Answer:
D (3/4)
Explanation:
This cross involves a single gene coding for flower colour in pea plant where the purple allele (P) is dominant over the white allele (p) since the purple allele masks the expression of the white allele in a heterozygous state (Pp). A cross between two heterozygous plants (Pp) will produce four possible offsprings with genotypes PP, Pp and pp in the ratio 1:2:1.
The PP and Pp genotypes are purple flowered while the pp is white flowered. Hence, the probability of having purple flowered plants from this cross is 3 out of 4 i.e. 3/4.
<span>Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative. Electropositive elements such as metals like to give up electrons, thus taking on a positive charge. Electronegative elements such as chlorine attract electrons, so they become negative. When electropositive and electronegative atoms meet and exchange ions, they take on opposite charges. Because positive and negative charges attract, these charged atoms become attracted to one another. This attraction forms an ionic bond that keeps the ions together.</span>
Answer:
<u>Short paragraph:</u>
Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.
<u>Long paragraph:</u>
The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.
<u><em>-Why does the lysosome have a different pH than the cytoplasm? </em></u>
The pH within lyosomes is more acidic than the pH of the cytoplasm because Enzymes within the lysosomes aid the breakdown of proteins, polysaccharides, lipids, nucleic acids, etc. These enzymes are active at a much lower pH than that of the cytoplasm. Thus the different pH from the cytoplasm.
<u><em>-What is the advantage of having several smaller chloroplasts and not just 1 huge one?</em></u>
The advantage of having several smaller chloroplasts and not just 1 huge one increases the surface area for the light to be absorbed. As a result, more light energy can be utilized.
