what is the effect of food  availability/competition on natural selection

Explanation:

Something along those lines, this is similar to the Galapagos finches when there used to be just one species but due to natural selection and limited food due to competition, the beaks changed to be able to eat the other food s available that they originally could not eat. There are now about 14 due to this.

Incomplete dominance

Inheritance of characters are based on Mendelian principle. According to it, the blending of phenotype is called incomplete dominance.

What is Mendelian principle?

Gregor Mendel is known as father of modern genetics. For this Mendel performed experiment on pea plant.

The main principles of Mendelian genetics can be stated as follows:

Law of Independent assortment.Law of dominance.Law of segregation.

When different alleles of parents blend to form a mixed colored organism, this is referred as incomplete dominance.

O C. Interneurons are too slow at sending signals through the spinal
cord.
O D. Sensory neurons do not use neurotransmitters to send signals.

Answers

Answer:

Answer:c

Explanation:

The reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

What is the reflex?

The reflex is an automatic (read immediate and constant) bodily reaction to stimulation. According to Pieron, the reflex corresponds to any activity or variation of activity of an effector (muscle, gland, etc.)

With this information, we can conclude that the reflex reaction is important in certain situations because interneurons are very slow to send signals through the spinal cord.

A semipermeable membrane has a 2 percent salt solution on one side and a
15 percent salt solution on the other side. What will most likely occur?

A. Osmosis of water from a low concentration of salt to a high
concentration
B. Osmosis of water from a high concentration of salt to a low
concentration
c. Active transport of salt until all the salt is concentrated on one
side
D. Facilitated diffusion of salt until both concentrations are equal

Answers

Answer:

A

Explanation:

Water naturally travels from a low solute concentration to a high solute concentrated.

The correct answer is B. Osmosis of water from a high concentration of salt to a low concentration. This is due to the process of osmosis, which is the movement of water molecules from an area of ​​low solute concentration to an area of ​​high solute concentration.

What is the context of it ?

In this case, the high salt concentration is on one side of the semipermeable membrane and the low salt concentration is on the other side. Therefore, water molecules will move from the side with a higher salt concentration to the side with a lower salt concentration, resulting in the osmosis of water from a high salt concentration to a low concentration.

The other options are incorrect because they do not accurately describe the process that occurs. Option A is incorrect because it states that osmosis will occur from low to high concentration, which is the opposite of what occurs in this situation.

Option C is incorrect because active transport requires energy and is used to move molecules against a concentration gradient, which is not happening here. Option D is incorrect because facilitated diffusion does not require energy and is used to move molecules down a concentration gradient, which is not happening here.

A type of cellular transport is shown. Which description best identifies this type of cellular transport? Your answer: Osmosis, because energy is being used to move molecules with the concentration gradient. Active transport, because energy is being used to move molecules against the concentration gradient. Facilitated diffusion, because energy is being used to move molecules with the concentration gradient

Answers

Answer:

Active transport, because energy is being used to move molecules against the concentration gradient.

Explanation:

This picture shows active transport. That just means that energy is being used (in this case, ATP) to move molecules against their gradient (meaning, from low to high concentration). Molecules "naturally" diffuse from high-->low concentration, so to move in the opposite direction requires energy input. You can tell this because there are only 2 molecules on the top side of the membrane, but on the bottom side there are 13.

Why not A: This is not necessarily water, as in osmosis, and it's not going with the gradient.

Why not C: This is not facilitated diffusion, because molecules are going against, not with, their concentration gradient.

The description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

WHAT IS ACTIVE TRANSPORT:Active transport is a type of transport that requires the input of energy in form of ATP. This is because the movement of molecules is against a concentration gradient.

According to the diagram in this question, molecules are being moved into the cell with an input of ATP (energy).

Therefore, the description that best identifies this type of cellular transport is: Active transport, because energy is being used to move molecules against the concentration gradient.

Explanation:

A scale model is a physical representation of an object that has the same aspects as that of the object.

A scale model can be used in fields like engineering, film making,  salesmanship, etc

Length of the student's cell model = 15 cm

Why anaerobic respiration is rapid than aerobic respiration​

Answers

Answer:

The amount of pressure that is released.

Explanations:

Aerobic respiration is known as a major advantage, base of the amount of energy it releases. Aerobic respiration releases more energy than anaerobic respiration, causing it to become more rapid.

Answer:

Anaerobic respiration is a shorter process than aerobic respiration so a complete cycle of anaerobic respiration is shorter than one of aerobic respiration.

Explanation:

Aerobic respiration involves three stages: glycolysis (the breakdown of glucose into pyruvate), the Krebs cycle (the breakdown of pyruvate into carbon dioxide and hydrogen), and the electron transport chain (hydrogen produced in the Krebs cycle bonding to oxygen to form water).

On the other hand, anaerobic respiration has fewer stages. Anaerobic means 'without oxygen', and so the process takes place without needing any oxygen. In anaerobic respiration, glucose is broken down into pyruvate, just like in aerobic respiration, however due to the lack of oxygen, that pyruvate is broken down into either lactic acid (e.g. in humans), or ethanol (e.g. in yeast). This process is called fermentation, and it doesn't take as long as the Krebs cycle and the electron transport chain, so that's why anaerobic respiration is more rapid than aerobic respiration.
