Answer:
emigration
Explanation:
The emigration of an animal, in this case of the antelope, is the cause of the lack of food.
The animals are in constant search of food and better places to cohabitate. Antelope is leaving its herd to find a better place for food and even if it sounds strange, animals are also behaving as individuals in case there is threatening of hunger.
Answer:
Liver.
Explanation:
The liver is a dark reddish organ that is situated in the right hypochondriac or upper right hand region of the abdomen, just below the diaphragm and anterior to the stomach in the epigastric region, the right kidney and the small intestines.
It is the second largest organ of the body, second only to the skin. The liver is divided into four lobes which include;
1) The right lobe
2) The left lobe
3) The quadrate lobe and
4) The caudate lobe
The blood supply to the liver include;
1) The hepatic artery
2) The hepatic portal vein which supplies the liver with nutrients-filled blood from the small intestine. It is the main blood supply to the liver.
The venous drainage is through the hepatic veins.
The nerve supply is through the hepatic plexus made up of sympathetic and parasympathetic nerves.
The liver plays a major role in the processing and metabolism of food and ingested substances and also detoxification.
Answer:
An Oc mutation on the bacterial chromosome can affect the expression of structural genes on a F plasmid.
Explanation:
An Oc mutation is a mutation in which operator of an operon is constitutively active i.e. repressor fails to bind the operator which leads to unregulated gene expression.
An Oc mutation do not affect the expression of structural genes on F plasmid because <u>an operator is a cis regulatory element and therefore it can only affect the genes which are located on the same DNA</u>. F plasmid genes are located on the plasmid not on the main chromosome of the prokaryotes while tryptophan or lac operon system is in the main chromosome that is why an Oc mutation will not impact genes on plasmid.
Because your body maintains your own thermistat and so your body recycles the heat being produced
