In 1665, Robert Hooke published micrographia a book in which observations he made with a microscope cause him to coin the term “cell”. He may have coined the term when he viewed a piece of dead cork, a type of plant, and thought it resembled the cells of honeycomb. If he had viewed a section of living cork, what might he have seen

What is a cell?
The fundamental units of all living things are cells. There are many billions of cells in a human body. They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
Cork cells are packed closely together, the cells are generally arranged in radial rows.
Separation among the cells is achieved by structures arising from the cork cambium called lenticels. These pore-like structures allow gases to be exchanged between the plant stem and the outside environment.

When a protein molecule permanently changes its shape on being heated, this is
known as _____
What word completes the sentence?
Answers
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.

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.
Answers
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.

If fewer cows are now producing more milk, what natural resources are saved in the dairy industry? What resources might be used more.
Answers
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).
