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.

Néry describes many aspects of the entire experience of free diving that he finds appealing. What aspect of the free-diving experience that Néry describes appeals to you most? Why?
The pressure exerted by or present within a liquid when it is at rest in relation to other bodies is known as hydrostatic pressure.
When a diver encounters a rise in the pressure of the surrounding water, the phrase "blood shift" is used. Due to this, the amount of blood being pumped into the chest increases.
The pressure increases significantly below 80 meters, and Néry can actually feel it in my body. He starts to truly feel like being choked.

supercoiled DNA.
b. Condensed, replicated
chromosomes attach at a
pinched region called the
centromere.
c. DNA is wrapped around histones
at regular intervals, forming

d. Interactions between parts of
histones compact the DNA.
The processes of the alterations in chromosomal organisation that take place as a cell enters mitosis.
The correct order is:
1. Chromatin is created by the regular wrapping of DNA around histones.
2. The DNA is compacted by interactions between histone component components.
3. The DNA becomes supercoiled as the chromosome coils ever-tighter.
4. Chromosomes that have been duplicated and compressed attach at a point known as the centromere.
What transpires to DNA throughout mitosis?
Therefore, during mitosis, cells don't simply randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order. Prophase, Metaphase, Anaphase, and Telophase are the four basic phases of mitosis.
In what way do chromosomes separate during mitosis?
A mitotic spindle, a specialised structure made of microtubules, is responsible for separating the chromosomes. The cell's cytoplasm divides during this phase. It starts as soon as mitosis is complete.

Which color of eyes is dominant? How do you know this?What does this mean in terms of inheritance?
The exercise tells us that 20 babies have been born in a maternity ward, and 10 of them have brown eyes, while the other 10, have blue eyes. The questions below are related to the dominant eye color, how we know it, and what it means in terms of inheritance. To this, we can answer that the dominant eye color is the brown one and that we know this due to the dominant alleles are represented with a capital letter, in this case, B, being b (for blue color) the recessive allele. In terms of inheritance, this means that if a parent with brown eyes (being BB, or Bb their genotype, but if we have that they have babies being they blue-eyed, then the genotype would be Bb), has babies with a parent that have blue eyes (being bb their genotype), the babies would have both phenotypes, as we can see in the following Punnet Square.

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.
How do the digestive and circulatory systems work together?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.
