Answer:
More than 7000 chemicals are present in tobacco smoke.
Explanation:
In these 7000 chemicals, 250 are harmful to the human body such as carbonmonoxide, ammonia and hydrogen cyanide etc. There are some chemicals that are found in tobacco smoke which causes cancer disease in human. About 69 chemicals out of 250 are present in tobacco smoke that causes cancer disease. So its consumption is dangerous for health.
Answer:
1.
3.
4.
Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. s<em>o, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.</em>
<em>Hence, the correct options are 1, 3 and 4.</em>
The greater the attractive forces between substrate and enzyme, that
enzyme is said to have a higher affinity for the substrate.
<h3>What is an Enzyme?</h3>
This is a substance which acts as a catalyst in regulating the biochemical
processes of the body.
Enzymes are substrate-specific which means they act only on some types
of compounds. For example the enzyme protease acts only on protein.
When the attractive forces between substrate and enzyme is great then
the enzyme is said to have a higher affinity for the substrate.

Color patterns can be thought of as mosaics of different-sized, form, brilliant, and colored patches. A number of natural conditions, including ambient light, watercolor, viewing distance, and the visual capabilities of guppies and three of their predators, were used to assess how noticeable guppy color patterns were.
A particular color pattern element (patch reflectance )'s spectrum, the medium's transmission spectrum, and the ambient light spectrum that strikes the patch all interact to determine the light spectrum that reaches the eye's surface (air or water).
The light at distance x from the patch that reaches the eye at any given wavelength, I, is the result: Q(& x) is the photon flux from the patch reaching the eye (patch radiance), and Q(A) is the photon flux of ambient light incident on the patch.
Predation intensity varies spatially with guppy color patterns, which are influenced by the make-up of the predator communities (Endler, 1978). As a result, calculations were made independently for the color patterns of guppies that are unique to three different predator communities.
