Skates have whip-like and flat pectoral fins.
Explanation:
The tails of Ray and Skates are different from other fishes because Ray and Skates have whip-like tails that helps their kite shaped body in movement from one place to another. Both Skates and rays have pectoral fins that are flat and expanded, as well as fused to the head of both organism while on the other hand, fishes have different shape of pectoral fins that are not flat which helps to change the direction of the fish during its movement..

In his journey to the Galapagos Islands, Charles Darwin was amazed by the variation in the characteristics of plants and animals he encountered. In any habitat, food can be limited and the types of foods available may vary. One year, there was no rain on these islands. Many plants failed to bloom and produced no new seeds. This left mostly large, tough seeds for the finches to eat. Describe one change in beak characteristics that would most likely occur in the finch population after many generations if this change in seed size became permanent.

Answer:
Structure and is found in tendons, bones, and ligaments.
Communication and works as chemical messengers such as hormones.
Defense as in antibodies.
Transportation and are embedded in the cell membrane to allow substances to move across the cell membrane.
Enzymes that lower the activation energy of a reaction.
Contraction to allow muscle and cell contraction/movement.
Explanation:
Proteins serve many functions in living organisms.
Structure: The most abundant protein in mammals is collagen and is found throughout the body. In a major component of connective tissue such as skin, ligaments, and tendons providing strength and elasticity to these tissues. It is found also mineralized in bones and teeth.
Proteins function as hormones which are chemical messengers that mediate many cellular responses in the body. For example, the hormone insulin is a protein.
Proteins functions in the body's immune system as antibodies which recognize and initiate immune responses against diseases. The immunoglobulin such as immunoglobulin A and G are proteins.
Proteins serves as transporters to move substances across the cell memebrane. Some are found as peripheral or integral membrane proteins. Examples of transport proteins are the glucose transporters, Glut-1, Glut-2 and Glut-4 transporters.
Enzymes are proteins which catalyse the chemical reactions tanking place in an organisms. Various enzymes in the body include the hydrolases, the ligands, the leases, etc.
Contraction of the actin filaments of the muscle which are proteins, allow muscle and cell contraction bringing about movement.
A Note on the other options.
Eicosanoids are lipid molecules which serve various functions such as in regulation of blood pressure or inflammation.
Steroids such as cholesterol are lipid-derived molecules.
Glycogen for energy storage in muscles is a storage form of glucose, a carbohydrate.

A seed, known as "pinhão", is the great evolutionary novelty that is present in Gymnosperms plants. Choose the correct affirmative sentence related to seeds.
Answers
Hi. Unfortunately, you didn't show the answer options, which makes it impossible for me to answer your question. However, I'm going to give you some general information about seeds that can help you find the right answer. Hope this helps you.
Seeds are structures responsible for plant proliferation. They exist only in gymnosperms and angiosperms and are absent in bryophytes and pteridophytes. All seeds are formed in the ovary of flowers as a result of the plant fertilization process.
All seeds are formed by three structures known as integument, nutrient and embryo. The embryo is what gives rise to another plant, which will grow after the seed is planted and germinates. Nutrients will be responsible for meeting the needs of the new plant during the beginning of its development. The integument, in turn, has the function of protecting the embryo.

ow do cells use food to make energy and maintain homeostasis
Answers
Answer:
Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
Explanation:
There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.
