What is the name of a specific type of model that shows how animals diverge during evolution?(1 point)
taxonomy
hierarchy
diagram
cladogram
Answer:
Cladogram.
Explanation:
A cladogram is a diagram used in cladistics to show relations among organisms. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. In biology, taxonomy is the scientific study of naming, defining and classifying groups of biological organisms based on shared characteristics. Taxonomy would not be based on genetic diversion during evolution, it only describes similar characteristics amongst animals.
I also chose taxonomy on the test and it was wrong. The right answer said cladogram.
A specific type of model that shows how animals diverge during evolution is Cladogram. So, the correct option is D.
What do you mean by Evolution?Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms.
A cladogram is a diagram that shows the evolutionary relationships of several clades. A clade is a group of organisms, which contains both an ancestral species and its descendants. The common ancestor appears at the root of the cladogram.
Therefore, A specific type of model that shows how animals diverge during evolution is Cladogram.

How would this disease affect blood pressure and blood flow?
Answer:
In atherosclerosis, plaque can grow to create a blood vessel stenosis. This stops the flow of blood upstream of the obstruction and increases the vascular resistance it causes an increase in blood pressure
Just as slow-moving water loses sediment, fast-moving water can pick up new sediment to carry. Which part of the river
bend will experience the greatest amount of new erosion? How will this erosion affect the shape of the river?
Answer:
The part of a riverbend that will experience the most erosion is the inside corner, this is because the water will be hitting it on two sides, the erosion will likely curve the inside corner more.
The water flowing at the maximum velocity and with the greatest ability to erode is on the outside of the curve, rivers that meander erode in both directions.
What factors affect the river?Cut bank erosion occurs when the edge of a stream channel bends, and it increases the loop of the meander, water that moves more quickly has greater kinetic energy.
It can therefore transport bigger particles, more articles may also be carried by it, and bigger and larger particles can be carried by a stream as it moves more quickly. The capacity of a stream increases with the size of the particles it can transport.
Therefore, a stream will have a quicker velocity if it has a steep slope or gradient, which implies it may transport heavier items in suspension.

by always pointing north. Which part of Earth is responsible for creating
its magnetic field?
A. Cilist
B. inner core
C. mantle
D. outer core
Answer
Outer Core
Because of the weight of the melting moving metal creates energy
Our planet is shielded from cosmic radiation and charged particles from our Sun by the magnetic field, which is created by the motion of molten iron in the Earth's core. It also offers the framework for compass navigation. Thus, option D is correct.
What role of outer core of earth in magnetic field?Radiative heating and chemical differentiation have caused the Earth's outer core to be in a state of turbulent convection.
The convective kinetic energy is transformed into electrical and magnetic energy through a mechanism that is somewhat similar to a naturally occurring electrical generator.
The magnetic field is not produced by the earth's core, since metals lose their magnetic characteristics at high temperatures.
Therefore, Because of the weight of the melting, moving metal creates energy.

what is dna ? and what is the purpose of dna
Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Explanation:
-Eijiro <3
First, it has to be able to make copies of itself because you're making new cells all the time and your cells have to have a copy of your DNA so it has to do what we call replication.
It also has to store all the information about your body as far as your body chemistry, your proteins, your amino acids, and all the things that make you.
One more very important job of DNA is that it's responsible for this process called protein synthesis which is the process in which cells make proteins. So every piece of your body from your fingernails, your eyeballs, and many other things are made up of proteins, proteins are the building blocks of you and the DNA determines the shape and function of your proteins. You think of DNA as a set of instructions on how to make the proteins that make you.

What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?
Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

You will build a simulation of a population using the same elements as the simulation pictured here and show how
the traits in this population change in years 5 and 10.
- Trait A
- Trait B
- Trait
1 circle = 50 organisms
Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip
leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each
trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.
According to the concepts of percentage and proportions, we can make the simulation with 20 circles, each of them representing 125 plants. Traits A = 10 circles. Trait B = 5 circles. Trait C = 5 circles.
To solve this problem, we need to know two concepts, percentage and proportion.
What is a percentage?A percentage can be defined as a fraction or a part of 100. It is denominated as percent (symbol %).
100 refers to the number of parts into which the unit has been divided.
So, X% means that for every 100 parts, X parts are of our interest. Or, that we are interested in X fraction from a total of 100 parts.
What is a proportion?A proportion is the equal relationship between two determined ratios or quantities.
In the exposed example we need to represent this population of 2500 plants with circles.
We know that,
Each circle represents 125 plants50% of the population have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves .So here, our unit is the population. We can say that our population of 2500 plants is composed by 100 subunits or parts.
2500 plants ------------ 100 parts
So now we will calculate how many plants are represented by the 50% and 25% of the population.
If 100% of the population equals 2500 plants, how many plants are 50% of the population and 25% of the population.
100% -------------------- 2500 plants
50% -------------------- X = (50% x 2500 plants) / 100% = 1250 plants.
25% ---------------------X = (25% x 2500 plants) / 100% = 625 plants
Now we know that from the total of 2500 (100%) plants,
1250 (50%) have medium-tip leaves, 625 (25%) have wide-tip leaves, and 625 (25%) have drip-tip leaves.Finally, we need to calculate how many circles represent these numbers. So, we know that 1 circle equals 125 plants. The question is, how many circles represent 2500, 1250 and 625 plants.
125 plants ----------------- 1 circle
2500 plants -------------X = (1 circle x 2500 plants) / 125 plants= 20 circles.
1250 plants --------------X = (1 circle x 1250 plants) / 125 plants = 10 circles.
625 plants ---------------X = (1 circle x 625 plants) / 125 plants = 5 circles.
So, our simulation must have 20 circles, from which
10 circles represent medium-tip leaved plants (Trait A), 5 circles represent wide-tip leaved plants (Trait B), and the remaining 5 circles represent drip-tip leaved plants (Trait C).In the attached files you will find the image.
