Explanation:

Proteins are being transported along the endoplasmic reticulum.

The endoplasmic reticulum is a membrane system within the cytoplasm. Apart from increasing the surface area within the cell, this continuous system also carries out protein folding, synthesis and transport.

Further Explanation:

Most proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes in the rough endoplasmic reticulum ER.

The rest of the ER, which does not contain ribosomes is called the smooth ER, and may contain lipids, enzymes, and other proteins. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen

If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?

oksian1 [2.3K]

The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.

Which increase the rate of soil formation? Check all that apply.

Rainbow [258]

Answer:

large grain sizes, more precipitation, warmer temperatures.

Explanation:

Soil is the thin layer of material covering the earth's surface and they are usually formed through the process of weathering of rocks. The soil consists of mainly mineral particles, organic materials, air, water and living organisms and they interact with each other.

Large grain sizes, more precipitation, warmer temperatures are the factors that increase the rate of soil formation.
