Explanation:
The absorbed light energy by plants is then used to change the carbon dioxide into sugar that plants can use or store as ______.
Answer:
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.

3. If 98 out of 200 individuals in a population express the recessive phenotype, what percent of the population
are heterozygotes?
Answer:
Explanation:
Q:
If 98 out of 200 individuals in a population express the recessive phenotype, what percent of the population would be heterozygotes?
A:
0.42 or 42%
The recessive phenotype is the phenotype that is expressed only when the recessive condition is found in both alleles.
The percent of the population that would be heterozygous is 42%
If 98 out of 200 individual express the recessive allele = 98/200 = 0.49. This is the phenotypic frequency of the recessive allele (q²)... q = 0.7 (√0.49)
Since p + q = 1
1 - 0.7 = 0.3 = p
To find the percent of heterozygous...p² + 2pq + q² = 1
Where 2 x 0.3x0.7= 0.42
Therefore, the percent of the population that are heterozygous is 42%

Which of these statements is true?
A. Species do not interact with each other in the course of succession.
B. During succession, new species move into an area and colonize it, and are later replaced by newer species.
C. Most ecological successions occur over 10 to 15 years.
Answer:
Opt B is the right ans....ig this is according to the charles darwins theory...survival of fittest
The true statement is "During succession, new species move into an area and colonize it, and are later replaced by newer species. Thus, the correct option is B.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over time.
Succession is always taking place by the better competitor. In the bare area, new species arrive, stabilize themselves, and colonize themselves.
After a specific period of time, new species are replaced by them, and now they got stabilized in the same area. This cycle of succession gradually works in a similar manner.
Therefore, the correct option is B.

Which of the following does not occur in an aquatic ecosystem as a result of nutrient loading?
a. acidification of the water
b. algae growth as a result of eutrophication
c. degraded quality of water for human and livestock consumption
d. improved water habitats for human recreation
Answer:
D
Explanation:
Overdosing on nutrients, especially nitrogen and phosphorus, can act as fertilizer and promote an excessive quantity of algae development in water bodies. Thus, option C is correct.
What is nutrient loading?Eutrophication, a process wherein water bodies get an excessive amount of inorganic nutrients, mainly N and P, promotes an excessive growth of plants and algae, is caused by nutrient enrichment in aquatic water bodies.
The calculation of annual loads involves multiplying daily flow by daily nutrient concentration and averaging throughout the course of the year.
Since samples were only taken once a week at most, daily concentration measurements are not available; therefore, daily concentration data must be entered to calculate loads.
Therefore, improved water habitats for human recreation.

Which came first? The chicken or the egg?
Answer:
i mean the chicken woulda had to come first to lay the egg in the first place
Explanation:
Answer:
According to scientists chicken CE first because chicken are developed form of dinosaur
and dinosaur also lay eggs. But technically egg came first because The oldest fossils of dinosaur eggs and embryos are about 190 million years old. Archaeopteryx fossils, which are the oldest generally accepted as birds, are around 150 million years old, which means that birds in general came after eggs in general.
What did the comparative study on chytridiomycosis teach scientists studying white-nose syndrome in bats?Select one:a. Humans were responsible for the spread of chytridiomycosis, but not white-nose syndrome.b. A novel fungal infection could spread to colonies and cause dramatic population crashes, as seen in the comparative study.c. Chytridiomycosis affected only certain amphibians, so the comparative study could not teach the scientists anything useful.d. White-nose syndrome affects bats but does not cause death in organisms like chytridiomycosis does in amphibians.e. It was probably not a fungal infection affecting the bats and scientists needed to look elsewhere for a cause.
Answer:. A novel fungal infection could spread to colonies and cause dramatic population crashes, as seen in the comparative study
Explanation:
fungal diseases of wildlife, amphibian chytridiomycosis and bat white-nose syndrome are diseases in bat that have emerged rapidly and unexpectedly over the past several decades.
These diseases have lead to unprecedented local and global decrease in population of amphibian and bat species the infection colonize their territory and pose serious threats to biodiversity and ecosystem stability due to loss of many of them.

What is anabolism? Give an example. What is catabolism also give an example
Answer:
Anabolism is the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy.
Examples of anabolism: bone growth and mineralization, and muscle mass build-up.
Catabolism: the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy.
Examples of Catabolism: glycolysis, the citric acid cycle, the breakdown of muscle protein in order to use amino acids as substrates for gluconeogenesis, the breakdown of fat in adipose tissue to fatty acids, and oxidative deamination of neurotransmitters by monoamine oxidase.

What is a sustainable future?If a society wants to make use of materials which can be recycled, then it has good plans for building a sustainable future for itself as it would be self-dependent and not have to rely on other nations.
With this in mind, if a country wants to build a sustainable future for itself, then it would have to use local resources more because this would increase self-sufficiency and reduce dependency.

Have an amazing day!!
Please rate and mark brainliest!!
Answer:
When at least one allele contains instructions for a long tail
Explanation:
Gregor Mendel discovered that an organism receives two forms of a gene called ALLELE for a particular trait. Each allele encodes or represent a different trait in that same gene. However, according to Mendel, one allele called DOMINANT allele is capable of masking the expression of the other allele, called RECESSIVE allele. This means that in a heterozygous state i.e. combination of the two different alleles, the dominant trait encoded by the dominant allele will always be expressed.
