Biology
1 answer:
Artemon [7]3 years ago
8 0

Answer:

- Physical and chemical barriers

- non-specific innate responses

- specific adaptive responses

<u>The differences are...</u>

The first barrier is the physical and chemical barrier. It is the first line of defense when in contact with outside sources, this can be through the skin, earwax, nose-hair, etc.

The second barrier, the non-specific innate response, is after these outside sources have somehow managed to pass through the first barrier. They come into contact with cells and enzymes that help to defeat them.

The third barrier, the specific adaptive response, is the body's way of dealing with pathogens that the body has encountered before. (B cells activate)

Design an experiment where you would determine how quickly lactaid works to break down milk sugar at different temperatures
choli [55]
1. Gather 11 cups and then fill each cup with 5 ounces of whole milk, next is take the first cup to add a known quantity of lactaid. As a control, take another cup and do not add any lactaid. After 1minute, pour a known quantity of Benedicts into cups of milk. Record the color (blue is the least amount of glucose progressing to green, then yellow, orange, red, and brick red/brown). Take another cup of milk and then add the lactaid and wait 5minutes next is add the Benedicks. Record the color, repeat steps 7-10 adding 5minutes each time until there are no cups left (15 minutes, 20, 25,30,35,40,45).

Which factor does not greatly influence the rate of
jonny [76]

Answer:

a. transcription

Explanation:

<em>Sugar transport in phloem is referred to as pressure flow and it involves the movement of sugar through the phloem vascular tissue from the regions where sugar is synthesized (by photosynthesis) to other parts of the plant's body that require sugar.</em>

The parts of plants where sugar is synthesized (usually the leaf) is known as sugar source while the parts where they are transported is referred to as the source. Sources are usually areas of of high osmotic concentration and high water pressure while sinks are usually areas of low osmotic concentration and low water pressure.

<em>Hence, sugar transport in the phloem can be said to be influenced by the rate of sugar production at the source (rate of photosynthesis), turgor pressure as well as sugar concentration in sinks and sources.</em>

The only option that has no known effect on sugar transport in the phloem is transcription.

The correct option is a.
