Mendel used more than 28,000 pea plants in his experiments. How did such a large sample size improve the reliability of his results?

A. Using many plants ensured that both males and females were available.

B. Using more plants made the experiments much faster.

C. Using more plants was necessary because some were unable to reproduce.

D. Using many plants gave results that supported his prediction of ratios. ​

Answers

Answer 1

Answer:

D. Using many plants gave results that supported his prediction of ratios. ​

Explanation:

Using more plants in any experiment, such as this one, will make the results more accurate.

By using more pea plants, Mendel's prediction was more supported by the results. A larger sample size will allow the ratios to be more reliable compared to a smaller sample size.

What impact do trees have on the food web?

Answers

Answer:

Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.

A pedigree chart is used to _______. (3 points)
A: predict percentage of offspring with a trait
B: predict genotypic probabilities
C: track inherited traits through generations
D: identify the genotype of parents

Answers

Answer:

A pedigree chart is used to track inherited traits through generations (option C).

Explanation:

A pedigree chart is a graphical representation, similar to a family tree, showing specific traits present in parents, children and relatives. It is a diagram commonly used in genetics.

A certain phenotype, product of genetic traits, is represented in a pedigree chart by pre-established symbols, which is useful for tracking inherited traits through generations.

The other options, predict percentage of offspring with a trait , predict genotypic probabilities or identify the genotype of parents require a Punnett square to be identified.

CELL DIVISION:

Cell division involves two processes namely: mitosis and meiosis. Mitosis results in two daughter cells that are genetically identical to one another.

Meiosis, on the other hand, results in four daughter cells that are genetically different from one another.

Mitosis and meiosis as types of cell divisions involves phases namely: prophase, metaphase, anaphase and telophase.

The major difference between prophase of mitosis and prophase I of meiosis is that homologous chromosomes, which are similar but non-identical chromosomes from each parent, are paired.

Describe what happened to beaver colonies after 1995 (when wolves were reintroduced). Then describe the relationship between the number of beaver colonies and the willow tree ring area.

Answers

Answer:

Decreases.

Explanation:

Decrease occurs in beaver colonies when wolves were reintroduced in the area because wolves feed on beaver and as a result, the population of beaver decreases. There is a direct relationship between the number of beaver colonies and the willow tree ring area because willow tree is a source of food for beavers so if willow tree are more in the area, more food available for the beaver and they will increase in number.

How do the colors of light affect photosynthesis? Which color was most efficient, medium and least?

Answers

Answer:

blue is the most efficient while green is the least efficient  

Explanation:

It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.

Neurotransmitters are defined by four essential characteristics. These are: Neurotransmitters are synthesized within presynaptic neurons. Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron. Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter. Their action in the synaptic cleft is terminated by a specific action. A, C, and D only

Answers

Answer:

The correct answer is A, C, and D only.

Explanation:

A neurotransmitter is a biomolecule, generally synthesized by neurons, which is poured from vesicles in the presynaptic neuron into the synaptic gap and produces a change in the action potential of the postsynaptic neuron. Depending on the nature of the neurotransmitter, this can be synthesized in the neuronal soma or in the nerve endings. Some neurotransmitters are synthesized directly in nerve endings thanks to enzymes that have been synthesized in the soma and transported to these endings. Through the interior of the axon flows a current of substances free or enclosed in vesicles, which can be precursors of both neurotransmitters or their enzymes, called axonal flow.Another characteristic of the transmitter function in each of the substances commonly accepted as neurotransmitters is that when administered exogenously as a drug that in reasonable concentrations perfectly mimics the effects of the endogenously released transmitter.

Neurotransmitters should be defined by four essential characteristics. It involved the A, C, and D only.

What are Neurotransmitters?

Neurotransmitters refer to the chemical messengers in the body that should transform the message from the nerve cell. Also, it should be synthesized in neurons and stored in the presynaptic terminal. It should be the vital attribute at the time when the chemical should mimic the activity of endogenous due to which it gets a similar response. Also it eliminates the activation site.

The chemical needs to have a selective effect on cancer cells--that is, it needs to harm cancer cells much more than it harms normal (noncancerous) cells.

You decide to run a new experiment to test the hypothesis that the fungus chemical harms cancer cells selectively. In this controlled experiment, you will test both cancer cells and normal cells under identical conditions. What data would support this hypothesis?

In the Hershey/Chase experiment phage proteins and DNA were radioactively labeled and allowed to inject coding material into bacteria. It was found that only radioactively labeled DNA was present in the bacterial cells which had been transformed. If radioactively labeled protein had been discovered in the transformed cells, what would this have told us about the molecules acting in genetics

Answers

A virus is made of two main components. A proteic capsid and genetic material. The Hershey/Chase experiment demonstrated that the virus introduces it's genetic material(DNA) inside the host cell to force it to make more viruses. This proved that genetic information is stored in DNA. If the marked proteins were found in the host cell that would have meant that proteins carry genetic information which they don't.

Answers

Answer:

The answer is when the cell express different genes.

Explanation:

Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
