A. Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
B. Capillaries surrounding the brain have pores and are surrounded by membranes of astrocyte cells.
C. Capillaries surrounding the brain have no pores and are not surrounded by membranes of astrocyte cells.
D. Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.
The correct answer is option A.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells.
Explanation:
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because
Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.
Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells while capillaries in the periphery Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.

circulatory system summary
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.
Essential Question: Compare and contrast the structure and function of the major organelles found in plant and animal cells.
Answer: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Dihydromyricetin (DHM), a chemical found in the moyeam plant of Asia, has shown the ability to treat certain
cancers.
Which of the following answer choices best describes a possible mechanism of action for this cancer drug?
Choose 1 answer:
А
DHM decreases apoptosis in cancer cells.
DHM decreases apoptosis in normal cells.
DHM promotes apoptosis in cancer cells.
D
DHM promotes apoptosis in normal cells.
Answer:
(C) DHM promotes apoptosis in cancer cells.
Explanation:
Since some cancers are caused by a lack of apoptosis (programmed cell death), DHM treats cancer by forcing apoptosis to occur in cancer cells, stopping their growth and division.
The choice which best describes a possible mechanism of action for this cancer drug is DHM promotes apoptosis in cancer cells. The correct option is C.
What is Dihydromyricetin (DHM)?DHM is a chemical that is present in the plant, Hovenia Dulcis grow in Japan. It is a raisin plant and has several medicinal values. It is used in East Asia as a hangover medicine.
Apoptosis is a process of cell death, so if DHM promotes apoptosis in the cancerous cells, then it will reduce cancer by killing the cancer cells.
Thus, the correct option is C, DHM promotes apoptosis in cancer cells.

Which two structures are first to combine in translation?
1 and 4
3 and 4
1 and 2
2 and 3
The first two structures that combine during the process of translation are 1 and 4.
What is translation?The translation is a biological process during which the genetic codes in transcribed DNA, in the form of messenger RNA, are translated to their respective amino acids and joined together by peptide bonds to form proteins.
The steps involved in the translation process are:
mRNA binds to the small subunit of the ribosometRNA carrying methionine binds to the start codon on the mRNALarge ribosome subunit binds to complete the translation complex.In the image, mRNA is designated as 4 while tRNA is designated by 2. 1 is the ribosome while 3 is the synthesized protein.
Thus, the first two structure that binds is mRNA and tRNA. That will be 1 and 4.

Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondrion with the energy needed to join small molecules together?
During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)
A concentration gradient, a membrane protein, and hydrogen ions work together to provide a mitochondria with the energy needed to join small molecules together through ATP. The H+ ions are pumped across by membrane “pump proteins” into a space bounded by memb ranes that contain numerous amounts of hydrogen ions. Then, electrons are passed from o ne membrane-bound enzyme to another, which causes some energy to get lost during eac h transfer. This “lost energy” allows the pumping of hydrogen ions against the concentratio n gradient. After all the steps are taken, the mitochondrion will be provided with the energy needed to join small molecules together.
Which type of soil would be LEAST likely to support the growth of a rose bush?
Answer:
Roses are very adaptable and can be grown in almost any soil type given it is well drained, deep and full of humus (decayed organic matter).
However, the best soils are those of a medium to heavy loam to a minimum of 35cm, over a good clay sub-soil.
