What roles do DNA and chromosomes play in the coding of instructions for the inheritance of traits, or joe traits passed on parents to offspring?
Answer:
I really hope this helps
DNA is the vital for all living beings. even plants. it is important for inheritance, coding for proteins and the genetic instruction guide for life and its processes. DNA holds the instructions for an organisms or each cells development and reproduction and ultimately death.
Each chromosome consists of a single, very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. the instructions for forming species characteristics are carried in DNA.

Answer:
Proteins
Explanation:
Enzymes are an example of a class of organic compounds called proteins.
PROTEINS:
Proteins are one of the four major biological molecules in nature (others being carbohydrates, lipids and nucleic acids). Proteins play vital roles in living organisms, which includes regulating biochemical reactions, repair of structures etc. Enzymes are biological catalysts that helps to regulate the rate of a reaction. Enzymes are proteinous in nature i.e. they are made of proteins.

A student observes that a popcorn kernel has a hard coat. He places the kernel in a moist paper towel and observes it for several days. He notices that the coat splits and a small root emerges. He concludes that—
water outside the seed coat exerted a pushing force, breaking the seed coat
air inside the seed coat exerted a pushing force, breaking the seed.
water outside the seed coat exerted a pulling force, breaking the seed coat.
gravity exerted a pulling force on the stem, breaking the seed coat.

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

which kind of electrical charge is found on a hydrogen atom of a polar water molcule?
Answer:
he two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water's properties of attraction
Explanation:
Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

What do codons in DNA code for?
Answer:
mRNA and then amino acids
Explanation:
Codons are triplets (3) bases that code for defined amino acid sequences.
DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.
Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.

List the 3 reasons why mitosis occurs
Mitosis is a cell division method a part of the cell cycle that is essential for growth and development, repair and replacement, and asexual reproduction.
What is mitosis?Mitosis is a type of cell division method that occurs in all the somatic cells and plays a crucial role in living organisms. They produce daughter cells to increase the cell number and to aid in the growth and development.
They replace and repair the damaged cells in the body and also is a form of asexual reproduction where the parent cell is divided to form a new daughter cell with the same ploidy.
Therefore, mitosis is essential for growth, repair, and asexual reproduction.
