Answer:
The process by which plants make food through sunlight is called photosynthesis...
Answer:
a. Excretion is accomplished by paired protonephridia with flame cells in every segment of the body. True
Most anelids have structures called metanephrids or protonephridia. Both structures are homologous to the kidneys and have the function of excresion, A pair are present in every segment of the body.
b. If the organs in one segment fail, the organs of another segment will still function. False
It is false because all segments are interrelated and have different functions depending on their location.For example, the first segment is where the sensory appendages are, such as the antennae and the eyes. The second segment is where the mouth is. There are a series of parapod segments to move, collectively called metameres and ends in a terminal portion called pigidium, where the anus is located.
c. Annelids possess both circular and longitudinal muscles that produce waves of contraction that are propagated down through the points eBookseries of segments.True
True because anelids have circular and longitudinal muscles that serve to function the hydrostatic skeleton.
d. Segmentation has allowed for specialization in the anterior of the annelid body, which has provided for a more sophisticated nervous system. True
True because the segmentation allows to have a nervous system formed by a ventral nerve cord provided with ganglia and lateral nerves in each segment.
False it is does not have plants it can be release oxygen gas to the atmosphere
In moving from the outside environment to the inside of a bacterium, the first layer encountered would be Glycocalyx.
The cell coat or outermost layer of bacterial cells is called the glycocalyx. Glycoproteins, glycolipids, and proteoglycans make up its composition.
It is a network of lipids and membrane proteins connected by polysaccharide chains. On the lumen side, it encircles the vascular endothelial cells.
Various bacteria have varied glycocalyx layers with different compositions and densities. It serves as a protective layer and participates in cell interaction, signalling, and identification.
