The number of chromosomes present in the secondary oocyte are 23.

Secondary oocyte is the immature ovum that is formed from the primary oocyte after cell division. Primary oocyte is the diploid cell which divides by meiosis to give rise to secondary oocyte. This is the reason why secondary oocyte has half the number of chromosomes than actual.

Chromosomes are the compact structures that consist of the DNA strand and histone proteins. The structure of chromosomes is composed of two chromatids called sister chromatids that are joined together at the centromeric region. The transfer of genetic material from parent to offspring takes place in chromosomal form.

Answer:

cytoplasm

Explanation:

the material or protoplasm within a living cell, excluding the nucleus.

Answer:

1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.

2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

Answer:

Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.

Explanation:

Answer: In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

 options a, b, and c are not accurate conclusions based on the given information.

The correct answer is d) They will be haploid (2n). Gametes are haploid cells, meaning they contain half the number of chromosomes as somatic cells. Since the insect's gamete contains 4 chromosomes, the somatic cells would have a diploid number of 8 chromosomes (2n = 8). The amount of DNA in the gamete is not necessarily indicative of the amount of DNA in the somatic cells, as somatic cells can undergo DNA replication and have varying amounts of DNA depending on the stage of the cell cycle.

The enzymes break down the bolus of food, converting it into semiliquid mass of partly digested food and digestive secretions known as chyme.

The digestion process involves four phases. Ingestion, or gathering food into the digestive secretions, is the initial phase. Although it may appear like a straightforward process, ingestion entails smelling the meal, contemplating the food, and the uncontrollable production of saliva in the mouth to get ready for food entry. The first stages of the mechanical and chemical breakdown of food start in the mouth, where the second stage of digestion takes place. Enzymes are used in the chemical breakdown of food to separate its constituent parts. Amylase, an enzyme that starts breaking down complex carbohydrates, is secreted in the mouth. Mastication, or chewing, in the mouth is the first stage of mechanical breakdown.

Human vision studies have shown that some people can detect 545-nm light with as few as 100 photons entering the eye per second. The power delivered by such a beam of light is approximately 36.33 femtowatts.  

To calculate the power delivered by a beam of light, we need to consider the energy carried by each photon and the number of photons entering the eye per second.

The energy of a photon can be calculated using the equation E = hc/λ, where E is the energy, h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3 x 10^8 m/s), and λ is the wavelength of light.

In this case, the wavelength is given as 545 nm (nanometers), which can be converted to meters by dividing by 10^9. Therefore, λ = 545 x 10^-9 m. Substituting these values into the equation, we can find the energy of each photon:

E = (6.626 x 10^-34 J s)(3 x 10^8 m/s)/(545 x 10^-9 m) ≈ 3.633 x 10^-19 J

Now, we need to determine the number of photons entering the eye per second. The question states that some people can detect 545-nm light with as few as 100 photons entering the eye per second.

To calculate the power, we multiply the energy of each photon by the number of photons entering the eye per second:

Power = (3.633 x 10^-19 J/photon)(100 photons/s) = 3.633 x 10^-17 J/s = 36.33 femtowatts (fw)

Therefore, the power delivered by such a beam of light is approximately 36.33 femtowatts. It's worth noting that this calculation assumes perfect efficiency in the conversion of light energy into neural signals in the eye.
