Biology

Answer:

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. so, 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.

Hence, the correct options are 1, 3 and 4.

Se efectúa un experimento en el que a la planta 1 se le suministra CO2 normal pero agua que contiene átomos de oxígeno radiactiv

algol [13]

Answer:

The Oxygen liberated in photosynthesis comes from photolysis of water.

The CHO formed from Calvin Cycle during photosynthesis comes from reduction of CO2 with H+ of photolysis of water.

Therefore,since Plant 1 contains labeled Oxygen(from water) it will give radioactive Oxygen as the byproduct of its photosynthesis. It CHO is normal.

However,Plant 2, will contain radioactive CHO,because its radioactive CO2 will be reduced by H+ from photolysis of water to form radioactive labeled carbohydrate(CHO)

How does leaf structure best represent the relationship between structure and function? It indicates the maximum height an organ

vova2212 [387]

Answer:

The correct answer is - *It relates directly to the characteristics of the plant's environment*

Explanation:

The relationship between structure and function can be represented by the leaf structure as the structure of a particular plant leaf gives an idea about the characteristics of the environment it is habituated.

In the dry area or deserted area, leaves are modified into spikes to save water in order to lower transpiration, number of waxy coating, number of chlorophyll, and other modifications that give an idea about the environment and light intensity, and other characteristics.

What is true of a regulatory approach to environmental problems?

tankabanditka [31]

<h2>Regulate of Environmental</h2>

Explanation:

The motivator based administrative methodology progresses in the direction of forestalling ecological issues by giving promptings to urge contaminating substances to diminish contamination.
An advantage of the motivator based methodology is that it energizes the production of imaginative and financially savvy techniques for contamination control.
Administrative methodologies require government offices to limit or direct the exercises of controlled gatherings utilizing terms and conditions inside statutory and administrative instruments, working grants, licenses, endorsements or codes of training.
Command and control causes administrators to benefit as much as possible from whatever hardware they have - individuals, data, material, and, regularly generally significant of all, time.
Particles have assisted with securing nature, they have three weaknesses.

They give no motivating force to going past the cutoff points they set.
They offer restricted adaptability on where and how to lessen contamination.
They regularly have politically-spurred escape clauses.
