Describe why sexual reproduction allows for more variations in a population when compared to asexual reproduction.

Biology
1 answer:
kiruha [24]2 years ago
4 0

Answer:

Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. ... Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.

Reptiles are better suited to dry land than their amphibian ancestors because
Vaselesa [24]

Answer:

<u><em>All of the above.</em></u>

Explanation:

1. Their watertight skin minimizes moistures loss: <em>Reptiles have a reputation that they are “slimy” when we touch and hold them; however, they have dry skin, which has even fewer glands than mammals or amphibians. The main special feature of their skin is that the epidermis is heavily keratinized with a layer, which also prevents water loss.</em>

2. Amphibians must lay eggs in water or in moist soil to reduce moisture loss: <em>Because amphibian eggs don't have an amnion, the eggs would dry out if they were laid on the land, so amphibians lay their eggs in water.</em>

3. Reptile egg shells are harder than amphibians' eggs: <em>Reptile eggs are coated with a leathery or brittle coating, and the animals that hatch from them are miniature versions of the full-sized animal parent. In contrast, amphibian eggs are transparent and jelly-like. The animals that hatch from them still must go through metamorphosis.</em>

Compare and contrast the evidence that supports the two hypotheses describing how long, complex molecules that carry information
Rudiy27

Oparin and Haldane's theory and Miller's experiment are the proof that long complex molecules that carry information such as DNA, might have formed on early earth.

Explanation:

Oparin and Haldane Hypothesis states that life on Early earth could have evolved by chemical evolution.

Oparin and Haldane said that the reducing atmosphere of the early earth caused simple inorganic molecules to react by using sunlight and formed molecules like amino acids and nucleotides.

These monomers combined to form polymers, they would have attained self-replicating tendency eventually these would have assembled into structures and these macromolecules had also made membrane-bound organelle.

Although this hypothesis is not fully accepted but part of it which talks about formation of molecules is accepted.

Millers and Urey in their experiment created an artificial reducing environment like that of early earth. They used a heated pool of water, atmospheric gases like H2O,CH4,N2, NH4 and sparks of electricity. After running the experiment for some days they found that amino acids, sugars, lipids and other organic molecules had formed.

Their hypothesis is not fully accepted but part of is evident that organic building block is formed from inorganic constituent on the earth.

Growing a nursery of crop seedlings then transplanting them at the appropriate time is a facet of which agricultural technique?
Jobisdone [24]

Answer:

rice cultivation.

Explanation:

There are two methods of sowing a crop in the field i. e. sowing of seed and transplanting. Seeds sowing in the field is used for almost all the crops except rice in which transplantation is done. In transplanting method, plants are grown inside a nursery and when the plant reaches to a certain height, it is transported to the field. This method is done in the cultivation of paddy rice because water is present at a certain height in the field and rice is the only crop in which roots respire in water.

Which technology allows strands of DNA to be transferred from the cells of one species into the cells of another species?
Alex787 [66]

I believe the answer is Gene splicing because they remove specific genes in order to create a transgenic organism.

I hope this helps!
