Answer:
None of the above are correct.
Explanation:
<em>The two scientific names; Agkistrodon contortrix and Austrelaps labialis have nothing in common in terms of both generic and species names. That both have 'copperhead' in their common name also does not necessarily mean that the two snakes are closely related.</em>
Hence, none of the options is correct.
The correct answer is: 2)The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.
<span>Synthetic cathinones, more commonly known as "bath salts," are synthetic drugs chemically related to cathinone, a stimulant found in the khat plant. Khat is a shrub grown in East Africa and southern Arabia, and people sometimes chew its leaves for their mild stimulant effects. Synthetic variants of cathinone can be much stronger than the natural product and, in some cases very dangerous. This the correct answer :)</span>
Answer:
Epidermis layer of the skin will be most affected and blisters indicates that dermis layer of skin has also been affected.
Explanation:
The sunlight contain ultraviolet radiations which can damage the skin. The UV radiations causes serious damages to DNA and other parts of the cells directly and also by the production of free radicals. These radiations damage the DNA and cell tries to rectify them. These damages to DNA causes problems in cell replication through errors in DNA replication. If the damage is too frequent that cell can't repair it the immune response will destroy the cell.
Epidermis is the outermost layer of skin which protect the internal cells from external damages and dermis is present beneath the epidermis and it provides nutrient rich blood to epidermis. If the UV radiations are too intense they can penetrate more deeper and can damage the dermis also.
Skin burn can occur in less than 15 minutes depending upon the intensity of UV radiation. The skin become red and blisters appeared on skin. More chronic skin burn can also cause fever, chills and even death.
When limiting factors increases, diversity in population decrease.
