In a closed system, the total energy prior to an energy transformation is _______ the total energy after. A. equal to B. unrelat
nikklg [1K]
Hey there mate!

Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.

But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.

So, it really depends whether the system closes up, or whether it would be free of energy.

So, in this case, your correct option to this answer would be (option A).

<span>In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after. 

I hope this helps you!</span>

This bonds to cytosine (C) in DNA.
shtirl [24]

Answer: <u>Guanine </u>

According to Chargaff's rule, the base pairing in the DNA and RNA is fixed. Adenine always pairs with Thymine in DNA and Uracil in RNA. Guanine pairs up with cytosine. This complementary base pairing is universal and constant. That's why amounts are also equal. It means if cytosine is 20% in any DNA sample, then amount of guanine would be 20% as well.

you find eggs of a bot fly sticking to the hairs of your horse's ankles. what subfamily do these eggs likely belong to?
bazaltina [42]

Where on find eggs of a Bot Fly sticking to the hairs of your horse's ankles. The subfamily that these eggs likely belong to are: Gasterophilinae.

<h3>What is Gasterophilinae?</h3>

The Gasterophilinae are a subfamily of the Oestridae that comprises huge, parasitic flies; this group was previously classified as a family, but all subsequent classifications locate them squarely within the Oestridae. Many members of this subfamily spend part of their larval lives in herbivore digestive systems.

Gasterophilus intestinalis, often known as the horse bot fly, is a species of insect in the Oestridae family that may be found all over the world. The adults, which resemble bumblebees, are most active throughout the summer.

Female botflies deposit eggs on blood-sucking arthropods like mosquitoes and ticks to reproduce. When afflicted arthropods attack a person or another mammal, larvae from the eggs are released. A botfly larva burrows into subcutaneous tissue after entering the host's skin through a bite wound or a hair follicle.

Chief cells secrete inactive pepsinogen in order to prevent acid erosion inside of the chief cells. True or False
Vladimir [108]

Answer:

The statement is false.

Explanation:

At the base of the oxyntic gland, in addition to the parietal cells, the chief cells (peptic cells) are located, mainly in the lower half of the gastric glands, these cells have large basophilic zymogen granules, more prominent in the apical region and responsible of the secretion of pepsinogen proteolytic enzymes, a relatively constant fraction of pepsinogen I released by the chief cells is absorbed by the blood instead of passing into the gastric lumen. The stomach acid transforms pepsinogen into pepsin, which breaks down proteins in food during digestion.
