Answer:
I am pretty sure that the answer is A.
Explanation:
Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.
I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!

Which is not a unique property of water
Answer:
A
Explanation:
All of the other options are specific to water, but quite a few liquids cool off a lot faster than water.
water cools very rapidly is not a unique property of water. Thus option A is correct.
what are the properties of water molecule ?It has no taste, odor, or transparency, where the nucleus of the oxygen atom attracts electrons strongly than the nuclei of the hydrogen atoms.
In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.
Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.
Surface tension is defined as the tendency of the surface to resist rupture when they are subjected to stress due to cohesive forces.

Why do planets close to the sun have thin atmospheres and the planets far away from the sun have thick atmospheres. Use what you know about the nebular theory.
Answer:
There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. The reason why the outer planets are larger is probably down to two major factors. The first is simply the amount of material available which may be accreted to a planet. Clearly, the further away from the Sun, the longer the orbit (twice as far means an orbit twice the physical length).

The swallowing phase where the velopharynx closes forcefully and larynx completely closes at 3 levels is the...
a. Tongue preparatory phase
b. Pharyngeal transport phase
c. Oral transport phase
d. Laryngeal transport phase
Answer:
b. Pharyngeal transport phase
Explanation:
During the pharyngeal phase, the vocal folds close to keep food and liquids from entering the airway.
Swallowing the velopharynx closes forcefully and the larynx completely close at the level of the pharyngeal transport phase this action seal the airway passage, hence option b is correct.
What is swallowing ?According to where the bolus is located, the swallowing process is often split into oral, pharyngeal, and esophageal phases. When consuming solid food vs drinking liquid, the food moves differently through the oral cavity and into the oropharynx.
The tongue closes the oropharynx while it is in the pharyngeal phase. The proximal pharyngeal wall and soft palate serve as a barrier to the nasopharynx.
The laryngeal entrance is sealed off by the vocal cords and arytenoids, and the epiglottis swings down to cover the laryngeal vestibule. These acts close up the pharyngeal cavity's airway.
Therefore at 3 levels, the velopharynx closes forcefully and the larynx completely closes in the pharyngeal transport phase action to seal the airway passage, hence option b is correct.

1. Where in the paramecium might you find proteins? Explain why?
How would you restate in your own words the law of conservation of mass?
Answer:
The Law of Conservation of Mass
In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Methamphetamine increases the brain's levels of dopamine, __________ and __________.
a) norepinephrine, serotonin
b) GABA, epinephrine
c) acetylcholine, enkephalins
d) glutamate, serotonin
Answer:
a) norepinephrine, serotonin
Explanation:
Neurotransmitters are special lipid-based molecules used in chemical signal transduction in the nervous system. They have receptor-specific roles in activating different regions of the central nervous system (CNS) and physiological responses. These include: dopamine, norepinephrine, and serotonin .
The CNS, which includes the brain and spinal cord, can be affected by certain drugs like methamphetamine. This drug is a stimulant that acts on brain regions such as:
prefrontal cortex the striatumthe nucleus accumbensIt causes the release of neurotransmitters while blocking their reuptake at synapses; meth is metabolized very slowly over time (12 hours). The buildup of dopamine, for instance, leads to altered moods, feelings of pleasure and euphoria.
Thus, this change or "high" leads to dependency by users for its mood-altering effect; however, less dopamine is released, and the pleasurable effects, become less potent. Studies show neurological damage with prolonged use, and habit formation and over time, addiction.

Mutations can be either spontaneous (no known cause) or induced (caused by specific environmental agents). What are some environmental agents that could increase the rates of genetic mutations among humans today? What types of mutations have the potential to be the most significant from an evolutionary perspective?
Answer:
Explanation:
Mutations happen spontaneously. The rate of mutation can be increased by environmental factors such as UV radiation , X-rays, gamma rays and certain types of chemicals such as bromine. These are some factor that can increase the rate of mutation
The classic example of evolutionary change in humans is the hemoglobin mutation named HbS that makes red blood cells take on a curved, sickle-like shape. With one copy, it confers resistance to malaria, but with two copies, it causes the illness of sickle-cell anemia. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.
Explanation:
Look the Mutations happen spontaneosly.So this means that this can increased by the enviromental factors such as Uv radiation, The X-rays, The Gamma Rays, and for last one the certain types of chemicals such as a bromine.These are some factors that increase the rate of the mutation.
So and here is the answer that you was looking for your answer was What are some environmental agents that could increase the rates of genetic mutations among humans today? well im here for teach you and told you or explain you whatever you wanted to call ir im here for teach you The evolutionary change that are in humans is that thing how is called? yes the Hemogoblin and you will say what is that thing why i want to know what is Hemogoblin Well you have to know that that think the hemogoblin is a mutation names "HBS" that makes the red blood cells it's for that reason that is important the "HBS" but there is the bad thing about the hemogoblin it makes the Anemia that is one of the terrible things that can happen to you ok?. Look they are good and bad thing about the Hemogoblin Im going to leave you some good and bad things about the hemogoblin: (But there are things that you have to know first the normal hemogoblin is in your DNA and in your DNA it's called G A G and it has too the C T C in your RNA it's called G A G and finally it nakes the GLU The GLU it's the normal Protein, but the hemogoblin can mutate the cell can get sick and the letters that are like This G A G those are going to change:
C T C They going to change like this:
(mutated)--- -- G T G
C A T (The RNA alsi change) G U G

\/
Val
(Original No mutated)---- G A G
C T C
G A G

(GLU)
The GLU is the Original Protein but the Val is the mutated Protein.
Now im going to say good and Bad thing about the Hemogoblin.
Good Things
N1:It creates the Blood cells
N2:Lactose Tolerance
N3-and also the Hemogoblin includes the HIV that is a resistance
Bad things about the Hemogoblin
N1-One of the most bad things of the hemogoblin is the Anemia that is the worst things as i say that can happen to you
and that's all you have to know

Which label identifies the part of the ATP molecule that changes when energy is released in the cells of all living
things?
B
Р P Р
A
A
B
C
Answer: Respiration
Explanation:
Cellular respiration is the process by which nutrients such as glucose are broken down using oxygen to generate energy in the form of ATP, that is used to drive cellular processes.
ATP consists of an adenosine molecule bonded to three phosphate groups in a row. Energy from cellular respiration is stored in the bond between the 2nd and 3rd phosphate groups of ATP.
When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.
If a man is color blind (an X-linked trait), how did he get this condition?
He got it from either his mom or his dad.
He got it from both his mom and his dad.
He got it from his dad.
He got it from his mom.
Answer:
He got it from his mom.
Explanation:
An X-linked trait means it is transmitted on the X chromosome.
Females have two X chromosomes (XX), and males have one X and one Y chromosome (XY).
Males get their Y chromosome from their dad, and X chromosome from their mom.
Therefore, the man inherited the colorblindness trait (X chromosome) from his mom
