Answer:
Gene: The hereditary material made up of alleles.
Alleles: The alternative forms of a gene.
Dominant: An allele or trait that masks the effect of recessive allele or trait.
Recessive: An allele or trait that gets suppressed by the dominant allele or trait.
genotype: The genome of a particular organism of the genes which make up an organism.
phenotype: The physical traits or characteristics of an organism.
test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.
law of independent assortment: Alleles of different genes get assorted independently into gametes.
law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.
product rule: Independent evens can be calculated by multiplying the independent probabilities.
Addition rule: The probability which shows that one event would occur in a mutually exclusive event.
co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.
incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
Explanation:
Answer: B
Explanation:
They inject their DNA into the cell, which reprograms that cell to become that virus. This is why viruses are so deadly and can spread throughout the body and to others easily, and efficiently.
Answer:
The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.
Explanation:
Annelids, such as the earthworm, have a variety of sensory cells:
- <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.
- <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
- <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
- <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.
The tegument is very rich in free nervous terminations, which functions might be tactile.
