In guinea pigs, short fur (S) is dominant to long fur (s). Two heterozygous guinea pigs
(Ss) mate. Complete the Punnett square and then list the percentages of the
expected genotypes for their offspring.
Answers
Explanation:
A way I like to remember heterozygous is by remembering that the other word for heterozygous because brainly wont let me say it apparently. The same gender liking each other, so (word) is same, hetero is different.
each square would have 25% each because 100%÷4=25.
Dominant one is like mixing black and blue together,the black is gonna give a dark effect to blue so black is dominant.
Blue is recessive.
The percentage of the Ss is 75% while the percentage of the ss is only 25%.
Performing a crossGiven that we have the genotypes of the both parents as Ss. The Ss imples that the gene for short fur is dominant over the gene for long fur.
Now, when we perform te cross for the first generation, we will discover that we have the offspring; Ss, Ss, Ss and ss. The percentage of the Ss is 75% while the percentage of the ss is only 25%.

Explanation:
Photosynthesis and cellular respiration both are opposite to each other because the reactants of photosynthesis are the products of respiration whereas the reactant of respiration are the products of photosynthesis.

10+6h=34 what does h equal?
Answers
Answer: h = 2.125
Explanation:
Simplifying
10h + 6h = 34
Combine like terms: 10h + 6h = 16h
16h = 34
Solving
16h = 34
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '16'.
h = 2.125
Simplifying
h = 2.125Answer:
The answer is h = 4.
Explanation:
1) Subtract 10 from both sides.
[tex]6h = 34 - 10[/tex]
2) Simplify 34 - 10 to 24.
[tex]6h = 24[/tex]
3) Divide both sides by 6.
[tex]h = \frac{24}{6} [/tex]
4) Simplify 24/6 to 4.
[tex]h = 4[/tex]
therefor, the answer is h = 4.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
a Phenylalanine, serine, leucine
b Serine, alanine, leucine
C Methionine, serine, leucine
d None of the above
Answers
Answer:
A A U C C
A AAA Lysine AUA ACA Threonine
A AAU Asparagine AUU ACU Threonine
A AAC Asparagine AUC ACC Threonine
The codon UUC encodes for the amino acid phenylalanine, the codon UCU encodes serine, and the codon CUU encodes leucine. So the correct answer is (a).
Organic substances known as amino acids have both amino and carboxylic acid functional groups. Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life.
A collection of instructions called the genetic code governs how DNA is converted into proteins. Codons, which are three-nucleotide sequences, are the building blocks of the code. Codons each represent each individual amino acid.
The codons UUC, UCU, and CUU all code for the amino acid phenylalanine. The third nucleotide in the codon determines the amino acid that is encoded. The codons UUA and UUG has different nucleotide from phenylalanine in the third position and thus code for leucine. The codon UCG encode for Serine.
Therefore, option (a) is right.

Which characteristic do all protists have?
They all make or consume food.
They all survive in any environment.
They are all unicellular.
They all have flagella.
Answers
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.

Which of the four factors that affect evolution apply to the finches that the Grants studied? Use
evidence from your research to support your answer. (15 points)
Answers
Answer:
Natural Selection in Real Time
"When we made the comparison between the size of the offspring generation and the population before selection, we found a measured, evolutionary response had taken place and it was almost identical to what we had predicted."
-Peter Grant
Darwin thought that evolution took place over hundreds or thousands of years and was impossible to witness in a human lifetime. Peter and Rosemary Grant have seen evolution happen over the course of just two years.
The Grants study the evolution of Darwin's finches on the Galapagos Islands. The birds have been named for Darwin, in part, because he later theorized that the 13 distinct species were all descendants of a common ancestor. Each species eats a different type of food and has unique characteristics developed through evolution. For example, the cactus finch has a long beak that reaches into blossoms, the ground finch has a short beak adapted for eating seeds buried under the soil, and the tree finch has a parrot-shaped beak suited for stripping bark to find insects.
The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.
The first event that the Grants saw affect the food supply was a drought that occurred in 1977. For 551 days the islands received no rain. Plants withered and finches grew hungry. The tiny seeds the medium ground finches were accustomed to eating grew scarce. Medium ground finches with larger beaks could take advantage of alternate food sources because they could crack open larger seeds. The smaller-beaked birds couldn't do this, so they died of starvation.
In 1978 the Grants returned to Daphne Major to document the effect of the drought on the next generation of medium ground finches. They measured the offspring and compared their beak size to that of the previous (pre-drought) generations. They found the offsprings' beaks to be 3 to 4% larger than their grandparents'. The Grants had documented natural selection in action.
While beak size is clearly related to feeding strategies, it is also related to reproduction. Female finches tend to mate with males that have the same size beaks. These factors together can add to the development of new species.
The Grants return each year to Daphne Major to observe and measure finches. They have been collecting data on the finches for over 25 years and have witnessed natural selection operating in different ways under different circumstances.

Which of the following is true about molecules?
1. Composed of the two same atoms
2. Composed of two different atoms
3. H2O is an example of molecule
4. All of the above is true.
Answers
Answer:
4) All of the above is true.
Why?
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom. This is written as H2O.
