The process of converting nitrogen gas to ammonium is called nitrogen fixation. Decomposition of plants and animals also releases ammonium into the ground. This ammonium can be further converted to nitrate with the help of nitrifying bacteria. Returning nitrogen back to the atmosphere is called denitrification.

If the function of an aquaporin is inhibited, how would the transport of water into the cell be affected? (3 points)
A. Water molecules will no longer be able to cross the cell membrane.
B. Water molecules will move across the cell membrane at a much slower rate.
C. Water molecules will only be able to cross the cell membrane by active
transport
D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.

Answers

Answer:

D. Water molecules will move across the cell membrane at a faster rate with late regulation from the aquaporin.

If the function of an aquaporin is inhibited, water molecules will move across the cell membrane at a much slower rate. Thus, the correct option for this question is B.

What is the function of Aquaporin?

The fundamental function of most aquaporins is to conduct the transport of water molecules across the cell membrane with respect to osmotic gradients that are significantly constructed by active solute transport.

Aquaporins are transmembrane proteins that remarkably form the channels and facilitate the rapid transportation of water molecules in both directions of the cell membrane.

If the function of an aquaporin is inhibited, the water movement is facilitated by diffusion also. So, a slow rate of water movement is carried out in the absence of aquaporins.

Therefore, water molecules will move across the cell membrane at a much slower rate, if the function of an aquaporin is inhibited. Thus, the correct option for this question is B.

Which of the following changes demonstrates a chemical property? *
O A substance breaks in half
A substance combusts (burns)
O A hammer bounces off a substance
O A substance floats in water

Answers

Answer:

The correct answer is B. Combustion is a chemical change. When a substance is burned, it forms new substances. Therefore, combustibility is a chemical property because it can only be observed when a substance undergoes a chemical change.

Explanation:

Hope that helps!

Answer:

The answer would be "A substance combusts (burns)".

Explanation

All of the other options are basic physical changes that don't alter the substance on a molecular level, whereas burning a substance permanently changes the molecular makeup.

Which answer best explains the difference between protists and bacteria?

A. Bacteria are prokaryotes and protists are eukaryotes

B. Bacteria have a cell membrane while protists do not

C. Bacteria have ribosomes while protists do not

D: bacteria have cytoplasm while protists do not

Answers

Answer:

The correct option is A. Bacteria are prokaryotes and protists are eukaryotes

Explanation:

The major difference between BACTERIA AND PROTISTS is the Bacteria are PROKARYOTES in nature and they dont have what we called nucleus reason been that their microbes are single celled microbes while protists on the other hand are EUKARYOTIC in nature and they have nucleus and they can either have a single-celled or have more than one celled.

The Second difference is that protists can only be found in the area or surrounding that are mostly moisture while bacterial on the second hand can be found in every area, environment or surrounding.

Therefore the answer that best explains the difference between both protists and bacteria

Is option A which states that Bacteria are PROKARYOTES while protists are EUKARYOTES.

A wildlife biologist and her team counted 150 lizards in a 25 km area. What is the population density

Answers

Given parameters:

Number of lizards  = 150 lizards

Area of the study = 25km²

Unknown:

Population density = ?

Solution:

Population density refers to the number of organisms per area in a particular location.

Mathematically;

     Population density  = [tex]\frac{Total Population}{Area}[/tex]  

    Population density  = [tex]\frac{150}{25}[/tex]   = 6lizards/km²

The population density of the study area is  6lizards/km²

Which best explains how green plants absorb energy from the sun?


A) Sunlight heats up the outside of a leaf


B) Chemical Bonds in a glucose are formed


C) A photon strikes electrons in special molecules in a cell


D) Carbon dioxide combines with water to form glucose molecules.

Answers

Answer:

the answer is C

Green plants absorb energy from the sun when "A photon strikes electrons in special molecules in a cell"

Green plants are unique organisms being that they possess the ability to capture and utilize energy from the sun. This is possible because they possess special pigments in their CHLOROPLAST called CHLOROPHYLL. The general process whereby green plants capture and utilize sun's energy is called PHOTOSYNTHESIS.

During photosynthesis, a photon of light strikes electrons in the thylakoid lumen of the chloroplast. This facilitates the synthesis of ATP (energy) in further reactions that takes place in the chloroplast.

Therefore, green plants are able to obtain energy from the sun when photons (beam of light) strikes electrons in their CHLOROPLAST.
