Why are most cells small?
(Science)
Biology
1 answer:
Margarita [4]3 years ago
6 0

If the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.

simpler answer: Cells are small because they need to keep a surface area to volume ratio that allows for appropriate intake of nutrients while being able to eliminate the cells waste.

What are 2 conditions to enhance infant memory?
andrezito [222]

1. Establish routines. Young children thrive on them, and they make perfect fodder for enhancing your child's memory.

2. Play memory games. Ask questions when you're out and about. For example, if you're passing a friend's house, ask, "Who lives there?" Games like this give children experience in recalling information.

3. Demonstrate how to perform tasks. Babies model their parents' actions. If you want your child to learn how to do something, such as stack one block on another, show him how and then give him a turn.

4. Talk with your child about her experiences. Focus on events that resonated strongly with her, such as a trip to the zoo. As she gets a little older, help her make stories out of her recollections.

Create an experiment where you would use both a Southern blot and a Northern blot to determine if a newly isolated bacterium con
natta225 [31]

Answer:

■Gene sequences would be used to make Probes for both the Southern and Northern blots.

■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium

■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism

■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present

■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one

■since all the genes present in the genome couldn't be identified, the northern would be important to work on

■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.

ZanzabumX [31]

Answer:

Levothyroxine is a thyroid hormone used to treat hypothyroidism. Administration in the morning is preferred to prevent insomnia.

Explanation:

Levothyroxine is generally recommended for patients with thyroid problems. When a patient needs to take this medicine, it is important that they follow certain recommendations: It is important that levothyroxine is taken every day, preferably at the same time, avoiding long delays or forgetfulness. Another important caution is that levothyroxine should be taken fasting, because its absorption depends on the acidity of our stomach, so it is recommended that it be taken in the morning, soon after the patient has wakes up.

Molodets [167]

When a person is anxious or fearful, the autonomic nervous system shunts blood away from peripheral veins to the core of the body - TRUE

  • Sympathetic stimulation of blood vessels causes arteries and arterioles (resistance vessels) to constrict, increasing vascular resistance and reducing distal blood flow.
  • The increased vascular resistance that results from this across the body raises arterial pressure.
  • When our bodies shift into superman mode, the second signal is transmitted to the hypothalamus, where it activates our autonomic nerve system,
  • which is in charge of the fight-or-flight impulse.
  • Our bodies receive an adrenaline boost as well as an increase in heart rate and blood pressure. When you are afraid, you get that rush.
