By defects on the single germ lines in the reproductive cells.

Mutations can be caused by ultraviolet radiations from the sun or is the DNA copies itself during cell division. However, acquired mutations in somatic cells (cells other than sperm and eggs) cannot be passed to the offspring. When mutations occur in reproductive cells and are called germ line mutations. A single germ line can have a range of defects.

Answer:

a rat with rabbit hemoglobin genes

Explanation:

When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.

This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.

Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.

Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.

Genetically modified bananas as edible vaccines are another example

List two examples of how cells' shapes are suited to their functions?

sukhopar [10]

Answer:

Red blood cell in humans - it has no nucleus. Hence it offers the cell to carry more haemoglobin.

- they are disc shaped allowing them to pass through narrow capillaries.

Root hair cells in plants- they have a large cytoplasm which enables them to take water from the soil.

White Blood Cells in humans - they have lobed nucleus and so can change their shape to pass through narrow capillaries.

How long does it normally take to process one 12-ounce beer from your system?

Darina [25.2K]

Once the alcohol goes into our system, an ounce of it is process for a period of one hour.

The first stop happens in the stomach where absorption through the gastric lining and bloodstream occurs. Stronger drinks are absorbed more quickly. The second stop happens in the brain where its function decreases/ is increasingly impaired as the BAC or blood alcohol content grows. The third stop will be in the heart. However, it should be noted that it does not receive any physical alcohol, but its effects on the heart are strong. Alcohol is a vasodilator which means it causes blood vessels to dilate. This indicates more blood flow through the body-- but lowers the overall blood pressure. The fourth stop will be in the kidneys where blood is filtered. The fifth stop will be in the bladder where it will excreted from the body. Lastly, the liver is where the rest of alcohol left in your system is broken down. This process is known as metabolizing. The chemical that remains after metabolization is acetaldehyde and the body gets rid it by further metabolizing it into carbon dioxide and water.

Therefore, an ounce of alcohol is processed in our body for 60 minutes or one hour.
