1. a wide variety of factors. heat, climate, weather, natural disasters that lower the population of prey animals, etc

2. well and example is this: it is getting hotter in Antarctica, causing the ice caps to melt. this change would make it harder for prey animals like penguins to find somewhere to live, thus making them easier food for predators. such as killer whales and polar bears.

3. the more trees we cut down to make room for buildings, for instance, causes many animals habitats to dissapear, the animals shortly after

son4ous [18]

Answer:

All pieces of land on Earth were once joined together.

Earth's surface is covered with continental plates.

All the continents are moving at a slow pace.

Explanation:

According to the Wegener, at first all continents are fuse together make a supercontinent which later broke apart into seven large masses of land. All the continents are moving away from each other at very slow rate. The surface of earth is covered with continental plates that is responsible for the breaking and movement of continents from each other.

Achondroplasia is a form of dwarfism in humans. It is caused by a mutant allele of the fibroblast growth factor receptor gene (F

ozzi

<h2>The correct answer is explained below:</h2>

Explanation:

According to the question, achondroplasia, a form of dwarfism, is caused by a mutant allele of the fibroblast growth factor receptor (FGFR) encoding gene.
This achondroplasia trait is dominant in nature. This is because presence of a single copy of the mutant allele results in the development of a dwarf phenotype.
Let the dominant mutant allele for the trait be represented by: A.
Let the recessive normal allele for the trait be represented by: a.
The individual with aa genotype is normal.
The individual with Aa genotype shows dwarfism.
The individual with AA genotype dies before birth.
As per the question, two people having achondroplasia have the genotype Aa.
Gametes produced by each of the individuals are, A and a.
Mating these individuals, we get the following possible offspring,

A a

A AA Aa

Phenotype Dies Dwarf

a Aa aa

Phenotype Dwarf Normal

The genotypes and the phenotypes of the possible offspring are represent in the Punnett square above.
The probability of the child to have achondroplasia is: $= \frac{2}{3}$ .
Since the child with AA genotype dies before birth so three (genotypes Aa and aa) out of four possible children survives.
