A scientist crossed a tall pea plant with a short pea plant. Of the offspring, 13 were tall and 12 were short, write the ratio of each phenotype to the total number of offspring. Express the ratios as fractions
Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%

6
Explanation:
In all three stages of cellular respiration combined, as many as 36 molecules of ATP are produced from just one molecule of glucose.
what do chromosomes store?
Answer:
A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA and protein molecules required by an organism.

A population of antelope lives on the African Savannah and is hunted by lions. Explain how a mutation that allows some antelope to run faster than others might lead to the evolution of this population . *
3 points
Your answer
Answer:
The individual carrying this beneficial mutation will be selected through natural selection.
Explanation:
Mutations are genetic changes in the DNA sequence. When mutations occur in the germline, these genetic modifications can pass from one generation to the next. In general, mutations are deleterious, but there are exceptions where they may be beneficial for the individual and provide the raw material for evolutionary change. An individual carrying one beneficial mutation will have more chances to survive and reproduce than individuals without this mutation, and thereby such genetic change will increase its frequency in the population.

which part of the amino acid most likely contributes to the hydrophobic behavior if this region in the polypeptide
Answer:
This question is incomplete
Explanation:
This question is incomplete, however, the side chain is usually the part of an amino acid that is either hydrophilic or hydrophobic in nature. When the side chain has little or no polarity (i.e they lack the ability to interact with highly polar water molecules), the amino acid exhibits hydrophobic properties. Hydrophobic (water-fearing) substances are substances that do not interact/dissolve in water.

Which letter marks the location where carbon dioxide is
produced during respiration?
OW
ОХ
Ο Υ
Ο Ζ
Letter X represents the Mitochondria which marks the location where carbon dioxide is produced during respiration. So, the correct option is B.
What is Mitochondria?A mitochondrion is defined as an organelle which is found in the cells of most eukaryotes, such as animals, plants, and fungi that have a double membrane structure. It uses aerobic respiration to generate adenosine triphosphate, which is used throughout the cell as a source of chemical energy.
The main role of mitochondria is oxidative phosphorylation which utilizes the energy released during the oxidation of the food we eat to generate ATP which is used as the primary energy source for most biochemical and physiological processes such as growth, movement and homeostasis.
So, the correct option is B.

Secondly there is 2 option for Dominant one
It could be Ss or SS so if you wanna know what is what you need to use recessive gen
S- ss if all genes are hybrid dominant one would be SS if some genes aren’t hybrid dominant one would be Ss
