Alternative methods of producing energy are more efficient than burning fossil fuels. Fossil fuels emit carbon dioxide and other harmful gases to the environment which cause domino effects such as global warming. When the atmosphere warms, the ice melts near the poles and causes the ocean levels to rise. When the ice melts animal's ecosystems are also destroyed. Alternative energy sources can help us sustain our lives in the future. At the rate we burn fossil fuels, we will run out soon. Alternative methods are much safer for us, other animals, and the environment.

19. Interphase

20. Interphase

21. Prophase

22. Interphase

Explanation:

The cell cycle is divided into two main divisions. The Interphase ad the M phase or the Mitotic phase.

Throughout Interphase, the cell is not dividing yet, but it is preparing to divide. It synthesizes the nutrients it will need, and grows in preparation to become two cells. This is actually the phase the cell spends the longest time.

Mitotic phase is when the cell starts to divide. It is separated into:

Prophase:

In this phase the chromosomes are condensed and mitotic spindles start to form. These spindles are made up of microtubules that will help later on to split the chromosomes. The nuclear membrane disappears so that the chromosomes will be free to move.

Metaphase

This phase is marked by the alignment of the chromosomes in the middle of the cell. They line up and you will find the asters at the opposite ends of the cell, where the microtubules stem from, attaching themselves to the center of the chromosomes, which we call the kinetochore.

Anaphase

In this phase you will see that the chromosomes are separated by the spindle fibers and are pulled at opposite ends of the cell. The cell then becomes longer by the other spindle fibers that are not attached to a chromosome.

Telophase

This phase is the end phase. The two sets of chromosomes are then enclosed by new nuclear membranes forming two nuclei and other cellular structures just as the cells are about to separate completely. As the two new cells move further apart, in plant cells a cell plate forms, dividing the two cells. The movement of the two cells splitting apart is called cytokinesis and it happens just as mitosis is about to end.

Attached is a picture of the cell cycle of a plant cell.

The term ""biomagnification"" means that a chemical ____ at each trophic level in a food chain or web.
Tasya [4]

Answer:

Increases

Explanation:

Biomagnification refers to a phenomenon in which the harmful toxic chemical gest magnified or amplified or increases in the food chain trophic level.

The biomagnification is caused by the bio-accumulation of the toxic material in the organisms.

The harmful toxic chemical enters the food chain through eating like when the crops are sprayed with pesticides and insecticides runoff in the water. From there the toxic material enters the aquatic food chain like from the planktons to fish and then to vultures.

The organisms at higher trophic level die because of the accumulation of the infected lower trophic organisms.

Thus, Increases is the correct answer.

aivan3 [116]

Answer:

Cooked Broccoli

Cooked Kale

Explanation:

Including Broccoli, all the vegetable of cruciferous family have cancer fighting properites. Specially for this purpose Broccoli is preferred because it has adequate amount of sulforaphane which is a potent compound that boosts the body's enzyme system and as a result of this the cancer causing chemicals can be flushed down easily by the body. Sulforphane also targets the cancer stem cells. These are the cells that promote the tumor growth.

During each heartbeat, about 80 g of blood is pumped into the aorta in approximately 0.2 s. during this time, the blood is accel
aivan3 [116]
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
                                   a = 1 m/s /  0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
                                  F = (80 g / 1000 g/kg) x (5 m/s²)
                                      = 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
