ATP(adenosine tri-phosphate) stores energy between it's 2nd and 3rd phosphate groups. When the 3rd phosphate group is released ADP(adenosine mono-phosphate) is created and energy is being released. This molecule is important because it stores the energy from cellular respiration and most cellular processes require the energy released by ATP.

Explanation:

The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.

Parts of the nervous system includes:

--> Central Nervous System ( consists of the brain and spinal cord)

--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).

The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.

Let us assume that following:

S=distance

U=initial velocity

V=final velocity

A=acceleration

T=time taken

Given that:-

S=2.5 km

S=2.5×1000 mtr

S=2500 mtr

T=12 seconds

V=180km/hr

 =180×1000/3600 m/sec

V=50 mtr/sec

U=0 because in starting his car in rest position

Equation which use for calculations of acceleration,

S = UT + 1/2AT^2

2500 = 0×12 + 1/2A(12)^2

2500 = 0 + 1/2×A×144

2500 = 72×A

A = 2500/72

A = 34.72 m/sec^2

It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2

Answer:

Reverse carbon dioxide and glucose, and you should be good! In other words:

I hope this helps!

light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

Plants absorb water and carbon dioxide  from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.

Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.

Therefore, light energy where you have it and Move glucose to where carbon dioxide is and Move carbon dioxide to where glucose.

[tex]\huge\textbf{Cell Theory}[/tex]

the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,

It was corrected by the German pathologist  Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,

Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

[tex]\huge\textbf{Question:}[/tex]

These observations support the  point that cells could arise only by a division of pre-existing alive cells because in Flask 1 when there were no micro-organism present so there was no organisms found so no micro-organism arised, In flask 3 the S tube was used so no micro-organism could reach the meat thus there were no organism there which could divide to reproduce. The flask 2 was open, so the micro organisms reached the meat so they divided which means Cells can only arise by a division of pre-existing cells.

All these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms, and this explains the cell theory through all these experiments.

Cell theory is a fundamental concept in biology that describes the basic unit of life and its properties, and here in flask 1, if the meat is properly sealed and handled in a sterile environment, it is possible that no microorganisms could enter through it and explain that no growth is seen as no microbes are present. In flask 2, as the meat is open and exposed, it is more likely that microorganisms could be present and potentially grow. Microorganisms are ubiquitous in the environment and can be found in soil, water, air, and on surfaces such as countertops, utensils, and cutting boards. The use of an S tube could potentially reduce the amount of microorganisms that reach the meat due to the curvy path that is present in flask 3.

Hence, all these experiments explain that cells only form from preexisting cells, as microbes give rise to the synthesis of new organisms.

Answer:

Amino acids are the structural units (monomers) that make up proteins. They join together to form short polymer chains called peptides or longer chains called either polypeptides or proteins. These polymers are linear and unbranched, with each amino acid within the chain attached to two neighboring amino acids.

Answer:

•Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration  puts it back.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Cellular respiration:

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

In this way it release the carbon dioxide back into atmosphere.

It is something on which other elements depend. A test score, for instance, may be a dependent variable because it could vary based on a number of variables, including how much you studied. How much sleep you got the night before the test, and even how hungry you were.

The thing being measured in an experiment or assessed in a mathematical equation is the dependent variable. The term “the result variable” is sometimes used to describe the dependent variable.

Reliant Variable the measurable variable that is dependent on other measurable things. As a result of manipulating the independent variable or variables in an experiment, these variables should change.

Therefore, In an investigation, the result is a dependent variable whose value is affected by changes in the independent variable.

How do the strands separate during PCR? The DNA polymerase breaks the hydrogen bonds between the two strands. The primers separate the strands during the annealing step. The high heat of the denaturation step breaks the hydrogen bonds between the two strands.

The two things that can cause a DNA helix to separate into two strands during PCR are initiation and unwinding.

PCR is a polymerase chain reaction. The process is making more DNA sequences from a DNA sequence. The process is done in a PCR machine. The DNA template is put in the machine and a copy of the DNA is made.
