Mendel carried out a dihybrid cross to examine the inheritance of the characteristics for seed color and seed shape. The dominan

t allele for yellow seed color is Y, and the recessive allele for green color is y. The dominant allele for round seeds is R, and the recessive allele for a wrinkled shape is r. The two plants that were crossed were F1 dihybrids RrYy. Identify the ratios of traits that Mendel observed in the F2 generation. Create a Punnett square to help you answer the question.

Hormones such as calcitonin, parathyroid hormone, and the pituitary hormones are protein-based and water-soluble. How does a hor
sashaice [31]

Answer: Substances that are protein based cannot cross the lipid cell membrane, but can exert their effect by binding to the proteins based receptors present on the lipid bilayer.

Explanation:

Hormones such as calcitonin , Parathyroid hormone and pituatry horomones are proteins and water soluble.They cannot cross lipid bilayer but can bind to ligand binding protein receptors.

These receptors are protein macromolecules that are specific in nature for specific hormones.

After binding to the receptors, these hormone-recpetor complexes activate second messengers and regulate the downstream effects.

In dna replication, each individual parent strand acts as a _____ strand for the synthesis of a _____ strand.
irina [24]
The answer is template strand; daughter strand.

<span>In DNA replication, each individual parent strand acts as a <u>template</u> strand for the synthesis of a <u>daughter</u> strand. DNA replication is a process of producing of two identical copies of DNA from the original DNA. DNA molecule consists of two strands and each strand serves as a template strand for the synthesis of a daughter cell. DNA polymerase binds to the origins of replication and synthesises daughter strands by adding complementary nucleotides.</span>

A group of cells is assayed for DNA content immediately following mitosis (G1) and is found to have an average of 8 picograms of
mariarad [96]

Answer:

16 pg at the end of S

16 pg at the end of G2

Explanation:

A cell has 8 pg of DNA per nucleus in G1.

During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.

During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.
