When the muscle is stimulated, calcium ions are released from its store inside the sarcoplasmic reticulum, into the sarcoplasm (muscle ). ... The SR is smaller and less elaborate, and stores less calcium ions.

Answer:

Catastrophism, doctrine that explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations. ... This doctrine generally is associated with the great French naturalist Baron Georges Cuvier

The mechanism of catastrophism directly explains the process of fossil formation. It described the natural history that has been punctuated by catastrophic events that altered the way life developed and rocks were deposited.

Catastrophism may be defined as a type of geologic doctrine that significant changes in the earth's crust that have in the past been brought about suddenly by a series of events like mass extinction.

This catastrophic doctrine explains the differences in fossil forms encountered in successive stratigraphic levels as being the product of repeated cataclysmic occurrences and repeated new creations.

Therefore, the mechanism of catastrophism directly explains the process of fossil formation.

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:

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: 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%

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:

Hardy-Weinberg equilibrium is the principle of the genetic variation being constant. Each allele must be equally beneficial for a population to be in equilibrium. Thus, option C is correct.

Hardy-Weinberg equilibrium states the invariant nature of genetic variation when there are no disturbing factors in a population. For an equilibrium condition, the population should have a large size. Each allele must be equally beneficial so that there is no genetic drift.

There should be no immigration or emigration of the organism in a particular population as it affects the generation and individuals. Also, there must be no spontaneous mutations for the variation to occur.

Therefore, each allele must be equally beneficial for equilibrium.

A plant is placed near a window. Instead of growing straight up, the plant grows to the side. This plant demonstrates phototropism. Therefore, option A is correct.

A plant can maximize photosynthetic light absorption in the aerial portion and water and nutrient uptake in the roots by using phototropism, or the differential cell elongation displayed by a plant organ in response to directed blue light.

Auxin is a hormone found at the ends of leaves and stems that reacts to light. It enables the plant to grow in a way that is favourable to the light source.

She should tell the teacher because if she is unsure of what to do, the teacher can help her. If there is no teacher present, she should wash her hands and arms twice to remove as much of the chemical as possible. Then she should call a poison help or chemical help center if she is unsure of what to do next.

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

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.

recombinant DNA

Explanation:

In molecular biology, recombinant DNA molecules are genetic sequences formed by combining DNA material from different sources (i.e., organisms, populations, species, etc). Proteins produced from DNA recombinant molecules are known as recombinant proteins. Molecular cloning is the most widely used technique in molecular biology in order to produce recombinant DNA molecules. In this technique, a cloning vector such as, for example, a plasmid of a bacterium, is used to insert a foreign DNA fragment into another cell which is then expressed in the host cell.
