Which of the following clades is most likely to survive a series of catastrophic events over time? (1 point)
marishachu [46]
The correct options are as follows:
1. D.
<span>A clade refers to a group of organisms that are made up of evolutionary descendants that originated from a common ancestor. A clade that will survive a series of catastrophic events must be one that is made up of distantly related and diverse species. This is because, those species will have different type of adaptability capacity and will be able to adapt in different ways to the catastrophic events. Due to the differences in their ability to adapt, some of the specie will survive the catastrophic events even if others are wipe out.

2. B.
The mass extinction of one specie usually creates space for another new specie to survive. The new specie that survive the old one may possess the ability to adapt to the event that wipe out the former set of living organisms and thus, the new specie will be able to occupy and reproduce in their new space. Mass extinction is said to occur when the whole population of living organism living in an ecosystem are wipe out as a result of unfavorable conditions.

3. B.
Convergent evolution refers to the independent evolution of similar features in species that arise from different lineages. The species involved usually evolve these traits as a result of having to adapt to similar environments. Convergent evolution usually result in evolution of analogous structures, that is, structures that have similar forms or functions but which are not present in the last common ancestors of the species.

4. C.
 In evolution, gradualism refers to theory that states that evolution occurs slowly and gradually, thus, large changes in evolution are actually product of small changes that occur over a long period of time. The theory of gradualism was originally proposed by James Hutton in 1795.

 5. C.
Mass extinction refers to the wiping out of a a large number of species within a very short time. Mass extinction can occur as a result of severe unfavorable conditions that all the species in an ecosystem can not adapt to. An instance of this is a drastic decrease in global temperature after several massive volcanic eruptions.</span>

After injuring his knee kai began having pain and numbness in his lower leg. the doctor said the injury damaged nerves that run
Leno4ka [110]

Damage to the nervous system is causing Kai to have pain and numbness.  

<h3><u>Explanation:</u></h3>

Kai injured his knee. We know that the posterior surface of the knee has the quadrangular fossa which is guarded by the tendons of hamstrings anteriorly and by the two heads of gastrognemus muscle below. There are several nerves running down the leg through this region.

Any trauma to this fossa can cause these nerves to get damaged. Thus it can lead to numbness of lower limb. Proper physiotherapy is required to recover as soon as possible. Else that can even lead to paralysis of lower limb.

PLEASE HELP I only have tomorrow morning to get my grade up.
Anika [276]

oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.

i hope you will get some knowledge from here❣
