Answer:

Active transport is when substances move against the concentration gradient and go from low to high. Diffusion is when substances move with the concentration gradient and go from high to low.

Active transport uses energy but diffusion and facilitated diffusion doesn’t that why they differ from each other

hopefully that helps :)

Andrei [34K]

Answer:

The correct option is D) immigration

Explanation:

Immigration can be described as the movement of an organism to another place for living. As the scenario in the question tells, the population of the endangered Philippine eagle could be seen only in one place hence we can say that the immigration rate of these organisms was zero because they could not be seen in any other place.

Other option, like option B, cannot be correct because mortality refers to the death rate and obviously many organisms of the species died due to which it became endangered.

The purple spots on colorless background of corn kernels observed by barbara mcclintock were the result of _______.

vitfil [10]

The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.

<h3>What are the genetic elements found in corn?</h3>

A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
The first recognized genetic instability was caused by genetic transposition.
The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
These spots were caused by the Ds components of the color gene being transposed.
The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.

Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.

PLS help!!!!!! brainliest!!!! which activity produces an action potential in nerve cells?

olga55 [171]

Answer:

C. release of neurotransmitters

Explanation:

The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about -55 mV a neuron will fire an action potential.

During what energy from the sun is stored in the bonds of sugar molecules

Dimas [21]

The energy from sunlight is stored in the chemical bonds of molecules. ..... during day, CO2 slowly used to make glucose while stomata are closed ... purpose is to produce ATP(energy stored in chemical bonds of sugar) and breakdown.
