True or False: Active Transport requires
ATP to transport molecules with the
concentration gradient.
Answer:
the statement is true
Explanation:
The main difference between active and passive transport is that in active transport, solutes are moved from an area of low to high concentration (against the concentration gradient) and requires the energy released from ATP hydrolysis
Answer:
Explanation:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

The cytoplasm in a single cell organism and the circulatory system in a human both do
what?
According to the research, the cytoplasm in a single cell organism and the circulatory system in a human both allow substances to move in the body.
What is the cytoplasm and the circulatory system function?The cytoplasm is the part of the cell where numerous chemical and organic substances are dissolved and suspended, contributing to their movement, necessary for cell physiology.
In this sense, the circulatory system is the functional unit for the supply and distribution of blood to the different parts of the body.
Therefore, we can conclude that the cytoplasm and the circulatory system allow the mobility of substances that are essential for a cell and organism.

Sammi decides to design a model to show how the digestive and circulatory systems interact. She lines a large plastic tube with a corrugated cardboard tube. Then, she connects smaller plastic tubes to the large plastic tube. These small tubes connect to a pump. She drills small holes in the large tube so that all of the plastic tubes connect. She plans to run a green fluid representing food through the cardboard tube.
Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
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.
From the left to the right: blood vessels, heart, villi, digestive tract.

Guillaume Néry: The exhilarating peace of freediving
The unit discusses and defines hydrostatic pressure. Explain what hydrostatic pressure is and how this term relates to Néry’s talk.
Explain what the term “blood shift” means and how it works.
Describe what happens when Néry falls below 80 meters in depth. How must Néry react in order to survive, and even enjoy, falling to such depths?
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.
Nery explains how he can unwind and let the water draw him deeper. This was the most fascinating to me.
How to illustrate the information?The force that fluids apply against the capillary wall is known as hydrostatic pressure.
Nery explains how he can unwind and let the water to draw him deeper. I'm drawn to this because I enjoy being in the water and enjoying the serenity of the silence. The fact that our bodies may be trained to defend ourselves and mount a defense against stressors also intrigues me.

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.
Answer: we can conclude that the correct answer is:
Orangutans have long limbs that allow them to climb trees easily7.Type the correct part of the virus, indicated by the number 7,________9. Type the correct part of the virus, indicated by the number 9____________
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.

Animal cells are most likely to experience damage froma. an aqueous solution.b. an isotonic solution.c. a hypotonic solution.d. a hypertonic solution.e. None of these.
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).
Summarize what happens during the Calvin cycle.
The Calvin cycle is a series of chemmical reactions that are part of the dark reactions of a photosynthesis, turning carbon dioxide into sugar. It is composed of three main phases:
1 - Carbon fixation, in which carbon dioxide (CO2) is turned from the inorganic molecule that it is to an organic molecule.
2 - Reduction, in which energy from ATP and from NADPH is used to convert the organic carbon molecules into a simple sugar
3 - Regeneration, in which glucose is produced and the molecule that started the cycle is regenerated so the cycle can continue, as the cycle must be completed a three times until it has produced the product molecules (six G3P's - Glyceraldehyde 3-phosphate).

According to the Centers for Disease Control and Prevention, lead exposure can impair cognitive development, especially in young children, and federal experts say no quantity of lead in drinking water is thought to be safe for their intake. Flint's lead water issue was caused by the city's decision to temporarily reduce costs by switching its water source to the Flint River without sufficient treatment, which corroded its lead pipes. After the water catastrophe in Flint, Michigan toughened lead drinking water standards in 2018, bragging that it had passed the country's most protective regulation.
