Explanation:

plz give me brainiest

Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.

Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.

The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.

If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.

Therefore, the absence of essential amino acids limits muscular growth and repair.

Cyanide interrupts the electron transporter chain. Pyruvate concentration DOES NOT CHANGE. NADH concentration INCREASES in the matrix, and H+ concentration DECREASES in the intermembrane space.

-----------------------------------

Let us firts make a quick revision of aerobic respiration.

Through cellular respiration, cells degrade organic compounds and produce energy.

Aerobic respiration takes place in three steps:

1)  Glycolysis is the first step of cellular respiration. It occurs in the cytoplasm, and its final product is Pyruvate.

2) The Krebs cycle takes place in the mitochondria matrix.

3) The electron transporter chain is placed in the internal mitochondrial membrane.

                                              *******************

We already know that cyanide affects the electron transporter chain. So, let us focus on its functioning under normal conditions and under the cyanide effect.

⇒  Under normal conditions,

• ATP is produced at the end of the electron transporter chain.

• The electron transporter chain constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.

• Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.

• Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport.

• NADH and FADH2 provide electrons to the chain.

• While electrons move along the chain, complexes I, III, and IV pump protons to the intermembrane space.

• At the end of the chain, water molecules and ATP are produced.  

⇒  Under cyanide effect,

• Ion cyanide inhibits cellular respiration.

• Cyanide binds to the ferric ion of cytochrome oxidase.

• Cyanide-ferric binding inactivates the enzyme and blocks electron transference.

• The chain is interrupted. Hence,

• Since muscles do not get to have ATP as a source of energy, they weaken.

• The interruption of the electron transporter chain produces an anaerobic state that could be culminating.

                                        *************************

Now, let us answer the question

Since Pyruvate is produced in the cytoplasm, it is not affected by cyanide. Remember that cyanide only affects the electron transporter chain.

Since NADH provides electrons to the chain, and Cyanide interrupts electron transport, there is an accumulation of NADH molecules in the matrix.

Since the electron transporter chain is interrupted, no electrons are being carried, and no protons are being pumped to the intermembrane space.

Answer:

Mitosis plays an important part in the life cycle of most living things, though to varying extents. In unicellular organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell. In multicellular organisms, mitosis produces more cells for growth and repair.

Answer: Natural cloning also occurs in animal organisms during processes such as budding (offspring grows out of the body of the parent), fragmentation (the body of the parent breaks into distinct pieces, each of which can produce an offspring), and parthenogenesis. In humans and other mammals, the formation of identical twins is a type of natural cloning.

Answer:

Oxygen makes up about one-fifth the volume of Earth'­s atmosphere today, and is a central element of life as we know it.

But that wasn'­t always the case. Oxygen, although always present in compounds in Earth'­s interior, atmosphere, and oceans, did not begin to accumulate in the atmosphere as oxygen gas (O2) until well into the planet'­s history. What the atmosphere was like prior to oxygen'­s rise is a puzzle that Earth scientists have only begun to piece together.

Earth coalesced a little more than 4.5 billion years ago from bits of cosmic debris. Liquid oceans existed on the planet almost from the beginning, although in all likelihood they were repeatedly vaporized by the massive meteorites that regularly clobbered the planet during its first 700 million years of existence. Things had settled down by 3.8 billion years ago, when the first rocks that formed under water appear in the geologic record. (They exist in what is now southwest Greenland.)

If Earth had water, it must have had an atmosphere, and if it had an atmosphere, it must have had a climate. What was Earth'­s early atmosphere made of? Nitrogen (N2), certainly. Nitrogen makes up the bulk of today'­s atmosphere and likely has been around since the beginning. Water vapor (H2O), probably from volcanic emissions. Carbon dioxide (CO2), also emitted by volcanic eruptions, which were plentiful at that time. And methane (CH4), generated inside the Earth and possibly also by methane-producing microbes that thrived on and in the seafloor, as they do today.

Carbon dioxide, water vapor, and methane played an important role in Earth'­s subsequent development. Four billion years ago, the Sun was 30 percent dimmer, and therefore colder, than it is today. Under such conditions, Earth'­s water should have been frozen, yet clearly it wasn'­t. The water vapor, carbon dioxide, and methane acted as greenhouse gases, trapping heat and insulating the early Earth during a critical period in its development.

Of oxygen, meanwhile, the early atmosphere held barely a trace. What did exist likely formed when solar radiation split airborne molecules of water (H2O) into hydrogen (H2) and oxygen (O2). Hydrogen, a lightweight gas, would have risen above the atmosphere and slowly been lost to space. The heavier oxygen gas, left behind, would have quickly reacted with atmospheric gases such as methane or with minerals on Earth'­s surface and been drawn out of the atmosphere and back into the crust and mantle. Oxygen could only begin to accumulate in the atmosphere if it was being produced faster than it was being removed'—in other words, if something else was also producing it.

That something was life. Although the fossil evidence is sketchy, methane-producing microbes may have inhabited Earth as long ago as 3.8 billion years. By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun'­s energy to convert carbon dioxide and water into food with oxygen gas as a waste product. They lived in shallow seas, protected from full exposure to the Sun'­s harmful radiation. (To learn more about these organisms and the fossil evidence for them, watch the accompanying video "Early Fossil Life.")
