Explain how natural selection could lead to a change in allele frequency leading to a change in the color of the frogs.
Pie

Answer:

Due to increasing the survival.

Explanation:

The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.

The RNA meets with the organelle ribosome that will read it to build a polypeptide chain of amino acids, following the process o
konstantin123 [22]

The rough endoplasmic reticulum (RER) is is a series of flattened sacs connected to ribosomes. The Golgi Apparatus is an organelle composed of flattened stacked pouches known as <em>cisternae</em>.

In this case, the missing words indicate:

  • Specifically, this organelle is attached on the ROUGH ENDOPLASMIC RETICULUM (RER) which will help to modify and package the polypeptide product.
  • It puts it into a transport vesicle to be sent over to the GOLGI APPARATUS  to add molecular tags and sort it, like a post office.

  • The RER is required for the production and secretion of different hormones and proteins.

  • The Golgi apparatus plays fundamental roles associated with the transport, modification, and packaging of proteins and lipids into vesicles, which are subsequently delivered to specific cellular destinations.

  • Both the RER and Golgi apparatus form part of the endomembrane system.

What structures work in antagonistic pairs to move bones?
Olegator [25]

Answer

Option C - Skeletal Muscles

Explanation

Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.
