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"
Answer:
Species

Explanation:
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.We are a carbon-based life form. List three properties of carbon that make it an ideal element
from which to construct a wide variety of complex molecules.
Answer:
Carbon can form four covalent bonds because it needs four electrons to fill its valence shell. Carbon-based molecules can vary in the number of carbon atoms.

Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.
Remember:
• Materials that mealworms use (arrows going in) are reactants in chemical changes
• Materials that mealworm produce (arrows going out) are products of chemical changes
When mealworms eat, chemical changes take place inside the mealworms. Chemical changes rearrange atoms. Bonds are broken in reactants. And new bonds are formed in the products.
Evidence of a chemical reaction includes a color or temperature change. Evidence of a chemical reaction can also be a gas or solid product made.
I think when a mealworm takes in_____
Level 4 responses should show potato/food arrows entering the mealworm, feces (and possibly urine) arrows leaving the mealworm and CO2 arrows leaving the mealworm.
Level 2 or 3 responses may show a variety of forms of matter without focusing specifically on molecules containing carbon atoms.
Energy Change: Explain your ideas about energy changes that are taking place inside the mealworms.
Level 4 responses should describe chemical energy moving from the potato into the mealworm and possibly chemical energy in the feces leaving the mealworm.
Level 2 or 3 responses may show a variety of forms of energy without focusing specifically on molecules containing high energy carbon bonds.
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.

Why would it be important to understand what controls the number and types of species in an ecosystem?
•THERE’S ALSO OTHER QUESTIONS IN THE PIC (if you could answer them it would be appreciated)
Answer:The short film Some Animals Are More Equal than Others: Trophic Cascades and Keystone Species opens by asking
two fundamental questions in ecology: “What determines how many species live in a given place? Or how large
can each population grow?” The film then describes the pioneering experiments by Robert Paine and James Estes,
in the 1960s and 1970s, which started to address them. Paine’s experiments on the coast of Washington state
showed that the starfish is a keystone species, having a disproportionately large impact on its ecosystem relative
to its abundance. Estes and colleague John Palmisano discovered that the kelp forests of the North Pacific are
indirectly regulated by sea otters, which feed on sea urchins that consume kelp. The presence or absence of sea
otters causes a cascade of direct and indirect effects down the food chain, which in turn affect the structure of
the ecosystem. These early experiments inspired countless others on keystone species and trophic cascades in
ecosystems throughout the world.
