A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the
container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant's leaves on days 1 and 2, but no
bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be
added to the water in order for the bubbles to reappear? (1 point)

Answers

Answer 1

Answer: Are there any options? you either add C02 because it has run out gas or you and in minerals that also contain C02.

Explanation: you need C02 to have photosynthesis, so with a closed off lid,  the gas is going to eventually run out.

Answer 2

Carbon dioxide should be added to the water in the container in order for the bubbles to reappear in the glass container while placed in sunlight. Carbon dioxide is a component of photosynthesis.

What is Photosynthesis?

Photosynthesis is the process by which plants prepare their own food in sunlight and in the presence of carbon dioxide gas. Photosynthesis process takes place in the chloroplast of cells.

Photosynthesis is an anabolic reaction in which carbon dioxide and water reacts in the presence of sunlight which is trapped by the chlorophyll present in the leaves of plant to produce glucose (carbohydrate) and oxygen gas, which is later utilized in the process of respiration.

Answers

Given what we know, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours.

What is TCS food?TCS food refers to food that must be stored in temperature-controlled environments to ensure safety.These foods, if not stored properly and at the correct temperatures can cause sickness to the consumers.

Why does it need to be date-marked?The reason the foods need to be date-marked is to relay information to the potential consumer as to by when the food should be consumed. This is done to ensure that if stored correctly, the food does not have time to spoil and cause health risks for consumers.

Therefore, we can confirm that ready-to-eat TCS food must be date marked if it will be stored for longer than 24 hours in order to protect the health of the consumers.

c. How successful has it been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?

d. What can you do personally to help alleviate the problem of acid rain?

3. Find two examples of actual ecological places that have been affected by acid rain. Tell their location and describe what happened.

Answers

Acid rain is formed when gases such as SOx and NOx are released by burning fossil fuels.

The clean air act has to do with the reduction of the gases that lead to acid rain such as SOx and NOx. The full implementation of the legislation ought to reduce the occurrence of acid rain.

However, since the introduction of the act in 1990, reduction in acid gas pollution has not reduced significantly since acid gases are still produced by the burning of fossil fuels.

To help alleviate the problem of acid rain, I must reduce my use of gasoline powered vehicles and embrace vehicles that depend on renewable energy sources and clean fuels such as hydrogen fuel.

Eastern Europe countries such as Poland and Scandinavia have been severely affected by acid rain. The pH of water bodies in these areas are unusually low.

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D

Answers

Option D has the highest concentration of lactic acid in the student's muscle tissue.

We can arrive at this answer because:

Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.

As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.

It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.

Answers

Neurons are cells in chauge of synapsis. a)cell body  / b)myelin sheath  / c)synaptic terminal  / d)axon hillock  / e)nucleus  / f)location of voltage-gated channels  / g)location of ligans-gated channels  / h)axon  / i)dendrite

-------------------------------

Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.

Neurons transmit nervous impulses.

Every neuron forms connections with other neurons. These connections are known as synapsis.

During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.

The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.

Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.

This binding produces a depolarization of the cell called an excitatory postsynaptic potential.

Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.

When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.

Besides, there is an increase in sodium permeability.

Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.

The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.

The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.
