What else can I help you with?
What do the similarities between the skeletal structures of these four species most likely indicate about their evolutionary history?
These four species are distantly related and share a common ancestor.
What mineral is formed by an organism?
A pearl, primarily calcium carbonate, is formed by oysters and some other mollusks.
What do scientist infer from the similarities between these two structures?
What two structures
Why non silicate minerals have wider variety of crystalline structures than silicate minerasls do?
Non-silicate minerals contain oxygen and native elements. They have metallic and non-metallic lusters, and are very common.
How is deformation related to metamorphic rock structures?
deformation is related to metamorphic rock structures because deformation can create metamorphic rocks through the stress it creates, and also certain structures in the foliations of metamorphic rocks can indicate stress and stress direction from deformation. Some structures caused by stress are folds and faults, and the resulting indicators in metamorphic rocks include things such as sigma structures, Z structures, mica fish, boudinage structures and many others.
Nitrogen wastes are filtered from the coelomic fluid of mollusks by structures called?
nephridia
What physical structure is found in all mollusks?
It is actually only three common structures since not all mollusks have shells. Here it is: Head- structure that contains the mouth, brain and sensory organs Foot- muscular structure that extends from the body and is used for movement Mantle- fleshy tissue that covers and protects the internal organs. It also secretes the shell for most mollusks :) B) =3 -_-
What common features do mollusks have?
they are slick slop and slimy
What muscular body feature that all mollusks have in common?
foot
What common feature do all mollusks have?
they are slick slop and slimy
Do mollusks and segmented worms share a common ancestor?
Yes these two share common ancestors.
Are mollusks segmented?
No ......mollusks are not segmented,like insects....just their body is partitioned into head, foot, and visceral hump..........but one can't take it as segmentation.........
What evidence indicates that annelids and mollusks are closely related?
Gene based phylogenetic studies indicate that annelids and mollusks share a recent common ancestor
What do mollusks and segmented worms have in common?
wat do all the worms have in common
What is the evidence which shows that mollusks and annelids share a common ancestor?
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
What products are made from mollusks?
There is a wide array of products that are made from mollusks. Some of the common products include pearls, wood adhesive and so much more.
Structures that share a common ancestory or a similar because they are modified versions of structures from a common ancestor are?
Homologous structures.
