Answer:

isotonic; the same rate

Explanation:

Cell Theory as as commonly known gives the best definition for cells. All organisms that ever existed are made up of one or more cells. The theory state that the cell is a basic unit, that is of all living things, and that all cells come from cells that have existed.

For cell that is in an isotonic solution,no net flow of water into or out of the cell will be experienced, the volume of the cell is at a state of stability. When the level or concentration of solute in and out of the cell is at the same pace or level, the the cell membrane does not allow solutes to cross, leading to the solution being isotonic to the cell.

Albinism is a recessive trait in humans that is controlled by a single gene. How many recessive alleles must a person have to ha
olga_2 [115]
Answer;
Two recessive alleles are the number of alleles that a person must have to have albinism.

Explanation;
When a trait is recessive, such as albinism, an individual must have two copies of a recessive allele to express that particular trait. Recessive alleles are denoted by a lowercase letter , such as b versus B. Only individuals with a bb genotye will express a recessive trait, hence, the offspring must receive one recessive trait from each parent to exhibit the recessive trait.

frutty [35]

Answer:

Explanation:

First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny

Identify the true statements about RNA interference. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short,
AlekseyPX

Answer:

- Duplex RNA (dsRNA) can suppress the expression of a gene.

- miRNAs are short, single strands approximately 21 nucleotides long.  

- miRNAs suppress gene expression by interfering with transcription.  

- RNA interference can temporarily suppress the expression of a target gene.

Explanation:

The RNA interference (RNAi) mechanism is a naturally occurring biological process by which an organism suppresses gene expression by using sequence-specific small non-coding RNAs that are complementary to RNA (posttranscriptional silencing) or DNA (transcriptional silencing) sequences. Since its discovery, this mechanism has been exploited in molecular biology to control the expression of target genes. There are different classes of non-coding RNAs which are able to trigger RNAi gene silencing: microRNAs (miRNAs), small interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs, only present in animals), etc. During their functioning, these non-coding RNAs are loaded into the RNA-induced silencing complex (RISC) to direct them to target sequences and trigger RNAi (for example, by cleaving target mRNAs). miRNAs are short, evolutionary conserved RNAs, that associate to the RISC complex in order to trigger both transcriptional and posttranscriptional gene silencing. During their biogenesis, small non-coding RNAs are double-stranded RNA (dsRNA), but they lose a strand (the passenger strand) when associate with the RISC complex, conserving only one strand (the guide strand) that bind by complementary base pairing to target sequences (either DNA in the nucleus or RNA in the cytoplasm).
