Answer:
separated processes of transcription and translation presence of chromatin opportunity for posttranscriptional and pre-translational regulationExplanation:
Since there is no nucleus surrounding the genetic material in prokaryote cells, the transcription and translation processes occur simultaneously. Transcription stops when a protein is not necessary. So the control of protein synthesis is regulated by transcription and not translation. Once the transcription is on, all the following steps must follow it.
Transcription is the process that controls the genic expression in bacteria.
Eukaryotes do possess a nuclear membrane that separates the genetic material from the rest of the cell. The transcription process occurs inside the nucleus membrane, while the translation process occurs outside. In the cytoplasm occur the translation process and protein synthesis. Genic regulation can happen in any of these processes in different regions of the cells.
In eukaryotes, the regulation of the genic expression control might happen at different levels:
Epigenetic level: When DNA molecules open and nucleosomes separate to join the transcriptional factorsTranscription level: When the messenger RNA is being transcriptedPost-transcription level: When mRNA goes to the cytoplasm Translation level: During the protein elongationPost-translation level: Once the protein synthesis is over.If HH crossed with Hh.

Explanation: Hope this helps!
There are more than 300,000 species of plants that have been identified thus far in the world today; many new species are being discovered each year. In addition to providing most of the oxygen for land animals, plants do many other things for us. you will research the Internet and use reliable and credible scientific websites to investigate a specific plant species and choose a way (other than providing oxygen) that plants are useful to humans. [NOTE: Hot topic plants like Marijuana and Opium are off limits and cannot be discussed.]

Answer and Explanation:
We can mention the advantages of the plants of the Fabaceae family, also known as legumes, such as beans, soybeans, peanuts and peas. First, we must mention how these plants have high nutritional values providing high levels of iron and nitrogen that are essential elements for human health. However, a benefit that these planats produce and that is important on a worldwide scale is the fixation of nitrogen in the soil. All living beings need nitrogen in their bodies, since nitrogen is a primary element in the composition of nucleic acids and proteins. Animals are able to ingest nitrogen from the vegetable diet, but vegetables cannot absorb nitrogen from the atmosphere or nitrogen from the soil, because they are not in molecular forms that plants can absorb. To reverse this, farmers put chemical fertilizers on the plantations, but these fertilizers pollute the environment intensely. It is in this scenario that the plants of the Fabaceae family are important. This is because these plants are able to associate with bacteria that can capture atmospheric nitrogen and place it in the soil, in the molecular form that all plants can absorb. This allows plants to have the necessary nutrients for their growth, reduces environmental pollution, decreases spending on agricultural production, promotes correct levels of nitrogen for human consumption and allows agricultural products to be healthier.
what would never be part of an mRNA strand?
Answer:
Uracil
Explanation:
Thymine would never be part of an mRNA strand.thus, option A is correct.
What is mRNA?Messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).
It was also known that there are only four nucleotides in mRNA: adenine (A), uracil (U), guanine (G), and cytosine (C). Same three nucleotide base is also present in the DNA except thymine. Thymine is replaced with uracil in case of RNA. thus option A is correct.

Explanation:
Assume that you discover a new human gene that you believe is located on the Y chromosome although not in the region (pseudoautosomal) of the Y that is homologous with part of the X chromosome. How would you map this gene with respect to the other genes on the Y chromosome
Answer:
by performing a bioinformatic analysis in order to discover Y chromosome-linked mutations associated with defective phenotypes. In this case, it is expected to discover two or more loss of function mutations located in the coding region of the target gene on the Y chromosome in different males, and then associate such mutations with altered phenotypes caused by the inactivation (loss of function) of this gene
Explanation:
The genes located on the Y chromosome exhibit a uniparental mode of inheritance (i.e., these genes are only transmitted from father to their sons). This situation makes difficult to map the target gene since recombination does not occur for genes that are only located on the Y chromosome, hampering the development of a linkage map containing this gene. In this case, it is possible to directly associate genetic mutations located at the same genomic region (locus) on the Y chromosome with a particular altered phenotype in males carrying these mutations, which can be in principle associated with the inactivation of the target gene (loss of function mutations) in these individuals.

