which of these should be reportable reasons to protect public health?
a) Skin cancer
b) Heart disease
c) HIV
d) Diabetes
Answers
Among the following HIV should be reportable reasons to protect public health.
HIV impairs the body's defenses against infections and leads to AIDS. Contact with contaminated blood, or fluids might result in the virus being spread. Flu-like symptoms including fever, sore throat, and exhaustion might appear a few weeks after HIV infection. Until AIDS develops, the illness is typically asymptomatic. Fatigue, fever, night sweats, and weight loss are a few of the signs and symptoms of AIDS. Despite the fact that there is no known treatment for AIDS, diligent adherence to anti-retroviral therapy (ART) can significantly decrease the disease's progression, avoid complications and secondary infections, and lengthen life. One of the primary tactics used in the prevention and control of HIV/AIDS around the world is the dissemination of information and awareness about HIV.

Answers
The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.
DNA replicationThe biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:
cell division during tissue development and repair, and it also guarantees that each new cell gets a copy of the DNA.A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.
These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

Other things being equal, what is a potential disadvantage of an enzyme having a very high affinity for its substrate?.
Answers
Since the ES complex would be in a "energy trough," the activation energy for the transition state would be quite high.
What is enzyme?Tight enzyme substrate binding will lower the reaction's forward rate constant.A forward reaction's activation energy will increase when an enzyme's affinity for its substrate is high.Because the enzyme-substrate complex will be located in a deep energy well, it will be more stable.In contrast to the situation where the substrate-enzyme binding is weaker, a tight binding of the substrate to the enzyme will alter the amounts of free substrate and free enzyme. This little modification won't have much of an impact on the reaction kinetics because the substrate concentration is often higher than the enzyme concentration.It is unlikely that tight binding would result in the active site being altered. Since the enzyme is significantly bigger than the substrate, it is unlikely that it will change shape.Learn more about enzyme here:

explain in steps how a tree trunk gets wider
Answers
Answer:
The first thing that determines the thickness of a tree trunk is the species. Some kinds of trees just naturally have a different trunk thickness than others.
The second thing might be the environment. A tree that is experiencing all factors - sun, water, soil, minerals - at an optimum level is going to grow faster, taller, stronger, and thicker than the same species in a less-optimum environment.
A third factor is time. As time passes, the tree trunk increases in diameter - thus a tree that is 50 years old will have a much thicker trunk than one that is 5 year old.
And, in case you’re wondering why or how tree trunks increase in thickness at all, there is a thin layer of cells all around the trunk of a tree, like a sheet that lives under the bark. This layer is called the cambium layer which makes new living tissue for the tree (called phloem and xylem) every year. As the year’s growth comes to an end, the living tissue dies and is pushed outward to appear as bark by the new year’s sheet of cambium cells, which is bigger than the previous year’s - hence, the increase in diameter of the tree every year.

During and after photosynthesis, energy changes from one form to another in a series of steps. Which step related to this energy transformation occurs second?
Answers
The step that relates to the energy transformation in photosynthesis is respiration.
What is respiration?Respiration is the process whereby the chemical energy locked up in carbohydrates is unlocked into another energy form that is usable to living organisms.
In other words, chemical energy in carbohydrates is converted to ATP. This process can take place with (aerobic respiration) or without (anaerobic respiration) oxygen.
Carbohydrates are primarily generated from photosynthesis by green plants.

An angle measures 176 more than the measure of its of its supplementary angle.what is the measure of each
angle
Answers
Based on the definition of supplementary angles, the angles are: 2° and 178°.
What are Supplementary Angles?Angles that are supplementary have a sum that equals 180 degrees.
Let the measure of the supplement be x.
The other angle would be: (x + 176)
Therefore, we would have:
x + (x + 176) = 180
2x + 176 = 180
2x = 180 - 176
2x = 4
x = 2
One of the angles is, 2°
Second angle = x + 176 = 2 + 176 = 178°

Answers
The size of the barred owl population in that ecosystem would decrease.
Reduced biodiversity, or the variety and richness of various kinds of animals and plants in a given setting, is the main consequence of habitat degradation. An animal's population rapidly declines as it draws closer to extinction when it loses the habitat or natural home that it requires to survive.A proportional drop in the number of animals inhabiting a given landscape is predicted to result from habitat destruction. One might anticipate a drop in animal abundance of 50%, for instance, if 50% of a forest environment that supports a big population of an animal is destroyed.similarly, If all of the large, dead trees were removed from the ecosystem, The size of the barred owl population in that ecosystem would decrease.learn more about ecosystem here:
