Answer:
In the animal cell the organelles that is labelled G is mitochondria.
Explanation:
Mitochondria are the membrane bound organelles with inner membranes folded inside which can form finger like structures called cristae. There numbers are more in the cell. They are basically responsible for the production of the energy, hence called as the power house of the cell. They also perform the cellular respiration, which means it takes the nutrients from the cell breaks it and makes energy from it. This energy is used by the cell to carry out various life processes.
Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%
A food web does not represent all the links in an actual ecosystem.
Explanation:
A food web is also called food cycle. It is understood by the natural interconnection of chain and their graphical representation. The concept is given by Charles Elton. He mentioned about the concept of food cycles in Animal Ecology but later this food cycle is replaced by food web.
Food web are limited representation of eco system. Ecologists can keep together all life forms broadly into one of the two categories which is called tropic levels. These two categories are autotrophs and heterotrophs
Correct answer: B). Cells spend the most time in interphase, where they grow and their DNA replicates.
The cell spends its most of the time in the interphase, during this phase of growth, cell continues to grow and carry out its metabolic activities which are necessary for regular growth and maintenance.
During this phase of the cell cycle, a lot of protein is synthesized in order to double its size. The important changes that occur in this phase include DNA duplication and division of chloroplast and mitochondria.
Hence, the correct answer would be option B.
