Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
Since, the options have not been given the question is incomplete the complete question is as follows:
Changing the shape or morphology of the mitochondrial inner membrane can change the efficiency of mitochondrial function.
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
A. Mitochondria will become more efficient because the inner mitochondrial membrane will become more permeable to ions.
B. Mitochondria will become more efficient because the total volume of the mitochondria will increase.
C. Mitochondria will become less efficient because the inner mitochondrial membrane will become less permeable to large molecules.
D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Answer: D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
Explanation:
Mitochondria is called the power house of the cell as it produces energy by the oxidation of food in the form of adenosine triphosphate or ATP. The inner mitochondrial membrane comprises of numerous folds which are called cristae which increases the surface area for the chemical reactions necessary for the production of energy. If the folding increases the surface area for energy production will decrease as the surface area for chemical reactions will decrease. Thus the efficiency of mitochondria will decrease.
If the mitochondrial inner membrane becomes flat or smooth surface then this also decreases the surface area for chemical respiration, thus in this case too the efficiency of mitochondria will decrease.
Metabolism is a term used to describe all the chemical processes that go on
continuously inside an organism to maintain life and the proper functioning of organs.
Examples include breathing, repairing cells and digesting food. These chemical processes
require

energy
diffusion and osmosis are both forms of
a. organelles
b. channel proteins
c. active transport
d. passive transport
Answer:
D
Explanation:
Diffusion and osmosis are both passive forms of transport because there is no energy need to transport something such as water from an area of high pressure, to an area of low pressure.
7. a) Protein molecules are the building blocks of the body. They are made up of long chain
amino acids. Draw the general structure of an amino acid. (1 points)
HINT: Think about the carboxyl group, amino group, and side chain
Answer:
....................
Explanation:
Except for water as well as fat, this same human species comprises essentially completely composed of protein.
Proteins are generally made up of some acids such as Amino, which have been tiny chemical compounds made up of either an alpha carbonyl group coupled to something like an amino group, a carboxylic acid group, another hydrogen ion, as well as a response to changes known as nothing more than a chain length.Muscles contain around 80% proteins, eliminating fluid, trying to make essential nutrients extremely vital for athletes.
Thus the above response is appropriate.

The surface of rivers freeze when the temperatures falls below freezing. However, the water underneath this layer of ice continues to flow. This phenomenon allows fishermen to fish through holes drilled in the ice the entire winter. Which property of water is the reason the river doesn't freeze completely?
Answer: Water retains its temperature for long.
Explanation:
The ice floats on the water of river as it is less denser then the liquid water. This causes ice to float on water. It protects the water at the bottom from freezing. The decrease in the temperature level can cause the death of the marine life by catching organisms in the ice. The floating of the ice insulates the water present beneath. So, the fish and other aquatic animals can survive and the fishermen can catch the fishes alive.
Answer:B hydrogen bonds expand during the freezing process
Explanation:
explain how the energy producing processes occurring in the cells of organisms drives the cycling of matter within an ecosystem
Answer:
The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon based organic molecules and release oxygen

Linnaeus developed two groups for classifying organisms: genus and .
Answer:
Species
Explanation:
Carl Linnaeus was a Swedish scientist who developed a formal system of naming organisms- bionnomial nomenclature
The first part of the name identifies the genus to which the species belongs, and the second part identifies the species within the genus.
For example the tiger is called "Panthera tigris". The species is tigris (tiger).
The genus is Panthera (which also includes the lion (Panthera. leo), the jaguar (Panthera onca), and the leopard (Panthera pardus). The species is "tigris"

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.hey can you help me with some questions
