Answer:
Meiosis results in gametes that are used in reproduction.
Explanation:
- <em>The sperm and egg have twice as many chromosomes as the parental cells</em>. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n.
- <em>Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division</em>. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all.
- <em>Meiosis results in gametes that are used in reproduction. </em>CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.
- <em>Asexual reproduction requires the production of eggs and sperm. </em>INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.
Answer:
Phenotype
Explanation:
Genotype would be something like homozygous recessive, heterozygous dominant, HH, Hh, hh (etc). It describes the genetical pattern in offspring.
Phenotype is the physical description, such as black fur, brown fur, long ears, short ears, indigo petals, white petals, (etc).
<u>Answer:</u>
The codons that signal the end of a polypeptide chain are called the terminators.
<u>Explanation:</u>
The codons that signal the end of a polypeptide chain are called the terminators.
A codon is a series of 3 DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) nucleotides which corresponds to a particular amino acid or just stop the signals which are sent during the protein synthesis.
The terminators are the codons (also called termination codons) which signal the end of the polypeptide chain during the process of translation.
In classical conditioning, the response is elicited by a stimulus that comes before it.
Classical conditioning is an instance of automatic or unconscious learning. This learning process results in a conditioned response by creating associations between an unconditioned stimulus and a neutral stimulus.
In order to expose a naturally occurring reaction to a neutral stimulus initially, we can say that classical conditioning is doing that. Salivation in response to food functioned as both the neutral signal and the naturally occurring reflex in Pavlov's well-known dog experiment. By connecting the neutral stimulus (sound) with the unconditioned stimulus, the tone's sound alone could cause salivation (food).
The first step in the classical conditioning procedure calls for a naturally occurring stimulus that will prompt a response without any further instruction. An example of a naturally occurring stimulus is salivating in reaction to the smell of food.
