¿Por qué consideras importante la medición de propiedades y/o fenómenos en las ciencias experimentales?

Answers

Answer:

una medición debe ser precisa y objetiva ya que sólo de este modo es posible reproducir el diseño experimental en condiciones controladas

Explanation:

Las ciencias experimentales son aquellas que realizan estudios en condiciones controladas (experimentos) con el objetivo de comprender el mundo natural que nos rodea. La medición juega un papel crucial en las ciencias experimentales ya que sólo una medición precisa y objetiva permite reproducir los resultados obtenidos en diferentes experimentos. De este modo, el proceso de cuantificar magnitudes está directamente asociado a la confiabilidad de los datos obtenidos en un experimento y consecuentemente también a la confiabilidad de las conclusiones derivadas de la aplicación del método científico experimental.

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.

Answers

Hardness, hope this helps

The mineral property which cannot be used to identify a mineral is: 1. mass

A mineral refers to any form of naturally occurring, inorganic solid substance that is typically characterized by a crystal structure.

This ultimately implies that, minerals are homogeneous in nature with a well-defined chemical composition and they are characterized by a crystal structure comprising ions, atoms, or molecules arranged in an orderly manner.

Generally, the mineral property which can be used to identify a mineral include the following:

Luster.Hardness.Streak.

For example, hardness of a mineral can be tested by scratching its surface with a knife or your nails.

However, mass isn't a mineral property that can be used to identify a mineral.

Which of these statements correctly describes one way that asexual and sexual reproduction are alike?
A. Both types of reproduction require two parents to produce offspring.
B. Both types of reproductions result in offspring that are identical to one parent.
C. Both types of reproduction enable genetic information to be passed from parent to offspring.
D. Both types of reproduction can occur in all organisms, depending on environmental conditions.

Answers

C. Both types of reproduction enable genetic information to be passed from parent to offspring.

It doesn't matter if the reproduction is sexual or asexual, because the offspring has the parent(s) dna and genetics either way.

The primary similarity between sexual and asexual reproduction is that they both have as their primary goal the generation of progeny into which genetic information is passed on, hence option c is correct.

What is the difference between asexual and sexual reproduction?

Asexual reproduction only requires one organism to create more offspring that are identical to the parent and each other.

A male and female cell combine during sexual reproduction to create children that are genetically distinct from their parents.

Sexual reproduction needs both a male and a female organism, as opposed to asexual reproduction, which only includes one organism.

Therefore, the benefits of sexual reproduction include the offspring's genetic diversity, hence option c is correct.

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
