Answer;
The enzyme structure begins to break downintermolecular bonds are broken
enzyme molecules gain kinetic energy.
Explanation;
Enzymes are proteins that play an important function in the body of catalyzing reactions in the body.
Enzymes work best at optimum temperature; low temperature lower than optimum temperatures deactivates them and higher temperature denatures them.
The shape of an enzyme depends on its temperature; when they get too warm they get loose, and at very low temperatures they get too tight. At optimum temperature or at the right temperature then they are just at the right shape and the chemical reactions they catalyze will be at optimal rate.
Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
Answer:
The correct answer is CONCAVE because they don't have a nucleus. I just took the test!
Explanation:
Human females produce egg cells through a process called oogenesis. This process involves stages of meiosis and maturation. Only a small number of egg cells will actually mature and be released during a woman's reproductive years.
Human females produce egg cells through a process called oogenesis. Oogenesis begins during fetal development, where billions of egg cells form in the ovaries. However, only a small number of these cells will actually mature and be released during a woman's reproductive years.
Oogenesis is a complex and regulated process that involves several stages. The primary stage is called meiosis, where the chromosomes in the developing egg cell undergo DNA replication and cell division to create haploid cells with half the number of chromosomes. These haploid cells are then referred to as secondary oocytes. The secondary oocytes undergo further maturation and, when fertilized by a sperm cell, can develop into a human embryo.

O glycolysis
O dehydration synthesis
O photosynthesis
Answer:
The correct answer is - cellular respiration.
Explanation:
Bread rising is due to the production of carbon dioxide by yeast in both aerobic and anaerobic cellular respiration. If there is a presence of oxygen, yeast performs aerobic respiration and produce carbon dioxide from sugar or other sources of carbohydrates.
In absence of oxygen, yeast performs anaerobic respiration or undergo fermentation to produce carbon dioxide and alcohol as waste products.
Thus, the correct answer is - cellular respiration.
Marine biologists study biological oceanography and the associated fields of chemical, physical, and geological oceanography to understand marine organisms.
Marine science recreates key role in the ongoing search to understand our world and to control its resources.
The interdisciplinary nature of the Marine Science curriculum will organise students to analyze deeply such co occuring issues as environmental alter, human clashes on the ocean, and biodiversity.
Thus, Marine biology is the study of marine organisms, their behaviors and relation with the environment.

It was found on the American Cancer Society website, and websites are unreliable.
It is information that is used for a variety of purposes and not just gathered for research.
It is from a self-reporting survey, and teens may not want to answer the questions honestly.
The information may be unreliable due to being outdated, sourced from a potential bias platform, not specifically gathered for research purposes, or collected from potentially unreliable self-report surveys from teens.
There are a few reasons why the data in question may be unreliable. Firstly, if the information is too old it may not accurately reflect current conditions or understandings. This could make it unreliable for contemporary research or decision-making purposes.
Secondly, while websites such as the American Cancer Society can be reliable sources of information, it is important to consider that not all websites are. Some may not be up-to-date, be subject to bias, or lack comprehensive peer review.
Thirdly, if the information is used for a variety of purposes rather than specifically gathered for research, it may lack the specific relevancy, depth, or focus necessary for certain studies which can limit its reliability.
Lastly, relying on self-reported data, especially from a demographic like teens, can introduce bias as participants may not feel comfortable answering honestly or may not recall information accurately.

D. None of the listed responses is correct.
The term most appropriate for the collection of blood vessels supplying the protective tissue surrounding the brain, which can potentially hemorrhage during severe head trauma, is 'meningeal blood vessels.' These vessels supply the meninges, consisting of the dura mater, arachnoid mater, and pia mater.
The collection of blood vessels supplying the protective connective tissue layers surrounding the brain that may experience a hemorrhage during a severe head trauma are most appropriately referred to as: A. meningeal blood vessels.
The meninges comprise three layers: the dura mater, the arachnoid mater, and the pia mater. These layers are supplied with blood from the meningeal blood vessels. The possibility of hemorrhage in these vessels is a common concern in severe head traumas, leading to conditions such as epidural and subdural hematomas.
