Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Genes are segments of DNA that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

The term chromosome comes from the Greek words for colour (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colourful dyes used in research. The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones.

Without such packaging, DNA molecules would be too long to fit inside cells.

Answer:

3,381 grams

Explanation:

The problem can be solved by using the formula for "Density." The formula for density is: Density (ρ) = [tex]\frac{mass}{Volume}[/tex]

Now that we know the formula, we can get the formula for the "mass."

The given density above is 23 g/mL while the given volume is 147 mL. We have the values of the density and volume, thus, it is easy to solve the problem.

Let's solve.

The mass of the meteorite is 3,381 grams.

Answer:

a glass of muddy water

Explanation:

Pure substances contain only one element or compound.

Calcium is one element so it is a pure substance. Ice and water have the same molecular structure, so it is a pure substance. Aluminum oxide is a chemically pure compound.

The only example that is not a pure substance is muddy water due to the multiple components of mud mixing with the components of water.

E.e. platensis

E.e. xanthoptica

E.e. croceater

E.e. eschscholtzii

E.e. klaubori

Explanation:

The species mentioned above are probably separate species from E.e. eschscholtzii. this separation occurred due to geographic isolation, where each group of E.e. eschscholtzii evolved creating new species. This type of speciation is called "ring species" and refers to an evolution that is capable of providing species with extremes of variation that are not intercrossed, due to geographic isolation.

The ABO blood classification is based on antigen on the red blood cell. Therefore, option (C) is correct.

Based on the presence or absence of antibodies and antigenic substances on the surface of red blood cells, a blood type is a classification of blood.

A framework used to human blood into various kinds, in view of the presence of specific on the outer layer of platelets. A, B, O, and AB are the four blood ABO types.

When there are more than two possible alleles for a single chromosomal locus, this is called a multiple allele. The ABO blood bunch is an exemplary illustration of this. Each person has two alleles for the ABO blood type because they have two number 9 chromosomes.

Answer:

Traits are determined by genes. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins.

Answer:

A. temperature of the reaction

B. amount of enzyme

E. pH of the reaction

Explanation:

Temperature should be kept constant because enzymes operate at different activity rates depending on the temperature. The same goes for the pH as well with different enzymes having different optimal pH levels.

The amount of enzyme should be kept constant as well because different concentrations of enzymes can determine how fast the reaction will occur.

Essentially anything that could affect enzyme activity apart from substrate concentration should be kept constant.

Answer:

Please find the summary of what happens during DNA replication below

Explanation:

DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:

- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.

- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.

- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.

- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.

After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

Answer:

Golgi apparatus, because it packages proteins received from the ER

Explanation:

The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.

The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.

If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.

Hope that helps.

If the endoplasmic reticulum (ER) were removed from the cell, Golgi apparatus would not be able to function properly.

Hence, Golgi apparatus would not function properly if Endoplasmic Reticulum is removed.

CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.

Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.

The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.
