Students are each given a 20-gram sample of an unknown solid compound in a clear plastic bag. They are instructed to break the m

aterial into smaller parts by gently hitting it with a hammer. Some of the parts break into large chunks and some look like a fine powder.
Which statement correctly describes these broken pieces of the sample?
The fine powder pieces are individual atoms broken from the solid.
The larger pieces are still compounds and the smaller pieces are elements.
Each piece contains the same number of atoms.
Each piece contains the same proportion of different elements.

Answer:

The larger pieces are still compounds and the smaller pieces are elements.

Explanation:

Compounds are a mixture of different elements. So, when we break in into smaller(fine powder) pieces we get the individual elements. While, the larger pieces are still compound (mixture of two or more elements).

Help please !! I really don’t understand this much☹️

Ok, so I wrote these out just to make it a little bit easier for you to understand what I am about to explain.

So for the first one you have two different traits that can be inherited- having freckles or having no freckles, F and f respectively. The dominant trait (or having freckles) is shown by the capital F, and is almost always expressed over the recessive trait, or the lowercase f. So, for example, if you have a genotype of Ff, the trait having freckles will show up instead of not having freckles. The only way that you could have the trait of no freckles show up is if there are two recessive alleles for having no freckles, or ff. In this case, you have two parents who are both heterozygous for the trait of having freckles, so in other words the mother has Ff and the father has Ff. Each parent passes down one allele to the offspring, so since you are breeding Ff and Ff, you should result in having the possible genotypes of FF, Ff, Ff, and ff. This means that there is a 25% chance that the offspring will be homozygous for having freckles, a 50% chance that the offspring will be heterozygous for having freckles and a 25% chance that they would be homozygous for having no freckles, or a 1:2:1 ratio.

Incomplete dominance is a little bit different that just a normal monohybrid cross. Instead of just the dominant gene showing up in a heterozygous genotype, both traits show up. So like the question says, if a homozygous red flower plant was crossed with a homozygous white flower plant, their offspring would not just be white or red, they would be pink because it is a mixture of white and red. So then if you crossed the heterozygous, or Rr plants, the result would be a 25% chance of getting a homozygous RR red plant, a 50% chance of getting a pink Rr plant, and a 25% chance of getting a white rr plant, or another 1:2:1 ratio.

Sorry for the wordy answer, but hopefully this helps you understand this a little better :)

_____ fat is located deep within the abdominal region and protects digestive organs.
Ugo [173]

Answer:

Visceral fat

Explanation:

Just like all other fats, visceral fat is also body fat however it is specifically located in the abdominal cavity where it surrounds many critical body organs like kidneys, intestines, pancreas and liver.

it is important to understand the difference between other body fat and visceral fat. All other body fat is that which we store in thighs, arms and other skin organs, it is called subcutaneous fat and we can feel its presence. However, visceral fat is located deep inside or belly and we are not able to feel its presence but it do plays critical role in the protection of our organs and functioning of our body hormones.

Despite of its positive roles, an excessive amount of visceral fat in the body can be call for potentially threatening diseases like type 2 diabetes.

Hope it help!
