Many plant cells have more than two complete sets of chromosomes in each cell. Explain how this might occur.

Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.

Igestion of carbohydrates within the small intestine involves enzymes that come from the? a: mouth. b: stomach. c: pancreas. d:
ella [17]

Enzymes come from the pancreas.

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

The small intestine, not the stomach, is where carbohydrates are chemically broken down. The chemical breakdown of digestible carbohydrates is completed by disaccharidases and pancreatic amylase. The circulation carries the monosaccharides to the liver after absorption.

In 3-5 sentences write a description of how the 4 terms, DNA, chromosomes, genes and traits, are related and/or work together to
wel

Answer:

Please find the explanation below

Explanation:

Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.

The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.

Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.

What are some ways you think scientists can affect or utilize the genes of organisms?
aalyn [17]

Answer:

I'm not quite sure what your looking for

Explanation: scientists can take the genes of one successful crop, animal, etc, and insert that gene into future things so all offspring will be successful. This is called genetically modifying. Another thing scientists can utilize genes for is cloning. There have been ideals of the perfect human for many years and now scientists are trying to alter these genes to have perfect offspring according to your standards.
