Y = yellow leaves
y = greed leaves
S = smooth seeds
s = rough seeds
The presence of the dominant traits (the capital letters) dictates that the plant has yellow leaves and smooth seeds.

Answer:
False. Bone can be classified as a connective tissue because it provides support and structure to the body.
Explanation:
Connective tissue is those tissues that fill spaces between organs and other tissues, and also provide support to the organism. It is characterized by the presence of different types of cells separated by intercellular material synthesized by them.
The bony tissue is the principal structural and supportive connective tissue that differs from the other connective tissues because its extracellular matrix is mineralized, which makes it possible to accomplish its support and protection function due to its rigidity and hardness. The mineral that deposits in the osteoid matrix is the calcium phosphate, composing hydroxyapatite crystals. The bony tissue is a storage site of calcium and phosphate, which are available for maintaining constant the calcium blood levels according to the individual physiological needs.
<u>Answer:</u>
<em>Biomagnifications largely affects the organisms at the highest trophic level.
</em>
<u>Explanation:</u>
The increase in concentration of toxic chemicals while moving up in a food chain is called biomagnification. What starts out as a small concentration at the lowest trophic level turns out to become a <em>higher concentration at higher trophic levels. </em>
Thus it is the organisms at the highest trophic level that are the most affected. This accumulation occurs because the organisms have not evolved enough to posess mechanisms that <em>facilitate detoxification of various substances. </em>
Such substances are called novel substances and DDT is an example. Removal of substances like metals is also difficult. Thus a harmful chemical component travels up various trophic levels increasing in <em>concentration at each trophic level.
</em>

Answer: The scientist was repeating the experiment to improve the validity of her data.
Explanation:
<u>The scientific method involves the observation of natural phenomena and then the postulation of hypotheses and their testing by experimentation</u>. The knowledge we have represents scientific hypotheses and theories supported by observations and experiments (empirical method).
Experiments are performed to support/validate or refute one or many hypothesis. Several experiments provide insight into cause-and-effect by demonstrating what result occurs when a particular factor is manipulated.
A scientific hypothesis is an acceptable proposition that has been formulated through the collection of information and data, although unconfirmed, serves to provide an alternative answer to a scientifically based problem. Also when a research work is carried out, a conclusion should be drawn, which in these cases is an argument or statement that synthesizes the work done. The main ideas are taken and the research is summarized, explaining in the author's own words the reason for the results obtained. In the case of a discussion, the personal point of view of each of the members that participated in the experiment are exposed.
Since the scientist repeated the previous experiment to improve the validity of her data, that justifies the fact that she skipped the hypothesis and experiment. With the first results of the experiment, I formulate a conclusion. Then, with other results of the same experiment, he formulated another conclusion. So there is no need to repeat the experiment, because it is the same.
