Recently in Antarctica, a penguin with all black feathers was
discovered. This trait had never been seen before. What is
the likely source for this "new" trait?
The penguin in question has a rare genetic mutation called melanism, which makes skin, fur, and feathers black due to a high concentration of the pigment melanin. It's basically the opposite of albinism, which is caused by a lack of pigment.

where can the fewest h+ ions be found on the pH scale, and the fewest OH- ions
The lowest [tex]H^+[/tex] concentration on the pH scale would be 14 while that of the [tex]OH^-[/tex] concentration would be 0.
pH ScaleThe pH scale ranges from 0 to 14 with 0 being the most acidic and 14 being the most basic or alkaline.
The more the [tex]H^+[/tex] concentration of a substance, the lower the pH, and the more the [tex]OH^-[/tex] concentration, the higher the pH.
Thus, at the lower extreme of the pH scale, the concentration of [tex]OH^-[/tex] is fewest, and at the higher extreme, the concentration of [tex]H^+[/tex] is fewest.

. Think of a type of cell that would frequently divide
Answer:
mostly any type of cell would but i think some of them are skin cells, the reason is because as you keep growing the body need to produce more skin cells also since you can get scratches here and there.

I am trying to dissolve popcorn butter and milk into water. I notice the milk
dissolves, but the popcorn butter does not. Why is this? *
Answer:
Because butter is an oil-like substance. Water is a combination of hydrogen and oxygen, oil on the other hand is not. For the two to mix the oil would have to break the hydrogen chain but that is not possible because then the water won't be water.
So most fats repel water, just think about it being hydrophobic :)
Hope that helps and have a great day!

The process of transferring energy during respiration occurs in a series of steps. This prevents too much heat from being released at one time. Maintaining an appropriate temperature is beneficial to an organism because A) enzymes need a proper range of temperatures to catalyze vital reactions B) cellular waste products can only be excreted in cooler temperatures C) hormones can only produce antibodies if temperatures are not excessive D) nutrients diffuse faster into cells when temperatures are lower
Answer:
A) enzymes need a proper range of temperatures to catalyze vital reactions
Explanation:
Cellular respiration is the process by which living cells synthesize ATP (energy). The synthesized energy is transferred for use in other activities. However, as stated in this question, the process of transferring energy during respiration occurs in a series of steps in order to prevent too much heat from being released at once.
The process whereby the living organism maintains an appropriate internal temperature is called HOMEOSTASIS, which is beneficial and key to an organism's survival because because enzymes need a proper range of temperatures to catalyze vital reactions. Enzymes are proteinous catalysts that gets denatured by certain factors such as high temperature, pH.

Compare and contrast sexual and asexual reproduction, including the advantages and disadvantages of each process.
Answer:
What are the advantages and disadvantages of both asexual and sexual reproduction?
Comparison chart
Asexual Reproduction Sexual Reproduction
Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected
Disadvantages No variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy
Answer:
Prokaryotes and eukaryotes vs. only eukaryotes
Mitosis and binary fission vs. meiosis
Both forms of reproduction
Two vs. four cells produced
Diploid vs. haploid cells produced
Advantages or disadvantages of each
Explanation:
The sodium-potassium pump regulates the amount of sodium and potassium inside of cells, particularly nerve and muscle cells. In this process, an ATP is burned, causing three sodium ions to be pumped out and exchanged for two potassium ions, which are pumped in by a membrane protein. Both ions go against their concentration gradients.
The sodium-potassium pump is an example of
a. phagocytosis.
b. passive transport.
c. active transport.
d. facilitated diffusion.
Answer:
Active Transport because it needs ATP
The energy for cellular respiration comes from the glucose that was made during photosynthesis
Answer:
True
Explanation:
Glucose and oxygen that are made with the process called photosynthesis are then used as starting products for cellular respiration. This cellular respiration later makes carbon dioxide and water are then in combination with sunlight the starting products for new photosynthesis.

Give three reasons why the villi in the small
intestine are perfect for absorbing food.
Answer:
Villi are specialized for absorption in the small intestine as they have a thin wall,
one cell thick, which enables a shorter diffusion path.
They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.
The biomolecule described below is a _______________.
a. lipid
b. monosaccharide
c. carbohydrate
d. protein
Answer: it’s lipid
Explanation:
The biomolecule described below is a lipid because they are large and non-polluting molecules.
What is the main function of lipids?Lipids are responsible for providing energy, being in the form of fat that our body stores the excess energy we consume through food to use in times of need.
They are substances whose main characteristic is the insolubility in polar solvents and the solubility in organic solvents (nonpolar), presenting a hydrophobic nature, that is, aversion to the water molecule.
Lipids have unique characteristics that allow them to be quickly identified, for example because they are large and non-polluting molecules.

Look at the images of different rocks.
Which two rocks have a fine-grained texture?
1 and 5
2 and 3
3 and 5
4 and 1
Answer:
1 and 5
Explanation:
Image 1 and 5 actually show fine-grained textures of rocks.
Fine-grained textures actually indicates that magmas that are formed at or near the earth's surface cool rapidly. It's known that when magmas cool fast, they prevent very large crystals from growing. When hand samples of fine-grained rocks are taken, they appear homogeneous throughout the rock.
