Answers

Answer:

D

Explanation:

because wind is depositing sand to build

Wind depositing sand to build up sand dunes best illustrates a natural process acting as a constructive force. Therefore, the correct option is D.

What is a constructive force?

Constructive forces are the forces that are responsible for the formation of new landforms on the surface of the earth, such as deposition, earthquake, volcanoes etc.

Wind depositing sand to build up sand dunes is the natural process depicting the constructive force  because sand dunes are formed by constructive forces that add sediment to an area, in this case, wind depositing sand.

Option A is incorrect because river erosion is a destructive force that wears away soil and rock, rather than building it up. Option B and option C are also destructive forces. Therefore, the correct option is D.

Answer:

The correct answer is - prophase I

Explanation:

Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.

Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

what is the difference between a disease and an infection​

Answers

Answer:

disease occur when the cells in your body are damaged and multiplies and infection occurs when bacteria is there.

hopefully this helps.

A disease is any condition in which the body is not working properly. Many diseases are quite trivial and clear up quickly without treatment, for example a cold. Some are severe, even life-threatening, such as many, not all, types of cancer.

Infections are one particular type of disease. An infection is a disease caused by a living organism (a germ), which is living in the body of the affected person. The germ may be a bacterium, virus, fungus or parasite.

Like all diseases, infections vary in how severe they and whether they need treatment. The common cold is a virus infection; colds are not dangerous unless a person is already sick or very weak. Tuberculosis is a bacterial infection, which can be very difficult to treat and causes many deaths every year.

Two populations of birds with somewhat different coloration live on two different islands. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring can successfully breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees. According to the biological species concept, the two populations on different islands ___.

Answers

Answer:

represent a single species

Explanation:

According to the biological species concept, a species can be defined as a group of organisms that can potentially interbreed (i.e., mate) in order to produce viable and fertile offspring. Based on this concept, the cohesion forces that maintain the integrity of the species as a single group are 1-interbreeding between its members and 2-reproductive isolation mechanisms that prevent successful mating between organisms from different species. In this case, both bird populations represent the same species because when individuals of these populations are brought together they can interbreed to produce viable and fertile offspring.

When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L

Answers

Answer:

L means same time.

Explanation:

Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.
