In-s [12.5K]

Answer: genotype: Ee phenotype: two small eyes.

genotype: RR'  phenotype: pink eyes

genotype: GB phenotype: green and blue splotches

genotype: cc phenotype:  straight

genotype: Tt phenotype:  has tail

genotype: Ss phenotype: sharp teeth

genotype: FF' phenotype: three toes

genotype: ww phenotype: white

genotype: YY phenotype: pointy

genotype: nn phenotype: two ears

genotype: Ll phenotype: long

Explanation: hope this helps (the uppercase letters are dominant genes. the lowercase letter are recessive genes. for a recessive gene to show up in a phenotype you need 2 lower case letters such as cc or ss. for a dominant gene to show up in phenotype you need either 1 or 2 uppercase letters such as Cc or SS. Codominant genes present both colors in the phenotypes i.e. a brown and white cow. incomplete dominance is when neither gene is dominant so a mix of the 2 are present in the phenotype i.e. a pink rose. A regulatory gene controls the expression of a gene

Write the molecular formula for a compound with the possible elements C, H, N and O that exhibits a molecular ion at M
liberstina [14]

Answer:

= \mathbf{C_3H_6O}

Explanation:

From the given information, since the molecular mass of the ion M+ is not given;

Let's assume M+ = 58.0423

So, by applying the 13th rule;

we will need to divide the mass by 13, after dividing it;

The quotient n = no. of carbon; &

The addition of the quotient (n) with the remainder r =  no. of hydrogen.

So;

\dfrac{58}{13}= 4 \ remainder \ 6

So;

C_nH_{n+r} = C_4H_{4+6}

= C_4H_{10}

From the given information; we have oxygen present, so since the mass of oxygen = 16, we put oxygen in the molecular formula by removing CH_4. Also, since the mass is an even number then Nitrogen is 0.

So, we have:

= \mathbf{C_3H_6O}

How much heat do you need to raise the temperature of 150 g of ice from -30°C to -15°c?
OLga [1]
To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.

How does positive catalyst increase the rate of chemical reaction?​
KATRIN_1 [288]

Answer:

A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction. ... Remember that with a catalyst, the average kinetic energy of the molecules remains the same but the required energy decreases

Explanation:

...

hope that is helpful
