Is extensive loss of hair observed in humans and whales an example of homoplasy or homology? see section 25.1 (page 497) ?

Biology

marin [14]3 years ago
3 0
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.

What is the difference between Genes and Alleles?
Vanyuwa [196]
Genes is found in the DNA. It decides a specific characteristic. Genes can transform and take two or more option structures and these structures are called Alleles. Presently allele happens in an altered spot in a chromosome and in people we have two arrangements of chromosomes.

There are 46 chromosomes in the human. 23 from the dad, 23 from the mother = 46 chromosomes.

Determine how to make positive and negative ions. Based on your exploration which subatomic particle is positive? Which subatomi
Katena32 [7]

Answer:

Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.

An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)

A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.

A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.

The subatomic particle that is negative is the 'electron'.
