Sort the steps of digestion in order from beginning to end.
- The stomach kills some bacteria and breaks food down into chyme.
- Nutrients from dissolved food are absorbed from the small intestine into the bloodstream.
- Water and nutrients are absorbed by the large intestine; chyme becomes waste matter.
- Saliva mixes with food and changes starches into sugars.
Saliva mixes with food and changes starches into sugars is the beginning step of the digestion.
What are the functions of saliva?Saliva is the medium that bathes the taste receptors in the oral cavity and in which aroma and taste compounds are released when food is eaten.
It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells.
Saliva moistens the mouth for comfort, lubricates as you chew and swallow, and neutralizes harmful acids. It also kills germs and prevents bad breath, defends against tooth decay and gum disease, protects enamel, and speeds up wound healing.

what are the mechanisms that halophiles typically employ to grow in habitats with high concentrations of salt
Answer:
Synthesis Of Osmoprotectants
Explanation:
One Mechanism Halophiles use to survive in high concentrations of salt is the Synthesis Of Osmoprotectants, which are also known as compatible solutes. These work by balancing the internal osmotic pressure with the external osmotic pressure, making the two solutions isotonic, or close to it.

An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes contact with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. The pH in the vesicle is then lowered and the contents are degraded.
What type of transport is involved in this process?
A.
endocytosis
B.
diffusion
C.
passive transport
D.
exocytosis
Answer:
A. endocytosis
Explanation:
Endocytosis is the type of transport that is involved in this process because it engulf the food material. Amoeba engulfs food particles with the help of its pseudopodia which are the projections of cell membranes. A food vacuole is formed around the food particle. This process of engulfing a matter by the projections of the cell membrane to form a vacuole is called endocytosis.
Lisa is giving a speech about Pandas. Her speech includes 3 points: 1) where pandas live; 2) what pandas eat; and three) how pandas reproduce. What type of organization is Lisa using?
Answer:
Topical order.
Explanation:
Text structure can be defined as words used to describe how a writer or an author organizes his or her words in a literary work.
A topical order refers to a way of structuring a text or organizing a speech based on the main topic and dividing it into several subtopics in logical categories (steps).
In this scenario, Lisa is giving a speech about Pandas. Her speech includes 3 points:
1) Where pandas live.
2) What pandas eat.
3) How pandas reproduce.
Thus, the type of organization Lisa is using is topical.
In conclusion, a speech or text organized in a topical order has its main points organized as subtopics which are well related with the main topic.
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.
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.
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
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.

When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. concentration gradient pressure gradient electrical gradient temperature gradient
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

List the negative impacts of human activities on vegetation?
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

Explanation:
At each ______ foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the ______.
Answer:
At each intervertebral foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the spinal nerves.
Explanation:
The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs. In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.
