Answer:
Inhibition of the activity of photosystem II (PSII) under strong light is referred to as photoinhibition. This phenomenon is due to an imbalance between the rate of photodamage to PSII and the rate of the repair of damaged PSII.

Which two classes of biomolecules function in energy storage?
Answer:
Carbohydrates perform many functions in the cell. They form the structural elements of plants (cellulose), they function as intermediate energy storage for the body (glycogen) as well as quick energy (glucose), and perform many 'packaging and shipping' functions in the cell by serving as chemical markers.
Explanation:
The equations for photosynthesis and cellular respiration are shown below.
Photosynthesis
6C0, + 6H 0 -CH2O + 602
Cellular respiration
CH,+02 - CO2 + H2O
Which statement below best describes how the two are related?
A
The products of one reaction are the reactants of the other reaction.
B
Water is the only compound both reactions have in common.
с
The two reactions are exactly the same as one another.
D
Both reactions are carried out in the cells of heterotrophs.
Answer: A
Explanation:
The process of formation of the food by trapping the sunlight with the help of chloroplast is called photosynthesis. The reactant used in the process is carbon dioxide and water.
The oxidation of glucose in the presence of oxygen to obtain energy is called respiration. There are two types of respiration. These are as follows:-
AerobicAnaerobicBoth processes are very important for living beings, as these reactions are interconnected to each other.
Hence, the correct option is A that is the products of one reaction are the reactants of the other reaction because the glucose formed in the photosynthesis is used in respiration.

What determines whether a star will end its life cycle as a black hole or neutron star or as a white dwarf?
Answer:
Where a star ends up at the end of its life depends on the mass it was born with. Stars that have a lot of mass may end their lives as black holes or neutron stars. A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf.
The initial mass of the star with which it was born will determine how the star will end its life cycle.
What are black holes, neutron stars, and white dwarfs?
Black holes are regions in space with an extremely high pull of gravitational force which cannot even be escaped by light. Black holes are formed when the central core of a dying star collapses in itself.
Neutron stars on the other hand are extremely dense dead stars. Neutron stars are extremely bright objects, unlike black holes. Black holes are extremely dark because they trap any surrounding light while neutron stars emit light.
The massive stars in the universe end up as neutron stars or black holes. A star that has a low or medium mass ends up as a white dwarf.
A white dwarf is a dying star with a mass comparable to the mass of our sun but a size comparable to the size of the earth. Thus they have high mass and low dimensions.
Therefore, the factor that determines what a star will end up as is its mass when it was born.

12. A baby crawfish has a long tail. Its mother has a long tail while its father has a
short tail. Which of these statements explains why the baby has a long tail?
Answer:
Due to the presence of dominant allele.
Explanation:
The long tail feature comes to the offspring from their mother due to the presence of dominant allele. The dominant allele appears in the shape and structure of the offspring as compared to recessive allele which hide in the structure. The long tail appears in the structure of the baby crawfish so we can say that it is a dominant allele that transfer from the female parent into the offspring. In the offspring, some traits are transferred from father and some from mother.
Answer:
The baby crawfish inherited one copy of the gene for tail length from its mother and one copy from its father. Those genes connect together to make its long tail.

Answer:
Either C or B
Explanation:
The letter C in the diagram represents the location which pumps blood to the lungs for oxygenation.
How many types of blood circulation are found?There are two types of blood circulation:
Pulmonary circulation: It is the route via which pulmonary artery transports the right atrium's deoxygenated blood to the lungs for oxygenation.The oxygenated blood through pulmonary vein is poured back into the right atrium.Systemic circulation: It is the conduit through which oxygenated blood from the right ventricle travels to the body's other organs before being returned to the right atrium by the superior and inferior vena cava.Which blood vessel transports deoxygenated blood to lungs?Pulmonary artery transports deoxygenated blood to the lungs for oxygenation from right ventricle.

Throughout the day, activities in the liver, kidneys, and endocrine glands undergo large changes. Body temperature, blood pressure, and amino acid levels also shift from hour to hour. In fact, people tend to be more energetic and alert when these and other activities are at their highest point once a day. This is a description of Group of answer choices
Answer:
Circadian rhythms.
Explanation:
Stimulus in biology can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). All living organisms (both plants and animals) respond to changes in their environment and as such an appropriate reaction or response is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
Since both plants and animals respond to environmental stimuli, it simply means that, these living organisms have physiological cycles referred to as circadian rhythms.
Circadian rhythms is a natural internal process that controls the physical, mental, and behavioral changes in living organisms such as the sleep-wake cycle. The circadian rhythm is simply the internal body "24 hour" clock.
For example, there are large changes in the activities that happens with respect to the organs such as kidney, liver and endocrine glands within the body of living organisms throughout the day. Also, they experience timely shift in blood pressure, amino acid levels, body temperature, metabolism, etc.
Hence, living organisms are usually more energetic and at alert when the aforementioned activities and others are at their highest point once a day as a result of circadian rhythms.

adaptive features of Earthworm
here's your answer..
The adaptive features of Earthworm include streamlined body with no antennae or arms. The body of this organism is divided into segments.
What are the adaptive features?Adaptation can be defined as a state of the physical or the behavioral characteristics of an organism which helps them to survive better in the surrounding environment. Adaptation is essential for the survival of organisms in the new environment. These adaptations help the characteristics to become a part of the genetic makeup of the organisms.
An earthworm is a streamlined body organism with no antennae or fins or any arms or legs. The streamlined shape of the body is an adaptation to living in the narrow burrows which are present underground and the need to move easily through the soil. An earthworm has circular muscles which surround each body segment in the organism.

B.groundwater rises to the surface.
C.new crust is formed along the boundary.
D.oceanic plates slide beneath continental plates.
E.overlying, adjacent plates are pulled apart.
Overlying, adjacent plates are pulled apart when magma convection currents flow away from one another.
What is magma conventions?Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.Hence, option E is correct.
