How did Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach?
Answers
Absorption of the nutrients will not happen in her small intestine.
Claire’s digestion reaction rates tell you that the problem was in her small intestine, and not her stomach because the intestine is responsible for the absorption of most of the nutrients produced from eating and drinking of food substances.
If the absorption of the nutrients will not happen by the intestine, the whole homeostasis or equilibrium of the body disturbs and no growth of the cell occurs so we can conclude that absorption of the nutrients will not happen in her small intestine.

Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow the largest tomatoes. She plants tomato seeds in 4 different pots and leaves one pot in the dark. She gives 6 hours of light a day to the second, 8 hours of light a day to the third, and 10 hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. Match up each variable in the experiment. Group of answer choices Independent varible [ Choose ] Dependent variable [ Choose ] Control variable [ Choose ] Control group [ Choose ]
Answers
Answer:
The correct answer is -
Independent variable - the amount (time period) of light given to pots.
Dependent variable - size of tomatoes
Control variable - dark or absence of light
Control group - pot placed in the darkroom.
Explanation:
The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.
The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.
The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.
The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.

Having straight ears (E) is dominant over droopy ears (e). A parent with straight ears is crossed with a parent with droopy ears. The Punnett square will show the possible genotypes of the offspring. What is the genotype of each square?
A: EE, Ee, ee
B: EE, Ee, ee
C: EE, Ee, ee
D: EE, Ee, ee
Answers
Answer:
Ee Ee ee ee 50/50 on having either droopy ears or straight
Explanation:
The genotype of square A is Ee, square B is ee, square C is Ee, and square D is ee.
What are genotypes?Genotypes are the genetic makeup or the complete set of genes that an individual organism possesses. They are responsible for determining an organism's physical and behavioral traits.
The genotype of an organism is encoded in its DNA, which consists of long sequences of nucleotides that code for specific proteins and other functional molecules. These nucleotide sequences are organized into genes, which are located on chromosomes in the nucleus of the cell.
Genotypes can be inherited from parents and passed down to offspring through sexual reproduction. However, mutations and genetic variations can also occur spontaneously, leading to changes in an individual's genotype.
