Bacteria has a hard time getting inside a dry egg. Washing eggs removes the bloom and allows bacteria into the egg. Washing eggs in cool water pulls bacteria in even faster
More by hunger than by a wet diaper
50% are homozygous recessive. Homozygous simply means same letters, like rr or RR.
Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
Answer: True.
Explanation:
Glycolysis is a process that occurs in the cell cytoplasm, in which a 6-carbon glucose molecule is cleaved into two 3-carbon pyruvate molecules. Two molecules of ATP (Adenosine triphosphate, a molecule that acts as a source of energy to perform biological processes.) and two molecules of NADH are also obtained. It is a metabolic pathway responsible for oxidizing glucose in order to obtain energy for the cell. It consists of a series of consecutive enzymatic reactions, and when pyruvate is obtained, it continues to be used in other metabolic pathways in order to continue delivering energy to the organism. Glycolysis takes place both in the absence and presence of oxygen, so it is defined as an anaerobic process. Therefore, the final destination of the products obtained in glycolysis will depend on the conditions of the environment in which it is found, which will determine the metabolic pathway to be followed (i.e., whether oxygen is available or not). <u>In the absence of oxygen, glucose will not be completely oxidized to carbon dioxide and water, generating fermentative products</u> (lactic acid in animals and ethanol in yeast) producing only two net ATP molecules. <u>In the presence of oxygen, the pyruvate obtained during glycolysis enters the Krebs cycle</u> (to produce energy in usable form as ATP or GTP) <u>and then undergoes oxidative phosphorylation</u> (the process by which ATP is formed as a result of electron transfer from NADH or FADH2 to oxygen via a series of electron transporters) producing a net gain of between 36-38 ATP.
