Which features of alveoli enable them to exchange gases efficiently? (Select all that apply.)
A. thin walls
B. surrounded by blood vessels
C. small numbers of them in each lung
D. large surface area
Do not scam me using links or attachments (except photos of the answer) or answer this by saying a simple yes or no because that also scams me.
Answer:
the answer is a i hope this helps
Explanation:
The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the
Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.
What are Alveoli?These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.
Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.
Therefore, the larger surface area, presence of thin wall, which is only one cell thick, and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.

Provide an example of how a genetic mutation could be positive, then explain how that mutation could cause a change in a population over time.
Answer: Some mutations happen during cell division, when DNA gets duplicated. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.

What happens to carbon in the process of photosynthesis?
Answer:
The plant uses sunlight as energy to perform this chemical reaction. Photosynthesis separates carbon dioxide and water known as CO2 and H2O, respectively into their individual molecules and combines them into new products. It also creates C6H12O6, a substance similar to glucose, that feeds the plant.

Genetic recombination would be most closely associated with which process in disease-causing microorganisms?
A.binary fission in fungi
B.sexual reproduction in fungi
C.spore formation in bacteria
D.viral replication in host cells
Genetic recombination is most closely associated with: Choice D: Viral replication in host cells
Definition:
Genetic recombination (otherwise termed genetic reshuffling) is simply the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
In retroviruses, recombination actually occurs at the point during replication when the retrovirus genome is in a DNA form and takes place by the same break-rejoin technique as in cells and DNA viruses.
Recombination can occur both between two related retroviruses and between the retrovirus DNA and the host DNA.

Individuals with the recessive trait of night blindness (genotype nn) have difficulty seeing in low light. The pedigree shows the inheritance of night blindness in a certain family.Which of these are possible genotypes of the parental generation? Refer to the figure below and match the angle with the correct measurement in degrees.
Answer:
Cool
Explanation:
The possible genotypes of the parental generation are as follows :
Male : Night Blindness Female : Normal What is Genotype ?Genotype is the collection of the the two alleles that makes up the gene inherited by an offspring from its parents.
Given that only one of the males of the first generation suffers from Night blindness, He inherited the Night blindness from the parental generation. therefore the male from the parental generation is a carrier of the Night blindness allele while the Female is not a carrier.
Hence we can conclude that The possible genotypes of the parental generation are Male : Night Blindness and Female : Normal.
