Answers

Photosynthesis involves two biochemical processes, known as light reaction and dark reaction. During light reaction, the plant absorbs light and turns it into energy. ... Because dark reactions do not require the absence of light, plants will remain healthy when exposed to light 24 hours a day.

Seismographs rely heavily on a pendulum (free-swinging weight) to record measurements. How do you think using a pendulum helps detect small earthquakes?

Answers

Answer:

Generally, a seismograph consists of a mass attached to a fixed base. During an earthquake, the base moves and the mass does not. The motion of the base with respect to the mass is commonly transformed into an electrical voltage. The electrical voltage is recorded on paper, magnetic tape, or another recording medium.

Principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement. The energy from any seismic activity excites this “proof mass” as it is called by geophysicists, making it vibrate. When they detect movement, such as the shifting plates of an earthquake, a pendulum with a pen attached to it graphs the magnitude of the movement. If the pendulum swings vigorously, scientists know that the seismic waves are intense and potentially dangerous. My guess is, when pendulum swings lightly it determines mild intensity and small impact of an earthquake.

1) Read the following paragraph and answer the following questions.
The countries which do not have oil reservoirs in their land, import oil from other countries. But sometimes during transportation of oil through sea routes, accidental oil spill occurs. This oil spilled in the ocean may prove fatal and toxic to aquatic animals. Therefore, removal of this spilled oil is essential for protection of aquatic life. For removing this oil layer, certain microbes like Pseudomonas spp and Alcanivorax borkumensis are used. These microbes have the ability to destroy the pyridines and other toxic chemicals. The hydrocarbonoclastic bacteria (HCB) are able to decompose the hydrocarbons and bring about the reaction of carbons with oxygen resulting in formation of CO​2​ and water. Like oil spills cause damage

to aquatic life, plastic forms the major part of the garbage on the land. Plastics are difficult to degrade as they are made up of PET, by research various species like Vibrio and Ideonella sakaiensis which can degrade PET have been identified. There are certain species of microbes which can decompose rubber from garbage.
a) How are aquatic organisms affected by oil spills in the ocean?
b) Which type of chemical compounds are degraded by microbes used for
clearing oil spills?
c) Name any two species of microbes which can degrade rubber from
garbage.
d) Why should there be a ban on plastic bags?

Answer: See explanation

Explanation:

a) How are aquatic organisms affected by oil spills in the ocean?

Aquatic organisms are affected by oil spilled as it is fatal and toxic to them. It can cause death, habitat degradation, vulnerability to predators and can also lead to the inability to hatch their eggs.

b) Which type of chemical compounds are degraded by microbes used for

clearing oil spills?

The chemical compound degraded by microbes are clearing oil spills are Pseudomonas spp and Alcanivorax borkumensis.

c) Name any two species of microbes which can degrade rubber from

garbage.

These are Vibrio and Ideonella sakaiensis.

d) Why should there be a ban on plastic bags?

There should be a ban on plastic bags as they're difficult to degrade as they are made up of PET.

Some human cells can perform anaerobic respiration for limited amounts of time, such as during periods of heavy exercise. Use the results of your experiment to explain how anaerobic respiration could benefit human survival.

Answers

Answer:

My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.

Explanation: from plato, so change it a bit.

What is anaerobic respiration ?

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.

In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.

Voltage-gated Cl- channels open, triggering the release of neurotransmitter. C. Voltage-gated Ca2 channels open, inhibiting the release of neurotransmitter. D. Voltage-gated Cl- channels open, inhibiting the release of neurotransmitter.

Answers

Answer:

A. Voltage-gated Ca² channels open, triggering the release of neurotransmitters.

Explanation:

For taste mechanisms to function properly, it is necessary the activation of taste receptors.  

Through the activation of taste receptors, transduction cascades occur, involving ion channels that are located in the apical or lateral membranes. There occurs a subsequent release of chemical neurotransmitters that send signals to the control centers.

Salty and sweet flavors produce the membrane depolarization that results in Ca+ ions´ entrance to the cell. Ca+ initiates the release of neurotransmitters. Afferent gustative neurons receive the message and send it to the control center, the encephalon. After that, gustative cells go back to the initial state, repolarizing.

Which of the following is NOT an example of evidence that supports the theory of evolution?

C. unnecessary or nonfunctional organs in modern species
D. fossils of the same species found diverse geographic locations

Answers

The answe is D because location has nothing to do with genetics

The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

What do you mean by Evolution?

Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.

Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.

Therefore, the statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.

What should she use as a positive control

Answers

Answer:

Human cytochrome C

Explanation:

The enzyme-linked immunosorbent assay (ELISA) is a technique widely used to detect and measure antibodies and antigens in biological samples. This technique can be used to diagnose different diseases by detecting antigens that bind to antibodies. The ELISA test consists of a plate with a capture antibody against the antigen of interest coating the plate. Subsequently, the target antigen is detected by adding a detection antibody labeled with an enzyme (e.g., alkaline phosphatase) that binds to this antigen. Finally, a particular substrate (e.g. ABTS) is added to the plate and the subsequent reaction converts it into a colored product which can be easily detected using microplate readers. In this case, the positive control will be human cytochrome C which will bind to specific antigens in order to evidence the presence of this molecule in the sample.
