Photo system 1 = Light

This is the presence of sunlight, whereby Chlorophyll is used to trap sunlight energy to split water molecules into hydrogen ions and hydroxyl ions also NADP is reduced by the addition of hydrogen to form NADH

Photo system II: Dark stage

It happens when there is abscence of light where by CO2 ingested by plants react with hydrogen atoms from the light stage to form the Emperial Formula of simple sugar. Also Hydroxyl ions (OH -) is furtherly broken-down to oxygen & molecules.

Photosynthesis is the process in which green plant manufacturer their food in the presence of Sunlight ND chlorophyll. Where CO2 (Carbon [iv] oxide) and water (H2O)

During the day time

Explanation:

Diurnal animals are active during the day time and are inactive at night.

A wide range of animals fall into this category. Examples are human beings, chipmunks, goats, sheep etc.

As the sunrises, diurnal animals begins to get up and as the sun set, their activities reduces and they become inactive.

The answer is March and September

Both Northern and Southern Hemispheres receive the same amount of energy from the sun in March and September

It is a phenomenon that is used to describe a period during which both the Southern and Northern Hemispheres receive the same amount of energy from the sun.

During this period, the declination of the sun is at the equator. thus, both sides of the Hemisphere receive an equal proportion of the sun both in duration and energy magnitude.

Equinoxes occur twice in a year - March and September

The chemical equation which best represent an aerobic respiration reaction is: D. Glucose + Oxygen -----> Carbon Dioxide + Water + ATP.

An aerobic reaction can be defined as both biological and chemical processes that generally takes place in the presence of oxygen.

This ultimately implies that, an aerobic reaction requires oxygen before it can occur.

On a related note, an aerobic respiration reaction refers to how the body of a living organism uses oxygen such as;

Basically, the two main reactants (inputs) reactants for an aerobic respiration reaction include:

Conversely, the end products of an aerobic respiration reaction are:

In conclusion, the chemical equation which best represent an aerobic respiration reaction is:

           [tex]Glucose + Oxygen ---> Carbon \;Dioxide + Water + ATP[/tex]

The equation that best represents the aerobic respiration reaction is: Glucose+ oxygen→ Carbon Dioxide+ Water+ ATP.

In this equation, glucose (C6H12O6) is oxidized in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy. This is the process of aerobic respiration, which occurs in the mitochondria of cells to generate energy for cellular activities.

Vigorous breath is the organic cycle where food glucose is changed over into energy within the sight of oxygen. The majority of mammals, birds, humans, and plants use this kind of respiration.

Answer:

a) true

b) false

c) true

d) false

e) false

Explanation:

hi im taking ap biology and it's not my best subject but here r my reasonings:

a) inhibitors decrease the rate of reactions in general, so i would assume that increasing the number of inhibitors would decrease the overall rate or reaction

b) it's false bc allosteric inhibitors bind to a place on the enzyme other than the active site. u can see on the figures that the blue-green allosteric inhibitor is in a place other than the active site at the top

c) because allosteric inhibitors bind to a different place on the enzyme, this often results in an formational change in the enzyme. bc of this change in shape of the enzyme, this can rly prevent the substrate from binding to the active site

d) i dont think adding a competitive inhibitor will increase the number of products bc competitive inhibitors decrease the reaction rate by blocking substrates from binding to the active site :/

e) false bc competitive inhibitors do not bind to the substrates; they bind to the active sites, thus blocking the substrate from entering the active site. u can see this in the blue-green square at the top figures

Answer:

space between gas molecules

Explanation:

as the altitude increases the air density decrease because of weaker gravity and these led to more distant of air molecule  and the space between gas is increased

As the altitude increases the air density decrease because of weaker gravity and these led to more distance between air molecule and the space between gas is increased.

The answer is option D.

As the height increases, the pressure increases. - As the height increases, the air density increases. - Air pressure and congestion are very low at sea level. - Heavy air is more pressurized than small dense air.

The gravitational pull between the earth and the air atoms is much larger than those distant molecules - they are heavier - pull them closer and increase the force (energy per unit) between them.

7.) Wavelengths of 430nm(blue) and 662nm(red). ( It reflects green light strongly so it appears green to us. :) )

8.) Glucose is used by plants for energy and to make other substances like cellulose and starch. (Cellulose is used in building cell walls.)

9.) Animals either eat plants to obtain chemical energy in the form of glucose or they eat other animals that ate plants. So, energy moves from the Sun to plants to animals. Animals also use oxygen released by the plants to breathe.

The earliest vertebrates that use to resembled are hagfish and lived more than 500 million years ago. As other classes of fish appeared, they evolved traits such as a complete vertebral column, jaws, and a bony endoskeleton.

Amphibians were the first tetrapod vertebrates as well as the first vertebrates to live on land. Segmentation is a part of characteristic of the body plans of various goup of animals including the annelids, and recently developed vertebrates. There are three different segmental systems origin in development of the vertebrates that are - the somites, the rhombomeres and the pharyngeal arches.

There are several benefits of the segmentation development and these are the different type of anatomical and morphological developments are helps in facilitate specific functions are led by the segmented body.

The Paraxial mesoderm also have segmentation that helps in lateral movement and It has been also helps  in the consistent and fast interaction or communication in the neuronal system.

eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?

(a)The roots change into branches, and the branches turn into roots.

(b)The roots grow toward the force of gravity, and the shoots grow away.

(c)The plant will become a smaller version of a mature plant.

(d)Roots always grow toward the dark, and shoots grow toward the light.

Two options appear to be correct here: options B and D

Explanation:

Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b

Answer:

the relationship between stress and strain that a particular material displays . it's unique for each material . it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress  in a typical stress-strain curve ,  the breaking strength is less than the ultimate strength

Explanation:

The typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.

A typical stress-strain curve has several segments, including the elastic region, which represents the stiffness of the material, and the plastic region, which represents the point at which the material begins to permanently deform. Necking: a reduction in cross-section; ultimate strength, then a material's ability to deform until it reaches its ultimate strength, and so on.

Hence, the typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.
