Answer:
It would be the cell theory
Cell theory is the basic concept of biology includes the idea that new cells can be produced only by the division of existing cells.
What is cell theory?In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
A component of the cell theory is that all living things are composed of one or more cells. A component of the cell theory is that the cell is the basic unit of life. A component of the cell theory is that all new cells arise from existing cells.
All known living things are made up of cells. The cell is structural & functional unit of all living things. All cells come from pre-existing cells by division. (Spontaneous Generation does not occur).

during which phase of the cell cycle does most cell growth occur
Cell growth occurs constantly throughout interphase. S phase is the time when all the cell's chromosomes are replicated so significant cell growth occurs here, but during both G1 and G2 cell growth occurs.
hope this helps
During the interphase of the cell cycle most cell growth takes place.
What is cell cycle?A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the maximum of its time in what is referred to as interphase, where it grows, reproduces its chromosomes, along with prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
The cell cycle's longest phase is interphase. This is the stage at which the cell undergoes and duplicates its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
Thus, the cell growth takes place in the interphase of the cell cycle, and the division takes place in the M-phase.

ey's Bell Jar...
Abstract
Background
Photosynthesis maintains aerobic life on Earth, and Joseph Priestly first
demonstrated this in his eighteenth-century bell jar experiments using mice and
mint plants. In order to demonstrate the fragility of life on Earth, Priestley's
experiment was recreated using a human subject placed within a modern-day
bell jar.
Methods
A single male subject was placed within a sealed, oxygen-depleted enclosure
(12.4% oxygen), which contained 274 Cz and C plants for a total of 48 h. A
combination of natural and artificial light was used to ensure continuous
photosynthesis during the experiment. Atmospheric gas composition within the
enclosure was recorded throughout the study, and physiological responses in the
subject were monitored.
Results
After 48 h, the oxygen concentration within the container had risen to 18.196, and
hypoxaemia in the subject was alleviated (arterial oxygen saturation rose from
86% at commencement of the experiment to 99% at its end). The concentration
of carbon dioxide rose to a maximum of 0.66% during the experiment.
Conclusions
This simple but unique experiment highlights the importance of plant life within
the Earth's ecosystem by demonstrating our dependence upon it to restore and
sustain an oxygen concentration that supports aerobic metabolism. Without the
presence of plants within the sealed enclosure, the concentration of oxygen
would have fallen, and carbon dioxide concentration would have risen to a point
at which human life could no longer be supported.

heyyyyy
Explanation:
An enzyme called glucocerebrosidase breaks down a glycolipid in the body known as glucocerebroside. However, in a genetic disease known as Gaucher’s disease, the body does not produce enough glucocerebrosidase. Therefore glucocerebroside can build up in the body and this can cause serious side effects such as anemia and swelling of the liver and spleen. Identify the substrate.
Answer:
glucocerebroside
Explanation:
The substrate is the substance being acted upon by the enzyme. The enzyme glucocerebrosidase breaks down glucocerebroside. Therefore, glucocerebroside is the substrate in this example.
The excretory system disposes waste through the stomach.
True or False?
Answer:
False.
Explanation:
Actually the stomach isn't part of the excretory system, it's part of the digestive system. The organs of the excretory system include the kidneys, large intestine, liver, skin, and lungs. The kidneys (also part of the urinary system) filter out blood from waste. The large intestine's job is to eliminate solid waste that remains after food is digested and water is extracted from the indigestible matter. The liver breaks down many substances in the blood, including toxins. Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. The lungs (also in the respiratory system) excrete some waste products, such as carbon dioxide and water.

The mountains of the Sierra Nevada play a role in the formation of desert in eastern California and Nevada.
What is this an example of?
Answer:
The correct answer would be - The lithosphere influences the atmosphere and biosphere .
Explanation:
The mountains of the Sierra Nevada play the role of a barrier that blocks the air or wind that brings the clouds filled with water to eastern California and Nevada as it can not pass the mountains and reach the other side of mountains which cause less or no rain to this region.
Rain is a very important aspect for the region to be less diverse in plants and animals as most of them require water but as it is described there is no or very little precipitation so it becomes desert.
This makes it an example of the lithosphere influences the atmosphere and biosphere .

Analysis of mitochondrial DNA can answer interesting and important questions. For which of the questions would analyzing mitochondrial DNA be futile?
Answer:
to identify the father of the individual
Explanation:
Mitochondrial DNA (mtDNA) is the circular DNA molecule found in mitochondria, which is an organelle responsible for cell respiration by converting chemical energy from foods to ATP by the process of cellular respiration. In humans, mtDNA consists of about 16,500 base pairs (bp) and encodes for 22 tRNAs, 2 rRNAs and 13 proteins. In most of the species, including humans, mtDNA is inherited from the mother (i.e., it is maternally inherited), and therefore mtDNA cannot be used to trace the patrilineal ancestry of a given person or population.
