Answer:

D: fatty acids is what a lipid is made up from.

Explanation:

An example of a lipid is cholesterol.  It is made up of a hydrocarbon tail and a carboxyl group. The correct option is A.

Lipids are biomolecular substances that are made up of hydrocarbons and have a non-polar end and are non-soluble in water. They form the structure and function of living cells.

Cholesterol is a lipid, found in the blood, our body needs cholesterol to make and repairing of cells.

Thus, the correct option is (A) cholesterol regarding an example of a lipid.

Answer:

The ecological footprint (EF) estimates the biologically productive land and sea area needed to provide the renewable resources that a population consumes and to absorb the wastes it generates—using prevailing technology and resource-management practices—rather than trying to determine how many people a given land area

Ecosystem services are the benefits that people obtain from ecosystems. Ecosystem services are indispensable to the wellbeing of all people, everywhere in the world. They include provisioning, regulating, and cultural services that directly affect people, and supporting services needed to maintain the other services.

Since a steady spray of water soaked into the soil, making it heavier. This student's experiment models: C. The role of rainfall in mass wasting.

A rock can be defined as a solid naturally occurring landform and it is typically made up of various minerals.

In this experiment, a stack of rocks was placed on a ramp and clumps of soil rooted with live grass were added. By using a garden hose, the student then applied a steady spray of water which soaked into the soil and made it heavier in weight.

Hence, this experiment models the role rainfall (steady spray of water) plays in mass wasting.

Mass wasting is also referred to as mass movement or slope movement and it can be defined as a geomorphic process through which rock, debris, soil, and regolith are largely moved downward, especially due to the force of gravity.

Basically, mass wasting describes the downslope (downhill) movement of rock and soil due to a steep slope and force of gravity.

In conclusion, the steady spray of water acts as a force which moves some of the soil constituents downward, making it heavier.

Answer: Felipe is wrong.

Explanation:

In diagram A, we can see that the light comes from the left, it first impacts on the Earth, and then we have the Moon.

Now, you can model this situation with a flashlight (the Sun) a basketball (the Earth) and a tennis ball (the Moon)

When you point with the flashlight at the basketball, the basketball will look bright, but it will cast a shadow behind it. This shadow will cover the tennis ball, and almost no light will reach the tennis ball, so it will not look bright.

This phenomenon is called a lunar eclipse, and this happens when the Earth is in between the Sun and the Moon. When this happens, we see the moon a bit darker and more reddish.

Felipe is incorrect, as it will not be possible to see the moon if it is in the position shown in the diagram.

We can come to this answer because:

Therefore, it will not be possible to see the moon, as Felipe said.

Answer:

Mostly HCl, Pepsin, Lipase, Water, and other Electrolytes

Explanation:

The gastric mucosa secretes 1.2 to 1.5 litres of gastric juice per day. Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine. Gastric juice is a variable mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulfate, and bicarbonate), and organic substances (mucus, pepsins, and protein). This juice is highly acidic because of its hydrochloric acid content, and it is rich in enzymes. As noted above, the stomach walls are protected from digestive juices by the membrane on the surface of the epithelial cells bordering the lumen of the stomach; this membrane is rich in lipoproteins, which are resistant to attack by acid. The gastric juice of some mammals (e.g., calves) contains the enzyme rennin, which clumps milk proteins and thus takes them out of solution and makes them more susceptible to the action of a proteolytic enzyme.

Autosomal recessive disorders are typically not seen in every generation of an affected family. X-linked dominant disorders are caused by mutations in genes on the X chromosome, one of the two sex chromosomes in each cell.

By the transfer of energy into a container of magnetic marbles the speed changes because of kinetic energy produced by the shaking of container gently. This will lead to phase changes.

All the phase changes in a system are accompanied by the change in the energy of a system. These include transfer of kinetic energy to a system. Changes from a more-ordered state to a less-ordered state are endothermic reactions. Changes from a less-ordered state to a more-ordered state are always exothermic reactions.

A phase change in a system takes place when a matter changes from one state to another state. These changes occur when sufficient amount of energy is supplied to the system or lost from the system. Phase changes also occur when the pressure on the system is changed.

1.Nitrification happens when soil organisms change over ammonium into nitrate. Much of the cover between the carbon cycle and the nitrogen cycle happens within the soil, in forms conducted by soil organisms. Organisms break down supplements, construct modern compounds for their possess development, and inevitably pass on.

The second question im not sure sorry- the positive and negative one ;(

3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.

4. Carbon makes its way through living things as carbon-based compounds, like vitality particles, fats and proteins, in the long run cycling its way back into the environment. Nitrogen is basically found within the air as well and enters the environments as supplements for plants. Water, nitrogen and carbon cycles. Carbon moves from the air and back by means of creatures and plants. Nitrogen moves from the environment and back by means of living beings.
