Animal cells do not have cell walls, so their membranes act as walls. Therefore if put as an analogy, A function of the cell membrane in an animal cell is to a plant cell's wall.
Which statement explains the relationship between the density of a material and its movement in Earth’s interior?
Cooler materials move from Earth’s mantle to the lithosphere.
Cooler materials are highly dense, causing them to sink to the outer core.
Warmer materials sink to the mantle because their density slowly decreases.
Warmer materials have a high density, causing them to rise to Earth’s surface.
Answer:
The answer is B, Cooler materials are highly dense, causing them to sink to the outer core.

If fewer cows are now producing more milk, what natural resources are saved in the dairy industry? What resources might be used more.
Answer:
used less: water, grass, hay, and wheat.
used more: bottles, plastic, carboard (for boxing), wood (box crates).
Explanation:
The natural resources that would be saved in such a scenario are the ones being used to maintain the cows alive and healthy. These include water, grass, hay, and wheat. These natural resources are saved because fewer cows need to be maintained for the same or more amount of milk to be produced. With more milk being produced means all of the resources needed for packaging and selling the milk will be used more, such as bottles, plastic, cardboard (for boxing), wood (box crates).

Marissa is an extremely curious sixth grader. During a snow day she looked out her window and saw a truck spreading something all over the road. After the truck went past Marissa's house, she had a snack, put on her snow boots, hat, coat, and gloves and went outside to play. She walked over to the edge of her driveway and observed salt all over the roadway, but not the sidewalks or her driveway. She also observed some of the snow and ice had melted off the roadway but not her driveway or sidewalks. She wondered if the ice and snow melting was due to the salt?

6. Energy is stored in the form of food.
Photosynthesis
Respiration
Both
Answer:
Respiration
Explanation:
Food energy is chemical energy that animals (including humans) derive from food through the process of cellular respiration. Cellular respiration may either involve the chemical reaction of food molecules with molecular oxygen (aerobic respiration) or the process of reorganizing the food molecules without additional oxygen (anaerobic respiration).

I'm pretty sure:
a) pepsin optimal pH: 3 and lipase optimal pH:8
b) No, because the stomach needs to be acidic and have an acidic pH but lipase is considered alkaline because its optimal pH is between 8-14 meaning it's an alkaline.

The transportation of substances in and out of a cell is regulated by the cell membrane.
Describe two factors that increase the rate of diffusion of a molecule across the cell membrane.
Answer:
membrane surface area and the concentration gradient
Explanation:
the larger the surface area of the membrane that a substance is diffusing through , the faster the rate of diffusion . Likewise , the bigger the difference in the concentration between 2 areas , the greater the concentration gradient and the faster the rate of diffusion.

What is the optimal soil pH for most plant growth? Why is this so?
Select one:
A. 4-5, due to the fact that the majority of soil nutrients are only present at the this pH
B.6-7, due to the fact that the majority of soil nutrients are soluble at the this pH
C. 9-10, due to the fact that the majority of soil nutrients can be absorbed by roots at the this pH
D. 6-7, due to the fact that the majority of soil nutrients are created in soils with this pH
Answer:
B
Explanation:
6.0-7.0 pH is important because most horticultural crops will grow satisfactorily in these levels. It also influences the amount of pH available in the soil, like answer B states.

When a protein molecule permanently changes its shape on being heated, this is
known as _____
What word completes the sentence?
Such a process is known as denaturation. In this case where a protein "permanently" changes its shape (i.e., denatures) on being heated, the protein is irreversibly denatured.
When a protein molecule permanently changes its shape upon being heated, this is known as denaturation. It broke the shape of the protein.
What are proteins?Proteins and nucleic acids can get denaturized when they are exposed to high temperatures, pH extremes, non-physiological quantities of salt, organic solvents, urea, or other chemical agents.
Denaturation is a biological process that alters a protein's molecular structure. Denaturation is the name given to such a process. A protein is irreversibly denatured when it undergoes a “permanent” change in shape (i.e., denatures) in response to heat.
Therefore, denaturation is the process by which a protein molecule undergoes a permanent change in form when heated. Thus, the word that completes the sentence is denaturation.

A city spends $15 million on a beach nourishment project that adds 1.8 million cubic yards of sand to 3 miles of beach. What is the cost per cubic yard of sand?
Answer:
The answer is $8.33 per cubic yard.
Explanation:
This problem is just a normal math equation. You divide the price by how much space you are covering to get the smallest ratio(15 million divided by 1.8 million). After dividing you get the answer of $8.33 per cubic yard.

6. It is a criticism of many population ecologists that the pattern of population increase and frequent crash of the deer
population would have occurred even if the bounty had not been placed on the predators. Do you agree or disagree with
this statement? Explain your reasoning.
Answer:
I disagree with this statement.
Explanation:
I disagree with this statement because predators do have a place in ecosystemsto keep prey species from becoming overpopulated, therefore the extent of theoverpopulation would most likely have been much less if the natural predatorswere allowed to play a role in controlling the deer population.
Natural predators and prey have a beneficial interaction. Disagree with the assertion since predators have a big impact on controlling the size of their prey population and preventing overpopulation.
What is the population?The population reaches a maximum point that is determined by the amount of space or food that is available. The carrying capacity, or K, is the equilibrium point where the natality and mortality rates are equal to one another. K is a constant that equals population size at this point.
However, the predator-prey interaction that exists in the presence of a predator causes the deer population to drop.
Therefore, disagree because predators are crucial in controlling the size of their prey's population and preventing overpopulation.
