Thermocline.
Explanation:
An ocean is a body of salt water which covers approximately 70% of the Earth's surface. About 97% of the Earth's water is comprised of ocean and as such it is the most prominent and defined feature of the Earth. There are basically four (4) categories of an oceanic basin and these are;
1. The Pacific ocean.
2. The Artic ocean.
3. The Atlantic ocean.
4. The Indian ocean.
A rapid change in temperature with depth is known as thermocline.
Basically, it is considered to be a thin but distinctive water region in a large body of fluid that is thermally stratified such as an ocean, in which temperature changes rapidly with an increasing depth.
This ultimately implies that, the temperature of water decreases rapidly (drastically) as the depth of water increases.

Explanation:
Cocci (in singular coccus) are spherical-shaped bacteria, while bacilli and spirilli are rod-shaped and spiral-shaped bacteria, respectively (in general, bacteria can be divided into these three categories by shape). Staphylococcus aureus forms irregular clusters of cocci (i.e., grape-like cocci) when viewed through a microscope.

Explain what causes lightning and thunder
Answers
Answer:
lightning and thunder is caused by the rapid expansion of the air surrounding the path of a lightning bolt. Since the lightning takes so little time to go from point A to point B, the heated air has no time to expand. The heated air is compressed, raising the air from 10 to 100 times the normal atmospheric pressure.
Explanation:
Question: Explain what causes lightning and thunder
Answer: Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. Lightning is extremely hot—a flash can heat the air around it to temperatures five times hotter than the sun's surface.

Explanation:
A certain regulatory gene is involved in controlling the expression of other genes. In studying this regulatory gene, a scientist discovers that it encodes for an enzyme that causes histone deacetylase (the removal of acetyl groups from histone tails). Based on this information, how would you predict that this enzyme regulates gene expression
Answers
Answer:
by an epigenetic mechanism
Explanation:
Epigenetics can be defined as the study of mitotically heritable gene expression changes that do not involve alterations in the DNA sequence. There are three different epigenetic modifications that work together either to activate or repress gene expression: DNA methylation, histone modifications (e.g., methylation, acetylation, phosphorylation, etc) and regulatory non-coding RNAs (e.g., long non-coding RNAs, microRNAs, piwi-RNAs, etc). Deacetylases are enzymes that play roles in epigenetic gene regulation by removing acetyl groups from lysine (K) residues located at the N-terminal end of histones H3 and H4. Histone deacetylation modifies the structure of the chromatin, thereby activating or suppressing gene expression in a context-dependent manner.

When an electric light is turned on, the amount of light energy released by the lightbulb is less than the amount of electrical energy going into the lightbulb. Which statement best explains this?
Question 4 options:
Some of the electrical energy is destroyed.
Some of the electrical energy is changed into heat energy.
Some of the electrical energy stays in the wire.
All of the electrical energy is destroyed.
Answers
Answer:
Some of the electrical energy is destroyed.
Explanation:
some of the electrical energy is destroyed because If the excess energy goes beyond the tolerance of the devices, they will overheat and/or burn (cause damage). ... If there is no interest in saving the extra energy, it can be "dumped" into an appropriate load and converted to heat.
When a lightbulb burns out, then that is when all of the electrical energy got desroyed, and that is why it happens over time
The statement that best explains this is some electrical energy is destroyed. The correct option is A.
What is electrical energy?Electrical energy is kinetic energy generated by moving electric charges. The amount of energy relies on the charge's speed; the faster it moves, the more electrical energy it carries.
Some electrical energy is destroyed because if the extra energy exceeds the devices' tolerance, they will overheat and/or burn (causing damage). If there is no desire to save the excess energy, it can be “dumped” onto a suitable load and transformed into heat.
When a lightbulb burns out, all of the electrical energy is destroyed, which is why it happens over time.
Therefore, the correct option is A. Some electrical energy is destroyed.

The yeast used to make beer can perform aerobic respiration or alcoholic fermentation. When O2 is available, yeast perform aerobic respiration, and when O2 is not available, yeast perform alcoholic fermentation. What is the advantage of aerobic respiration
Answers
Answer:
Aerobic respiration generates a high amount of energy compared to anaerobic respiration.
Explanation:
Yeast is a unicellular organism that belongs to the kingdom FUNGI. Yeast is a phenomenal organism being that it is capable of both aerobic respiration and anaerobic respiration depending on whether there is availability or not of oxygen.
Yeast undergoes a type of anaerobic respiration called FERMENTATION in the absence of oxygen but when oxygen is present, it undergoes aerobic respiration. Note that aerobic respiration, which includes glycolysis, Krebs cycle, and oxidative phosphorylation, produces the highest amount of energy in form of ATP. This amount ranges from 32-34 ATP molecules. This is the major reason why aerobic respiration is advantageous over the anaerobic respiration.

My pulse before the the jumping was slow and steadybuut after they were faster pace when I got done jumping. Their was a difference in the pulse rate it increases because your doing physical activity which cause you to pump more blood around.
There's a difference in the pulse of an individual after jumping because the pulse increases after physical activity.
A pulse rate simply refers to the measurement of the heart rate of an individual. It's also referred to as the number of times that the heart of a person beats per minute.
It should be noted that the pulse rate of a person will increase after an exercise. Therefore, after jumping, the pulse rate will increase. This means the heartbeats per minute rise.

Gametes, which are sex cells, carry the alleles. Why must a gamete carry one allele (represented by a letter) from each gene? Meaning, why can’t a gamete carry an “hh” instead of an “hs” or an “Hh” instead of a “HS?”
Answers
Answer:
Due to the law of independent assortment
Explanation:
In diploid species like humans, all somatic (body) cells have two complete sets of chromosomes, one chromosome inherited from the maternal gamete and one chromosome inherited from the paternal gamete. Each one of the homologous chromosomes contains one copy of each gene, or allele, such that one allele is inherited from each parent. According to the law of independent assortment, maternal and paternal chromosomes are independently assorted during meiosis, which means that different genes localized on different chromosomes are randomly distributed into gametes. In consequence, alleles of different genes are transmitted from parents to offspring independently of one another.

Candy bars are well known to supply large amounts of energy for metabolism. With all this energy trapped inside, how can the candy bar sit still on the shelf in the grocery store
Answers
Answer:
Energy is stored as potential energy
Explanation:
Candy bars are primarily made of glucose (and other types of sugars), which contain many covalent bonds that store potential energy. The reason why a candy bar can sit still on the shelf is because covalent bonds are very stable. However, when you eat the candy bar, your body has enzymes that can metabolize the candy, breaking down the covalent bonds and releasing all that "trapped" energy inside.
