In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p). Stem length is control

led by another pair of alleles where tall (T) is dominant to short (t). These two allele pairs segregate independently. Suppose you have a pea plant that has purple flowers and tall stems and you wish to carry out a testcross in order to determine its genotype. Complete the predictions using the correct terms.
In order to carry out the testcross, you should cross your original pea plant with another pea plant whose phenotype is ___________

Answer:

white flowers and short stem

Explanation:

A test cross is performed usually to find out the genotype of a dominant phenotype because it can be homozygous or heterozygous. To perform the test cross, the test organism is mated with the recessive phenotype organism. Here, plant having white flowers and short stem (pptt) will be used in test cross. Few examples of test cross results are as follows:

If the original dominant phenotype plant is homozygous for both traits, all the offspring in the next generation will have dominant phenotype:

PPTT X pptt =

        pt

PT  PpTt

If the plant is heterozygous for both traits, four types of offspring will be produced:

PpTt X pptt =

       pt

PT  PpTt

Pt   Pptt

pT  ppTt

pt   pptt

Hence varying results after a test cross can help to determine the genotype of the original plant.

KATRIN_1 [288]

The correct answer fro above statement is:

<h3> c. Half of all rainforest plants have been tested for their medicinal properties.</h3><h3>Explanation:</h3>

Twenty-five percent of the fresh components in cancer medications are particularly rainforest plants.Rainforests are essential because they serve control global climate trims and rain. Water that disappears from trees comes in other regions as rain.Twenty-five percent of Western pharmaceuticals are obtained from rainforest components. But since only a minute portion of rainforest organisms have been investigated, as the rainforest species escape so do possible remedies and therapies for life-threatening disorders.

Why are enzymes specific to a certain reaction?
frozen [14]
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. ... The enzyme's active site binds to the substrate.

What is the role of a lipid molecule, which atoms make up most lipids, how does the lipids structure relate to its function.
Alisiya [41]

Answer and explanation;

-All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. Fats are triglycerides.

-The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.

-Lipids are water-insoluble (hydrophobic), and this property is put to great use in the organisation of cells and tissues.

For example; phospholipids are a class of lipids that is amphipathic; that is it contains fatty acid tails that are hydrophobic, and a phosphate head that is hydrophilic. This means the phosphate group will orientate itself towards water and away from the rest of the molecule, and also gives rise to the special properties that allow phospholipids to be used to form membranes.
