Given the answers;
a) Reptiles
b) Cactus plants
c) Small birds
d) Crabs and crayfish
The answer is C. Small birds.
On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to Island, which helped him to develop his theory of natural selection.
Your answer would be B. The first one would be correct if the question was “how do we identify both bloodstains are from the victim”.
Because there is only a finite amount of energy. Energy is lost between each trophic stage. The top predator would gain the least amount of energy, shared between the least amount of organisms within the predator species. Typically there just aren't any other animals that can kill and eat the top predator, but there also wouldn't be enough of the top predator to eat so any species above them would quickly die out.
Answer:
It is important that cell growth in a multi-cellular organism be regulated carefully so as to maintain the integrity of the cell cycle
Explanation: Each cell in a multi-cellular organism has it cycle which consist of the inter-phase and the m-phase (active division). Cell growth takes place in the G1 phase of the inter-phase and this ensures that deoxy ribonucleic acid is synthesized in the S-phase in preparation for division.
Hence, adequate cell volume is a key event in order for division to take place. If cell growth is not regulated, it might result in a cell exiting the cell cycle into the resting phase in case of slow growth or result in over-division of a cell in case of over-stimulated growth. The latter is often the case in the development of cancerous cells.
Answer and Explanation:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs. The cells undergoing meiosis have only one interphase. After telophase I the cell enters into prophase II without having interphase II.
