Which material heats fastest, the rock, the sand or the water?
Explain your answer.
Answers
Answer:
Sand
Explanation:
Sand heated up faster than water because sand is darker than water; dark-colored materials will absorb more light. Sand heated up faster than water because sand is a solid and water is a liquid. Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.

Some cells release active signaling proteins when membrane-bound precursor proteins are cleaved by proteolytic enzymes. The signaling proteins can then bind to receptors on the surface of a target cell, thereby activating an intracellular signaling pathway and eliciting a response from the target cell. This mechanism of activating receptor-binding signaling proteins has been observed in a variety of organisms from bacteria to humans. Many of the enzymes responsible for proteolysis of membrane-bound precursor proteins have been isolated and characterized.
Required:
What questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species?
Answers
Answer:
Following questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species:
Are the genes encoding the proteolytic enzymes expressed in the same cell types in all species? Once the precursor proteins of different species are cleaved, do the active signaling proteins bind to the same receptors on different target cells? If a proteolytic enzyme from one species is incubated with a precursor protein from another species, does correct cleavage occur? Are the proteolytic enzymes synthesized in the rough endoplasmic reticulum of all species?
6. How might protein synthesis execute differently if a mutation occurs?
Answers
Answer:

Explanation:
The mutated DNA is taken through the whole protein synthesis process and translated by the rRNA and tRNA to create a protein from that new sequence.
Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: rejection of the transplanted organ would not be expected. antibodies would be generated against the transplanted organ. antigens would be generated against the transplanted organ. immunosuppressant drugs would be required to prevent transplant rejection. rejection of the transplanted organ would still be expected.
Answers
Answer:
rejection of the transplanted organ would not be expected.
Explanation:
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
In the field of Medicine and Surgery, an organ is sometimes replaced for specific reasons, by moving it from one part of the body to another; this process is generally referred to as a transplant. Thus, it's mainly done to replace damaged skin or joints in the body of a living organism such as humans.
Hence, in these cases, rejection of the transplanted organ would not be expected because an examination and matching of the organ is carried out by the medical professionals before transplant.
On your Spring Break in Mexico, you take a break to count the starfish in a tidal pool. You notice that there is a rare recessive trait that causes the starfish to have 6 legs instead of 5. Of the 27 starfish you can find, only 1 has 6 legs. What are the allele frequencies for this population
Answers
Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.
Trace minerals are needed in much smaller amounts than major minerals, but they are just as essential for good health.
a. True
b. False
Answers
Answer:
The correct answer is - true.
Explanation:
Like macromolecules and vitamins, minerals are also essential for a healthy body. The essential minerals can be divided on the basis of their requirement into major minerals and trace minerals.
The trace elements and the major elements both are equally important. It does not matter if a high amount of major elements are required and a small amount of trace elements required. The amount is not an indication of the importance of the element.

A homeowner lives adjacent to some wetlands, which contain standing water for much of the year. During the summer months, the
mosquitoes in the area are excessive and pose a nuisance to the homeowner. The homeowner decides to spray an insecticide on
the lawn and adjacent wetlands to eradicate the mosquitoes. The homeowner notices that after the application of the insecticide,
the number of mosquitoes is significantly reduced.
The following year, the number of mosquitoes increases in frequency as the summer months arrive and the temperatures get
warmer. The homeowner once again applies the same insecticide to the yard and adjacent wetland areas. However, this time, the
homeowner does not notice a reduction in the mosquito population after applying the chemical.
Evaluate the scenario above and select ALL statement below that apply to this case study.
A)
B)
The insecticide no longer has a chemical that can kill any mosquitoes after
the first year.
The application of the insecticide caused directional selection in the
mosquito population
There were some mosquitoes with innate genetic resistance to the
insecticide before it was sprayed the first time.
C)
D)
Natural selection selects for a phenotype in a population that has an
advantage under certain environmental pressure.
E)

which made them resistance to the chemical.
Answers
Answer: B, C, and D
Explanation:
The application of the insecticide caused directional selection in the mosquito population. There were some mosquitoes with innate genetic resistance to the insecticide before it was sprayed the first time. Natural selection selects for a phenotype in a population that has an advantage under certain environmental pressure. The correct options are B, C, and D.

What would cause a person to have two copies of the bent thumb allele (tt)?
1. A person whose mother or father had two copies of the bent thumb allele will always have two copies of the allele.
2.A person with two copies of "t" inherited one from their mother and one from their father.
3. A person born with one "t" mutation is more likely to develop a second "t" mutation during their lifetime.
4. A person with two copies must have duplicated the "t" allele through mitosis early in development. (They inherited one, then doubled it)
Answers
Answer:
A person with two copies of "t" inherited one from their mother and one from their father
Explanation:
This is because both the father and the mother are carriers of "t" alleles which is a bent thumb. When the parent mate, the father donate one t and the mother too donate one t allele, therefore the person will inherit bent thumb from them.
