Why do traits increase within a population over time

Answers

Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.

In your words, give a brief overview of the process of photosynthesis. Include where each phase takes place within a plant cell.

Answers

Photosynthesis is when light energy is converted to chemical energy. The plants takes in carbon dioxide and water. This transforms it into oxygen and glucose. The chlorophyll absorbs energy from the light and converts to chemical with water.

a vial with water,bromothymol blue,carbon dioxide , and a plant are left for 24 hours in the light. the color of the solution turns from yellow to blue . this color change is due to the plant

Answers

The dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Why the colour of the solution change?

The color of the solution turns from yellow to blue color due to the release bromothymol blue because plant can't absorb bromothymol blue so it dissolved in the solution which leads to the change of colour of the solution from  yellow to blue.

So we can conclude that the dissolution of bromothymol blue into the solution can change the colour of the solution from yellow to blue.

Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare? A. The wavelength of the UV light wave will be half that of the visible light wave. B. The wavelength of the UV light wave will be twice that of the visible light wave. C. The wavelength of the UV light wave will be four times that of the visible light wave. D. The wavelength of the UV light wave will be the same as that of the visible light wave.

Answers

If the frequency of one UV light wave is twice that of a visible light wave, then the wavelength of the UV light wave will be half that of the visible light wave (Option A)

UV is a type of electromagnetic radiation that shows a range of wavelengths from 10 nanometers (nm) to 400 nm, whereas visible light shows a range of wavelengths from 400 to 700 nm (0.4 to 0.7 µm).

UV light exhibits a higher frequency and shorter wavelength than visible light.

The frequency is a unit measured in Hertz (Hz) which indicates the number of cycles (i.e., the waves) that pass a point in space during one sec.

The longest wavelength of visible light is the red color (700nm), whereas and the shortest visible wavelength is blue (400nm).

The frequency of the visible light ranges from 7.5×10¹⁴ Hz (blue color) to 4.3×10¹⁴ Hz (red color); whereas the frequency of UV light ranges from 800 terahertz (THz) to 30,000 THz.

Answers

Answer:

Remove and lower.

Explanation:

Cells of the excretory tubule remove water by osmosis, from which we can conclude that the solute concentration in these cells must be lower than in the filtrate. The excretory tubule remove excess amount of water from the cell through semi permeable membrane of the cell while on the other hand, the solute concentration in the cell is lower as compared to filtrate so that's why it can't diffuse from the cell by the process of osmosis.

Answers

Answer:

D. Human and Chimpanzee are more related than any other pair

Explanation:

The image in this question shows a tabularized information on the amino acid sequence of hemoglobin protein in different species. This amino acid sequence can be used to deduce whether two or more species are closely related or not. The amino acid sequence of the hemoglobin of the different organisms are as follows:

- Human: Lys-Glu-His-Iso

- Horse: Arg-Lys-His-Lys

- Gorilla: Lys-Glu–His-Lys

- Chimpanzee: Lys-Glu-His-Iso

- Zebra: Arg-Lys-His-Arg

Based on the above sequences, it can be observed that the amino acid sequence of humans and chimpanzee are the same with little to no differences while other species that have similar sequences differ in one or two amino acids. This means that Human and Chimpanzee are more related than any other pair.

Explanation:

Ecology is the study of how living organisms interact with each other as well as their environment.

Habitat is a natural environment where an organism or community of organisms live.

A population is a group of organisms of the same species living in a given area while a community consists of populations with different species living in a given area and interacting with each other.

An ecosystem consists of different living organisms (all the populations) in an area as well as the non-living environment.

The biosphere encompasses all of the ecosystem of the Earth's soil, water, and air where living organisms are found.

What conclusion can you make regarding how humans affect biodiversity? Is evidence from the graph to support your answer

Answers

Answer:

Decrease population of staghorn coral and spotlight parrot fish.

Explanation:

Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to  decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.
