A nucleotide has 6 carbon sugars. True or false
Answers
The given statement "A nucleotide has 6 carbon sugars" is a false statement as nucleotides have pentose or 5- carbon ribose sugar in their composition.
A nucleotide is a compound that is connected to other nucleotides together to form structures of nucleic acids that are RNA and DNA. These compounds have three components linked together to form it, that are:
Nitrogenous basephosphate grouppentose sugar or 5-carbon sugarsIn DNA these pentose sugars are called deoxyribose and in RNA these pentose sugars are called ribose due to the presence of the -OH group on the 2' carbon of the ribose in RNA.

What are some advantages and disadvantages of using wind energy to
create electricity?
Answers
Answer:
Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy
Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats
Explanation:
Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.

What do many ecologists feel is necessary for an area to be classified as a forest?
a.) several species of trees
b.) enough trees to create a close canopy
c.) consistent warm weather
Answers
Answer:
B. Enough trees to create a close canopy.
Explanation:
Forests may have several tree species but one very important feature of forests is their close canopy of dense trees, often arranged in several strata (or layers).
The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.
What is the use of sunlight?Sunlight must be remembered that sunlight has the vital element for the plant survival without it the photosynthesis that cannot take place, or it will not be as the efficient as it would be if there was the full access to the sunlight. Sunlight activates the electrons on the chlorophyll and with that a plant has able to produce the ATP, which has the basic energy-producing unit in any living cell.
As such in the dense forests where we have tall and the shorter, trees, those that reach the highest point of the canopy have the access to most of the sunlight, while the shorter ones have to make do with whatever filters through the branches of the others.
Thus by not having as much access to sunlight, their photosynthetic processes are not as efficient. Those that adapt to lesser amounts of light, will survive, but the others would not.
Therefore, The reason why in forests shorter trees do not survive as well as trees that reach the top of the canopy, would be light distribution and access to sunlight.

The fossil record reveals that the diversity of flowering plants and the diversity of certain insect groups increased at the same time. How might you explain this?
Answers
Answer:
Insects and flowers are connected with each other for several life purposes such as for food, habitat and pollination.
The cause of diversity in flower and insects is associated with the process of pollination. In the process of pollination, both insects and flowers are mutually get benefits.
Insects move flower to flower in search of food and in the process it also carry pollen from flower to flower as well. Through insects the pollen reaches to different flower and show diversity and at the same time insects feed on various types of flowers and reproduce generation with variations.
Hence, the process of pollination makes a relationship between flower and insects diversity at the same time.

B. B Energy flows from producers to one or more levels of consumers.
C. C Consumers transfer their energy to producers.
D. D Decomposers get their energy directly from the sun.

Explanation:
Energy flows from producers to one or more levels of consumers. Think of it this way:
A banana tree grows in the forest.
A monkey eats the bananas off of the tree, it now consumes the energy provided by the banana.
(whatever animal kills monkeys) kills the money for food, they have now consumed the energy of the monkey, as well as the banana the monkey has eaten previously.
The web continues, and energy continues to be distributed to each level of consumer, all starting with a single producer.

Answers
Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
Explanation:
The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. Homologous chromosomes are present in the meiosis I, but not in meiosis the II. After pairing up of in the prophase I, homologous chromosomes are able to exchange some corresponding segments and a cross-over occurs. Thanks to the cross-over event, each chromosome will have a new combination of genes. Without this, parents will produce gametes with only two different gene combinations.
Answer:
Chromatids of homologous chromosomes exchange corresponding segments.
