Answer: c
Explanation:
Function of protein macromolecule is to move things in and out of the cells.
What are proteins?
Protein is found throughout the body in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin which carries oxygen in your blood. At least 10,000 different proteins make up the human being.
Protein is made from twenty-plus basic building blocks called amino acids. Because body does not store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are known as the essential amino acids, and must come from food.

a nucleic acid molecules is a type
Answer:
biopolymer, or large biomolecule, essential to all known forms of life
Explanation:
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.

When an unstable Co-60 isotope undergoes alpha decay, the nucleus formed is
Answer:
The correct answer would be : formed nucleus is that of Mn.
Explanation:
Alpha decay is a process that is exhibited by unstable molecules to be more stable. During the alpha decay nucleus of the unstable element removes its two protons and two neutrons in a bundle that researchers call an alpha molecule.
Since a particle loses two protons during alpha decay, it changes starting with one component then onto the next.
Co has 27 protons and neutron in its nucleus emits a alpha molecules that contain 2 protons and 2 neutrons
27=2+z
z =25 in periodic table 25 atomic number of Mn.
Thus, the correct answer would be : formed nucleus is that of Mn.
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.

This LIQUID is WATER!
HOPE THIS HELPS!!
The cell organelle that stores water for plant cells is the central vacuole.
What is the organelle that stores water?
In plant cells, there is a large, membrane-bound organelle called the central vacuole. It stores a variety of materials, including water, and takes up a sizeable amount of the cell's space. The central vacuole can take up to 90% of the space inside mature plant cells.
The turgor pressure and structural integrity of plant cells are crucially maintained by the central vacuole. It holds molecules such as carbohydrates, ions, pigments, and water. Water builds up in the central vacuole, which contributes to turgor pressure and supports plant tissues by making cells rigid. Furthermore, the turgor pressure preserves the form and structure of the leaves, stems, and other plant organs.

Which of the following is the long notation for 3.45 x 10^10? A 3,450,000,000 B 345,000,000,000 C 34,500,000,000
Answer:
C. 34,500,000,000
Explanation:
Firstly, 3.45 x 10^10 is said to be in a standard form, which is a simpler way to write relatively large or small numbers. Standard forms make use of powers of ten, which means that how many tens can be found in such number.
The power of ten of a small number is written with a negative sign. For example; 0.004 is written as 4 × 10^-3 while the power of ten of a large number is written with a positive sign. For example; 3.45 x 10^10 means the number is large.
In order to convert a standard notation to an expanded notation, one moves the decimal point to the right by the number of times indicated on the index. For example, 3.45 x 10^10 is written as 34,500,000,000 in long notation form by moving the decimal point to the right 10 times (as indicated on the index). A zero (0) is used to fill the blank spaces when moving the decimal point.
Hence, a standard notation of 3.45 x 10^10 can be written as 34,500,000,000 in long or expanded notation. This figure is 34 trillion, 500 million.

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.

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.

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.

Strepsirhines have a special lower incisor called a Group of answer choices tooth comb. diastema. two-ridge tooth. bilophodont.
Answer: tooth comb
Explanation: Strepsirhines are any member of the clade (a group of animals or other organisms derived from a common ancestor species) Strepsirrhini, one of the two suborders (a taxonomic category below order and above infraorder) of primates. They have a special lower incisor called a tooth comb which consists of long, flat teeth with microscopic grooves, and used for grooming the fur.
Strepsirhines are a suborder of primates that includes lemurs, lorises, and galagos. They are characterized by a number of features, including a toothcomb, which is a specialized set of teeth in the front, the lower part of the mouth mostly used for combing fur during grooming. Hence option A is correct.
The toothcomb is made up of four lower incisors and two canines, which are fused together to form a single, continuous row of teeth. The teeth are flattened and have sharp, comb-like edges that are used to groom fur.
The toothcomb is a unique feature of strepsirrhines, and it is thought to have evolved to help them groom their fur. Strepsirrhines are nocturnal animals, and they spend a lot of time grooming their fur to keep it clean and free of parasites.
The toothcomb helps them to groom their fur more efficiently, and it also helps to distribute their scent, which helps them to communicate with each other.

A 24-year-old G1P1 woman comes to the office requesting contraception. Her past medical history is unremarkable, except for a family history of ovarian cancer. She denies alcohol, smoking and recreational drug use. She is in a monogamous relationship. She wants to decrease her risk of gynecological cancer. Of the following, what is the best method of contraception for this patient?
A. Female condoms
B. Male condoms
C. Copper containing intrauterine device
D. Progesterone containing intrauterine device
E. Combined oral contraceptives
Answer:
E. combined oral contraceptives
Explanation:
Oral contraceptives will decrease a woman's risk of developing ovarian and endometrial cancer. The earlier, higher dose oral contraceptive pills have been linked to a slight increase in breast cancer, but not the most recent lower dose pills. Women who use oral contraceptive pills have a slightly higher risk of developing cervical intraepithelial neoplasia, but their risk of developing PID, endometriosis, benign breast changes and ectopic pregnancy are reduced. Both hypertension and thromboembolic disorders can be a potential side effect from using oral contraceptive pills. Condoms and intrauterine devices will not lower her risk of ovarian cancer.
