Answer:

These agents are known as teratogens.

Explanation:

Teratogens impair or cause abnormal development and growth of the embryos or fetuses exposed to them. During prenatal development, the embryonic stage is the most susceptible to teratogens because at this time there is formation of major organs and limb buds. Birth defects are a common sign of such exposure.

a male guinea pig is homozygous dominant for hair texture and hair length. A female guinea pig is heterozygous for hair texture
nekit [7.7K]

If we talk about guinea pigs, the trait of hair length is controlled by a gene with two alleles.

Allele for short hair (S) is dominant on the allele for the long hair (s).

The texture of hair texture  is controlled by a gene with two alleles. It can be rough or smooth, and the allele for rough hair (R) is dominant on allele for smooth hair (r).

Now coming towards the question:

  • A female guinea pig is heterozygous for hair texture and homozygous recessive for hair length.

Phenotype of the female will be Rough and long hair.

  • A male guinea pig is homozygous dominant for hair texture and hair length.

Phenotype of the male will be Rough and short hair.

Explain why a volcano is created when oceanic and continental crust collide. Makes sure you include what
pav-90 [236]

Oceanic crust or a less solid piece of oceanic crust will subduct beneath continental crust. Earthquakes occur when the oceanic plate subducts into a trench. Volcanoes are created by the melting of mantle material.

<h3>What does oceanic crust mean?</h3>

The outermost part of the Earth's lithosphere, known as oceanic crust, is created at spreading centres on oceanic ridges that are found at divergent plate boundaries and is found beneath the oceans. The oceanic crust is roughly 4 miles (6 km) thick. Even without the sediment on top, it is made up of many layers.

<h3>What is a characteristic of oceanic crust?</h3>

Compared to continental crust, oceanic crust is both thinner and denser. This is because to the oceans' weight, which has compacted it beneath it. It is also much more recent than continental crust, typically existing within the last 200 million years.
