The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.
A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A.
Potential energy is greatest at point D. Therefore, option C is correct.
What is potential energy?Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.
The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.
Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?
a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.
Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.
The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.
In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.
Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.
The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.
Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.
Answer:
Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
Explanation:
During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.
----------------------------------------------------------------------------------------------
During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.
ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.
ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.
The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.
These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).
ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.
Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.
Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .
The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.
During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.
Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.
The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.
Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

A. greenhouse effect
B. acid rain
C. radioactivity
D. extinction
Answer:
A. greenhouse effect
Explanation:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Climate change results from the shedding of gases like CO2 into the atmosphere where it can trap more heat.

Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
Explanation: is this good enough?
Answer:
Because its a sequence in which molecules can store their own energy and use it when needed such as in a chemical reaction , note that this is the main reason some molecules stay dormant during a chemical reaction and that is because they didn't use ATP
Explanation:
The principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ...

10. What are two examples of "typos" that happen when DNA is being copied?
Answer:
DNA “typos” cause variation
Explanation:
Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.
The "typos" that happen when DNA is being copied is mutations and variations.
What are mutations?A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Moreover, mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
Therefore, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA. They can be large scale, altering the structure of the chromosomes.

Answer:
Answer below
Explanation:
Cholesterol refers to a group of chemical compounds. A sterol is a kind of lipid, and cholesterol is one of them. All animal cells produce cholesterol, which is an important structural component of cell membranes. It is a yellowish crystalline solid when chemically separated.
a sterol-type molecule present in most human tissues. Cholesterol and its derivatives are key components of cell membranes and precursors of other steroid chemicals, but a high proportion of low-density lipoprotein in the blood (which delivers cholesterol to the tissues) is linked to a higher risk of coronary heart disease.
Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol you require.
