The genotype of an individual is the number of genes that the individual possess.

Using the Mendel crossing, we can see that if the parents are AB and AO one offspring will have type A blood.

If we look at the chart, we can see that the blood type A and B are both codominant and are dominant over O hence option K is correct.

the diaphragm is innervated by the __________ nerve, which allows it to contract.

Answers

The diaphragm is innervated by the phrenic nerve, which allows it to contract.

What is phrenic nerve?  

The C3-C5 spinal nerves, which are parts of the cervical plexus, give rise to the phrenic nerve, a mixed nerve. It begins in the neck and travels through the thorax vertically before terminating on the diaphragm.

The phrenic nerve is bilateral, there are some significant distinctions between the left and right counterparts in terms of its courses and interactions with surrounding structures.

The primary purpose of the phrenic nerve, which makes it an essential part of the physiology of breathing, is to deliver the full motor innervation to the diaphragm.

Diaphragm is controlled by the phrenic nerve (the large dome-shaped muscle between abdominal and chest cavities). It is necessary for breathing. Diaphragm contracts as a result of signals sent by nerve (become thicker and flatter). This motion makes room for  lungs to expand and take in air (inhalation).

Write a short description of the life cycle of a flowering plan

Answers

Answer:

Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.

Explanation:

hope it is helpful

Answer:

Explanation:

: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.

Menkes disease is caused by a defect in the ATP7A gene. The defect makes it hard for the body to properly distribute (transport) copper throughout the body. As a result, the brain and other parts of the body do not get enough copper, while it builds up in the small intestine and kidneys. Menkes syndrome causes impaired copper absorption. This results in changes in the arteries and deterioration of the brain. Menkes syndrome is rare. Most children born with Menkes syndrome have a life expectancy of < 4 years.

Carbon fixation occurs in the second stage of photosynthesis, during the light-independent reactions of the Calvin cycle. In the first step of this cycle, the enzyme Rubisco adds CO2 to the energy-rich compound ribulose 1,5-bisphosphate, ultimately producing two molecules of 3-phosphoglycerate. In a culture of green alga that is carrying out photosynthesis in the presence of CO2 in the laboratory, what would happen to the levels of ribulose 1,5-bisphosphate and 3-phosphoglycerate in the minutes after the lights were turned off and the cultures were plunged into darkness

Answers

Ribulose 1,5-biphosphate will be depleted while 3-phosphoglycerate will accumulate.

Carbon fixation

The first step of the carbon fixation during which Rubisco adds CO2 to Ribulose 1,5-biphosphate to produce 2 molecules of 3-phosphoglycerate requires energy molecules from the light reaction.

In the subsequent steps, Ribulose 1,5-biphosphate is regenerated in a step that requires energy molecules from the light reaction.

Thus, in the first few minutes of turning off the light, the available energy molecule from the light reaction will be used up to produce 3-phosphoglycerate. However, the regeneration of Ribulose 1,5-biphosphate will become impossible.

1°C increase of temperature can effect the biodiversity of the habitat in terms of number of populations and number of individuals in the population, it can either increase or decrease the population growth.

1°C increase in temperature on biodiversity can increase or decrease the population growth.

Population growth  or change in number of individuals in the population of some organisms increases or decreases with the increase in temperature. The population of certain species such as Nassuar grouperand, Queen angelfish increases with the increase in temperature while some species such as sponges and algae decreased in population with the increases in temperature. This is because some species need high temperature to grow, so even a 1°C increase in temperature increases the population while some species need low temperature to grow, so high temperature kills them and population is decreased.
