What features of eukaryotes provide additional opportunities for the regulation of gene expression compared to bacteria? Select all that apply. Select all that apply. interaction with external environment transcription and translation are coupled processes separated processes of transcription and translation presence of chromatin opportunity for posttranscriptional and pre-translational regulation activation of all genes in genome
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.in developing countries, which of the following is predicted to happen to both population and demand for meat and milk?
A. it will double by 2050
B. it will decrease by 2050
C. it will stay the same in 2050
D. it will increase slightly by 2050

Mendel was a careful researcher who studied the inheritance of certain traits in garden peas. What are some of the research practices Mendel used? Choose all that apply.
A. He crossed true-breeding pea plants.
B. He allowed eggs to be fertilized only by self-pollination.
C. He analyzed his data mathematically.
D. He controlled variables by studying one or two traits at a time.
The research practices Mendel used is applies including A, B and C.
What is Mendel's experiment?
Mendel studied inheritance in peas (Pisum sativum). He chose peas because pea plant are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and can usually self-pollinate.
Mendel studied the inheritance of 7 traits in pea plants including height, flower color, seed color, and seed shape and each trait had 2 forms. He identified pure-breeding pea plants that consistently showed 1 form of a trait after generations of self-pollination.
Mendel proposed a theory of inheritance, based upon the observed data during his experiments, and a mathematical analysis of his results,
Thus, from above, the correct options include A, B and C whereas D doesnt apply because Mendel studied 7 traits at a time.

The purpose of mitosis is to ___, while the purpose of meiosis is to ____.
a) make new cells, and only germ-line cells do it;
b) make eggs or sperm, and all the body cells do it make eggs or sperm, and only germ-line cells do it;
c) make new cells, and all body cells do it make eggs or sperm, and only somatic cells do it;
d) make new cells, and all body cells do it make new cells, and all body cells do it;
e) make eggs or sperm, and only germ-line cells do it
Answer:
A) make new cells(somatic cells)and only germ-line cells do it(meiosis)
Explanation:
Meiosis is the process through which germ cells that produce gametes such as sperm and eggs are formed. It is an equatorial division that involves the parental cell dividing into daughter cells each containing similar genetic material as the parents cell and this can be passed on to successive generation.
While Somatic cells are cells that form the building blocks of the body, they are the actively divided body part and only divide by mitosis.
Meiosis produces germ cells while mitosis produces somatic cells.
Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form. Liver phosphorylase a concentration decreases when glucose enters the blood. As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. Liver phosphorylase a is regulated by AMP, adenosine monophosphate. When PP1 is bound to phosphorylase a, both PP1 and phosphorylase a are active.
Answer:
Liver phosphorylase a concentration decreases when glucose enters the blood.
The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form
As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form
Explanation:
Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.
You have two fly lines carrying two different alleles of white, called wco (coral) and wch (cherry). Coral and cherry are in the same complementation group and exhibit NO complementation. Which is true regarding recombination between these alleles in a cross:
a. recombination is never observed because coral and cherry are in the same complementation group
b. recombination is impossible because they are in the same gene (white)
c. recombination is never observed because coral and cherry display the same phenotype
d. recombination is possible and can generate a wild-type allele and a double mutant allele
Answer:
Recombination is possible and can generate a wild-type allele and a double mutant allele ( D )
Explanation:
The true statement regarding the recombination between the alleles is : Recombination is possible and can generate a wild-type allele and a double mutant allele.
The recombination process involves the breaking and recombination of pieces of DNA in order to produce new alleles. this recombination ( crossover ) results to the offspring possessing different combination of genes ( wild -type allele and double mutant allele ). hence option D is the correct answer.
Osmotic pressure is: the pressure required to stop the flow of solvent from a region of high solute concentration to a region of low solute concentration. the pressure required to stop the rupture of the semipermeable membrane. the pressure required to reverse the flow of solvent through a semipermeable membrane during osmosis. the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration. None of these
Answer:
the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration.
Explanation:
Osmosis is the movement of water (solvent molecule) from a region of low solute concentration to a region of high solute concentration via a semipermeable membrane.
Osmotic pressure is the pressure (force) applied to a given solvent in order to prevent it's movement via osmosis across a semipermeable membrane. Since, osmotic pressure is the pressure required to stop osmotic process, then it can be further defined as follows:
Osmotic pressure is the pressure required to stop the flow of solvent from a region of low solute concentration through a semipermeable membrane into a region of high solute concentration.

Cytokinesis in animal cells is accomplished by constriction of the cell along the plane of cell division (formation of a cleavage furrow).
a. True
b. False
Answer:
A) True
Explanation:
Cytokinesis can be regarded as a physical process which brings about cell division, that enables division of cytoplasm of parental cell and turn it two daughter cells. It can take place with both mitosis and meiosis concurrently which are nuclear division that occurs in animal cells. Cytokinesis In animal cells can be achieved as a result of of formation of cleavage furrow by a contractile ring of microtubules of the cell, which brings about division of cell membrane to half.
The microtubules which is utilized during cytokinesis are ones that are been generated at early stages of division and they have a part to play in the restructuring of the new cell
In the digestive system, what part of the body precedes the large intestine?
O A. Esophagus
OB. Stomach
O C. Small intestine
O D. Mouth
In the digestive system, small intestine of the body precedes the large intestine. Therefore, option (C) is correct.
What is small intestine?The small intestine is a long, narrow tube-like organ that is part of the digestive system in humans and other animals. It is located in the abdominal cavity between the stomach and the large intestine, and is approximately 6 meters (20 feet) long in adult humans.
The primary function of the small intestine is to digest and absorb nutrients from food. It accomplishes this through the action of enzymes and other digestive secretions produced by the pancreas and liver, as well as through the action of tiny finger-like projections called villi and microvilli that line the intestinal walls. These structures increase the surface area of the small intestine, allowing for efficient absorption of nutrients into the bloodstream.
The small intestine plays a critical role in maintaining overall health and well-being by ensuring that the body receives the necessary nutrients to support its various functions.
