Answer:
Natural and Basic resources.
they are needed by plants to grow
Answer:
It is a route in which N2 in the atmosphere is converted into ammonia by prokaryotes using an enzyme complex (Nitrogenase), and an N pool is maintained in the ecosystems, which replenishes N losses. BNF occurs naturally in the soil by N fixing bacteria (Rhizobium and legumes/Azotobacter)
<h2>Postulates of natural selection</h2>
Explanation:
- Early in development, all vertebrate embryos are remarkably similar. The similarities among the embryos imply that the development of all vertebrates (having a backbone) evolved as new genetic instructions were placed on Top of older ones.
- The chick embryo is on the right. It is easier to compare a newly hatched chick and a newborn baby. After birth, a backbone or vertebrae are clearly visible, as are legs, a mouth, a pair of eyes, etc. The chick’s Skeletal system, in general, has multiple similarities to ours, including having one bone in the upper leg and upper wing and two bones in the lower leg and lower wing. This mimics our arm and leg skeletal structures.
- Mammals, birds, reptiles, and fish, look very similar at the earliest stages of growth inside the womb of the mother animal.Vertebrate embryos begin developing similar features due to related ancestors. As the embryo grows, it may drop some of these ancestral traits as the genetic code becomes more specific for that species.
Answer:
I think the answer will be c..
Answer:
C
Explanation:
Green Plants are the main producers of starch as carbohydrate.In order to carry out this special organelle Chloroplast are specially adapted for this purpose,
Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.
Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water in the presence of sunlight and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.
This process occur in two pathways the light dependent pathways and the light independent pathways,
Green plant and some organisms phytoplankons,algea are capable of producing starch through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.
