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
Answers
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.
Complete a Punnett square for the cross-pollination of a female (TT) and a male (Tt). Write in the correct answers to complete the square.
Answers
Answer:
The correct answer is -
50% chances of Tt
50% chances of TT
Explanation:
In the given question it is given that there is a cross-pollination between a female (TT) and a male (Tt), which means female has two dominant copies of a trait in her genotype while the male is a heterozygous, the gametes of these genotypes will be:
gametes: T, t and T, T
then cross will be:
T T
T TT TT
t Tt Tt
Thus, the given result shows 1/2 TT and the rest 1/2 Tt by this Punnett square.
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
Answers
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.

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
Answers
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.
What would most likely happen to a native predator species if a nonnative predator species were introduced to an area?
A. The native species would force the nonnative species out of the community
B. The native species population would decrease because the nonnative species would be competing for food sources.
C. The native species population would increase because the nonnative species would introduce new food sources.
D. The native species would outcompete the nonnative species.
Answers
Answer:
B. The native species population would decrease because the nonnative species would be competing for food sources.
Explanation:
This question is describing the effect of invasive species. Invasive species are foreign species i.e. not native to a habitat or area, introduced into the area with the ability to outcompete and negatively affect the native species of that area.
Invasive species compete with the native species for food, space, mate etc., and tend to outgrow them. Hence, if a nonnative predator (invasive) species were introduced to an area, the native predator species in that area would decrease because the nonnative species would be competing for food sources.
At each ______ foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the ______.
Answers
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.
