Humans vary in their ability to taste the bitter chemical compound phenylthiocarbamide ( PTC ). The taster phenotype is dominant to the non-taster phenotype. Researchers tested the PTC taster phenotype of individuals from an isolated population. In the sample, 780 individuals were able to taste PTC and 70 individuals were not able to taste PTC .Assuming the population is in Hardy-Weinberg equilibrium, what is the frequency of the non-taster allele
Answer:
The frequency of the recessive allele, t is f(t) = q = 0.29.

Mountain peak termed as Pyramidal peak is formed by the movement of multiple glaciers. When glacier starts moving from a central point thereby causing erosion of consolidated landmass to form angular and sharp mountain peak.
I NEED HELP PLEASE!! There are two forms of PKD- autosomal Dominant and
autosomal recessive. Since
Aditya has the dominant form,
if he marries a woman with no family history of PKD, what
are the chances their children will inherit the gene? Show
a punnett square to illustrate your answer
Answer:
Highly likely
Explanation:
ADPKD-AUTOSOMAL DOMINANT POLYCYSTIC KIDNEY DISEASE:-here aditya is affected with ADPKD,and if he marries a women with nofamily history of such disease ,in autosomal dominant PKD,people of this condition are born with one mutated copy of PKD1 OR PKD2 GENES and there are 90% chances that from one affected person with this disease will pass down to the progeny(next generation) and both male and females are equally affected. As for the punnett square, I don't remember those at all, I'm sorry :(
If Aditya has the autosomal dominant form of PKD, he must have inherited at least one copy of the PKD gene from one of his parents. Therefore, Aditya's genotype is either heterozygous (PKD/Pkd) or homozygous dominant (PKD/PKD).
What is PKD?PKD stands for polycystic kidney disease, which is a genetic disorder that causes multiple cysts to develop in the kidneys. There are two types of PKD: autosomal dominant PKD (ADPKD) and autosomal recessive PKD (ARPKD).
If Aditya marries a woman with no family history of PKD, she is most likely homozygous recessive (pkd/pkd).
Using a Punnett square, we can determine the probability of their children inheriting the PKD gene:
PKD Pkd
pkd Ppkd Ppkd
pkd Ppkd Ppkd
Each box represents a possible offspring genotype, with the probability of each genotype indicated in the box. From this Punnett square, we can see that:
50% of their children will inherit one copy of the PKD gene (heterozygous, Pkd/pkd)
50% of their children will inherit two copies of the normal gene (homozygous recessive, pkd/pkd)
Therefore, there is a 50% chance that their children will inherit the PKD gene.

How does a genetic mutation occur?
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

A. electrons
B. isotopes
C. molecules
D. radiation

Answer:
Isotopes
Explanation:
If two atoms have different numbers of protons, they are different elements. However, if two atoms have the same number of protons, but different numbers of neutrons we refer to them as isotopes. Two terms we use to identify nuclides (isotopes) are atomic number and mass number.
What is the volume of 2.7 moles of N2 at STP?
Answer:
60.48L
Explanation:
By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.
Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:
2.7*22.4L
=60.48L

Do all please thank you. If not some is ok.
Answer:
1. Increases
2. Decreases
3. Increases
4. Decreases
5. Increases
6. Increases
Explanation:
Raising air temperature increases temperature of our body while on the other hand, if the air temperature decreases the temperature of our body also decreases because high air temperature heats up our skin surface and low air temperature cools down our skin surface which ultimately increases or decreases the internal body temperature. Adding clothing increases body temperature due to capturing of heat produced by our body. Sweating cools down our body temperature because the water takes the internal heat with itself to the outside. In shivering, the body produced heat so the body temperature increases. Exercising also produces heat inside our body which increases the body temperature.

Explanation:
On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences. Which type of reproductive isolation operates to keep the mosquitofish isolated, even when fish from different ponds are reunited in the same body of water
Answer:
The correct answer is - Behavioral isolation.
Explanation:
In the question, it is given that the mosquitofish of different habitat shows different behavior as per the availability of predators in the particular habitat. For instance, some mosquitofish can swim continuously for a long time in fewer predators area whereas predator-rich ponds have mosquitofish that can swim in short, fast bursts.
It is evident that they diverged from common species that isolated in different regions, their behavior got changed according to the presence of predators. Thus, the isolation is here, behavioral isolation.

If a dog starts to put its paw down on a sharp stone, the tough skin skin protects underlying structures from damage. Additionally, touch receptors in the skin send sensory signals to the spinal cord. The spinal cord then sends a signal to the muscles to lift the paw rather than continuing to press down. In this scenario, the dog may experience discomfort but avoid injury.
What two body systems are being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw?
A.
integumentary and nervous systems
B.
circulatory and nervous systems
C.
circulatory and lymphatic systems
D.
integumentary and lymphatic systems
PLZZ HELP QUICKKK
The two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.
What is the organ system?The dog's response to the sharp stone involves the coordinated action of two body systems: the integumentary system and the nervous system. The integumentary system consists of the skin and its associated structures, including hair, nails, and glands. The skin acts as a protective barrier between the external environment and the underlying tissues, and it has specialized structures, such as tough, keratinized layers in the paw pads, that can withstand pressure and protect the sensitive tissues underneath.
Hence, the two body systems being used to protect the structures beneath the dog's skin and signal the muscles to lift the paw are the integumentary and nervous systems, which are in option A.

Sperm cells swim through liquid. Explain how a sperm cell is adapted to reduce friction as it swims.
Answer:
Long tail and narrow head.
Explanation:
A sperm cell is adapted to reduce friction as it swims by having long head, narrow tail and enzymes. These features of sperm provides ability to swim straight to the egg cell. Long tail helps the sperm cell to swim towards the egg cell, narrow head of sperm cell make the sperm cell for faster swimming towards the egg cell and enzymes present in the head of the sperm helps break through the egg cell membrane so we can say that the long tail and narrow head of sperm cells helps in faster swimming.
