Dr. Fatima was investigating the pathways in photosynthesis. She observed a set of chemical reactions whereby electrons were getting excited and energy carriers were being made and water was splitting. What process was she observing?

A. Krebs cycle

B. Light Reactions

C. glycolysis

D. Calvin cycle

The results show Sarah could feel tired because her red blood cells (2,700,000) and platelets (245,000) are below the normal levels (3,800,000 and 250,000). Her white blood cells (9,000) are above the normal level (8,500)

Answer:

Condensation

Explanation:

Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.

Answer:

Condensation

Explanation:

Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.

Answer: We are given:

Mass of solvent (water) = 100 grams

Mass of solute (NaCl) = 20 grams

Mass of the Solution:

Mass of Solution = Mass of Solute + mass of Solvent

100 + 20 = 120 grams

Mass Percent of NaCl:

We know that

mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100

replacing the variables

Mass% of NaCl = (20 / 120)*100

Mass% of NaCl = 100 / 6

Mass% of NaCl = 16.67%

Explanation:

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Answer:

The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell

Explanation:

Cell membrane is selectively permeable in nature. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment and hydrophobic tails form an oily layer inside the membrane. Thus, correct option is A.

Plasma membrane is also known as the cell membrane. It is found in all types of cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is also found which covers the cell membrane.

The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. Plasma membrane is selectively permeable in nature, it allows only some material to pass through it while blocks other material from entering through it.

The portions of the integral membrane protein found inside membrane are hydrophobic, while portions which are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic in nature. Molecules that are hydrophobic can easily pass through the plasma membrane while hydrophilic particles cannot pass through the membrane easily.

Therefore, correct option is A.

Cellular respiration process do plants and animals share in common. So, the correct option is (B).

Cellular respiration is defined as the process that occurs in the mitochondria of all living organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).

This process is a set of metabolic reactions that occur inside cells to convert the biochemical energy obtained from food into a chemical compound called adenosine triphosphate (ATP). Metabolism define as the set of chemical reactions carried out to maintain the living state of cells in an organism which can be divided into two categories:

Answer:

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

Explanation:

The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.

Normal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.

While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

Answer:

vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)

Explanation:

RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.

Answer:

To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed

Explanation:

Using the Pearson’s Square calculations:

1. Subtract across the diagonal:

a. 18% - 12% = 6 parts soybean meal

b. 18% - 22% = 4 parts corn

2. Sum the parts:

a. 6 parts soybean meal + 4 parts corn = 10 totalparts

3. Divide each part by the total to calculate the percentage of each feed to include in the ration:

a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal

b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn

So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),

60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal

40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn
