Answer: The answer is cT bringing warm dry conditions
Explanation: Because, What type of weather does an air mass usually bring?
They can bring anything from tropical warm and humid days to arctic cold depending on the type of air mass. Fronts form the boundaries of air masses with differing properties. The most severe weather usually occurs when dry-cold continental polar air clashes with warm-humid maritime tropical air.

Null mutations in ________ genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo.
a. gap.
b. pair-rule.
c. coordinate.
d. homeotic.
Answers
Answer: c. coordinate.
Explanation:
Coordinate genes are those genes which are responsible for the development of major coordinate axes in the embryo. These axis include the anterior posterior axis and dorsal and ventral axis. These genes are responsible for the development of front, rear, top and bottom portions of the embryo. A null mutation restricts the transcription and translation processes in a gene thus when the RNA is not produced then no functional protein is expected. If the null mutations occur in the coordinate genes than it will effect the embryonic development. This will interfere in the formation of anterior and posterior poles of the embryo.
Null mutations in coordinate genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo (Option c).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.A null mutation is a type of mutation that prevents RNA transcription from a given gene or protein translation.In consequence, a null mutation is a loss of function mutation that leads to the faulty production of the associated gene product (i.e., the protein).In conclusion, null mutations in coordinate genes would be expected to result in the failure to establish the anterior-posterior poles of an embryo (Option c).

7. Once anaerobic respiration takes place, are the effects permanent? Why or why not?
If a tutor can give me the answer that would be very helpful
Answers
Once anaerobic respiration takes place, the effect is not permanent. When enough oxygen is available, the cell uses the oxygen to oxidise the glucose.
What is anaerobic respiration?In anaerobic respiration, oxygen is not used for the oxidation of glucose, and as a result, very little energy is produced. Glucose undergoes glycolysis and forms pyruvate. Without the presence of oxygen, lactic acid and ethanol are formed from the glucose.
When a person runs too fast, he can't breathe properly, and muscle cells don't get enough oxygen. Due to this, glucose undergoes anaerobic respiration and forms lactic acid. As less energy is produced, more is required by the cell, and a muscle cramp takes place.
When the person gets enough oxygen, this process will reverse as the cells get enough oxygen to completely oxidise the glucose. Due to the lactic acid formation in muscles, the blood pH declines, making the blood acidic.
Hence, when enough oxygen is available, this effect of anaerobic respiration will reverse.

Answers
Answer:
1. Gene drive.
2. Consensus.
3. Clones.
4. Coverage.
5. Pharmacogenomics.
6. Sanger sequencing.
7. Sequence assembly.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Deoxyribonucleic acid (DNA) is an organic complex-molecular structure found in all living organisms. It comprises of genes and is essentially the foundation block of all living organisms such as humans, animals and plants.
The human somatic cell is made up of 46 chromosomes which are sub-divided into 22 pairs of autosomes and a pair of sex chromosomes (X and Y). An autosome is one of the numbered chromosome that is typically not a sex chromosome.
On the other hand, sex chromosomes (X and Y) are responsible for determining the gender or sex of living organisms such as humans.
The various terminologies used in the field of genetics and their respective description are matched below;
1. Gene drive: self-propagating mechanism by which a desired genetic variant can be spread through a population faster than traditional Mendelian inheritance.
2. Consensus: likely sequence of a piece of DNA.
3. Clones: replicated pieces or fragments of DNA.
4. Coverage: the number of unique reads that include a given nucleotide in the reconstructed DNA sequence.
5. Pharmacogenomics: study of how genes affect a person’s response to particular drugs.
6. Sanger sequencing: original method for determining the nucleotide sequence of DNA, also called "chain termination method."
7. Sequence assembly: aligning the sequenced fragments from a longer DNA sequence in order to reconstruct the original sequence.

So, just to give you a heads up, these do change and sometimes vary for some, however please make sure before you look into these. Thanks! Just pre-warning!
1. The two organisms that are the most closely related would be:
~A and C~2. Based on the information of percentages of DNA, the order they should go on the cladogram (from least related to most related) would be:
~B, A, C, humans~3. The evidence that would support the relationships shown on the graph between amphibians, reptiles, birds, and mammals would be:
~Mammals have more genes in common with birds than with amphibians.~4. The piece of evidence, if true, that would most likely weaken the hypothesis that humans and chimpanzees have a common ancestor to gorillas would be:
~The cells of the eye on embryos of gorillas and humans follow a similar pattern of development while chimpanzee embryos are different.~5. The similarity of the structures of the forelimbs of bats and humans are known as:
~homologies~because they result from species evolving:
~from the same common ancestor~6. The suggestion above discussing the fact "all vertebrate embryos have a tail and gill slits at some point during embryonic development" helps to suggest that:
~These species share a common ancestor.~7. The conclusion that can be made based on the statement "Fossil A is found closer to the surface compared to Fossil B." would be:
~Fossil B is most likely older than Fossil A.~8. The statement that could be used to explain the similarity of the developmental process of vertebrate embryos would be:
~All vertebrates develop a backbone that protects the spinal cord.~9. The term for the remains, imprints, or traces of living things from a previous geological age would be:
~Fossils~10. The reason some mutations, or changes in the sequence of DNA, don't have any effect on the characteristics of the organisms would be:
~The mutated sequence still codes for the same amino acid.~11. What is typically studies when analyzing not-yet-born (or unhatched) animals is:
~embryological development.12. What scientists can analyze to get a better understanding of how plants and animals evolved from a common ancestor is:
~DNA molecules~13-16. The rest of the questions are written responses, 13-15 being short answers and the last being a single 3-5 sentence response. But no fear!

Describe how the lactic acid produced in muscle cells enters the blood
Answers
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.

Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
