Answer:
a. Five-Carbon Sugar and Phosphate
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.

what is kerbs cycle and where it occur?
Answer:
Explanation:
The Krebs cycle is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidization of acetate—derived from carbohydrates, fats, and proteins —into carbon dioxide.
OR,
It is a biochemical process by which nutrients are broken down to release energy, which gets stored in the form of ATP and waste products are released.
The Krebs cycle occurs only within the mitochondrial matrix.
If you found my answer useful then please mark me brainliest.
Answer:
The Krebs cycle or Citric acid cycle is a series of enzyme catalysed reactions occurring in the mitochondrial matrix, where acetyl-CoA is oxidised to form carbon dioxide and coenzymes are reduced, which generate ATP in the electron transport chain. Krebs cycle was named after Hans Krebs, who postulated the detailed cycle.
Explanation:
13. With the massive amount of plant life, ample rainfall and favorable temperatures, you might think
that tropical rainforests would be large net producers of oxygen, and yet surprisingly, they are not! With
your knowledge of photosynthesis and cellular respiration, can you explain why this might be true?
Think about what happens when a leaf drops or fruit from a tree is eaten.
Answer:
Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.
Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.
After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.
Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.
2. Many people believe that a mutation will always result in the formation of a deadly tumor, or the development of a major body defect.
Explain why this is incorrect.
. There are multiple types of mutations in DNA. ______________mutations occur when a single base is changed to a different base pair.______________mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation. __________mutations are also considered frameshift mutations, and occur when one or more extra bases are added to a segment of DNA.
Answer:
substitution; deletion; insertion
Explanation:
Mutations are genetic changes generally associated with deleterious effects. However, mutations may not have an effect on the phenotype of the organism and even, eventually, they are beneficial. For example, a missense substitution occurs when a nucleotide is replaced by another that changes the encoded amino acid, which may have deleterious or beneficial effects (depending on the new protein and its effects on the fitness of the individual in a particular environment), while a silent substitution does not modify the encoded amino acid and thereby it has no effect on the phenotype. On the other hand, a frameshift mutation is a mutation that involves the insertion or deletion of a nucleotide base, thereby irreversibly altering the Open Reading Frame (ORF) of the protein.

Which of the following statements are true about hydrogen bonds? (More than one)
A.) A hydrogen bond is stronger than a covelent bond.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on
another water molecule is an example,
D.) A hydrogen bond is stronger than an ionice bond.
Answer:B,C
Explanation: covalent and ionic bonds hold molecules together. It is the polarity of covalent bonds that give rise to hydrogen bonding. As in the water example: the more electronegative O attracts electrons slightly more than the hydrogens, so the O has a fractional negative charge, the Hs a slight positive charge. The O of one molecule and the H of another are held together by this charge difference.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on another water molecule is an example,
Hydrogen bonds exists between molecules in which hydrogen is bonded to a high electronegative atom such as nitrogen, chlorine, fluorine, sulphur etc.
Hydrogen bonds are strong intermolecular interactions. They are responsible for the high boiling and melting points of some polar substances such as water.
However, hydrogen bonds are not as strong as covalent or ionic bonds.

One result of meiosis is the formation of gametes
A. True
B. False
Answer:
T
Explanation:
It is true that the result of meiosis is the formation of gametes. Therefore, option A is correct.
What is meiosis?a unique method of cell division in which the amount of DNA received by each daughter cell is halved compared to the parent cell. In mammals, meiosis takes place during the development of egg and sperm cells.
Since meiosis involves two rounds of cell division, a beginning cell can generate four gametes (eggs or sperm). Cells move through prophase, metaphase, anaphase, and telophase with each round of division.
Chromosome reduction, or meiosis, is the process that enables the generation of haploid germ cells required for sexual reproduction. Meiosis also plays a crucial function in promoting genetic variety and making it easier for recombination to correct genetic flaws. Hence, option A is correct.

What features of larkeys affect their survival?
What traits helped larkeys survive when they moved to the prairie environment?
What traits helped larkeys survive when they moved to the forest environments?
What factors in the environment affected the survival of larkeys?
Answer:
el sapo
Explanation:
Spotted larkeys were difficult for bobcats to see in the forest because they mixed in with the dappled light coming through the trees. Larkeys with short legs might hide from the bobcats by ducking behind shrubs. Bobcats could easily notice striped larkey in the dense jungle.
What are the features of larkeys to affect their survival?Striped larkeys were tougher for the coyotes to locate in the prairie because they mixed in with the prairie grass.
The ability to sprint quicker gave long-legged larkeys a better chance of eluding the coyotes. However, because of the surrounding grass, spotted larkeys were simple for the coyotes to spot.
Therefore, The prairie larkey's short legs and spots and the forest larkey's long legs and stripes both failed to help them withstand the pressure.

Diffusion of nutrients across a cell membrane can be called a form of Multiple Choice bulk transport. exocytosis. osmosis. active transport. passive transport.
Answer:
passive transport
Explanation:
Diffusion is one of the ways molecules/substances move or is transported. It is the process whereby substances move from a region of higher concentration to a region of lower concentration until there is an even distribution. Movement via diffusion occurs down a concentration gradient i.e high to low.
Since diffusion occurs down a concentration gradient, which is difference in concentration of a substance, it requires no energy in form of ATP to occur. This kind of transport which requires no energy input is called PASSIVE TRANSPORT, in contrast to active transport which requires.

a glass marble has a volume of 5 cm3 and a mass of 13 g. what is the density of the marble
Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
The density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.
What is Density?Density may be defined as a type of physical quantity that measures the degree of compactness of a substance. It may also be characterized as the substance's mass per unit of volume. The symbol most often used for density is ρ (row).
According to the context of this question,
The mass of a glass marble = 13 g.
The volume of a glass marble = 5 cm3.
The formula for calculating density is as follows:
Density = Mass/volume.Density = 13 g/5 cm3 = 2.6 g/cm3.
