Answer:
A cell in an isotonic solution is in equilibrium with its surroundings, meaning the solute concentrations inside and outside are the same (iso means equal in Latin). In this state there is no concentration gradient and therefore, no large movement of water in or out. Explanation:
Answer:
Is the merging of DNA from unrelated organisms to create new genetic varieties
Explanation:
Recombinant DNA creates transgenic organisms. Foreign DNA from another species can be incorporated in the genome of another species through several ways such as electroporation and transduction. The transgenic organism will, therefore, exhibit traits coded for by the foreign genetic material. This form of biotechnology/genetic engineering is used to modify characteristics of an organism so it exhibits desired traits.
D I believe that’s the answer
Answer:
Either a vacuole or a chloroplast
Explanation:
Chloroplasts are the site of photosynthesis and animal cells do NOT photosynthesise
Vacuole stores the cell sap in the plant cell
cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.
Explanation:
The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.
The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
