In a population of wild bees, a mutation resulted in slightly larger wingspan in some of the bees. This larger wingspan made the

bees more efficient in their flights to flowers to collect nectar. Thus, these bees became more successful at surviving and reproducing. This trait was passed on to offspring, and eventually the larger wingspan variety of bee replaced their smaller-winged relatives completely. Because this mutation produced a specific wing trait that was passed onto offspring, the mutation must have occurred ____.

Answer:

In reproductive or sexual cells

Explanation:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. These germ cells suffer both mitosis (to form more sexual cells) and meiosis (giving place to haploid gametes: sperm and egg cells, through the gametogenesis process). Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.

Gametes from each parent will merge in the process of fecundation, during which a new diploid cell called a zygote emerges through fertilization. The zygote is a complete cell from the structural point of view that suffers successive mitosis to form the new organism.

Any cell in the organism might suffer mutation.

  • If the mutation occurs in the somatic cells, it will produce a population of identical mutated cells in that organism. However, this mutation in these cells is not inheritable. By definition, mutations in somatic cells do not inherit because these cells do not produce progeny.
  • If the mutation occurs in the germinal line, in the germ cells, or the sexual cells, this <u>mutation will pass to the offspring</u>. The organism with mutated germinal cells might express a normal phenotype, but this mutation will be detected in the progeny.

Explanation:

Although low dose of aspirin can be used during pregnancy to prevent or delay onset of preeclampsia, high dose or continuous use of it is not advised during pregnancy

What would happen to an animal cell with an internal salt concentration of 70% if it were placed in a salt solution with a conce
Vlada [557]

Answer:

It will swell and eventually burst because water from the environment is flowing into the cell

Explanation:

This question is describing OSMOSIS, which is the movement of water from a region of high concentration to a region of low concentration across a semi-permeable membrane. The osmotic process is facilitated by the formation of an OSMOTIC GRADIENT i.e. difference in concentration between the two sides of the membrane.

In this case, an animal cell containing an internal salt concentration of 70% (hypertonic) were placed in a salt solution with a concentration of 20% (hypotonic), OSMOSIS will occur in the sense that water will move from where it is more concentrated (salt solution) into where it is less concentrated (animal cell), hence, the animal cell will SWELL AND EVENTUALLY BURST.

coat color in mice involves the interaction of multiple genes if a mouse has two recessive alleles for coat colorit is always al
AleksAgata [21]

Answer:

Epistasis

Explanation:

In epistasis, the interaction between genes is inimical, such that one gene masks or interferes with the expression of another. “Epistasis” is a word coined of Greek roots that mean “standing upon.” The alleles that are being masked or silenced are said to be hypostatic to the epistatic alleles that are doing the masking. The cause of the biochemical basis of epistasis is a genetic pathway in which the expression of one gene is dependent on the function of a gene that precedes or follows it in the pathway.

The example of epistasis given is the pigmentation of mice. we were told that "if a mouse has two recessive alleles for coat color,  it is always albino no matter what the genotype of other genes involved in coat color"

Let say recessive allele (rr), it is always albino irrespective of other type of other genes, this is true in the stance that epistasis can be reciprocal such that either gene, when present in the dominant (or recessive) form, expresses the same genotype.

20 POINTS!!!What describes the diet of a saprotroph?
Katena32 [7]

Answer:

Dead plant matter

Explanation:

Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
