In the picture below ions, or charged particles, are being pumped through the cell membrane.
Why do they require energy to transport across the membrane?
Answer: well if i had a picture it wouldve helped more but typically if a particle is moving into the cell, it doesnt require any energy, however moving particles outside of a cell requires a large amount of atp.

Which of the following statements describes the structure of the plasma membrane?
a It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.
Answer:
A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
Explanation:
The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.
Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.
This is why option A is the correct one.
You can see an image of the cell membrane's structure to help you visualize this below:

Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?
Answer:
3/16
Explanation:
This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).
In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:
9/16 of Round, yellow offsprings (R_Y_)
3/16 of Round, green offsprings (R_yy)
3/16 of Wrinkled, yellow offsprings (rrY_)
1/16 of wrinkled, yellow offsprings (rryy)
Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

People who work close to aircraft at an airport are given protective headsets to wear to help prevent hearing damage, but other people who work in places that are loud enough to damage their hearing, such as nightclubs, get no protection at all. Is this reasonable? What could be done about it?
Answer:
People who work on aircraft need the headsets to talk to the plane and other workers on it. People who work in nightclubs are probably used to the noise tho.

Question 39
True or False Animal cells contain a cell wall?
Analyze “Diagram B." Of the four answers provided, which answer clearly interprets this graph?
A. The wavelengths of sunlight between 100nm and 700mm aie the wavolengths thit are absorted by chirophyll and that drive photosynthesis
B. The wavelengths of sunlight between 400nm and 700nm are thin wavelengiis at a abnarted by the mitochondria and that drive photosynthesis
C. The wavelengths of sunlight between 400nm and 700mm aro thi wavolungths that are absorted Iy the mitochendria and that drive cellular respiration
D. The wavelengthN of night between 400nim and 700nm are the wavelengths that are lnortet by chlorophyll and that drive cellular respiration
As per diagram B of the four answers the wavelength. The wavelength are given in the visible bands and range form 400 to 700 nm. As per the absorption efficiency the band B has larger capacity than the band A.
Hence the wavelength of sunlight between the 400nm and the 7000nm ae the wavelengths that are absorbed by the and mitochondria that drive the process of cellular respiration.Hence option C is correct.

2. Explain how to focus a microscope using the high power lens. Include any safety issues you need to be
aware of
Answer.
Type your answer her to focus a microscope using the high-power lens you have to use the focus adjustment
knob but be careful because if you crank down too hard you can damage the microscope and the slide
Is my answer right
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.
Hope it helps!

Which one of the following factors does NOT affect Earth’s climate?
A. Ocean Currents
B. Energy from the Sun
C. Elevation
D. Soil Composition
Answer:
D
Explanation:
its just not any other one
Our soil cleans our water, feeds our trees and crops with vital nutrients, and controls numerous significant greenhouse gases in addition to helping to maintain the Earth's temperature. Thus option D is correct.
What is the soil impact on Earth climate?On a smaller scale, soil can also affect climate. More so than drier, looser soils, wetter or denser soils hold heat and stabilize the environment from temperature variations.
In deserts, the temperature can rise by more than 60 °F in a single day. The largest repository for terrestrial carbon is healthy soil. In the carbon cycle, soils are essential because they absorb carbon from decaying plant tissue.
By storing carbon (carbon sequestration) and reducing greenhouse gas emissions in the atmosphere, soils can be effectively managed to mitigate climate change.
Therefore, soil composition factors does NOT alter Earth’s climate.
