Answer:
Renal cortex
Explanation:
The renal medulla of a kidney is surrounded by renal cortex. The renal cortex is the granulated layer. It is the renal cortex in which the renal corpuscle (glomerulus and Bowman's capsule) are present. The renal cortex is reddish brown in color. This is due to the fact that most of the renal arteries deliver the blood to the cortex.

A) Calcium Sulfide
It is used to demonstrate the importance of chlorophyll in photosynthesis. Plant with variegated leaves is de starched and then placed in the sunlight for a few hours, then the iodine test for starch is carried out. The green parts of the leaves will test positive for starch and therefore turn blue black. The non-green parts did not photosynthesize die to absence of chlorophyll and iodine color will remain brown.
Answer:
The correct answer is B 4 cells are formed,each having half the number of chromosomes as the original cell.
Explanation:
Meiosis is a specific type of cell division that occur in the germ cells.Meiosis is called reductional division because the 4 new cells those are produced after second meiotic division contain half the number of chromosomes as that of original cells.
During meiosis a cell undergo division two times the division that occur during first time is called first meiotic division resulting in the formation of 2 cells having 2n number of chromosomes.On the other hand the second meiotic division form 4 cells each having half the number of chromosomes.
Answer:
Two rocky material collision cause water formation
Explanation:
Earth is rich in water, and has been for a few billion years, but scientists are still debating just where all that life-sustaining liquid came from. At least some of it was thought to have been brought here by comets or asteroids, but that idea still falls short in explaining how so much water ended up on Earth’s surface – and deep below, as well. Now, a team of scientists at Arizona State University (ASU), led by Peter Buseck, has come up with a new proposal. The new peer-reviewed paper was published in the Journal of Geophysical Research: Planets on October 9, 2018.
The new research suggests that Earth’s water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun’s formation, called the solar nebula.

Earth’s ocean water is similar to that found in asteroids. That’s one reason scientists have long thought that most earthly water came from an asteroid bombardment in the days of the early solar system. The ratio of deuterium – a heavier hydrogen isotope – to normal hydrogen is a unique chemical signature in various water sources. In the case of Earth’s oceans, the deuterium-to-hydrogen ratio is close to what is found in asteroids. But, according to Steven Desch, also at ASU and one of the team members:
