Explanation:
Chloroplasts are necessary for plant cells to get energy. Plants are autotrophs, which means that they need to make food/energy by themselves to survive, and plants do so using a process called photosynthesis that chloroplasts aid in. Both plant and animal cells have a nucleus, cell membrane, and mitochondria, but only plant cells have chloroplasts. Therefore C.

Assume a cell has a membrane potential of -70 mV and a Cl- equilibrium potential of -81 mV. If the cell membrane is permeable to Cl-, will there be net movement of Cl- into or out of the cell? Explain.
Answers
Answer:
Cl- ions will move inside the cell.
Explanation:
When the equilibrium potential and is equal to membrane potential, the net charge across the membrane is equal to zero and therefore there is not movement of ions across the membrane. However, in this case, the membrane potential is -70 mV, while the equilibrium of negatively charged Cl- ions is -81 mV. In consequence, Cl- ions will tend to move inside of the cell.

The main 2 types of nerves are sensory nerves and motor nerves:
1. Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation.
2.Sensory nerves also known as afferent nerves, carry impulses from sensory receptors towards the brain.
3.Motor nerves also known as efferent nerves, carry impulses away from the brain to muscles and glands.

Which is the property of nonmetals to evaporate easily?
brittle

liquid
volatile
Answers
Explanation: Nonmetal are usually volatile, which means it evaporate easily.
Volatile is the property of nonmetals to evaporate easily. The correct option is D.
What is being volatile means?The ease with which a material vaporizes is described by its volatility. A volatile material is defined as
A compound that readily evaporates at normal temperatures.One with a measurable vapor pressure. Basically, the term volatile refers to liquids.Volatility is a substance quality in chemistry that characterizes how easily a material vaporizes.
An active ingredient with high volatility is more likely to exist as a vapor at a given temperature and pressure, whereas a substance with low volatility is more likely to exist as a liquid or solid.
The enthalpy of vaporization describes the temperature dependence of the vapor pressure, while vapor pressure is the physical property that conveys a compound's volatility at a given temperature.
Thus, the correct option is D.

One method for separating polypeptides makes use of their different solubilities. The solubility of large polypeptides in water depends on the relative polarity of their R groups, particularly on the number of ionized groups: the more ionized groups there are, the more soluble the polypeptide. Which of each pair of polypeptides that follow is more soluble at the indicated pH?
(a) (Gly)20 or (Glu)20 at pH 7.0
(b) (Lys–Ala)3 or (Phe–Met)3 at pH 7.0
(c) (Ala–Ser–Gly)5 or (Asn–Ser–His)5 at pH 6.0
(d) (Ala–Asp–Gly)5 or (Asn–Ser–His)5 at pH 3.0
Answers
Answer
The answers are below:
1.
(Gly)20 or (Glu)20 at ph 7.0
The answer is (Glu)20 because at a pH of 7 it has high negative charges so (Gly)20 is less soluble since it would remain unchanged
2.
Lys–Ala)3 or (Phe–Met)3 at pH 7.0
The answer is (Lys-Ala)3 because it has high positive charges at this pH while (phe-met)3 is lower this it is less soluble.
3.
Ala–Ser–Gly)5 or (Asn–Ser–His)5 at pH 6.0:
(Asn–Ser–His)5 is more soluble because though both of these polymers have the side chain Ser, (Asn–Ser–His)5 also have polar Asn side chain also it's His side chain is partially proponated.
4.
(Ala–Asp–Gly)5 or (Asn–Ser–His)5 at pH 3.0:
(Asn–Ser–His)5 is more soluble at ph of 3. this is because Asp residues are not fully proponated and they are also neutral, while (Asn–Ser–His)5 has its His residues fully proponated and also positively charged.
A group of 250 women over the age of 40 are recruited for a study to determine the effects that calcium has on bone health. Half of the participants are given a calcium supplement and the other half are given a placebo. If 13 women on calcium develop osteomalacia and 27 women not on the placebo develop osteomalacia, the relative risk for developing osteomalacia for women over 40 on a calcium supplement is 0.48 when compared to those women not taking a calcium supplement. This indicates that taking calcium has no effect on the population of interest's health because the relative risk is less than 1.0.
A. True
B. False
Answers
Answer:
A. True
Explanation:
The result indicates that taking calcium has no effect on the development of osteomalacia in the women. This is because, of the over 120 women placed on the calcium supplements, it happens to be minimal number of people ( less than 20 people) that develop the osteomalacia disease of the bone.

Gases from volcanic eruptions increase global temperature. The correct option is A. When volcanoes release greenhouse gases into the atmosphere the climate gets warmer.
What are the gasses involved in volcanic eruptions?
Many gases dissolved in magma are released during volcanic eruptions.
The most significant ones are water vapor, carbon dioxide, carbon monoxide, oxides of sulfur, hydrogen, nitrogen, fluorine, chlorine, boron, and arsenic.
Many of these gases are closely involved in the greenhouse effect, causing an increase in global temperature.
The emission of gases by volcanic eruptions is a natural process that might increase atmospheric pollution.
The correct option is A. When volcanoes release greenhouse gases into the atmosphere the climate gets warmer.

Another step in PCR requires small single-stranded DNA primers to anneal to a target sequence on denatured DNA. Two primers are used. Ideally these primers will have similar melting temperatures. The melting temperature is defined as the temperature at which 50% of the DNA is in the single-stranded form. Which of the following primers will have the highest melting temperature?
A. GGGGAAATTTCCCC.
B. AAAAGGGCCCTTTT.
C. AAAAGGCCTTTT.
D. GGGAAATTTCCC.
Answers
Answer:
A. GGGGAAATTTCCCC.
Explanation:
When calculating the melting temperature in the DNA primers, we use the formula:
( 2 × ( A + T ) ) + ( 4 × ( G + C ) )
From the above formula; it is obvious that G and C have a greater tendency of participation when determining which DNA primers that have the highest melting temperature.
A. GGGGAAATTTCCCC = 8
B. AAAAGGGCCCTTTT = 6
C. AAAAGGCCTTTT = 4
D. GGGAAATTTCCC = 6
From the given options, we can see that option A have the highest component of G and C.
