What is the empirical formula of a compound that contains 4.03 g of hydrogen per mole, 64.14 g of sulfur per mole, and 128.00 g of oxygen per mole?

Answers

Answer:

Oct 27, 2015 · CH_4 For this kind of problem, you can assume that the weight of the unknown sample is 100g ( since 75% C + 25% H = 100%). Thus, weight of C = 75g weight of H = 25g Since chemical formulas deal with number of moles rather than weight in grams, you need to convert each element by multiplying it to their respective atomic masses.

Explanation:

The empirical formular i H₂SO₄

The first step is to calculate the compound by the molar mass

Hydrogen, Sulphur, Oxygen

4.03/1 , 64.14/32 , 128/16

4.03 , 2 , 8

Divide by the lowest value

4.03/2 , 2/2 , 8/2

2, 1 , 4

H₂SO₄

Hence the empirical formula is H₂SO₄

is broccoli a dicot or monocot?

Answers

Answer:

Broccoli is a dicot

Explanation:

I looked it up on the internet :)

Unlike monocots, the pollen grains of dicot plants have three pores and are called trisulcate. Dicot plants can also have bark and secondary growth increases the diameter (girth) of the plant. Examples of dicots include potatoes, tomatoes, apples, pears, peaches, cauliflower, peppers, broccoli, and cabbage.

Foods that are dicot: Dicots - Flowering plants with two seed leaves. Examples of these are: fruits, vegetables, mangoes, lentils, blackberries, potatoes, and avocados.

Foods that are monocot: Other economically important monocotyledon crops include various palms (Arecaceae), bananas and plantains (Musaceae), gingers and their relatives, turmeric and cardamom (Zingiberaceae), asparagus (Asparagaceae), pineapple (Bromeliaceae), sedges (Cyperaceae) and rushes (Juncaceae), and leeks, onion and garlic ( ...

what are some drawbacks to using mice in genetic studies?

Answers

Answer:

One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.

hope this helps

Explanation:

Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.

Why it's bad to use mice as an experiment:

The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

_________________________ happen when extra base pairs are included in an existing DNA sequence.

_________________________ happen when base pairs in an existing DNA molecule get removed from it.

Fill in the blanks correctly

Answers

Answer:

Explanation:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

What are Prokaryotic and Eukaryotic cells?

Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.

Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.

Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Gymnosperms. Angiosperms, additionally referred to as flowering flowers, have seeds which are enclosed inside an ovary (normally a fruit), even as gymnosperms don't have any plant life or end result, and feature unenclosed or “uncovered” seeds at the floor of scales or leaves. Gymnosperm seeds are regularly configured as cones.
