The next steps the scientists should take to determine the exact difference is that they should look at the sequence of genes in the DNA bases for that trait.
Genes- The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. Many genes do not, however, code for proteins. The few thousand DNA bases to even more over 2 million bases make up a gene in a human.
DNA- The information molecule is DNA. It contains information needed to create proteins, which are other big molecules. These instructions are dispersed throughout 46 lengthy structures called chromosomes that are found inside each of our cells. Numerous smaller pieces of DNA, known as genes, make up these chromosomes.

explain the role of biotechnology in agriculture?
Biotechnology, at its most basic, is biology-based technology; biotechnology harnesses cellular and biomolecular processes to develop technologies and products that improve our lives and the health of our planet. The primary goal of modern biotechnology in agriculture is to improve the quality, quantity, nutrition, taste, and shelf life of produce, allowing stakeholders to achieve higher yield with lower energy costs.
This includes ancient agricultural processes such as fermentation as well as more recent examples of developing disease-resistant plant varieties through crossbreeding. Modern methods for improving agricultural practices through biotechnological progress include transgenic techniques, which revolve around the insertion of foreign DNA strands into the host genome to increase crop yield.
Agriculture biotechnology benefits include increased crop yield, reduced crop vulnerability to environmental stresses, improved nutritional qualities of food crops, improved taste, texture, or appearance of food, and reduced reliance on fertilizers, pesticides, and other agrochemicals.

prophase of meiosis i has some important differences from prophase of mitosis. these differences include: ______ pair, and ______ occurs.
The prophase of meiosis I have a few essential variations from the prophase of mitosis. those differences include Homologous chromosomes pair, and crossing over takes place.
Mitosis is the department of frame cells and meiosis is the division of the sex cells or gametes-producing cells.
Mitosis is a process wherein a single cell divides into identical daughter cells. Whereas Meiosis is a technique in which a single cell divides twice to produce 4 cells containing 1/2 the initial quantity of genetic materials.
Meiosis I, the primary meiotic division, begins with prophase I. For the duration of prophase I, the complex of DNA and protein referred to as chromatin condenses to shape chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at the center known as the centromere.
Prophase is the primary segment of mitosis, the manner that separates the duplicated genetic material carried within the nucleus of a discern cell into identical daughter cells. During prophase, the complex of DNA and proteins contained inside the nucleus referred to as chromatin condenses.

If you took a linear piece of DNA and cut it with the restriction enzyme EcoRI and it had three restriction sites for EcoRI, how many fragments would you produce? What if you had a circular piece of DNA?
Please help! Is somewhat urgent :(
If we took a linear piece of DNA and cut it with the restriction enzyme EcoRI which had three restriction sites for EcoRI, then the resulting number of fragments that it would produce is five (5) fragments in a linear sequence and four (4) fragments in a circular piece.
What is a restriction enzyme?A restriction enzyme is a protein that has a defined catalytic activity that can be used to cut a given sequence of nucleic acids.
In this case, the EcoRI restriction enzyme can be used to cut in a specific nucleotide sequence that contains a given linear order of nucleotides in the cutting site.
Therefore, with this data, we can see that the restriction enzymes are able to cut the nucleic acids in specific sequences such as the EcoRI restriction enzyme that cut at particular nucleotide regions (this enzyme cuts at AATT positions).

Which of the following statements concerning cell membranes is/are correct?
Cells membranes are a phospholipid bilayer, with the hydrophobic "tails" of the phospholipids oriented to the interior of the bilayer, and the hydrophilic "heads" to the exterior of the bilayer.
They are fluid, which means that other molecules in them, such as proteins, are not fixed in position. One of the components of the membrane in animal cells is cholesterol, which helps to give rigidity and strength to the membrane
The cell membrane is impermeable to ions and polar molecules, while hydrophobic molecules can pass by passive diffusion.
This means that only statement 2 is true (option b).
Does diffusion take place in the nervous system? if it does, how so?
Answer:
In living things, diffusion allows substances to move in and out of cells. It's how red blood cells distribute oxygen through the body. When empty blood cells enter the lungs, which have an extremely high concentration of oxygen, the molecules pass into the blood cells, filling them up.

