Answer:
B. carbon dioxide and water
Explanation:
Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.
The equation for cellular respiration is:
glucose + oxygen —> ATP + carbon dioxide + water
The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.
Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.
Answer:
B. water and carbon dioxide
This problem leads you through the derivation of a corrected equation for RF in yeast tetrad analysis that takes into account double crossover (DCO) meioses. A yeast strain that cannot grow in the absence of the amino acid histidine (his−) is mated with a yeast strain that cannot grow in the absence of the amino acid lysine (lys−). Among the 400 unordered tetrads resulting from this mating, 233 were PD, 11 were NPD, and 156 were T.
a. What types of spores are in the PD, NPD, and T tetrads?
b. Are the his and lys genes linked? How do you know?
c. Using the simple equation RF = 100 × [NPD +(1/2)T]/total tetrads, calculate the distance in mapunits between the his and lys genes.
d. If you think about all the kinds of meiotic eventsthat could occur (refer to Fig. 5.24), you can see that the calculation you did in part (c) may substantially underestimate RF. What kinds of meioses (NCO, SCO, or DCO) generated each of the tetrad types in this cross?
e. What incorrect assumptions does the simple RFequation you used in part (c) make about themeiotic events producing each type of tetrad? Whencould these assumptions nevertheless be correct?
f. Use your answers to part (d) to determine thenumber of NCO, SCO, and DCO meioses thatgenerated the 400 tetrads.
g. Use your answers to part (f) to write a generalequation that relates the number of DCO meiosesto the number of the various tetrad types. Thenwrite another general equation that computes thenumber of SCO meioses as a function of the number of the various tetrad types.
h. Based on your answer to part (f), calculate theaverage number of crossovers per meiosis (m)between his and lys.
i. Use your answer to (h) to write an equation for min terms of NCO, SCO, and DCO meioses.
j. What is the relationship between RF and m?
k. Use your answer to part (j) to write a corrected equation for RF in terms of SCO, DCO, and NCO meioses. l. Using your answer to part (g), rewrite the corrected RF equation from part (k) in terms of the numbersof the various tetrad types.
m. The equation you just wrote in part (l) is a corrected equation for RF that takes into account doublecrossovers that would otherwise have been missed. Use this improved formula to calculate a moreaccurate distance between the his and lys genes than the one you calculated in part (c).

Explanation:
right auricle is bigger than left auricle why
Explanation:
Veins carry deoxygenated blood from different parts of the body to our heart. ... Since a larger volume of blood is collected in the right auricle than that of the left auricle, right auricle is larger than the left auricle.

Which two atoms form a covalent bond?
A. A sodium and chlorine atom
B. Two oxygen atoms
C. Two sodium atoms

Respiration occurs in the__________
1 nasal cavity
2 lungs
3 red blood cells
4 cells of the body
Answer:
cells of the body
Explanation:
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing

A component of the cell that collects freshly generated proteins and other materials from the endoplasmic reticulum wraps them, and transports them to other areas of the cell is called the Golgi apparatus. The correct option is B.
What is the Golgi apparatus?Golgi apparatus is an organ of the eukaryotic cells. It is an irregular-shaped organ. It was discovered by Camillo Golgi. That's why its name is Golgi apparatus.
There are many functions of this organ. It helps in the packaging of proteins and lipids molecules. These proteins are then transported to other parts of the cell.

What is a good property of an indicator?
Answer:
Acid base indicators are weak and acids and bases, which are used to signify the end point of neutralization reaction. The type of indicator used for a neutralization reaction depends on the strength of the acid and the base, that are involved in the reaction. A good acid base indicator must have a good pH range and it must be able to produce specific and identifiable color in specific acid base medium.
or
Two good properties of an indicator are as follows-
1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.
2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.
Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.

In roses, red flowers and long stems are dominant traits. A rose plant that is homozygous for both red flowers and long stems is
crossed with a rose plant that is heterozygous for red flowers and homozygous for short stems. What percentage of the offspring
will exhibit red, long-stemmed flowers?
25 percent
O 50 percent
O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.
