what is the relationship between gens , cromosomes, and DNA
Answer:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Explanation:
While you were on safari, your friend got bit on the leg by a posionous snake and nearly died from excessive hemolysis. Being a true scientist, you captured the snake and analyzed its venom to understand why it caused hemolysis. You found thwo enzymes, a protease (breaks down proteins), and a phospholipase. He isolated each of these enzymes and treated red blood cells with them. He found that only phospholipase caused red blood cell lysis. He also found that, after treatment of red blood cells with the phospolipase, there was excess amounts of free phosphophorylcholine (Choline phosphate group) and free diacylglycerol (glycerol with two hydrocarbon tails). 1.) What is the substrate for phospholipase and where does it cleave
Answer:
Phospholipase is an enzyme, which is classified into phospholipase A2 and phospholipase A1.
In this case we are talking about phospholipase A2, that is why the sn-2 ester bond of glycerophospholipids will be taken as a substrate, giving fatty acids as a product, such as arachidonic acid.
Explanation:
The glycerophospholipids used by this enzyme are those found in cell membranes, these pathways are usually associated with inflammation pathways for the formation of arachidonic acid that functions as an immunological mediator.
On the other hand, it must be remembered that membrane phospholipids are amphipathic, that is, with hydrophilic and hydrophobic molecules and are responsible for balancing the internal homeostasis of the intracellular environment.
QUESTION 2
When you exercise, you get warmer. Name the process that goes on inside all the cells of your body, resulting in the production of
heat.
Thermogenesis is the process which produces heat in the body.
Body temperature is increased with exercise because your body's muscle moves continuously. Thermogenesis is the process through which our body's muscles, organs, and brain produce heat. Our muscles produce heat by shivering.
Hormonal thermogenesis is the process through which thyroid gland releases hormones in order to increase metabolism. This increase in the metabolism produces heat in the body and rises the temperature in the body so we can conclude that through thermogenesis our body produces heat.

By what factor (how much) does the milli- unit differ from the centi- unit?
earth science
Answer:
By a factor of 0.1.
Explanation:
Hello,
In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:
[tex]\frac{milli}{centi}= \frac{0.001}{0.01} =0.1[/tex]
It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:
[tex]\frac{centi}{milli}= \frac{0.01}{0.001} =10[/tex]

During which phase does the cell actually separate into two individual daughter cells?
Answer:
During which phase does the cell actually separate into two individual daughter cells? Explanation: Cytokinesis is the phase during which the cytoplasm of the cell divides and the cell actually separates into two cells. The term cytokinesis actually means cutting (kinesis) of the cytoplasm.
Explanation:
The parent cell separates into two individual daughter cells in the cytokinesis phase of mitosis. Details about cytokinesis can be found below.

What is cytokinesis?Cytokinesis is the process in which the cytoplasm of a cell divides following the division of the nucleus.
Mitosis is the biological process by which living cells replicate themselves and create offsprings.
Mitosis primarily involves the division of the nucleus while Cytokinesis is the division of parent cells into daughter cells.

Explain how the bacteria and animals around the hydrothermal vents showed scientists that life was much more adaptable than they had believed.
Explanation:
Well, its extremely hot in the hydrothermal vents. Scientists simply believed it would be impossible for anything to survive due to the heat. Bacteria and micro-organisms were able to adapt to growing there, though. So in short words, they survived extreme conditions teaching scientists that life was quite adaptable.

Which two processes allow water to enter the atmosphere?
evaporation and transpiration
precipitation and condensation
condensation and evaporation
transpiration and precipitation
Answer:
its c) condensation and evaporation
Explanation:
Evaporation and transpiration are the two processes that allow water to enter the atmosphere. The correct option is A.
What is transpiration?Transpiration is the method by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and water from the stem and roots moves upwards or is started to pull into the leaves.
The direct impact of transpiration is that it regulates plant temperature and provides water for photosynthesis. It also transports nutrients and sugars through the plant's vascular tissues.
Evaporation is a way of vaporization that occurs on the surface of a liquid as it transitions from the liquid phase to the gas phase.
Both of these process aids to enter water into the atmosphere.
Thus, the correct option is A.

8 incisors. 4 canines, also called cuspids. 8 premolars, also called bicuspids. 12 molars, including 4 wisdom teeth.
Human: deciduous teeth: 212/212; adult = 2123/2123. Both childhood molars are replaced by adult premolars. Adult total is double the formula = 32. Opossum: 5134/4134 (one less incisor on each side of the lower jaw).
HOPE THIS HELPED
[tex]\huge\bold\red{Answer:-}[/tex]
The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.
The dental formula for milk teeth in humans is:
[tex] \frac{2102}{2102} = 2[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth hence the zero.
The dental formula for permanent teeth in humans is:
[tex] \frac{2123}{2123} = 32[/tex]
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.

Answer:
The correct answer is "Orthologs are homologs found in the same species".
Explanation:
Orthologs, or orthologous genes, are defined as genes found in different species that evolved from a common ancestry. Therefore, It is false to affirm that orthologs are homologs found in the same species. Orthologous genes have the same function and often share common nucleotide sequences, however, they must be found in different species to be considered orthologs.

what is cell theory ?Cell theory is widely accepted view of origin of life on Earth functions, all organisms are made of either single cells or a group of cell create tissues, organs, and organisms.
Three major hypothesis of cell theory are all organisms are made of cells, Second, cells are the building blocks in the creation of tissues, organs, and entire functioning organisms. The third is the cells can only arise from other cells or pre-existing cells.
Two scientists called Theodor Schwann and Matthias Jakob Schleiden first developed the cell theory in the year of 1839, along with Rudolf Virchow another scientist who contributed to the theory.
Schleiden explained that the structural part of a plant was made up of cells and a crystallization process either within other cells or from the outside cells. Theodor Schwann explained that the structures of animals are composed of cells.
The modern cell theory explained some postulates like All living things are composed of one or more cells, arise from pre-existing cells by cell division, fundamental unit of both structure and function in living organisms.

. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.
