Answer:

A point has no dimension and a line has one dimension.

Explanation:

The digestive system takes nutrients from food and absorbs them. The circulatory system drives those nutrients to the rest of the body's cells. From the left to the right: blood vessels, heart, villi, digestive tract.

1. The digestive system is composed of different organs. Some of them mechanically break down ingested food, while others, through enzymatic action, take nutrients and let them available to be absorbed by the intestine. Villi increase the absorption area, enhancing the number of nutrients and water absorption. These are then driven to the rest of the body's cells

2. The circulatory system (composed of vessels, capillaries, veins, arteries, and the heart) takes those nutrients from the intestine walls and transports them together with the oxygen to different cells in the organisms where they are needed.

Isotonic, hypertonic, and hypotonic refers to the concentration of solutes present in a solution in comparison to another solution.

In this case, they refer to a solution that surrounds animal cells.

When a solution is isotonic, it means that has the same concentration as the other, in this case, the cytosol of the cell, so there is no water flow across the cell membrane.

When the solution is hypotonic, water diffuses to the interior of the cell, which has a greater concentration of solutes, and in an animal cell this can cause the rupture of the cell, in opposition to what would happen in a plant cell, where the cell wall prevents this from happening.

And in the case of a hypertonic solution, as the concentration of solutes is greater outside the cell, the water leaves the cell.

This means that, from the options, a hypotonic solution can be more harmful to an animal cell (option C).

Phenotype is defined as  observable characteristics or characteristics of an organism that are the result of the interaction of genes and environmental factors. These characteristics include physical appearance and  other characteristics that we perceive.

The phenotype of an organism includes its physiological, biochemical and behavioural characteristics. Unlike genotype, which is inherited from  parents,  phenotype is influenced by lifestyle and environmental factors. Environmental factors include temperature, nutrition, humidity and the mental health of the body.

Question:

Tropical rainforests are very humid and get lots of rain. This leads to lush plant growth, including tall trees and large, colorful flowers. Primates, such as the orangutan pictured above, often live in tropical rainforests. Which of the following describes a characteristic that allows orangutans to live in the rainforest?

1- Orangutans have orange fur that blends in with the treetops



2-Orangutans have long limbs that allow them to climb trees easily



3-Orangutans have thick hair that helps to keep them warm.



4-Orangutans have small ears that do not get cold very easily.

Explanation:

The main physical characteristics of the orangutan are the large head, long and flexible arms, prominent mouth, and abundant fur with a very bright red-orange hue. Standing up, they can measure two meters and the males weigh up to 120 kg. The orangutan's arms are appropriate for its lifestyle because it spends most of its time (about 90 percent) in the trees of its home, the tropical rain forest. They even sleep in the heights, in nests made with leafy branches. In fact, Sumatran orangutans have long, strong arms, 1 or 1/2 times the length of their legs that enable them to move easily in the trees.

Sex determination.

Separate sex determining i.e. male and female.

In sex determination, male and female differs only through sex chromosomes i.e. x and y chromosome. x chromosome for male and y chromosome for female. Autosomes(non - reproductive cells) does not involve in sex determination. Only the sex chromosomes involve in sex determination. Overall, only this chromosomes ( x and y) decides whether the resultant baby is male or female. If it is x chromosome, then it is a female and if y chromosome, then it is a male.

The viruses have 3 main parts, the genetic material, the capsid, and some proteins.

in the image, we can see that inside we have the genetic material, and it is protected by the capsid. So the number 7 would be the genetic material.

and the number 9 would be glycoproteins that help the virus to recognize the target cell and allow the viruses to get in the cell, besides keeping the integrity of the genetic material.

Genetic, species, and ecosystem diversity are the three levels of biodiversity that are most frequently discussed. The various genes found in each unique species of plants, animals, fungi, and microbes make up genetic variety. It can happen both within and between species.

It is essential to life on Earth that all living things are diverse, including ecosystems, plants, animals, their habitats, and their DNA. In addition to supplying oxygen, food, clean water, fertile soil, medicines, shelter, safety from storms and floods, a stable climate, and recreation, biodiversity is essential to human survival.
