almond37 [142]

Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?

a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.

b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.

c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.

d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.

Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>

Explanation:

By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.

If you were to add one of the eight citric acid cycle intermediates to the culture medium of yeast growing in the laboratory, wh
raketka [301]

Answer:

B) The rates of ATP production and carbon dioxide production would both increase.

Explanation:

The citric acid cycle is the second stage of aerobic cellular respiration. It includes complete oxidation of acetyl CoA into CO2 and H2O. During the citric acid cycle, NAD and FAD serve as electron acceptors. Reduction of these reducing powers forms NADH and FADH2 which in turn enter the electron transport chain for their oxidation and drive the process of as many as 32 ATP molecules by oxidative phosphorylation. On the other hand, fermentation forms of 2 ATP molecules and a few or no CO2 molecules.

Therefore, if one of the eight intermediates of the citric acid cycle is added to the medium, the yeast cells would perform aerobic cellular respiration and would form more CO2 and ATP molecules than the ones formed during the process of fermentation.

Based on your research what are 3 reasons plants are propagated asexually?
liubo4ka [24]
The 3 reasons plants and propagated asexually are:

1. To preserve the genetic characteristics of a particular plant

2. Propagate plants it do not produce viable seeds for example: (bananas, pineapple, seedless grape etc.)

3. Produce seed that is difficult to germinate or it has a very short.

IrinaK [193]

The endosymbiotic hypothesis explains that how eukaryotic cells might have evolved chloroplasts and mitochondria within their cells.  

The endosymbiotic hypothesis states that the eukaryotes have developed via a procedure whereby distinct kinds of free-living prokaryotes became assimilated within the bigger prokaryotic cells and ultimately evolved into chloroplasts, mitochondria, and various other organelles.

Which describes the modern classification system?
Feliz [49]
The question must refer to the modern classification system in biology.

It started with the work of Linnaeus - so its early version can be called a Linnaean classification - but right now it has been expanded and changed to fit the evolutionary relationships between the species - which is the best description, i.e. the answer is "it is based on the evolutionary relationship of the species"
