<span>The correct answer is D. Active transport is the movement of a substance across a cell membrane against its concentration gradient (from low to high concentration instead of high to low, which is what naturally occurs as diffusion). </span>

The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require  the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />

Which type of epithelium is composed of multiple layers, including an apical layer containing tall, slender cells?
Mademuasel [1]

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

  • Simple squamous
  • Simple columnar
  • Pseudostratified squamous
  • Stratified squamous
  • Stratified columnar

Answer:

Stratified columnar

Explanation:

Epithelial tissue is the tissue formed by the cells which form a layer of cell and lines the lumen of the organ and also covers the organs. The epithelial tissue can be classified based on the number of layer and shape of the cell.

In the given question, the shape of the cell is slender and are tall therefore are called columnar. The cells form more than one layer or multiple layers therefore form stratified layers.

Therefore,  the epithelial tissue formed by these slender shaped multiple layers is known as the stratified columnar layer. The stratified columnar is present in the respiratory tract and the digestive tract.

Thus,  Stratified columnar is the correct answer.

How are photosynthesis and cellular respiration related apex?
pentagon [3]
Photosynthesis and cellular respiration are related in that; photosynthesis is a process that is tasked in making glucose which is then used in cellular respiration to make ATP. The glucose is then converted to carbon dioxide during cellular respiration, which is used in photosynthesis. Water on the other hand is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is  combined with hydrogen to form water.

Some cells contain two copies of each chromosome, and some cells contain only one copy of each chromosome. Which types of cells

I think it is skin cells and blood cells because sperm and egg cells are haploid, so they only have one copy. I’m honestly not 100% sure tho

What happens if the immune system fails to produce proteins called antibodies​
zmey [24]
If the immune system fails to produce proteins (Antibodies) it can cause a disease. This is because our immune systems are very needed so if our immune system decides to fail to produce its proteins, our body will become overwhelmed and could possibly cause us to die! :(
