The correct answer is (C) biomass at each trophic level
Pyramid of energy is a graphic representation of amount of energy trapped per unit time and area in different trophic levels of a food chain with producers forming the base and top carnivores the tip. As the biomass of producers are always greater than the carnivores, the pyramid of energy can't be inverted.
Two reasons Eugleoids are considered to be animal-like is because they can move from one place to another, and are heterotrophic (consumes food made by other organisms) or >> reproduces by fission << could be another option.
Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
Answer:
Bb, Db
, Bd and Dd
Explanation:
When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A genetic cross can be represented by a punnet square (as given below)
The cross between two parents with genotype "BD" and "bd" will result into the following offspring -
B D
b Bb Db
d Bd Dd
Answer:
Explanation:
Energy in _SUNLIGHT__ is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC. The ETC creates _AN ENERGY GRADIENT__ which is used by the cell to power the formation of ATP. In _CYCLIC PHOSPHORYLATION__ (cyclic or noncylcic) the electron returns to the photocenter. In _NON-CYCLIC PHOSPHORYLATION__ (cyclic or non-cyclic), the electron reduces NADP+ to form _NADPH__.
Photophosporylation is the process of using light (photo) to produce ATP from ADP (phosphorylation i.e. addition of phosphorous). There are two types: cyclic and non-cyclic phosphorylation.
In non-cyclic phosphorylation, there are two photosystems (photocenter) involved, and electron is passed to NADP+.
In cyclic phosphorylation, one photosystem is involved and the electron is not transferred to NADP+, it is circled back to the photosytem.
The reduced form of NADP+ is NADPH. (Remember that: reduction is defined as the addition of hydrogen)
