Answer:
The orbital eccentricity (or eccentricity) is a measure of how much an elliptical orbit is 'squashed'. ... Elliptical orbits with increasing eccentricity from e=0 (a circle) to e=0.95. For a fixed value of the semi-major axis, as the eccentricity increases, both the semi-minor axis and perihelion distance decrease. or
It is probably used because the more eccentric an ellipse is, the more its foci are 'off the center' of the ellipse. ... These orbits turned out to be ellipses with the sun at one of the focus points. In this context, the eccentricity of the ellipse indicates how far from circular these orbits are.

What is it called when a whale has died and rested in the bottom of the ocean to provide nutrients for other animals and the soil?
Answer:
Decomposition.
Explanation:
Decomposition is the process in which dead or organic matter is broken down over time into simpler organic and inorganic matter. A whale resting at the bottom of the ocean will provide food for animals and restore nitrogen to the soil. Overtime, the whale will no longer exist. This is an example of decomposition.

Which organelles must be present within a cell of a geranium
leaf for respiration and
photosynthesis to occur?
A) cell wall and vacuole
B) ribosome and nucleus
C) mitochondria and chloroplast
D) endoplasmic reticulum and cell membrane
Mitochondria and Chloroplast organelles must be present within a cell of a geranium leaf for respiration and photosynthesis to occur. So, the correct answer is (C).
What is Mitochondria?
A mitochondria is an organelle found in the cell of most eukaryotes such as animals plants and fungi and is a double membrane structure that uses aerobic respiration to generate ATP which is used as a source of chemical energy. Mitochondria are also known as the powerhouse of the cell.
The main role of mitochondria is oxidative phosphorylation in which it generates ATP by using the energy that is released during the oxidation of the food we eat. It uses ATP, the primary energy resource for most chemical, biochemical and physiological processes.
It is used in the process of photosynthesis and respiration along with chloroplast in the plants. it is also known as Chondriosome or sarcosome.
Thus, Mitochondria and Chloroplast organelles must be present within a cell of a geranium leaf for respiration and photosynthesis to occur. So, the correct answer is (C).

Which scenario would most likely result in the extinction of one or more species? The water temperature of a pond decreases slightly, and the members of the pond populations adapt to the change. The conditions are abnormally dry for one season in a desert, resulting in the deaths of a few members of a snake population. A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish. A new plant species begins growing in a forest, resulting in a new food resource for many animal populations.
Answer:
The scenario which would most likely result in the extinction of one or more species is A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
Explanation:
Among the four given scenario, one of the scenario would most likely result in the extinction of one or more species that is "A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish." The rest three does not implies about the extinction of the species.
A pond's water temperature decreases significantly, and the members of the population of the pond adjust to the transition. In this argument, depending on climatic and seasonal shifts, and on how a pond is used, the composition of pond water changes continuously. Good management aims at managing the composition in order to create the best conditions for the fish. In this case, the pond population will then alter their adaptations rather than disappear or become extinct.The conditions in the desert are abnormally dry for one season, resulting in the deaths of a few members of a population of snakes. For only one season, which is temporary, the abnormal condition persists in this case, resulting in the deaths of only certain snakes. Hence, because the dry state is temporary, the extinction of the snakes does not occur. A predatory fish is introduced into a lake, resulting in a drastic decline in smaller fish populations. This argument is right about the extinction of species as the predator fish will eventually consume all the small fishes and the small fish will slowly and gradually disappear and become extinct day by day.In a forest, a new plant species starts developing, resulting in a new food supply for many populations of animals. In this case, there will be no loss or extinction of organisms when new species are introduced, and it will ultimately result in the creation of new food sources and species.Hence, the answer is - A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.

Describe the effect of an enzyme on the activation energy in a chemical reaction.
Enzymes are biological catalyst meaning they speed up reactions. They do this by lowering the activation energy which results in bond breaking much faster, leading to a quicker chemical reaction.
In conclusion, enzymes speed up a chemical reaction by lowering the activation energy, resulting in a faster rate of reaction as bonds break quicker.
Hope this helps even though its quite simplified! :)

A new fat-burning pill for men is introduced. To test for effectiveness, 50 men are given the pill and 50 men are given a placebo. After 6 months, the men's body fat percentage is calculated. Identify the control group, the manipulated variable, and the responding variable. Explain how you can identify each.
Answer:
The correct answer is -
The control group - the group of men with a placebo pill,
The manipulated variable - fat burning pill,
The responding variable - men's body fat percentage
Explanation:
The control group of a study is a group that did not get the treatment or manipulated variable so the comparison between the experiment group and the control group can be found and see what are the difference. Here the group of subjects that receives no treatment but a placebo pill only is the control group.
The manipulated variable is the treatment or the manipulation that can cause the response in the subject here the fat burning pills are manipulated variable. The responding variable is the variable known as the dependent variable that is measured to see what effect on the subject occurred here the body fat is the responding variable.

Which of the following is a correct statement on the state of an enzyme at the conclusion of a chemical reaction ?
A( The enzymes is not changed by the chemical reaction.
B( The chemical reaction causes the enzyme to reduce in size
C( The products of the reaction never release themselves from the enzyme
D( The enzyme is dissolved by the substrate that covers it during the reaction.
Answer:
d
Explanation:
A correct statement on the state of an enzyme at the conclusion of a chemical reaction is: A. The enzymes is not changed by the chemical reaction.
An enzyme can be defined as a biological catalyst that typically speeds up (increases) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).
Hence, the rate of any chemical reaction is faster when its activation energy is decreased, reduced or lowered.
Furthermore, some of the characteristics associated with an enzyme include the following:
Enzyme structures (active site) are specific to the type of substrate they bond to.An enzyme may or may not require cofactors. The action of an enzyme in a chemical reaction may involve minerals.An enzyme can be used over and over i.e continuously, for different chemical reactions.Basically, an enzyme can be used continuously (over and over) because it is not changed by the chemical reaction.
In conclusion, an enzyme is unchanged by the chemical reaction it catalyzes (speeds up).

What is photosynthesis and chlorophyll?
Answer:
photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.
Hope this helps!
Have a great day! :)
