Elephant tusks are either present or absent due to genetics, specifically the existence of key genes that regulate tusk growth. Environmental elements, however, can also affect the proportion of tuskless elephants in a population.
Elephants are frequently hunted down during conflicts or wars for their ivory tusks, which are highly sought-after on the illicit market. Over time, the population of elephants with tusks may decline as a result of this selective hunting of those with them.
The age range of 10 to 20 years old is essential because it coincides with the period of time when elephants usually begin to grow their tusks. Around the age of 6 to 8 years, young elephants may start developing their tusks, and by the time they are 10 to 20 years old, their tusks should typically be more noticeable and developed.
It is possible that many young elephants with developing tusks will be killed if a conflict or a period of rampant poaching takes place during this crucial time, which will reduce the number of tusked elephants in the population. After such a conflict or a period of heavy poaching, there can be a larger percentage of tuskless elephants between the ages of 10 and 20.
This theory makes the assumption that there was greater poaching or selective hunting occurring during the conflict, which would have a disproportionately negative effect on elephants with tusks. In order to provide a more comprehensive knowledge of the issue, additional examination of local conditions and data would be required. The individual situations and variables affecting elephant populations can differ.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. At the end of the experiment, there were 99/8 ounces of the solution remaining. How many ounces of solution did Mia start with? *
Given:
The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.
Remaining solution at the end of the experiment = [tex]\dfrac{99}{8}[/tex] ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.
Total decreased amount [tex]=\dfrac{9}{8}\times 5[/tex]
[tex]=\dfrac{45}{8}[/tex]
Initial amount = Remining amount + Decreased amount of solution.
[tex]x=\dfrac{99}{8}+\dfrac{45}{8}[/tex]
[tex]x=\dfrac{99+45}{8}[/tex]
[tex]x=\dfrac{144}{8}[/tex]
[tex]x=18[/tex]
Therefore, the initial amount of solution is 18 ounces.

What is the difference between reproduction and heredity?
Reproduction is the process of passing on traits, whereas heredity is the process of
producing offspring
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Reproduction always involves changes in inherited characteristics, whereas heredity
does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not
Answer:
Reproduction is the process of producing offspring, whereas heredity is the process
of passing on traits.
Explanation:
PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!
Reproduction generally means making copy of something, like giving birth/breeding, duplicating.
Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!
They definitely aren’t same!
Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.
What do you mean by heredity?Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.
Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.
Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

A student claims that a leaf is living, and a plastic leaf is nonliving. Which statement provides evidence to support the claim?
Answer:
The plastic leaf lacks cellular structure.
Explanation:
One of the buffers that contribute to pH stability in human blood is carbonic acid (H2CO3). Carbonic acid is a weak acid that, when placed in an aqueous solution, dissociates into a bicarbonate ion (HCO3-) and a hydrogen ion (H+).
Thus, H2CO3 = HCO3- + H+
If the pH of the blood increases, one would expect:
(A) a decrease in the concentration of HCO3- and an increase in the concentration of H+
(B) an increase in the concentration of H2CO3 and a decrease in the concentration of HCO3-
(C) a decrease in the concentration of H2CO3 and an increase in the concentration of HCO3-
(D) an increase in the concentration of HCO3- and a decrease in the concentration of OH-
(E) a decrease in the concentration of HCO3- and an increase in the concentration of both H2CO3 and H+.
I'm not sure if it is C or D
Answer:
The answer is "Option C".
Explanation:
In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.
The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood. It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.With respect to one another, galaxies have been found to be

What is the initial source of the energy in all food webs and food chains? Explain please
Answer:
The sun
Explanation:
The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.
The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.
What is the primary source of energy?The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.
The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Active transport uses ATP and does not require a carrier protein; facilitated diffusion does neither.
Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.
Answer:
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Explanation:
Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.

Why did some people think that there was evidence of intelligent life on Mars?

Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.
Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says National Aeronautics and Space Administration more like Never a straight answer.
Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.
Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.
There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:
Mars has some characteristics similar to planet Earth.Many rocks on Mars have organic molecules.There is evidence that the surface of Mars once had water about two thousand years ago.There is water at the poles of Mars.There are water flows on the planet's hot slopes that are resistant to freezing.With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.
