Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.

Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.
Answer:
cannot grow outside their host cell of biolapsy
The symbiotic relationship is a type of relationship in which two organisms living with each other and gives benefit to one another.
Mutualism is a type of symbiotic relationship in which both organisms benefited from one another. In this type of relationship, one organisms is smaller that lives inside the body of other big organisms.
For example, bacteria lives in the nodules of plant's root. The plant provides shelter to the bacteria while on the other hand, bacteria fixes atmosphere nitrogen into available form so in this way both get benefits from one another.

What are the DNA base pairs?
Need asap
Answer:
I hope i helped
Explanation:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins can recognize specific base-pairing patterns that identify particular regulatory regions of genes.

Explanation:
how lond does it take harry to go 0.7 miles if he can run 12 miles in 6 minutes
Answer:
Harry will take 21 seconds.
Explanation:
Speed of Harry = [tex]\frac{\text{Distance covered}}{\text{Time taken}}[/tex]
Since, Harry covers 12 miles in 6 minutes,
Then the speed of Harry = [tex]\frac{12}{6}[/tex]
= 2 miles per minute
If he covers 0.7 miles then time taken by him will be,
Time taken = [tex]\frac{\text{Distance covered}}{\text{Speed}}[/tex]
= [tex]\frac{0.7}{2}[/tex]
= 0.35 minutes
≈ 0.35 × 60 seconds
= 21 seconds

Where would a frameshift mutation cause the most damage?
Near the very end of the gene
Near the beginning of the gene
Near the center of the gene
All frameshift mutations are equal
Answer:
All frameshift mutations are equal
Explanation:
Frameshift mutation is a type of mutation caused by insertion or deletion of nucleotide base(s) in a genetic sequence causing that sequence to be read in a different way from what was originally planned.
The bases in the sequence of a gene is read in three's (codon), however, when one or more bases is added (insertion) or removed (deleted), the reading frame is altered causing the sequence to be read in a completely different order that can result in a protein that is non-functional.
However, FRAMESHIFT MUTATION is so potent that it affects the sequence no matter where it occurs. In other words, the effect of all frameshift mutations are equal.

what is digestion? Starting from mouth, state the various steps involved in digestion
Answer:
The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.
Explanation:
The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.
A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.
In any given population, certain individuals are more able than others to adjust to environmental changes. Some of these changes are temperature, food supply, pollution, and

A farmer grows several crops on a farm that has mostly shallow, sandy soil, meaning they have
a low water storage capacity and a high infiltration rate. Which of the following irrigation
methods would be the best suited for this farm?
Select one:
O a. Drip irrigation
O b. Surface irrigation
O c. Flood irrigation
O d. Furrow irrigation
For a sandy soil farmer should use drip irrigation method over surface irrigation.
Sandy soils have a low water storage capacity and a high infiltration rate. Therefore they need frequent but small irrigation methods, drip irrigation is most suitable method than surface irrigation.
In other irrigation methods such as Surface irrigation, Flood irrigation, Furrow irrigation water is discharged in quite large amounts but the soil lost it due to the high infiltration rate.
Therefore, for a sandy soil farmer should use drip irrigation method over surface irrigation.

What does it mean for a trait to be dominant?
A.That it will be hidden by the recessive trait and not show up in the offspring.
B.That it will be the allele that will be shown in the offspring.
Answer:
B
Explanation:
Answer:
B. That it will be the allele that will be shown in the offspring
Explanation:
If something is dominant, that means it's stronger or more assertive. Think of an alpha wolf. It is dominant and is more assertive over its pack. The same is true for alleles (in most cases)

Gene:A gene is the basic physical and functional unit of heredity.Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases.Every person has two copies of each gene, one inherited from each parent.Thus, option 4 is correct.
