Answer:
Explanation:
A point (substition) mutation is when one base is substituted for another. A silent mutation is a type of point mutation. It is when one base is substituted for another but the amino acid does not change. The new codon that is made from the substitution still codes for the same amino acid as the original codon was suppose to. The protein made is still functional. A missense mutation is also a type of point mutation. It is when a one base is substituted for another causing the amino acid to change. It creates a nonfunctional, truncated protein. A nonsense mutation is the last kind of point mutation. It is when one base is substituted for another and the new codon made codes for a STOP amino acid. This makes a nonfunctional, truncated protein. A frame shift mutation is when the entire reading frame if the DNA sequence is changed. The two types of frame shift mutations are deletion and insertion. Deletion is when one nucleotide is taken away, or deleted from the DNA sequence. This will make a nonfunctional protein. Insertion is when a nucleotide is added to the DNA sequence. It makes a nonfunctional protein. Missense and nonsense mutations can also be frameshift mutations, but never silent. A chromosomal mutation occurs when the sister chromatids or homologous chromosomes fail to separate. Duplication is a type of chromosomal mutation where one chromosome have two copies of a gene or genes and the other no copies.
at 21 days into development, the cells are the shape of a flat disk but will fold into a ____.
A.sphere
B.box
C.pyramid
D. tube
Answer:
Animal cells are primarily in spheres or oblong shapes such as ovals. Plant cells are usually tubes or squares/rectangles. I have no idea what cells go into pyramids.

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:
evaporation will reduceclouds won't formprecipitation would dropfreezing will occurLearn more here:

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.

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

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.
