Because there are 23 chromosomes in the haploid cells. Chromosomes from each haploid cell (sperm/egg) come together to from a diploid cell, meaning that the 23 chromosomes from the sperm have intermixed with 23 chromosomes in haploid cells of the egg so this is you answer hope this helped

Describe three clean coal technologies and how they can mitigate the environmental impacts of coal. Explain how they work and pr
Andrej [43]

Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:  

1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.  

2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.  

3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.  

An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.

You are an evolutionary entomologist. You have observed beetles that can raise their abdomens and give off a defensive chemical
bagirrra123 [75]

Answer:

mimicry

Explanation:

Mimicry -

It is the resemblance in between two organisms of different species or may be of the same species .

The main reason for mimicry is the protection of the species from the predators .

From the question , the beetles in the second case mimic the characteristic of the first beetle , by raising their abdomen , just top protect them selves .

Hence , the correct term for the given question is - mimicry .

What would decrease the amount of oxygen discharged by hemoglobin to peripheral tissues?
Marina CMI [18]

The following factors will decrease the amount of oxygen discharged by hemoglobin to peripheral tissues.

A) decreased temperature

B) increased pH

C) decreased amounts of DPG

D) increased tissue PO2

How oxygen is being transported?

About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.
