Which statement identifies an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor? the lack of available sunlight for a small sapling to grow an increased amount of rain causing flooding in a local river fertilizer creating a mutation among a farmer's crops overcrowding of a local deer population resulting in fewer resources available
Answer:
fertilizer creating a mutation among a farmer's crops
Explanation:
A genetic factor is one that affects the gene or genome of an individual organism. This genetic factor often influences the observable trait called PHENOTYPE of the organism. In this case, an example of a genetic factor that could influence the growth or development of an organism created by an environmental factor is the "fertilizer creating a mutation among a farmer's crops"
The fertilizer represents the environmental/chemical factor which is creating the genetic factor (mutation) that will eventually influence the growth or development of the crops.
How do animals return water to their environment from their bodies?
Answer: Animals excrete water by respiration and by passing urine.
Why do different individuals of the same species have different traits?
OA. Individuals have differences in their genes that result in protein variations.
OB. Individuals have proteins that produce genes with completely different functions from other individuals.
OC. Individuals have different proteins that cause variations among their genes.
OD. Individuals have different genes that produce proteins with completely different functions from other individuals.
answer : a
explanation : a species shares ALMOST all of the DNA with each other with just small differences
Different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.
Why do individuals of different species exhibit different characteristics?
The species is a group of individuals that can reproduce among themselves and can produce fertile offspring. Individuals of a species have genetic variation among them as they are formed by the process of meiosis.
In meiosis, genes cross over and recombination takes place, resulting in the formation of offspring that show some variation from their parents. These characters or traits are encoded in the gene. When these are expressed in the process of translation, the variation is seen.
This genetic variation doesn't make them reproductively isolated. Example: In humans, there are variations based upon the skin color, face size, height, etc. The variation is seen in genes among individuals but not genes are different.
Hence, different individuals of the same species have different traits because individuals have differences in their genes that result in protein variation. Hence, option A is correct regarding variation.

Specific proteins produced in a cell are directly related to the A. Number of mitochondria in the cell. B. Sequence of sugars and phosphates in the cell. C. Type of ribosomes in the cell. D. Sequence of nucleotides in the DNA of the cell.
Answer:
D. Sequence of nucleotides in the DNA of the cell.
Explanation:
Proteins are a type of biomolecules in living systems responsible for many phenotypic characteristics in organisms. Proteins are synthesized by a process called gene expression, which encompasses transcription and translation.
Using the central dogma of biology to trace, DNA (genes) contains information that encodes the production of proteins in the body. Therefore, the sequence of nucleotide bases in the DNA of a cell determines the sequence of mRNA that will be produced during transcription and ultimately, determines the specific type of proteins (amino acid chain) that will be produced in a cell during translation.

Which question can be used to evaluate reliability of a source?
“Do these results support the author's own opinion?”
“Is this data challenged by anyone in the public?”
“Is this research relevant to me?”
“Who was paid to do this research?”
Answer:
Do these results support the Author's own opinion?
Explanation:
The question can be used to evaluate the reliability of a source is Do these results support the author's own opinion?
In sources (books, articles, etc), reliability implies the information of a source can be trusted. This occurs if:
All the information is based on factsThe information is not manipulated by the author's opinion or interestsIn this context, it is expected the information of the source is objective rather than influenced by the author's opinion. Therefore, one way to check the reliability of a source is "Do these results support the author's own opinion" because if the information is manipulated by a personal opinion, the source is not reliable.
Also, other questions are not appropriate because they are related to other aspects such as relevance, not reliability.

Answer:
Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter. Is smallest to largest.
Explanation:
Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.
What are celestial bodies?A celestial object is an observable cosmic phenomenon that happens naturally. The terms "object" and "body" are frequently used synonymously in astronomy.
A celestial object, on the other hand, is a complex, less cohesively bonded structure that could include numerous bodies or even other objects with substructures, as opposed to a celestial body, which is a single, tightly bound, adjoining entity. Space objects like the Sun, planets, moons, and stars are referred to as celestial bodies or heavenly groups.
They are normally quite far away from us and are a part of the vast cosmos we inhabit. Such objects are scattered throughout the majestic night sky, and when viewed through a telescope, they reveal intriguing worlds of their own.
Therefore, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter Is smallest to largest.
