They need to break down the food and organisms inside of it before being able to use the nutrients in food.
Answer:
Explanation:
When cell divides, the DNA will replicate in the parent cell or make copies of itself and this will make the chromatics to split or divide in order to create a new cell or daughter cell which contain the exact same DNA. The daughter cell then pass these DNA to subsequent generations, when it also undergo cell division and the dna is been replicated
Answer: Germline mutation
A germline mutation is a mutation in the fully developed germ cells (sperm and ovum). These defective mutated cells fuse to form zygote. The zygote rapidly produces all somatic and germline cells in the offsprings which are also mutated. Therefore, mutation is transmitted from parents to offsprings. Cystic fibrosis is a result of germline mutation. This disease is hereditary in nature passes from parents to the offsprings. If a child receives CFTR (cystic fibrosis transmembrane conductance regulator) mutated gene from both the parents than the child will be affected by the symptoms of this disease. If the child receives a single copy of CFTR gene from either of the parent than the child will be the carrier of disease.The mutated gene may be present in the germline cells of the parent or on all the body cells.
Hi,
Electric charge drives this series of pumps and triggers known as ETS reactions.
The net effect of these reactions is the production of water and ATP on the usage of Oxygen (O2).
ETS reaction or Electron transport system comprise of sequential set of reactions that take place in a living cell and lead to the production of ATP so that organism can perform the day to day energy needing activities. The process of electron transport chain specifically takes place in the mitochondria of animals where different proteins and electron carriers are found. This system accepts the electrons from carrier molecules and then stores it in such a way that it can phophorylate Adenosine di phosphate (ADP) to energy rich molecule Adenosine tri-phosphate (ATP).
A total of 34 ATP molecules are produced in the reaction which then help the organisms to meet energy demands. This marks the last step of Aerobic respiration in animals. Please see the figure for better understanding.
Answer:
Since the sperm and egg each contribute 50% of the nuclear genetic material to the zygote that becomes the embryo, mitochondria and plastids that become chloroplasts are passed primarily from the female parent, due to a characteristic of the female gametophyte is be larger and formed from one surviving megaspore (option c).
Explanation:
The megaspore is the product of the meiosis of a megasporangio, the cula produces four structures of which only one is transformed into a megaspore.
The female gametophyte is formed from the megaspore which, being large and having a greater quantity of cytoplasm, contains the mitochondria and plastids that will originate the chloroplasts in the embryo.
