Explanation:
Create a list of at least five expenses you would have to pay if you were going to raise a sheep for one year. You can assume that the land and the barn are available and focus just on the cost of raising a sheep. You do not need a dollar amount for the expenses; just identify what items should be included in the budget.
Answer:
Food, medication, rent of the land, doctor fee and cleaning.
Explanation:
The food, medication, rent of the land, doctor fee and cleaning are the expenses that I have to pay if I was going to raise a sheep for one year. Good feed is very important for raising an animal in order to get good products from that animal. Medication safes the animal from infection and other diseases that lowers the quality of that animal. I have to pay the rent of the land on which I raise that sheep and also pay doctor fee for their checkup.

Living things share many basic characteristics and needs. One characteristic is the need to maintain the internal conditions of their bodies, even if outside conditions change. Maintaining ___________ involves controlling the balance of water and minerals in the body, responding to changes in the environment, and controlling metabolism.
homeostasis
cellular organization
heredity
metabolism
Answer:
The answer is homeostasis.
Explanation:
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
Suppose you are given an unknown solution and you need to test its pH. The pH meter is broken, and all you have is the indicator bromothymol blue to use. You add two drops of bromothymol blue to 10 mL of your unknown, and the solution turns a bright yellow. Which of the following is the best estimate of the pH of the unknown solution?
a. 8.5
b. 11.5
c. 1.5
d. 7.0
Answer: The best estimate of the pH of the unknown solution is 1.5. Option C.
Explanation:
A substance which shows different colours in acidic and basic media is called an indicator. Typical examples of common indicators includes:
--> Litmus: colour in acid ( red), colour in base (blue) and colour in neutral (purple).
--> Methyl orange: Colour in acid (red), colour in base (yellow) and colour in neutral (Orange).
--> Phenolphthalein: Colour in acid (colourless), colour in base (pink) and colour in neutral (colourless).
--> BROMOTHYMOL BLUE: Colour in acid ( yellow), colour in base (blue) and colour in neutral (green).
The indicators are themselves weak organic acids or bases and hence slightly dissociated in solution. The colour of the indicator at any given point depends on the relative proportion of the dissociated ions to the undissociated molecules since they have different colours.
From the question, since the pH meter is broken, and the pH of the unknown solution is to be determined,using an indicator instead. The best estimate of the pH of the unknown solution is 1.5. This is so because BROMOTHYMOL BLUE is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and yellow when the pH is less than 6. And pH value of 1.5 is less than 6, indicating the solution is very acidic.

Answer:
B
Explanation:
Blood type is shown in the picture is B positive.
What do you mean by blood type?
"A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells."
What are the main blood types?
There are 4 main blood types or groups defined by the ABO system:
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma.blood group B – has B antigens with anti-A antibodies in the plasma.blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.blood group AB – has both A and B antigens, but no antibodies.

does coal releases carbon dioxide into the atmosphere?
Answer:
yes
Explanation:
Coal is an important source of energy in the United States, and the Nation's reliance on this fossil fuel for electricity generation is growing. The combustion of coal, however, adds a significant amount of carbon dioxide to the atmosphere per unit of heat energy, more than does the combustion of other fossil fuels

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.
a. True
b. False
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
Suppose you are a research assistant in a lab studying DNADNA-binding proteins. You have been given the amino acid sequences of all the proteins encoded by the genome of a certain species and have been asked to find candidate proteins that could bind DNADNA. What type of amino acids would you expect to see in the DNADNA-binding regions of such proteins
Answer:
The correct answer would be - Positively charged amino acid at pH 7 such as lysine, arginine, and histidine.
Explanation:
We know that DNA is a negatively charged molecule and proteins bind with them. This binding takes place between negative DNA molecules and positively charged amino acids of DNA binding protein.
Amino acids form hydrogen bonds with the nitrogen bases or phosphate groups of the DNA. Therefore, the DNA binding amino acid sequence should be of positively charged amino acids like lysine, arginine, and histidine at pH 7.

why does flowing water deposit the largest particles first
Answer:
Deposition by Water
Flowing water slows down when it reaches flatter land. ... The water starts dropping the particles it was carrying. As the water slows, it drops the largest particles first. The smallest particles settle last.
The Fitness of Water. For each of these statements about water, decide whether the statement is true and describes a property that makes water a desirable component of cells (T); is true but describes a property that has no bearing on water as a cellular constituent (X); or is false (F). For each true statement, indicate a possible benefit to living organisms.
a. Water is a polar molecule and hence an excellent solvent for polar compounds.
b. Water can be formed by the reduction of molecular oxygen O2.
c. The density of water is less thaan the density of ice.
d. The molecules of liquid water are extensively hydrogen-bonded to one another.
e. Water is odorless and tasteless.
f. Water has a high specific heat.
g. Water has a high heat of vaporization.
Answer:
A) True
The polarity of water is what makes it an ideal transport vehicle for nutrients and micronutrients that are water-soluble. Within organisms, water can be used to transport nutrients and even waste from one part of the body to the other. In the case of humans, urine is used to get rid of soluble waste from within the body.
B) True
During the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are taken from the air and soil respectively. Oxygen is able to produce water when it is reduced. Hydrogen during this process is oxidized.
C) False
Ice floats on water. Hence it cannot be denser than water. Rather, water is denser than Ice. Because of the structure of hydrogen bonds, when they are iced, the bonds tend to pull apart, thus making ice expand somewhat. This expansion creates microscopic pockets of air in the molecules thus given them buoyancy.
D) True (X)
E) True (X)
F) True
Heat Capacity refers to the amount of heat a substance like water can absorb before it's temperature rises by 1 degree. This property is important, because, were it not for the high specific heat capacity of water, many people and plants would have boiled over.
G True (X)
Heat of vaporization is the kind and amount of energy required to alter one gram of liquid into a gas at boiling point
