Answer: D. Thymine is used in replication while uracil is used in transcription.
Explanation:
Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA or messenger RNA.
Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:
Adenine (A)
Guanine (G)
Cytosine (C)
Thymine (T).
Uracil (U) found in RNA
While both contain four nucleotide bases, in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,
Which is an abiotic factor that can be found in a rain forest ecosystem?
A. Air
B. Algae
C. Flowers
D. Animals
Answer:
A. Air
Explanation:
Abiotic factors are things that are not living.
Air can be found in a rain forest ecosystem, as it can be found in all ecosystems, but it is not living.
On the other hand, algae, flowers, and animals are biotic instead of abiotic because they are living things.
So, A is the correct answer.
Study this unusual food chain. What could ‘P’ represent?
a. Any normal insect that eats grains.
b. An insect that can make its own food.
c. A carnivorous plant like the Venus flytrap.
d. There is a mistake - nothing can match 'P'.
The correct option as to what P could represent in the food chain would be option C.
P could be a carnivorous plant such as Venus flytrap because these plants are able to get their food both by harnessing solar energy to photosynthesize and by feeding on flying insects.
On the other hand, P cannot be any normal insect that eats grains or makes its own food because according to the diagram, P also derives energy from the sun. Only plants and some microbes are able to photosynthesize.
Therefore, only a carnivorous plant is able to both photosynthesize and feed on insects for their foods when necessary and hence, can fill the space of P in the food chain.

why are casts, molds, and trace fossils so common?
Answer:
Cast fossils occur when mold fossils are filled in with minerals that harden over time, creating a fossilized replica of the original organism. Water seeps through the rock surrounding the mold fossil, leaving behind minerals which fill the mold. Any mold fossil can potentially form a cast mold.

How do sediments eroded by water become more smooth and round
Answer: Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment causing it to become more round and smooth.
I hope this helps!
Answer:
through friction.
Explanation:
The sediments rub together to become smoother. Sediments that are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round.

A.
The genetic code consists of nucleotides in triplet codes.
B.
There are a few organisms that respond differently to the start and stop signals in the genetic code.
C.
Microorganisms contain codons and anticodons.
D.
Almost all genes in microorganisms, plants, and animals have the same codons.
Answer:
The genetic material's inheritability shows how that the DNA of all creatures, both living and dead, can be traced back to a single point, which is our common ancestral origin of life.

Explain over production and reproduction
Explanation:
Overproduction in Natural SelectionNatural selection occurs in specific populations of organisms because of several factors. It begins with overproduction. Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment. Because of this, competition takes place for limited resources. Individuals have traits that are passed down to offspring. Some of these traits give individuals an advantage when it comes to surviving to reproduce. The organisms with these traits are more likely to live and have offspring who will inherit the helpful traits.
HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.
B: Proteins' tertiary structure is dictated by R group bonds.
C: Proteins have quaternary structure when they are arranged together.
The statement that is not true related to the protein structure is option b. Proteins' tertiary structure is dictated by R group bonds.
What is protein structure?It is classified as the three dimensional shape of the protein.
In the tertiary structure it does contain the single polypeptide chain that we called as the backbone or there more than one protein secondary structures
Also, it should not be dictated by R group bonds.
Therefore, we can conclude that the option b is correct.

Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?
Group of answer choices
3/16
9/16
0/16
1/16
Answer:
The correct answers are -
A. 1) WWTt 2) WWTt 3)WwTt 4)wwTT
B. 1/16
Explanation:
We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.
So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are
1. WWTt by WT and Wt gamets
2. WWTt by WT and Wt
3)WwTt by Wt and wT
4)wwTT by wT and wT
And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16
