Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
Answer:
look at the explanation
Explanation:
In frameshift mutations, the addition or deletion of 1,2 or 4 nucleotides occurs, which changes the ribosome reading frame. In single-nucleotide substitution, only one is substituted, as the name implies. A single substation is when one of our DNA bases is replaced with another and changes one amino acid. In Frame-shift, mutations usually have more significant effects on the final proteins. Frame shifts can affect the entire chain of proteins.

if a cell at metaphase of mitosis contains 32 sister chromatids, how many chromosomes will be present in a g1 cell?
Answer:
16
Explanation:
because we are divid 32/2
If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.
During interphase chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes).
In G1, each chromosome is a single chromatid.At the G1 stage, the cell would have 16 chromosomes.Each chromosome has a single chromatid for a total of 16 chromatids in g1 cells.in metaphase sister chromatids are present and the number of chromosomes is 2n.Thus, If a cell at metaphase of mitosis contains 32 sister chromatids, chromosomes will be present in a g1 cell - 16 chromosomes.

True or False: Biodiversity makes living things resilient.
The statement "Biodiversity makes living things resilient" is absolutely false.
What is Biodiversity?Biodiversity may be defined as the sum total of all the varieties of living organisms present on the surface of the earth. This huge biodiversity makes the environment which is good and healthy for the life of each organism.
Biodiversity never plays a role in the resilience of living things. As it only deals with the presence or existence of the number of living forms on the surface of the earth. But yes, it is true that each organism delivers some flexibility to the ecosystem. For example, the presence of bacteria and some other microorganisms act as decomposers which decompose dead and organic remains.
Therefore, the statement "Biodiversity makes living things resilient" is absolutely false.

PLease give a very good summary on the Cilia And Flagella.
Must be 1 paragraph atleast
(Please everything about must as much as you know please)
Answer:
Cilia and flagella are slender, hair-like structures that protrude from many types of cells. In many cells, cilia act as a fundamental unit of motion, serving as key organelles that convert chemical energy into mechanical work in the form of an oscillatory beating motion.Flagella acts primarily as an organelle of locomotion in the cells of many living organisms.In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them.Cilia are present on the surface of the cell in much greater numbers. Ciliated cells often have hundreds of cilia but flagellated cells usually have a single flagellum. The function of cilia is to move water relative to the cell in a regular movement of the cilia.
