A recessive trait is observed when an organism has 2 recessive genetic factor
Answer: Option C
<u>Explanation:</u>
According to the Mendel’s law of inheritance there are two traits. Dominant and recessive. Usually the recessive are submissive genes which cannot express their characteristics. The dominant trait are the ones which expresses the characteristics.
Two copies of recessive allele are required for the recessive trait to be produced. The recessive trait will be expressed by each parent contributing one allele towards the offspring.

<h3><u>Similarity and differences of carbon cycle in the ocean as on land:</u></h3>
- The Carbon Cycle is a biogeochemical cycle by which Carbon circulates around the planet.
- Carbon Cycle just like other cycles compromises of sequence of events that are essential to make earth capable of sustaining life.
- In land carbon is mostly circulated through photosynthesis and stored in living as well as non-living organisms.
- In oceans carbon is absorbed and dissolved into the water and get used by animals and plants.
- Ocean is like a giant sponge that soaks up more carbon than it gives.
- Like on land photosynthesis too occur in oceans and get incorporated into marine and terrestrial organisms as organic matter.
Answer:
Turtle
Explanation:
I would think a turtle because of its shell and bones. The shell or bones could leave an imprint in mud that could turn into a fossil or the bones/shell itself could become a fossil. (Because what do they find? dinosaur bones) A tarantula doesn't have bones, is much smaller, and I would think would disappear quickly once it dies.
Answer:
The base adenine pairs with thymine, and the base cytosine pairs with guanine.
Explanation:
From Chargaff's discovery, which was that the DNA of any given species contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine, we can deduce that if there is an equal amount of two bases in DNA, those two bases must pair together. From this information, we can then go on to say that since there are equal amounts of adenine and thymine, they pair together, and since there are equal amounts of cytosine and guanine, they also pair together.
