Which statement is true concerning visible light and the
electromagnetic spectrum?
All electromagnetic radiation is considered to be
visible
b
Visible light is not part of the electromagnetic
spectrum
Visible light is a large portion of the
electromagnetic spectrum
d
Visible light is a small portion of the
electromagnetic spectrum,
Answer: D
Explanation: visible light makes up only a very very, very small portion of the entire electromagnetic spectrum
The true statement concerning visible light and electromagnetic radiation is considered to be - d. Visible light is a small portion of the electromagnetic spectrum.
The electromagnetic spectrum is the range of frequencies of electromagnetic waves or radiations. This spectrum also gives an idea about the wavelengths of electromagnetic radiations. The part of the spectrum on their higher to lower energy or frequency range from [tex]10^{4}[/tex] Hz to [tex]10^{18}[/tex] Hz are:
gamma raysX-raysultraviolet radiationvisible lightinfrared radiationradio waves.The visible light is the very small part of the electromagnetic spectrum that ranges from the [tex]400*10^{14} Hz[/tex] to [tex]800*10^{14} Hz[/tex], Visible light is the light that the human eye can see.
Thus, the correct answer is- option d.

Which of these transport processes is the major means by which Na+ is transported across the membrane of neurons? Why?
A) both II and III because the activity of the neuron varies
B) I because Na+ is so small it can freely diffuse into the cell
C) III because Na+ is actively transported out of a neuron to maintain extracellular concentration
D) II because Na+ is charged and cannot cross the hydrophobic interior space of the cell membrane
Answer:
i think it’s C
Explanation:
I. is diffusion
II. is facilitated diffusion
III. is active transport
the third diagram makes most sense to me
Transport processes is the major means by which Na+ is transported across the membrane of neurons,I because Na+ is so small it can freely diffuse into the cell.

The answer is "Long." "Long" is not a type of muscle; it seems to be an incorrect option. The correct options for types of muscle are Cardiac, Skeletal, and Smooth.
These are the three main types of muscles found in the human body. Cardiac muscles are found in the heart, skeletal muscles are attached to the skeleton and enable voluntary movement, and smooth muscles are found in various organs and control involuntary movements.
Therefore, "Long" is not a recognized type of muscle and does not fit within the categories of cardiac, skeletal, or smooth muscles.

Answer:
D
Explanation:
I am taking the test
The statement describes the property of the asthenosphere, which is that the pressure is higher than the earth's crust.
What are the properties of the asthenosphere?The asthenosphere is the denser and weaker layer below the mantle of the lithosphere. It is approximately 100 kilometers (62 mi) and 10 kilometers (255 mi) below the Earth's surface.
The asthenosphere is the part of the upper mantle below the lithosphere that participates in plate tectonic movement and isostatic regulation. It consists of peridotite, a rock that mainly contains the minerals olivine and pyroxene.
The asthenosphere is the mechanically weak and flexible region of the Earth's upper mantle. It is located under the lithosphere, approximately 80-200 kilometers below the earth's surface and extends to a depth of 700 kilometers.

What do animals do with the carbon dioxide produced in their cells during cellular respiration?
Answer:
Explanation:
During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. ... They release the carbon dioxide into the air as a waste product. Plants help animals and animals help plants.
The carbon dioxide produced in animal cells during cellular respiration is considered a waste and must be disposed of accordingly.
The carbon dioxide generated from cellular respiration in animal cells must be disposed off the cell because their build-up can be toxic to the cell.
Being a gas, carbon dioxide is got rid of by diffusing out of the cell while the oxygen required for cellular respiration usually diffuses in.
When carbon dioxide is allowed to accumulate in the cell, it might affect other processes such as the partial pressure of oxygen in the cell, and so on.

Describe the overall trend in corn yield from 1988 to 2008. How does the trend in corn yield during the time compare to tends for total nutrients and nitrogen?
The trend in the corn productivity shows an increase from the year 1988 to 2008.
This is because of high yielding varieties of corn, new technology and application of optimum dose of fertilizer and other agronomic activities. The trend in corn yield for the nutrients and nitrogen increases because new high yielding varieties needs more nitrogen as well as other nutrients as compared to local or old varieties so it is concluded that productivity and nutrients uptake increase with the passage of time.

Answer:
Heterotrophs obtain energy by eating plants and animals. Plants are autotrophs, absorbing the sun's energy through photosynthesis and making glucose. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

Explain the connection between the Nucleolus, ribosome, and RER.
AnswerExplanation:
The nucleolus is a region of the nucleus where ribosomal RNAs are synthesized.
Ribosomes are protein synthesis factories made from the ribosomal RNAs that are synthesized in the nucleolus and ribosomal proteins.
Sometimes, ribosomes are found free in the cytoplasm, other times they are attached to the endoplasmic reticulum, forming the rough endoplasmic reticulum. The rough endoplasmic reticulum is the site of protein synthesis for proteins that are to be secreted from the cell
