Answer:

Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...

Explanation:

Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.

in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

Answer:

Living things can only come from living things.

Cells come from pre-existing cells.

Explanation:

Rudolf Virchow a german physicist, biologist and many more, In 1855 Vproposed that cells come from pre-existing based on his observations in exact words 'Omnis cellula e cellula', which translates into all cells arise from pre-existing cells.

He also said the living things come from living things and do not arise from nonliving things or matter. His discoveries made possible the cell theory

Answer:

the amount of carbon in the cycle can increase or decrease based on the number of factories present.

Explanation:

In the carbon cycle, carbon is exchange along many different forms on earth.  Carbon is the main component of biological compounds, and it is released from organisms when they die or when fossil fuels are burned, hence, the diagram demonstrates this.

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

Answer:

A. inherit genetic instructions passed down from the same parents.

These animals are not related because they do not inherit genetic instructions passed down from the same parents. The correct option is A.

The transmission of traits and otherwise information through one generation of individuals or cells to the next is referred to as inheritance.

Inheritance can occur through one of two mechanisms: genetic inheritance or epigenetic inheritance.

Deoxyribonucleic acid is another name for DNA. It is the genetic structure that is in charge of storing information.

A nitrogen base, sugar, and phosphate backbone make up DNA. Inheritance occurs when genetic information is passed from a parent to a child, and thus from one generation to the next.

A gene pair's two alleles are inherited, one from each parent. Alleles interact with one another in various ways. These are referred to as inheritance patterns.

Thus, the correct option is A.
