Answer:
Permineralization.
Explanation:
Permineralization is a way of fossilization in which mineral deposits form internal casts of organisms, therefore, turning them into fossils.
What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
The body would synthesize the amino acids.
Muscle growth and repair would be limited.
Stored protein would break down.
The formation of proteins would increase.
Answer:
Muscle growth and repair would be limited
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.
What are the essential amino acids?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.

describe the significance of mitosis for unicellular algae.
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.

Is using fossil fuels in generating electricity better or using renewable energy? why?
Answer:
Explanation:
Using renewable energy will always be better than fossil fuels.
This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.

How has the poison changed the concentration of pyruvate, NADH and intermembrane H+ in Jared’s cells?
Answer:
no change, increase, decrease
Explanation:
I just did it
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,
NADH and FADH2 stop providing electrons, complexes I, II, and IV stop pumping protons to the intermembrane space, there is no oxygen consumption and no ATP production.• 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
Pyruvate concentration ⇒ NO CHANGESince Pyruvate is produced in the cytoplasm, it is not affected by cyanide. Remember that cyanide only affects the electron transporter chain.
NADH concentration ⇒ INCREASE
Since NADH provides electrons to the chain, and Cyanide interrupts electron transport, there is an accumulation of NADH molecules in the matrix.
Intermembrane H+ concentration ⇒ DECREASE
Since the electron transporter chain is interrupted, no electrons are being carried, and no protons are being pumped to the intermembrane space.

Describe the natural process that creates a human clone.
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.

What two groups are represented in archaeopteryx?
Please help
Answer:
The species of Archaeopteryx is lithographica and siemensii
Explanation:
Fun fact: Archaeopteryx is a combination of two ancient Greek words: archaīos, meaning "ancient," and ptéryx, meaning "feather" or "wing."
Archaeopteryx has long been thought to be the earliest known bird and a transitional form between birds and reptiles.
What are Archaeopteryx?Many consider Archaeopteryx, which lived approximately 150 million years ago, to be the first bird.
It is actually a transitional species between the birds we see in our backyards and predatory dinosaurs like Deinonychus.
Many features of Archaeopteryx, such as teeth and a long tail, indicate that it evolved from comparatively tiny carnivorous dinosaurs.
It also has a wishbone, a breastbone, hollow thin-walled bones, air sacs in the backbones, and feathers, as do nonavian coelurosaurian relatives of birds.
Archaeopteryx was thought to be the first recognized bird and a transitional form between birds and reptiles for a long time.
Thus, the two groups that are represented in archaeopteryx are birds and reptiles.
