The term that describes the allele that determines the phenotype of an individual organism when two different copies are present in the genotype is?
A. Recessive
B. Nucleus
C. Dominant
D. Eukaryotic
Answer:
A. Recessive
Explanation:
Only answers A and C can be used to describe an allele, so B and D can't be it. If the allele was dominant, only one copy would be necessary for the phenotype to be expressed (ex. heterzygous green peas are still green, even though they carry a yellow allele). Therefore, since 2 copies are present for this phenotype, it must be recessive.
PLEASE HELP

For this structural characteristic, decide if it is a characteristic of DNA, a characteristic of RNA, a characteristic of both or a characteristic of neither? It contains thymine as a base
Answer:it is a characteristic of DNA
Explanation:
Deoxyribonucleic acid(DNA) is made 5 carbon deoxyribose sugar, phosphate group,Nitrogenous base which include purine and pyrimidine. Purine base compose of Adenine and guanine while pyrimidine base compose of Cytosine and thymine.
In Ribonucleic acid (RNA) we have 5 carbon ribose sugar, phosphate group and nitrogenous bases which are purine and pyrimidine. Purine consist of Adenine and guanine while pyrimidine compose of Cytosine and Uracil where thymine in DNA is replaced by Uracil in RNA. This makes Thymine a components of DNA not RNA.
SOOOOMMMEEEE OONNNEEE PLLLEEEASSSEEE HEEELPPP ME. WITH THE RED PART ON THE TOP RIGHT CONER I PICKED ALANTIC PUFFIN BECUSSE IT LOOKS LIKE THR BARN OWL IT SAY I CHOSSE ..... BECUSEE... NEED HELP WITH THAT NOOOOOO LINKS
Answer:
they do kinda look similar although i would choose the owl, mainly since there a top predator in the birb species, they hunt at night cause they know thats a time where the main preys at, they can take down full turkeys, other birds of prey/raptors, as well as abduct full grown dogs and cats depending on the size of them (that has happened to me lol) they have a long life span, they look like grey aliens in disguise as an animal to be amongst the human race, as well as a lot of alien abduction stories and alien sightings the people report seeing large owls either before or after there iincounter, i can add more reasons to like owls if you want
Explanation:
They also poop out there full preys skeleton so if you ever find owl poop there will most likely be a full skeleton of an animal in there

If the US modifies techniques for timber management, it is expected that US forests will
a. not be able to meet long term timber needs
Incomplete question. The full question read;
If the US modifies techniques for timber management, it is expected that US forests will
a. not be able to meet long term timber needs
b. be able to meet long term timber needs
c. result in deforestation
d. provide increasingly cheaper timber
Answer:
b. be able to meet long term timber needs
Explanation:
Remember, the emphasis here is on the modification of the present techniques for timber management in order to boost productivity.
Hence, we can conclude that since there would be an improvement in production efficiency, the US would be able to meet its long-term timber needs.
Answer:
b.
be able to meet long term timber needs

Which of the following statements is correct?
A. Landfills solved pollution problems caused by waste disposal.
B. Wastewater from cities no longer carries toxic chemicals into waterways.
C. Laws regulating waste disposal have put an end to pollution problems caused by waste.
D. Much of the pollution in our environment is a byproduct of inadequate waste disposal.
Answer:
D
Explanation:
all the others are false
Much of the pollution in our environment is a byproduct of inadequate waste disposal, hence option D is correct.
What are the problems of waste disposal?There are some problems caused by solid waste disposal include: finding suitable landfill locations, groundwater pollution, and soil pollution.
Landfills have not solved pollution problems caused by waste disposal, because it creates soil pollution in the area where waste is disposed of, which decreases the fertility of the soil.
Wastewater from cities carries toxic chemicals into waterways, which is the major cause of water pollution in that area. There are some laws that regulate pollution, but not all the person follows them.
Therefore, waste disposal is the major factor of pollution.

Ferns reproduce by making a huge number of spores. How does this help the ferns survive?
It allows the ferns to absorb moisture from other plants.
It increases the chance of new ferns growing.
It keeps the ferns from drying out in hot weather.
It makes the ferns live shorter life cycles.
Answer: Ferns don't grow very with so with more spores it increases the chances of ferns growing.

Which answer best identifies the difference between the two types of cellular transport? (B.4B) Question 3 options: Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.
Answer:
Active transport uses ATP to move molecules against the concentration gradient.Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradientExplanation:
Transmembrane proteins, among others, are the channel proteins and the carrier proteins, and they are in charge of substances transport into or out of the cell.
Channel proteins are involved in passive transport, and facilitated diffusion is a kind of passive transport. Facilitated diffusion transport hydrophilic molecules that can not freely move through the membrane. Channel proteins carry them from one side to the other of the membrane, following the electrochemical gradient, so they do not need energy to carry in or out substances. Uncharged molecules´ movement depends on concentration gradients, while ions´ movement depends on an electrochemical gradient.Carrier proteins are involved in active transport. Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side to a high concentration side. The used energy comes from ATP (Na-K bomb) or the membrane´s electric potential.
