Given the choice of 4 bases and the number of bases needed to make up a codon, how many possible codons are there? 16 23 64 128

Answers

Answer:

64

Explanation:

A codon is a group of three nucleotide sequence in a mRNA that specifies a particular amino acid acid. There are only four nucleotides composed of the four nitrogenous bases viz: Adenine, Guanine, Cytosine and Thymine/Uracil.

A codon is composed of only three of these nucleotide bases at a time. Hence, considering the number of nucleotide bases that can make up one codon and the 4 nucleotide bases, there can only be 4^3 = 64 combinations of the four nucleotides. This means that there are 64 possible codons.

Parents that are heterozygous for having freckles (dominant) are crossed.
What represents the ratio of their offspring? Draw a Punnett square and show your work.

Answers

Answer:

Phenotypic ratio - 3 Freckes : 1 No freckles

Explanation:

This question represents a monohybrid cross i.e. involving a single gene coding for possession or not of freckles. The allele for possession of freckles (F) is dominant over the allele for no freckles (f).

In a cross between two HETEROZYGOUS parents i.e. Ff × Ff, each parent will produce gametes with alleles F and f respectively. Using a punnet square (see attached image), four possible offsprings will be produced with genotypes: FF, Ff, Ff and ff.

Based on this genotypes, the phenotypic ratio of the offsprings will be 3:1 where 3 offsprings will possess freckles and 1 will have no freckles.

Which best explains how gravity contributes to the formation of layers in protoplanets? Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials. Gravity causes materials to undergo radioactive decay, which produces heat and leads to the melting, sinking, and rising of materials. Gravity absorbs heat, which cools materials and causes them to sink and rise. Gravity releases heat into space, which cools materials and causes them to sink and rise.

Answers

Answer:

A

Explanation:

The sentence that best explains how gravity contributes to the formation of layers in protoplanets is ; (  A ) Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials

  Gravity is the force that attracts bodies with masses towards each other. bodies with larger masses posses greater forces of gravity.  therefore

from the options gravity attracts materials and causes compaction which produces heat and leads to the melting, sinking and rising of materials.

Hence we can conclude that Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials

a. Two masses are moved further apart
b. Two masses are moved closer together

Answers

Answer:

a. When two masses are moved further apart from each other, the gravitational force between them will be weaker. They will not have a large effect on each other.

b. However, when two masses are moved closer together, the gravitational force between them will grow stronger (a prime example of this is the Sun's gravitational force on the Earth). The larger the mass is, the higher effect it will have on other bodies of mass.

When two masses are moved further apart the gravitational force will become weak.

Plants get for photosynthesis from the sun.

Answers

Answer:

Plants gain food from the sun by Photosynthesis,

Explanation:

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct

Answer:

Light energy

Explanation:

Photosynthesis is a process that certain organisms called autotrophs, undergo to make their own food. Autotrophs are also called producers. Some examples of autotrophs/producers are plants and algae.

The photosynthesis equation is

carbon dioxide+water+light energy —> glucose+ oxygen

Carbon dioxide, water and light energy from the sun are turned into glucose (the food for the organism) and oxygen (waste product).

The sun provides the plant with light energy for photosynthesis. Therefore, the answer is light energy.

So, Chuck did what any motivated teenager would do to earn money: lots and lots of work. He mowed lawns and raked leaves. He did extra chores and dug in the couch cushions for change. He collected and returned cans and bottles. After about a month of working and scrounging harder than he ever had, Chuck earned a little over $200, but the money was not coming quickly enough. Chuck was discussing his problem with one of his friends on the bus when an older kid named Jim overheard him. "Hey, Chucky," Jim said, "my uncle works at the video game store and he can get any video game system for half off. I can help you get your Game Box 9000." Chuck was so excited about getting the new Game Box that he didn't think twice. "Wow, half off? Then I can afford it!" Chuck was excited! The next day. he gave Jim his money. The following day he hoped to receive the Game Box, but Jim didn't bring it. "Yeah, I'm not going to see him until this weekend," Jim replied. Chuck remembered Jim promising him something else, but he was so happy to get such a great deal on the game console that he didn't want to push him. "Ok, great. Next week then." The week passed by very slowly for Chuck. He was so happy to see Jim the next week. He ran up to him with a big smile, but Jim didn't look happy. "Did you get it?" Chuck asked. Jim replied slowly, "Uh, yeah, I was going to get it, but I got robbed. So, your money's gone. I'm sorry." Chuck couldn't believe it. A whole month of saving down the drain.
