Aerobic training increases blood flow to skeletal muscles except because C)Fewer type II fibers. So, option C is correct.
Aerobic training (otherwise called perseverance activities, cardio or cardio-respiratory activity) is physical exercise of low to extreme focus that relies essentially upon the high-impact energy-creating process. "Vigorous" is characterized as "connecting with, including, or requiring oxygen", and alludes to the utilization of oxygen to satisfy energy needs during exercise through vigorous digestion adequately.
Oxygen consuming activity is performed by rehashing groupings of light-to-direct power exercises for broadened times of time. Vigorous activity might be better alluded to as "exclusively oxygen consuming", as it is intended to be low-force an adequate number of that all starches are vigorously transformed into energy by means of mitochondrial ATP creation. Mitochondria are organelles that depend on oxygen for the digestion of carbs, proteins, and fats.

Each of the following molecules is processed by glycolysis to lactate. How much ATP is generated from each molecule?
(a) Glucose 6 -phosphate
(b) Dihydroxyacetone phosphate
(c) Glyceraldehyde 3 -phosphate
(d) Fructose
(e) Sucrose
(A) Glucose 6 -phosphate ; ATP is created by converting glucose 6-phosphate to lactate 3. As seen in the image, the purple shaded section is repeated twice (since DHAP is isomerized to PGAL), resulting in the generation of four ATPs.
When fructose 6 phosphate is transformed to fructose 1, 6-bisphosphate, one of these four is used. As a result, the net yield is 3 ATP.
(B) Dihydroxyacetone phosphate ; Two ATPs are created from dihydroxyacetone phosphate. Because the cycle only happens once, either from DHAP or PGAL (glyceraldehyde 3-phosphate),
(C) Glyceraldehyde 3 -phosphate; Two ATPs are created. Because the cycle only happens once, either from DHAP or PGAL (glyceraldehyde 3-phosphate),
(D) Fructose; Two ATPs are created from fructose. Fructose is first turned into fructose 1-phosphate, which is then transformed into glyceraldehyde. Glyceraldehyde is converted to glyceraldehyde 3 phosphate.
(E) Sucrose: 4 ATPs are created from sugar. Sucrose is broken down into glucose and fructose. 2 ATPs from glucose to pyruvate + 2 ATPs from fructose to pyruvate = 4 ATPs overall. (The net glycolysis yield is two ATPs. 4 ATPs are created and 2 are consumed, for a total of 4 ATPs.

Which of the following is a type of lipid or composed of lipids?
All of the reponses are correct
triglycerides
plasma membrane
cholesterol
oils
The answers are all accurate. Lipids, or substances consisting of lipids, include triglycerides, plasma membranes, cholesterol, and oils.
Lipids are substances that contain lipids, such as glycerides, plasma membranes, cholesterol, and oils.
Glycerol is esterified into three fatty acid chains with distinct lengths and contents to form lipid molecules known as triglycerides. Saturated or unsaturated fatty acid chains are the two types.
The phospholipid bilayers that make up plasma membranes are lipids. Glycerol, a head with a phosphate connection, and two fatty acid tails make up a phospholipid. Hydrophobic interiors and hydrophilic exteriors characterize phospholipids.
In the blood, a lipid called cholesterol is carried by proteins called lipoproteins throughout the body.
Liquid lipids exist in the form of oils. Lipids share a similar chemical composition. They contain glycerol esters attached to fatty acids in the form of long-chain molecules.
As a result, we can conclude that every response is correct. Triglycerides, cholesterol, plasma membranes, and oils are lipids or lipid-containing compounds.

Predict what would happen to regulation of the lac operon in the lacI gene were moved 50,000 nucleotides upstream of its normal location.
Regulation of the lac operon should be normal. The location of the lacI gene isn't important, because the gene produces a protein that diffuses within the cell to the operator.
The lacI protein experiences a conformational shift upon lactose addition, which alters its affinity for the lac O sequences.
However, a protein made by the lacI gene, which controls the lac operon, prevents RNAP from attaching to the operon's operator?Only once allolactose binds to it and renders it inactive can this protein be eliminated. The lacI gene produces a protein that is referred to as the lac repressor.
If the lac operon system is turned on, what will happen?Only when lactose is present and glucose is absent do the genes come into play.

How many germ (cell) layers are present in acoelomates?
Answer:
Acoelomates are animals that lack a body cavity, or coelom, and are characterized by having all of their internal organs packed closely together. Because of this, they do not have distinct germ layers, which are the three primary tissue layers that form during embryonic development in animals with a coelom. These three germ layers are the ectoderm, mesoderm, and endoderm, and they give rise to the different tissues and organs in the body. In acoelomates, there is no distinct separation of these tissue layers, so it is not possible to say how many germ layers are present.

While active transport is the movement which require energy (3), for example, sodium ion transport out of cells (4). Both of them are the movement across a membrane (6).
The cell membrane regulates the movement of particle in and out of cells. In terms of the concentration gradient and energy, there are some types of movement. Passive movement is a type of movement from high concentration to lower concentration so that doesn’t require energy in form of ATP. For example, osmosis and diffusion. Specially for facilitated diffusion, the movement is assisted by proteins. However the solute is moving down the concentration gradient. A transport of glucose into cells is through a facillitated diffusion.
