Answer:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best
Explanation:
The hypothesis in an experiment is the testable explanation given in support of an observer problem. It is a predictive statement that aims at proferring a possible solution to a problem or answer a question asked. The hypothesis must be able to be tested via experimentation as this is one important feature all hypotheses must possess. A hypothesis is usually written in an "IF, THEN" format.
In this question, an investigation is being carried out to know the effect of a certain amount of fertilizer on the growth of orchids in a greenhouse. A possible explanation/hypothesis will be:
IF a high concentration of fertilizer is used, THEN orchid plants will grow best.
This can be accepted or rejected depending on the outcome of the experiment.
C. law of dominance
D. random segregation
E. independent assortment
Sexual reproduction promotes genetic variation. One way variation occurs is via the production of gametes during meiosis. Sexual organism are the product of sperm and egg, receiving chromosomes from both parents. But what mechanisms are at work during meiosis to promote genetic variation? Review the prompt and select all that apply
Independent assortment that promotes genetic variety is a chromosomal assortment and crossing over. Thus, options are -
(A) Crossing over
(D) Random segregation
(E) Independent assortment
During the metaphase stage of meiosis, the chromosomes align in the center, and either the mother's or father's chromosome has an equal chance of being transferred to the daughter's cell. The bigger the number of chromosomes in a karyotype, the greater the likelihood of gamete diversity.
During meiosis, homologous chromosomes cross across, allowing DNA fragments to be exchanged between sister chromatids. This results in variation.
Thus,
(A) Crossing over occurs when homologous chromosomes join up with non-identical twins and swap DNA sections.
(D) The distribution of chromosomes among four gametes is known as random segregation.
(E) Independent assortment entails the separation of a pair's homologous chromosomes into distinct gametes.

Answer:
The primary function of glucose in the cell is to produce energy instantly by catabolism. Glucose is the most common substrate and it yields two molecules of ATP directly from substrate-level phosphorylation.
hail
rain
snow
all of the above
Precipitation includes all forms of atmospheric water vapor that falls under gravity, including hail, rain, and snow.
In meteorology, precipitation refers to any product of the condensation of atmospheric water vapor that falls under gravity. This includes forms such as rain, snow, and hail. So, the answer to your question - Precipitation includes hail, rain, snow, or all of the above - is indeed, all of the above.
