Answer:
When the cloud of gas which formed the solar system fell inwards to form the solar system, it had net angular momentum. ... The cloud that formed the solar system had angular momentum which was deposited into the velocities of planets and other bodies in orbits around the Sun (as well as the Sun's rotation).
Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This keeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?
Answer:
Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.
Explanation:
The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells.
Normal cells VS mutant cellsNormal cells show response to contact inhibition when they come into contact with other cells, so they stop moving and dividing.
While on the other hand, The mutated (cancer) cells show the evidence that they do not respond to contact inhibition because there is no stopping of division of the cells so we can conclude that no stopping of division occurs which is the evidence that the cancer cells show no response to contact inhibition.

2.What is the adaptation that is beneficial to organisms in the Desert Sand environment?
Answer:
Dense hair and thick skin.
Thin skin and Nocturnal behavior.
Explanation:
Dense hair and thick skin are the adaptation that is beneficial to organisms that is present in the environmental condition of Mountain Rock because on Mountain Rock, the temperature is very low so organisms needs something which make them warm, while on the other hand, thin skin and Nocturnal behavior are the adaptations that is beneficial to organisms in the Desert Sand environment because temperature is very hot.
The cell membrane is made up of a lipid bilayer as shown in the model. Which of the following describes the structure and function of the cell membrane?
56 points!!!!!!
Answer:
The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell
Explanation:
Cell membrane is selectively permeable in nature. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell, which is a water-like environment and hydrophobic tails form an oily layer inside the membrane. Thus, correct option is A.
What is Plasma Membrane?Plasma membrane is also known as the cell membrane. It is found in all types of cells that separates the interior of the cell from the outside environment. In bacterial and plant cells, a cell wall is also found which covers the cell membrane.
The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. Plasma membrane is selectively permeable in nature, it allows only some material to pass through it while blocks other material from entering through it.
The portions of the integral membrane protein found inside membrane are hydrophobic, while portions which are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic in nature. Molecules that are hydrophobic can easily pass through the plasma membrane while hydrophilic particles cannot pass through the membrane easily.
Therefore, correct option is A.

You added 20 g of NaCl to 100 g of water. What is the percent by mass of the solute?
Answer: We are given:
Mass of solvent (water) = 100 grams
Mass of solute (NaCl) = 20 grams
Mass of the Solution:
Mass of Solution = Mass of Solute + mass of Solvent
100 + 20 = 120 grams
Mass Percent of NaCl:
We know that
mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100
replacing the variables
Mass% of NaCl = (20 / 120)*100
Mass% of NaCl = 100 / 6
Mass% of NaCl = 16.67%

What is the phase change from gas to liquid?
A. Sublimation
B. Condensation
C. Vaporization
D. Transpiration
Answer:
Condensation
Explanation:
Condensation is the phase change from gas to liquid. For example, water vapor condenses when you are taking a shower because wet spots show up on a mirror after taking a shower.
Answer:
Condensation
Explanation:
Sublimation is when a solid turns into a gas. Condensation is when water in the air collects to form droplets that gather on a surface/object. Vaporization is when a liquid forms into a gas. Transpiration is a thing in plants where water transfers throughout the plant.
which statement describes what happens with ATP during glycolysis?
A) more ATP is produced than is used
B) glycolysis splits ATP
C) more ATP is used than is produced
D) glycolysis does not make any ATP
Answer:
A. more ATP is produced than used
Explanation:
Regulation of glycolysis
Several steps in glycolysis are regulated, but the most important control point is the third step of the pathway, which is catalyzed by an enzyme called phosphofructokinase (PFK). This reaction is the first committed step, making PFK a central target for regulation of the glycolysis pathway as a whole^1
1
start superscript, 1, end superscript.
PFK is regulated by ATP, an ADP derivative called AMP, and citrate, as well as some other molecules we won't discuss here.
ATP. ATP is a negative regulator of PFK, which makes sense: if there is already plenty of ATP in the cell, glycolysis does not need to make more.
AMP. Adenosine monophosphate (AMP) is a positive regulator of PFK. When a cell is very low on ATP, it will start squeezing more ATP out of ADP molecules by converting them to ATP and AMP (ADP + ADP \rightarrow→right arrow ATP + AMP). High levels of AMP mean that the cell is starved for energy, and that glycolysis must run quickly to replenish ATP^2

This process is a set of metabolic reactions that occur inside cells to convert the biochemical energy obtained from food into a chemical compound called adenosine triphosphate (ATP). Metabolism define as the set of chemical reactions carried out to maintain the living state of cells in an organism which can be divided into two categories:

Developing a new vaccine takes about 5-10 years. So how is it possible to develope Corona vaccine so quickly?
Answer:
vaccines were designed by using new technologies (i.e., RNA-based vaccines and adenovirus-based vaccines)
Explanation:
RNA-based vaccines are vaccines based on the delivery of specific messenger RNA (mRNA) sequences that are capable of encoding only one viral protein, thereby preventing the complete viral cycle/replication. Subsequently, this protein is recognized by the immune system that generates memory immunity by synthesizing specific antibodies against this protein (in this case, the spike S protein). On the other hand, adenovirus-based vaccines are vaccines designed by inserting a transgene cassette into an adenovirus which is used as vector to produce one specific viral protein inside the host. Like mRNA vaccines, this antigenic viral protein is then recognized by the immune system in order to produce antibodies against a defined protein epitope, thereby producing memory immunity.
You want to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%). How much of each will he have to mix together? Show your work for full credit.
Answer:
To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed
Explanation:
Using the Pearson’s Square calculations:
1. Subtract across the diagonal:
a. 18% - 12% = 6 parts soybean meal
b. 18% - 22% = 4 parts corn
2. Sum the parts:
a. 6 parts soybean meal + 4 parts corn = 10 totalparts
3. Divide each part by the total to calculate the percentage of each feed to include in the ration:
a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal
b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn
So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),
60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal
40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn
