Answer:
A
Explanation:
This is because water is the densest medium among the three. This means there are more molecules of the material per unit volume as compared to the other media. Therefore, a ray of sunlight in water bombards with many molecules in its straight path as compared to in atmosphere or vacuum. This slows it down and diffusing it. This is why light does not get to great depths in oceans and some deep lakes leaving these deep layers of water, dark. In vacuum, light can travel the farthest, followed by the atmosphere, then water.
Answer:
The walruses that had thicker fat layers were more apt to survive and live to reproduce
Answer:
The correct answer is b.
Explanation:
In the endocrine system, the signaling molecule or hormone is produced by a gland and discharged into the blood where it travels until it reaches certain cells distant from its place of origin on which it acts. In autocrine communication, the signal produced by a cell regulates the cell that produced it, that is, it is when the cells send messages to themselves. In autocrine signaling, a cell releases a hormone that acts on the same cell. This occurs between cells that are relatively close together and the existence of a specialized structure is not necessary, being a local communication.
Answer:
The correct answer would be - functions.
Explanation:
The structure of the skin cells and muscle cells are different and have a different number of cell organelles on their role in the body. Skin cells are a special type of cells that keep on shedding and replaced by new ones therefore they need less energy and have many mitochondria.
In contrast, muscle cells have different structures as they need a high amount of energy to make movements and therefore have lots of mitochondria in the cell.
Answer:
quantitative analysis
Explanation:
Qualitative analysis refers to quality whereas quatitative analysis refers to the amount or quantity. In this experiment, we see how much carbondioxide gas is produced after the use of different carbohydrates given to the yeast. In this experiment, we want to know the concentration of the product in the reaction not the quality so we can say that this experiment shows quantitative analysis as compared to qualitative analysis.
