Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.
<h2>d) option is correct </h2>
Explanation:
The unfertilized egg contains various organelles and a liquid solution that fills the cell which is called the cytoplasm
Within that cytoplasm are various molecules containing genetic information or chemicals to spark various reactions, called cytoplasmic determinants
Some are different kinds of proteins, most are molecules of RNA and these determinants are unevenly distributed across the egg and then, once it's fertilized, the zygote
Once this zygote undergoes cleavage division, all of these random determinants that were in the same cell are suddenly in different blastomere cells, which means that these blastomeres each contain a different assortment of molecules
Answer:
Plasma plays an essential role of transporting nutrients and waste.
Explanation:
The largest constituent of the blood that comprises 55 percent of its entire constituents is the plasma. It is a light yellow liquid, which along with water transports enzymes and salts to different parts of the body. Plasma primarily plays an essential role in transporting hormones, nutrients, and proteins to different body parts.
Apart from this, plasma also carries waste materials withdrawn from the cells and discharges it out of the body.
The beak of a bird is important because it helps the bird eat certain foods that allow it to live. If a hummingbird did not have a long , thin beak, it would not get the flower nectar it needs. Or if a parrot did not have a large, blunt beak, it would not be able to eat hard seeds.
