Answer:

The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%

Explanation:

A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.

In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

The organism that obtains energy without directly depending on another organism is a PLANT.

PLANTS are organisms which are capable of manufacturing their own food  through the process of photosynthesis.

Photosynthesis is defined as the process by which plants use low energy containing inorganic compounds (example carbondioxide and water) in the presence of sunlight, as energy, to produce high energy organic compounds such as sugar. These sugar are used as source of energy in the plant cells.

While animals are the organisms that directly depend on plants( another organism)

The electric potential at a point on the axis of the annulus a distance z from its center is given by:  \(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

To exploit the angular symmetry of the problem, we can consider a circular ring of radius r and thickness dr, with charge density λ. The potential dV at a point P on the axis of the ring, at a distance z from the center of the ring, due to a small element of charge dq on the ring is given by:

\(dV = kdq / sqrt(r^2 + z^2)\)

where k is the Coulomb constant.

We can express the charge density λ in terms of the total charge Q on the ring and the circumference C of the ring as:

λ = Q / C = Q / (2πr)

Substituting this expression into the equation for dV and integrating over the entire ring, we get:

\(V = ∫dV = kQ / (2π) ∫dr / sqrt(r^2 + z^2)\)

To evaluate the integral, we can make the substitution \(u = r^2 + z^2, du = 2rdr,\)  to obtain:

\(V = kQ / (4πz) ∫du / sqrt(u) = kQ / (4πz) * 2sqrt(u) = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

Therefore, the electric potential at a point on the axis of the annulus a distance z from its center is given by:

\(V = kQ / (2z) * sqrt(r^2 + z^2) / (2π)\)

Phagocytes are a type of immune cells that specialize in engulfing and digesting foreign particles, such as bacteria, viruses, and cellular debris. The two phagocytes are Neutrophils and Macrophages.

Neutrophils are a type of white blood cell and are the most abundant phagocytes in the bloodstream. They are quick to respond to infections and are often the first immune cells to arrive at the site of an infection. Neutrophils engulf and destroy pathogens by a process called phagocytosis.

Macrophages are a type of white blood cell that is present in various tissues and organs of the body. They are highly specialized phagocytes and play a crucial role in engulfing and eliminating foreign substances. Macrophages not only participate in immune responses but also contribute to tissue repair and maintenance.

The correct answer is Neutrophils and Macrophages.

Answer:

YES NO

Explanation:

To move charges, there needs to be a motive or a driving force that facilitates the flow of electric charges through a conductor. This motive can be provided by various factors and mechanisms.

One of the primary motives for the movement of charges is the presence of an electric field. An electric field exerts a force on charged particles, causing them to move in a particular direction. This force can be generated by applying a voltage difference across a conductor, creating an electric potential difference. The charges will naturally move from an area of higher potential to an area of lower potential, driven by the electric field.

In addition to electric fields, other motives for charge movement can include electromagnetic induction, where a changing magnetic field induces a current in a conductor, and chemical reactions, such as in batteries or fuel cells, where the conversion of chemical energy into electrical energy creates a motive for charge flow.

Ultimately, the motive for moving charges is provided by the presence of a force or potential difference that can overcome any resistances or obstacles in the conductor, allowing the charges to move and establish an electric current.

Homologous chromosomes are paired because they carry the same genes in the same order, although the alleles for each trait may differ.

During meiosis, the homologous chromosomes align during prophase I and exchange genetic material through a process called crossing over, which contributes to genetic diversity.In human beings, a pair of homologous chromosomes is present in every cell, one from each parent.

In females, the two X chromosomes are homologous pairs, while in males, the X and Y chromosomes are not homologous pairs since they carry different genes. During fertilization, the homologous chromosomes from the two parents pair up, and each gamete contains only one of each homologous chromosome.

Answer: The amount of oxygen in the atmosphere increased.

Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.

The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.

The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.

When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

Answer:

When a  macromolecule contains repeated similar sub units of a particular molecule:such a repeated units are called polymers.

Therefore, polyethylene is a micromolecule of repeated subunits  called ethylene formed during polymerization..Therefore, the small units joined together to form polyethylene are ethylene.These are alkene hydrocarbons,which are similar in structure with the carbon  atoms  linked by double bonds.When the Pi bonds of the double bonds breaks. hydrogen atoms forms free covalents bonds in all these sub units.

However, polypeptides is made of of 20 different amino acids, connected by peptides, disulfide and other bonds.Therefore the protein molecules will be different from the polyethylene and polymers. This is because each of the 20 amino acids has different R-groups, and It is this  R-groups that determine the functional characteristics displayed by each amino acid sub- units.Therefore, the characteristics of a protein molecule will be determine by the type of Amino acids it contains.

Thus the beads of polyethylene will be the same, but different in proteins
