Answer:
He would need to cross one homzygous red (RR) and homzygous white (rr)
Explanation:
Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.
According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.

O C. Nucleic acids are made of repeating units called lipids.
O D. Nucleic acids store important information about cell division and the manufacturing of proteins and genetic information.
Answer:
D
Explanation:
nucleic acids( DNA &RNA). the DNA contains the genetic information of an organism while some RNA are used as messager within the cell. mRNA is usually sent to the nuclueoi to synthesis ribosomes, and ribosomes is the site of protein production in the cell.

The bar graph that is essential to answer the question is attached with the answer:
Answer:
The correct answer is given as follows:
Explanation:
Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.
In this case: 37 is the mean value that can be calculated by:
adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259
Number of sets = 7
then mean = 259/7
= 37
Thus, the mean can be calculated by total value divided by the number of sets

explain reproduction in hydra
Answer:
Budding
Explanation:
The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent. Buds are produced every two to three days under favorable conditions. Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.

What types of reactions are catalyzed by enzymes?
A. Hydrolysis
B. Dehydration Synthesis (also known as Condensation)
C. All of these
D. Other types of reactions
Answer:
is B. Dehydration synthesis
Explanation:
I hope this helps
The types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation. Thus, option B is correct.
What is dehydration synthesis?
When the level of water has been decreased the phenomenon has been known as the dehydration and the types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation.
Enzymes has been known as the biological catalyst that has been speed up the chemical reaction that use to carries out in the body. Enzymes are the protein by the nature and there are number of the enzymes present in our body such as the salivary amylase, pepsin, renin, lyases, lygases etc
The main function of the enzyme has to make the metabolism fast as well as speed up the chemical reaction carried out in the body. The best example of the enzyme has been salivary amylase which has an enzyme and it is present in the saliva and helps in the digestion of food.
Therefore, The types of reactions are catalyzed by enzymes which is also known as dehydration Synthesis as condensation. Thus, option B is correct.
