why do you think using a person's own cell to make a new organ or tissue for them will increase the chance that their body will accept the transplant?

What is the process called when two glucose molecules bond together to form a
disaccharide and why is it important.

Answers

Answer:

Dehydration reaction (a condensation reaction)disaccharide will provide energy for chemical reactions in the body to take place.

Explanation:

The Condensation Reaction is an organic reaction in which two molecules combine to give a single product accompanied by the formation of a molecule of water H2O. Disaccharides are produced when two monosaccharides are chemically combined. The bond called O-glycosidic, is the bond by which monosaccharides join to form disaccharides or polysaccharides. In this type of bond, an OH group of an anomeric carbon of a monosaccharide reacts with an OH group of another monosaccharide, releasing a water molecule.The main function of disaccharides is to provide energy to the cells of the human body, or glycogen. This is achieved through enzymes that act in the synthesis of the disaccharide, extracting glucose. Among the main and best known enzymes that act in this process are insulin for sucrose, lactase for lactose, and trehalase for trehalose.

Yall Im struggling, if u cant read it, the question is “why does a mountain climber need an oxygen supply at very high altitudes, even tho the air still contains 21% oxygen?

Answers

Answer: Because it is harder to draw breath in. And the cold

Explanation: At higher altitudes, it becomes more dangerous, and you can develop altitude-related illnesses such as HAPE and HACE. I read a book called Into Thin Air, and in the book the author goes into detail on the details/complications of climbing Mt.Everest and oxygen needs. Mountain climbers use canisters of oxygen called Supplemental Oxygen.

how does cell division help in growth and development of somatic cells and in gamete formation?

Answers

════════ ∘◦❁◦∘ ════════

[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]

════════════════════

Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.

#see pic of how cells in our body divide during mitosis

#sorry i borrow this ans for my latex experiment :v

════════════════════

Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

List the four steps of mitosis in order. Describe what is happening during each phase.

Answers

Answer:

The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.

A scientist compares two samples of white powder. One powder was present at the beginning of an experiment. The other powder was present at the end. She wants to determine whether a chemical reaction has occurred. She finds that neither sample bubbles or dissolves in water. She measures the mass and volume of the solids. Sample one has a volume of 45 cm3 and a mass of 0.5 g. Sample two has a volume of 65 cm3 and a mass of 1.3 g. What should the scientist conclude?

A.
The samples have the same color, so no chemical reaction has occurred.
B.
The two samples do not react with water, so no chemical reaction has occurred.
C.
The densities of the samples are different, so a chemical reaction has occurred.
D.
The densities of the samples are the same, so no chemical reaction has occurred.
E.
The densities of the samples are different, so no chemical reaction has occurred.

Answers

Answer:

I think it is C because there densities are different.

Why is it important to know the average mutation rate when using DNA comparisons to determine
how long ago lineages split?

Answers

Answer:

mutation rates can be used to design molecular clocks in order to estimate divergence times among species  

Explanation:

In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).

Answers

Answer:

two tectonic plates slide past each other underwater, causing a large movement of water large ocean waves form .large ocean waves move in all directions away from the shifting plates .large ocean waves slow down and increase in height as they reach the coast

Explanation:

Tsunamis are initiated underwater and usually happen as a result of underwater earthquakes which can be initiated when tectonic plates slide past each other.

This causes a large movement of water such that large waves form and move away in al directions from the source. As these waves approach the shore they slow down speed but this only increases their height such that when they make landfall the effect could be devastating.

If a mutation results in an organism with new characteristics then eventually a new species will be formed if more such mutations will continue to accumulate in the individual. Mutations result into the accumulation of variations in an individual and when such variations keep on accumulating in a particular organism consistently it leads to formation of a new species or we can say that evolution has occured.

A mutation is a random change in DNA which therefore affects a gene and/or chromosome. Most mutations have no effect on the phenotype. Some influence phenotype to some extent. Very few create a new phenotype. Mutations can be inherited and therefore passed on from one individual to another. If a mutation causes a new phenotype that makes an organisms better suited to a particular environment, it can lead to rapid change in the characteristics of the individuals in that species.
