Answer:
rough-skinned newts
Explanation:
The rough-skinned salamander, scientific name (Taricha granulosa) is a North American salamander known for the <u>strong toxin that exudes through its skin strong enough to kill an adult human</u>. Adults stay in ponds and lakes all summer and migrate back to the land in the fall, when the rain begins.
Its appearance is that of a rounded snout salamander, its color ranges from light brown to olive or brown-black at the top, with the bottom, including that of the head, legs and tail, with a yellowish orange contrasts with the brown top.
The diet consists mainly of a variety of invertebrates but also includes salanmandras and frogs, eggs and larvae and even small fish.
There is no picture shown, however details like this indicate that Scientist are examining the future changes in biodiversity within the Hudson river. If vegetation would see a continuous decrease, animals are forced to flee their habitat and find new areas or locations where they could thrive. When this happens, changes in the environment would put a great deal on the existence of certain forms of species within the area.
Answer and Explanation:
Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.
The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.
In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).
Answer:
Option D
Explanation:
Options for the question
A)import seeds produced in the southern hemisphere.
B)plant the flowers out-of doors in november.
C)keep the plants in a warm growing environment.
D)expose the plants to an hour of light in the middle of each night until the end of april.
Solution
Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.
Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time
Option D is correct
