which kind of cells carry out the process of cellular respiration?
All living cells must carry out cellular respiration. It can be aerobic or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells, while Mitochondria carry out the cellular respiration in eukaryotic cells. They are also called as the 'Power house' of the cell as they produce the energy needed to the cell to function properly.
what must happen before miosis can begin?
Answer:
Before meiosis actually begins, the DNA that is packaged into chromosomes must be fully copied. ... DNA replication occurs in the same fashion as it does during mitosis. After replication, the homologues are doubled, and each chromosome now has a homologous pair
If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Answer: 4 Guanines
Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.
We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
The DNA is a double-stranded molecule, which is made up of purine, pyrimidine, a pentose sugar, and phosphate backbone. Chargaff's rule states that any species will have a stoichiometric ratio of 1:1.
The number of guanines in the double-stranded DNA is 4.
In the DNA, the base pairing occurs as:
The guanines bind with cytosine through hydrogen bonding. The adenine binds with thymine with two hydrogen bonds.In the given nucleotide, there are 23 purines (guanine and adenine). There are 15 thymines in the DNA molecule. Based on the Chargaff rule, the 15 thymines will bind to adenine, leaving only 4 guanines and 4 cytosines. Thus, there will be 4 cytosines left to bond with the guanines to achieve Chargaff's ratio of 1:1.
Therefore, the guanine in the nucleotides will be 4.

Which of the following base pairs would be found in a cell
The base pair cytosine and guanine is found in the cell. The correct option is D.
What are base pairs?A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.
They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.
Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.
Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.
The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.
Thus, the correct option is D.

suggest two factors other than the rate of nitrogen fixation that may affect the avality of nitrogen in the marine ecosystem
Answer: run off from land/rivers and phytoplankton blooms
Explanation:
Nitrogen, particularly as nitrate is easily leached from soil. Human agriculture relies on fertilisers with significant nitrate content that applied at levels higher than it can be used. The balance end up as runoff, much of which ends up in
The two factors that are other than the rate of nitrogen fixation that fit the marine ecosystem are runoff from the land or rivers and the phytoplankton blooms
Waht is nitrogen fixation ?Nitrogen fixation refers to the chemical process by which molecule N2 has a strong Tripple covalent bond and in the air, it gets coveted into NH3 or a related nitrogenous compound that is typically in soil or aquatic system.
The fixation is essential for life as inorganic nitrogen compounds are needed for the biosynthesis of nitgen-containing organic compounds like amino acids.
As nitrogen is easily found in soil and can be added by fertilizers it ends as runoff and damages the ecosystem.

What is the reason for the increased number of drug resistant bacteria being found in hospitals?

A. An artesian well needs the pressure of a confined aquifer
B. An artesian well must be near a lake
C. An artesian well must be near the site of groundwater infiltration
D. An artesian well only works in areas that are going through a drought
Answer:
it is a
Explanation:
i did the test
A farmer has decided to dig an artesian well into the unconfined aquifer below his crops. His well is not working because an artesian well needs the pressure of a confined aquifer. The correct option is A.
What is an aquifer?An artesian well is a deep tube well drilled underground to gather water for human usage. This good type is found in restricted aquifers.
The artesian well differs from the others in that it does not require the use of a pump to raise the water, as the cistern does. The sort of subsurface reservoir causes the water that travels through the tube to naturally spurt to the surface.
The underground reservoir with the qualities required for drilling an artesian well is the product of extremely specialized geological conditions. Gushing wells are caused by the restricted aquifer, as this sort of deep groundwater is known. This type of reservoir is found between impermeable subsurface layers.
Therefore, the correct option is A. An artesian well needs the pressure of a confined aquifer.

Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Asexual reproduction produces offspring genetically different from parents.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Sexual reproduction produces organisms that are genetically diverse.
Answer:D
Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.
Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.
Sexual reproduction produces organisms that are genetically diverse.
Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.
Hence, the statement that correctly states why one type of reproduction is beneficial over the other is that sexual reproduction produces organisms that are genetically diverse.
