Answer:
decomposers
Explanation:
These are heterotrophic organisms that feed on dead animals and plants, secretions, or discarded parts of living beings, that is, organic matter.
And they break it down into inorganic.
Thus, inorganic substances that can be reused in the process of photosynthesis are returned, recycled, to nature.

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 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.

Why does the body produce carbon dioxide if it is harmful to the human
body?
Answer:
Carbon monoxide can kill. The gas forms when there is not enough oxygen to produce carbon dioxide -- essentially when the carbon in fuel is not burned completely. Carbon monoxide prevents oxygen in the blood from being carried throughout the body, causing asphyxiation.

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.

What is a ribososme?Ribosomes, also called Palad granules (after their discoverer George Palade, for their granular structure), are macromolecular machinery found in all cells that perform biological protein synthesis (mRNA translation).Ribosomes join amino acids in an order determined by the codons of the messenger RNA (mRNA) molecule to form a polypeptide chain. Ribosomes are composed of two major components, the large and small ribosomal subunits.Each subunit is composed of one or more ribosomal RNA (rRNA) molecules and many ribosomal proteins (RPs or r-proteins).Ribosomes and related molecules are also known as the translational apparatus.The ribosome is a ribonucleoprotein complex because it is composed of a complex of RNA and protein.Each ribosome is composed of smaller (30S) and larger (50S) building blocks called subunits.

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.
