A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
Hope this make sense!
Which of the following actions will provide a negative control for the investigation?
Repeating the experiment at 25°C
Repeating the experiment at 25°C
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of peroxidase
Repeating the experiment using twice the amount of peroxidase
The question is incomplete, the complete question is;
Researchers investigated the influence of environmental pH on the activity of peroxidase, an enzyme that catalyzes the conversion of hydrogen peroxide to water and oxygen gas. In an experiment, the researchers added a hydrogen peroxide solution containing guaiacol to several identical test tubes and adjusted the solution in each test tube to a different pH. The researchers included the guaiacol because it caused the solutions to change color as the reactions proceeded, which the researchers relied on for measuring reaction rates. Finally, the researchers added the same amount of peroxidase to each test tube and measured the rate of each reaction at 23°C. The results of the experiment are represented in Figure 1.
Figure 1. The effect of pH on peroxidase activity
Which of the following actions will provide a negative control for the investigation?
A
Repeating the experiment at 25°C
B
Repeating the experiment using twice the amount of hydrogen peroxide
C
Repeating the experiment using twice the amount of peroxidase
D
Repeating the experiment using heat-denatured peroxidase
Answer:
D
Repeating the experiment using heat-denatured peroxidase
Explanation:
A Negative control is a situation in which a particular reagent added to an experimental set up just as all the other samples is not expected to effect any change in the responding variable.
In this case the independent variable is the pH of the solution while the responding variable is the activity of peroxidase enzyme.
A denatured enzyme is not expected to have any effect on the responding variable. Hence, this is a negative control.
The action that will give a negative control for the investigation is D. Repeating the experiment using heated-denatured peroxide.
A negative control simply means the situation where a reagent that is added to an experimental set up is not expected to have an impact on the responding variable.
It should be noted that repeating the experiment at 25°C will not lead to a negative control for the investigation. On the other hand, the repetition of the experiment using heated-denatured peroxide will lead to a negative control as the responding variable isn't affected.

A heterotroph
is an organism that takes in or consumes other organisms to receive energy; it is also called a consumer.
Explanation:
An autotroph is an organism that uses the energy from the sun or inorganic substances to make its own food; it is also called a producer. A heterotroph is an organism that takes in or consumes other organisms to receive energy; it is also called a consumer.
What are autotrophs and heterotrophs?An autotroph can be referred to as an organism which uses the energy from the Sun or inorganic substances present in the environment to make its own food. These organisms are also called as producers. These organisms produce their own food through the process of photosynthesis.
Heterotrophs are the organisms which takes in or which consumes other organisms for receiving energy or as the food source. These organisms are also called as consumers. Consumers are further divided into different types on the basis of their food such as carnivores, omnivores, etc.

AsUsing the word "niche” in your answer, explain why this species may have a
higher probability of becoming endangered than a species that eats ten species of plants.
In interspecies competition, two species use the same limited resource. Competition has a negative effect on both of the species (-/- interaction).
A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of).
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources).
Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

What is the force of an object if it accelerates 4 m/s2 and has a mass of 10 kg? (F = ma)
A.
0.4 Newtons
B.
2.5 Newtons
C.
40 Newtons
D.
100 Newtons
Answer:
C. 40 Newtons
Explanation:
We are given the equation to calculate force:
Force=mass×accelleration
To find the answer, we just need to plug the given mass and acceleration into the equation. The units of these values are typically kg and m/s^2 when calculating the force in Newtons, which they already are (so we don't need to do any conversion).
Mass=10kg
Acceleration=4 m/s^2
F=ma
F=10×4
F=40 N
Therefore, the force of the object is 40 Newtons.

1. The human population is increasing by about 1.19 percent each year. Assume that the
population is 6.8 billion (6,800,000,000).
How large will the population be in one year?
The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.
Calculation of the population:Since the population is 6.8 billion or 6,800,000,000
And, the increase rate is 1.19% each year
So the population in one year should be
= 1.19% of 6.8 billion
= 8,092,000,000
hence, The population that should be large in one year is 8,092,000,000 when the population should be increased by 1.19 percent.
