Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. ... When a dominant allele is completely dominant over another allele, the other allele is known as recessive.
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. ... A heterozygous individual will appear the same as a homozygous dominant individual. This means that an organisms with two dominant alleles appear the same as an organism with only one functioning allele.
Answer:
c
Explanation:
active transport does move nutrients to areas with concentraition they do this and its called active transport because the body is activly moving it to a different part
Farmers should discontinue the use of Bt corn (genetically modified maize)as their negative affects on the health of the consumers have not been fully over ruled by the recent research. In my opinion, genetically modified crops, although, are resistant to various pests, should not be encouraged because of the toxic chemical contents used during their production. There's a strong likelihood of these toxic chemicals entering our food chain and also being harmful to other naturally growing plants, hence there's a need for more research before this idea is pursued.
Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.
Answer:
phylum Cnidaria
Explanation:
Cnidocytes represent a group of living organisms, whose members are Jellyfish, Sea Anemone, Hydra, Portuguese Caravel. Cnidocytes are found in the Cnidaria phylum.
Cnidaria, known in the past as coelenterates, are relatively simple animals with no circulatory and respiratory system, all of which are done through the diffusion process. They have diffuse nervous system and metabolism products are eliminated by mouth. The locomotion occurs through jets of water in the jellyfish and some polyps move slowly dragging or somersaulting.
