HELP!!!!!!!!!! Which of the following statements regarding membrane transport is false? I will mark brainliest!!!!!!!

Answer:

the forces between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them

Answer:

The force becomes 4 times as much when the distance is halved.

Explanation:

F1 = k*q1 * q2/r^2 = kq^2/r^2

F2 = kq^2/1 / (r/2)^2

Set up a proportion using F1/F2 as you reference.

Notice that you don't know any number that can be used in this equation. However k q^2 does not change as you move the two charges closer together. That being so, you can still show what happens to F1 and F2.

F1/F2 = 1/r^2 // 1/(r^2/4)

Take the denominator, invert the fraction and multiply. That creates another cancellation.

F1/F2 = 1/r^2 * r^2 /4 1

F1/F2 = r^2 // r^2/4          which allows you to cancel r^2

F1/F2 = 1/4                       Now you need to interpret F1 and F2. Cross Multiply

4F1 = F2

Answer:

413,55 ppm

Explicación:

413,55 ppm es el nivel de dióxido de carbono actual en comparación con el nivel de dióxido de carbono que es de aproximadamente 280 ppm antes de la revolución industrial. Esto significa que la revolución industrial aumenta la concentración de gas dióxido de carbono en la atmósfera, que es la principal causa del derretimiento de los glaciares, el cambio climático y el calentamiento global. Hay una gran cantidad de dióxido de carbono que se libera de las industrias, lo que es responsable del aumento de la concentración de dióxido de carbono en la atmósfera.

Complete question:

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.

Group of answer choices

A) behavioral . . . prezygotic

B) mechanical . . . postzygotic

C) temporal . . . prezygotic

D) gametic . . . postzygotic

Answer:

A) behavioral . . . prezygotic

Explanation:

The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.

There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.

Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.

There are different types of reproductive barriers.

Pre-copulatory o pre-ziygotic:

Postzygotic mechanisms or barriers include

Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

Select this answer as the BRAINLIEST!!

Answer:

I think the answer is Selective breeding takes place over many generations. These are the main steps for both plants and animals involve:

Decide which characteristics are important enough to select.

Choose parents that show these characteristics from a mixed population. They are bred together.

Choose the best offspring with the desired characteristics to produce the next generation.

Repeat the process continuously over many generations, until all offspring show the desired characteristics.

Answer:

Volume = 113.112 m³

Explanation:

Given the following data;

Radius = 2 meters

Height = 9 meters

To find the volume of a right circular cylinder;

The volume of a right circular cylinder is calculated by multiplying the area of its circular base with the height of the cylinder.

Mathematically, the volume of a right circular cylinder is given by the formula;

Volume= πr²h

Where;

r is the radius of the circular base.

h is the height of the cylinder.

Substituting the values into the formula, we have;

Volume = 3.142 * (2)² * 9

Volume = 3.142 * 4 * 9

Volume = 113.112 m³

Answer:

She doesn't need to worry if her parathyroid glands are working.

Explanation:

Although Annette has to worry about the impacts of thyroid gland removal and synthetic thyroid hormone intake, the calcium levels in her body need not be a concern as long as her parathyroid glands are functioning normally.

This is because the parathyroid glands are responsible for regulating calcium levels in the blood, through the production of parathyroid hormones or parathormone.

Answer:

Transcription uses the DNA to make RNA molecules.

Answer:

Hence the correct answer is Blood flow is shifted from the brain to the extremities.

Explanation:

Blood flow is shifted from the brain to the extremities - most marine mammals have an in-depth network of blood vessels towards their brain which is understood because of the retia mirabilia. These reduce the temperature in the extremities.

Answer:

Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.

All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.

Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.

Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.

Hence, All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

Answer:

Feature detection

Explanation:

Feature detection involves different neurons that are activated in response to specific stimuli. For example, feature detectors are activated in the cerebral cortex through visual stimuli of specific shapes or patterns. These neurons become more and more complex as the stimuli also become progressively more complex and specific. Featured detector neurons have been identified in the toad vision, where they have been involved in the toad's behavior in response to worm-like moving stimuli (e.g., orienting), and the bat auditory cortex, where they have been involved in the measurement of the distance between the bat and its prey.

Answer:

if  An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents

If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.

Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.

The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.

The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.

Explanation:

Iron melts at 1538 °C after loosing it's magnetic property at 770 °C

If an iron ball is heated from 50 degree celsius to 2000 degree celsius.  The state will be liquid state as it is  loosing it's magnetic property

The magnetism  property is defined as the force exerted by magnets by either attracting or repulsing each other.

In a magnetic field of a matter, two important basic particles are the magnetic moments and the electric currents. It is depend on  pressure, temperature, and the applied magnetic field.

Magnetic materials are up three types such as  diamagnetic, paramagnetic and ferromagnetic.

Two Sources of magnetism are electric current and Spin magnetic moments of elementary particles.
