what is excretion meaning

Answers

Answer 1
Definition of Excretion

Excretion is a process in which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys, and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. 

In simple terms, the process of eliminating or expelling waste matter.

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.

How HACCP system works?

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.

The Centers for Disease Control (CDC) collect vast amounts of data. For this activity, we want you to use their Natality Information database to test various hypotheses about birth. For the following five issues, please create a hypothesis and then use the database to collect information about the issue. Once you the data is displayed, record it and indicate whether your hypothesis was supported by data.
The database functions in this manner:

Upon going to this website, you will need to comply with the CDC requirements for using the database. Because this is a school activity, you will be fine. Click I Agree.
The top section (Section 1) of the query engine will allow you to determine how your data sets will be displayed. You will want to Group Results by State for the queries you will perform.
Be sure to select the correct measure for your question/hypothesis. Select only one measure for each query.
Section 2 allows to select individual states or multiple states for comparison. If you have selected states in Section 1, you can run multiple data sets here and see them displayed by state. If you did not, the only way to see individual state data is to run the query one state at a time.
The remaining sections include the conditions you can use for comparison. You will need to find the appropriate section for the condition you are testing for. Once you have found it, go ahead and run your query by clicking Send.
Let me talk you through the process. Seriously, watch this video explanation of what you're doing.

Here's an example. Which state, Utah or New York, has the highest average age for mothers giving birth?

Hypothesis: New York has the highest average age for mothers giving birth.
Data (based on the following settings)
Section 1: Group Results by State; Measure: Average Age of Mother (years)
Section 2: Select Utah and New York

Run the report (click Send) and the data says that New York's average age of mothers is 30.26 and Utah's is 28.59
Supported hypothesis: Yes

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.

according to the induced fit hypothesis of enzyme catalysis, _____.

Answers

Answer:

the binding of the substrate changes the shape of the enzyme's active site

Explanation:

According to the induced fit hypothesis of enzyme catalysis, the shape of the active site of an enzyme changes in response to the binding of a substrate molecule.

What is induced fit hypothesis of enzyme catalysis?

The active site, which is the region of the enzyme that interacts with the substrate, adjusts its shape to fit the substrate more snugly. This change in shape enhances the formation of the enzyme-substrate complex, leading to more efficient catalysis and faster reaction rates.

The induced fit hypothesis suggests that the active site is not a rigid structure, but rather, is flexible and dynamic, adapting to the substrate to optimize the reaction.

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.

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.
