ASAP IMAGE IS ATTACHED THIS IS NOT DIFFICULT
There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.
6a. The mRNA code for each type of amino acid is a
sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)
6b. In the figure, which mRNA codon codes for the amino acid Phe?
Answer:
The mRNA code for each type of amino acid is a sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.

Answer:
The description about population according ecologists is as follows:
Explanation:
Thre are various ecological aspects studied by the ecologist in the ecosystem and one of them is Population ecology. According the ecolgists all member or total individuals of a particular species present in an ecological community is Population.
There are different asppects of the population ecology that helps in the understanding the population such as size of population, growth of population nter and intra- intractions of population. All these aspects are part of population ecology studied by the ecologists.

The decrease in carbon dioxide (CO2) for the leaf was less than the decrease for the stem.
- More oxygen was produced in the stem than in the leaf.
-There was no photosynthesis taking place in the roots.
- The stem was performing photosynthesis at a faster rate than the leaf.

Explanation:
A mutation that could be inherited by offspring would result from-?
Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.
Explanation:
A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.
What is mutation?Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.
As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.
Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.
Thus, the correct option is D.

How does genetic variation help a species survive through an environmental change
Answer:
Look at explanation
Explanation:
Genetic variation helps a species survive through environmental changes because some individuals can adapt to a changing environment. Genetic variation allows more variations within phenotypes.
What is the formula for speed of a wave?
Answer:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known
Explanation:
looked it up
Answer:
v = f λ
v is wave speed
f is frequency of the wave
λ is wavelength

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.

Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make glucose that feed the cell's machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating glucose.
Which level of organization is represented by the skeleton of the snake?
А.organ
B.organism
C.tissue system
D.organ system
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.
