<h2>Question no 1:</h2><h2>Answer:</h2>

The correct answer is option A which is Sarah is correct because genetic diversity occurs over a long period of time.

<h3>Explanation:</h3>

Genetic diversity is a large number of allelic combinations for a trait in specie in a population.
Genetic diversity is caused due to mutations or random breeding in a specie.
It is good for the adaptation of specie in an environment, due to diverse in genotypes and phenotype of a trait.

<h2>Question number 2:</h2><h2>Answer:</h2>

The correct answer is option B which is the species will adapt to the changes.

<h3>Explanation:</h3>

Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
If the environment changes, the first thing a specie do is an adaptation to that change in the environment.

<h2>Question 3.</h2><h2>Answer:</h2>

The correct answer is option D which is, "The spines of a cactus protect it from animals".

<h3>Explanation:</h3>

Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
So the plant of cactus was in danger due to animals. So the start growing spines in response to animals.
Hence the correct answer is option D.

<h2>Question 4.</h2><h2>Answer:</h2>

The correct answer is option B which is, "Marie's plant will lean toward the sun so that it can get the most sunlight".

<h3>Explanation:</h3>

The plant will lean towards the sun light by the mechanism of phototropism.
Phototropism is the mechanism of growth of the plant in a specific direction in the response of light.
There are two types of phototropism.
One is a positive phototropism in which plant grows towards the light.
The other is negative phototropism in which plant grows away from the light.
In this question,the plant will do positive tropism.

<h2>Question no. 5</h2><h2>Answer:</h2>

The correct answer is option B which is, "The dodo bird could not adapt quickly to the challenges of the environment".

<h3>Explanation:</h3>

Adaptation to an environment means changing your body in such a way to reduce the harmful affects of changing the environment on the body.
For example, the long and thick fur of sheeps in a snowy area will protect them from cold.
So the dodo could not adopt to the environment. For the positive adaption of survival, they should be afraid of sailors but the would not afraid of a sailor.
Due to which they went extinct.

Omg pls help i dunno what the frick frack this is

snow_lady [41]

Answer:

1. Mass of KCl produced = 774.8 g of KCl

2. Mass of KNO₃ produced = 13.837g

3. Moles of NaOH made = 0.846 moles

4. Moles of LiCl produced = 0.846 moles

5. Moles of CO₂ produced = 207.6 moles

Explanation:

1. From the equation of reaction, 1 mole of ZnCl₂ produces, 2 moles of KCl.

5.02 moles of ZnCl₂ will produce, 2 × 5.02 moles of KCl = 10.4 moles of KCl

Molar mass of KCl = (39 + 35.5) g/mol = 74.5 g/mol

10.4 moles of KCl = 10.4 × 74.5 g

Mass of KCl produced = 774.8 g of KCl

2. Mole ratio of KNO₃ and KOH = 1:1

O.137 moles of KOH will produce 0.137 moles of KNO₃

Molar mass of KNO₃ = 101 g/mol

Mass of KNO₃ produced = 0.137 × 101 g = 13.837g

3. Molar mas of Ca(OH)₂ = 74.0 g

Moles of Ca(OH)₂ in 31.3 g = 31.3/74.0 = 0.423 moles of Ca(OH)₂

Mole ratio of NaOH and Ca(OH)₂ in the reaction = 2 : 1

Moles of NaOH made = 2 × 0.423 = 0.846 moles

4. Molar mass of MgCl₂ = 95.0 g

Moles of MgCl₂ in 40.2 g = 40.2/95.0 = 0.423 moles

From the reaction equation, mole ratio of MgCl₂ and LiCl = 1:2

Moles of LiCl produced = 2 × 0.423 = 0.846 moles

5. From the equation of reaction, 1 mole of C₆H₁₀O₅ produces 6 moles of cO₂

34.6 moles of C₆H₁₀O₅ will produce 34.6 × 6 moles of CO₂

Moles of CO₂ produced = 207.6 moles

Where are the noble gases on the periodic table and what characteristics do they have?

OlgaM077 [116]

<span>the noble gases are those who occupy the eighth group of the periodic table and are so called because having the complete valence shell do not need to form bonds with other atoms and are thus in atomic form ...
</span>
The noble gases (also called rare gases) are of the inert gases that constitute the eighteenth [1] group of the periodic table of the elements, ie, the right-most column. They consist of atoms with electron shells full. It includes the following elements: helium neon argon krypton xenon radon Ununoctium <span>Sometimes they (particularly helium) are located together with other gases (mostly nitrogen and methane) into endogenous sources; helium of endogenous origin comes from the decomposition of radioactive elements present in the subsurface that emit α particles (ie ions He2 +): These oxidized species present in the soil and become elio.I atoms of the noble gases are all monatomic gas, not easily liquefiable, present the atmosphere in different percentages; the most common is argon which is approximately the 0.932%.</span>
