Answer:
It it not, In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.

why is endosymbiotic theory not a law in science?
Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.
Explanation:
Deoxyribonucleic acid and ribonucleic acid (DNA and RNA, respectively) are very important
biomolecules necessary for life. In at least 7 sentences and in your own words, compare
and contrast DNA and RNA. Explain what you know about the components (parts) of DNA
and RNA and their importance. Be sure to include at least five of the following words:
.
• Nucleic acid
• Nucleotide
• Nitrogen base
• Gene
• Genetic code
• Phosphate
• Sugar
• Protein
• Double helix
• Backbone
Answer:
pa heart follow back follow me brainliest me please
Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
Each nucleotide triplet (or 3 bases at a time) in mRNA that specifies a particular
amino acid is called a.....

The sun is shining at a church with a stained glass window. What happens?
Answer:
c
Explanation:
because if it's stained then the sun does pass through it as well
Answer:
c

because light is all colors in one form, white, (i think) only some of the light can pass through. some colors going through certian colors, others blocking or absorbing the light
im like 90% sure that thats right, although i do know the answer is c
HELP!! is the digestion of glucose active or passive transport
Answer:
However, there will be times when glucose concentration in the intestine might be lower. When this is the case, movement of glucose involves active transport. The process requires energy produced by respiration .

why is there is no point in adding more generations when an allele has become fixed
Answer:
Low genetic diversity, which is seen with allele fixation, is dangerous as it can lead to mass extinctions. If there is little genetic variability within a population and the genetically similar individuals all are susceptible to a certain pathogen, the population will likely cease to exist. This is why we see examples of populations with fixed alleles becoming threatened or endangered
Explanation:
basically, it will cause extinction

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea
Answer: He performed dihybrid crosses
Explanation:
Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.
Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.
which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.

Individuals in a species have genetic variation that can be passed on to their offspring
Answer: Genetic variation within a species can result from a few different sources. Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. ... As a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes.
