Which question would be asked in a dichotomous key?
A. How long are the insect's antennae?
B. Are the insect's antennae longer than its head?
C. Are the insect's antennae long or short?
D. How does the insect use its antennae?
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The statement B is correct. Are the insect’s antennae longer than its head?
What do you mean by dichotomous keys?A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.
Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.
Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

Cells in the body use oxygen
for cellular respiration. Which is the result of cellular respiration?
ATP is produced, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is released.
ATP is consumed, and carbon dioxide (CO2) is absorbed.
ATP is produced, and carbon dioxide (CO) is absorbed.
Answer:
A
Explanation:
Cellular respiration is done in the mitochondria, the powerhouse of the cell. Their job is to create ATP, and that eliminates B and C. Carbon dioxide is created as waste, then its released that is why we breathe OUT CO2

Why is an overabundance of nutrients harmful to a water supply?
A.
It decreases the number and types of aquatic plants.
B.
It kills all aquatic plants.
C.
It sterilizes water.
D.
It causes excessive aquatic plant growth.
Answer:
d
Explanation:
It leads to a process called as eutrophication in which the aquatic plants grow regularly over the water surface and the living beings living inside the water gets diminished because of the lack of nutrients and the various substances required for the growth.
What is water sterilization ?It is the process in which the harmful substances and contaminants are removed outside the water source such that the water can be removed out from water resources such that they can be made appropriate for drinking.
An overabundance of various nutrient primarily nitrogen along with phosphorus in water begins a process known as eutrophication. The process hammers the growth of other lives present on the sources.
Algae feed on nutrients, growing, spreading and turning out the water green. Algae blooms smells bad, blocks sunlight and even releases out chemicals in certain cases.

Which of the following is the correct equation for photosynthesis?
a.) CO2 + light + H2O --> O2 + Sugar
b.) CO2 + sugar + H2O --> O2 + light
c.) O2 + light + H2O --> CO2 + Sugar
d.) CO2 + O2 + H2O --> Light+ Sugar
Answer: a
Explanation: light is a energy sourse for the photosintesis and sugar is glucose wich is the food formd at the end of phothosintesis like oxigen..(etc..)....
The answer option with the correct equation for photosynthesis is: A. [tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Photosynthesis can be defined as a biological and chemical process through which living organisms such as green plants (autotrophs), transform light energy (sunlight) into chemical energy.
The correct equation for photosynthesis is given by this chemical equation:
[tex]CO_2 + light + H_2O --> O_2 + Sugar[/tex]
Hence, the necessary input for the process of photosynthesis to take place include the following:
Water ([tex]H_2O[/tex]).Sunlight (light energy).Carbon dioxide ([tex]CO_2[/tex]).
In conclusion, oxygen and sugar are end products (output) of photosynthesis rather being an input.

Explanation:
Two students fertilize a pair of pea plants. One plant is Rr, and the other is rr. The offspring produced by
these two plants all had the dominant trait. The Punnett square showed that there was a 50 percent
chance of the offspring carrying rr genes. So, the student assumes that he made an error in determining
W the genetic makeup of the plants. Do you think the student made an error, or is there another
explanation?
No, even though it was only a 50% chance of being Rr, it still could have been that both plants got Rr, cause as long as it's greater than a 0% chance it can happen.
I hope that helps and makes sense!

This woman is likely to be hypothyroid.
Explanation:
The woman has symptoms that may be linked to hypothyroidism, which occurs when the thyroid produces little hormone
thyroid. This disease is more common in women than in men and can be very debilitating if not properly cared for.
The doctor who will assist the woman shown in the question above, should ask questions about what she is feeling and see if she has low immunity, weight gain (in addition to fluid retention), feeling cold, mental depression, menstrual irregularities and constipation .
Finally, the doctor must order a blood test to see if the levels of thyroid stimulating hormone (TSH) and thyroid hormone (T4) are adequate and thus to confirm or not the disease.

Based on the pedigree that is shown above, how to describe Fred?
Answer:
The given pedigree analysis shows sex-linked trait where the female work as a carrier and have X linked recessive gene that is [tex]X^{h}[/tex] and the male is normal.
So, Fred will be a male with [tex]X^{h}[/tex][tex]Y[/tex] gene and Fred will be affected with X linked disease which is carried by female.
If, [tex]X^{h}[/tex] gene in the female (Ann) act as a carrier of hemophilia and the male (John) is normal, then Fred will be a male affected with hemophilia (sex linked disease).
Hence, Fred will be affected male with [tex]X^{h}[/tex][tex]Y[/tex] genotype.
