Answer:

algal growth due to eutrophication

Explaination:

Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.

Identify the highlighted artery. Identify the highlighted artery. right coronary marginal circumflex left coronary

Highlighted artery is right coronary.

<h3>What is artery?</h3>
  • The blood channels that carry oxygen-rich blood from the heart to the body's tissues are called arteries.
  • Each artery consists of three layers and is a muscular tube bordered by smooth tissue.
  • The endothelium, a smooth tissue, lines the intima, the inner layer.
  • Blood is transported from your heart through arteries.
  • All body parts have arteries, with the exception of the hair, nails, epidermis, cartilages, and cornea.
  • In the limbs, they run along the flexor surface, where they are less vulnerable to injury, and the larger trunks typically occupy the most protected positions.
  • A conduit that carries blood from the heart to the body's extremities is called an artery.
  • Every artery, with the exception of the pulmonary artery, carries oxygenated blood.
  • The ascending aorta, aortic arch, thoracic aorta, and abdominal aorta are the four divisions of the aorta, which is the biggest artery in the body.

Write a five sentence paragrgh explaining the cell cycle
Nady [450]

Answer:

The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.

New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.

The two main parts of the cell cycle are mitosis and interphase.

Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”

The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.

Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.

Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.
