Answer:
Mechanical
94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.
Chemical
school bus uses petroleum as chemical potential energy.
Electrical
An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again
Thermal
They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.
A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?
Answer:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
Explanation:
This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.
OR if the baby sheep received a mixed set of genes , one from father , the other from mother , the gene of the father is dominant over the gene of the mother and it has given the baby sheep curly wool.
During fertilization the baby must have received the same set of genes as those of its father. If the baby has received a mixed set of genes then the genes of the father are dominant over the genes of the mother resulting in curly wool.
The fathers gene may be dominant due to environmental circumstances or other factors.
Answer:
Explanation:The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.

Why do multicellular organisms perform mitosis and meiosis ?
Answer:
Multicellular organisms depend on mitosis for growth and repair. When an animal, plant or other multicellular organism grows, it makes more cells through mitosis. Organisms can repair some of their tissues, using mitosis to regenerate new cells.
Explanation:
Consider the four organisms you see here. Each represents a specific kingdom. They all exhibit the characteristics of life. Think about
their life cycles. Compare and contrast the life cycles of the four. How do they differ?

Three common methods employed in the cleanup of oil spills are aeration of water, skimmer boats, and genetically engineered bacteria aeration of water, skimmer boats, and genetically engineered bacteria A aeration of water, phytoremediation, and genetically engineered bacteria aeration of water, phytoremediation, and genetically engineered bacteria B skimmer boats, high temperature incineration, and phytoremediation skimmer boats, high temperature incineration, and phytoremediation C large floating booms, high temperature incineration, and phytoremediation large floating booms, high temperature incineration, and phytoremediation D large floating booms, skimmer boats, and genetically engineered bacteria
Answer:
large floating booms, skimmer boats, and genetically engineered bacteria
Explanation:
Skimmers are used in the clean up of oil spills it makes use of containment skims that act like a fence and the surface of water and prevent the oil spill from moving or spreading across the water surface. It contains the oil into a particular place. Floating booms helps in the sucking out of oil in the confined area, its act like a vacuum pump and suck out all the oil spills available in the areas confined by the skimmers.
Bioremediation involves the use of microorganisms to clean up spills this micro organism breaks down this petroleum product into harmless substance through their metabolic activities. Genetically modified Bacterial can be use for this purpose to help break down this hydrocarbons and make them less toxic.
A man and a woman have a child together. The mother's blood type is type O and the child's blood type is type A What could the father's genotype be?
Answer:
iAiA or iAi = Type A
Explanation:
Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".

What are some ways you think scientists can affect or utilize the genes of organisms?
Answer:
I'm not quite sure what your looking for
Explanation: scientists can take the genes of one successful crop, animal, etc, and insert that gene into future things so all offspring will be successful. This is called genetically modifying. Another thing scientists can utilize genes for is cloning. There have been ideals of the perfect human for many years and now scientists are trying to alter these genes to have perfect offspring according to your standards.

How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars
Answer:
b
Explanation:
Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.
The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.
Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:
DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formationThus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.
