Answer:
2. Tuber
Explanation:
Reproduction is the process by which living organisms multiply themselves. They do this through two major ways namely: asexually and sexually. Sexual reproduction involves two organisms (male and female) that each donate a gamete (sperm and egg). In plants, the sexual reproductive structure is the FLOWER. The male flower is called STAMEN, while the female flower is called PISTIL.
However, plants can also be propagated asexually by making use of certain plant parts including tubers, leaf etc. TUBER is a structure in plant specifically used to asexually reproduce plants like yam, potato, cassava etc.
Answer:
Because the ocean reflects off of the sky so technically the sky is white but sense the sun causes the ocean to reflect onto the sky, the sky appears to be blue.
Explanation:
Answer:
D. Lots of vegetation
Explanation:
Urban heat islands form when cities replace natural land cover with dense concentrations of heat-absorbing pavement, buildings, and other surfaces. This has the impact of raising energy prices (for example, air conditioning), air pollution levels, and heat-related sickness and mortality.
Stomata play an important role in photosynthesis as they allow the plant to absorb carbon dioxide from the environment. In exchange, stomata allow oxygen, which is a waste product of photosynthesis, to be released. In the process, water vapor is also lost as the internal parts of the leaves are exposed. To reduce exposure, stomata are found on the underside of the leaves. They are protected from the sun as excessive heat can increase the rate of water vapor leaving and thus wither the plant. Stomata also have guard cells around the epidermis that close when too much water is being lost.
Answer:
C
Explanation:
A system is at equilibrium when the rates of opposing reactions are equal.
Answer A does not show the rate of reactions, it only shows concentrations of reactants.
Answer B only shows constants, it does not show rates of reactions.
