Among the ones listed above, the statement that best describes the way that the periodic table is arranged is "<span>The nonmetals are grouped together, which the exception of hydrogen.</span>" It can be seen that all of the nonmetals are placed on the far right of the periodic table except for hydrogen. They do not belong in a single column and are separated from the metals by the metalloids. Moreover, the elements are placed in the periodic table in increasing atomic number.
Answer:
Human diploid cells have 46 chromosomes
Explanation:
Plants are used for herbs, such as lavender, or other scented plants, like coconut and almond. Many plants are used for their medical properties, such a chamomile and jojoba. Plants can also be used to bathing or showering! Plants can be used in clothes, art, and symbolic uses!

Genetic engineering is the process of manipulating genes for practical purposes. today, scientists have genetically engineered many types of organisms including crop plants. which of the following is a current benefit gained from genetically engineered crops? a. some genes can be transferred to wild plants in the area. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients. d. some disease resistant fruits and vegetables are less flavorful.
Answer:
. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients
Explanation:
Rice is global staple food. It is mostly affordable by the poor and peasant farmer wordwilde.Vitamin A is an important vitamin for good eye sight and also for boosting the immunity.
This useful vitamin is present in eggs, cheese and liver. Which are expensive for poor families Some small quantity are produced as carotene found in carrot. However, a precursor of Vitamin A called Pro-vitamin A carotenoids is present in the part of rice called the Aleurone layer.
However this part of the rice is not in the endosperm thus the vitamin are washed way during processing of white rice .Although this is present in brown rice. Basically, the energy storage in most crop seeds is stored in the endosperm. Thus the vitamin in the rice are not stored are therefore not imbibe during consumption.
Therefore in order to incorporate carotenoid into the endosperm to avoid been wasted, Daffodil was used. The genes for the transcription of carotene in daffodils and from particular soil bacteria called Pantoea Anantis were extracted, to transfer carotenoid into the rice endosperm. This is called the Golden rice,, because the rice appear golden from the incorporation of the carotenoid into the endosperm though genetic engineering. This appear orange from the carotene pigment present in the endosperm.
Thus from the consumption of the rice ,poor family could imbibe vitamin A into their diet.
