Answer:
The foot
Explanation:
Mollusks have bilateral symmetry and are coelomed protostomes, but the coelom is only represented by small residual spaces around the pericardial cavity, the gonads, some parts of the nephridia, and in some cases part of the intestine. The foot is used primarily as a means of movement. The foot is also a very important structure, although it has adapted differently depending on the classes of mollusks. It is characterized by having a really powerful and complex musculature. The most widespread use of this organ is that of locomotion, as happens with gastropods. However, in bivalves it serves to burrow or in cephalopods it helps to provide propulsion.
Mitochondria if a plant and animal cell
Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Explanation:
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs. A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter.
