Do porcupines have radial symmetry or bilateral symmetry?
Porcupines have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What is symmetry and plane symmetry?
There are three elements of symmetry: 1-axis of symmetry It's a line which cuts the molecule into two equal halves. 2-plane of symmetry It's a plane which cuts the molecule into two equal halves (such as 'axis of symmetry' but axis is a line and here it's a plane). 3-center of symmetry It's a point in space that, if you draw a line from any part to it, and then extend the line beyond it, another atom will be encountered.
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.
What balance features unlike objects on either side of an imaginary line?
The balance features that differentiate unlike objects on either side of an imaginary line are symmetry and asymmetry. Symmetry refers to a balanced arrangement where corresponding parts on either side of the line are identical or mirror images. In contrast, asymmetry involves an imbalance where the objects differ in shape, size, or other characteristics, yet can still create visual interest or equilibrium through their distribution. This concept is often utilized in art, design, and nature to convey harmony or tension.
How can magnetic symmetry can be used as evidence of seafloor spreading?
Magnetic symmetry refers to the pattern of magnetic anomalies found on either side of mid-ocean ridges, where the Earth's magnetic field has reversed over geological time. As magma rises and solidifies at these ridges, it records the Earth's magnetic orientation, creating symmetrical patterns of magnetic stripes on the seafloor. This symmetry indicates that new oceanic crust is continuously being created and pushed outward, supporting the theory of seafloor spreading. The parallel arrangement of these magnetic anomalies on either side of the ridge provides evidence of the age and movement of tectonic plates.
How are most animals classified based on their symmetry?
Animals are classified based on their symmetry as either radial or bilateral. Radial symmetry means the animal can be divided into equal halves in multiple ways around a central point, like a starfish. Bilateral symmetry means the animal can be divided into two equal halves along a single plane, like a human.
What is an advantage of bilateral symmetry?
Celiaphlatus and forward movement. There is a few advantages of the bilateral symmetry. Some of the advantages are food, movement and animals.
Is an alligator bilateral?
Yes, alligators are considered bilateral organisms because they exhibit bilateral symmetry, meaning their bodies can be divided into two equal halves along a single plane. This symmetry allows for balanced development of body parts on either side of the plane.
Are monotremes either asymmetrical or symmetrical?
Symmetrical. All mammals and, indeed, all vertebrates, have bilateral symmetry.
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).
Do porcupines have radial symmetry or bilateral symmetry?
Porcupines have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What is an antilopes symmetry?
Antelope symmetry refers to the bilateral symmetry observed in antelope species, where their body structure is symmetrical on either side of a central axis. This type of symmetry is common in many animals and allows for balanced movement and efficient navigation through their environments. Antelopes typically exhibit features such as symmetrical horns and limbs, contributing to their overall agility and gracefulness in the wild.
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 symmetry does a snake have?
Lizards, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
What type of symmetry do sponges exhibit How does this differ from organisms belonging to phylum Cnidaria Arthropoda?
Sponges exhibit asymmetry, meaning they lack any distinct symmetry. In contrast, organisms from phylum Cnidaria and Arthropoda typically exhibit radial symmetry (such as jellyfish) or bilateral symmetry (like butterflies), respectively, where body parts are arranged around a central axis or mirror images are present on either side of the body.
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.
