Answer:
Diffusion.
Explanation:
Oxygen in the lungs diffuses from the alveoli into your bloodstream through capillaries and carbon dioxide diffuses from the bloodstream into the lungs also through these capillaries. The carbon dioxide is then breathed out.

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.

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).
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).
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.

What is the Cell cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next. It can significantly be divided into two phases. They are as follows:
Interphase.M-phase (Division phase).The Interphase of the cell cycle is the longest phase which consists of three phases. They are the G1 phase, S-phase, and G2 phase. In this phase, the cell replicates its genetic content and appears to be in a normal state.
In metaphase, the chromosomes usually align in one plane and form an equatorial plate. Anaphase is the smallest phase of mitotic cell division. In this phase, the centromere splits, and centromeres migrate to opposite poles.
In telophase, two sets of daughter chromosomes reached the opposite poles and are converted into chromatin thread. After karyokinesis, the cytoplasm gets converted into two equal parts. This is known as cytokinesis.
Therefore, the letter answers to the matching image is well described above.
