For summer squash, the dominant allele Y for gene 1 leads to yellow color while the recessive allele y leads to green color. Alleles of gene 2 can prevent color formation, with the dominant allele W leading to white squash while the recessive allele w does not interfere with color development. How many phenotypes would be observed among the offspring of the following cross: YyWw x YyWw

Answers

Answer 1

Answer:

Three phenotypes:

12/16 individuals are expected to be white3/16 individuals are expected to be yellow1/16 individual is expected to be green

Explanation:

Available data:

Gene 1 → Dominant allele Y ⇒ yellow

                        Recessive allele y ⇒ green

Gene 2 → Dominant allele W ⇒ prevent color ⇒ White

                         Recessive allele w ⇒ Does not prevent color

Cross:

Parentals) YyWw        x     YyWw

Gametes) YW, Yw, yW, yw

                 YW, Yw, yW, yw

Punnett square)     YW          Yw           yW           yw

                YW      YYWW    YYWw     YyWW      YyWw

                 Yw      YYWw     YYww      YyWw      Yyww

                 yW      YyWW     YyWw      yyWW      yyWw

                 yw       YyWw      Yyww      yyWw      yyww

F1) Genotype

1/16 YYWW2/16 YYWw1/16 YYww2/16 YyWW4/16 YyWw2/16 Yyww1/16 yyWW2/16 yyWw1/16 yyww

    Phenotype

12/16 white individuals ⇒ Y-W-, yyW- (Dominant W allele is present, inhibiting the expression of color)3/16 yellow individuals ⇒ Y-ww (Dominant W allele is absent, so color can be expressed. Y allele determinates yellow color)1/16 green individuals ⇒ yyww (Dominant allele W is absent, so color can be expressed. Only y alleles are presents coding for green color)

Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size

Answers

Answer:

The correct answer is ''the total amount of energy an animal uses in a unit of time''

Explanation:

The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.

What are the waste products of alcoholic fermentation?

Answers

Answer:

ethanol and carbon dioxide :)

Explanation:

The correct option is A. Ethanol and carbon dioxide are the waste products of alcoholic fermentation.

What is alcoholic fermentation?

A biological process called alcoholic fermentation, often known as ethanol fermentation, turns sugar into alcohol and carbon dioxide. Alcoholic fermentation is an anaerobic process since yeasts carry out this function and oxygen is not required.

The fermentation process produces heat, carbon dioxide, water, and alcohol as byproducts. In this instance, our attention is on the latter.

Which definition is the best for “semipermeable membrane

Answers

Answer: A semi-permeable membrane is that which only allows certain

               substances to pass through.

Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.
