A cell membrane is very specific about what It allows across. How does this help the
cell?
XO A. It helps the cell absorb as many different molecules as possible.
O B. The cell works better when it contains fewer proteins.
C. Transport proteins allow only enzymes to pass through the membrane.
D. It is better for the cell if most molecules are prevented from entering.
Incorrect
It isn’t A
What statement about enzymes and pH is true?
A Most enzymes require a very acidic environment to function well.
B Most enzymes require a very basic environment to function well.
C Enzymes are unaffected by changes in pH levels.
D Enzymes require a specific range of pH values to function.
Answer:
D. Enzymes require a specific range of pH values to function.
Explanation:
Enzymes function the best in a neutral pH, rather than in very acidic or basic environments.
Enzymes are very affected by changes in pH levels because they perform much better in neutral environments.
Sweating when hot, shivering when cold, blinking when a bright light hits
one's eyes. These are examples of which characteristic of life?
organization
response to stimuli
growth and development
heredity (genes)
Answer:
I think it must be response to stimuli
Explanation:
Some receptors can detect several different stimuli but they are usually specialised to detect one type of stimulus: light - photoreceptors in the eye. ... touch, pressure, pain and temperature - different receptors in the skin. taste and smell - chemical receptors in the tongue and nose
can there be justice when it comes to the environment and how
Answer:
Environmental justice is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.
Explanation:
Environmental justice issues and examples include inadequate access to healthy food, inadequate transportation, air and water pollution, and unsafe homes.

Please help with this question! Last time I asked a question people were being unfair and would try to get points of me with non real answers. it has been happening a lot so please real answers! Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic plates?
Explanation:
Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
How is a clade differentiated from another clade
Answer:
A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.
Explanation:
A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.
Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades
Answer:
A clade is a monophyletic grouping in which all the organisms stem from the same branching point.
Explanation:
The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.
You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes
Answer:
C. Phenotypes
Explanation:
Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.
Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.
So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.
Hence, the correct option is "C. phenotypes".
Select the best answer for the question.
A student conducts an experiment to see how music affects plant growth. The student obtains four identical
plants. Each one is potted in the same type of soil and receives the same amount of sunlight and water each
day. Plant A listens to classical music for three hours each day. Plant B listens to rock music for three hours
each day. Plant C listens to country music for three hours each day. Plant D does not listen to any music at
all.
1. In the experiment described in the scenario, what's the variable?
Answer:
A B and C because they all listen to music

Explanation:
Which correctly lists the three types of rock particles that make up soil? A. air, clay, and sand B. clay, water, and silt C. sand, clay, and silt D. silt, water, and air answer C.sand, clay, and silt
Answer:
option.c
Explanation:
It is correct
The three types of rock particles that make up soil are sand, clay, and silt. Thus, the correct option is C.
What are Rock particles?Rock particles may be defined as those particles that are formed by the weathering of sedimentary rocks and construct small tiny particles.
In the production of soil, water molecules and atmospheric air are not required significantly. The gathering of tiny rock particles constitutes the formation of soil.
Therefore, the correct option is C.
