Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).
<h3>
What are homologous structures?</h3>
A physical trait that distinguishes two or more species, such as a complicated bone structure or a body plan, may have been passed down from a common ancestor.
A common ancestor's evolutionary history causes physical characteristics to be homologous.
Sometimes, structures in an organism are similar to crucial structures in other animals, but they no longer serve the primary ancestral role. Vestigial structures are these structures, which are frequently scaled down.
Therefore, Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).

Answer:
d) "Tell me more about your fears and concerns."
Explanation:
Statement a) implies the nurse would be imposing her choice on the patient, instead of considering the patient’s concerns and assisting her in deciding a better treatment procedure to undertake.
Statement b) cannot be the best response from the nurse because, the suggested less invasive surgical operation procedure is limited in scope and may not adequately get all the affected tissues removed. The stage of the cancer and how severe it is should inform the type of treatment the patient can be advised to undergo. A combination of treatments might also be needed depending on the stage and nature of the cancer to be treated.
Statement d) is a better response compared to c) and b) and a). Getting to know the fears and concerns of the patient would help enable the nurse to ascertain if the patient has full knowledge about the scheduled procedure as well as address, adequately, the areas that needs further clarification and remove all fears and doubts the patient is having towards the procedure she has decided to undergo.
Answer – B (Electrons)
When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.
The correct answer is: C) the random and independent way in which each pair of homologous chromosomes lines upat the metaphase plate during meiosis I
Independent assortment is the second Mendel’s law which states that the alleles of two/more different genes are sorted into gametes independently.
When homologous pairs line up during the metaphase at meiosis I they do that random. This means that formed gametes will get different combinations of "mom" and "dad" homologues and consequently, different alleles on those homologues.
