What are Krebs cycle inputs and outputs?
Answer:
see below image:
Explanation:
inputs + their outputs listed in the image
The Krebs cycle continues when acetyl-CoA (2-carbon molecule) and oxaloacetate (4-carbon molecule) combine to form citrate (6-carbon molecule). Citrate is then converted into cis-aconitate, which is then converted into isocitrate. Following this step, one of the carbon atoms separates and is released as CO2.
What is Krebs cycle?The tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or the citric acid cycle, is the primary source of energy for cells and an essential component of aerobic respiration.
The cycle converts acetyl coenzyme A (acetyl CoA available )'s chemical energy into the reducing power of nicotinamide adenine dinucleotide (NADH).
The Krebs cycle is powered by lipids (fats) and carbohydrates, both of which produce the molecule acetyl coenzyme-A. (acetyl-CoA).
This acetyl-CoA reaction is the first in an eight-step sequence of reactions known as the Krebs cycle, which takes place entirely within the mitochondria of eukaryotic cells.
The net energy output of glycolysis through the Krebs cycle for one glucose molecule is 4 ATP, 10 NADH + H+, and 2 FADH2.
Thus, these are the chief inputs and outputs of Krebs cycle.

What is the purpose of DNA structure made of nucleotides
Answer:
DNA is made up of molecules called nucleotides.
Its unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA splits down the middle and becomes two single strands. These single strands serve as templates for building two new DNA molecules - each a replica of the original DNA molecule.

What is the relationship between undisturbed sedimentary rock layers and fossils?
Fossils only can be found in the youngest sedimentary rock layers.
Older fossils are found in deeper layers of sedimentary rock.
More recent fossils are found in the deepest of the rock layers.
Answer:
Older fossils are found in deeper layers of sedimentary rock.
Explanation:
The relationship between undisturbed sedimentary rock layers and fossils is that older fossils are found in deeper layers of sedimentary rocks.
This is one of the premise of the law of superposition and principle of fossil and fauna succession.
An undisturbed sequence is one in which the sedimentary layers have been arranged sequentially. The oldest is at the bottom and the youngest on top. Also, fossils grade in this manner too. The oldest fossils will be in the oldest bed which is the deepest layer. The youngest bed will contain the youngest fossils in like manner too.Large deposits of Rock Gypsum and Rock salt have been found in Upstate NY. What does this tell you about the environment of Upstate NY in the past?
Answer: There must have been a body of water there previously, maybe prehistorically.
Explanation: Gypsum forms when the right materials in a body of water come together and water evaporates quickly.
Gypsum is an evaporite, which means its crystals form during the evaporation of water. Gypsum forms whenever evaporation crystallizes the necessary minerals. In the case of "desert roses" gypsum crystals found around the world in arid sites, formation occurs with evaporation as the level of the water table changes. Gypsum can also be formed diagenetically by oxidation. This chemical reaction occurs when oxidation of existing sediments causes gypsum to form and replace other minerals in the sediments.
Huge gypsum deposits called beds were formed when ancient tropic seas became concentrated through evaporation. Gypsum crystals formed in the mineral saturated sea brine and sank to the ocean bed.

How does volume describe a cell?
Answer:
As a cell grows bigger its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.

A structural change in the alpha-factor of Saccharomyces (a type of yeast) is shown to render the molecule defective. What effect would this mutation have on the reproductive behavior for this yeast cell species? Justify your claim by discussing cell signaling and response events?
Answer:
The description would be described throughout the interpretation segment following, and according to the particular circumstance.
Explanation:
The "α" factor would be a peptide thirteen amino acid pheromone naturally produced throughout alpha cells within Saccharomyces cerevisiae. It assists throughout the mechanism of recombination among 2 yeast cells. This would be recognized as "α" factors matching. The mutated gene of the factor generating gene can lead to decreased matching. The only functioning alpha component genes include MF "α" 1 as well as MF "α" 2.different between algae and fungi

This diagram represents a solid object with a mass of 120 grams. What is the density of the object?
a. Find the volume of the object
b. Find the density of the object.
Answer:
a. 30 cm³
b. 4.33 g/cm³
Explanation:
a Volume of the object = l*w*h
l = 5 cm
w = 2 cm
h = 3 cm
Volume of object = 5*2*3 = 30 cm³
b. Density of the object = mass of the object / its volume
Mass of object = 130 grams
Volume = 30 cm³
Density of the object = [tex] \frac{mass}{volume} = \frac{130}{30} = 4.33 g/cm^3 [/tex]

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte Count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
O Kaya's antigens were attacking the tissue.
O Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count?
The best explanation for why Kaya's lymphocyte levels were increasing is Kaya was not tissue-typed prior to her surgery, and her body is mounting an immune response. Therefore option 3 is correct.
Lymphocytes are a type of white blood cell that plays a crucial role in the immune response of the body. They are responsible for recognizing and targeting foreign substances, such as antigens, to protect the body against infections and diseases.
In Kaya's case, her lymphocyte levels increased both a week and a month after the transplant. This suggests that her immune system is responding to the presence of the transplanted organ.
The increased lymphocyte count indicates an ongoing immune reaction, which is typically characterized by the proliferation and activation of lymphocytes.
