In the year 2500, five male space colonists and five female space colonists from Earth settle on an uninhabited Earth like planet in the Andromeda galaxy. The colonists and their off-spring randomly mate for generations. All ten of the original colonists had free earlobes, and two are heterozygous for that trait. The allele for freeear lobes is dominant to the allele for attached ear lobes.
Required:
What is the allele frequency in the founding population?
Answer:
The correct answer would be - 0.1 a, 0.9 A
Explanation:
The initial population of the colonist had free earlobes which are represented by A here as it is dominant and attached is represent by a. purebred dominant would have AA.
Frequency of allele A =
8 pure dominant and 2 heterozygous dominant presents in the population
So, frequency of A allele = 8 x 2 + 2 / 20
= 18/20
= 0.9
As we know
p+q=1;
frequency of allele "a" = 1-p
= 1-0.9
= 0.1

Jessica: Pitch is how high or low a sound is. The pitch depends on vibrations. High pitch sounds have low amounts of vibrations
Rachael: Pitch describes how high or low a sound is. Sounds are caused by vibrations. The more vibrations, the higher the pitch.
Harvey: Pitch is caused by vibrations. The more vibrations, the lower the pitch of the sound.
Derek Pitch is how high or low a sound is. All sounds have mostly the same pitch.
Who has the best description of pitch?
Jessica
O Rachel
O Harvey
O Derek
Answer: Rachel
Explanation:
Pitch indeed refers to the highness of lowness of a sound. We are able to sense pitch based on the frequency of the sound wave with a higher frequency (more vibrations) having a higher pitch and a lower frequency having a lower pitch.
This is why lighter strings on guitars produce a higher pitch because when struck, they vibrate more as opposed to heavier strings. Rachel is therefore correct.

Which of the following is an example of an ecosystem?
A. All of the plants and animals that live in a forest.
B. All of the squirrels that live in a forest
C. All of the living and nonliving things that interact in a forest.
D All of the squirrels that live in a forest, as well as the water, air, and living things the squirrels need to survive.
Answer:
c) all if the living and nonliving things that interact in a forest.
Explanation:
The example of ecosystem is as follows: All of the squirrels that live in a forest, as well as the water, air, and living things the squirrels need to survive.
What is an ecosystem?Ecosystem refers to the interconnectedness of organisms (plants, animals, microbes) with each other and their environment.
Ecosystem can also be described as the relationship between the abiotic and biotic components of the environment.
Therefore, a valid example of an ecosystem is all of the squirrels that live in a forest, as well as the water, air, and living things the squirrels need to survive.

Explanation:
in which case would facilitated diffusion be needed?
A. With large polar molecules moving against the concentration
gradient
B. With very small non polar particles moving down the
concentration gradient.
C. With very small polar particles moving against the
concentration gradient.
D. With large non polar molecules moving down the concentration
gradient.
Answer:
The case in which facilitated diffusion would be needed is in the transport of large non-polar molecules moving down the concentration gradient.
Explanation:
Facilitated diffusion (FD) involves a form of passive transport, that is, it does not require energy and mobilizes substances across the cell membrane in favor of a concentration gradient.
The passive transport mechanism of FD is necessary only in the case of transport of very large molecules or polar molecules that:
Cannot be transported by simple diffusion, due to the selective permeability of the membraneThey follow a concentration gradient, from the place with the highest concentration to the one with the lowest concentration.For FD to occur, it requires the use of a protein, which acts as a carrier of the molecules to be mobilized.
The other options are not correct because:
A and C. Passive transport, as facilited diffusion, implies movement in favor of a concentration gradient.
B and C. Non-polar small or very small molecules can cross the membrane by simple diffusion.
With large non-polar molecules moving down the concentration gradient.

Dr. Thalmus suggested that Tim take a regimen of Human Chorionic Gonadatropin (HCG), which has the same effects as Luteinizing Hormone (LH) Why would he recommend this
Answer:
Tim and his wife are trying to have babies
Explanation:
The hCG or the Human chorionic gonadotropin is the name of a hormone that is for the maternal recognition of pregnancy and is produced by the trophoblast cells which surrounds a growing embryo, and it eventually forms placenta after implantation.
Luteinizing hormone is also known as gonadotropin. This hormones is an important sex hormones for both men and women.
In the context, the doctor advised Tim to take a medical course of hCG that is having the similar effects like the luteinizing hormones as Tim and his wife is planning for babies.
