The molecule BPG binds to the deoxy form of hemoglobin in the central cavity. Explain why that makes sense for oxygen delivery and why BPG is said to stabilize the deoxy state.
Answer:
Oxygen binds with the hemoglobin to carry the blood to different body parts through the circulatory system. The binding of the oxygen to Hb is regulated by the Bisphosphoglycerate or BPG molecule. It is bounded to the deoxy form of hemoglobin.
BPG binds with deoxy Hb in the central cavity of the four subunits which decreases the affinity to hemoglobin. The binding of BPG stabilizes T form or deoxy-Hb as the central cavity is larger in T form in comparison to the R state. R state has a low affinity to oxygen due to relatively smaller central cavity.

Moving up the food chain, the energy available to the organisms decreases due to metabolic heat. (You can add the second law of thermodynamics into it, if you want)
For example, in the rules of tens, the plants start with 100% of the energy but the fi red t level consumers gain 90% of the energy due to the fact energy transfers through heat.
Because of the change is available energy, consumers at the higher levels of the food chain are forced to hunt larger amounts of prey to sub stain themselves.

Which was Charles Darwin’s contribution to the study of biology?
He was the first person to recognize that organisms change over time.
He believed that organisms adapted through the inheritance of acquired traits.
He explained how traits are passed from parents to offspring.
He proposed that natural selection is the primary mechanism of evolution.
Answer:
d
Explanation:
Charles Darwin proposed that natural selection is the primary mechanism of evolution. The correct option is D.
What is natural selection?Natural selection is the method by which living organism populations adapt and change.
Individuals in a population are innately variable, which means they diverge in the some ways. This variation indicates that some people have traits that are better adapted to their surroundings than others.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help support life reproduce and survive are becoming more prevalent in a population over time.
Natural selection occurs when genes that confer a survival or reproductive advantage are handed down and persist in a population, whereas genes that result in lower survival or fewer offspring are becoming less common.
Thus, the correct option is A.

Which of these is an example of active transport?
A Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP.
B. Carbon dioxide molecules diffuse freely across the cell membrane.
C. Water molecules move down the concentration gradient across the cell membrane with the help of a channel protein.
D. Oxygen molecules become trapped inside the cell membrane with the help of ATP.
Answer:
a. glucose molecules move agnst the concentration gradient across the cell membrane w the help of atp
Explanation:
active transport requires energy (atp) to push a molecule agnst its concentration gradient
also glucose molecules r too large to cross without the help of transmembrane proteins
and oxygen molecules r able to get thru by simple diffusion bc they r small enough
Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP is an example of active transport.
Active transport is a biological term to refer to the movement within the cell in which some molecules move across the cell membrane. This movement requires energy from cells to move.
According to the above, when a glucose molecule moves against the concentration gradient across the cell membrane and in this movement it consumes energy (ATP) it is carrying out active transport.
According to the above, the correct answer is A. because it exemplifies active transport.

Which of the following processes is most likely to occur as a result of an
animal cell receiving a signal to initiate apoptosis?
Answer: lysosomes will release digestive enzymes into the cytosol
Explanation:
Apoptosis is one of the cellular mechanisms of cell death in a controlled manner. At the initiation of apoptosis, the lysosomes start secreting the digestive enzymes in the cytoplasm. Thus, option D is correct.
What is apoptosis?Apoptosis has been defined as programmed cell death in multicellular eukaryotes. It involves biochemical steps that involve cell shrinking, fragmentation of the nucleus, condensation of chromatin structure, decay of the mRNA, and the disintegration of the DNA.
It is a significant process in animal cells as it destroys the unwanted and harmful cancerous cells that can damage the body. They are very crucial in cancer and are initiated by the alteration in the survival signals and sudden dissociations.
The lysosomes play an important role in apoptosis as they're the specialized organs that release digestive enzymes that initiate cell death. They undergo autolysis when the signals for apoptosis are initiated.
