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).

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.

Answer:
A
Explanation:
Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.
Why water is considered as actual renewable?Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.
Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.
Therefore, Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.

Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Describe how this process has played out in the maintenance of the sickle-cell trait. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Adult humans capable of digesting lactose were selected, thereby this phenotypic trait became common in dairy consuming societies
Explanation:
From the first moment after birth, babies can digest lactose in milk because they produce lactase, which is an enzyme capable of hydrolyzing lactose into glucose and galactose. In human societies that non consume milk products, the level of the lactase enzyme abruptly decreases during the first years of life due to the inactivation of the gene encoding this enzyme (i.e., lactase gene). However, in dairy consuming societies, a genetic mutation in the lactase gene that appeared among early cattle-raising people in Europe was selected, nowadays, this mutation is mostly present (i.e., in a higher frequency) in these societies, thereby adult people is generally adapted to consume lactose-based products.
In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) with a larger nonpolar side chain (e.g., Leu, Ile, Phe, Trp) in the mutant, result in significant destabilization and misfolding of the mutant. What feature of the protein core explains this observation? Why would such a mutation prevent a protein from folding properly? Match the items in the left column to the appropriate blanks in the sentences on the right.
Explanation:
we are required to fill in the blank spaces in the attachment.
protein side chains are non polar. so the first answer is non polar. These side chains are hydrophobic in nature. so the second blank is hydrophobic. Non polar substances are known to have large number of van der waal forces. the third answer is large and the fourth is vanderwaals contact. the protein core destabilizes only when there is a weakening of vanderwaals contact which brings about mutation.
dear user your answer should look like this:
Interactions of non polar side chains in protein sequence lead to the formation of a tightly packed hydrophobic core. This core is stabilized by a large number of vanderwaals contact. When a mutation occurs, it destabilizes the protein core and weakens vanderwaals contact leading to misfolding
this DNA strand consists of eight pairs of nitrogenous bases. how many different sequence of eight bases can you make? explain your answer.
Answer:
In the sequence of 8, it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.

Capillaries pass oxygen and waste between blood and cells.
Red blood cells fight disease.
People with type O blood can receive AB blood donations.
The left ventricle controls the heartbeat.
Answer: Capillaries pass oxygen and waste between blood and cells.
Explanation: Capillaries are very thin-walled tubes that connect the arteries to the veins. The walls of these tubes are only one cell thick. Capillaries are found everywhere in the body. These thin tubes allow the food, oxygen, and waste to move between the bloodstream and cells. Waste products pass into capillaries and are carried by the veins to be disposed of in other parts of the body. Capillaries are the only blood vessels thin enough for materials to pass back and forth between cells and blood.
Blood Capillaries pass oxygen and waste between blood and cells. Thus option A is correct.
What are the function of blood capillaries?Capillaries are small type of blood vessels where a single red blood cell can barely fit in them.
They involve in the connection of arteries and veins, facilitate the exchange of certain elements between blood and tissues.
They involve in exchange of oxygen, nutrients, and waste between blood and tissues by two major process called passive diffusion and pinocytosis.
In passive diffusion the movement of a substance from the region of higher concentration to the region of lower concentration occur.
In Pinocytosis, intake of small molecules by the cell of the body like fats and proteins.
The capillaries wall are composed up of endothelium which is a thin cell layer called and surrounded by another thin layer called a basement membrane.
Thus option A is correct.

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.
