Answer: Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.

Connell's famous barnacle experiment was initiated to learn more about competitive exclusion and distribution of branacle species. Barnacle species are distributed in distinct zones on the rocky shores of the Atlantic coast. The Chthamalus in upper intertidal zone; is a smaller species and the semibalanus in low intertidal zone which is a larger species. Chthamalus found in the higher physical stress and higher temperatures because the low tide levels causes them to be exposed to the extreme outside environment for longer periods of time than the semibalanus. Additionally barnacles can only feed while submerged and the higher up shore a barnacle is, the less it can feed and grow. The experiment wanted to understand why they lived this way.
Answer:
Transferred to a different chromosome without a reciprocal exchange of genetic material
Explanation:
Translocation is one of the structural abnormalities of chromosomes. During translocation, a segment from the chromosome breaks off and attaches to the non-homologous chromosome. Translocation can be reciprocal or nonreciprocal.
In reciprocal translocation, the exchange of chromosomal segments occurs between two non-homologous chromosomes. On the other hand, the nonreciprocal translocation, one chromosome loses its segment to a non-homologous chromosome but does not get the same from the recipient chromosome.
Answer:
b. cis test
Explanation:
A test that is used to determine if the mutation associated with a given phenotype is due to mutations in two different genes or due to different alleles of the same gene is called a complementation test.
A complementation test is also called as a cis-trans test.
If the mutations in a complementation test are located on the same position then the genes are termed as being on the cis position otherwise on the trans-position.
A cis test, that is if the genes are located on the same position serves as a control for the complementation test.
The one that can be inherited is b-short temper but a-long toes can also be inherited.
