<u>Answer:</u> The correct answer is Option C.

<u>Explanation:</u>

Photosynthesis is defined as the process in which plants take up carbon dioxide and water to produce their food in the form of glucose with the help of chlorophyll and in the presence of sunlight. It takes place into two parts: Light reactions and Dark reactions.

Light reactions are light dependent reactions and it produces energy molecules of ATP and NADPH.

Dark reactions are light independent reactions which does not require light but uses ATP and NADPH to produce sugar molecules like glucose, starch, sucrose etc..

Hence, the correct answer is Option C.

Write the appropriate symbol for each of the following isotopes: (a) Z 74, A 186; (b) Z 80, A 201; (c) Z 34, A 76; (d) Z 94, A 2
beks73 [17]

Answer:  a)  _{74}^{186}\textrm{W}

b) _{80}^{201}\textrm{Hg}

c)  _{34}^{76}\textrm{Se}

d) _{94}^{239}\textrm{Pu}

Explanation:

General representation of an element is given as:_Z^A\textrm{X}

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

In an atom, when neutrons or protons are lost or gains, it directly affects the mass number of an atom.

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

It is characteristic of a particular element.

Atomic number = Number of electrons = Number of proton

a) Z 74, A 186: _{74}^{186}\textrm{W}

b) Z 80, A 201: _{80}^{201}\textrm{Hg}

c) Z 34, A 76: _{34}^{76}\textrm{Se}

d) Z 94, A 239.: _{94}^{239}\textrm{Pu}

How does the reactivity of nonmetals change as you move from left to right across the periodic table?
Rudiy27

Answer:

Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.

Explanation:

I hope this helps :)

Which is the dependent variable in an experiment? 1.what I observe. 2. what I keep the same 3.What I change in the experiment. H
shtirl [24]

Answer:

1.what I observe.

Explanation:

The dependent variable in an experiment is what is being observed in the experimental procedure.

This variable is the one that is closely tied to the effects originating from changing the independent variables.

  • Independent variables are the ones that cause the observation being studied.
  • The effects produced and then studied are the dependent variables.
