3(a). Diagram 3 shows some processes that involve the changes in the
state of matter. Choose the processes that release heat.*
Answer:
C
D
Explanation:
The processes of freezing sublimation releases heat to environment.
Freezing is a phase change by which a liquid changes to solid.
Sublimation is a phase change in which a gas changes to solid.
Phase changes by which a substance returns back to the state of orderliness involves a loss of heat. Sublimation is can be from solid to gas or gas to solid. In the process from gas to solid, heat is released. But from solid to gas, heat is absorbed.Which statement about sister chromatids is true? One sister chromatid is inherited from each parent.

If 100 mice are bred, how many red eyed white mice would you expect?
Answer:
6
Explanation:
In this scenario, black fur (F) is dominant to white fur (f) and black eyes (E) are dominant to red eyes (e). So in this case you would be looking for all lowercase letters in the punnet square, which would only be 1 mouse with white fur and red eyes (ff ee), and since there are 16 potential genotypes for offspring and only 1 that would be white with red eyes, you would divide 1 by 16 and get 0.0625, then you would multiply 0.0625 by 100 (total number of mice) and you would get 6.25. since you can't really have .25 of a mouse (that would be kind of gross) you round down and get 6, the closest answer.

Water is found in many compounds such as blood, saliva, sweat because of which property of water? 6.)Which property of water causes water to form drops? 7.)Which property of water helps maintain extreme temperature changes in an area? 8.) What happens to hydrogen bonds when water turns to ice? 9.) Why doesn't water break down fat? 10.)Which property of water causes surface tension? Cohesion, Adhesion, High heat capacity, high heat vaporization and polarity
Answer:
1. polarity
2. hydrogen bonding
3. High heat capacity
4. Adhesion
5. polarity
6. surface tension
7. high heat vaporization
8. hydrogen bonds form a rigid and stable network
9. Water is a polar substance and fat is a nonpolar substance.
10. Cohesion
Explanation:
Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.
The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.
High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.
When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does not interact with fat because like dissolves like.
In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

Mitochondria require glucose to convert ADP to ATP. Which of the following statements describes how ADP is converted into ATP?
A. ADP loses a phosphate group which stores energy for use by the cell.
B. ADP gains a phosphate group which stores energy for use by the cell.
C. ADP loses a phosphate group which releases energy for use by the cell.
D. ADP gains a phosphate group which releases energy for use by the cell.
Answer:
B. ADP gains a phosphate group which stores energy for use by the cell.
Explanation:
ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy-producing structures called mitochondria.
The statement that describes how ADP is converted into ATP is as follows:
ADP gains a phosphate group which stores energy for use by the cell.Thus, the correct option is B.
What is ATP?ATP stands for Adenosine triphosphate. It may be defined as an organic compound that delivers energy to operate many processes in living cells, such as condensate dissolution, muscle contraction, nerve impulse propagation, and chemical synthesis.
ATP is considered a high-energy compound that furnishes immediate energy to the cell for metabolic activities.
ADP gets converted into ATP by gaining one phosphate group which is the most potent high-energy phosphate. This conversion of ADP to ATP generally takes place in the cytoplasm or in the membrane-bound cell organelle known as mitochondria.
Therefore, the correct option for this question is B.

____________________ is the process by which a cell makes a copy of the DNA in its nucleus.
A Replication
B Restoration
C Reduction
D Reproduction
[tex]\huge\boxed{Option A}[/tex]
_____________________________________REPLICATION---------------------------------------------------------------------------------------------Definition:DNA replication is the process by which a double-stranded molecule of a DNA is replicated(copied) to produce two morphologically and chemically identical DNA molecules.
__________________________________________________Why is it Important:Replication is a very important process for the living organism, because in a cell division, the two new daughter cells are produced which must contain the same genetic information or the DNA just like the parent cell. It cant be less or more than the parent cell.
__________________________________________________Steps of Replication:Replication occurs in three major steps,
1- the opening of the double helix and separation of the DNA strands,
2- the priming of the template strand.
3- the assembly of the new DNA segment.

Explanation:
Use scientific reasoning to explain why, in general, it makes sense that the lion population is taking longer to recover than the herbivore populations.
To scientifically answer the question using scientific reasoning, explaining generally why it makes sense that the lion population is taking longer to recover than the herbivore populations is that;
The herbivore populations have enough food in the ecosystem,this food is in the form of flora,and this food they get keep their energy flowing and also has a way of ensuring their high recovery rates.
Then looking at the lion population,on the contrary,they have to depend on feeding on smaller animals this is because the larger animals reproduce at a smaller pace, and lions with a smaller prey,lions don't get enough and adequate food/nutrition for themselves and also for their pride of lions,this ascertains the fact that lion population take a longer time to recover than it's counterparts which is the herbivores.

If all chloroplasts were removed from all living things, which substances
would no longer be produced?
Answer: Hope this helps!
Explanation:
In the process of photosynthesis sunlight is absorbed by the chloroplasts to make sugar. Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die. Without chloroplasts, plants would not be able to get their energy from the sun and would cease to survive, leaving us without food.
HIV can remain latent for several years and not cause any symptoms in its host. What viral reproduction cycle is occurring during this latency period? What viral reproduction cycle is occurring once a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection?
Answer:
The lytic cycle.
Explanation:
HIV is a retrovirus that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.
When there is a triggering event, this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery. Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.
