what product of the light dependent reaction of photosynthesis is utilized in the light independent reaction
Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.A random mutation occurs and the GGA codon is changed to CGA. What effect does this
substitution have on the amino acid being called for? Explain your answer.
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Due to Base Substitutions Mutations.
What happens when a mutation changes a codon?
A nonsense mutation refers to a base substitution in which the changed nucleotide transforms the codon into a stop codon.
Such a modification leads to a premature termination of translation, which can badly affect the formation of proteins.
Thus, Base Substitutions Mutations take place.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?
Answer:b
Explanation:
The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
How net force will be calculated?
The net force acting on the bicycle is:-
F net = Total force acting on bicycle
In above question,
Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)
So,
Fnet = F1 + F2
Fnet = 150 N -84 N
Fnet = 66 N
Now the acceleration will be
Fnet = mass X acceleration
In above question,
Fnet = 66 N
Mass = 100 Kg
So,
Acceleration = Fnet/Mass
Acceleration = 66/100
Acceleration = 0.66 m/sec^2
Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.

Molecules 1 and 2 enter the cell and glucose leaves the cell through the process of ?
Answer:
-diffusion
Explanation:
Cells are usually surrounded by a bilipid layer called a plasma membrane. The membrane maintains selective permeability through the use of its transport proteins, pores and gated channels. Simple diffusion happens, as a method of passive transport, in cells through plasma membranes. The solutes travel through the plasma membrane in the process of diffusion from regions of high concentration to regions of low concentration; this occurs without the use of energy.
The solutes move in a specific direction down their concentration gradient. Here, glucose moves out of the cell through facilitated diffusion, a form of passive transport using carrier proteins. The other molecules (1 and ) enter the cell across the membrane through simple diffusion due to their low molecular weight- these may move across the membrane at will, or use transport proteins.
If a patient has a medical condition that causes his cells to absorb fewer than normal __________ molecules, this patient would likely feel very tired. Explain your reasoning
1. oxygen
2. fiber
3. starch
4. protein
You feel exhausted when your body is oxygenally depleted. When your lungs are unable to breathe in and out properly, fatigue sets in more quickly. Thus, option A is correct.
What is the less absorption of oxygen in cell to indicate?Necrosis, or cell death, occurs when glucose and oxygen are not provided to cells. It's interesting to note that cells can survive hypoxia.
According to the early research showing that acute oxygen deprivation triggers the intrinsic apoptotic pathway, there is a reduction in the potential of the mitochondrial membrane.
This starts a nasty loop. You're less likely to exercise when you're feeling tired as a result of a lack of oxygen.
Therefore, Numerous factors, such as a reduction in red blood cell concentration or a reduction in hemoglobin's oxygen saturation, can lead to a reduction in oxygen-carrying capacity.

explain why the suspension of isolated chloroplasts became alkaline when illuminated?
Answer:
Yes, protons are pumped across the membrane, but flow right back again through the ATP synthase. More important is that illumination is required for carbon fixation. As photosynthesis runs, the chloroplasts remove CO2 from the water they are suspended in. In solution, CO2 forms carbonic acid, so removing CO2 will reduce the level of carbonic acid, raising the pH.
Explanation:
Chloroplasts are the primary cell organelles involved in the conversion of light energy into stable chemical energy through photosynthesis. The chloroplasts will become alkaline due to a rise in pH and a reduction in carbon dioxide.
Chloroplast is the green-colored cell organelle, primarily involved in the conversion of light energy into chemical energy.
When the isolated chloroplasts are illuminated, the suspension in which chloroplasts are suspended becomes alkaline. It is assumed that protons are pumped in from the medium to the thylakoids.
As photosynthesis takes place, the chloroplasts remove carbon dioxide from the suspension, which causes an increase in the pH of the suspension.
Therefore, the formation of carbonic acid from the CO2 will raise the pH.

- Controls the entry of chyme into the colon: H. Ileocecal valve
- Substance that helps make or break a chemical bond: I. Enzyme
- A component of gastric juice: G. Hydrochloric acid
- Organ that releases bile into the small intestine: E. Gallbladder

- Fingerlike projection of small intestinal lining: D. Villus
- Absorption mechanism that requires energy: B. Active transport
- Absorption mechanism that does not require energy: C. Diffusion
- Carries fat-soluble vitamins: F. Lymphatic system
Explanation:
The pylorus is a part of the digestive system that connects the stomach to the duodenum. The ileocecal valve is a muscle localized between the ileum of the small intestine and the colon, whose main function is to limit the reflux of colonic contents. Gastric juice is a liquid consisting of hydrochloric acid, lipase, and pepsin, whose main function is to inactivate microorganisms. The gallbladder is a small organ that in combination with the small intestine are reservoirs for bile acid and regulate the biliary secretion of this acid. The bile acid is a fluid secreted by the liver that helps to digest lipids in the small intestine. Intestinal villi (villus in singular) are finger-like projections that increase the surface area for the absorption of nutrients in the small intestine. Active transport is the movement of molecules across cell membranes by using energy from ATP hydrolysis or by using an electrochemical gradient. Diffusion is the movement of molecules across cell membranes from a side of the membrane with higher concentration to the other side with lower concentration. An enzyme is a molecule (generally a protein) that is capable of accelerating the rate of a chemical reaction. Fat-soluble vitamins are absorbed in the small intestine and then they are transported through the lymphatic system to be released into the bloodstream.

What type of protist is an amoeba and how does it move?
Answer:
Explanation:
An amoeba is a classification of protist (single-celled eukaryotic organism that is neither plant, animal, bacteria, nor fungus) that are amorphous in shape. They move via forming 'feet-like' pseudopodia, which are also used for feeding.
Answer:
Explanation: Amoeba and sarcodines are examples of protists that move by pseudopods. Some animal-like protists move by using cilia. Cilia are hair-like projections that move with a wave-like pattern. The cilia move like tiny oars to sweep food toward the organism or to move the organism through water.
