Answer:
Amoeba;
Explanation:
Amoeba:
Amoeba will contain nucleus (contain the genetic information). Nucleus normally appears as dense circular mass under microscope.
Organelles are present. Organelles appears like distinct masses that are rounded in shape and smaller than nucleus.
Plasma membrane is present.
Bacteria;
Nucleus will be absent in bacteria. The nucleoid normally appear lighter in color under microscope.
Ribosomes will be present. Ribosomes appears like black dots within the cytoplasm.
No plasma membrane will be present.
The zooplankton community is an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain, transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.
Zooplankton are good indicators of change in nutrient pollution over time because they respond quickly to changes in nutrient input to the waterbody.
Answer:
Explanation:
Transcription and translation The information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus during the transcription process. During protein synthesis, translation is the process of converting the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids. The genetic code describes the relationship between the base pair sequence in a gene and the amino acid sequence that it encodes.
Answer:
A) one human somatic cell
Explanation:
A human genome is a complete set of DNA in somatic cell and it contains 23 chromosome pairs (nuclear genome). Beside nuclear genome cell also have mitochondrial genome. Unlike somatic cells (diploid-two sets of chromosomes, one from mother and one from father), germ cells (egg cell and sperm cells) are haploid, have only one set of chromosomes.
Human genomes include genes that are protein-coding but also noncoding DNA.
Answer:
Explanation:
n other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele. ... The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.
