Biological systems do not contradict the second law of thermodynamics. Even in this case, entropy is still always increasing. Biological systems can only decrease their own entropy by using copious amounts of energy and by increasing entropy in their surrounding environment. Also, unfavorable anabolism reactions are always paired with more favorable reactions, such as the use of ATP in order to make the overall Gibb's free energy of the reaction negative.
Answer:
A point mutation can be described as a mutation in which changes occur in a single nucleotide. A nucleotide may get changed, deleted or inserted from the sequence of DNA. Point mutations can be harmless or harmful depending on the nucleotide in which the changes occur.
A change in just one nucleotide can result in the formation of wrong amino acid and hence changed or wrong proteins can be formed. If the original protein was involved in cellular reproduction, then the entire process of reproduction can be affected by a point mutation.
Sickle- cell anaemia is a disease in which the body fails to produce enough healthy red blood cells. This disease occurs due to point mutation. Point mutation occurs where glutamine (GAG) of the β-globin gets changed into valine (GUG). This change causes the haemoglobin to get a deformed structure due to which it is not able to carry out oxygen.
The whole landform will slowly be eroded as well , because of the ocean waves eroding it
Answer:
A. double-blind
Explanation:
Based on the scenario being described within the question it can be said that the type of trial that she has joined is known as a double-blind study. This is a type of study in which individuals are chosen randomly for each clinical intervention and the results are not given to the researchers until after the trial. This also includes any and all information that may influence the researchers behavior or thoughts on the study.
A letter indicates an articulating surface that is comprised of hyaline cartilage.
<h3>What is
hyaline cartilage?</h3>
- The synovial joints include hyaline cartilage, which facilitates joint motion.
- Chondrocytes and extracellular matrix make up its structure.
- The organization of the extracellular matrix, which determines the biomechanical characteristics of cartilage tissue, is greatly influenced by chondrocytes.
- Hyaline cartilage covers the ends of the bones where they come together to create a joint.
- In a typical healthy joint, this cartilage is bluish white and shiny.
- Its main job is to reduce friction and act as a little cushion between the ends of the bones.
