a. The ovum contains a large quantity of cytoplasm, which contains nutrients for the first days of development after fertilization. The cytoplasm of the ovum contains over 140 000 mitochondria to produce ATP required for growth.



b. The uterus contains over 140 000 mitochondria to produce ATP and supplies this to the egg for growth.

d. The ovum contains a large quantity of fimbria, which contains nutrients for the first days of development after fertilization.

Answers

Answer:

Until attachment to the uterus, the developing organism is on its own. That means it needs to supply its own energy, so the cytoplasm of the human egg cell contains many energy-generating factories called mitochondria. Those mitochondria come only from the mother.

The nuclei (the structure inside a cell that contains DNA) of the cheek cells have been stained using a special dye so that they appear purple. What shape are they

Answers

Answer: Oval.

Explanation:

The nucleus of a cell is a membranous structure normally found in the center of eukaryotic cells and is where most of the cellular genetic material is found, organized in DNA molecules (deoxyribonucleic acid) associated with proteins such as histones, which make up the chromosomes.

The function of the nucleus is to maintain the integrity of the genes in the DNA and to regulate gene expression to control cellular activities. It then controls when DNA is transcribed into RNA (ribonucleic acid) and when it is exported to the cytoplasm to be translated into proteins.

The nucleus is composed of a nuclear envelope consisting of a double membrane that surrounds it, as well as pores that allow the passage of RNA for the regulation of gene expression.

The cells of the inner cheek are classified as non-keratinized stratified squamous epithelium. An epithelium is a tissue made up of joined cells that line the outer surface of the body and inner organs. Squamous cells are flat, scale-like, whereas stratified cells are arranged in multiple layers. Non-keratinized means that the cells constitute soft tissue found in the moist parts of our body, such as the mouth, stomach, among others. In a normal healthy cell, the nucleus is uniformly stained, oval in shape and smaller in relation to the cytoplasm.

Which of the following statements describes the conditions of a pneumothorax? View Available Hint(s) Which of the following statements describes the conditions of a pneumothorax? The intrapulmonary pressure equalizes to atmospheric pressure. Both lungs partially or completely collapse. The intrapleural pressure decreases. The presence of air in the pleural cavity.

Answers

Answer:

The presence of air in the pleural cavity

Explanation:

A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

Answers

Answer:

exhibit a net movement to the side with lower free water concentration

Explanation:

The correct answer would be that the water will exhibit a net movement to the side with lower free water concentration.

Osmosis is generally defined as the movement of water molecules through semi-permeable membranes from the region of higher water potential or lower solute concentration to the region of lower water potential or higher solute concentration.

From the definition, it becomes obvious that there would be a net movement of water between the two solutions to the side with higher solute concentration or lower free water concentration.

What is an endoscope?

An endoscope is a medical instrument that consists of a long, thin, flexible tube equipped with a light source and a camera at the tip. It is used by doctors to visualize and examine internal organs or structures within the body. The endoscope can be inserted through natural body openings like the mouth, anus, or small incisions to access various areas of the body.

It allows for direct visualization of the internal organs, capturing real-time images or videos that can be viewed on a monitor. Endoscopes are commonly used for diagnostic purposes, such as examining the gastrointestinal tract, respiratory system, urinary tract, or joints. They can also be used for therapeutic procedures, such as removing polyps, taking biopsies, or performing minimally invasive surgeries.

Endoscopes have revolutionized medical diagnostics and interventions by providing a less invasive alternative to traditional surgical methods.

Make me brainliest pls

The term that is used to describe the number of deer in a square kilometer of forest is population density.

What is population density?

Population density is a measure of how crowded or dispersed a population is in a particular area. It is calculated as the number of individuals of a particular species per unit of area, such as square kilometer or square mile. This measure helps to understand the concentration of individuals of a species in a given area. A high population density means there are more individuals of a species per unit area, whereas a low population density indicates fewer individuals in a given area.

Population density plays a crucial role in understanding and predicting the effects of population growth on the environment. High population density can lead to increased competition for resources such as food, water, and shelter, which can cause stress on the ecosystem. It can also lead to an increased risk of diseases and higher rates of pollution. In contrast, low population densities can lead to the extinction of species due to lack of genetic diversity and inbreeding. Understanding population density is important for conservation biology, urban planning, and resource management, among others.

d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.

Answers

The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.

Explanation

Ovulation is a process in which the ovum is released from the ruptured follicle, there it is captured by the fimbriae and taken to the fallopian tubes (where it will be fertilized by sperm) and then it will reach the uterus (the place where the fetus will grow) through the cilia. Additionally, this process is in which the woman is fertile to conceive and occurs around the fourteenth day of the menstrual cycle (which lasts twenty-eight days).
