The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
Answer:
Codominance
Explanation:
Codominance is the condition in which both the alleles of a trait are dominant and are equally expressed when comes together in the offspring. For example in ABO blood grouping in humans A and B allele are dominant so when they both come together in an offspring then they produce AB blood group in that offspring.
Here when true-breeding strains of salamander having yellow and red stripes are crossed together they produce offsprings having both yellow and red stripes that shows that the traits are codominant.
Therefore the pattern of codominance is most consistent with this observation.
Answer: energy
Explanation:
Biodiversity can be defined as the variety or variability of species of flora and fauna in an ecosystem. A larger number of plant species or flora contributes to the greater variety of crops also some of the animal or faunal species are source of food for human beings.
The biodiversity involves the distribution of energy in the form of food in an ecosystem. This circulation is facilitated by the food chain when one organism is consumed by the other. Thus the direct ecosystem service of biodiversity is the distribution of energy among the organisms.
Asexual reproduction means that the cell has "cloned" itself, and will therefore have the same number of chromosomes as its daughter, thus option B is correct.
Answer:
The correct answer is lysosomes
Explanation:
Tay-Sachs disease is a genetic metabolic disorder in which a lipid called GM2 ganglioside builds in the brain which results in spasticity and death in childhood.
This disease is also known as lysosomal storage disease. Lysosomes are the major organelle that contains enzymes to breakdown molecules. In Tay-Sachs disease deficiency of hexosaminidase A occurs in lysosomes and this enzyme is needed to breakdown fats.
So due to this deficiency, it results in the accumulation of fats in the brain and spinal cord causing Tay-Sachs disease.