what happens when change in the dna is not repaired in a cell that will become an egg or sperm?
What happens when a change in the DNA of an egg or sperm is not repair will depend on the location of the mutation. This means that whether the changed DNA region is a gene, a regulating sequence or "junk" DNA, the cell can survive or not. In case it survives, the replaced nucleotide may not altere the protein it codifies, resulting in a silent mutation, or it can cause altereations in the functioning even though not being lethal.
The function of most proteins depends primarily on the?
The function of most proteins depends primarily on the Tertiary structure which formed by peptide bond, hydrogen bond, covalent bond, and disulphide bond.
Protein Structure- The three-dimensional configuration of an amino acid-chain molecule's atoms is known as protein structure. Segments of amino acids, the polymer's monomers, are used to create proteins, specifically polypeptides. A single amino monomer can also be referred to as a residue, which denotes a polymer's repeating unit.
Peptide Bond- Whenever the carboxyl group with one molecule combines with amino amino group of another molecule, the outcome is the production of an amide group and a water molecule, which is known as a peptide bond.

The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers. Many scientists advocate restoring wetlands (as well as creating them) as a strategy to reduce the severity and extent of the dead zone. The idea is that plants in healthy intact wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. List at least two potential benefits to this strategy, as opposed to a more traditional chemical intensive approach such as that used at most waste water treatment plants.
1. Restoring wetlands could be cheaper in the long run, once the ecosystem is restored it maintainace will not be as costly as that of water treatment plants.
2. This strategy also will be benefical for biodiversiy conservation and would bring ecosystems services to surrounding communities.

The gray matter is located in the brain. It is found in the outermost layer of the brain. It is surrounding the cerebrum and is called as cortex of the brain. The white matter is located in the further tissues of the brain or the subcortical. It is found underneath the gray matter. These are all located in the cerebral cortex.
The gray matter facilitates the control movement, memory, and emotions of an individual. The white matter is for learning and brain functions.
Answer:
Gray matter is home to neural cells, axon terminals, dendrites and nerve synapses. It is commonly found in the cerebellum, cerebrum, and brain stem. It gets its name due to its gray color.
White matter is located in the deeper tissues of the brain, and contains nerve fibres, and extensions of nerve cells. A substance called myelin gives white matter its white color.

the chloroplasts of land plants are thought to have been derived according to which evolutionary sequence?
the chloroplasts of land plants are thought to have been derived according to evolutionary sequence:
cyanobacteria → green algae → land plants
A population's genetic makeup evolves throughout time as a result of the process of evolution. Adaptations made by organisms to their altering surroundings are reflected in evolution, which can lead to changed genes, unique features, and the emergence of new species. Both increases in genetic diversity and shifts in allele frequencies throughout time affect evolutionary processes. Experimentally, the evolutionary process from a "Big Bang" genesis to the protocell and from the advent of the protocell and a diversity of species to Darwin's mental capacity (mind) and society is being reexamined (The Descent of Man). The focus on endogenous ordering is one of studies' most fundamentally revisionary effects.
This concept has had a fresh influence on the notion of Darwinian evolution and has been discovered to apply to the whole sequence. It is well demonstrated in the orderly copolymerization of amino acids. I'll go through a few issues with handling the teaching of contentious themes in this section.

What are hair cells ?The basic sensory receptor cells in the inner ear, known as hair cells, transduce, or change into electrical impulses that are sent to the brain, mechanical sensations generated by sound and head motions.
The sensory receptors of the auditory and vestibular systems in the ears of vertebrates are found in hair cells, which are distinguished by the stereocilia bundle at their apical surface. Mechanical impulses are converted into electrical activity by hair cells.Due to the hair-like cilia—stiff, nonmotile stereocilia and flexible, motile kinocilia—that extend from the apical ends of the sensory cells, they are known as hair cells.
