Answer:

False

Explanation:

Organisms themselves cannot choose to have a mutation. However, it can be artificially done in labs.

Organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

mutation has many consequences, such as the Mutations can cause developmental disorders such as birth defects, mutations can increase an individual's risk of developing genetic disorders, and they also reduce the genetic diversity of a population. Mutation leads to the loss of function in an essential gene, resulting in a decrease in the organism's fitness in the ecosystem.

Hence, organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

Answer:

If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.

Explanation:

Hope it helped!

Answer:

If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Explanation:

Answer:

1. Metaphase

2. Prophase

3. Telophase

4, 5, 6, 8. Interphase

7. Anaphase

Explanation:

Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.

Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.

Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.

Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.

Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.

In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.

The cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).

In conclusion, the cellular phases include Interphase (Figs. 4, 5, 6, 8), Prophase (Fig. 2), Metaphase (Fig. 1), Anaphase (Fig. 7) and Telophase (Fig. 3).

Answer:   When you kick a ball, forces start to act on it immediately. These include resistance or friction from the air and gravity. Gravity pulls the ball down to the ground and the air resistance slows it down. The second law states that the greater the mass of an object, the more force it will take to accelerate the object.

Answer:

D

Explanation:

Let's assume there's two cuboidal cells, cell A and B

Cell A has a side of x

Let's find the surface area of cell A

SA = 6(L²)

SA = 6(x²)

SA = 6x²

Let's find the volume of cell A

V = L³

V = (x)³

V = x³

Cell B has a side of 2x

Now let's find the surface area of cell B

SA = 6(L²)

SA = 6(2x)²

SA = 24x²

Let's find the volume of cell B

V = (L)³

V = (2x)³

V = 8x³

As you can see, just by doubling the side length, the ratio between Surface Area and Volume went from 6/x to 3/x (the x² in the numerator and the x³ in the denominator cancel out forming 1/x)

The ratio decreased, therefore, D is the statement that makes sense

Explanation:

The greenhouse effect is caused by a buildup of carbon dioxide in the atmosphere, the trapping of the sun's heat and pollution from burning fossil fuels.

The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space.

The greenhouse effect is the way in which heat is trapped close to Earth's surface by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around Earth, keeping the planet toastier than it would be without them.

One example of the greenhouse effect that most of us experience in everyday life is the warming of a car's interior when the vehicle is left out in the sun.

24 hours and 37 minutes

Explanation:

At Mars' orbital speed of 24 km per second, it takes the planet 24 hours and 37 minutes to complete one rotation. That is just a little more than a day on Earth.

Answer:

The Earth zips around the Sun at about 67,000 miles per hour, making a full revolution in about 365 days – one year on Earth. Mars is a little slower, and farther from the sun, so a full circuit takes 687 Earth days – or one Mars year.

Answer:

A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
