The phylum Echinodermata , which contains about 6000 species, gets its name from the Greek, literally meaning "spiny skin." Many echinoderms actually do have "spiny" skin, but others do not. This phylum exists exclusively in the sea, and cannot be found on land or in fresh water. All echinoderms have one thing in common: radial symmetry. This means that the creatures have appendages (or body construction) which point outward from the center of the body like the spokes on a bicycle wheel. Furthermore, these appendages usually occur in multiples of five, although there are a few exceptions. There are several well known members of this group, like sea stars and sea urchins. The radial symmetry is obvious in these creatures.
Answer:
a. carry genetic information that influences the same traits.
Explanation:
Homologous chromosomes are the pairs of chromosomes. One chromosome of a pair is derived from the egg cell while the other comes from sperms. Two chromosomes of a pair carry the gene for the same traits. For example, two copies of chromosome 21 would carry the genes for the same traits in humans. However, these two chromosomes of a homologous pair may have the same or different alleles for a particular gene.
If chromosome 21 carries the gene for eye color in humans, the paternal chromosome may have the allele for blue eyes while the maternal chromosome may carry the allele for the black eyes. However, both of them have the "gene for the same traits (eye color)".
Answer:
Answer is hemoglobin S.
Explanation:
Hemoglobin S is considered as an abnormal type of hemoglobin which a child can be inherited from the parents. This cause the red blood cells to have distinct shapes from their normal shape. The red blood cells will have a sickle shape which is different from their normal round disk shape.
Answer:
1.fungi, 2.fungi 3.monera 4.fungi 5. protista 6. animalia
Explanation:
since, yeast is a fungus , penicilium and mushroom (agaricus) also fall under this catergory due to the <em>presence of mysceliom and hyphae.</em>
rizobium is a <em>bacteria</em> so falls under the kingdom monera
amoeba has <em>locamotory organs</em> hence is a part of the protista kingdom
while , fish is <em>an animal</em> and thus belong to animalia
