The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.

Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.

What are Skeletal muscles?

Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.

Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement.

Photosynthesis is a means of converting light energy to chemical energy. Explain what this statement means.

Answers

Answer:

photosynthesis, the process by which green plants and certain

other organisms transform light energy into chemical energy .

During photosynthesis in green plants, light energy is captured

and used to convert water, carbon dioxide, and minerals into

oxygen and energy-rich organic compounds.

also

During the process of photosynthesis, light penetrates the

cell and passes into the chloroplast. The light energy is

intercepted by chlorophyll molecules on the granal stacks.

Some of the light energy is converted to chemical energy.

During this process, a phosphate is added to a molecule to

cause the formation of ATP(Adenosine triphosphate)

Let's take a short look at photosynthesis before moving on to this topic.

It is an exergonic, light-dependent, biological, oxidoreductive, energy-yielding process. Where sugars or (CH2O)n are produced energetically by reducing CO2.

Although Co2 is essentially prevalent in nature, it does not break down into sugars since the reaction is thermodynamically possible.

Right after sunlight strikes the surface of the leaf, there are these little components known as reaction centers or energy harvesting cores, which are surrounded by antenna complexes. These antenna complexes are normally composed of chl a, chl b, xanthophyll, carotenoid, etc.

Here, the antenna complexes serve as filters, allowing just the necessary amount of flux to depart the outershelled electron of the chlorophyll molecule via energy activation states (of different kinds).

As the pigment system activates the chlorophyll molecule, the energy from the light is now transferred to chemo potential energy, which is subsequently employed in the process to oxidize the water molecule by the Kok clock mechanism.

Now this is an rather interesting cycle having multiple energy states, from Ground (SO) to maximum (S4) notice that the energy was first required to move on to next step in intermediates but as soon as it reached S4 or max state it oxidized water and this energy is actually enough to reduce Carbon di Oxide to sugar.

(Attachment #1)

If I'm not incorrect, the conversion works like this.

(Attachment #2)

As a result, it needs to be activated gradually in order to build up enough energy to pass the energy barrier.

NOTE:

As you can see, plants don't purposefully create oxygen, but why do they continue to do so? It does this because its primary goal is to turn sugar into oxygen, which it then converts into water that actually vaporizes while keeping the system cool.

Some animals that are scavengers can eat bacteria-laden meat that would harm humans. Which of the following best explains why these bacteria would harm a human, but not a scavenger?

The scavenger's immune system is strong enough to fight off bacterial infections before it produces toxins and damages tissues.
Only human cells have the complementary receptors that bind to surface molecules found on the bacteria.
Antibodies found in the blood of the scavenger destroy the bacteria as soon as they enter the bloodstream.
The pH and temperature environment in the human encourages more bacterial growth and colonization.

Answers

The scavenger's immune system is strong enough to fight off bacterial infections before it produces toxins and damages tissues. Thus, option "A" is correct.

How, explain your answer briefly?

Animals that feed on meat might have an immune system adapted to it and strong enough to prevent bacterial infections before it produces toxins and damages tissues.

Some of these animals (beetles) spray the rotting meat with an antimicrobial substance produced by their own organism, before starting to eat.

Other animals, however, consume rotten meat and attack bacteria with stomach acid that is ten times more acidic than our stomach acid, which can eliminate a large part of bacteria, before they cause problems. However, some bacteria can survive and cause serious problems if we eat these animals.

Thus, option "A" is correct.

Abscisic acid

Abscisic acid serves as an antagonist to Gibberellic acid. It is also known as the stress hormone as it helps by increasing the plant-tolerance to various types of stress.

[tex]\underline{\color{yellow}{hope \: its \: help \: you}}[/tex]

Plant hormones, also known as phytohormones, regulate growth by influencing cell division, elongation, differentiation, and various physiological responses in plants. These hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene.

Plants regulate their growth in size through the action of plant hormones, also known as phytohormones. These are chemical messengers produced by various parts of the plant, such as the roots, stems, leaves, and flowers.

There are several types of plant hormones, each with specific roles in growth regulation:

Auxins: These hormones are responsible for cell elongation and differentiation. They promote growth by increasing the flexibility of cell walls, allowing cells to elongate. Auxins are also involved in tropisms, which are growth responses to external stimuli like light (phototropism) or gravity (gravitropism).

Cytokinins: Cytokinins promote cell division and growth in areas such as roots, shoots, and fruits. They play a role in controlling the balance between shoot and root growth.

Gibberellins: Gibberellins are involved in stem elongation, seed germination, and flowering. They stimulate cell division and elongation, leading to increased plant height and size.

Abscisic Acid (ABA): ABA is often called the "stress hormone" because it regulates responses to stress conditions like drought, cold, and salinity. during adverse conditions.

Ethylene: Ethylene is a gas that regulates fruit ripening, senescence (aging), and responses to mechanical stress. It plays a role in processes like leaf abscission (shedding) and root growth inhibition.

Thus, plant hormones, also called phytohormones, control growth in plants by affecting cell division, elongation, differentiation, and a variety of physiological responses.

The pressure in mmHg of a 0.025 mole sample of CO2 at 350 k in a 2.00L container is 273.6 mmHg.

How to calculate pressure?

The pressure of a gas can be calculated using the following expression:

PV = nRT

Where;

P = pressureV = volumen = number of molesR = gas law constantT = temperature

P × 2 = 0.025 × 0.0821 × 350
