An experiment is set up to determine if wheat grows better when it is planted by itself or together with clover. The setup involves 3 pans of each treatment. Set-up A, B and C contain wheat alone. Set-ups D, E and F contain clover and wheat planted together, in rows alternating one seed of each type. One hundred seeds are planted in each pan. all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. Use Passage 1-1. Constants in this experiment are:

Answers

Answer:

The constants in this experiment are:

Number of planted seeds

Soil type

Pan size

Temperature

Amount of sunlight

Explanation:

Both treatments the only variable is the absence/presence of clover, so then the other parameters remain as constants due to these do not change their size or amount for both treatments.

The gene that causes sickle-cell disease is present in a higher percentage of residents of sub-Saharan Africa than among those of African descent living in the United States. Even though this gene causes sickle-cell disease, it also provides some protection from malaria, a serious disease that is widespread in sub-Saharan Africa but absent in the United States. Discuss an evolutionary process that could account for the different percentages of the sickle-cell gene among residents of the two regions.

Answers

Ans.

Sickle-cell disorder is a genetic disorder, which shows defected red blood cells, due to mutation in the genes for hemoglobin protein.

Malaria is common in sub-Saharan Africa region and there, natural selection favored gene for sickle cells, because it might be beneficial to people having sickle cell disease that makes them able to survive in such condition and transmit their genes to offspring.

On the other hand, in those Africans, who moved to United States, where malaria is uncommon or absent, natural selection favored normal, wild type genes, resulting in fewer people with defected sickle cell.

Hence,  sub-Saharan African population shows higher percentage of mutated gene for sickle cell as compared to population of United States.

Thus, the evolutionary process behind this difference is 'natural selection.'

Which structures, if found in a cell, would provide the best evidence that the cell is eukaryotic?

Answers

Answer:

internal membranes

Explanation:

Eukaryotic cells are represented by animal and plant cells, which are cells that have internal membranes, that is, nuclear membranes. Eukaryotic cells have a nucleus, which separates the DNA from the cytoplasm. This nucleus is bounded by a membrane, the nuclear membrane, also called the inner membrane.

Unlike eukaryotic cells, prokaryotic cells do not have internal membranes, do not have a delimited nucleus and the DNa is exposed to the cytoplasm.

Explain why scientists should welcome evidence and arguments that contradict accepted scientific theories?

Over time, science has never based there theories on assumptions. It must have been tested severally before the acceptance of such theories but every scientific submissions must be criticized which gives room for improvement in science.

Science is like an object in motion, there is always advancement day by day. So evidences with general perceptions would be greatly welcomed and tested virtually using every necessary tools in order to validate the authenticity.

Before anyone would criticize, such scientist must have tried the earlier theory severally and prove it to be wrong by providing answers that arises from such questioning, this birth another way forward that scientists in that field take as challenge to work on it and either oppose the earlier theory stated or validate the authenticity of the criticized theories
