Answers

Answer 1
Answer: So all we know is that the student stated something ("if plants are added to an indoor environment the air quality will improve "). This is only a statement - it's not a test whether this statement is true yet.
 
So the correct answer is: it is a hypothesis.
Answer 2
Answer: Hypothesis!!!!!!!! Is correct.

Onion root tips are often used to study mitosis because they grow very rapidly, which means that many cells are dividing. The very tip of the onion root ends in a structure called the root cap. The other end of the root attaches to the onion. A scientist is interested in determining whether an onion root tip grows from the base of the root or from the tip near the root cap. She counts the number of cells that are in one of the phases of mitosis at different distances from the root cap. What is the dependent variable in her experiment

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection

Ryan hit a baseball with an acceleration of 20 m/s2. The mass of the baseball is 0.5 kg. What is the force?

Answers

Well to find the answer for force, the formula is mass X acceleration.
So, 20m/s² X 0.5kg = 10kg-m/s².
But, because we measure force in Newtons, we have to change the units (kg/m/s²) to Newtons.
1N (newton) equals to 1kg-m/s² and because we had 10, your answer is 
10N

What causes continental lithosphere to become thinner and weaken?

Answers

Continental litosphere is made of relatively light weight minerals. It has a low density. Oceanic litosphetre is composed of a heavier minerals. Tensions and heat flow in the asthenosphere( beneath the litosphere) waekens the floating solid plate causing it to break apart. Thinning of the continental litosphere is result of hydration weakening. It is a special consequence of plate tectonics. By hydration weakening the basal portions of litosphere can be transformed into convecting asthenosphere.
