Answer: D. Replacing thermal power plants.
Explanation:
Thermal Power Stations are some of the biggest users of water in the world because water is integral to producing electricity in them. These stations burn fossil fuels like coal which then vaporizes water so that it becomes steam which then drives turbines that produce electricity.
Water is also used for cooling high temperatures produced.
If these thermal stations are replaced with something that uses less water, it will go a long way in keeping the water debt less than the water supply.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M
Pretend you are a molecule of oxygen and you have reached the blood stream and attached to the hemoglobin on a red blood cell.
Describe as you travel through the different types of blood vessels (capillaries, arteries, and veins) as you make your journey through the different types of circulation (pulmonary/lungs, coronary/heart, and systemic/body) and reach the cells of the body.
Answer:
Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body. The journey might begin and end with the heart, but the blood vessels reach every vital spot along the way. These arteries, veins, and capillaries make for a vast network of pipes. If you were to lay out all the blood vessels of the body in a line, they would stretch for nearly 60,000 miles. That’s enough to circle the earth almost three times!
1. The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries
The different types of blood vessels and their layers
Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart. Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances. The capillaries also connect the branches of arteries and to the branches of veins. The walls of most blood vessels have three distinct layers: the tunica externa, the tunica media, and the tunica intima. These layers surround the lumen, the hollow interior through which blood flows.
2. Oxygenated Blood Flows Away from the Heart Through Arteries
The major arteries and branches of the body
The left ventricle of the heart pumps oxygenated blood into the aorta. From there, blood passes through major arteries, which branch into muscular arteries and then microscopic arterioles. The arterioles branch into the capillary networks that supply tissues with oxygen and nutrients. The walls of arteries are thicker than the walls of veins, with more smooth muscle and elastic tissue. This structure allows arteries to dilate as blood pumps through them.
3. Veins Carry Blood Back Toward the Heart
The superior and inferior vena cava
After the capillaries release oxygen and other substances from blood into body tissues, they feed the blood back toward the veins. First the blood enters microscopic vein branches called venules. The venules conduct the blood into the veins, which transport it back to the heart through the venae cavae. Vein walls are thinner and less elastic than artery walls. The pressure pushing blood through them is not as great. In fact, there are valves within the lumen of veins to prevent the backflow of blood.
4. Exchange of Gases, Nutrients, and Waste Between Blood and Tissue Occurs in the Capillaries
Click to play an animation of blood flow through capillaries
Capillaries are tiny vessels that branch out from arterioles to form networks around body cells. In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation. Elsewhere in the body, oxygen and other nutrients diffuse from blood in the capillaries to the tissues they supply. The capillaries absorb carbon dioxide and other waste products from the tissues and then flow the deoxygenated blood into the veins.
5. The Constant Pumping of the Heart Maintains Blood Pressure and Supply Throughout the Body
Click to play an animation of blood pressure measurement
The blood moving through the circulatory system puts pressure on the walls of the blood vessels. Blood pressure results from the blood flow force generated by the pumping heart and the resistance of the blood vessel walls. When the heart contracts, it pumps blood out through the arteries. The blood pushes against the vessel walls and flows faster under this high pressure. When the ventricles relax, the vessel walls push back against the decreased force. Blood flow slows down under this low pressure.

O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.

______ plants are important in fixing nitrogen.
a. Legume
b. Berry
c. Nut
d. Poisonous
Answer:
A
Explanation:
Legume plants are important in fixing nitrogen. Therefore, the correct option is A.
Beans, peas, lentils and clover are examples of leguminous plants that are important for nitrogen fixation. They co-exist well with rhizobia, a type of bacteria that fix nitrogen. These bacteria live in nodules on the roots of legumes and use a process called nitrogen fixation to convert atmospheric nitrogen into a form that plants can use.
Legumes can obtain substantial amounts of nitrogen, an important nutrient for plant growth, without being entirely dependent on soil nitrogen, because of their ability to fix nitrogen. Legumes play an important role in agriculture and ecosystems, by adding nitrogen to the soil and increasing its fertility. Legumes are valuable crops because of their high protein content as well as their ability to improve soil health by fixing nitrogen.
Therefore, the correct option is A.

What do individuals who are heterozygous for codominant traits show for a
phenotype?
Answer:
Individuals who are heterozygous for co-dominant traits show in their phenotype both traits, without mixing.
Explanation:
Codominance is a type of inheritance that does not follow the rules of Mendelian inheritance, characterized by the absence of recessive traits and two different alleles for a character that behave as dominant.
Heterozygous individuals can be observed in codominance that show two different characteristics in their phenotype, without mixing, such as cattle with spotted skin or two colored flowers.

When ATP levels fall ________ binds to ________of ____________. This interaction leads to an increase of cellular ___________ , so that this is a n example of a ___________ feedback loop.
Answer:
Explanation:
The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.
An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.
This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.
What is an enzyme?An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.
Factors that affects an enzymeThere are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.
