Please mark brainliest.
Respiration is the process of inhaling oxygen and exhaling carbon dioxide. Covering a glass prevents the oxygen to enter and can use to test anaerobic respiration. Thus, options 1. a and 2. b are correct.
What is anaerobic respiration?Anaerobic respiration is a process that uses electron acceptors to produce energy by breaking glucose or other sugar molecules. Unlike aerobic respiration, it lacks the use of oxygen for metabolic reactions.
This occurs in the absence of oxygen and occurs in the cytoplasm with the help of oxidizing substances like nitrate, fumarate, sulfate, etc. to produce less ATP compared to aerobic reactions of respiration.
Therefore, covering a glass prevents the entry of oxygen and can be used to observe the anaerobic respiration by some microbes.

how will photosynthesis affect oxygen levels?
(also if anyone could help me with the rest of these answers, that would be great <3)
The process of photosynthesis positively affects the level of oxygen in the ecosystem. This is because oxygen is the byproduct of the photosynthesis mechanism along with the main product known as Glucose.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis si as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, this is determined that if the rate of photosynthesis increases, the level of oxygen is positively affected which means it is also increasing. It is opposite to the process of cellular respiration which involves oxygen as a reactant.
Therefore, the process of photosynthesis positively affects the level of oxygen in the ecosystem.

Human Immunodeficiency Virus (HIV) is a virus that infects (and destroys) Helper T Cells. As a result, people who are HIV+ generally have a low number of these T Cells. How would the dramatic decrease in Helper T Cells caused by HIV affect a person’s immune response? Be specific using details from what you learned about the immune response.
Answer:
HIV invades various immune cells (e.g., CD4+ T cells and monocytes) resulting in a decline in CD4+ T cell numbers below the critical level, and loss of cell-mediated immunity − therefore, the body becomes progressively more susceptible to opportunistic infections and cancer.
HIV infects and deletes CD4+ T cells that normally coordinate the adaptive T- and B-cell response to defend against intracellular pathogens. The immune defect is immediate and profound: At the time of acute infection with an AIDS virus, typically more than half of the gut-associated CD4+ T cells are depleted, leaving a damaged immune system to contend with a life-long infection.

In mice, black color (B) is dominant to white (b). At a different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice with black fur. This gives a frosted appearance know as agouti. Expression of the recessive allele (a) results in a solid coat color. If mice that are heterozygous at both loci are crossed, ___ out of 16 will be black in color.
Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
9 B_A_ - Agouti
3 bbA_ - agouti
3 B_aa - Black
1 bbaa - white
Hence, 3 out of 16 progeny will be black in color.

How did New Zealand's early ecology affect which traits were selected for/against in the kakapo's ancestors?
Answer:
Hairy skin which helps kakapo's ancestors to live in harsh climate of New Zealand.
Explanation:
New Zealand's early ecology greatly affected the population of kakapo's ancestors because the environmental conditions for kakapo's ancestors are favourable and there is no invasive species which reduces the population of kakapo's ancestors near to extinction. The traits that were selected for the kakapo's ancestors provides ability to live and survive in the temperate and subtropical climates of New Zealand. The flightless trait in this bird is also responsible for its extinction because this bird can't run away from their predators.
Why are there many, many more craters on the "outer back" side of the moon than there are on the "inner facing" side of the moon?
Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.
Explanation:
The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.

Answer:
variation can be caused by mutation and other things
Explanation:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke
➜ Following are the causes of variations:
Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.
