Because they are not formed of cells, viruses cannot maintain a steady state, develop, or generate their own energy. Viruses are more like robots than actual living things, even though they do multiply and adapt to their surroundings.

The ability to replicate and mutate are two aspects of life that viruses possess, but only in live host cells.

Viruses and bacteria differ greatly from one another. While viruses may grow in both living and nonliving environments, bacteria are found in nature. While viruses might perish without a host, bacteria can live without one. Viruses reproduce by lytic fission, whereas bacteria reproduce through binary fission.

Although they are minuscule as well, viruses are distinct from other microbes.

Viruses are intracellular creatures (they infect the host cell), whereas bacteria are intercellular organisms (they exist in between cells).

When the simple squamous lines the cardiovascular and lymphatic system, it is called endothelium.

While epithelial cells line outer surfaces, endothelial cells line inner surfaces. Simple squamous endothelial are flat cells that line the inner surfaces of the heart, blood vessels and lymphatic system. They are continuous and form a barrier between the circulating blood or lymph and the walls of the vessels.

There are two types of endothelial cells - Vascular endothelial cells and Lymphatic endothelial cells. The vascular endothelial cells are constantly in contact with blood and line the inner surfaces of blood vessels, from the heart all the way to the tiniest capillary. Lymphatic endothelial cells can be found in the lymphatic system.

In the glomerulus of the kidney, endothelial cells are responsible for fluid filtration. They also help in blood clotting and formation of new blood vessels.

The two causes of competition between two species are the habitat has only a limited quantity of resource both species need and the species do not have a way to partition a resource they both need. Thus, the correct options are c and d.

Competition is a type of interaction between species which occurs when the two species require same resource that is available in limited amount. So, the availability of the resource to one species is negatively influenced by the presence of the other species which leads to competition and exclusion of one species from the environment.

Competition between two species occurs when both the species are using the same resources in an area. Competition is of two types interspecific and intraspecific competition. In competition, the species do not have a way to partition the resource they both need.

The air-sea differential in atmospheric composition and the interchange ratio, which regulates how rapidly a gas molecule may traverse the ocean-atmosphere border, are the main factors controlling the physio-chemical process of air-sea gas exchange.

Carbon dioxide is released during cellular respiration/gas exchange as a waste product. Cells that are capable of photosynthesis can utilise this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of respiration/gas exchange. From both the environment into the seas and from the seas into the atmosphere, gases are transported. The difference in gas concentration between both the atmosphere and the water, as well as the wind speed, are the two most significant variables that affect gas exchange.

The pearl buying and selling market a “setup” is all four businesses are owned by the same man, giving the impression of competition even though there is none.

John Steinbeck, an American author, wrote a novella titled The Pearl. The tale, which was first released in 1947, centers on a pearl diver named Kino and examines man's motivations as well as greed, disobedience of social conventions, and wickedness. During a visit to the formerly pearl-rich region in 1940, Steinbeck heard a Mexican folk tale from La Paz, Baja California Sur, Mexico, which served as his inspiration.

La Perla, a 1947 Mexican movie, and Ondu Muttina Kathe, a legendary Kannada film, were both adaptations of the book (1987). One of Steinbeck's best-known works, the narrative has been extensively used in middle and high school courses.  Some people believe that The Pearl is a parable.

Answer:The electronegativity difference between F-Cl is 3.98 - 3.16 is 0.82. Therefore, in the F-I bond, the electronegativity difference is greatest.

Explanation:

In a diatomic molecule with two identical atoms, there is no difference in electronegativity, so the bond is nonpolar or pure covalent. When the electronegativity difference is very large, as is the case between metals and nonmetals, the bonding is characterized as ionic.Cesium fluoride has both the most electronegative atom and the least electronegative atom. Therefore, it must have the greatest difference in electronegativity between its atoms.

In this stage of mitosis chromosomes are split at the centromere and pulled to opposite ends of the cells is known as anaphase.

Metaphase leads to anaphase, during which each chromosome's sister chromatids separate and move to opposite poles of the cell. Enzymatic breakdown of cohesin — which linked the sister chromatids together during prophase — causes this separation to occur. Upon separation, every chromatid becomes an independent chromosome. Meanwhile, changes in microtubule length provide the mechanism for chromosome movement. More specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles. Then, in the second part of anaphase — sometimes called anaphase B — the astral microtubules that are anchored to the cell membrane pull the poles further apart and the inter polar microtubules slide past each other, exerting additional pull on the chromosomes.

Vasoconstriction; their extremities will turn pale or blue as blood moves to the core of the body also their Sweating; the water released from their skin will evaporate.​

Vasoconstriction slows down the body's heat loss through the skin's blood vessels, warming the body. The body attempts to regain homeostasis as part of a negative feedback loop, which includes this action (maintaining a constant internal environment).

As an illustration, vasoconstriction causes the blood vessels to constrict and blood to move at a higher pressure in an effort to actively prevent a hypoxic reaction.

Your sweat glands produce perspiration when your hypothalamus feels that you are too hot, which helps to cool you off. The hypothalamus sends messages to your muscles to twitch in order to warm you up when it detects that you are too cold. Maintaining equilibrium is what we mean by this.

Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegration per second of a radioactive material to decrease by one-half.

Now,

If the half-life of 4Cis 5700years, then that means after 5700years have happened, there will be half of the original amount, i.e. 50%of the original amount of 14Cleft.

So, after 2476years, the sample of 14Chas evolved:

2476/5700≈43.4%of a half-life.

A rule to remember is that if nis the number of half-lives elapsed, there will be 100/2n%of the original amount of substance remaining.

In a negative feedback loop, the sensor, the integrating center, and the effector are always found in different areas of the body is false.

Explanation:

Feedback is a method where one element controls another by either positive or negatively feedback. Positive feedback is a method in which an activity's results drive more of the same action to take place inside a feedback loop. It makes the first action stronger. Negative feedback, on the other hand, occurs when the outcomes of an activity prevent that action from happening again. These systems are present in a wide variety of biological systems. Sugar is converted into cells by insulin, which causes a decrease in blood sugar levels. The insulin secretion will stop resulting into low blood sugar levels. The insulin reaction is negative feedback. Thus, the feedback usually helps to keep the system stable. This might be termed as equilibrium  homeostasis in biology.

Here are the explanation on how each of these passes from the extracellular fluid into cells:

1) Diffusion allows oxygen to move from the extracellular fluid into the cell. The concentration is quite high outside the cell and very low inside. As a result, substances reach cells through different concentration points.

2) The plasma membrane's ion channels are used to transfer calcium.

3) After entering our blood from the digestive system, ethanol enters cells with the assistance of proteins.

4) Facilitated diffusion through the plasma membrane allows glucose to enter the cell. With the aid of unique proteins found in the cell membrane, a material enters the cell via this form of diffusion.

5) Growth factor is affixed to receptors found on the surface of the cells they are trying to penetrate.
