Answer: Gene
Explanation:
Genes are the segment of DNA that are responsible for a particular trait in the body rising from their ability to code only a particular type of protein.
Genes are acquired from both parents during conception and are therefore the smallest unit in heredity.
Genes determine everything from the color of our eyes to the shape of our toes and are therefore very important in building life.

1)How do populations of invasive species continue to grow, and disrupt ecosystems?
2)What are natural factors that can cause the introduction of invasive species?
3)How do most invasive species introductions happen?
Answer:
Due to absence of predators.
Explanation:
The populations of invasive species grow rapidly because of the absence of predators that can control its population as as result, it disrupt the whole ecosystem. Change of climatic conditions of the area where they live causes them to migrate from its original place to a new region where the invasive species have no predators to control its population but mostly humans are responsible for the introduction of invasive species. In most cases, the introduction of invasive species happen due to human activities.

Images that you see in your peripheral vision are not as sharp as those directly in front of you because: there is a higher concentration of cone cells in the center of the retina in an area called the fovea. there are fewer rod cells in areas of the retina where images from the periphery are focused. the lens cannot focus images well on areas of the retina where images from the periphery are projected. the rod cells in the periphery are sensitive to blue and green light only.
Answer:
The correct answer is ''there is a higher concentration of cone cells in the center of the retina in an area called the fovea.''
Explanation:
The fovea, the central area of the macula, is the area of the retina where the vision of details is the most accurate. It is located in the extension of the optic axis of the eye. The fovea is populated only with cones, and allows us the best optical resolution, the field of vision that occurs around the central focus / outside the center of the field of vision (fovea) is known as peripheral vision, it is related to the location and recognition of the visual information that is around the object on which we fix our attention. That is, it is one that uses the peripheral area of the retina and that gives rise to the field of vision that surrounds the point where the sight is fixed / allows us to see the environment that surrounds us in a general way.

Explanation:
I have never heard of volcanoes on Mercury, and there couldn't be water since it would evaporate immediately. This means it either creates its own heat or it's because it's so close to the sun. Now, if you think about it, we don't create our own heat, we only trap it. So it is safe to assume that it's so hot because it's so close. Hope this helps!
Answer:
The answer is B because it's the closest to the sun

If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called --
Answer:
Hypertonic solution
Explanation:
A hypertonic solution is where the concentration outside of the cell is greater when compared to the inside of the cell.
If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called - hypotonic solution.
Hypotonic solution is the one that contains more concentration as compared to the concentration in the cytoplasm of cells. It means that a solution contains more water as compared to the water within the cell.
molecules move from their higher concentration to their lower concentrationIt is called osmosisWater molecules always try to balance their concentration on both sides.When an animal cell, such as a red blood cell, gets water to the hypotonic solution, it swells.Thus, If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called - hypotonic solution.

Explanation:
Humans produce the enzyme amylase. This enzyme breaks down starch, a
complex carbohydrate found in many food sources (e.g. potatoes, breads).
Explain why the human digestive system is unable to use amylase to break down
the complex carbohydrate cellulose, which is also found in some foods (such as
celery).
Explanation:
We lack the enzyme cellulase which is the enzyme required to break down cellulose.
Base on the given information, human can produce the enzyme amylase, but cannot produce the appropriate enzymes that is able to breakdown the beta acetal linkages that exist in cellulose.
Enzymes serves as biological protein, and it is needed in the body to carry out specific functions.
Human posses amylase which made it possible to breaks down starch that is contained in many carbohydrate food that we eat.
We can conclude that human doesn't have the enzymes that that act on complex cellulose contain in found like celery.

How many trophic levels do most food webs have? Why? Relate your answer to the appropriate law of thermodynamics
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.

what are the many forms of energy? how is energy either potential of kinetic
Answer:
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
You need energy to do any work, which is why the ability to do any work is energy. Read that again. Potential and kinetic energy are two forms of energy that can be converted into each other. Potential energy can be converted to kinetic energy and vice versa.

Mitosis results in two diploid cells that have the same genetic makeup. Meiosis results in four haploid cells that are all genetically different from each other.
What is Mitosis?A kind of cell division known as mitosis occurs when a single cell (the mother) divides into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.
Mitosis is used in the vast majority of cell divisions that take place in your body. Mitosis fills an organism's body with cells during development and growth, and it replaces old, worn-out cells with new ones over the course of an organism's existence.
Mitotic divisions are a type of reproduction for single-celled eukaryotes like yeast, resulting in the generation of new members of the population.
Therefore, Mitosis results in two diploid cells that have the same genetic makeup. Meiosis results in four haploid cells that are all genetically different from each other.
