A light year is the distance traveled by light in a year.
Answer:
B. cv+cv w+w
Explanation:
Fruit flies have a special nomenclature to write the genotype of individuals.
- If the mutation is recessive, you have to write it with lowercase letter(s).
- If the mutation is dominant, you have to write it with capital letter(s).
- Wild-type alleles are indicated with a superscript plus (+).
In this problem, both crossveinless (cv) and white (w) mutations are recessive.
<u>For that reason, a heterozygous individual's genotype for both genes will be written as:</u>
<h2>
cv⁺ cv w⁺ w</h2>
Answer:
Explanation:
The molecule that results from translation is protein -- or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences.
<span>Erythrocytes, neurons, skeletal cells, and columnar cells are examples of: specialized cells.
cell, in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g., bacteria
and protozoans
, in which the single cell performs all life functions. In higher organisms, a division of labor has evolved in which groups of cells have differentiated into specialized tissues
, which in turn are grouped into organs and organ systems.
Cells can be separated into two major groups—prokaryotes, cells whose DNA is not segregated within a well-defined nucleus surrounded by a membranous nuclear envelope, and eukaryotes
, those with a membrane-enveloped nucleus. The cyanobacteria and bacteria (kingdom Monera
) are prokaryotes. They are smaller in size and simpler in internal structure than eukaryotes and are believed to have evolved much earlier (see evolution
). All organisms other than cyanobacteria and bacteria consist of one or more eukaryotic cells.
All cells share a number of common properties; they store information in genes
made of DNA (see nucleic acid
); they use proteins
as their main structural material; they synthesize proteins in the cell's ribosomes using the information encoded in the DNA and mobilized by means of RNA; they use adenosine triphosphate.
as the means of transferring energy for the cell's internal processes; and they are enclosed by a cell membrane, composed of proteins and a double layer of lipid
molecules, that controls the flow of materials into and out of the cell.</span>
