Which features of how seedless land plants get sperm to egg are the same as for some of their algal ancestors?
Ket [755]

Answer:

Flagellated sperm swims to egg in water drop.

Explanation:

The seedless land plants reproduce through the production of unicellular haploid cells which disperse easily because it is light weight. The male antheridium releases sperm. This sperm has flagella which is use for swimming in water or moist environment to the female archegonia to fertilize it and produce embryo. This embryo develop in the sporophyte.

The algae sperm also have flagella for swimming in water to meet and fertilized the egg to produce embryo.

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".

"what is the relationship between the motor neuron axons and muscle fibers"
fomenos
Motor neurons carry impulses to the effectors in the body, which are the muscles or glands that produce a change based on a stimulus sensed by the receptors. The motor neurons "innervate" muscle fibers, which essentially means that they cause them to move. The fewer the muscle fibers associated with a motor neuron, the more precise are the movements of those fibers. Having to control a small number of fibers, the neuron is able to coordinate more dexterous motions. An example of a region where there are not a lot of muscle fibers related to each neuron is in your fingers.
