Answer: D. About half of the offspring will have purple flowers, and about half of the offspring will
have white flowers,
Explanation: Purple flower is dominant over white flower, therefore a cross between Pw and ww will produce four offsprings, fifty percent of which will have purple flowers and the other fifty percent will have white flowers. The genotypes of the offsprings are Pw and ww. Pw will manifest outwardly as purple flowers while ww will manifest outwardly as white flowers.

Answer:
Covalent bonds appear inside every linear chain and connect bases, sugars, and phosphate groups.
Hydrogen bonds appear between two strands and involve the base from one strand with the base from another strand in the complementary pairing.
Explanation:
A covalent bond is a chemical bond formed by joining electrons of two non-metal atoms into one or more common pairs.
A hydrogen bond (X-bond) is a type of weak chemical bond based on electrostatic attraction between a hydrogen atom and a nucleophilic atom that contains free electron pairs.
(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts
Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
Antibodies protect our bodies from the invasion of foreign particles (pathogens)
Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
The statement best that explains why cells were observed in more detail using compound microscope than a simple microscope is : compound microscope has greater magnification ability than the simple microscope .
This will allow us to observe the subject with a much smaller size, making it easier for us to observe the detail
hope this helps
