Answer:
the pulse or the temperature of the body
Answer:
If it grows and develops, uses energy, reproduces, is made of cells, responds to its environment, and adapts to its environment, it's living. A non-living object will not conform to all of these, only one or multiple of these qualities.
10. Use the theory of evolution to explain the observation that there are no tuskless males in the
park. WHY do males retain their tusks, when 50% of females lost them.
Type Here
Based on the theory of evolution, poaching of males for their tusk exacted a pressure on the elephant population which made more tuskless males to survive more than males with tucks as a result of natural selection.
Also, tucklessness as a trait is sex-linked, this explains why 50% of females lost their tusks why the males retain theirs.
Recall:
The theory of evolution describes the change that occur overtime through natural selection, whereby, offspring that are "fitter" are reproduced.Those that lack the fitness to survive produce fewer offspring than will survive.Male elephants are known to have tusks. However, poaching of elephants with tusks have exacted the pressure of natural selection on the population of elephants in the park.
The few tuskless males that are left surviving therefore produce more offspring as they pass the gene of tucklessness to their offspring. Over a long time, more tuckless males emerge while males with tusks will become almost non-existence as a result of natural selection.
A study showed that most females elephants have no incisors which suggests that the trait for tucklessness is sex-linked. This explains why 50% of the females lost their tusks and males retain theirs.
In summary, based on the theory of evolution, poaching of males for their tusk exacted a pressure on the elephant population which made more tuskless males to survive more than males with tucks as a result of natural selection.
Also, tucklessness as a trait is sex-linked, this explains why 50% of females lost their tusks why the males retain theirs.

If a more concentrated initial solution of sodium bicarbonate was used in beaker C, would it require more or less bicarbonate to neutralize the acid? Why?
Answer:
It would require less bicarbonate to neutralize the acid.
Explanation:
Sodium bicarbonate NaHCO3 is a, partly soluble sodium salt that decomposes in water to form a weakly basic buffer solution. It dissociates in water resulting in bicarbonate anions HCO− , sodium ions Na+ and H+.
2 NaHCO3(s) → Na2CO3(s) + CO2(g) + H2O(g)
Buffer solutions exist in equilibrium. In a solution with a strong acid and the conjugate base react, while the other carbonate ions dissociate to form carbonic acid, shifting the equilibrium of the solution back towards a balanced state.
HA ⇄ H+ + A-
Due to its buffering ability i.e. how well it maintains equilibrium, less bicarbonate would need to be added later on to neutralize the acid.
Less quantity of bicarbonate is needed for the neutralization of acidic solution.
Function of bicarbonatesIt require less bicarbonate to neutralize the acid because of its concentrated solution. If a more concentrated solution of sodium bicarbonate is used to neutralize the acid, lower quantity of it will be enough to neutralize it. Sodium Bicarbonate acts as a buffer which is commonly used for maintaining the pH of the solution.
Effect of BufferIt acts as a base when it is put in the acidic solution so helps in neutralizing the solution so we can conclude that less quantity of bicarbonate is needed for the neutralization of acidic solution.

Assuming DNA is replicated correctly (so there are no mutations),
in which of the scenarios below would the gametes produced all
be genetically identical?
Answer:
None of the choices would lead to all identical gametes.
Explanation:
Gametes are sex cells produced by sexually reproducing organims via a process of cell division called MEIOSIS. Meiosis is a cell division process which produces four (4) daughter cells (gametes), which are genetically different from the parent cell.
The difference in genetical content is as a result of a process unique to only meiosis called CROSSING-OVER OR RECOMBINATION. This process ensures that the genetic content of the gametes are altered. Hence, since gamete formation is done via meiosis, none of the scenarios in the option will lead to all identical gametes.

CO2
ATP
NADH
FADH2
ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.
Glycolysis is the metabolic pathway by which glucose is degraded up to two pyruvate molecules, while energy is produced in the form of ATP and NADH.
It takes place in a series of nine reactions, each catalyzed by a specific enzyme, to form two molecules of pyruvic acid, with the production of ATP.The Krebs cycle produces the release of acetyl-CoA resulting in the formation of an acid with six carbon atoms, citric acid.
A series of sequential reactions then occur, each mediated by a specific enzyme.In one of the reactions of the cycle, a molecule of ATP is produced, this molecule as an energy intermediate can take energy in catabolic reactions or give it up in anabolic reactions.Therefore, we can conclude that ATP is a product of glycolysis, pyruvate processing, and the citric acid cycle.

What does dilation, and therefore increased permeability, of the capillaries during the inflammatory response allow to happen
Answer:
During the inflammatory reaction and cytokine / cell diffusion, a chemical compound called nitric oxide, known as NO, is released. This chemical compound increases the permeability of the vessels, that is, the separation between the endothelial cells of the vessels to promote diffusion, inflammation and diapedesis.
Explanation:
Another factor that promotes permeability of the vessels are pro-inflammatory cytokines and chemicals released by antigen-presenting cells.

Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water

4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.
The diploid number of chromosomes in a species is always what
A diploid cell always contains two complete sets of chromosomes, which is described as 2n.
What is a diploid cell?Two complete sets of chromosomes are present in a diploid cell. The majority of human cells are diploid, with 23 chromosomal pairs totaling 46 chromosomes. This consists of a pair of sex chromosomes and 22 pairs of autosomes. The mother and father each contributed one copy of each pair of chromosomes to the individual.
Through the process of mitosis, diploid cells replicate and maintain the same number of chromosomes by making a copy of each chromosome and dividing their DNA equally among their daughter cells.
Blood cells, skin cells, and muscle cells are examples of diploid cells. These cells are called somatic cells. Different organisms have different numbers of chromosomes.
