Assume that a dihybrid cross is made in which the two genes are autosomal and independently assorting. each gene has two alleles

which show incomplete dominance. how many different phenotypes would be expected in the offspring?

There will be nine (9) different phenotype would be expected in the offspring. E<span>ach gene is incompletely dominant each possible genotype would be a distinct phenotype. There should be 9 distinct phenotypes (one per distinct genotypes). Note there are 4^2 = 16 possible genotypes, however, some repeat for phenotypical expression. </span>

leva [86]

Answer:

Each is a mini-ecosystems and a representation of much larger ecosystems found on earth. The mini ecosystem is the terrarium

Explanation:

A terrarium is the accumulation of small plants that are being grown in the transparent, or sealed container. It is a closed environment type and are mostly used to know how the ecosystem works within itself. Inside that small container, we can observe various natural processes like photosynthesis, respiration, as well as water cycle. Some small plants cannot adapt well in the home environment, so they can be grown in the terrarium. If they are properly planted and taken care of they can grow with minimum care. By this we can grow indoor plants with less care.

hjlf

Options missing:

a) The pH of the environment should be relatively high.

b) The pH of the environment should be relatively low.

c) The pH of the environment would not matter.

d) The environment should be set to the biochemical standard state.

Answer:

a) The pH of the environment should be relatively high.

Explanation:

For optimal function an enzyme needs a certain environment or condition. As temperature increases, the rate of enzyme activity also increases. As temperature increases toward its optimum point of 37 degrees Celsius (98.6 F), hydrogen bonds relax and make it easier for the hydrogen peroxide molecules to bind to the catalase.

The part of the enzyme where this reaction takes place is called the active site. A temperature that is higher or lower than this optimum point changes the shape of the active site and stops the enzyme from working. This process is called denaturation.

Enzyme pH levels also change the shape of the active site and affect the rate of enzyme activity. Each enzyme has its own optimal range of pH in which it works most effectively. In humans, catalase works only between pH 7 and pH 11. If the pH level is lower than 7 or higher than 11, the enzyme becomes denaturated and loses its structure. The liver sustains a neutral pH of about 7, which creates the best environment for catalase and other enzymes.

General acid catalysis would require histidine to be protonated at pH values (pH 8.0) optimal for enzymatic activity which is relatively high.

Denzel's mom has asked him to organize the family's trash for disposal. Which of these items should he put with the hazardous wa
hjlf
The answer would be used batteries. You would be able to recycle the vegetable waste within fertilizing and/or throw it away safely by disposing it in a trashcan since it is not a hazard towards the environment. As for aluminum cans, they are recyclable and are easy to use again once it is filtered through the system. However, batteries are NOT recyclable nor easy to dispose because they can release Alkaline which can harm the environment.

Predict how many genetically different offspring could be produced by outcrossing two 2n=4 individuals (just account for indepen
Llana [10]

Answer:

16 genetically different offspring

Explanation:

This is the case as each parent has the ability to produce 4 uniquely different gametes through independent assortment. With such a scenario where each parent can product 4 uniquely different gametes multiplied by 4 parents, you have 16 offspring. So there's the possibility of producing 16 offspring that are unique.
