Answer:
False
Explanation:
You are interested in tracking a particular trait. To begin your studies you do a dihybrid self cross. What percentage of the offspring will be dihybrids themselves
Answer:
4/16 (i.e. 25%)
Explanation:
A dihybrid cross is a cross between two organisms/lines/genes that are hybrids (i.e., heterozygous) for two different traits. In a standard dihybrid cross, there is a relation of complete dominance for both loci, i.e., there are two alleles that are completely dominant and thus mask the effects of the corresponding recessive traits. In a dihybrid cross involving two different genes that assort independently into gametes during meiosis, with dominant alleles "A" and "B" and recessive alleles "a" and "b", respectively, the expected phenotypic ratio will be 9:3:3:1 (ie. 9/16 A_B_, 3/16 A_bb, 3/16 aaB_ and 1/16 aabb), while the expected genotypic ratio of double heterozygous "AaBb" individuals will be 4/16, i.e. 25%.
Representation:
P generation >> AaBb (father) X AaBb (mother)
Gametes (for both parents) >> 1/4 AB; 1/4 Ab; 1/4 aB; 1/4 ab
F1 generation >> 1/16 AABB; 2/16 AABb; 2/16 AaBB; 4/16 AaBb; 1/16 AAbb; 2/16 Aabb; 1/16 aaBB; 2/16 aaBb; 1/16 aabb
For the Hill Reaction, you used DCIP dye at a concentration of 1x10-4 M. Our lab technicians have stock solution at a concentration of 100mM. Explain how you would make 100mL of the DCIP for you to use in a Hill Reaction lab.
Answer:
by diluting the DCIP dye stock solution 1000 times. It can be done by diluting 0.1 ml of the DCIP dye stock solution with 99.9 ml of distilled water
Explanation:
1 millimolar (mM) = 0.001 M
1.0 × 10⁻⁴ Molar (M) = 0.0001 M = 0.1 mM
Stock solution = 100 mM = 0.1 M
100 mM DCIP dye solution diluited 1000 times >> 0.1 mM = 1 x 10⁻⁴ M
Analyze Can relative humidity be more
than 100 percent? Explain your answer.
Answer:
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.
Explanation:
All organisms are genetically different.
All organisms have homologous structures.
All organisms share a common genetic code.
All organisms came from different ancestors.
Answer:
All organisms share a common genetic code.
Explanation:
Organisms are genetically different for the most part but this asks why it applies to all organisms.
They do not all have homologous structures
They share a common ancestor

What can you conclude about the structure of mitochondria?
Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate
Explanation:
hope that helped ;/
Answer:
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae
HAIR ANALYSIS
An investigator is excited to find a hair with the follicle attached when searching for evidence at a crime scene. Explain why the investigator might be excited.
The fact they hair follicles contains cellular materials rich in DNA will give them a strong lead in their investigation. Hence, the excitement.
The bottom of the hair follicle marks the point where hair growth begins, Investigators are often helped in their crime research by the outcome of DNA test. Therefore, investigators often seek materials or elements at crime scenes which could be evaluated to gives DNA result of potential suspects.Therefore, the fact that hair follicles contain cellular materials which are rich in DNA, will excite investigators as that have obtained a key lead in their investigation.
