These theories have been used to explain the transmission of genes that promote homosexuality.
According to these theories, something happens to our genetic material when we are born or give birth to children which makes people experience attraction to the same sex. In fertile females theory, if there is a particular gene found on the x chromosome in men, they are likely to be gay; but if it's found in women, they will be more fertile than usual.
The percentage of hemoglobin that will be saturated when the PO2 is 20 mmHg is 20%.
<h3>Why is it beneficial for the hemoglobin near these tissues to NOT pick up oxygen?</h3>
It is recommended that the tissues do not absorb oxygen at this point because the affinity of hemoglobin for oxygen will be low since the medium will be acid due to the amount of hydrogen ions and carbon dioxide, situation that occurs in tissues where oxygen is metabolized quickly. Therefore, then there will be no absorption of oxygen from these tissues, but rather it will occur in oxygenated tissues such as the lungs. This is an effect called the 'Bohr effect' and allows oxygen to be released where it is most needed.
And the percentage of oxygen saturation will be 20% according to the hemoglobin saturation curve.

Answer:
The levels of inputs and outputs will be negatively affected
Please find the detailed explanation below
Explanation:
The electron transport chain consists of a series of molecules that transfers electrons to one another in a group called COMPLEXES. The major aim of the ETC is to build a proton gradient needed for the synthesis of ATP. The first step in the ETC is as follows:
The process of ETC starts when two electron carriers/donors viz: NADH and FADH2 transfers their electrons to COMPLEX I. If this does not occur, the ETC cannot function. Hence, in a case where cells were treated with a chemical that inhibits the first step of the electron transport chain, the input and output (ATP) will be greatly affected in the sense that other inputs will not be used or the output will not be produced.
Answer:
The primary difference between repressible and inducible systems is the result that occurs when the effector molecule binds to the repressor. ... Thus, for the trp operon , the addition of tryptophan (the effector molecule) to the E. coli environment shuts off the system because the repressors binds at the operator.

<h2><u>Science</u></h2>
Science is the study of the natural world or physical universe.It is the knowledge of anything that can be verified by experiments.Science is organised into different fields of study. These fields are physics, chemistry, biology, geography, Earth science, geology, resource science, mathematics, nutrition, astronomy, biotechnology, engineering, computer and information technology.

<h2><u>Scientists</u></h2>
Scientists are people who study science.They use observation, experimentation and theory to collect facts and learn about a subject.They perform experiments and record their results which form the basis of science and the scientific knowledge around us.Scientists gain knowledge in the different fields of science by using specific ways and methods.
<h2><u>Laboratory</u></h2>
A laboratory or lab is a building or a part of building fitted with scientific equipment.
Scientists do experiments in labs.
Labs in schools and colleges are the classrooms where practical learning and demonstrations take place
