Answer:
a. Always independently stable. Domain
b. Retains native structure even when separated from the rest of the protein. Domain
c. β Barrel. Motif
d. Calcium-binding segments of calmodulin. Motif
e. An advantageous folding pattern composed of two or more secondary structure elements. Domain
f. Sometimes independently stable. Motif
Explanation:
a. Protein domains are evolutionary conserved and stable 3D structures formed by a series of amino acids joined by peptide bonds.
b. Domains are stable because they conserve their tridimensional structure in physiological conditions even if they are separated of the rest of the protein.
c. The ß-barrel motif is a type of motif localized in single-stranded DNA viruses.
d. Calmodulin is a protein that contains calcium-binding motifs that enable to sense intracellular calcium levels.
e. Domain folding patterns are critical transitional states that allow the proteins their interaction with specific ligands in different physiological conditions.
f. Motifs are sometimes independently stable, but due to their short length (3-15 amino acids), protein motifs are generally unstable in different conditions.
<h2>Wet versus Dry habitats</h2>
Explanation:
- Plants from wet habitats have a relatively large number of stomata and thin cuticle
- Plants from dry habitats have a less number of stomata and thick cuticle
- Stomata helps in exchange of gases whereas cuticle reduces the loss of water
- If water is more then plants have large number of stomata which helps in great access to water and increases support for herbaceous tissues
- In case of dry habitat conditions are not favorable with regard to water hence a thick cuticle is required to minimize the water loss while in wet habitat water is abundant hence they have a thin cuticle
A.Vascular plants have a relatively large number of stomata
B. Plants from wet habitats include white lotus,water lily
C. Plants from dry habitats include xerophytes for example cactus,oleander
The lake becoming ice is due to the water (freezing)
It’s number 1 - water is broken down into oxygen and hydrogens
Answer:
The second answer choice.
Explanation:
Genetic variation must be the answer as the plants were grown in the same conditions. Therefore, the only source of variability might be genetic variation.
The first choice is not the answer because Genetic factors cannot cause the environment around the plant to change.
The third choice is not the answer because the Environmental factors are the same, and if they were really to cause a mutation, all three plants would mutate.
The fourth is the same reason as the third: if environemnt conditions affected the flower, all three plants would change color since they were all grown in the same environemnt, not just the one we see in the results.
