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.

Cells are made of organelles, specialized structures that each perform specific functions that help the cell maintain homeostasis. This is much like the body systems work together to help the body maintain homeostasis. Consider the function of the nervous system. Which organelle is most similar in function?
Answer:
Organelles serve specific functions to keep a cell alive.
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Answer:
Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance
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.

Many populations exhibit the following growth curve.
Which statement(s) below accurately are describing the growth as shown on the graph. NOTE: There is MORE THAN ONE correct answer. Choose ALL that apply.
Select 3 correct answer(s)
Question 5 options:
Phase B of the graph is showing a population that has reached its carrying capacity.
When both phases of the graph are looked at together, it shows logistical growth of a population after growing exponentially and reaching its carrying capacity .
Phase B of the graph is showing exponential growth only.
The entire graph shows two organisms competing for space.
Phase A of the graph is showing exponential growth only.
Many populations exhibit the following growth curve.. Here option 1, 2, 3 are correct which describe the growth. Phase B of the graph is showing a population that has reached its carrying capacity.
What is carrying capacity ?
The carrying capacity of the individual is the maximum number of population size of the species in a sustainable environment which is indefinitely reach up to the limit of no further growth.
Carrying refers to support and Capacity means it is the ability of an organism to reproduce the maximum output, when population reaches the limit of carrying capacity then the mortality will be greater than natality.
The importance of Carrying capacity is mainly focused on the concept of sustainability, imbalance in the environmental and Global warming which are the causative agent, eradication of poverty and practices are also increase the importance of carrying capacity.

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.
