Hope this helped.
Some organisms that could not survive where cats, dogs, birds, horses, fish, cows, every animal that was in hurricane Katrina was affected by it. Some of these animals were able to survive and others were rescued from near death.
Most of the animals could not adapt to this change because they are not used to this type of change. The water was too strong for the fish and when the water brought the fish into any water/sea animal there was also medal because the water in through peoples houses (pretty much the man-made stuff that's not meant for sea is killing the animals in the water).
Any animal that was left behind was affected. The animals could not adapt to this change they have never experienced something that tragic before, how they survived? Well, the animals that survived was mainly because of there natural instinct, before an earthquake or anything hits there are many animals that can sense the storm coming before it even hits and in this situation, the animal could, wake up, run to owner, flee, run to higher ground, and if they cant sense it. They see whats going on around them and then they know something is wrong.
Answer:
They are sterile.
Explanation:
A mule is the offspring of a male donkey (jack) and a female horse (mare). Thus the number of chromosome of the donkey and the horse are quite different. A combination of the horse chromosome which is (64) and a that of the donkey chromosome which is (62) gives rise to 63 chromosomes in a Mule.
This major difference in number,forms and morphology typically prevents the chromosomes from pairing properly and producing successful embryos, as a result of this aftermath effect, it renders majority of the mules to be sterile.
The given question is incomplete the complete question is:
The legs of a human and the limbs of a cat are similar in structure. These structures are called ______ vestigial homologous analogous structures. This similarity indicates that ________humans evolved from cats cats evolved from the ancestors of humans cats and humans share a common ancestor .
1) A. Vestigial B. Homologous C. analogous
2) A. Humans evolved from cats B. Cats evolved from ancestors of humans C. Cats and humans share a common ancestor.
Answer:1. (B)Homologous and
2. (C) Cats and humans share a common ancestor.
Explanation:
Homologous structure can be defined as the two stricture in two different organism that appear similar.
They have evolved from the recent common ancestor so they are structurally similar. Due to adaptation of both of the organism in different environment their function is different.
Example: The limbs of humans are used for holding objects and performing various functions but the limbs of cats are used for walking.
They appear similar because their recent common ancestor is same. They are connected to each other because of ancestry.
