The property of water that is demonstrated when you see beads of water on a waxed car hood is adhesion.

What are the properties of water?

The properties of water are as follows:

It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.

The molecules of water possess a specific property which is known as adhesion. This property of water makes its molecule associated or bound to other water molecules in order to construct a bead of water.

This property of water is also seen when domestic utensils are attached to one another with extremely high intensity.

If perfect growing conditions allowed a population of producers to grow and increase in density, which of the following changes in the food web would be expected initially?

A. New populations of herbivores would enter the food web
B. The population size o fab herbivores in the food web would decrease
C. Members of predator populations would leave the food web
D. The population size of predators in the food web would decrease

Answers

Answer:

A.

Explanation:

The population of herbivores wouldn't decrease because their food source is being increased. Predators wouldn't leave because more herbivores come to eat the increased number of producers, thus more than likely increasing the number of predators.

Initially, it would be expected that the food web would evolve when new populations of herbivores entered it. So, the correct option is A.

What is Food web?

All the food networks in a specific ecosystem make up a food web. Each organism inside an ecosystem is a link in a number of food chains. Energy and nutrients can go along different food chains as their move through the environment.

A food web is created by the linkages between various, interdependent food chains. It involves intricate relationships between producers and consumers. Here, a variety of lower trophic level species are consumed by higher trophic level organisms.

At first, it would be anticipated that as additional population of herbivores entered the food web, it would change.

Therefore,  the correct option is A.

Answers

Answer:

Species that are sympatric species can occur in the same location and are phenotypically different.

Explanation:

Speciation is the evolutionary process by which a population of a species acquires differentiating characteristics that lead it to distinguish itself from the species it formed. Sympatric speciation is a type of speciation that consists of the genetic separation of different populations of the same species that live in the same environment (same geographical location), so that species originate by divergence between individuals, that is, they diversify due to to the appearance of isolation mechanisms these can be genetic, ethological or sexual.

Pls pls pls help How do viruses spread?

Answers

Viruses spread from person to person mainly through the tiny droplets that are produced when a person carrying the virus coughs or sneezes. Those droplets, whether we can see them or not, may fly and land on a surface. Some may land directly on the mouth, nose or eye of another person while others may land on a hard surface like a phone, doorknob or countertop. However, if a virus particle has been brought into your body, it doesn’t guarantee you will get sick. The lungs have cells and mucus lining them that help to trap or get rid of bacteria, particles and viruses. If the virus manages to get past the lungs’ security systems, the protein in the virus must find the perfect cell to bind to, one with the right protein to receive it. The location of the needed receptor plays a major role in whether the host will get sick. Hope that helps
