Which statement is evidence that the components of the genetic code are common to all organisms?
A. All animals have the same four nitrogenous bases in common with each other.
B. All eukaryotes have the same four nitrogenous bases in common with each other.
C. All living organisms have the same four nitrogenous bases in common with each other.
D. All prokaryotes have the same four nitrogenous bases in common with each other.
Answer:
C. All living organisms have the same four nitrogenous bases in common with each other.
Explanation:
Because all living organisms have the same 4 nitrogenous bases in common with each other but different sequences.
The sequential series of nucleotide triplets that are positioned in the A site of the ribosome during translation. A. Primary structure B. Exons C. Promoter D. Reading frame
Answer:
The correct answer is D.
Explanation:
Reading frame is a sequence of codons determined by nucleotides that are read in groups of three from a specific translation start codon, that is, it is a linear sequence of codons or triplets in a nucleic acid. It is one of three possible reading alternatives of a nucleotide sequence of a series of triplets, this means that, in a double-stranded DNA molecule, there are 6 possible directions in which reading frames can be opened; three in the forward direction and three in reverse.
1.Name one living (biotic) and non- living (abiotic) means of seed dispersal
that is involved in helping plants with seed dispersal.
2. What is the advantage for a plant to produce fruit that are delicious to
animals?
Answer:
1.abiotic- air and biotic-birds
2.producing delicious and good fruits for animals protect and help them to spread. delicious food attract animals like birds and other animals who are feed on them. when they eat the fruits and the seeds pass by unharmed. these way the seed dispersal occur of a plants.
Seed dispersal is a movement transport and spread of the seeds away from the parent plants. As plants have very limited mobility and transportation also includes some of the abiotic factors.
Winds, waves, gravity, and many more abiotic form of seed seed dispersal have been found. The biotic forms of seed dispersal include man, animals and birds. The more delicious is the plant the more is the chance of seed dispersal and hence is an added advantage to the plants. The seeds remain unharmed and many animals like to feed on them.Learn more about the living (biotic) and non-living (abiotic) means of seed dispersal.

T/F Osmosis and diffusion are both examples of passive transport.
A.True
B.False
Both osmosis and diffusion are passive transport processes, meaning that no additional energy is needed for them to take place. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration.
The given statement "Osmosis and diffusion are both examples of passive transport" is True.
Passive membrane transfer methods are the most direct. Passive transport is a phenomena that happens spontaneously and doesn't require the cell to use energy to move. Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration. A concentration gradient is a difference in the concentration of one substance throughout a physical region.Transport that is done passively is called diffusion. Until the concentration is the same across the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration.Based on the gradient of water concentration across the membrane, osmosis is the mechanism by which water diffuses through a semipermeable membrane. Osmosis moves just water across a membrane, and the barrier restricts the diffusion of solutes in the water, whereas diffusion distributes material across membranes and into cells.Learn more about the passive transport with the help of the given link:

5. Some advantages of sexual reproduction include: (select all that apply) *
a.genetic variation
b.improves chances of adapting to the envionment
c.helps species survive catastrophes
d.Certian genes work beter than other
Some advantages of the sexual reproduction include genetic variation. Genetic variation results into changes in the genetic material (DNA). Thus, the correct option is A.
What is Genetic variation?Genetic variation is the difference in the DNA (deoxyribonucleic acid) among individuals or the difference between different populations. The multiple sources of genetic variation include mutations and genetic recombination. Mutation is the changes in the genetic material of an organism which are the ultimate sources of genetic variation, however other mechanisms, such as genetic drift, contribute to it, as well.
Genetic diversity is important because it gives the species a better chance of survival through variations. However, the genetic diversity can be lost from the species when the populations get smaller and isolated from each other, which decreases a species' ability to adapt and survive better in the condition.
Therefore, the correct option is A.

if a nutrient were in short supply in an ecosystem, how might it effect an organism
Answer:
Its leads to a deficiency
Explanation:
If a nutrient is in short supply in an ecosystem, it will lead to a deficiency of such nutrient in organisms that are in need of the nutrient.
Such a deficiency can lead to diseases in the ecosystem. If organisms that requires the nutrient cannot find an alternative, it will seriously affect their well being. Such deficiency often lead to very dire consequences for the balance of the ecosystem at large.this is the pic
it's science btw

Which mutation below would result in the greatest amount of change in the proteins that code for a particular trait?
(Please help I will reward)
A. inserting three nucleotides
B. deleting three nucleotides
C. deleting one codon
D. deleting two nucleotides
Answer:
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations. Some mutations, however, can have a huge affect on coding for amino acids, which can in turn affect what proteins are produced, which can have a profound effect on cellular and organismal function.
