Which cellular component is considered an organelle?

Answers

Answer:

Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells. Membrane-bound organelles. Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.

Have a great day friend! :D

Answer:

Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.

Explanation:

ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.

What’s the term to describe a mutant viral protein without a genetic code that can cause disease?

Answers

Answer:

'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.

Explanation:

The term to describe a mutant viral protein without a genetic code that can cause disease is a "prion." Prions are abnormal forms of proteins that can induce misfolding of normal proteins, so option a is correct option.

The misfolded prion protein can convert normal proteins of the same type into the abnormal misfolded form of protein, leading to a chain reaction and accumulation of misfolded proteins. This can cause damage to brain tissue and result in the characteristic symptoms associated with prion diseases, which include changes in behavior, neurological dysfunction, and ultimately, severe neurological degeneration. so option a is correct option.

A failure of the cell to break down which cyclin would most directly lead to increased cell division?

Cell researchers are investigating the role of cyclins on mitosis and cell division. They notice that cyclins build up, cause the cell to progress through the cell cycle, then break down, thus ending the different stages of the cell cycle. A failure of the cell to break down which cyclin would most directly lead to increased cell division?


A) Cyclin A

B) Cyclin B

C) Cyclin D

D) Cyclin E




The answer is: M-phase cyclins form M-CDK complexes and drive the cell's entry into mitosis; G1 cyclins form G1-CDK complexes and guide the cell's progress through the G1 phase; and so on. ... Specific enzymes break down cyclins at defined times in the cell cycle. When cyclin levels decrease, the corresponding CDKs become inactive.

The inability of the cell to break down cyclin D would most directly lead to increased cell division.

What is cell division?

Cell division is the process by which cells in the body divide their content and duplication of the chromosomes to produce new daughter cells.

In the cell cycle, proteins known as cyclins are required.

Cyclin D is required at the initiation and termination stage of cell division.

Therefore, based on the cell cycle diagram, inability of the cell to break down cyclin D would most directly lead to increased cell division.

What effect does viscosity have on blood flow?

A.) Low blood viscosity leads to slower blood flow.

B.) High blood viscosity leads to slower blood flow.

C.) Low blood viscosity increases resistance and leads to fast blood flow.

D.) High blood viscosity decreases resistance and leads to fast blood flow.

Answers

Answer:

B

Explanation:

High blood viscosity leads to slower blood flow. Therefore, option B is correct.

What is viscosity?

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction between different layers of fluid as they move relative to one another. In general, fluids with high viscosity flow more slowly than fluids with low viscosity.

Viscosity can affect blood flow by altering the resistance to blood flow in blood vessels. Blood viscosity is influenced by the thickness and stickiness of blood, which is determined by the concentration of various proteins and cells in the blood.

When blood viscosity is high, the blood is thicker and flows more slowly, which can increase the resistance to blood flow in blood vessels. Therefore, option B is correct.

Wildfires release large amounts of carbon dioxide, black carbon, brown carbon, and ozone precursors into the atmosphere. These emissions affect radia]on, clouds, and climate on regional and even global scales. Wildfires Affect Air Quality.As fires burn, carbon stored in trees and other vegetation combusts, releasing carbon dioxide and other potent greenhouse gases such as methane and nitrous oxide into the atmosphere. This means that as fires increase, so do emissions.Wildfires emit carbon dioxide and other greenhouse gases that will continue to warm the planet well into the future. They damage forests that would otherwise remove CO2 from the air. And they inject soot and other aerosols into the atmosphere, with complex effects on warming and cooling.

To be sure, the leading cause of global warming remains overwhelmingly the burning of fossil fuels. That warming lengthens the fire season, drying and heating the forests. In turn, blazes like those scorching areas across the Northern Hemisphere this summer have a feedback effect—a vicious cycle when the results of warming produce yet more warming

What is consciousness ?​

Answers

Answer:

consciousness is the difference between a rock and a hard place to stay in 6

Consciousness is a complex and multifaceted phenomenon that refers to our subjective Consciousness of the world and ourselves.

Consciousness encompasses our awareness, perception, thoughts, emotions, and the sense of self.

Some theories of Consciousness:

1. Dualism: According to dualism, the mind or consciousness exists independently of the brain and can potentially survive even after the death of the body.

2. Materialism: Also known as physicalism. According to materialism, consciousness is an emergent property of the complex interactions among neurons, neural networks, and brain structures.

3. Integrated Information Theory (IIT):  According to IIT, consciousness emerges when information is both highly integrated (information is interconnected) and highly differentiated (information is diverse).

4. Global Workspace Theory (GWT): The global workspace is a dynamic neural network that allows information to be shared across different cognitive processes and enables access to conscious awareness.

5. Phenomenal consciousness vs. Access consciousness: Phenomenal consciousness refers to what it feels like to experience something, while access consciousness pertains to the ability to use that experience for various cognitive tasks.

Thus, the term "consciousness" refers to our individualized perception of the outside world and of ourselves.
