Answer:

The carrying capacity would shoot downward.

Explanation:

The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).

Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).

Answer:

The cornea in the eye.

Explanation:

The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air.  The cornea is a transparent tissue, allowing for light to pass through. If it had blood vessels there, that would be an issue - for that tissue! And the cornea receives its oxygen directly from the air. When contact lenses were first used, people were instructed to take out their contacts when they go to sleep - because wearing them at night would reduce the oxygen intake to the eyes. Then they began manufacturing contact lenses that allowed for the lenses to “breathe” permitting people to wear them day and night.

Answer:

gravity

Explanation:

the sun has a gravitational pull that keeps all the planets in orbit and prevents them from just floating away.

Answer:

The reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Answer:

C. glycoproteins

Explanation:

Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.

The structure that is used to help substances to enter and exit the cell is the cell membrane. A cell membrane is the outermost boundary or outer layer of a cell that regulates the entry and exit of ions and molecules in and out of the cell.

It is the most important component of the cell that separates the cell contents from the external environment.In general, cell membranes consist of three main components: lipids, proteins, and carbohydrates. The cell membrane is selectively permeable, which means it only allows certain molecules to pass through it, and it prevents the entry of others. The cell membrane uses various mechanisms to move molecules in and out of the cell. These mechanisms can be categorized into two types:Passive transport Active transport Passive transport: It is a type of transport that requires no energy because it occurs spontaneously along a concentration gradient. It can be further divided into two categories:Simple diffusion Facilitated diffusion Simple diffusion: In this process, small non-polar molecules like oxygen and carbon dioxide diffuse across the cell membrane from an area of high concentration to an area of low concentration.

Facilitated diffusion: In this process, ions and polar molecules like glucose and amino acids move across the cell membrane from high to low concentration with the help of integral membrane proteins.Active transport: It is a type of transport that requires energy because it moves molecules against their concentration gradient. Secondary active transport: In this process, molecules move across the cell membrane against their concentration gradient with the help of a concentration gradient that was created by primary active transport.A long answer to the question "used to help substances to enter and exit the cell" is the cell membrane, which regulates the entry and exit of ions and molecules in and out of the cell.

In liver cells, epinephrine stimulates the breakdown of glycogen. as the signal-transduction pathway progresses, the signal is amplified.

Epinephrine, also known as adrenaline, is a hormone that is released by the adrenal glands in response to physical or emotional stressors. In liver cells, epinephrine stimulates the breakdown of glycogen. This process is known as glycogenolysis. When epinephrine binds to its receptor on the surface of the liver cell, it triggers a signaling cascade that amplifies the signal. This cascade involves the activation of multiple enzymes, such as adenylate cyclase and protein kinase A, which ultimately trigger the glycogenolysis process. As a result, glucose is released from the glycogen molecules and enters the bloodstream, providing the body with a boost of energy. This helps to maintain normal oxygen levels in the body, as well as an adequate supply of glucose for the brain and other organs.

Transcription has a key role in regulating prokaryotic gene expression. Epigenetics, transcription and also translation, as well as post-translation all play roles in the regulation of eukaryotic gene expression.

At the transcriptional level, prokaryotic cells control the expression of their genes. Repressive control, activator control, and inducible control are the three mechanisms used to regulate an operon's transcription. We now understand that physical interaction between regulatory proteins and particular regulatory sites on DNA controls the production of various bacterial operons. In particular, there are two degrees of control over gene expression. The first way of transcription is dones by regulating the amount of mRNA that can be produced from a particular gene. The translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

Complex lipids called phospholipids form the core of all biological membranes. Phospholipids are a type of complex lipid that consists of a hydrophilic (water-loving) head and hydrophobic (water-repelling) tails.

The hydrophilic head is composed of a phosphate group and glycerol, while the hydrophobic tails are made up of fatty acid chains. These properties make phospholipids amphipathic, meaning they have both hydrophilic and hydrophobic regions.

In a biological membrane, phospholipids arrange themselves in a bilayer formation, with the hydrophilic heads facing outward towards the surrounding aqueous environment and the hydrophobic tails pointing inward, creating a hydrophobic core. This arrangement forms a stable barrier that separates the internal components of the cell or organelle from the external environment.

The phospholipid bilayer serves as the main structural component of biological membranes, including the plasma membrane of cells and the membranes of organelles within the cell. It acts as a selectively permeable barrier, allowing certain substances to enter or leave the cell while restricting the passage of others.

In addition to phospholipids, biological membranes also contain other components such as cholesterol, proteins, and carbohydrates, which contribute to their overall structure and functionality.
