Answer:
C
Explanation:
This is because the mRNA is produced from the template strand of the DNA.
RNA polymerase reaches the end of a gene. Therefore, option (A) is the correct answer.
What is RNA polymerase?RNA polymerase produces mRNA from DNA during transcription. After the RNA polymerase has moved along the DNA template strand and synthesized the complementary mRNA molecule, it will eventually reach the end of the gene being transcribed.
At this point, the RNA polymerase will dissociate from the DNA template, and the newly synthesized mRNA molecule will be released into the cytoplasm for further processing. Therefore, option A is the correct.

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.
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).

The crayfish, like some other animals, can regenerate lost appendages. It can
also undergo autotomy. Investigate autotomy in crayfish. What is it? How is it
related to regeneration?
Crayfish exoskeleton is the part of the creature which shows autotomy and regeneration.
What is autotomy?Autotomy or self-amputation is the behavior of an animal shedding or discarding one or more of its own appendages, frequently as a self-defense technique to elude a predator's grasp or to distract the predator and thus allow escape.
Are Autotomy and regeneration the same mechanisms?No. Autotomy and regeneration are different processes however they are similar:
Certain living organisms like crayfish exhibit two processes: autotomy and regeneration.The primary distinction between autotomy and regeneration is that during autotomy, body parts are eliminated or shed from the body, but during regeneration, body parts are replaced or formed into a new creature or the amputated body part is regrownHow does crayfish undergo autotomy and regeneration?Crayfish belong to the class of crustacenas which regularly shed their exoskeleton through autotomy and regrow a new one through regeneration.the exoskeleton is rigid and hence does not grow along the size of the creature which allows the creature to shed it off. this process is known as MOLTING.Crayfish molt because as their size grows, they must shed their hard exoskeletons and grow new, larger ones. A crayfish molts six to ten times throughout its first year of existence.Molting normally takes only a few minutes. On the back side, the crawfish's brittle exoskeleton breaks between the carapace (head) and abdomen (tail), and the crawfish normally retreats by tail flipping.hence autotomy and regeneration go along each other in crayfish.

a. Many plants and animals are susceptible to slight changes in their local environments.
b. All answer choices are correct. Global warming could have significant effects on agriculture in the United States, upon which many American rely for income.
c. We can observe evidence that atmospheric carbon dioxide has increased over the past 150 years.
d. Through measurements and observations, we know that carbon dioxide levels and temperature fluctuations are directly correlated, even in prehistoric times.
Answer: The correct statement used in response to the suspicions should contain all the statements, therefore all answer choices are correct. (a, b, c, and d).
Explanation:
Global warming is an environmental situation in which there is an abnormal rise in temperature around the world due to increase in carbondioxide and other greenhouse gases such as carbon monoxide,chlorofluorocarbons, nitrogen oxides and lead.
The consequences that may emerge due to the global warming includes'
--> Reduction in biodiversity: atmospheric changes in the environment can cause mass extinction of plants and animal species that cannot migrate to new areas. Therefore option A is correct.
--> change in food production: Current climate models project 10 - 70% decline in the global yield of key food crop and a loss in current crop land area of which United States is not an exception. Therefore option B is correct.
--> Increase in atmospheric carbondioxide: this is as a result of Increased dependency on fossil fuels for energy production. Option C is correct.
--> Greenhouse effect: the unabsorbed carbondioxide becomes traped in the upper atmosphere preventing the radiation of solar energy back into the space. This leads to an increase in the global temperature which is called greenhouse effect. Therefore option D is correct.

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.

A scientist is attempting to build a cladogram that shows the evolutionary closeness of three organisms in relation to humans.
After doing DNA analysis, they determine that the organisms share the following percentages of DNA:
Organism A and humans share 85% of their DNA.
Organism B and humans share 80% of their DNA.
Organism C and humans share 90% of their DNA,
Based on this information, which order should they go on the cladogram (from least related to most related)?
(1 point)
O A, B, C, humans
OB, A, C, humans
o C, B, A, humans
OC, A, B, humans
B, A, C, Humans is the correct answer
Heyo! ;D
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! These are rather easy ones to do by yourself. Or, if you really need help, I found a lot of really helpful responses on here. Anyways, good luck!

Describe how the lactic acid produced in muscle cells enters the blood
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.
