Answer:
The theory of Continental Drift suggest that hundreds of years ago all the continents were one big continent called Pangea. Soon these contintents split up created the places that we live today. This theory was introduced by Alfred Wegener. His colleges thought he was crazy, but later studies proved his impossible theory to be true. By the process of "sea floor spreading" the continents were then ripped apart and drifted to where they are today.
A recent clinical study demonstrated a possible connection between coffee consumption and heart health. The researchers performed
a 6-week trial with 191 individuals, all of whom were heavy coffee drinkers (average of 5 cups/day) prior to the experiment, but none of
whom were smokers. They divided the 191 participants into three groups: no coffee consumption, 1-3 cups/day, and 4 or more
cups/day. They measured blood levels of cholesterol and homocysteine as indicators of heart health Only the no-coffee group showed
a significant drop in both indicators. Previous studies had demonstrated that decreases of the magnitude observed in the no-coffee
group could cut the incidence of heart disease by 10-15%.
a) What is the problem/question being studied?
b) What is the hypothesis?
c) What is the experimental variable?
d) List the controls
e) What is being measured to test the hypothesis?
Answer:
The summary as per the issue is summarized in the following portion of the clarification.
Explanation:
(a)
The association regarding coffee intake and insulin sensitivity is being tested and the results. This procedure is intended to examine whether unnecessary coffee intake is positive or negative again for the heart. Or if there are any cardiovascular problems it may induce.(b)
The hypothesis seems to be the consequence of such a hypothesis. This illustrates inside such an outcome the association between the factors and response variable. It is stated to provide an understanding of the experiment's response.(c)
Any conditions that may be adjusted, calculated, or influenced during an analysis constitute variables. Three research variables have become primarily present. Variable autonomous, variable dependent including variable power. They are those variables that can only be modified in an experiment by a researcher. Independent variables are essentially the cause for the effect, as well as a shift of independent variables impacts the variables (dependent) accordingly.The independent variable throughout this analysis is the number of coffees, in which 3 categories are given separate amounts of cups of coffee. The researcher decides the coffee which should be offered to all the participants.(d)
Through an analysis, monitoring variables are those variables most of which are maintained stable. Variables under regulation throughout this experiment include body temperature, ambient moisture.(e)
To verify the theory, the ratio of cholesterol including homocysteine throughout the blood would be calculated. The theory indicates that a rise in cholesterol levels, as well as homocysteine levels, can be caused by increased coffee intake, thus raising their risk of cardiovascular diseases.Bruh please help.

Hello!!! Princess Sakura here ^^
Explanation:
Genetic variations is an advantage to a population because it allows them to adapt to their environment.
Example: The arctic fox has brown fur in the summer but in the winter it grows in white fur. That's because it needs to blend in with its surroundings.

What does “denature” mean in terms of protein structure?
Explanation:
Denaturation, in biology, process modifying the molecular structure of a protein. Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state.

Water molecules can stick to other water molecules through which type of
bond?
Covalent
lonic
Oxygen
Hydrogen
Answer:
Hydrogen Bonds
Explanation:
Hydrogen bonds allow for hydrogens to bond to each other. They are the strongest type of intermolecular bonds.
Hydrogen bonds are dipole-dipole, and when water molecules are close to each other, the hydrogen bonds form between the hydrogen atoms.
Answer:
hydrogen bonds
Explanation:
this type of bond allows hydrogen atoms to bond together.
How does a change in pH above or below optimal pH affect enzyme
function?
A. No change
B. Reaction happens faster
C. Enzyme dies
D. Enzyme denatures
Answer:
[tex]\boxed {\tt D. \ Enzyme \ denatures}[/tex]
Explanation:
Extreme temperatures or pH can denature enzymes.
Enzymes have a very special and specific shape that determines which substrate they can act on. If the pH changes too dramatically, then the peptide bonds holding the amino acids of the enzyme together break.
When the bonds break, the enzyme loses its shape and it cannot function anymore.
So, there is a change, the reaction doesn't happen faster or die. We can eliminate choices A, B, and C. The correct choice is D. enzyme denatures

What is the most important reason to control the conditions of an experiment?
O to make the experiment easier to repeat
O to reduce the amount of data that must be recorded
O because this is necessary for graphing the data
O because this is necessary for the data to be valid
Answer:
The answer would be the last choice, "because this is necessary for the data to be valid."
Explanation:
This is because in an experiment, things must be controlled or monitored in most ways; otherwise, the result of the experiment will be different from what it was meant to be. An experiment should be as exact as possible. If this is not possible, results may be unreliable.

photosynthesis?
Answer:
H2O+CO2 LIGHT sugars+O2
Explanation:
The equation (Carbon dioxide + water ⇒ Glucose + Oxygen) summarizes the process of photosynthesis correctly, as glucose is formed along with oxygen in photosynthesis. Thus, the correct option is A.
What is Photosynthesis?
Photosynthesis is the process of formation of carbohydrate (sugar) in the leaves of green plants. In this process, the solar energy from the sun is converted into chemical energy in the form of sugar. Here, the sunlight is trapped in the chlorophyll pigment present in the chloroplast.
The sunlight with chlorophyll converts carbon dioxide and water into glucose and oxygen, the glucose is used to produce energy through Cellular respiration and oxygen is used in the process of respiration.
Therefore, the correct option is A.

what are acquired traits why are the streets generally not inherited over generation explain
Answer:
Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.

how does Maritime Equatorial impact the areas that it is in? plzzzz help fast i will mark u branilist
Answer:
Explanation:
Air mass, in meteorology, large body of air having nearly uniform conditions of temperature and humidity at any given level of altitude. Such a mass has distinct boundaries and may extend hundreds or thousands of kilometres horizontally and sometimes as high as the top of the troposphere (about 10–18 km [6–11 miles] above the Earth’s surface). An air mass forms whenever the atmosphere remains in contact with a large, relatively uniform land or sea surface for a time sufficiently long to acquire the temperature and moisture properties of that surface. The Earth’s major air masses originate in polar or subtropical latitudes. The middle latitudes constitute essentially a zone of modification, interaction, and mixing of the polar and tropical air masses. Continental Polar (cP) air usually forms during the cold period of the year over extensive land areas such as central Asia and northern Canada. It is likely to be stable and is characteristically free of condensation forms. When heated or moistened from the ground with strong turbulence, this type of air mass develops limited convective stratocumulus cloud forms with scattered light rain or snow showers. In summer strong continental heating rapidly modifies the coolness and dryness of the cP air mass as it moves to lower latitudes. Daytime generation of cumulus clouds is the rule, but the upper-level stability of the air mass is usually such as to prevent rain showers. The continental Tropical (cT) air mass originates in arid or desert regions in the middle or lower latitudes, principally during the summer season. It is strongly heated in general, but its moisture content is so low that the intense dry convection normally fails to reach the condensation level. Of all the air masses, the cT is the most arid, and it sustains the belt of subtropical deserts worldwide. The maritime Tropical (mT) is the most important moisture-bearing and rain-producing air mass throughout the year. In winter it moves poleward and is cooled by the ground surface. Consequently, it is characterized by fog or low stratus or stratocumulus clouds, with drizzle and poor visibility. A steep lapse rate aloft in regions of cyclonic activity ensures the occurrence of heavy frontal and convective rains. In summer the characteristics of the mT air mass over the oceans and in zones of cyclonic activity are basically the same as in winter. Over warm continental areas, however, the air mass is strongly heated so that, instead of fog and low stratus clouds, widely scattered and locally heavy afternoon thunderstorms occur.
