If a DNA molecule with a total of 2500 nucleotides has 1500 purines, how many guanines are in this DNA molecule?
Answer:
I'm pretty sure there would be 1000 guanines in the DNA molecule.
Explanation:
Hope this helps. . . <3
If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.
What will be the total number of thymines if a DNA molecule has a total of 1500nucleotides?The DNA molecules would be given and it have 450 thymines if the DNA molecule has the total of 1500 nucleotides and the DNA molecule also have been known as the deoxyribonucleic acid has been made up of the double helix. The DNA molecule with the total of 1500 nucleotides would contain 750 cytosine and Thymines and 750 guanines and adenine.
Hence, we can have the expression:
C + T = 750
If there are 300 cytosines, hence;
300 + T = 750
T = 750 - 300
T = 450
A nucleotide has the monomer constituting DNA or RNA biopolymer molecules and the double-stranded DNA molecule posseses two strands of DNA made up of the nucleotides.
Therefore, If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.
Answer:
see below
Explanation:
Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.
Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.
Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.
So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.
The relationship between predator and prey species is modeled here with the owls and rodents. Which statement(s) correctly evaluate
the relationship between these species with regards to evolution? Select ALL that apply.
es )
A)
The presence of the owls is a selective pressure for the rodents.
B)
Fewer rodents result in an overpopulation of owls, leading to their
evolution
o
Coevolution is occurring as each population is evolving in response to the
other.
D)
Owls that see camouflaged rodents are more likely to evolve to have
increased variation
E)
Coloration results in poorly or well-adapted rodents while eyesight level
can lead to poor or well-adapted owls.
Answer:A, C, E .
Explanation:

A) The presence of the owls is a selective pressure for the rodents.
C) Coevolution is occurring as each population is evolving in response to the other.
What is predator?A predator is an organism that hunts, kills, and feeds on another organism known as the prey. Predation is a biological interaction between two species, where one species benefits by consuming the other species, and the other species is harmed or killed.
These two statements correctly evaluate the relationship between the predator and prey species in terms of evolution. The presence of owls as predators creates a selective pressure for rodents, where those with traits that allow them to escape predation are more likely to survive and pass on their genes.
This leads to the evolution of better-adapted traits in the rodent population over time. The interaction between owls and rodents can also be considered an example of coevolution, as changes in one population can drive changes in the other population, leading to a reciprocal evolutionary response.
Overall, the relationship between predator and prey species is complex and constantly evolving, with each population influencing the other's evolution over time.

Which of the following is not
one of the kingdoms of living
things?
a Fungi
b. Bacteria
c. Animalia
d. Protista
Answer:
B. Bacteria
Explanation:
Because bacteria are unicellular organisms belonging to the prokaryotic group where the organisms lack a few organelles and a true nucleus
Bacteria is not one of the kingdoms of living things. So, the correct option is (B).
What are the Different kingdoms of Living things?Living things are divided into 5 kingdoms. These are:
1. Monera
It is the kingdom of microscopic living things that groups together prokaryotes (archaea and bacteria) present in all habitats and composed of single-celled things without a defined nucleus. Bacteria belongs to this kingdom.
2. Protista
This group is primitive of eukaryotic which is paraphyletic which includes common ancestor but not all its descendants. Protozoa belongs to this kingdom.
3. Fungi
This kingdom includes yeasts, molds and all species of mushrooms and toadstools, which are multicellular aerobic heterotrophic eukaryotes, have chitin in their cell walls, feed on other living things, and reproduce by means of spores.
4. Plantae
Trees, plants belong to the kingdom Plantae, which is characterized by its sedentary, multicellular and eukaryotic nature. They are autotrophs, whose cells contain cellulose and chlorophyll which are essential for life on Earth as they release oxygen through photosynthesis.
5. Animalia
The kingdom Animalia is divided into two major groups – vertebrates and invertebrates which are multi-celled, heterotrophic eukaryotes that have aerobic respiration, sexual reproduction and the ability to move. This kingdom includes mammals, fish, birds, reptiles, amphibians, insects, molluscs and annelids.
Thus, Bacteria is not one of the kingdoms of living things. So, the correct option is (B).

4) reconstructive; we should wonder about the accuracy of people's memories
5) reconstructive; we should be confident about the accuracy of people's memories
Memory is reconstructive and we should therefore wonder about the accuracy of people's memories.
Recalling an event via memory has the tendency to be influenced by other cognitive processes, including perception, beliefs, ideologies, imaginations, etc. This phenomenon, known as reconstructive memory, is one of the key theories of memory recall.
This is one of the reasons 2 people who witnessed an event will have different reports for the same event. Thus, the reconstructive memory theory leaves no other option but to wonder about the accuracy of people's memories.

Recombination (crossing over) during prophase I of meiosis occurs when:
Answer:
meiosis before tetrads are aligned along the equator in metaphase I.
Explanation:
When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I
