Answer:

A)Ocean floor evidence of sea floor spreading.

Explanation:

evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,

What is the tectonic theory?

The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.

What is a tectonic plate?

They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking that makes the ground shake During the earthquake and afterward, the plates keep on shaking until they are stuck again!

Explain natural selection and adaptations of bacteria

faust18 [17]

Natural selection can cause speciation, which increases the biodiversity of an ecosystem. Several bacterial colonies are placed on a petri dish that contains agar with antibiotics. After 24 hours, ninety percent of the original bacteria die, but the remaining ten percent survive and later reproduce.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where

Troyanec [42]

Answer:

$0.96$

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is $0.8$

As per Hardy Weinberg's first law of equilibrium

$p + q = 1\\$

Substituting the value of p in above equation, we get -

$q = 1-p\\q = 1-0.8\\q= 0.2$

q represents the frequency for white fur allele

Frequency of white fur phenotype is

$q^2\\= 0.2^2\\= 0.04$

Frequency of homozygous black fur phenotype (BB) is

$p^2\\= 0.8^2\\= 0.64$

As per Hardy Weinberg's second law of equilibrium -

$p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\$

Combined frequency of homozygous and heterozygous black fur phenotype is

$0.64 + 0.32\\= 0.96$

Why is it hard to find animals in tropical areas?

Rashid [163]

Answer:

Tropical areas are warm and wet causing for animals to want to hide essentially. Also there is a lot of cover for animals to hide in. Usually in tropical areas there are a lot of predators also, another reason for animals to hide.
