C. Response to a stimulus only
D. Reproduction and growth and development

Answer:

Females have two X chromosomes in their cells, while males have both X and a Y chromosomes in their cells. Egg cells all contain an X chromosome, while sperm cells contain an X or Y chromosome. This arrangement means that it is the male that determines the sex of the offspring when fertilization occurs.

Answer:

There are 8 food chains

Explanation:

Answer:

Ventral

Explanation:

This is because when you want to dissect a pig, it's back is place on a dissecting tray and it's belly side is up which is the ventral side. With the ventral side, dissection will be easy and the major organs and systems can be observed easily as they will be rightly viewed because they are obvious and rightly placed at belly side up.

Answer:

Meanwhile, the ovary itself releases a hormone called estrogen which causes the uterine lining to increase in thickness. The uterine lining becomes thicker so that the fertilized egg can attach to it. It is correct.

Explanation:

The hypothalamus, which is in the brain, releases a hormone called Gonadotrophin Release Hormone (GnRH). GnRH travels to the hypophysis, which is a gland located in the lower part of the skull. The GnRH makes the hypophysis release a hormone called Follicle Stimulant Hormone (FSH). This hormone travels to the ovaries, making it release estrogen. This hormone is in high concentrations during the 4th or 6th day of the cycle up to the 14th day, which is when ovulation happens. Estrogens make the endometrium, which is the outer layer of the uterus, grow making it thicker to prepare itself to attach the fertilized egg and provide to it the necessary nutrients to grow.

If the fertilization does not happen, the thickened endometrium will be expelled from the uterus some days later during menstruation.

In females, the uterine lining is at the site of fertilized egg attachment. The attachment of the fertilized egg makes the lining thicker.

The estrogen hormone is produced by the ovaries of females. The hormonal cycle with rising, estrogen, and progression causes the menstrual cycle.

The non-fertilized egg triggers the release of estrogen, and the uterine line sheds off.

However, the fertilization of the egg results in a decreased signal of estrogen in the female body, and the uterine lining becomes thick without shedding.

Thus, the statement about the thickening of the uterine lining with the fertilization of the egg is correct.

Answer:

The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Answer: The main difference between organ and organelle is that organ is a large part of an organism, composed of tissues which perform similar functions whereas organelle is a specialized structure found inside cells, which carries out a specific life process. Organelles form cells.

Answer: Mitochondria

Explanation:

Answer:

Yes.

Explanation:

Yes, the positive charges on both calcium ions and sodium ions will responsible for the movement of these ions into or out of the cell because the membrane has negative charge which attract these positively charged calcium ions and potassium ions. These difference concentrations of sodium and potassium in the cell are due to the activity of cell membrane active transport system which moves sodium out of the cell and potassium into it.

Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.

Diffusion may be defined as a process resulting from the random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

The membrane of a cell possesses a negative charge, so it attracts these positive charge ions and makes a concentration difference that leads to the process of active transport through which sodium moves out of the cell and potassium into it.

Therefore, Yes, the positive charges of calcium ions and sodium ions make these ions more likely to move into or out of the cell.

Vision: Occipital

Memory: Temporal

Explanation:

The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch.

Answer: phenotype. An organism's physical appearance, or visible traits. genotype. An organism's genetic makeup, or allele combinations.

The physical appearance of an organism is called its phenotype.

An organism's physical appearance also known as its phenotype refers to the observable characteristics that result from the interaction between its genetic makeup (genotype) and environmental influences. These traits can include features such as size, shape, color, and behavior.

The phenotype is the manifestation of an organism's genes and how they are expressed and it vary both within and between species. Studying phenotypes is important for understanding genetic inheritance, evolution and the overall diversity of life on Earth.
