it takes 5 seconds for a nutrient to diffuse from the blood to a cell which is 100 micrometers from the nearest capillary.

Capillaries are small blood vessels lined of a single layer of endothelium. The exchange of gases and nutrients that take place between the blood and tissues is the function of the capillaries. Oxygen from the red blood cell and nutrients in the blood diffuses into the tissues, while carbon dioxide from the tissues diffuses out into the blood. The carbon dioxide is then transported to the lungs, where it will be exhaled.

If voltage-gated sodium channels remained inactivated, the absolute refractory period would be more extensive than usual.

Voltage-gated sodium channels- Ion channels that are triggered by change in electrical membrane potential close to the channel are known as voltage-gated ion channels. The cell membrane potential modifies the channel proteins' shape, controlling how they open and close.

Cell membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The cell membrane regulates the transport of materials entering and exiting the cell.

Homologous chromosomes specifically separates during meiosis I.

There are two divisions in meiosis, and they both proceed through the same stages as mitosis (prophase, metaphase, anaphase, telophase). Interphase, during which DNA is duplicated to create chromosomes made up of two sister chromatids, comes before meiosis. Between meiosis I and II, a second growth phase known as interkinesis may take place; however, no DNA replication happens during this phase.

1. Meiosis

Prior to the work of Carl Woese blank, scientists did not distinguish between members of the archaea and the bacteria.

Explanation:

Prokaryotes, which comprise two very different species i-e bacteria and archaea, may be found practically everywhere, including within human bodies as well as on every surface of the dwellings. Some inhabit habitats that are too harsh for other types of life, such as the warm pores on the seafloor. Prokaryotes are everywhere, yet they may be challenging to find, quantify, and categorize. Only a small portion of the prokaryotic on the planet that are predicted to exist are represented by those that we now learn about. In reality, in the environment of prokaryotes, the concept of a "species" itself becomes complex.

The difference in concentration between solutions on either side of a cell membrane is a concentration gradient.

In the field of biology, a concentration gradient can be described as a difference in the concentration of molecules inside and outside of a cell. It is due to concentration gradient that molecules move into and out of a cell through the cell membrane.

Some molecules move from an area of higher concentration gradient to an area of lower concentration along the concentration gradient. Diffusion is an example of such a process.

Functional groups containing Oxygen and Nitrogen atoms usually increase the polarity of a molecule.

Explanation:

Oxygen is one of the most important elements in the periodic table. Its atomic number 8 and atomic mass is 16. About 1772, a Swedish scientist named Carl Wilhelm Scheele made the discovery of oxygen. Some compounds like alcohol, water, carboxylic acids, ketones and many others contain oxygen which make them polar.  Among all these compounds water is the most important oxygen containing compound.

The scientific name for nitrogen is N, and it is a flavorless and colorless element. The ground beneath our feet contains nitrogen, as does the water that we drink as well as the air we inhale.  Atmosphere contains about 78% of Nitrogen.   Nitrogen containing compounds are ammonia, nitric acid and many others.

Cell damage may be caused by exogenous sources such as abnormal metabolic processes. So the correct option is A.

If enough cells are destroyed as a result of toxic damage to cells, there may be tissue or organ failure, which eventually results in organism death. Discussions of cellular toxicity and biochemical toxicity are essentially inseparable.

The majority of detectable cellular alterations and cell death are brought on by certain biochemical alterations either inside the cell or in the tissue around it. There are, however, a few circumstances in which a harmful chemical or physical substance might harm cells without actually altering any particular chemicals present in the cell or its membrane.

Physically damaging substances like heat and radiation can harm a cell by coagulating its contents (similar to cooking). There are no particular chemical reactions in this situation. A cell may be deprived of vital supplies necessary for existence due to a compromised food supply (such as oxygen and glucose).

The appearance or quality of light reflected from the surface of a mineral is known as luster.

In mineralogy, luster refers to how a mineral surface appears in terms of its capacity to reflect light. The degree of transparency, diaphaneity, and structure of a mineral all affect its luster.

A mineral's ability to reflect light is referred to as luster. The first step in identifying a mineral is to measure it. Always examine a brand-new surface for luster; you might need to remove a tiny amount of material to reveal a clean sample. Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)

Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.

Lipid-derived (soluble) hormones can enter cells by passing through the plasma membrane, binding to DNA, and controlling gene transcription. They can also alter cellular activity by triggering the creation of proteins that have an overall impact on the cell's long-term structure and function.

The only known method through which steroid hormones may reach cells is by free diffusion through the plasma membrane. Recent research, however, raises the possibility that carrier-bound steroids have cellular absorption mechanisms.

Once at the target tissue, steroid hormones are liberated from the binding protein and since they are lipophilic, they may readily diffuse through the plasma membrane to enter cells. Only free, unbound steroid is physiologically active, thus once at the target tissue. Steroid hormones exist within the cell.
