In this course, you will learn about hormones and their effects on cells. Certain hormones bind to receptors at the plasma membrane to "deliver" their message to the cell. What function of the plasma membrane is this?.
Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.
What is plasma membrane?It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.
Characteristics of plasma membraneEnables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.
It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.
Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.

How would you recognise red blood cells when looking at a colour photograph of blood taken with a light microscope?
Answer:
Erythrocytes, or red blood cells, are by far the predominant cell type in the blood smear. They appear as biconcave discs of uniform shape and size (7.2 microns) that lack organelles and granules. Red blood cells have a characteristic pink appearance due to their high content of haemoglobin.

Describe how uncontrolled cell division is dangerous in organisms?
Answer:
Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

West Indian manatees are large aquatic mammals that live in rivers and near shore estuaries, especially in Florida. They have two flexible front flippers with three or four toenails, similar to elephant toenails. Though they lack hind limbs, manatees have vestigial pelvic bones, as shown in the diagram. Manatee and elephant skeletons are shown side-by-side. The manatee, an aquatic animal, has a skeleton that has two large front limbs and two very tiny hind limb bones that do not form actual limbs. The elephant has four large limbs. Which of the following answer choices best describes how evidence of the manatee toenails and pelvic bones supports the scientific theory of evolution of these animals? The fact that manatees and elephants have toenails and pelvic bones suggests that their limbs evolved for similar use in similar environments. The fact that manatees lack hind legs, unlike elephants, suggests that manatees and elephants evolved toenails in parallel without any common ancestry. The existence of pelvic bones and toenails in manatees and elephants suggests that manatees and elephants evolved from the same land animal. The existence of pelvic bones and toenails in manatees and elephants suggests that these animals are evolving into similar animals.
The existence of pelvic bones and toenails in manatees and elephants
suggests that manatees and elephants evolved from the same land animal
best supports evolution theory.

Please Correct the following sentence:
"Oxygen and glucose (stored energy with carbon) are the products of photosynthesis. The carbon is created by the plants to make glucose and transferred to animals that eat the plants which illustrates the conservation of mass of carbon"
Thank you ^w^
Answer:
Carbon is not created by plants
Explanation:
Plants take in carbon from the atmosphere around them to use in photosynthesis. It is true that carbon dioxide is a reactant of photosynthesis, but a plant cannot create carbon. However, (because of the law of conservation) the carbon is still transferred to the animals that eat the plant. The carbon dioxide is broken down and separated into glucose and oxygen. This glucose and oxygen are the products of the reaction.

The relationship is that as a cell's surface area-to-volume ratio increases, the efficiency of waste transport from inside the cell to the outside environment improves.
The surface area-to-volume ratio is a critical factor in determining a cell's efficiency in various processes, including the transport of wastes. This ratio represents the relationship between the cell's outer surface area (which determines the rate of exchange with the environment) and its internal volume (which determines the amount of material that needs to be transported).
In smaller cells or cells with a higher surface area-to-volume ratio, a larger proportion of the cell's interior is in close proximity to the cell membrane. This proximity allows for more efficient exchange of gases, nutrients, and waste products between the cell's interior and the external environment. Waste products that accumulate in the cell can diffuse more readily to the cell membrane for elimination.
In contrast, as cells grow larger and their volume increases, their surface area-to-volume ratio decreases. This can lead to reduced efficiency in transporting wastes, as the larger internal volume requires more time for waste products to diffuse to the cell membrane. This inefficiency can potentially hinder cellular functions and contribute to cellular stress.
In summary, a higher surface area-to-volume ratio allows for more effective waste transport due to the increased exchange area at the cell membrane. This concept highlights the importance of cell size and shape in maintaining efficient cellular processes, including waste elimination, as cells strive to balance their internal needs with the demands of their external environment.
