Answer: Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum.

Explanation: Photons reflected by pigments in leaves are used by leaves to carry out photosynthesis is not true as the photons are absorbed as a source of energy by the pigments to carry out the process of photosynthesis.

Human beings can see only a small fraction of the wavelengths that make up the electromagnetic spectrum is true as only visible light is visible to human beings.

Photons are units of light that travel from the sun to leaves in the same way that particles travel through space is not true as photons travel from the sun to leaves by radiation in the form of electromagnetic waves and do not require any medium but particles require medium to travel.

The wavelengths that make up the electromagnetic spectrum each have the same amount of energy is not true as the electromagnetic radiations have different wavelengths and thus have different energies.

$E=\frac{hc}{\lambda}$

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the

castortr0y [4]

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.

How do organs relate to cells and tissues

pogonyaev

Simple....

as you've learned... cells create tissue..tissue creates organs...organs create organ systems..and organ systems create organisms. They all work together to create something...

An example:

muscle cell-->>muscle tissue-->>heart-->>circulatory system-->>the circulatory system makes up a part of the body.

Thus, your answer.

igor_vitrenko [27]

Answer:

Promotes and maintains under which nature and humans can co-exist indefinitely

Explanation:

The ability to sustain something is known as sustainability.

ecology defines it as a means of configuring civilization and human activity so that society, its members and its economies are able to meet their needs and express their greatest potential in the present, while preserving biodiversity and natural ecosystems, planning and acting for the ability to maintain these necessary resources for future generations.

What is the outer surface of Schwann cell in adjective form

NARA [144]

I am not sure if this question means the adjective form or the adjacent form? However, a Schwann cell is a type of glial cell and its main function is to support neurons. Adjacent to the Schwann cell are nodes of Ranvier which are gaps in the myelinated axons, and are believed to assist in potential generation among other things.
