Hello there,

1.) According to the biomolecular data, we COULD infer that <span>humans are more closely related to chimps than any other apes. 

2.) </span>Based on the cladogram, if moths undergo complete metamorphosis, we would MOST LIKELY infer that <span>butterflies and flies do as well. 

3.) </span>According to the cladogram, which of these were the direct ancestors of the Kingdom Fungi? <span>Protista 

4.) </span>Trey is looking at a cell under the microscope. It is attached to many other cells, and it has a nucleus and membrane bound organelles. It has no cell wall. In which kingdom should this organism be classified? <span>Fungi 

5.) </span>A review of the cladogram shows a common ancestor for these four types of vertebrates. Which statement BEST explains the genetics represented by the cladogram? <span>Lizards and snakes are more genetically alike than lizards and birds. 

Hope this helps

Setler79 [48]

Answer:

Lobsters are adapting to cooler temperatures.

Explanation:

Adaptation may be defined as the phenomena that involves the physical, physiological and chemical changes in the organisms that helps to adapt themselves in their environmental condition.

The adaptation may bring genetic changes in the next generation as well. The lobsters movement per year demonstrates that they are trying to adapt in their environment. The cooler temperatures is favorable for the growth and adaptation of Lobsters.

A medical test indicates that a patient has a defective protein. This
OleMash [197]

Answer:

number of nitrogen bases

Explanation:

<em>The correct answer would be the number of nitrogen bases.</em>

<u>A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.</u>

Mutation can occur in a variety of ways including:

<em>1. Deletion of nucleotide base sequence in the DNA</em>

<em>2. Addition (insertion) of nucleotide base sequence in the DNA</em>

<em>3. Duplication of nucleotide sequence in the DNA</em>

<u>A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.</u>

Hence, the correct option is number of nitrogen bases.
