Explanation:
DNA replication is a process that involves copying the DNA molecule if a single base was miscopied what would be a possible result of this for the cell in which it happened
Answer:
If a single base is miscopied during replication then there is a possibility that the new base which has been incorporated will specify the same amino acid just like the old base. It happens because genetic code is degenerate which means that more than one codon can specify same amino acid.

I think it would create two identiacle daughter cell soory for my spelling

PLS HELP ME pls SO IT SAYS READ the text and say how the adaption is occured in hummingburs and how they were savory flavors but now they are sweet sensing now how it got adapted make a cer How did the presence of an adaptation change the frequency of a specific trait in hummingbirds? This will be graded based on your overall claim and supporting statements, use of evide from the text, and your encreasoning (CER).
Most humans enjoy candy, cake, and ice cream. As a result of evolutionary history, we have a wide variety of tastes. This is not true of all animals. Cats do not seek sweets. Over the course of their evolutionary history, the cat family tree lost a gene to detect sweet flavors. Most birds also lack this gene, with a few exceptions. Hummingbirds are sugar junkies.
Hummingbirds evolved from an insect-eating ancestor. The genes that detect the savory flavor of insects underwent changes, making hummingbirds more sensitive to sugars. These new sweet-sensing genes give hummingbirds a preference for high-calorie flower nectar. Hummingbirds actually reject certain flowers whose nectar is not sweet enough!

What is ABO system in blood group?In humans, the blood group system is known as the ABO system where blood groups A and B are codominant and O blood group is recessive. The genotype of the A blood group could be AA or AO similarly for the B blood group genotype would be BB or BO, for the O blood group OO whereas for the AB blood group both A and B alleles should be present together.

Answer:
The answer is double helix.
Explanation:
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.

Type a summary of the phases of water and how a substance changes from one to the other.
Answer:
There are three phases of water that include solid water, liquid water and gas water. Water in solid phase has definite shape and size and molecules are closely packed for example: ice, water in liquid phase or liquid water phase, molecules are close together but can move as per the shape of container, for example: juice; and gas water phase is the phase in which molecules are far from each other.
Same as matter, the phases of water also changes as per the temperature and pressure of the ecosystem changes. When temperature increases, Solid water changes to liquid water and the process called melting and liquid water convert into gas water and the process called vaporization. When temperature decreases, liquid water convert into solid water with the process freezing and gas water convert into liquid water through condensation.

Which term refers to two species in the same area using the same resources,
such as bison and prairie dogs?
O A. Nutrient availability
B. Interspecific competition
C. Invasive species
D. Territoriality
Interspecific competition refers to two species in the same area using the same resources, such as bison and prairie dogs.
What is interspecific competition?Interspecific competition is a form of competition between organisms of different species that occupy similar ecological niches and compete for the same limited resources such as food, water, space, and mates. These resources are essential for the survival and reproduction of the competing species, and their scarcity can lead to negative impacts on the growth, reproduction, and survival of one or both species.
Interspecific competition can result in the exclusion of one species from an area, the evolution of unique adaptations that allow a species to exploit a different resource, or a stable coexistence of both species through resource partitioning. Interspecific competition is an important ecological force that shapes the diversity and distribution of species in an ecosystem.

How does force affect acceleration?
Answer:
The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

What part of the atom allows one atom to react with another one
Answer: An important principle to know is electrons may be transferred from one atom to another or even shared between atoms (allowing atoms to bind together). These bonds allow for the formation of molecules, combinations of atoms (including those of different elements).Explanation:
DNA replication requires all of the following EXCEPT: a template, that is, a strand or strands to be copied. the monomers that are assembled into the new strand, including dCTP. the enzymes that carry out the process, including primase. the enzymes that carry out the process, including topoisomerase. Actually, all of these are required for DNA replication.
Answer:
Actually, all of these are required for DNA replication.
Explanation:
This is because DNA replication is the process where double stranded DNA are copied and produced from the parent DNA molecule. For DNA replication to occur there must be a strand of DNA that must be copied, the monomers from the parent molecule, the enzymes that carry out replication process, primase and topoisomerase.

Why is boron less chemically reactive than beryllium?
A. Boron needs to lose 3 electrons to have a full outer shell, while
beryllium needs to gain 2.
B. Boron needs to lose 3 electrons to have a full outer shell, while
beryllium needs to lose only 2.
C. Boron needs to gain 3 electrons to have a full outer shell, while
beryllium needs to lose 2.
D. Boron needs to gain 3 electrons to have a full outer shell, while
beryllium needs to gain only 2.
Answer:b
Explanation:
Boron is less chemically reactive than beryllium because boron needs to lose 3 electrons to have a full outer shell, while beryllium needs to lose only 2. Thus, the correct option is B.
What are electrons?Electrons may be characterized as the types of subatomic particles that are present within the atoms along with protons and neutrons. Electrons are negatively charged in nature and always revolve around the nucleus of the atom. They were discovered by J. J. Thomson.
The atomic number of boron is 5 which means there are three electrons in its valence shell and in order to obtain stability, boron either require 5 electrons to gain or three electrons to lose. Three electrons to lose is comparatively easy. The same principle is applied to beryllium which has an atomic number of 4.
Therefore, Boron is less chemically reactive than beryllium because boron needs to lose 3 electrons to have a full outer shell, while beryllium needs to lose only 2. Thus, the correct option is B.
