Where in the cell would you expect to find the greatest activity of the pyruvate dehydrogenase complex?
Answer:
Mithochondria
Explanation:
In eukaryotes, the pyruvate dehydrogenase complex, like the enzymes for citric acid cycle and oxidation of fatty acids, is located in the mitochondrion, where is associated with the surface of the inner membrane facing the matrix.
In the cell, mitochondria are the place where it expects to find the greatest activity of the pyruvate dehydrogenase complex.
What is the pyruvate dehydrogenase complex?The three-enzyme complex known as the pyruvate dehydrogenase complex (PDC) is responsible for pyruvate carbonylation, which converts pyruvate to acetyl-CoA.
This complex connects the glycolysis metabolic pathway to the citric acid cycle by allowing acetyl-CoA to be used to perform cellular respiration.
The enzyme pyruvate dehydrogenase catalyzes the reaction between pyruvate and a lipoamide, which yields acetylated dihydrolipoamide and carbon dioxide. The process requires the coenzyme thiamine pyrophosphate.
Therefore, the site where you find the greatest activity of the pyruvate dehydrogenase complex is mitochondria.

suggest a reason why termites have no eyes
Answer:
the pests have antennae covered with moisture-sensing receptors
Explanation:
Answer:
Many species of termites need to find areas of vegetation with plenty of moisture to survive. To get around their lack of vision, the pests have antennae covered with moisture-sensing receptors.They also have eyes but their wings do not develop further. These develop into the neotenics (see below), which are one of the reproductive types and have the ability to produce eggs in the colony in certain situations

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?
The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.
First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.
In this case, when a flatworm is cut in half, we can see the following events happen:
At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

Organisms require a variety of chemical nutrients, such as ______, which are components of proteins, nucleic acids, and ATP.
Organisms require a variety of chemical nutrients, such as NITROGENOUS, which are components of proteins, nucleic acids, and ATP. It is an essential element for life.
Nucleic acids, either DNA or RNA, contain nitrogen in the nitrogen bases of their nucleotides (i.e., Adenine, Guanine, Cytosine and Thymine, Uracil).
Adenosine triphosphate (ATP), the energy coin of the cell, contains nitrogen in its Thymine nitrogen base.
Finally, proteins are made of amino acids, whose building blocks are carbon, hydrogen, oxygen and nitrogen atoms.

Answer:
Genes
Explanation:
Hereditary information is stored in genes, which are found on each cell's chromosomes. Each gene contains a single piece of information. An individual's inherited trait can be determined by one or more genes, and a single gene can influence more than one trait. There are thousands of different genes in a human cell.

Which statement correctly describes mitotic cell division?
Answer:
Explanation:
“Although part of your question is missing, you might be referring to this full question:
Which of the following correctly describes how mitosis and meiosis are similar?
A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.
B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.
C. Both mitosis and meiosis produce diploid daughter cells.
D. Both mitosis and meiosis produce genetically identical daughter cells.”
The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.
Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:
During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part
Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells
Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

I think its B? Can someone explain it to me tho
Explanation:
I think it should be C because increase in temperature increases molecular motion. Therefore the speed of the moving molecules of both enzymes as well as the substrate will be accelerated. This
will enhance the colliding probability for both enzyme active sites and substrate molecules and more collisions occur between the enzyme active sites and substrate molecules generate greater chances for the reaction to occur. This can continue up to a certain point, after which there is a rapid decline in enzyme activity. This point is referred to
as optimum temperature. When the temperature increases beyond the optimum temperature, the hydrogen bonds, ionic bonds and other weak chemical bonds of enzyme active sites may be disrupted.
This will result a change in the shape of the active site of enzyme which will alter the complementary nature of the active site of enzyme molecules. Therefore, the
complementary binding of enzyme active sites and substrate molecules will be prevented. The above event is called as denaturation of enzyme molecules.
Therefore the rate of enzyme catalyzed reaction or in this case, photosynthesis will start to decline when the temperature increases beyond the optimum temperature and stops completely at certain
temperature, although rate of collision will keep on increasing.
