Answer:
only one codon; a single amino acid change
Explanation:
The genetic code is a set of nearly universal rules by which living cells direct the translation of the information encoded in genetic material (either DNA or RNA) into amino acids. The messenger RNA (mRNA) sequence obtained from the process of transcription consists of triplets of nucleotides or 'codons' which are used to code for all the 20 essential amino acids during translation. The genetic code is not overlapping because each letter contained in the genetic material (i.e., each nucleotide) cannot be used for two different codons. In consequence, a single substitution (mutation) in the nucleotide sequence can change only one codon, thereby changing only one amino acid in the polypeptide chain.

Why do organisms need both mitosis and meiosis to process?
Explanation:
Both mitosis and meiosis processes are extremely important because they are the division of chromosomes and without this division reproduction would not occur. Cell division plays an important role in the life cycle of a cell allowing the cell to grow, develop and then reproduce.
Mitosis and meiosis are cell divisions that are needed by organisms because of its importance to them.
Mitosis is a type of cell division where by a single cell divides to form two identical daughter cells.
The importance of mitosis to organisms include:
They help in repairing the damaged cells,They help in growth and development of organisms.Meiosis is a type of cell division where by a single cell divides two times to produce four cells.
These four cells contain half the original amount of genetic information of the divided cell.
The importance of meiosis to organisms include:
It ensures the possibility of sexual reproduction in organismsIt leads to production of genetic variation in organisms.Therefore due to the importance of meiosis and mitosis listed above, they are needs to organisms.

of differences in their DNA and protein
sequences?
a. Radish and seaweed
b. Banana and lemon
c. Onion and radish
d. Banana and onion
Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.
What is DNA?
DNA contains the genetic information needed to determine the structure and function of living organisms. Each DNA molecule is found on a chromosome, and the segments of that DNA molecule are genes.
In somatic cells -such as nerve and muscle cells- the DNA sequences are the same, but what determines the synthesis of different proteins is the information that the genes have, i.e., fragments of DNA contained in a cell.
For this reason, nerve cells have a gene that allows them to synthesize the enzyme cholinesterase, while muscle cells have a gene that codes for myosin, even though they both possess the same DNA sequence.
Therefore, Based on the model, Banana and lemon are the pairs of species most likely have the greatest number of differences in their DNA and protein sequences. Thus, option B is correct.

Answer glatus m.
Explanation:
Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
Which pattern of inheritance would explain the different fur color in the related dogs?
Polygenic inheritance is simply a form of inheritance whereby the trait of the individual or the animal is gotten from the cumulative effects of several genes. In such case, there are many genes which control the expression of the trait. This is quite different from the monogenic inheritance whereby the trait is as a result of the expression of just only one gene.
Since Pietro has two dogs that are related, and one of the dogs has tan fur and the other has brown fur, then this means there's more than one gene which is expressed in this case.
In conclusion, the answer to the question is polygenic inheritance.

what is photosynthesis
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Bauxite is an ore that is mined extensively. What makes bauxite a valuable ore?
A It is extracted for use in food.
B It is burned to generate electricity in power plants.
C It is the primary source for aluminum.
D It is used in the production of steel.
Answer:
C
Explanation:
Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite. In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus various mixtures of silica, iron oxide, titania, and other impurities in trace amounts. The principal aluminum hydroxide minerals found in varying proportions within bauxite are gibbsite (trihydrated) and boehmite and diaspore (both monohydrated). The content of aluminum oxide is 30–60%. Bauxite is generally extracted by open cast mining from strata, typically 4–6 m thick under a shallow covering of topsoil and vegetation (Table I).

This fossil bird and this living salamander both have tails. However, they have different tail structures. The bird has a very short tail made of just one bone that helps it have a light skeleton for flying. The salamander has a long tail with many bones that helps it balance while it runs. What most likely explains why both the bird and salamander have tails and why the tails are different
The fossil bird and salamander both have different tail structure because they both inherited tails from a shared ancestor population initially, but this population eventually separated into different environments.
In order to adapt into their immediate environment they both evolve their tail structure to carry out different functions.How does evolution occur? It is the change in the phenotypic characters of a species over several generation resulting from natural selection and genetic drift.The the tail of salamander was evolved to store fat and proteins, assistance in the movement, hence it has long tail with many bones for ease of movement.
Whereas birds short and light weight tail for the ease of flying and normal functioning.
Hence, different body structure evolved from the same ancestors for the adaptation in different species.
