Which pair of terms concerning the osmotic effect of a solution on red blood cells is mismatched?

QveST [7]

Even though there are no choices given in this particular question, the principle of osmosis is very easy to understand.

When we talk about osmosis, we are referring to the movement of water from a low concentration to a higher concentration. This is different from diffusion, which talks specifically about the movement of solutes in the solution (from a higher concentration to a lower concentration.)

When an RBC is placed inside a hypertonic solution, the water inside the RBC will go out thereby shrinking the RBC.

Inside an isotonic solution, the RBC will remain the same because the concentrations are equal.

Inside a hypotonic solution, the RBC will lyse or explode because water will move from the solution going inside the RBC.

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mi

MaRussiya [10]

Answer:

la vida no podría continuar sin los procesos de división celular

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.

Which feature of Earth is part of the geosphere?

notka56 [123]

Answer:

Rocks

Explanation:

Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the part of the Earth that includes all the rocks, minerals and landforms of the surface and interior that make up the Earth. It starts at the ground and extends all the way down to Earth’s core.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!
