Mendel crossed the dominant smooth seeded pea plant (SS) with the recessive wrinkled seeded pea plant (ss). The F 1 generation produced the heterozygous smooth seeded plants with a genotype Ss. When two heterozygous pea plants (Ss) are crossed in the F2 generation represented by Ss x Ss, the gametes formed are S and s. In the second generation, out of the total offspring produced, 3 have the smooth seeded phenotype and 1 has wrinkled seed phenotype. Thus the phenotypic ratio is 3: 1 with one out of four plants being a wrinkled seeded pea plant.
Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!
Answer:
TGGCAATCG
Explanation:
Remember:
Adenine always pairs up with either Uracil (RNA) or Thymine (DNA)
Cytosine always pairs up with Guanine (Both DNA and RNA)
i think is
The predators’ survival depends on biotic factors.
There are many facts about arachnids.
Here are some:
1. Arachnids are invertibrates (No backbone)
2. Arachnids include spiders, mites, harvestmen, and pseudoscorpions.
The scientific name is Arachnida, and the higher classification name is Chelicerata.
