Fur seals and sea lions have similar anatomy. They probably have a common ancestor.

Answers

Answer 1
It's long been assumed that marine mammals in the pinniped group – seals, sea lions and walrus – evolved from a land-based common ancestor, but until now, no definitive fossil evidence had materialized.

which of the following is NOT a component that energy from the sun affects?​

Answers

Answer:

No pictures .......But an educated Guess

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

Why do asexually reproducing organisms not benefit from recombination? Explain.

Answers

Answer:

Explanation:

While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.The key difference between sexual and asexual reproduction is that sexual reproduction involves two parents of the opposite sex while asexual reproduction involves a single parent.

The ability to reproduce and produce a new generation of the same species is one of the fundamental characteristics of a living organism. It involves the transmission of the genetic material from the parental generation to the offspring generation, ensuring the characteristics of the species and perpetuating the characteristics of parental organisms. Before a new individual reaches its own reproductive stage, it normally has to go through a period of growth and development. Some members of the species will die before they reach reproductive age due to predation, disease and accidental death. So the remaining species will only able to produce more offspring and contribute to the continuation of the species. There are two basic types of reproduction; namely, asexual and sexual reproduction.

Answer:

Recombination only occurs when 1/2 of the strand from each parent is used, in which parts of the strand may be used to create the new strand. Asexually reproducing organisms don't benefit rom recombination, because frankly there is no other strand in which recombination can be used. Instead, the most the recombination can occur is within it's own strand, which means that essentially there is less combinations then if two strands are used. As such, asexually reproducing organisms would look more or less the same.

Some factories have started using large tanks of bacteria to remove carbon dioxide from the atmosphere. As more factories start to do this, the amount of carbon dioxide in the atmosphere could decrease over time. If this happens, and if energy coming from the sun and the amount of carbon dioxide being put into the atmosphere otherwise stay the same, what would happen to the total amount of energy in the Earth system and to global average temperature

Answers

Answer:

The carbon dioxide in the atmosphere will be reduced if more factories started using bacteria to capture carbon dioxide

Explanation:

There will be more that will reach the Earth System than exited as combustion introduced carbon dioxide to the atmosphere, so the total amount of energy in the system will increase.
