I’m ____ mating partners come close to one another and release eggs and sperm

Biology

Tasya [4]3 years ago

I  believe the "I'm" is supposed to be "in" and if so then the correct nswer would be External Fertilization... because as the name suggests, external fertilization means fertilization takes place outside the body of the organism. In this process, mating partners release eggs and sperm outside their body, which then undergo fertilization.


External fertilization occurs in aquatic animals ( like fishes) as the presence of water gives sperm a medium to travel to the eggs and fertilize them.

A population of lizards lives in a marsh near the ocean. Members of this population have striped tails that can be yellow, orang
ladessa [460]

The question is incomplete as it does not have the options which are:

A. Speciation

B. the founder effect

C. natural selection

D. gene flow

Answer:

Founder effect

Explanation:

The founder effect is the phenomenon observed when the members of the population establish a new population.

This effect is observed due to the immigration and emigration of the individuals of the population.

In the given question, the four lizards swept away with the ocean and reached a new island. There they reproduced and flourished and by the time they formed the new population with orange stripes. This is the case of the genetic drift especially the founder effect in which the new alleles for the orange tail expressed.

Thus, the founder effect is the correct answer.

katen-ka-za [31]

Answer: The correct answer is-

C.They replaced carbon dioxide with oxygen in the atmosphere.

Cyanobacteria ( also known as blue green algae) is a large phylum of bacteria that is capable of synthesizing its own food using carbon dioxide and water in the presence of sunlight ( photosynthesis).

They contain a green pigment called chlorophyll that absorbs energy from sunlight and helps in the formation of food ( glucose). They release oxygen as a byproduct in the atmosphere.

As these organisms utilize carbon dioxide ( that is present in the atmosphere) to give oxygen in return, therefore, they affected early atmosphere of Earth by replacing carbon dioxide with oxygen.

Thus, option C) is the right answer.

Explain how horned toads squirting blood from their eyes is a particularly good defense against coyotes.
coldgirl [10]

Answer:

A stream of nasty-tasting blood squirts from the toads eyes, straight into the coyote's mouth. The coyote steps back, shaking its head from side to side in disgust. It retreats, wiping its muzzle, while the uninjured toad skitters away to safety.

Explain how this experiment showed that gene flow was not the cause of antibiotic resistance.
Alenkinab [10]

Answer:

Due to no transfer of resistance allele.

Explanation:

The gene flow was not the cause of antibiotic resistance because the characteristics can't be transferred from one generation to the next generation. The organisms are evolved to become an antibiotic resistance due to their environmental conditions and this resistance quality is only present in the existing population and the alleles that are responsible for this resistance can't be transferred from the bacteria to the next generation so the experiment showed that gene flow was not the cause of antibiotic resistance
