Explanation:
Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined and used to determine the actual allele frequencies in the population.
Required:
Is this population in Hardy-Weinberg equilibrium? Calculate the T and t.

Which of the following are sources of low-level radiation?
A)
medical X-rays
B)
nuclear weapons testing
C)
buring of fossil fuels
D)
all of the above
E)
a and c only
Answer:
im pretty sure its E
Explanation:
The sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only, as radiation can be classified into two main types: ionizing radiation and non-ionizing radiation.
What is radiation?Medical X-rays are a type of ionizing radiation used for medical imaging. Although the amount of radiation exposure from a single X-ray is usually very small, frequent exposure to X-rays can increase the risk of cancer. The use of X-rays in medical imaging is carefully monitored to ensure that the benefits outweigh the risks. Ionizing radiation has enough energy to remove tightly bound electrons from atoms, which can cause damage to living tissue and increase the risk of cancer. Medical X-rays and the burning of fossil fuels are sources of ionizing radiation that can produce low-level radiation.
Hence, the sources of low-level radiation are A) medical X-rays and E) the burning of fossil fuels, so the correct answer is E) a and c only.

Answer:
Systems thinking is a powerful approach for understanding the nature of why situations are the way they are, and how to go about improving results. Historical perspective is important in understanding the evolution of a situation and in identifying patterns of behaviors over time.
Explanation:
Which is a cause of chemical weathering
A.gravity
B.acid
C.sunlight
D.wind
Answer:
B. Acid
Explanation:
Acid is the cause of chemical weathering because chemical weathering only occurs when water or whatever mixes with the water is slightly acidic, i.e. salt deposits on the ground mixing with run-off rain water and wearing away at the surrounding environment. Acid rain is also the perfect example of this.

Question 19 options: The answer is "LONG" the rest are muscles.
Cardiac

Long
Smooth
Answer:
Long is not a muscle
Explanation:
the 3 types of muscles are cardia skeletal smooth, have a great day
The answer is "Long." "Long" is not a type of muscle; it seems to be an incorrect option. The correct options for types of muscle are Cardiac, Skeletal, and Smooth.
These are the three main types of muscles found in the human body. Cardiac muscles are found in the heart, skeletal muscles are attached to the skeleton and enable voluntary movement, and smooth muscles are found in various organs and control involuntary movements.
Therefore, "Long" is not a recognized type of muscle and does not fit within the categories of cardiac, skeletal, or smooth muscles.

The feature may interrupt the sides of a composite-cone volcano is fumaroles. Thus, option B is correct.
What is fumaroles?They are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction.
Fumaroles are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction. Water flows in the form of steam continuously through the cracks of a volcano or volcanic surface because its temperature exceeds 100 °C.

compare the hygiene allergies and asthma?
Answer:
According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms. Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.

Why is it NOT correct to say that individuals evolve?
Answer:
individuals grow and develop throughout their life, but evolution is something that happens to a species over generations. evolution takes a long time and is a species adaptation to its environment, such as arms getting longer or extra bones. babies are born with these adaptations throughout generations, it’s not something individuals develop during their lifetime.

List three types of blood cells and indicate what they do to help your body maintain homeostasis
Answer:
Both cells present in the blood come from the marrow of the bone. They start their lives as stem cells and develop into three main cell types: RBCs, WBCs, and platelets.
RBCs- The red blood cells supply the cells with oxygen and extract carbon dioxide. ... In controlling the processes of the body and preserving homeostasis, blood plays an important role. It carries out many functions within the body, including: supplying tissues with oxygen (bound to hemoglobin carried in red cells)

If the offspring of the cross showed ccdominance, what would the eyes of the offsping look like?
Answer.. the offspring would have one circle eye and one star eye.
Answer:
That is what I would choose
Explanation:
When two different phenotypes of an organism are crossed, a third phenotype is created in which both of the parental traits are present. This is known as codominance.
What are the results of codominance cross?The concept of codominance states that although both phenotypes are dominant, they cannot coexist. Codominance would result in patches rather than merging, with areas of prominent white expression and areas of dominant red expression.
The statements made about codominance are all accurate. The full expression of both alleles is present.
The distinct results of both alleles are present in the heterozygous phenotype. A multiple-allele characteristic has (less than / only / more than) two alleles in the corresponding gene.
Therefore, The offspring would have one circle eye and one-star eye.
