Answer:
The stomach is J-shaped and it can expand to temporarily store food. Partial digestion of the food takes place here. The churning action of the stomach muscles physically breaks down the food. The stomach releases acids and enzymes for the chemical breakdown of food.

A glacier advanced 12 feet during a 16-day period in January. The same glacier advanced 18 feet during a 24-day period in February.
Are the ratios of feet to days proportional for these two periods of time?
Drag and drop to correctly complete the statement.
Answer:
3 feet : 4 days
Explanation:
Ratio of feet to days in January: Ratio of feet to days in February:
12 feet to 16 days 18 feet to 24 days
Now let us reduce both to the lowest terms and compare;
Divide by 4 Divide by 6
3 feet : 4 days 3 feet : 4 days
For both time periods, the ratio of feet to days are the same.

Scientists count the number of organisms in the tallgrass prairie. Which trophic level would you
expect to contain the smallest number of organisms?
A. Producers
B. Primary consumers
C. Secondary consumers
D. Tertiary consumers
Scientists count the number of organisms in the tallgrass prairie. The trophic level would you expect to contain the smallest number of organisms is Tertiary consumers. Thus, option D is correct.
Who are known as producers?The organisms that are capable of making their food like plants are called producers. The organisms that feed on the producers are known as primary consumers. The primary consumers include all kinds of insects, caterpillars, termites, etc.
Tussock larvae would be a primary consumer. The organisms that feed on the primary consumers are termed as Secondary consumers. In this example, the birds are eating the primary consumer i.e tussock larvae, hence birds would be the secondary consumers.
Therefore, Scientists count the number of organisms in the tallgrass prairie. The trophic level would you expect to contain the smallest number of organisms is Tertiary consumers. Thus, option D is correct.

As many as 30 thousand ____ _______ become entangled in lost or discarded fishing nets or cargo straps each year.
Answer:
As many as 30 thousand fur seals become entangled in lost or discarded fishing nets or cargo straps each year.
Explanation:
Human activities cause many damages to marine mammals in general. One of these activities is fishery. The nests are intercepting the migratory routes of animals or are floating free in the sea after being discarded. They are extremely strong, so whenever animals get stuck on them, they might carry them for months or years, affecting their diving, foraging, feeding, and reproductive behavior. These nets might hurt the animals´ skin, producing a wound that will probably get infected.
A few years ago, at least 50,000 northern fur seals died per year after getting stuck in fishing nets. The populations of these animals decreased sharply, affecting their reproductive and growth rates. In the present, due to the decrease in their population size, the number of dead animals is around 30,000 per year. This reduction in death is only because there are much fewer animals every year.
What makes up the highest percentage of soil composition?
A.) Mineral matter
B.) Water
C.) Air
D.) Organic matter
Answer:
D
Explanation:
^
The one that makes up the highest percentage of soil composition is mineral matter. The correct option is A.
What is soil composition?In soil science, a soil type is a taxonomic unit. A distinct soil type is formed by all soils that share a specific set of well-defined properties.
Soil type is a technical term for soil classification, which is the science of systematic categorization of soils. Every soil on the planet belongs to a specific soil type.
The composition of the soil is an important aspect of nutrient management. Soil water is what readily provides nutrients for plant uptake, whereas soil minerals and organic matter hold and store nutrients.
A typical soil contains about 45% mineral matter, 5% organic matter, 20-30% water, and 20-30% air. These percentages are, at best, broad strokes.
Thus, the correct option is A.

3. What temperature and density changes occur in a fluid or gas material that cause convection to occur?
Answer:
There is an increase in density and a corresponding increase in the temperature of the fluid
Explanation:
The temperature and density changes occur in a fluid or gas material that cause convection to occur include increase in density and a corresponding increase in the temperature of the fluid.
This is because convection involves the movement of fluids from a hotter area to a colder area and hot fluids usually have a lower density.
is Fat around organs
structure of cell membranes
protection
chemical messenger
Answer:
protection
Explanation:
The "fat" around the organs is called the "visceral adipose tissue." Its primary function is to "protect" the organs it encloses from injury. It also keeps the person warm especially when exposed to cold environments. Besides this, it also serves as a storage area for your calories in the body. Fat is not completely harmful as most people think.
This is the reason why it is not good to lose so much weight or become too skinny because losing some fat may be harmful to your organ's protection and heat regulation.

2. what close the valves in the heart and why should they do this?
3. what do we call a pulse?
4. describe blood capillaries
Your heart has four separate chambers that pump blood, two on the right side and two on the left.
2. When the ventricle relaxes, the aortic valve closes to prevent blood from flowing back into the ventricle. When the aortic valve is not working properly, it can interfere with blood flow and cause the heart to strain to send blood to the rest of the body.
3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.
4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
