The genetic characteristic of two different organisms are induced into a new host organism for the purpose of producing new genes.
<u>Explanation:</u>
In the field of bio technology, Recombinant DNA technology plays a very important role. This helps in the production of genes. The first thing insulin of human was produced with this technology. In this technology, the gene that is to be produced is cut and it is placed inside a host organism where it gets multiplied.
This technology uses five steps in gene production. Firstly, the DNA that is essential will be cut. this is done by restriction site. PCR is used secondly in order to amplify the copies of the genes. Then these are induced into Vectors after which they will again be introduced into a host organism. Then finally the results will be the genes of the desired characteristics.
Bones: they lose calcium, becoming crispy
Muscle: they lose mass
Cartilage: becomes stiffer, but it does not make airway more rigid
D) connective tissue: It includes bone, blood, and lymph tissue, giving support to the skin and internal organs, becoming increasingly stiff when aging.
It should be connective tissue.
Answer:
The correct answer is option C. "Longer beaks allow the birds to better access seeds in bird feeders".
Explanation:
Since climate change makes more difficult for "<em>Parus major</em>" birds to feed from its primary source of food in gardens, the birds are adapting to access their second source of food, which is the bird feeder. Longer beaks allow the birds to better access seeds in bird feeders, therefore, the birds are developing longer beaks in order to adapt to their new conditions.
Answer: The correct answer is D
Explanation:
As long the progression of the cell to the M phase of the cell cycle is controlled by the chemical signals in the cytoplasm, then a cell in early M phase fused with a cell in G1 would result in the chromatin in prep of nuclear division in both cells to be condensed.
Answer:
The three sections of the small intestine are the duodenum,
Explanation:
The duodenum
It receives chyme from the stomachs
Its intestinal cells enzymes such as secrete amylase, sucrase, and lipase enzymes that break down fats and sugars.
The jejunum
It is covered in villi and microvilli giving the name THE PRINCIPAL SITE of digestion.
the ileum.
Aid absorption e.g. amino acids, lipids, fat-soluble vitamins, and vitamin B12.