Woodpeckers and squirrels fight for nesting rights in the same holes and spaces in trees, while the lions and cheetahs of the African savanna fight for the same antelope and gazelle prey. Which of the following statements about these relationships is accurate?
A. These are examples of competition because the organisms are fighting for resources.
B. These are examples of predation because the organisms are trying to take each other’s food and homes.
C. These are examples of predation because lions and cheetahs eat woodpeckers and squirrels.
D.These are examples of competition because no organisms are helped or harmed.
Answer:
a
Explanation:
both of the cases the organisms are fighting for a resource
A. These are examples of competition because the organisms are fighting for resources.
How Competition and predation are two different types of relationships ?Competition and predation are two different types of relationships that can exist between different organisms in an ecosystem. Competition occurs when two or more organisms are fighting for the same resources, such as food, water, or shelter.
This can occur within or between different species. In the example given in the question, woodpeckers and squirrels compete for nesting rights in the same holes and spaces in trees, while lions and cheetahs compete for the same antelope and gazelle prey.
On the other hand, predation occurs when one organism (the predator) hunts, kills, and consumes another organism (the prey). This type of relationship is often seen between carnivores and herbivores, or between animals and insects. In the example given in the question, lions and cheetahs are predators that hunt and consume antelope and gazelle prey.
It is important to note that in both competition and predation, one organism may benefit while the other is harmed.
For example, in predation, the predator benefits by getting food while the prey is harmed by losing its life. In competition, one organism may gain access to the resources while the other loses out, which can affect their ability to survive and reproduce.

elect all statements that accurately describe the structures or functions of mitochondria. Mitochondria are the sites of aerobic metabolism. Mitochondria have a permeable inner membrane and an impermeable outer membrane. Mitochondria regulate apoptosis. Mitochondrial DNA is packaged with histones. The configuration of mitochondria does not change. Mitochondria are included in the endomembrane system.
Answer:
The correct statements are -
Mitochondria are the sites of aerobic metabolism
Mitochondria regulate apoptosis.
Explanation:
Mitochondria is one of the eukaryotic cell organelles that are double membrane and plays important role in the different function of the cell. The main and major function of the mitochondria is aerobic metabolism that includes aerobic respiration where glucose converts into carbon dioxide and water with releases a high amount of energy in the form of ATP.
These also plays important role in programmed cell death or apoptosis it activates apoptosis by releasing protein by the inner and outer membrane. The inner membrane of mitochondria is impermeable and allows through transporters and outer membrane non-specifically permeable to low molecular substances. Mitochondrial DNA lacks histone protein and TFAM, an HMG-like protein involved in the process.

III. Protect the internal organs
IV. Make the eggs
I and II
II and IV
I and IV
II and III
Answer:
c
Explanation:
I and IV are the functions of the reproductive organs in animals.
What are Reproductive organs?
The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.
The fertilized egg is then transferred to your uterus, where the lining has expanded due to the regular hormones produced during your menstrual cycle (also called your reproductive cycle).
The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur. The female reproductive system also creates sex hormones that keep your menstrual cycle regular.
Therefore, I and IV are the functions of the reproductive organs in animals.

Scientists believe Polar Bears have evolved from a group of Brown Bears that became an isolated population during a time when the Earth's climate began cooling down.What are some adaptations that make Polar Bears different from Brown Bears and what do you think caused the adaptations to occur?
Answer:
One adaptation is white fur. There was probably one white cub born to a brown bear mother, and the fur helped camouflage it for safety and later, hunting. This bear would have been more successful in hunting in the arctic, so it was more likely to reproduce and pass on the white fur genes. A second adaptation is the long claws of brown bears that are used for digging through vegetation would have shortened to be safer on ice. Polar bear paws also have little sticky bumps on their paws for gripping ice.
A third adaptation is that polar bears don't hibernate in winter. In winter, there is a lot more food available to them, so they need to stay awake. A fourth adaptation is their hair is also now water repellent, because most of their food comes from the sea. A fifth adaptation is in their digestive system. Polar bears don’t digest carbohydrates as well as brown bears, because their diet has much more fat than anything else. Polar bears hunt seals and can convert the blubber into fat for their bodies to live off of when food is scarce.
