Answer:
The homogeneous mixture is only in the one phase of matter, whereas heterogeneous mixture is always in two or more than two different phases of matter. Solutions are termed as the homogeneous mixtures, on the other hand, suspensions or colloids are termed as the heterogeneous mixtures.
Examples:
Homogeneous:
Bronze: this alloy is an example of homogeneous substances since it is composed of tin and copper.
Milk : this mixture that we see in a uniform way is composed of substances such as water and fats.
Heterogeneous:
Mixtures in two or more phases are heterogeneous mixtures. Examples include ice cubes in a drink, sand and water, and salt and oil. The liquid that is immiscible form heterogeneous mixtures. A good example is a mixture of oil and water.

Which of the following is true about the structure of water?
1. It is held together by an ionic bond
2. It is nonpolar
3. It is polar
4. It has one positive hydrogen attached to one negative oxygen
Answer:
3.) It is polar
Explanation:
Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. Other molecules, such as Ethane, are nonpolar, having neither a positive nor a negative side.
A landscaper is shopping for landscaping materials. She wants to use materials through which water flows easily. Which two materials should she choose? Clay and gravel gravel and loosely packed soil granite and rocks with cracks rocks with cracks and clay
Answer:
The correct answer is - Clay and gravel
Explanation:
Water can flow from the substance or material with greater porosity which is the number of pores resent in the particles of soil for easy exchange of water and gases.
Clay particles exhibit a higher amount of pores that permit the water to flow from it. Gravel allows water to pass from it as it is a loosely packed fragment of rocks
Answer:
gravel and looselypacked soil

How are photosynethis and cellular respiration similar? And how are they different ?
Answer:
Photosynthesis, carried out by sunlight-reliant producers, requires carbon dioxide and releases oxygen and glucose, while cellular respiration (carried out by animals) requires oxygen and releases carbon dioxide and ATP. However, they both are biological processes that supply the organism in question with energy.
Explanation:
Answer:
The answer will be listed below.
Explanation:
The two processes, photosythesis and cellular respiration, are similar in that they both produce energy. These are ways for organisms to produce their food. Although, these two processes are completely different from each other. Cellular respiation occurs in all living organisms while photosythesis occurs only in phototrophs. Photosythesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into ATP, and then release waste products.
Based on the description of DNA, given in the Do Now, what could be the nucleotide composition of a DNA double helix? 90 points 20% adenine, 20% guanine, 30% thymine, 30% cytosine 60% adenine, 20% thymine, 10% guanine, 10% cytosine 20% adenine, 20% thymine, 30% guanine, 30% cytosine 60% adenine, 20% guanine, 10% thymine, 10% cytosine
Answer:
20% adenine, 20% thymine, 30% guanine, 30% cytosine
Explanation:
Edwin Chargaff stated in his rule that, in a DNA molecule, the amount of purine bases (Adenine and Guanine) should equate the amount of pyrimidine bases (Cytosine and Thymine). Mathematically, this means that;
A + G + C + T = 100%
Where;
% Adenine base = % Thymine base
% Guanine base = % Cytosine base
Hence, according to this question, the DNA molecule described will contain
20% adenine = 20% thymine,
30% guanine = 30% cytosine
20% A + 20% T + 30% G + 30% C = 100%

Does Soil Affect Flower Color?

Garden Care
By
Mary Simpson
This flower must have grown in neutral soil, with little aluminum.
In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

Composes cellulose in trees and plants. 20. Main component of cell membranes 21. Provide a waterproof coating on leaves and feathers. 22. Composes chitin exoskeleton of insects. 23. Act as chemical messengers in the body.
Answer:
16. Carbohydrates
17. Lipids
18. Carbohydrates
19. Carbohydrates
20. Lipids
21. Lipids
22. Carbohydrates
23. Lipids
Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.
