What are some strategies for selecting a speech topic? How will you know if the topic has focus and is appropriate for your audience?
Answer:
Some of the strategies for selecting a speech topic are:
1. Be clear about the nature of speaking event. This speaks to the following questions:
is it an online event? is it a live event? if it is online, will it be audio-visual or audio-only?
2. The purpose of the speech must be established. This is probably more important than the first strategy. This answers the question of what the objective of the speech is. For example, is it to inform? to motivate? or to elicit cooperation?
When the purpose of a thing is known, it becomes easier to do the right thing.
3. The next most important strategy is to know one's audience.
Why is this important? different audiences react differently to different information and methods of communication. Some of the factors to look out for are gender, beliefs, age, nationality, level of education, ethnicity etc. If one is aware of the common denominators in one's audience, it becomes much easier to select a speech topic.
4. Look out for what is trending. Trending topics make it easier to connect with one's audience. A great speech could be one which addresses a topic that strikes across board emotionally to a broad audience. An example would be National Security and the Role of Law Enforcement Agents.
Cheers!
Consider the cladogram. Which is the best description of the two organisms highlighted in pink? They are separated by two nodes. They share a recent common ancestor. They belong to the same species. They are ancestors of each other.
Hello. You forgot to attach the cladogram. The cladogram is attached below.
Answer:
They share a recent common ancestor.
Explanation:
The cladogram is a diagram widely used to show the relationship between the different taxes that make up the species. Using this diagram it is possible to observe the ancestry and biological evolution of living beings over the years.
Each line in the cadogram represents a living being, or a taxon that gave rise to other lines, that is, it gave rise to other living beings. In this case, in the cladogram below we can see that the two organisms highlighted in pink, have lines that originate from the same line, which shows that these organisms share the same ancestor.
Answer:
They share a recent common ancestor.
Choices:
They are separated by two nodes.
They share a recent common ancestor.
They belong to the same species.
They are ancestors of each other.

Which form of coal has the highest sulfur content?
A) Bituminous coal
B) Subbituminous coal
C) Lignite
D) Anthracite
E) Bituminolignous coal
Answer:
D) Anthracite
Explanation:
0.6 -0.77 weight percent
Lignite is a form of coal has the highest sulfur content.
Coal is ranked based on the degree of carbon contained in the coal. The best coal has the highest amount of carbon and hence it is the cleanest.
Lignite is brownish black and it is also called brown coal. It has the least carbon concentration and the highest sulfur content. It gives out the highest heat.
Anthracite referred to as hard coal is black and lustrous. Anthracite has low in sulfur and high carbon. It is the highest rank of coal.
Lignite is a form of coal has the highest sulfur content.

Intro
The various operations like addition, subtraction, multiplication and division can be used to simplify the exponent algebraic expressions. The given exponential expression can be simplified as 2b⁵/(ac⁵).
What is simplifying exponents?A method which is used to simplify the algebraic expressions involving exponents into a simpler form such that they cannot be further simplified is defined as the simplifying exponents.
The exponent of a number indicate how many times the number is multiplied by itself. We use laws of exponents to simplify the exponent expressions. There are rules in algebra for simplifying exponents with different and same bases that we can use.
On simplifying (4a³b⁶c⁻³) ÷ (2a⁴bc²)
= (4/2) (a³/a⁴) (b⁶/b) (c⁻³/c²)
= 2a³⁻⁴ b⁶⁻¹ c³⁻²
= 2a⁻¹b⁵c⁻⁵
= 2b⁵/(ac⁵)
So the simplified form is 2b⁵/ac⁵.
