Answer:
Explanation:
Secondary succession usually occurs faster than primary succession because the substrate is already present. In primary succession, there is no soil and it needs to form. This process takes time, as pioneer species must colonize the area, they must die, and as this happens over and over again, soil forms.

Describe how scientific investigations lead to new scientific questions.
Answer:
Scientific investigations produce evidence that helps answer questions and solve problems. If the evidence cannot provide answers or solutions, it may still be useful. It may lead to new questions or problems for investigation. As more knowledge is discovered, science advances.

O by using the latest technologies
O through the testing of hypotheses
O by making value judgments
O through deductive reasoning
Science gains knowledge and understanding through the testing of hypotheses.
A hypothesis is a given explanation of a particular phenomenon from the real world, which is tested (i.e., either verified or rejected) by using the scientific method.The scientific method is a methodology based on experimental and observational procedures that allow obtaining and interpreting empirical evidence.Subsequently, the evidence obtained from experimentation and/or observation is assessed in order to accept or reject the working hypothesis.Learn more in:

How do plant and animal breeders
use the process of artificial
selection to increase productivity
in their crops and herds?
A. The breeders choose organisms with the most
desirable traits and breed them.
B. The environment selects the traits that are
passed on, and the breeders have no control over
it.
C. Artificial selection is a theory and does not
work, so breeders do not use it.
A animals and plants have sources
I think
Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits.Thus, option A is correct.
What plant and animal breeders process artificial selection?Selective breeding is the practice of pairing parents who share particular features in order to produce offspring who have a greater number of desirable traits. Humans have carefully selected a wide range of plants and animals for thousands of years, including agricultural species with higher yields.
Instead of allowing the species evolve spontaneously without human involvement, as in natural selection, people chose animals or agricultural products based on desirable qualities, a practice known as "selective breeding,” or artificial selection.
Therefore, The breeders choose organisms with the most desirable traits and breed them.

layers of
make up the cell membrane.
The cell membrane is composed of two main layers called phospholipid bilayer. Each layer is made up of phospholipids, which are a type of lipid molecule.
These phospholipids have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. The hydrophilic heads are attracted to water, while the hydrophobic tails repel water.
The phospholipid bilayer consists of two layers of phospholipids arranged in such a way that the hydrophilic heads face the outside and inside of the cell, while the hydrophobic tails are sandwiched in between. This arrangement creates a barrier that separates the inside of the cell from the outside environment.
In addition to phospholipids, the cell membrane also contains other molecules such as proteins, cholesterol, and carbohydrates. Proteins are embedded within the phospholipid bilayer and serve various functions, such as transporting molecules across the membrane or acting as receptors for signaling molecules.
Cholesterol molecules are interspersed between the phospholipids and help maintain the fluidity and stability of the cell membrane. Carbohydrates are attached to proteins or lipids on the outer surface of the cell membrane and play a role in cell recognition and communication.
Overall, the cell membrane is made up of phospholipids, proteins, cholesterol, and carbohydrates, all working together to regulate the passage of molecules in and out of the cell and to maintain the integrity and functionality of the cell.

What would an organism need to do to release energy
from a carbohydrate, a lipid, or a protein? What two
elements are involved?
Organism needs enzymes in order to release energy from carbohydrate, a lipid, or a protein.
Amylase is the enzyme which is responsible for the breakdown of carbohydrates secreted by salivary glands. Pepsin, trypsin and chymotrypsin are the enzymes responsible for the digestion of proteins while on the other hand, lipase is the enzyme that is responsible for the digestion of fats in the body so we can conclude that enzymes are required by the organism for the release of energy.
