Predation is when a predator feeds on another organism, which is referred to as the predator's prey.
True
False
Answer:
True
Explanation:
Predation is another mechanism in which species interact with each other. Predation is when a predator organism feeds on another living organism or organisms, known as prey. The predator always lowers the prey's fitness. Also, a predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

Which of these statements concerning lipids is not true?
A. Lipids are substances that dissolve in nonpolar solvents.
B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.
C. Fats, phospholipids, and steroids are lipids.
D. The building blocks of fats (triglycerides) are fatty acids and glycerol.
Answer:
B
Explanation:
Unsaturated fatty acids have double bonds. Fatty acids that contain only single covalent bonds between the carbon atoms are called saturated.
The statement: "B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated." is NOT TRUE.
Lipids include the following group of compounds:
FatsOilsPhospholipids SteroidsWaxesThe above compounds are nonpolar hydrocarbon compounds that are insoluble in water. This means they can hardly dissolve in water.
Fatty acids, which is an example of lipids, can either be saturated or unsaturated. If it is saturated, it means they contain only single covalent bond among the carbon atoms while it is unsaturated if a double bond exist in the chain of the molecule.
A fatty acid that contains only single covalent bonds cannot be called "unsaturated." It is rather "saturated."
Therefore, the statement concerning lipids that is not true is: B. A fatty acids that contains only single covalent bonds between the carbon atoms is called unsaturated.
An example of a saturated fatty acid is shown in the attachment below:

A group of students studied heat transfer by placing a hot block of metal into a Styrofoam cup of room temperature water what method of heat transfer with the student studying
Radiation
Convection
Conduction
Thermal energy
Answer: Thermal Energy
Explanation:
i worked it out tell me if im right
Method of heat transfer which is being studied by the student is thermal energy.
What is thermal energy?
Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.
Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.
These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy. There are 3 types of thermal energy 1) conduction 2) convection 3) radiation

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
What are the products for a single pyruvate molecule in the Krebs Cycle?
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.
Answer:
In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

What are two ways in which cells use the energy temporarily stored in ATP?
Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways
The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.
What is Active transport?
Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.
ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

Which of the following describes prophase of mitosis?
A. Chromosomes condense and nuclear membrane breates down.
B. Homologous chromosomes line up along the equator of the cell.
C. Cytoplasm divides as cell prepares to become two new cells.
D. Daughter chromosomes move toward opposite poles of the cell.
Answer:
Daughter chromosomes move toward opposite poles of the cell.
Explanation:
Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.
CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.
When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.

The Char gaff rule is all about the number of adenine is equal to the number of thymine and with that the number of cytosine is equal to the number of guanine. The correct answer is option B.
What are the types of bonds that are present in between these nitrogenous bases ?The kind of bonds that are present in these nitrogenous bases are hydrogen bonds. A binds with T with two hydrogen bonds and C binds with G through 3 hydrogen bonds.
It is all about that the number of purines is equal to the number of pyrimidines. The number of adenine molecule are present totally in equivalence to the number of thymine molecules.
