Answer:
The thorns on a rose bush.
The white coat of a snowshoe hare.
The speed of a gazelle.
Explanation:
Defense mechanisms are the adaptations and modifications in a living organism to counterattack or provide a defense in response. Some modification in the plant and the animals helps them to provide a counterattack to save themselves from the attack. The defensive function of the thorns in the roses helps them from being eaten or crushed. Snowshoe hares have furry feet that are large. The white fur helps them to camouflage during winter in the snow and be safe from the predators. Gazelle is an antelope found in South Africa that is able to make long jumps and make sharp turns while running and saving itself from the predators.
Answer:
The correct answer is option A) "0.0 mM sucrose".
Explanation:
Since single-celled Paramecium use their contractile vacuole to osmoregulate upon hypotonic environments, it is expected that a condition where no sucrose or salt is added is the condition where the contractile vacuole would be most active. In this extremely hypotonic condition cells tend to absorb high quantities of water, the contractile vacuole pumps water out of the cell to regulate its osmotic pressure.
The correct answer is option 4, that is, ATP and NADPH are produced.
The light-dependent reactions refer to an array of biochemical reactions in the process of photosynthesis, which need light energy that is captivated by the light-absorbing pigments like chlorophyll. The light-dependent reactions occur in the thylakoid membranes of the chloroplast.
The light-dependent reactions use energy in the form of light to produce two molecules required for the next phase of photosynthesis, that is, the energy storage molecule ATP and the reduced electron carrier NADPH.
Answer:
genes are the basic sequence of DNA that controls the traits of an organisms.
Explanation:
genes have nucleotide sequences. these sequences are involved in transmission of characters from one generation to other. if their is an error occur in this sequence the new offspring will b dissimilar from parent in this secific character which chnaged.
central dogma is the basic process through which genes are controlling the traits. first step is transcriotion through which DNA or gene is transcribed into mRNA sequence. then the second step is translation in which mRNA is translated into protein. in this way by making proteins genes control the traits or functiong of a body.
