Nonnative species are not always a negative factor, they become invasive species _________

What are three places where ribosomes occur in a cell?

Strike441 [17]

Answer:

Ribosomes can be found in

1) Cytoplasm

2) Mitochondria

3) On the surface of Endoplasmic Reticulum

Explanation:

In eukaryotes, ribosomes form within the nucleolus, a structure inside the cell's nucleus. As ribosomal proteins enter the nucleus, they join with four rRNA strands to form a whole ribosome. The subunits exit the nucleus through pores and start protein synthesis within the cytoplasm of the cell.

Water moves via osmosis _________. a) from an area with a low concentration of water to one of higher concentration b) from an a

sp2606 [1]

Answer: c) from an area with a high concentration of water to one of lower concentration

Explanation:

Microscopically, we can interpret osmosis as the passage of water through holes in the membrane. These holes are small enough to allow water to pass through, but not to the ions that carry a layer of hydration, that is, a layer of water molecules around them. Water flows through the membrane in both directions. However, the occurrence of osmosis indicates that the flow is more intense in the direction of the less concentrated medium to the more concentrated. Thus, there is an effective flow of water in one of the senses, called osmosis, from an area with a high concentration of water to one of lower concentration.

In fruit flies, the allele for white eyes is recessive to the allele for red eyes. In a generation of fruit flies, 45 males with

Aleksandr [31]

1 is C - see first attachment. Genotypes with Y's represent males, and big R represents red eyes, while little r represents white eyes. For example XRxr is a heterozygous (red-eyed) female, and XrYr is a homozygous white-eyed male.

2 is B because the absence of functional proteins and some ribosomes due to the mRNA strand is not as detrimental as the loss of the entire cell.

3 is B. (The insertion of 3 base pairs into a genetic sequence is the length of a single codon, meaning that only one amino acid in the entire polypeptide was added)
