Answer:
As the cell ages the volume of cytoplasm increases, enzymes that synthesize DNA move from the nucleus to the cytoplasm, and there is a gradual build up of lipofuscin. While it is unclear how this directly affects the cell, it is known that once the DNA migrates from the nucleus it is unable to synthesizes enzymes.

How does cytokinesis in plant cells differ from cytokinesis in animal cells?
animal cells form a cell plate
plant cells form a cell plate
plant cells go through the process in reverse
plant cells go through two rounds of cytokinesis while animal cells just do once
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

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.
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.

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

in the nucleus protein synthesis is copied from DNA onto mRNA thru transcription
messenger mRNA leaves nucleus & goes to cytoplasm attaching to ribosome.
tRNA (transfer RNA) decodes & translate info on the attached mRNA via translation &
gets amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed
Which of the following correctly describes one way that cellular respiration contributes to the carbon cycle?
Choose 1 answer:
Choose 1 answer:
(Choice A)
A
Cellular respiration breaks down carbon-based molecules and releases oxygen into the atmosphere.
(Choice B)
B
Cellular respiration takes carbon dioxide from the atmosphere and uses it to make carbon-based molecules that are stored as biomass.
(Choice C)
C
Cellular respiration helps move carbon from the bodies of living organisms into the atmosphere.
Answer:
Choice A
Explanation:
Recall that trees release oxygen as a byproduct of photosynthesis. And you need oxygen to breathe. Do you know why? So your cells can perform cellular respiration and make ATP.
Cellular respiration contributes to the carbon cycle as cellular respiration helps move carbon from the bodies of living organisms into the atmosphere.
How does cellular respiration contribute to the carbon cycle?
During cellular respiration, organic molecules are broken down using oxygen molecule and carbon dioxide is released into environment.
This carbon dioxide is used by plants during photosynthesis and they synthesize organic matter.
This is how respiration contributes to carbon cycle.

What is consciousness ?
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.

A) Cyclin A
B) Cyclin B
C) Cyclin D
D) Cyclin E
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.

Why do most food chains only two, three or rarely ,four consumers after the green plant producer?
Answer:
It is rare to find food chains that have more than four or five links because the loss of energy limits the length of food chains. At each trophic level, most of the energy is lost through biological processes such as respiration or finding food
Explanation:
Answer:
Because so much energy is lost to life processes.
Explanation:
As you progress through each trophic, each organism on that level loses energy gained from the previous trophic. This is due to losing energy through wasted material (e.g. bones) and to life processes, 7 of which can be remembered by MRS GREN:
M ovement
R espiration
S ensitivity
G rowth
R eproduction
E xcretion
N utrition
This means that each time, energy is wasted and lost from the food chain. More than four trophics would result in so much energy being lost from the initial trophic (producer), that it would be largely pointless!

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.Learn more about Organelles here
