Question 1
weqwewe [10]

The correct statement is D. The mental region is superior to the nasal region.

The different terms in the statements are anatomical terms. We use them to describe the regions and locations of organs.

<h3>Why are the other statements incorrect</h3>
  • The pubic region is inferior to the pelvic region: inferior means is lower. However, the pubic region is higher than the pelvic region.
  • The olecranon region is distal to the carpal region: we describe organs and bones in relation to the nearest parts to the axis of the body. In other words, we describe things from proximal (to the column and head) to distal. So, the carpal is distal to the olecranon.
  • The heart lies dorsal to the vertebral column: dorsal means behind. The heart lies ventral to the column. In other words, towards the front of it.
  • The sternal region is lateral to the axillary region: we describe locations from proximal to distal, so the axillary region is lateral to the sternal region.

In conclusion, the correct option is: The mental region is superior to the nasal region because the mental region is the one that is above the nasal one in the skull.

Answer and Explanation:

Greetings!

Let's~answer~your~question!

<em>Q1. Assume that an organism exists in which crossing over does not occur, but that all other processes associated with meiosis occur normally. Consider how the absence of crossing over would affect the outcome of meiosis.</em>

→ There~ would ~be~ less~ genetic ~variation~ among ~gametes.

Thus,~making~statement~``e"~correct!

Hope~this~helps!~Have~a~blessed~day~ahead!

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?
astra-53 [7]

Answer:


2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG

Explanation:

Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!

In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G

In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.


In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.


In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.


Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
