<h2><u>Answer:</u></h2>
The correct option is B (in one direction)
<h3><u>Explanation:</u></h3>
The two atrioventricular (AV) valves, the mitral valve (bicuspid valve), and the tricuspid valve, which are between the upper chambers (atria) and the lower chambers (ventricles). The two semilunar (SL) valves, the aortic valve and the aspiratory valve, which are in the conduits leaving the heart.
So the atrioventricular valves enables blood to spill out of the atria to the ventricles. be that as it may, regularly keeps the reverse of blood and opening. ... these valves to open and after that blood goes through from the atria into the ventricles. and afterward when the weight is developing in the ventricles.
Answer:
Animals are adapted to the complex chain food since when they were no manufactured to the their food system. Without breakdown this complex food chain can not digest without breakdown.
Explanation:
Earthworm alimentary canal:
- Earthworm have a segmentation of well developed characteristics of all animals.
- The alimentary canal of earth worm as well as flatworm consists of buccal cavity, mouth, esophagus, crop, intestines', gizzard, and anus. The digestion occur extracellular that means the digestion occur outside the cells.
- Cockroach is an omnivores. It ranging from starchy to the sweet things to the paper and clothes etc. It suits its diet. Its alimentary canal consists of Foregut, midgut and the hindgut.
- Both are different in their structure as well as in their alimentary canal.
Answer: Cellular respiration is the process by which microorganisms obtain the energy available in carbohydrates. They take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrate and release the energy. The energy is generally not needed immediately, so it is used to combine ADP with phosphate ions to form ATP molecules. During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons. This oxygen gas is identical to the oxygen gas given off in photosynthesis.
Explanation:
Hey there!
Well, qualitative observation is basically a measurement and it can be measured exactly.
Out of all the choices, your answer is C. Joseph is observing the color of the reaction mixture to see whether proteins are present in the given solution. This is because you can quickly tell if there are proteins present or not.
Options A and B are not as easy to measure.
Hope this helps you.
Have a great day!
