In one paragraph explain how plants get their food and what plants use food for.

Answers

Answer:

Photosynthesis is defined as the process in which the chlorophyll-containing plant

cells synthesise food in the form of carbohydrates, using carbon dioxide and water

in the presence of solar energy.

Sources of raw materials required for photosynthesis:

(a) Water is taken in from the roots of the plant and is transported to the leaves.

(b) Carbon dioxide from the air enters the leaves through the tiny pores called

stomata .

(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is

used to synthesise (prepare) food from carbon dioxide and water.

Thus, photosynthesis can be represented by the following equation.

Base your answers the questions below on the information provided and your knowledge of biology. Ocean-dwelling (marine) iguanas and land iguanas inhabit the Galapagos Islands. Some scientists believe that both types of iguanas diverged from a common ancestor. Marine iguanas eat algae. Land iguanas feed on cacti. Algae are more abundant in the ocean than cacti are on the islands. Both species lay their eggs in the sand. Rats, cats, and goats have been introduced to the islands by humans. Rats feed on iguana eggs, cats eat baby iguanas, and goats eat cacti. • Which population of iguanas, marine or land, would you expect to be larger? Support your answer. • Identify one technique that can be used to support the conclusion that these two species of iguana developed from a common ancestor.

Answers

Answer:

- The marine population is likely larger because the food supply is greater for the marine population than that of the land iguanas

- Evolution (natural selection), adaptive radiation

Explanation:

Evolutionary adaptation can be defined as the process of adjustment of organisms to particular environmental conditions in order to increase their chances of survival. Moreover, natural selection is the main mechanism by which organisms adapt to their environments. Adaptive radiation can be defined as the evolution of a specific taxonomic group (for example, a species o genus) into specialized organisms which are adapted to survive under particular environmental conditions. Adaptive radiation can lead to speciation by which populations evolve (change) to become distinct species.

1. Do plants, like animals, have traits that increase their reproductive success? What are some of these
traits?

Answers

Yes, they do. Many plants will have seed pods (like dandelions) that fly away or drop off. This helps distribute the seeds and promotes more plants being grown elsewhere. Another adaptation would be having their seeds inside fruits. This causes other animals to eat it and distribute the seeds that way in their waste.

Answers

Answer:

The correct answer is -  the more specialized pharyngeal jaws are for one diet, the less adapted they are for the ingestion of other foods

Explanation:

Pharyngeal jaws are also called throat jaws and are specific for the prey. These jaws have strong muscles and plastic or easy-to-modify teeth. If an organism has pharyngeal jaws specialized for a specific diet or prey it will have lesser chances to adapted well according to the new diet. For instance, pharyngeal jaws highly specialized for scale eating will not be able to adapt well if the fish ingests algae.

When a man has an allele combination Ww for a trait, what percentage of his gametes (sperm cells) will have a dominant allele for that trait? Answer format: XX%

Answer:

Explanation:

Gametes are haploid cells, and in humans, gametes each has only one allele.

The distribution of alleles is random, so on the average, 50% will have W (dominant allele) and the other 50% will have the w (recessive allele).
