Answer:

Expected outcome: HH, Hh, Hh, and hh

The phenotypic ratio of the offsprings will be 3 hairy stems : 1 hairless stem

Explanation:

This question involves a single gene coding for possession of hair on stems or not in tomato plants. The allele for hairy stem (H) is dominant over the allele for a hairless stem (h).

According to this question, if two tomato plants that are heterozygous for hairy stems (Hh) are crossed, the following gametes will be produced by each parent: H and h. Using these gametes in a punnet square, the following proportion of offsprings will be produced:

HH, Hh, Hh, and hh

3 hairy stems (HH, Hh, Hh) : 1 hairless stem (hh).

<span>1. List five observations Darwin made about the Amblyrhynchus lizards.

a. They measure about 2-3 feet long.
b. They are cold-blooded.
c. They feed on crab and sea lion feces.
d. They are the only marine iguanas in the world.
e. Their nostrils are connected to salt glands that allow them to expel excess sea salt. 

</span><span>2. Describe two examples of structural adaptations that Darwin observed.

a. </span><span>Darwin discovered that finches in the Galapagos have thirteen different kinds of beaks. 
b. </span>Darwin observed two kinds of giant tortoises that are distinguished by the shapes of their carapaces (dome-shaped and saddle-shaped). 

3. <span>Describe two behavioral adaptations that Darwin observed.
</span>
a. <span>The marine iguanas have developed several ways of coping with the cold. At night, they huddle together for warmth. 
b. </span>In the face of famine, the marine iguanas have adapted by having the ability to shrink their body size. They are able to grow back to their original size once the food is supply increases.

4. <span>Explain how these observations influenced his theory of evolution?
</span>

These observations led Darwin to believe that if a certain trait is more advantageous in a specific environment, then the carriers of that trait are more likely to survive into adulthood and to generate offspring than those who do not have that trait. Eventually, the advantageous traits for a species will proliferate. Darwin later called this as "survival of the fittest".

Which of the following could be considered the most recent common ancestor of living tetrapods? a) a sturdy-finned, shallow-wate
tensa zangetsu [6.8K]

Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.

Explanation:

An ancestor - An earlier type of a species at any distant time — a progenitor.

A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.

The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.
