  • 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.
  • 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.

MissTica

Question: The question is not complete. Find below the complete question and the answer.

Alab group was supposed to make 14 mL of a 36% acid solution by mixing a 20% solution, a 26% solution, and a 42% solution. However, the 20% solution was mislabeled, and was actually a 10% solution, so the lab group ended up with 14 mL of a 34% acid solution, instead. If the augmented matrix that represents the system of equations is given below, what are the volumes of the solutions that should have been mixed? mL

Volume of 20% solution= ?

Volume of 26% solution = ?

Volume of 42% solution= ?   Round to the nearest whole number ml

Answer:

Volume of 20% solution= 3 mL

Volume of 26% solution = 1 mL

Volume of 42% solution= 10 mL

Explanation:

Find attached of the calculations.
