Answer:
B
Explanation:
I believe it's B because desertification is the process of land being turned into deserts due to many factors like animal grazing.
Desertification means the process of turning arable land into deserts, which is the second option. Desertification is a process in which agricultural land is affected the most, resulting in the land having fewer nutrients.
What is desertification?Desertification is a process in which arable land is affected, and as a result, crop production is reduced. Desertification is the result of many factors, such as climate change, rapid urbanization, population growth, global warming, etc. The less water, nutrients, and microbes there are in the soil, the more likely it is that the land will become a desert.
Microbes in the soil become extinct as a result of climate change, causing crop patterns to shift and more land to become desert. Global warming causes temperatures to rise and many species to become extinct, exacerbating the problem.
Hence, desertification means the process of turning arable land into deserts, which is the second option (b).

Some fruit flies have orange eyes and others have red eyes.
If two orange-eyed fruit flies are crossed, their offspring always have orange eyes.
If two red-eyed fruit flies are crossed, their offspring sometimes include both orange-eyed and red-eyed flies.
What can be concluded from these observations?
Answer:
not 100% sure but
Explanation:
might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.
again not 100% sure

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?
1.A deletion occurred so all of the amino acids added after the mutation may be wrong.
2.An insertion occurred so all of the amino acids added after the mutation may be wrong.
3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.
4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.
Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

Answer:
'Scanning electron microscope' is the correct answer because two types of electron microscope are used to study plant cells in culture, the transmission (TEM) and scanning (sem) electron microscopes. with the TEM, the electron beam penetrates thin slices of biological material and permits the study of internal features of cells and organelles

Evolution is defined as a change in allele frequencies in a population over time.How is the relationship between malaria and sickle cell n example of human evolution?
Answer:
Dramatic evolution within human genome may have been caused by malaria parasite. A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study.
People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.05-May-2011
Explanation:
An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation's damaging effects might be offset — in a biological way of thinking — by its potential benefits.

ASAP What occurs after the homologous pairs are separated?
A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.
