Answer:
Hi, there your answer is D. Have one group live with a much stronger predator.
Explanation:
Having one group live with a much stronger predator will most likely increase the chances of speciation.
What is speciation?It is a process by which a new species of an organism is created.It occurs due to evolution.It occurs when a portion of population gets separated from the original population and evolves different characters that are heritable.Will speciation occur if :one group breeds twice as often as the other? No, because no selective force is acting on it.both groups are in identical ecosystem? No, since no reason for adapting and evolving a new character will be there.both groups interbreed? No, there is no competition, no struggle for existence and hence no evolution occurs.one group lives with a strong predator? Yes, since they will evolve evasive mechanisms and characters.To learn more about species, evolution, and predator here,

What are valence electrons?
A. the atomic mass
B. the atomic number
C. all of the electrons in an atom
D. electrons in the outermost energy level
Answer:
D
Explanation:
The simple answer is the electrons in the outermost energy level.
Hydrogen has 1 electron in the outermost energy level.
Magnesium has 2 so this tells you that magnesium has a charge of 2
Oxygen has 6 oxygen has a charge of - 2
Fluorine has 7
For most elements, the electrons in the most outer ring determine the valence of the element.
Notice that the non metals work differently than the metals. Mg may have a charge of 2 and that is the number of electrons in the valence right.
Oxygen is a non metal it has a charge of - 2. It gets 6 electrons by subtracting the number of its charge from 8.
Answer:
D. electrons in the outermost energy level
Explanation:
The valence electrons are the electrons in the outermost energy level.

do you think there is an aesthetic value that could be attached to the hides of the nguni cattle after slaughtering ?
Answer:
The correct answer is - yes, these hides are used as aesthetic value.
Explanation:
Nguni hides are the secondary products after slaughtering the Nguni cattle farmed in South Africa. These skins or hides are used to make many aesthetic values and beauty items such as floor rugs. These hides are not only famous for their natural beauty but also due to their incredibly hard-wearing and very easy to clean.
Other than Floor rugs these are also used as furniture in rich houses and lodges. These hides are used to make shoes, leather jackets, car leather, and many more.

The variable h represents the number of hours spent doing yard work and the variable d represents the amount of money earned how many hours spent doing yard work and the variable d represents the amount of money earned how many hours in all will it take Whitney to earn 15$
Answer:
[tex]4\frac{1}{11}[/tex] hours
Explanation:
Given
See attachment for graph
First, we determine the equation of the graph.
Pick any two points from the graph
[tex](h_1,d_1) =(18,168)[/tex]
[tex](h_2,d_2) =(36,366)[/tex]
Calculate the slope (m)
[tex]m = \frac{d_2 - d_1}{h_2 -h_1}[/tex]
This gives:
[tex]m = \frac{366 - 168}{36 -18}[/tex]
[tex]m = \frac{198}{18}[/tex]
[tex]m = 11[/tex]
The equation is then calculated as:
[tex]d = m(h - h_1) + d_1[/tex]
This gives:
[tex]d = 11(h - 18) + 168[/tex]
Open bracket
[tex]d = 11h - 198 + 168[/tex]
[tex]d = 11h-30[/tex]
So, the number of hours to earn $15 is:
[tex]d = 11h-30[/tex]
[tex]15 = 11h -30[/tex]
Collect like terms
[tex]11h = 15 + 30[/tex]
[tex]11h = 45[/tex]
Solve for h
[tex]h = \frac{45}{11}[/tex]
[tex]h = 4\frac{1}{11}[/tex]
Why did Gregor Mendel choose to use purebred plants in his experiments?
A They reproduce sexually.
B They exhibit only one form of a trait.
C They have a variety of traits.
D They reproduce asexually.
Answer:
B
Explanation:
Gregor Mendel chooses to use purebred plants in his experiments because they exhibit only one form of a trait. The correct option is B.
What is Mendel's experiment?Mendel altered pure pea plant lineages. First-generation hybrids (F1) displayed dominant qualities like purple flower color while hiding recessive traits like white bloom color.
But in second-generation (F2) pea plants, recessive characteristics returned in a 3:1 ratio (dominant to recessive). Every pea plant has both male and female reproductive organs, and they all typically procreate by self-pollinating.
This was crucial to make sure that there were no other factors influencing the result of the cross when he crossed two plants with different features.
Therefore, the correct option is B, They exhibit only one form of a trait.

4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous
Answer:
B
Explanation:
The correct option would be B
The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.
Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.
Slow and dangerous really have nothing synonymous with unchecked growth.
The correct option is, therefore, B.

In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?
Answer:
1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
2.
a. A semipermeable membrane allows some substances to pass through it.
b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
3.
a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
4.
a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
5.
a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Explanation:
When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.
In isotonic solution the concentration of solutes on side remain same .There is no net gain or less of water in isotonic solution.What will be the direction of water flow in isotonic solution?The water will flow freely across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.To know more about isotonic solution here

picturing the saguaro cactus. Saguaros are known for their long, tall branches that look like
arms. These branches don't start to grow until the cactus is 50 to 70 years old. The folds
along the saguaro's stem and branches are called pleats. What are they for? These pleats
store water for the cactus, which is important in the hot, dry desert. A desert plant's spikes

How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?
Answer:
The correct answer is - cells are the basic unit of life.
Explanation:
As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.
Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.
