Answer:
The populations become adapted to different environments and eventually become so different that they cannot imterbreed to produce fertile of spring.
Speciation is the evolution of one species into two different kinds , and when they become isolated , that is the final step , since they cannot interbreed any longer .

Hello, the correct answer is A) Nucleus, C) Cell membrane, E) Cytoplasm, and lastly F) Mitochondrion.
✨ I will now explain how I got these answers.. ✨
We do know that every cell at least needs a Nucleus, a Cell membrane, a Cytoplasm, and Mitochondrion.
If they didn't have any of these.. They wouldn't be alive.
If you've paid attention, you would know that these are the correct answers.

What role does cellular respiration play in the carbon cycle?
Answer:
Cellular respiration is the process by which organic sugars are broken down to produce energy. It plays a vital role in the carbon cycle because it releases carbon dioxide into the atmosphere. This means that cellular respiration can be thought of as the opposite of carbon fixation in the carbon cycle.

please help me
The relationship between the strangler fig and the cypress tree closely resembles one of parasitism but is not. It is considered commensalism.
Parasitism is when one organism uses another as a host in order to survive, which generated negative impacts for the host, which will usually end in death. The strangler fig uses the tree as a host in order to sustain itself structurally but does not siphon nutrients from the tree or directly kill it, therefore it is not a form of parasitism.
Commensalism is described as a relationship between two organisms, in which the benefits are gained by only one of the members, but neither of the two is harmed in any way.
The relationship between the strangler fig and the cypress tree is best described as commensalism, given that although the strangler fig does eventually cause the tree to die by encircling its roots and not allowing it to grow, it does not kill the tree directly in order to survive.

5.explain mastication peristalsis segmentation and the release of hormones and enzymes necessary for digestion
Answer:
Ingestion starts both chemical and mechanical digestion.The digestion process begins with ingestion. The teeth starts the process of digestion by masticating food. Mastication makes easier swallowing and faster chemical breakdown. During mastication, salivary glands secrete saliva to soften the food. Saliva contains the salivary amylase enzyme, which digests carbohydrates, and mucus, which softens food into a bolus.
Peristalsis is a series of wave-like muscle contractions that moves food. Segmentation involves contractions of the circular muscles in the digestive tract, and Mastication breaks down food so that it can go through the oesophagus to the stomach.
Hormones - The hormones released by the pituitary gland are gonadotropins (LH and FSH), growth hormone (GH), thyroid stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), prolactin, antidiuretic hormone and oxytocin.
Enzymes - Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
Pepsin, produced in the stomach. Pepsin helps break down proteins into amino acids.
Trypsin, produced in the pancreas. Trypsin also breaks down proteins.
Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
Explanation:
So we can conclude that,
mastication peristalsis segmentation is
breaking down food in a wave like muscle contractions of the circular muscles in the digestive tract.
Btw I am not really sure about it.
Mark as brainliest!
Answer:
Large food molecules (for example, proteins, lipids, nucleic acids, and starches) must be broken down into sub units that are small enough to be absorbed by the lining of the alimentary canal. This is accomplished by enzymes through hydrolysis. The many enzymes involved in chemical digestion are summarized

This part is used to bring the specimen into sharp focus. This part causes a very small up and down motion when used.
Answer:
Fine focus.
Explanation:
If you're referencing a microscope, then it would be fine focus. Coarse focus is a basic focus used to properly see a specimen, while fine focus enhance clarity and precision. To use both, you have to gently twist a knob until you can see the specimen at a desired clarity.
Here's a reference image if you need it, it's labeled all the parts of a microscope.

As a population of a species increases within a territory, which of the following most likely also increases?
A-immigration
B-carrying capacity
C-food supply
D-competition
Answer:
D) competition
Explanation:
They are going to be competing for their survival.
Hope this helps! :)
With the increase in the population of a species, the competition between them also increases.
How competition affect a population?An association between two or more individuals of the same population or two or more populations in which each negatively influences the other in access to a restricted resources like food, shelter, water, mates, nesting, etc is termed competition.
When the size of a population increases, one can witness more intense competition between the individuals of the population. The influence of competition is generally density-dependent, that is, at greater population density, there is an increase in competition. This will negatively affect the size of the population.
Thus, the correct answer is option D, that is, competition.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be
present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.
