A whelk is a carnivore: <span>True whelks are carnivorous, feeding on worms, crustaceans, mussels and other molluscs, drilling holes through shells to gain access to the soft tissues</span>
Active muscles demand huge amounts of oxygen, and the circulatory system works hard to provide it. Blood carries oxygen to the muscles. When the body is at rest, blood carries nutrients to the muscles so that they can repair and rebuild themselves. Blood also carries away the waste products that hard-working muscles produce, back out through the lungs to be filtered.
so they Circulatory system xx muscular system :)
The environmental effects of harmful practices on private property are not essentially restricted to private property, it can also affect public property. Water polluted on private property might stream down into a local river or an aquifer used for public purposes like drinking water or for recreational parks (swimming pools). Landowners who slaughter travelling animals on their property are putting an end to creatures that are part of a bigger ecosystem; the loss of these animals will affect all the ecosystems along the migration route.
Answer:
The difference between Prokaryotic cell and Eukaryotic cell are;

Explanation:
Prokaryotic cells
The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells
Eukaryotic cells
Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
Answer:Bb
Explanation:
Homozygous gene pair are pair of allele that are identical e.g BB
Heterozygous gene pair are pair of allele that are not identical e.g Bb
Heterozygous gene pair could show complete dominance where the Allele for dominant will completely mask the effect of the reccessive allele and the individual will express the trait of the dominant allele.
