Answer:
How is the shape and size of red blood cells related to their function?
This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.

Glucose molecules bond together in a process known as dehydration synthesis. What happens in this process?
Group of answer choices
The reaction uses water molecules to break the bonds in each glucose.
4 Water molecules are used for every
1 water molecule is lost (OH + H) for every bond formed
4 water molecules are lost from each bond broken
Answer:
In the dehydration synthesis reaction above, two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose. One of the glucose molecules loses an H, the other loses an OH group, and a water molecule is released as a new covalent bond forms between the two glucose molecules.
Explanation:
i hope this helps anyway
Glucose molecules bond together in a process known as dehydration synthesis. The process includes 1 water molecule is lost (OH + H) for every bond formed. The correct option is C.
What is dehydration?Dehydration is a process of chemical reaction in which water is lost. A water molecule is released during the process of making larger molecules out of smaller monomers, which is known as dehydration synthesis.
In the synthesis process, the glucose monomers are bonded together and with each bond, the water molecule is lost in the process. From monomers of glucose, polymers are formed, like starch, and cellulose.
Polymers are formed through the process of dehydration synthesis. These polymers are DNA, proteins, and carbohydrate.
Thus, the correct option is C. 1 water molecule is lost (OH + H) for every bond formed.

If you reduced three sponge species down to individual cells using a very fine cloth and mixed them together, what would you predict would be the outcome after a period of time? Make sure to identify why, and what proteins are likely responsible.
After a few hours, the cells of each sponge would re-aggregate and form three new sponges.
We can reach this answer because:
The sponge is a multicellular organism with little cell differentiation.The surface of sponge cells has a group of glycoproteins, which allow communication between all the cells in a sponge.These proteins are transmembrane receptors, which emit signals responsible for the cell adhesion process.The cell adhesion process allows the cells in a sponge to regroup if they are separated.In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

Recently there has been a decline in the abundance of life on coral reefs. Scientists are unsure why, but one of the explanations for it is that global temperatures are increasing, making water temperatures rise. These small changes are killing off some of the smallest animals on the reef, which then affects the entire food chain. Which of the following would NOT help protect the diversity of the coral reef?
a: creating coral reefs in cooler waters ?
b: limit fishing around reefs
c : ban places of anchors in reef
d: ban cities into discarding sewage into coral reefs
Limit fishing around reefs would not help to protect the diversity of coral reefs.
What are coral reefs?Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs.
Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.
Coral polyp colonies are bound together by calcium carbonate to build reefs.
According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.
The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.

how the function of the basal cells depends on the relationship among its parts?(respiratory system )
Answer:
Basal cells are found at the bottom of the epidermis — the outermost layer of skin. Basal cells produce new skin cells. As new skin cells are produced, they push older cells toward the skin's surface, where the old cells die and are sloughed off.
Answer:
The respiratory system works directly with the circulatory system to provide oxygen to the body. The primary function of the respiratory system is to deliver oxygen to the cells of the body's tissues and remove carbon dioxide, a cell waste product.Respiratory systems work together to circulate blood and oxygen throughout the body.The respiratory system subdivides into a conducting portion and a respiratory portion. The majority of the respiratory tree, from the nasal cavity to the bronchi, is lined by pseudostratified columnar ciliated epithelium. The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.The conducting piece of the respiratory system consists of the nasal cavity, trachea, bronchi, and bronchioles. The luminal surfaces of this entire portion have a lining of ciliated pseudostratified columnar epithelium and contain goblet cells. Their role is to secrete mucus that serves as the first line of defense against incoming environmental pathogens. Cilia move the mucus-bound particulate up and away for expulsion from the body. The various types and abundance of cells are dependent on which region of the airway they are.

Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.
Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).
Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.
Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

Hello
How are u doing
Enzyme activity generally increases as temperature increases within an enzyme’s optimal range because an increase in temperature causes an increase in molecular motion. This increase in molecular motion results in the enzyme and its substrate coming into contact with each other more often. At too high a temperature, however, the enzyme will become denatured and no longer be able to function. As the video describes, that is what happens when someone has a high fever.
What do you think happens to enzyme activity as temperature decreases outside an enzyme’s optimal range? Explain your answer in terms of molecular motion.
This most reliable temperature is commonly around human frame temperature (37.5 °C) for the enzymes in human cells. Above this temperature, the enzyme shape begins to interrupt down denature given that at better temperatures intra- and intermolecular bonds are broken because of the enzyme molecules' advantage of even greater kinetic electricity.
Each enzyme has a temperature variety in which a maximal charge of response is accomplished. This maximum is referred to as the temperature most desirable of the enzyme. The most excellent temperature for maximum enzymes is set at ninety-eight. 6 tiers Fahrenheit (37 ranges Celsius). There also are enzymes that work nicely at decreased and better temperatures.
Most activity is accomplished on the enzyme's ultimate temperature. The lively website online of the enzyme modifications shape as the temperature rises above the surest temperature, resulting in a decline in interest. Above and under the highest quality temperature, activity decreases.
Most enzyme functions are done at 37∘C in humans due to the fact the enzymes are capable of holding their structure at that temperature, allowing it to break down complex molecules efficiently.
