Which diagram correctly shows how heterozygous alleles are found on homologous chromosomes?
Answers
Answer:
The answer is I think D
Explanation:
The diagram that correctly shows how heterozygous alleles are found on homologous chromosomes is ; Aa ( The first diagram )
Heterozygous alleles are different alleles gotten/inherited from the genes inherited from each parent cells ( i.e. from each parent ). while
Homologous chromosome is a pair of chromosomes containing same gene sequence, chromosomal length and posses the same centromere location in each chromosome in the pair.
Hence we can conclude that The diagram that correctly show how heterozygous alleles are found on homologous chromosomes is the first diagram ( Aa ).

18. The structural diagram demonstrates two joined amino acids.
Which arrow points to the peptide bond?
A.3
B.1
C.4
D.2
Answers
Answer:D
Explanation:
The structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.
What is a peptide bond?The resulting bond that is formed between the two amino acids is called a peptide bond, and the resulting molecule is called a dipeptide. As more amino acids are added to the chain, a polypeptide is formed. The peptide bond is a strong covalent bond that holds the amino acids together in the polypeptide chain. It is important for determining the structure and function of proteins.
Hence, the structural diagram demonstrates two joined amino acids, and the arrow points 2 to the peptide bond, which is in option D, as a peptide bond is a type of covalent chemical bond that is formed between two amino acids when the carboxyl group of one amino acid reacts with the amino group of the other amino acid.

What type of cross did Mendel use to determine the probability of offspring when investigating two characteristics at a time
Answers
Answer:
When the offspring in Mendel's experiment were self-crossed, the F2 offspring exhibited the dominant trait or the recessive trait in a 3:1 ratio, confirming that the recessive trait had been transmitted faithfully from the original P0 parent. Reciprocal crosses generated identical F1 and F2 offspring ratios.

Explain the law's of segregation and independent assortment.
Answers
I hope this helps.
Explanation: The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.

2. Why they effect humans - Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
2. Why they effect the ecosystems - Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.

Urey and Miller cooked a "Primordial soup" with Hadean gases, water and electricity to make ___, ___, ___, and ___.
Answers
Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make glucose, acetic acid, amino acids and lipids.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.

Which phrase best defines a prototype?

the criteria established to help solve a problem
O a model from which later versions are developed
Answers
Answer:
A model from which later versions are developed.
Explanation:
A prototype is the rough draft of something in a sense, it is not yet complete and is often only the most basic idea to be expanded on in later versions.
The best definition for a prototype is a model from which later versions are developed. Therefore option D is correct.
A prototype is an early or preliminary version of a product, system, or design that is created to test and evaluate its functionality, features, and feasibility. It serves as a proof of concept and helps in identifying any flaws or areas that require improvement before the final product is developed.
The final product, which has undergone extensive testing and redesign, does not accurately define a prototype because a prototype is not the final product but rather an initial version created for testing and refinement.
Therefore, the most accurate definition, emphasizes that a prototype is a model or early version of a product or system that serves as a foundation for the development of subsequent versions based on testing and feedback.

Answers
Answer:
Binomial nomenclature is basically the scientific classification of organisms, or taxonomy, using a latin name. It uses the genus and the species. For instance, the bacteria Staphylococcus aureus uses binomial nomenclature because Staphylococcus is the genus, while aureus is the species.
Biology Dictionary states, "The genus name is also called the generic name and always begins with a capital letter. For example, binomial name for cats is Felis catus. The genus name must be unique within each kingdom (see image below) but the same genus can be used in more than one kingdom. [. . .] The species within the genus is known by other names depending on the discipline. For general usage, the species is also called the specific descriptor. In botany, it is called the specific epithet and specific name in used in zoology. A species name can be used more than once within a kingdom.The species name always begins with a lower case letter. It can be a noun or an adjective and it must agree with the Latin gender of the genus name; masculine, feminine or neuter. For example, if the gender of the genus is masculine, the species name should end in -us, -a or -um. An example of this is Passer domesticus, the house sparrow, in which Passer has a masculine gender. Endings for feminine species names include -is and -e and -or is used for neuter genders."
