Answer:

Many parts of the cardiovascular system (including the heart) are influenced by gravity. On Earth, for example, the veins in our legs work against gravity to get blood back to the heart. Without gravity, however, the heart and blood vessels change – and the longer the flight, the more severe the changes.

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.

Answer:  the answer to this is D because these rays can show you where the fire is located even if it is enveloped in a cloud of gray and black smoke that prevents you from seeing it.

Explanation:

The electromagnetic waves be used to fight a forest fire should be option D. Infrared images can show hot spots as red areas.

The gamma-ray images should represent hot spots just like the radioactive areas.

The ultraviolet images represent the hot spots just like the fluorescent areas.

Also, these rays should represent where the fire is located also the black smoke prevent you.

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.

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.

Answer: I would say answer C

Explanation:

The statement which is true about these environmental changes is that the Environmental change 1 is reduced space and environmental change 2 is disease. Thus, the correct option will be C.

Environmental change can be defined as a change or any disturbance of the environment which is most often caused by human influences and the natural ecological processes. Environmental changes are the effect of changes which include various factors, such as natural disasters, human interferences, or the animal interaction.

The statement which is true about these environmental changes is that the Environmental change 1 is reduced space and environmental change 2 is disease. This is because, in environmental change 1 the different species compete for resources and in environmental change 2 the species are affected with infectious virus.

Therefore, the correct option will be C.

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.

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:

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.

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:

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.

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.

Use the Weather probeto measure the land-air and ocean-air temperatures. What are these temperatures at this time? 29.1 degrees and 22.2 degrees, respectively. C.

Explanation:

By using the Weather probe to measure the land-air and ocean-air temperatures. It is found that the temperature of land air is found be 29.1°C and the temperature of ocean air is found to be 22.2°C.

A weather probe may be defined as an observation post where weather conditions and meteorological data are considerably observed and recorded under controlled conditions. While weather governs the state of the air and atmosphere at a particular time and place.

According to the context of this question, a weather probe determines a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate.
