The blockage of cerebrospinal fluid (csf) outflow in the brain can cause accumulation of fluid, resulting in cranial enlargement
alisha [4.7K]

The correct answer is hydrocephalus.

Hydrocephalus refers to the condition in which the accumulation of fluid takes place in the ventricles (cavities) deep inside the brain. The excess fluid enhances the size of the ventricles and applies pressure on the brain. The cerebrospinal fluid usually flows via the ventricles and bathes the spinal column and the brain.

Explain why the number of mice in a grassland ecosystem is greater than the number of hawks
Westkost [7]
Let's go back to "Darwin's" evolution theory. mice can be smarter than the average hawk, they are fast, have underground protection from cold,heat, rain,ECT..and they scavenge during p.m. hours, not all hawks are nocturnal, that's why owls are nocturnal. This cycle ensures enough food source for all predators. A hawk can consume at least 6 mice per day/night. rodents are natural prey for all preditors., even coyote. hope this helps, plus mice reproduce quickly compared to preditors.
hope this helps..

A student makes a claim that a cell is undergoing the process of transcription what evidence would be present to support this cl
MaRussiya [10]

Question: A student makes a claim that a cell is undergoing the process of transcription. What evidence would be present to support this claim?

A) tRNA with anticondos is carrying amino acids to the ribosomes.

B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.

C) Ribosomes are reading mRNA molecules three nucleotide at a time to synthesis proteins

D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production

Answer:

The evidence that the student have to produce as an evidence is the "RNA polymerase using the single strand of the DNA molecule as a template for mRNA production."

Explanation:

We know, that in transcription the genetic information from the DNA is copied into RNA for production of the proteins.  According to various research methods, to know whether the cell is going through the transcription, a student can use the bacteriophage coat protein, which must have labelled with the fluorescent protein for studying it under microscope. After, this has been done, in the right location stem loop present, the RNA will be seen initiating of the elongation step, hence the transcription site will be more visible when the coat protein binds to the new RNA, which has happened in the transcription site. We can know see the transcription as fluorescent which will help the student to determine the process of transcription in the cell. Presence of promoters are important to demonstrate the process.
