cells.
Answer:
Explanation:
When a cell divides, it creates two identical daughter cells that each carry a copy of the original cell's DNA. The name for this process is mitosis, and errors in the process result in incorrect DNA copies. The effects of these errors on the health of the organism range from benign to deadly, depending on their number errors and type. One potential consequence is cancer;
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
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.
What causes cells to have different functions despite having the same DNA?
Answer:
This is on the grounds that the entirety of the cells in our bodies start from a solitary prepared egg. With hardly any exemptions, all cells in an individual's body have a similar DNA and qualities. As cells isolate and develop various qualities are communicated, bringing about various cell types.

Answer:
A set of practices that humans can follow to meet their needs without causing long-term, negative effects on species or ecosystems.
Explanation:
Sustainability means "the ability to be maintained at a certain rate or level." So sustainability is the ability for humans to meet their needs, while also maintaining the ecosystem and different species at the same rate and level.

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.
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

Plants get for photosynthesis from the sun.
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.

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.
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.
