The Image Below Shows One Muscle Cell. Please Choose The Name Of The Structure That Is Labeled A. 1.

Answers

Answer 1

The name of the structure labeled as A is 'myosin'. Moreover, the name of the structure labeled as B is 'actin'.

A sarcomere is the basic unit of muscle contraction. This unit is defined as the region between two Z-lines.

Band A is a central band composed of the thick filaments of myosin.

Moreover, the sarcomere also has two halves of a band known as I-band, which consists of thin filaments of actin.

Muscle contraction is caused by the interaction between actin and myosin protein filaments in the sarcomeres.

What happens when oxygen, carbon dioxide and glucose molecules diffuse across the cell membrane? Explain in your own words

Answers

Answer:

Simple diffusion is responsible for the spread of an air freshener through a room, or of a few drops of dye to eventually turn a glass of water a uniform color. Molecules naturally disperse from areas of higher concentration to lower concentration.

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?

Answers

Although I could not locate the options in order to provide a ranking, I can offer the insight that a hypertonic saline solution will be the most effective form of treatment.

I believe you are referring to the full case study which says :

"Your goal is to stop Clark's seizures by restoring equilibrium between the blood and the matrix. Based on the data collected and what you have learned about osmosis and the three treatment options, rank the treatments from most effective to least effective. What do you predict?"

A hypertonic saline solution is used to draw water out of cells by creating an increased concentration of solute in the blood, forcing the water out of the cell through osmosis.

Clark's seizures may be caused by Increased solute concentrations in the brain which forces water from blood to move into the brain, thus increasing the matrix pressure. This then causes the neurons to fire at an increased rate and leads to the seizures Clark was experiencing.

Hypertonic saline can be used to increase solute concentrations, in this case, Sodium, in the blood which forces water to move back into veins. Thus returning Clark to a balanced level of blood and matrix water levels, and may reduce his likelihood of seizures.

HACCP : hazard analysis critical control point.

It is a management system that addresses food safety through analysis and control of biological, physical and chemical hazard.

There is a working flow of HACCP that ensures food safety begins from raw material production, procurement, handling, to manufacturing, distribution and consumption of the finished food product.

Hence, it can be said that HACCP system begins when food is delivered to the store and served to the guest that is consumption of the final product.

How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)

Answers

Answer:

the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.

The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.

What is pH?

a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.

Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.

The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.

Answers

A way you could test if bacteria are different is through Gram Staining

Despite all bacteria are prokaryotic organisms, there are thousands of bacteria species and each species has different characteristics.

Moreover, bacteria are classified into two main groups:

Gram-negative bacteriaGram-positive bacteria

These differ in their structure as gram-positive bacteria have a thick peptidoglycan layer, while gram-negative bacteria have a thin peptidoglycan layer and an external layer.

This key difference is essential when classifying bacteria because there are specific species for each type. Moreover, this can be tested through Gram staining, as this will show gram-positive bacteria as purple and gram-negative ones as pink or red.

Which statement correctly describes how energy is made in photovoltaic cells and how energy is made in photosynthesis?
A.photovoltaic cells can only make energy that does not need light for photosynthesis can only make energy that needs light.
B.photovoltaic cells in photosynthesis can make energy that need light and energy that does not need light. C.photovoltaic cells need light to make energy by photosynthesis to make energy that needs light and energy that does not need light. D.photovoltaic cells can make energy that need light in energy that does not need light for photosynthesis can only make energy that does not need light

Answers

Both photosynthesis and photovoltaic cells need light in order to produce energy, though photosynthesis does have a process that can occur in the absence of light, so option C is correct.

Photovoltaic cells are man-made panels that use solar light to create energy. They do this by taking advantage of the natural ability of some materials to absorb the photons in sunlight and use them to release electrons. The release of electrons generates an electric current which produces energy.

Meanwhile, photosynthesis is a naturally occurring process by which plants and a handful of other organisms produce energy. Photosynthesis also requires the presence of sunlight to function. However, photosynthesis also has a dark phase where the chemical reactions continue despite the absence of light. For these reasons, option C is correct whilst the rest are false.

Brain stem is made up of pons and the medulla oblongata.

The cerebellum is  well known to just  be the  part of neuronal circuitry  that is just activated in the respiratory challenges that are  such as  the hunger for  the air but are not been made to be involved in control of  the spontaneous and the  unobstructed breathing .
