Answer:
Hey!
Here's why its important:-
When a foreign antigen reaches one’s blood, it stimulates the defense mechanism. On receiving unmatching blood, the antigen present in the donor's blood and the antibody present in the recipient's blood will react with each other and form a blood clot. Hence, everyone cannot receive blood from all blood groups.
Answer:
While there are more than 20 blood-type systems, ABO and Rh are the most important ones. The importance of knowing your blood type is to prevent the risk of you receiving an incompatible blood type at a time of need, such as during a blood transfusion or during surgery.
Hope it helps

Define Chromosome, gene, and chromatid. Draw a picture of a chromosome and label it. Write a brief summary of both videos (at least 5 sentences each). From the second video make sure you include a chart that shows the differences between DNA and RNA.
Answer:
i can only define the terms for you.
Explanation:
chromosome - a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
chromatid - each of the two threadlike strands into which a chromosome divides longitudinally during cell division, each containing a double helix of DNA.
gene - a distinct sequence of nucleotides that forms a part of a chromosome, the order of which determines the order of monomers in a polypeptide or nucleic acid molecule which a cell or virus that may synthesize

The purpose of DNA replication is to * make changes in base pairs in order for an organism to evolve make an exact copy of a DNA strand for bacterial reproduction to repeat patterns of DNA in order to expand the bacterial genome to transribe information to RNA in order to synthesize proteins
Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be to make an exact copy of a DNA strand for bacterial reproduction.
DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction.
Without reproduction, DNA replication would not have been necessary.

Compare the DNA Sequence and circle any single base that is different in the cow and human sequences. How many bases are different?
Complete question:
Below are two partial sequences of DNA bases (shown for only one strand of DNA) Sequence 1 is from a human and sequence 2 is from a cow. In both humans and cows, this sequence is part of a set of instructions for controlling a bodily function. In this case, the sequence contains the gene to make the protein insulin. Insulin is necessary for the uptake of sugar from the blood. Without insulin, a person cannot use digest sugars the same way others can, and they have a disease called diabetes.
1 Using the DNA sequence, make a complimentary RNA strand from both the human and the cow. Write the RNA directly below the DNA strand (remember to substitute U's for T's in RNA)
2. Use the codon table in your book to determine what amino acids are assembled to make the insulin protein in both the cow and the human.
Human DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA
Cow DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC
Analysis
1. Compare the DNA Sequence and circle any single base that is different in the cow and human sequences. How many bases are different? _____
2. Examine the amino acids produced. Highlight in yellow any amino acids that are different in the two sequences. How many are there? ______
3. Could two humans (or two cows) have some differences in their DNA sequences for insulin, yet still make the exact same insulin proteins? Explain.
4. Examine the codon chart and list all of the codons that code for the amino acid leucine. List them.

Explanation: Telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decompensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid
How is lactase an example of fitness in humans?
[tex] \\ [/tex]
Evolutionary advantages. Lactase persistence is a text-book example of natural selection in humans: it has been reported to present stronger selection pressure than any other known human gene. However, the specific reasons as to why lactase persistence confers a selective advantage "remain open to speculation".
WHAT THEY DO IN HUMAN BODY?Lactase breaks down the lactose in food so your body can absorb it. People who are lactose intolerant have unpleasant symptoms after eating or drinking milk or milk products. These symptoms include bloating, diarrhea, and gas. Lactose intolerance is not the same thing as having a food allergy to milk.
In pastoralist populations, individuals with the lactase-persistence mutations were more likely to survive, reproduce, and pass on their alleles than people without the mutations, especially in times of famine.

Describe what might happen in the water cycle if
the amount of solar energy entering the Earth
system decreased.
When the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurThe water cycle can be described as a biogeochemical cycle that depicts how water is being circulated and recycled within, above, and on the earth's surface.
A typical diagram showing a water cycle is attached below.
From the water cycle diagram, we can observe that a vital aspect of the water cycle involves the sun which supplies solar energy that heats up earth.
The solar energy entering earth makes it possible for evaporation of water as vapor which form clouds that leads to rainfall.
The solar energy is also important in melting of ice, thereby converting it to water to goes into oceans for evaporation.
The implication of having an earth system where the amount of solar energy that enters it is reduced is that:
evaporation of water will reduced, clouds will not be able to form, and we won't have enough rainfall, andice would be predominant as low solar energy that is required to melt the ice is reduced.In conclusion, when the amount of solar energy that enters the system become decreased, what may happen in the water cycle are:

why is freedom a concern for creationists?
Answer:
Freedom of Religion and Science Instruction in Public Schools" (Yale Law Journal, January 1978, 87:3:515-570), attorney Wendell R. Bird lays the constitutional foundation for demanding equal time in the public schools for "scientific creationism." Because this article is referred to so frequently by creationists, it will be necessary to analyze its main arguments in detail
If my cultures are suffering severely due to alkaloid production and accumulation in the medium. In that case, how can i overcome this problem?
Explanation:
Alkaloids are essentially natural compounds, and can mostly be used for pharmaceutical purposes. Natural habitats of different alkaloid plants have been destroyed for cultivated.
Many alkaloids are pharmacologically active and are useful as a message for several decades because a wide range of species, such as animals and bacteria, produce them.
Secondary and accumulating metabolites are related to different cell types such as epidermis endodermis pericycle phloem parenchyma, components, accompanying cells etc.
