PLZZ HELP!!!!!
Ludmilka [50]

The correct answer is option C, that is, it prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.

The herbicide atrazine combines with the D1 protein and inhibits the binding of plastoquinone. By obstructing the binding of plastoquinone, the procedure of photosynthetic transfer of electron is disturbed, and thus, the production of ATP and NADPH in the chloroplast gets compromised.  

This leads to an incapacity to fix carbon dioxide and generate the nutrients required for the plant to live. The block in the transfer of electrons also results in an oxidative stress and the production of radicals that lead to brisk cellular destruction.

Hello,

I believe green water is more fertile. Green water<span> is the soil ​moisture from ​precipitation, ​used by plants ​via transpiration.​ It is part of ​the evapotranspiration​ ​flux in the ​hydrologic ​cycle. Blue water is just ground and surface water.

Draw a flowchart that explains how Tom’s nervous system controls his actions. As part of the flowchart, write one or two sentenc
Katarina [22]
<h2>Answer 1 with Explanation </h2>

The nervous system help the body to respond to different stimuli because its function is to coordinate with all the body parts. It has four primary functions that relate to the areas of the body in every human being for which the system handles information. The sensory function allows the body to collect information from outside or within the body.

<h2>Answer 2 with Explanation </h2>

Tom steps into the haunted house- the brain receives information from different parts of the brain and interprets it to generate the emotion of fear and then sends impulses to different parts of the body to trigger a flight response. Organisms that fear and make a flight response are more likely to survive. Later then the nervous system interprets the information to the brain through the spinal cord.

<h2>Answer 3 with Explanation </h2>

Tom feels his heart pumping and his breathing speed up because of the sympathetic nervous system stimulates adrenal glands that trigger and releases adrenaline which results in an increase in heart rate, blood pressure, and breathing rate. The integrative function is about how the collected information is being interpreted in Tom.

<h2>Answer 4 with Explanation </h2>

Tom jumps when he sees the costumed character. This is due to flight response in an individual, unleashes powerful hormones are released that affect the whole body from which signals are transferred to the brain and then it causes an involuntary jump in the muscles of the individual. The reasoning of this is that Tom's brain responses in a shock when he sees the character.

<h2>Answer 5 with Explanation </h2>

Tom runs out of the haunted house The reason of this is that Tom runs when the brain makes his muscles move by sending electrical signals to them through the nerves and this kind of involuntary actions happen really quickly so that the action takes place faster. At last, the nervous system helps to determine the motor function in which the effectors are able to respond.

What are the functions of the roots, stems, branches, leaves, flowers, and fruits in a plant?
Pachacha [2.7K]
Roots absorb nutrients and water from the soil, as well as keep the plant attached to the ground. Some plants also use the roots, to parasite other plants (ie, Mistletoe) or reproduction (Potatoes). 

Stems, transport water and nutried to the plants up reaches, sometimes they are important for protection, as they are covered in thorns or toxins.  

Branches sort of form the same function as stems, only they branch out from the stem.

Leaves, are where the plant conducts its metabolic photosynthetic processes. Sometimes the leaves are also important for protection (the thorns of cacti are actually leaves).

Flower, are useful for reporduction, giving out pollen and when combined with other pollen are turned into fruits.

Fruits are the protective object of the seed, and provide nutrition for the seed, a means of seed dispersion, and lastly protection from outside forces.

Choose THREE examples that correctly predict the effect of a change on the ecosystem.
topjm [15]

Answer:

The answer is option A "A decrease in the kangaroo rat population will cause a decrease in the coyote population"

Explanation:

Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.

Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
