<span>This question can be solved using Hardy-Weinberg equation. The equation would be:
a+b=1
</span>a^2+2ab+b^2=1
<span>There are 360 individual with genotype bb which means
b^2=360/1000
b=</span>√0.36= 0.6
The frequency of b allele would be: 0.6
Answer:
Thyroid hormones
Explanation:
Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have shown to be affected by their effect on the thyroid. These chemicals can produce endocrine alterations acting as thyroid disrupters. They affect many mechanisms in the organisms such as inhibition of thyroid iodine uptake, <u><em>interference with the thyroid hormone receptor</em></u>, binding to transport proteins, among others. They cause toxicity in the functioning of the hypothalamic-pituitary-thyroid axis.
There are many studies that associate thyroid diseases with exposure to organochloride pesticides. Significant alteration in the TSH, T3, and T4 levels have been expressed by people directly or indirectly exposed to the chemicals.
Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
Answer:
Option-D
Explanation:
Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.
The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.
The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.
Thus, Option-D is the correct answer.
Answer:
The correct option is B) analyze the results and make a conclusion
Explanation:
The scientific method of research is based on the following steps:
Observations are made: In the following scenario, a student observed that t when bananas are kept near other fruits, the other fruits ripen faster.
Question: Based on the observation, a question is generated. In this scenario, the student had a question that will keeping bananas near any fruit increase the ripening process of the fruit.
Hypothesis: A hypothesis is the formation of a tentative statement.
Experiments: Based on the hypothesis, experiments are done to check for the results.
Analyzing the results and drawing conclusions: Results from the experiments are analyzed and conclusions are drawn which might prove the hypothesis to be correct or wrong.
