Why does the moon get smaller and disappear?

Answers

Answer:

why does the moon get smaller and dissapear?"

Explanation:

One of the questions that ancient mythology would try to answer would be "why does the moon get smaller and dissapear?" Ancient mythology stories always try to explain everyday occurrences in individuals lives that did not really have a simple explanation at the time due to lack of knowledge. Therefore, these stories usually involved the acts of deities to explain the different unknown events in the world such as the moon dissapearing, shooting stars, volcanoes, hurricanes, etc.

The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.

Answers

Answer: small groups of individuals leave their home population and establish new settlements, mating only among themselves.

Explanation:

The founder effect is what happens when a small group of individuals leave their home population in order to establish new settlements. They will then mate only amongst themselves and colonize the area without mixing with the natives.

As a result of the founder effect, there is less genetic variation in the new population than in the home one because the smaller number of individuals who left would not possibly be able to carry all the genes in the home population. The only genes that would be passed on are those of the small individuals.

Determine if the process is an example of anabolism or catabolism.​ French fries are digested in the intestine, breaking them into smaller molecules A body builder exercises to build muscles through protein synthesis A child eats a milkshake, which provides her with energy Process Catabolism

Answers

Answer:

--> French fries are digested in the intestine, breaking them into smaller molecules.(Catabolic process)

--> A body builder exercises to build muscles through protein synthesis. (Anabolic process)

--> A child eats a milkshake, which provides her with energy (catabolic process).

Explanation:

CATABOLISM is the process by which living organisms break down large or complex molecules into smaller molecules with the release of energy for their own use. Foods that we consume contains different nutrients which includes carbohydrates, fats &oil, and protein. These nutrients are made available for our body cell use and maintenance through the process of catabolism. Through catabolic processes, these nutrients are broken down into its smaller constituents with the release of energy which is used immediately to power molecular machines that support cell, tissue, and organ function. The following are examples of a catabolic process as it involves breakdown:

--> French fries are digested in the intestine, breaking them into smaller molecules and

--> A child eats a milkshake, which provides her with energy

In contrast, anabolic process involves the building up larger molecules from smaller ones. It uses ATP molecules generated by catabolic reactions as a form of energy to create new molecules that form new cells and tissues, and revitalize organs. For example, muscles can be built from the synthesis of proteins. This is also called anabolic training.

French fries are digested in the intestine, breaking them into smaller molecules - Catabolic process

A body builder exercises to build muscles through protein synthesis - Anabolic process

A child eats a milkshake, which provides her with energy - Catabolic process

Catabolism can be defined as the break down of larger molecules into smaller ones in a series of metabolic pathways of which the energy produced undergoes oxidation and then is released or it is used in another reaction. Digestion is an example of a catabolic process i.e. French fries are digested in the intestine, breaking them into smaller molecules. A child eating a milkshake, which provides her with energy (energy is produced) is a catabolic process.

Anabolism involves the build up of molecules from smaller molecules usually needed for bodily functions. Protein synthesis is an anabolic process (buildup from small amino acids to large proteins. A body builder exercises to build muscles through protein synthesis is an example of anabolism

There have been several mass extinctions in the planet's history, such as the extinction of the dinosaurs, but the current mass extinction is different. Greater numbers of species are now going extinct faster than ever before. Also unique to the current mass extinction is the cause. What is causing the current mass extinction

Answers

Answer:

    There are several actions that not only humans have done to cause mass extinction. There are things such as poaching which is simply killing large and rare animals for horns, fur, meat, tusks, etc. These parts can be sold for money or resources. When one type of animal has characteristics of parts that give the poacher lots of wealth, herds or single animals can be tracked down and killed. The number of these animals dwindle down, and if nothing is done to help the animal, it goes extinct.

   But things such as nature itself that can cause extinction where humans can do nothing about. For instance, a frog species called "Splendid Poison Frog " has gone extinct for a certain type of fungus that wiped the entire species out, where we can't do anything about.

There are many results on mass extinction, but these two are some that are caused.

For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.

Answers

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

 

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.  

In this experiment,

The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variableSodium  bicarbonate  solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.

The trait of living things that's depicted by a virus that mutates is that it evolves.

The difference between a virus and a unicellular organism is that Unicellular organisms have a cell membrane made from a lipid bilayer; viruses have a protein coat.

The lytic cycle is when a virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

The difference between the lysogenic cycle and the lytic cycles is that the host cell is destroyed during the lytic cycle.

The reason why doctors recommend people, especially the elderly and those with weak immune systems, get the flu vaccine every year is because they should get the flu vaccine because viruses mutate.

It should be noted that when a virus mutates, it shows its ability to evolve. In such a case, there's transformation and development regarding the virus.

People are advised to get the flu vaccine every year because viruses mutate. In this case, getting the flu vaccine will help protect the person from the virus.

Getting a flu vaccine is vital especially for the people that have a low immune system as well as for the older people who are already weak.

true it produces ATP that can be directly used by cells

true it does not directly require oxygen to operate

false it produces more ATP than any of the other respiration reactions

Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

What is ATP?

ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.

Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.

Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

2.1explain the body's hormonal response to dehydration​

Answers

Answer:

Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.

The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.

What is dehydration?

Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.

The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration.  It makes the kidney to filter less water.

Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.
