Answer:
The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed: Metabolic flexibility.
Explanation:
The human body primarily uses two sources of energy, glucose and fat. Glucose is found in the bloodstream and stored as glycogen in muscles and the liver, and fat in adipose tissue and in fatty acids. Metabolic flexibility is the ability of the body to alternate between the different energy substrates according to the circumstances of each moment. People with good metabolic flexibility will find it easier to use body fat and perform better physically. At lower intensity during exercise, more fat is consumed and at higher intensity, more glucose. If that high intensity is maintained, glycogen stores will be depleted. So then, how much energy is stored, how much is needed and how it will be delivered, is part of the reading that our body performs. This cellular adaptation to the requirements is known as metabolic flexibility.

Which of the following is NOT a mechanism used to temporally regulate the activity of maturation-promoting factor (MPF)?
A. the presence of mitotic cyclin
B. specific dephosphorylation
C. glycosylation
D. specific phosphorylation
Answer:
C. glycosylation
Explanation:
The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of what
Answer:
This question lacks options, options are:
A) ADH
B) aldosterone
C) atrial natriuretic hormone
D) oxytocin
E) prolactin
The correct answer is B.
Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of aldosterone.
Explanation:
The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.
) Describe three benefits of CBT.
Answer:
1. CBT can be completed in a relatively short period of time compared with other types of talking therapies.
2. Research has shown CBT can be as effective as medicine in treating many types of depression and other mental health disorders.
3. Skills you learn in CBT are useful, practical and helpful strategies that can be incorporated into everyday life to help you cope better with future stresses and difficulties.
Explanation:
Cognitive behavioural therapy (CBT) is a talking therapy that can help you manage your problems by changing the way you think and behave.
CBT cannot remove your problems, but can help you manage them in a more positive way. It encourages you to examine how your actions can affect how you think and feel.
Talking and changing your behaviour can change how you think (cognitive) and what you do (behaviour). This can make you feel better about life.
CBT can help you manage problems, such as anxiety and depression and make them less likely to have a negative impact on your life.
There is always a risk that bad feelings you associate with your problem will return, but with your CBT skills it should be easier for you to control them.

The Vmax of the isoform of glycogen phosphorylase expressed in muscles is significantly larger than the isoform of the enzyme expressed in the liver enzyme. Explain the functional significance of this observation.
Answer and Explanation: In enzyme kinetics, one constant describing enzyme activity is Maximal Velocity (Vmax). It indicates how fast an enzyme can catalyze the reaction. It is dependent on substrate concentration.
As the muscle is an organ which needs a great amount of energy, the enzyme glycogen phosphorilase is very active on the organ, compared to the liver, where glicose is stored. So, the Vmax of glycogen phosphorylase expressed in muscle is faster than when expressed in the liver, means the enzyme in muscle has a bigger concentration of substrate and therefore will reach Vmax faster, i.e. will be significantly larger.

ok the role of the cell membrane in regulating how nutrients are gained and waste products lost.
Answer:
The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.
When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.
Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.

PLS HELP!!! What best describes the relationship between
P. caudatum and P. aurelia in Graph B?
Predation
Mutualism
Interspecific competition
Intraspecific competition
Answer:
Interspecific competition
Explanation:
Interspecific competition occurs when two different species occupy the same environment as they coexist and depend on the same limited resources for survival. As a result of these limited resources, there's competition between the different species with each species having their different levels of fitness. Their level of fitness determines how well they will complete with other species. This will also determine if they will go extinct or thrive in such environment where there's interspecific competition.
The graph given shows the growth of the relative population size of two different species grown together.
It shows that P. aurelia, with time, outcompetes P. coudatum.
This graph clearly suggest that interspecific competition has occurred. Both species are competing for the same limited resources.
P. aurelia has a greater fitness which enables it to outcompete the other species sharing the same environment with it.
Interspecific competition beats describes the relationship between the two species in graph B.
