Design a laboratory-based experiment to test the hypothesis that algae need light to grow.

Answers

The same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

What is algae growth?

The growth of algae is the process by which the organism increases in size. Now we know that that the algae is photosynthetic hence light must be required for its growth.

In order to verify this, the same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.

The results of this experiment must confirm that the algae exposed to light grows better than the algae that was not exposed to light.

LeeAnn wants to organize her data from researching the effect of hours of sunlight on plant growth to see if there is a trend in the data. Which would be the best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth?
in a line graph
in a data table
in a bar graph
in a pie graph

Answers

The best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth will be a line graph.

When comparing how numerous items change over time in relation to one another or tracking smaller changes over longer periods of time, line graphs (also known as line charts) work well. The crucial term "over time" is your cue to think about creating a line graph for your data whenever you hear it. Because they are straightforward, simple to grasp, and efficient, line graphs are often used and effective charts.  Hence LeeAnn can display her data using a line graph because plant growth is a small change and has to be recorded for a longer period of time.

Answers

1°C increase of temperature can effect the biodiversity of the habitat in terms of number of populations and number of individuals in the population, it can either increase or decrease the population growth.

1°C increase in temperature on biodiversity can increase or decrease the population growth.

Population growth  or change in number of individuals in the population of some organisms increases or decreases with the increase in temperature. The population of certain species such as Nassuar grouperand, Queen angelfish increases with the increase in temperature while some species such as sponges and algae decreased in population with the increases in temperature. This is because some species need high temperature to grow, so even a 1°C increase in temperature increases the population while some species need low temperature to grow, so high temperature kills them and population is decreased.

Explain what causes menkes syndrome include in your answer the symptoms and life expectancy of the affected person

Answer:

Menkes disease is caused by a defect in the ATP7A gene. The defect makes it hard for the body to properly distribute (transport) copper throughout the body. As a result, the brain and other parts of the body do not get enough copper, while it builds up in the small intestine and kidneys. Menkes syndrome causes impaired copper absorption. This results in changes in the arteries and deterioration of the brain. Menkes syndrome is rare. Most children born with Menkes syndrome have a life expectancy of < 4 years.

Carbon fixation occurs in the second stage of photosynthesis, during the light-independent reactions of the Calvin cycle. In the first step of this cycle, the enzyme Rubisco adds CO2 to the energy-rich compound ribulose 1,5-bisphosphate, ultimately producing two molecules of 3-phosphoglycerate. In a culture of green alga that is carrying out photosynthesis in the presence of CO2 in the laboratory, what would happen to the levels of ribulose 1,5-bisphosphate and 3-phosphoglycerate in the minutes after the lights were turned off and the cultures were plunged into darkness

Answers

Ribulose 1,5-biphosphate will be depleted while 3-phosphoglycerate will accumulate.

Carbon fixation

The first step of the carbon fixation during which Rubisco adds CO2 to Ribulose 1,5-biphosphate to produce 2 molecules of 3-phosphoglycerate requires energy molecules from the light reaction.

In the subsequent steps, Ribulose 1,5-biphosphate is regenerated in a step that requires energy molecules from the light reaction.

Thus, in the first few minutes of turning off the light, the available energy molecule from the light reaction will be used up to produce 3-phosphoglycerate. However, the regeneration of Ribulose 1,5-biphosphate will become impossible.

the diaphragm is innervated by the __________ nerve, which allows it to contract.

Answers

The diaphragm is innervated by the phrenic nerve, which allows it to contract.

What is phrenic nerve?  

The C3-C5 spinal nerves, which are parts of the cervical plexus, give rise to the phrenic nerve, a mixed nerve. It begins in the neck and travels through the thorax vertically before terminating on the diaphragm.

The phrenic nerve is bilateral, there are some significant distinctions between the left and right counterparts in terms of its courses and interactions with surrounding structures.

The primary purpose of the phrenic nerve, which makes it an essential part of the physiology of breathing, is to deliver the full motor innervation to the diaphragm.

Diaphragm is controlled by the phrenic nerve (the large dome-shaped muscle between abdominal and chest cavities). It is necessary for breathing. Diaphragm contracts as a result of signals sent by nerve (become thicker and flatter). This motion makes room for  lungs to expand and take in air (inhalation).

Explanation:

hope it is helpful

Answer:

Explanation:

: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.
