Answer:

Option D, has only a single opening

Explanation:

A gastrovascular cavity has only one opening. The food goes in and comes out of the same opening there by making it a two way digestive tract.

However, a digestive tube is a one way digestive tract where the food goes in from mouth (one end) and comes out of anus (second end) . It is also called as alimentary canal

Hence, option D is correct

trapecia [35]

Answer: (c) It generates ATP, which cells can use to do work.

(d) It generates chemical gradients, which have potential energy.

Explanation:

The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.

Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)

In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.

Fresh raspberry contains 80% water. dried raspberry contains only 20% water. what weight of dried raspberry can you get from 36
adell [148]

There 2 ways to solve this

1-      Directly :

80% of water in the fresh berries è 20% of water in the dried berries

36 Ibs of the fresh berries è X Ibs of the dried berries

X = \frac{36 * 20}{80}<span> = 9 Ibs</span>

 

<span>2-      </span>If you do not understand the first method, the second one is more explicit:

First, we gonna calculate the weight of the berries without water (dehydrated):

<span>36 * 80% = 28.8 Ibs    (of water in the berries)</span>

Then:

<span>36 – 28.8 = 7.2 Ibs (of completely dehydrated berries)</span>

 

Next, we gonna add 20% of water in the dehydrated berries:

X (total weight of dried berries) è 100%

7.2 Ibs of dehydrated berries è 80%

X = <span>  </span>\frac{7.2 * 100}{80}   = 9 Ibs
