how does oxygen have a direct effect on sea urchins
Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.

what would happen to you metabolically if all your mitochondria were destroyed
Answer:
You would die
Explanation:
if you lost your mitochondria you would die
The loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing Fatty acid metabolism and calcium homeostasis.
Mitochondria are known as the "powerhouses" of the cell because they are responsible for producing most of the cell's adenosine triphosphate (ATP).
The following processes would be affected:
1. ATP production: Without functional mitochondria, ATP production would be significantly reduced, leading to a severe energy deficit within the cell.
2. Oxidative phosphorylation: Mitochondria are crucial for oxidative phosphorylation, a process that occurs in the inner mitochondrial membrane and generates a large amount of ATP. Without intact mitochondria, oxidative phosphorylation would be disrupted, impairing ATP synthesis.
3. Metabolism of fatty acids: Mitochondria are involved in the breakdown of fatty acids through a process called beta-oxidation. If mitochondria were destroyed, the ability to efficiently metabolize fatty acids would be compromised.
4. Reactive oxygen species (ROS) regulation: If mitochondria were destroyed, the regulation of ROS levels would be impaired, potentially leading to oxidative damage and disruption of cellular processes.
5. Calcium homeostasis: Mitochondria are involved in maintaining calcium homeostasis within cells. Loss of functional mitochondria would disrupt calcium regulation, which could affect various cellular functions, including muscle contraction, enzyme activity, and cell signaling.
Therefore, the loss of functional mitochondria would result in a severe energy crisis within the cell, affecting ATP production and impairing various metabolic processes.

Skeletal muscle exhibits alternating light and dark bands called a sarcomere
Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.
What is skeletal muscle?Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).
Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.
When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.
Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.

Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

Facilitated diffusion uses -----------------to help aid some substances across the cell membrane.
Facilitated diffusion uses transport proteins to help aid some substances across the cell membrane.
Facilitated diffusion is a passive transport process that enables the movement of specific molecules across the cell membrane with the assistance of transport proteins. While simple diffusion allows small, non-polar molecules to pass directly through the lipid bilayer of the cell membrane, facilitated diffusion comes into play when larger molecules or molecules with charges need to cross.
Transport proteins act as gateways or channels in the cell membrane. They are selective and only allow specific molecules to pass through. There are two main types of transport proteins involved in facilitated diffusion: channel proteins and carrier proteins.
Channel Proteins: These proteins form pores or channels in the cell membrane, allowing certain molecules, such as ions or water, to pass through. Channel proteins are highly specific and only allow certain substances to cross.
Carrier Proteins: These proteins undergo a change in shape to "carry" molecules across the membrane. When a specific molecule binds to the carrier protein, it triggers a change in the protein's shape that transports the molecule across the membrane. Once the molecule is released on the other side, the carrier protein returns to its original shape.
Facilitated diffusion is a crucial process for maintaining the balance of ions and molecules inside and outside the cell. It's important for the transport of nutrients, ions, and other essential molecules that may be too large or polar to diffuse directly through the lipid bilayer. The involvement of transport proteins ensures that only specific substances are transported, preventing unwanted molecules from entering or leaving the cell. Overall, facilitated diffusion is a highly regulated process that contributes to the homeostasis of the cell and the overall functioning of the organism.

How are male and female reproductive organs similar?
Answer: They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.
What is the source from where organisms get glucose?
This is apart of cellular respiration
Answer:
The source of glucose molecules in plants is the product formed by the process of photosynthesis which is ultimately stored in the parts of plants. In animals, glucose is formed by the oxidation of carbohydrates which are obtained from food.
Explanation:
In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration.
