Which of the following mechanisms is used to coordinate the expression of multiple, related genes in eukaryotic cells?
A) A specific combination of control elements in each gene's enhancer coordinates the simultaneous activation of the genes.
B) The genes share a single common enhancer, which allows appropriate activators to turn on their transcription at the same time.
Answer:
It's A
Explanation:
A specific combination of control elements in each genes enhancers coordinates the simultaneous activation of the genes. Its correct don't worry :)
The expression of multiple, related genes is coordinated through a single common enhancer gene that can be turned off by a single repressor, hence option b is correct.
How multiple, related genes is controlled?Multiple related genes are simultaneously turned off by a single repressor working in concert. The simultaneous activation of each gene's enhancer is regulated by a particular arrangement of regulatory elements.
In particular, there are two degrees of control over gene expression. The first way transcription is regulated is by regulating the amount of mRNA that can be generated from a given gene.
The translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.
Therefore a single activator can control, the expression of multiple related genes in eukaryotes, hence option b is correct.

how is the ruminant digestive system different than human digestive system?
background info:
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.
answer:
Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.
Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.
This is the key difference between digestion of humans and ruminants.
hope this helped
Answer:The primary difference is that ruminants have modified their stomach into multiple compartments in order to host a very vibrant and diverse community of microorganisms. Some of these microorganisms are able to digest cellulose and produce volatile fatty acids. These volatile fatty acids are used as a source of energy by the ruminant. Propionate - a volatile fatty acid, is the only volatile fatty acid used for gluconeogenesis.
The rumimal microbe community also provides other nutrients as well but is mostly known for its role in cellulose digestion.
Ruminants have also evolved the ability to bring up a small ball of feed from their rumen to their mouth. They then masticate (chew) this ball to breakdown the fibrous material. This ability is commonly referred to as “chewing their cud” or ruminating. hope this helps have a bless day❤️❤️

As fertilizer from farm fields makes its way into the Chesapeake Bay, a chemical reaction occurs between the nitrogen within the fertilizer and which element found in the water?
Answer:
Hydrogen
Explanation:
When Nitrogen is introduced into the Chesapeake Bay it combines with the Hydrogen in the water which causes a chemical reaction that creates Ammonia. This is a corrosive compound that is highly toxic and can kill an individual if enough of the gas that it creates is inhaled. The chemical compound of Ammonia is one Nitrogen atom and three Hydrogen atoms to make up the formula NH3.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce. Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
Answer:
Enteroviruses.
Explanation:
Enteroviruses is the pathogen that is responsible for causing hoof-and-mouth disease in livestock. Infection of this virus causes a vesicular eruption on the hands, feet, and oral mucosa in the livestock animals which greatly damaged the health of animals. These viruses needs a host cell to reproduce because it is a virus which is non-living outside the living cell.

a) What is the total distance traveled?
b) What is the total displacement?
c) What was the dog’s average speed?
d) What was the dog’s average velocity?
Answer:
1000 m ; 600 m east ; 8.333 m/s ` 5 m/s
Explanation:
Total distance :
(300 + 200 + 500) m = 1000 m
Total Displacement :
300 m east - 200 m west + 500 m east
100 m east + 500 m east
= 600 m east
Average speed :
Distance / time
100 m / 2 * 60 s
100 m / 120 s
= 8.333 m/s
Average velocity :
Displacement / time
600 m / 2 * 60 s
600 m / 120 s
= 5 m/s

The allele for a sixth finger is dominant and the allele for a non-sixth finger is recessive. In the human population the percentage of people with the dominant phenotype is LESS than the percentage of people with the recessive phenotype. How could you explain this?
Answer:
Explanation:
Polydactyly is having six fingers as against the 5 fingers. The Sixth fingers grows out like normal finger giving an additional finger.
Polydactyly is usually expressed in dominant form, when an individual is recessive for the traits such individual have 5 fingers.
In human, the rate of occurrence for polydactyly is low this is because it is a rare occurrence and it takes two individual who have the allele to produce an individual who will be dominant of the allele. The recessive allele is what is common to human.

In your journal, complete a PASAFE + TEAR paragraph analyzing the student writer's use of refutation to build his/her own argument.
ANSWER:
In response to the essay by Scott Russel Sanders, “the belief that movement is inherently good” (Sanders). The genre is this essay is an opinionated essay throughout the essay he haves a natural tone against Rushdie even towards the end. He claims that we should root ourselves in places rather than ideas, that we should care for the earth rather than our own selfish desires. In quoting Rushdie directly and repeating his words and syntax, Sanders not only assures the reader of his careful thoughtfulness on the issue but also states his own belief that moving does nothing to rid us of the unfortunate aspects of the humanity of which we all wish to be free. Sanders and Rushdie have agreement and disagreement quotes that they want to share with others, but maybe more to themselves. But still, there is no argument in this essay, and is still respectful. The audience is for all people, as one that we all should hold as a fundamental belief of society. How can one create a new relationship with the world when they are constantly altering their place in it? The gradual movement from agreement to complete disagreement reinforces Sander’s point and respectfully refutes Rishdie’s point consequently. Yet he is still respectful towards Rushdie and admits that even though he disagrees completely with him, Rushdie articulated his views “as eloquently as anyone” (Sanders). He finishes by asserting that we must root ourselves to a specific place in order to “pay enough head and respect to where are are” (Sanders).

Lichens (small green plants) growing on a large boulder release enzymes and other acids that slowly break the rock apart. This is an example of:Required to answer. Single choice. (1 Point) plant acids exfoliation abrasion
Answer:
plant acids
Explanation:
A lichen consists of a photosynthetic microorganism such as, for example, a photosynthetic green alga, which is surrounded by the filaments of a fungus. Moreover, chemical weathering is a gradual process where chemicals react with the minerals in the rock to form new minerals, oxidize or simply dissolve them. Lichens can lead to chemical weathering of rocks via the excretion of organic acids (e.g, oxalic acid) capable of dissolving minerals and chelating metallic cations.
