how might genetic variation arise?

Answers

Answer 1

Answer:

Genetic variations can arise from gene mutations or from genetic recombination (a normal process in which genetic material is rearranged as a cell is getting ready to divide). These variations often alter gene activity or protein function, which can introduce different traits in an organism.

Should girls cook during menstrual days or not? Why? plz tell me fast​

Answers

Answer:

IN OLDEN TIMES:

A girl, when she reaches puberty is barred from entering the prayer room or performing any religious prayers during her menstruation. The only reason mentioned in our scriptures is that she is (ashudha) unclean during that period.

During ancient days, women would take bath in the river, pond or near the well. During the time when the girl would be menstruating, it would be awkward to bathe outside in the river as it would probably ‘pollute’ the water.

So, the ladies did not take bath. Since the ladies did not take bath, they were naturally termed ‘unclean’ during that time. Hence, their being barred from the clean’ places in the house, namely the prayer room or the kitchen.

However, Science has a different meaning for the menstruation. As per science, a woman is more irritable during those days because of a hormonal imbalance. Psychics claim that there is a different aura around a menstruating woman, maybe again a chemical reaction.

Segregating to pray requires a positive attitude and people tend to respond to the negative virations of a person standing with you; maybe that was the reason why a woman was barred from public places and the kitchen.

TODAY:

Times have changed,

It is the old saying of old people. But of a girl cooks during periods then it is not to become bad in taste or it won't get spoiled. The taste of food is going to be same as she cooks on other days. So I think this saying is wrong and girls can cook during their mensuratl days. It is a natural cycle and they r not responsible for it

Answers

Answer:For more plants to have blue berries

Explanation:

If the birds only like to eat blue berries in an environment with blue and red berries, the birds are putting selection pressure for more plants to have red berries.

Selection pressures are factors that act to boost or limit the organism's capacity to thrive in an environment. It could be biotic or abiotic.

The availability of purple berries in the environment is dependent on the mixing of both blue and red berry alleles.If birds keep picking on the blue berries, it means fewer blue berries would be available to mix with red berries in order to produce purple berries.Hence, fewer blue and purple berries would be available in the environment with time leaving only red berries to thrive.

In other words, the continuous picking on blue berries by birds will only increase the availability of red berries with time.

Explain what genetic engineering is, and give real life examples (more than 1) of humans introducing a gene from one creature/plant into another creature/plant. Why did humans do this? Was it successful? Help me please this is due in around 3 hours

Answers

Answer:

Genetic Engineering also known as genetic modification are techniques used to transfer genes from the cells of a donor organism to those of a recipient.

One example is the formation of golden rice. 3 types of genes are added. Two come from daffodils and one from a bacterium, together forming beta-carotene, the chemical which give carrots their colour hence the name 'golden rice'. This is an advantage in LEDCs as beta-carotene is converted to vitamin A, which could save the eyesight of millions of children.

Another example are bananas. The genes that produce antigens to a certain disease are taken and transferred to bananas. The antigens contained in the banana will stimulate an immune response. This has successfully prevented diseases, and it will not be necessary to get needles stuck in you. This can be a very efficient method of preventing diseases in countries that has bananas as their main source of calories.
