Answer:
DNA: TTAAGCCCCAAA
RNA: UUAAGCCCCAAA
Explanation:
A binds with T (Apples on Trees)
C binds with G (Cows eat Grass)
So complementary sequence would be TTAAGCCCCAAA
For RNA sequence:
For RNA:
A binds with U
T binds with A
C binds with G
So RNA complementary will be UUAAGCCCCAAA
Answer: false
Explanation: Polyester is hydrophobic. For this reason, polyester fabrics don't absorb perspiration, or other fluids, leaving the wearer with a moist, clammy feel. Polyester fibers typically have a low level of wicking. Relative to cotton, polyester is stronger, with a greater ability to stretch
A.
preventing fish from moving along a river.
B.
serving as a place for people to have picnics.
C.
increasing fresh water sources for humans.
D.
providing new wildlife habitats.
Answer:
A. Preventing fish from moving along a river.
Explanation:
1. Dams create barriers and trap the water that builds up behind it. This prevents fish from moving along the river as there's a barrier in place and is just overall harder for the fish to move freely along a river because of it.
2. It's the only negative option as the others are all positive outcomes, while the question asks for a negative outcome instead.
Hope this helps!
Answer:
Biological membranes have three primary functions: (1) they keep toxic substances out of the cell; (2) they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products, that mediate cellular and extracellular activities to pass between organelles and between the cell and the outside environment; and (3) they separate vital but incompatible metabolic processes conducted within organelles.
Answer:
during external respiration
Explanation:
Oxyhemoglobin is a type of hemoglobin carrying oxygen which is bright red in color. In the blood, it's major function is to carry oxygen molecules throughout the body.
Oxyhemoglobin is formed during external respiration. External respiration also known as breathing occurs in the lung. During external respiration, there is an exchange of oxygen and carbon-dioxide between the cells of the body and blood vessels. During breathing, oxygen diffuses into the blood, the oxygen then binds with heme in the hemoglobin found in erythrocytes to form oxyhemoglobin.
Answer:
during external respiration
Explanation:
Oxyhemoglobin is a protein formed when hemoglobin is combined with an oxygen molecule during lung respiration, also called external respiration. Its function is to transport oxygen throughout the body.
External breathing is performed when we breathe in oxygen into the body. This oxygen will be used for cells to perform cellular respiration that will be responsible for exhaling carbon dioxide out of our body.
