explain how the structure of ATP relates to its function
Answer:
ATP functions as the energy currency for cells. ... The structure of ATP is that of an RNA nucleotide with three phosphates attached. As ATP is used for energy, a phosphate group or two are detached, and either ADP or AMP is produced. Energy derived from glucose catabolism is used to convert ADP into ATP.

Rising sea
levels lead to the migration of marshlands further inland. The environmental changes
caused by rising sea levels have the potential to?
O increase the stability of marsh habitats.
decrease the stability of marsh habitats.
O increase the biodiversity of organisms in marsh habitats.
alternately increase and decrease the biodiversity of marsh habitats.
Answer:
My Game is José Fernando Tengo 12 YEARS OLD
The environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.
What is Biodiversity?Sum total of all the varieties of living organisms in a particular space, is known as its biodiversity.
As the sea levels steadily rose, it will firstly increase the biodiversity of marsh habitats, but sea level constantly rising, will affect its biodiversity, and organism that is native to marshy habitat should be eliminated while those organisms that are able to survive in inland habitat will migrate into it, overall causing the decrease meant of biodiversity of marshy habitat.
Therefore, the environmental changes caused by rising sea levels have the potential to alternately increase and decrease the biodiversity of marsh habitats.

Describe the relationship between the sickle cell phenotype and hemoglobin’s structure and function
Answer: Explanation:
Sickle hemoglobin differs from normal hemoglobin by a single amino acid: valine replaces glutamate at position 6 on the surface of the beta chain. Therefore the red blood cell bends differently giving it a sickle shape
Answer:
Explanation:
Sickle cell disease is a group of disorders that affects hemoglobin, the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this disease have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape.
Signs and symptoms of sickle cell disease usually begin in early childhood. Characteristic features of this disorder include a low number of red blood cells (anemia), repeated infections, and periodic episodes of pain. The severity of symptoms varies from person to person. Some people have mild symptoms, while others are frequently hospitalized for more serious complications.
The signs and symptoms of sickle cell disease are caused by the sickling of red blood cells. When red blood cells sickle, they break down prematurely, which can lead to anemia. Anemia can cause shortness of breath, fatigue, and delayed growth and development in children. The rapid breakdown of red blood cells may also cause yellowing of the eyes and skin, which are signs of jaundice. Painful episodes can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels. These episodes deprive tissues and organs, such as the lungs, kidneys, spleen, and brain, of oxygen-rich blood and can lead to organ damage. A particularly serious complication of sickle cell disease is high blood pressure in the blood vessels that supply the lungs (pulmonary hypertension), which can lead to heart failure. Pulmonary hypertension occurs in about 10 percent of adults with sickle cell disease.

Why can mRNA leave the nucleus, but
DNA cannot leave the nucleus?
A. DNA is single stranded and is too long to leave the
nucleus.
B. RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.
C. DNA can leave the nucleus through special openings in
the nuclear membrane.
D. DNA and RNA can both leave the nucleus.
Answer:
B
Explanation:
Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.
Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.
mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.
What is DNA?DNA stands for Deoxyribonucleic acid. It may be characterized as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.
DNA is not a single-stranded structure. While RNA is present in a single stranded form in the cell. Due to this, the double-stranded structure of DNA seems longer than that of RNA to cross the nuclear membrane in the cell. As a result of this, RNA can easily leave the nucleus but DNA couldn't.
Therefore, mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

PHET skate park . Consider this equation: Kinetic Energy = ½ mv2. Which of those variables is changing as the skater moves up and down the track?
Velocity is the variable which is changing during motion of skater.
Impact of velocity on energyVelocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.
Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.
