y chromosome in different males, and then associate such mutations with altered phenotypes caused by the inactivation (loss of function) of this gene

Explanation:

The genes located on the Y chromosome exhibit a uniparental mode of inheritance (i.e., these genes are only transmitted from father to their sons). This situation makes difficult to map the target gene since recombination does not occur for genes that are only located on the Y chromosome, hampering the development of a linkage map containing this gene. In this case, it is possible to directly associate genetic mutations located at the same genomic region (locus) on the Y chromosome with a particular altered phenotype in males carrying these mutations, which can be in principle associated with the inactivation of the target gene (loss of function mutations) in these individuals.

Answer:

1) Natural selection

2) Hypothesis: The excessive use of FQ antibiotics on chickens leads to the fixation of new genes -by natural selection- that result from mutations in the bacterial genetic material, which makes these cells become even more resistant to the drug.  

Explanation:

1) Natural selection selects beneficial alleles and increases their frequency in the population.

Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.

In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitat.  

Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.

So, in the exposed chickens´ example, we are focussing on bacteria populations.

2) Hypothesis.  

First, remember that the hypothesis is a conjecture.   The researcher hypothesizes in order to predict what is going on or what is expected to occur. A hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.

So in this example, we want to correlate the use of antibiotics with bacteria resistance.

I would hypothezise as following,

The excessive use of FQ antibiotics on chickens leads to the fixation of new genes -by natural selection- that result from mutations in the bacterial genetic material, which makes these cells become even more resistant to the drug.

This hypothesis probably states the same as yours but turns to be more concise. The hypothesis needs to go to the point. If you want to be more specific, you can probably add some specific hypotheses to dig into your work.

We have that the,Natural selection caused the FQ antibiotic resistance.

Generally , Natural resolution causes a reaction that leads to antibiotic resistance, Mutation in micro organism make them resistant to antibiotics and when they reproduce similarly ,they will pass by this resistant trait to their offspring, which will outcomes into a completely resistant generation.

In the give up ,result is a populace of in most cases resistant bacteria.

Answer:

B adaption

Explanation:

The scenario in which the Pandas evolve longer wrists to better eat bamboo over a long period will increase the possibility of artificial selection. The correct option is A.

Artificial selection, also renowned as "selective breeding," is the practice of selecting for positive traits in agricultural products or animals rather than allowing the species to change and evolve naturally, as in natural selection.

The process by which organisms can choose individual lifeforms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve.

Adaptation entails dealing with both the physiological abiotic environment such as light, dark, temperature, etc. but in addition to the intricate biotic environment.

Pandas evolved longer wrists to better eat bamboo over a long period of time and this in turn increase their possibility of survival. This is an example of artificial selection.

Thus, the correct option is A.
