How might it be possible for a child to show a trait that neither of the parents showed?
A person can only show a recessive trait if both of their parents carried at least one copy of each of the recessive allele. The parents do not need to show the trait, as one copy is not enough to reveal it, but they must both carry it.

A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?
Answer:
co dominance
Explanation:
codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.
as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

Bedrock in the area of Binghamton, New York, consists of?
a)plutonic igneous rock
b)sedimentary rock layers
c)faulted and tilted volcanic rock
d)folded metamorphic rock
Answer:
b)sedimentary rock layers
Explanation:
New York is composed of sediments that have metamorphed around 400 to 500 million years ago during the Acadian and Taconic orogenies.
Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers. So, the correct option is B.
What are sedimentary rock layers?The formation of sedimentary rocks involves the accumulation or deposit of mineral and organic particles at the Earth's surface, following by cementation. The mechanisms that lead to the accumulation of these particles are collectively referred to as sedimentation.
Sediment refers to the little particles that make up sedimentary rocks and can be either geological detritus (nitrogen and phosphorus) or biological detritus (organic matter). Sandstone, limestone, and mud are examples of typical sedimentary rocks.
These rocks frequently begin as sediments that are transported by rivers, then are dumped in lakes and oceans. The sediments become dry and cement together to form rock when they are buried. Volcanic ash can be found in tuffaceous sandstones. Bedrock in the area of Binghamton, New York, consists of sedimentary rock layers.
Therefore, the correct option is B.

Which of the following is most affected by natural selection?
Angora rabbits
Merlot grapes
Influenza (The Flu)
Poodles
Answer:
Influenza (The Flu)
Explanation:
Influenza (the flu virus) is a real-life example of natural selection that is most evident during an annual time period when the influenza virus infection peaks. The repeated or cyclical nature of flu outbreaks is caused by the natural selection of the virus for traits that allow it to evade the immune system and replicate, a process that actually results in new distinct strains of influenza virus.

Some adaptations are helpful in one environment, but would be harmful in other environments. Ex) Thick fur, helpful in cold environment, but harmful in hot environments
Answer:
Thin fur is helpful in hot environments, but harmful in cold environments
The statement "Some adaptations are helpful in one environment but would be harmful in other environments. Ex) Thick fur, helpful in cold environments, but harmful in hot environments, is true.
What are harmful adaptations?Because they might alter how the body normally functions, some adaptations can be toxic or damaging to an organism. These are the kinds of maladaptations that can alter a population. They develop as a result of mutations or adjustments to the population's genetic makeup.
An organism adapts when it undergoes changes throughout time, frequently as a result of genetic mutations that happen by chance and are handed down to succeeding generations. Many diverse creatures have structural or behavioral adaptations that are advantageous to them physically.
Therefore, the statement is true.

Tmp/smx has two components that act on different steps in the folic acid biosynthesis pathway and are thus used together. sulfamethoxazole is a structural analog of a compound called paba, competing with it in the enzymatic production of dihydrofolic acid, an intermediate in the synthesis of folic acid. trimethoprim inhibits the step following dihydrofolic acid production and prevents the formation of the biologically active form of folic acid. choose true statements regarding tmp and smx.
Trimethoprim-sulfamethoxazole (TMP-SMX) are a class of antibiotics used in the treatment of bacterial infections due to their inhibitory actions in the folic acid biosynthesis pathway of bacteria.
What is TMP-SMX?Trimethoprim-sulfamethoxazole (TMP-SMX), otherwise known as co-trimoxazole, is a combination of two antimicrobial agents that work synergistically to inhibit the enzyme systems involved in the bacterial synthesis of tetrahydrofolic acid.
They are used in the treatment of urinary tract infections, respiratory tract infections, cholera, etc.
They can be administered intravenously or orally.
Therefore, Trimethoprim-sulfamethoxazole (TMP-SMX) are antibiotics used in the treatment of bacterial infections.
