please help​

Answers

Answer:

Informercials, like the class Shamwow Informercial are an example of how structure and technique can have a huge effect on how a user or prospect is driven towards taking a specific action like clicking a buy button.

Informercials follow a specific structure that any small business can use to drive action but few businesses ever consider using it when they pitch their product or service. In this post, we'll describe the structure and give you examples of how you can use it in your business.

The question above wants to test your ability to create an infomercial using your creativity. For that reason, I can't create an infomercial for you, but I'll show you how to create one.

First, you need to know that an infomercial is an advertisement made to be played on television, usually associated with sales, but can be used to present information.

Based on this, you should create your newsletter as follows:

Establish the element that your infomercial wants to present.Show what are the issues related to this element.Show the solutions you want to present to these problems.Show how these solutions are truthful and reliable.

In the image below, you can see a tutorial on how to make an infomercial.

Similarities and Differences in the order in which electrons are filled in s and d subshells.​

Answers

Answer: Each orbital is found on different areas of the periodic table. The s sublevels are found on the first(left) and last(right) columns of the period table which hold a maximum of two electrons since it only has one orbital. First, each orbital can hold a maximum of two electrons. The other three sublevels: p, d, and f respectively have more orbitals, which is why they can hold more electrons. These sublevels of orbitals stand for sharp(s), principle(p), diffuse(d), and fundamental(f) (these are simply the categories of orbitals).

p has 3 orbitals so it can hold 6 electrons max. d has 5 orbitals so it can hold 10 electrons max. f has 7 orbitals so It can hold 14 electrons max.

Here is a picture of these orbital groups so you can understand a little better:

Spongebob completed his experiment. He wrote a brief summary about the investigation. He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation. Spongebob utilized which step of the scientific method?

Answers

Answer:

In a 7-step scientific method, Spongebob utilized the 6th step when He wrote a brief summary of the investigation, and Spongebob utilized the 7th step when He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation.

Explanation:

Scientific Methods are organized ways employed by scientists to tackle problems by providing solutions to the problem or make hypotheses to which other scientists build on to provide solutions to the problem.

The steps of the scientific method are:

Step 1- Understand the Problem

Step 2-  Make research

Step 3- Hypothesis.

Step 4- Conduct an experiment to test the hypothesis

Step 5- Observations.

Step 6-Results/Conclusion.

Step 7- Communicate your research

When Spongebob wrote a brief summary of the investigation, which means he had already conducted an experiment and had already made necessary observations and data collection, so he was at step 6. At step 6, he had analyzed the data collected.

When Spongebob determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation, then he was at the final step of the scientific method. Step 7 tells whether the hypothesis is true or false.

Explanation:

Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances.

Examples are flammability, rusting of iron, precipitation, decomposition of water by an electric current.

The ability to decompose and reactivity are chemical properties of a substance.

Physical properties tells us everything about what a substance is when no change is occurring to its constituents. Examples are state of matter, color, odor, taste, texture, hardness e.t.c

state four difference between the series and parallel connection?​

Answers

Answer:

1- The components in a series circuit are arranged in a single path from one end of supply to another end. However, the multiple components in a parallel circuit are arranged in multiple paths where the two end terminals of the battery.

2- In the series circuit, different voltage exists across each component in the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.

3- The equivalent resistance in case of a series circuit is always more than the highest value of resistance in the series connection. While the equivalent resistance in the parallel circuit is always less than any of the individual resistances in parallel combination.

4- A fault in one of the components of the series circuit causes hindrance in the operation of a complete circuit. As against fault in a single component in a parallel network do not hinder the functioning of another part of the circuit.

The detection of a fault in case of a series circuit is difficult, but it is quite easy in parallel circuits.

a single cell undergoes mitosis every five minutes how many cells will result from this cell in 20 minutes

Answers

Answer:

= 16 cells

Explanation:

Mitosis is the stage of cell division in nonsexual cells of eukaryotic organisms (that is, cells that have a nucleus). It takes place in several phases, begins after DNA duplication and ends with the separation of the two daughter cells.

It is a fundamental mechanism that occurs for the first time in the hours following fertilization.

After duplication of the genetic material, during interphase, it condenses and groups to form chromosomes with two genetically identical chromatids: this is the prophase. The nuclear membrane then dislocates, and the centromeres of the chromosomes (the area where the two chromatids of the same chromosome overlap) bind to the microtubules via the kinetochores. Gradually, all the chromosomes are sequestered at the equator of the cell: this is the metaphase.

Then, during anaphase, the chromosomes will split into two chromatids, each of which is pulled towards a pole of the cell. Thus, at each top of the cell, there is a copy of each chromosome. During telophase, the nuclear envelope will begin to reform around the set of chromosomes as the DNA gradually decondensed. The plasma membrane invaginates equatorially under the action of a ring of myosin and actin. Increasingly narrow, the bridge between the cells eventually breaks, and two cells are formed as a result of cytodieresis. Each of them can resume their growth.

Now; having understood what Mitosis is all about.

When a single cell undergoes mitosis every 5 minutes; we have the formation of two daughter cells.

Then in 20 minutes; we will have:

= [tex]2^{20/5}[/tex]

= [tex]2^4[/tex]

= 16 cells

A student mixed several different 12 mm plastic beads together by mistake. Luckily the beads had different densities. One group of beads had a density of 0.6 g/cm3; the other beads had a density of 1.2 g/ cm3. Describe a method the student can use to sort the beads.

Answers

Answer:

The answer is "Each student will get a glass of water and drop the bead into it  but the beads float 0.6 g / cm3 and slip down to 1.2 g / cm3

".

Explanation:

One's masses would've been dissimilar, even though their width and concentrations were also equal. Whenever the type-A mass is m,  then the type-B mass is 2 m. One should measure then, therefore.  

Water has a 1g / cm^3 density. Although Type A is higher than air, Type B is much more compact. it means will float if they place  it in water type-A where type-B sinks.

Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.

What are subatomic particles?

Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.

The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.
