What are the uses of plantae?
Virtually all the animals in the world depend on plants. They either eat plants or eat animals that eat plants.
Do the autotrophic cells in either plants or animals?
Only plants can be autotrophic (using light or chemical energy as their energy source). Animals are all heterotrophic.
Where are most zoologists found?
Where a zoologist lives will depend on how they are studying animals. Those who are studying animals in a laboratory can live almost anywhere. Those who are studying animals in their natural habitat would have to likely live in the wild for a period of time.
What is a glucomer?
If anything, it would be a polymer of monomers of glucose: either cellulose in plants or glycogen in animals.
Why doesn't a plant need a pump to transport materials unlike animals who have a heart to do the the job?
Not sure either
What do Radial and Bilateral have in common?
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral symmetry or "spherical symmetry". A small minority exhibit no symmetry (are asymmetric).
Are monotremes either asymmetrical or symmetrical?
Symmetrical. All mammals and, indeed, all vertebrates, have bilateral symmetry.
What is reflectional symmetry?
Um, it's the exact matching of parts on either side of a straight line, so it's exactly the same either side. I think It's sometimes called line symmetry, mirror symmetry or bilateral symmetry!
What shape has 2 equal sides 2 equal angles and no right angles?
An iscoceles triangle that is either obtuse or acute
What are the three types of body symmetry in animals?
Radial SymmetryRadial symmetry is rotational symmetry around a fixed point known as the center. Radial symmetry can be classified as either cyclic or dihedral.Cyclic symmetries are represented with the notation Cn, where n is the number of rotations. Each rotation will have an angle of 360/n. For example, an object having C3 symmetry would have three rotations of 120 degrees.Dihedral symmetries differ from cyclic ones in that they have reflection symmetries in addition to rotational symmetry. Dihedral symmetries are represented with the notation Dn where n represents the number of rotations, as well as the number of reflection mirrors present. Each rotation angle will be equal to 360/n degrees and the angle between each mirror will be 180/n degrees. An object with D4 symmetry would have four rotations, each of 90 degrees, and four reflection mirrors, with each angle between them being 45 degrees.Bilateral SymmetryBilateral symmetry is symmetry across a line of reflection. Are people symmetric? We think we are, but upon closer analysis, we are less symmetric than we think. The more simple the creature (ants --> elephants), the more likeley it is that it will be perfectly symmetric.We took two professors, cut and pasted half of their head in Photoshop, and flipped that half horizontally. We then aligned the two halves so that it came closest ro resembling a human head. You be the judge on how good of a job we did and how symmetric people around us are in general ...Asymmetrical SymmetryAsymmetry is the absence of, or a violation of, symmetry.
What kind of symmentary does a crab have?
Crabs have bilateral symmetry, which means you could place an imaginary mirror down the midline and observe a structural parity on either side. This characteristic is present in all arthropods.
How are advanced and primitive evolutinary forms for the traits of symmetry digestive system and segmentation different?
Primitive life forms tend to be asymmetrical with no body plan, while advanced forms have either radial or bilateral symmetry, which are both detailed body plans. Primitive animals also have a sac-like body plan with no specialized organs for digestion, while advanced animals have a tube within a tube body plan that contains specialized digestive organs for more efficient digestion. Primitive animals have very basic, unsegmented bodies with no appendages, while advanced animals have segmented bodies that allow for specialized limbs and body parts.
Does a flower have a rotational symmetry?
Yes it does. As long as it has a symmetry without rotation. If you do the rotation either way it does have symmetry. :)
What is the line of symmetry of an angle?
the distance from a point on either ray of the angle that is equidistance from the axis of symmetry is the line of symmetry. the line of symmetry dives the angle in half.
What is BILATERal hemothorax?
Hemothorax refers to an accumulation of blood in the chest cavity. Bilateral hemothorax would indicate that blood was found on either side of the sternum.
How many lines of symmetry does a paraelleogram have?
A parallelogram need have no lines of symmetry.
Does an equilateral and a octagon pattern have a line of symmetry?
Not necessarily. A rhombus is an equilateral quadrilateral but does not have a line of symmetry. An irregular octagon does not, either.
