In the African savanna, more wildebeests are born than the environment can support. Which is most likely to happen over a period of years as a result?
The chances for survival of the population are reduced.
New food sources are discovered and become the regular diet.
Individuals that are well suited to the environment reproduce, and those that are not well suited die before they reproduce.
The environment adapts by providing more resources to the growing population, increasing the chances of survival for individuals within the habitat.
Answer: I think the correct answer from the choices listed above is option C. Over a period of years, most likely, individuals that are well suited to the environment reproduce, and those that have lesser adaptations die before they reproduce. Hope this answers the question.

Which is an advantage of genetic engineering?
A lack of labeling of food products that have been genetically engineered
B diminished opportunities for organic agriculture
C lack of long-term studies on food safety and environmental impact
D diminished effects of diseases on crops
Answer:
The answer is D.) Diminished effects of diseases on crops.
Explanation: I just took the quiz on edge 2021 :)
An advantage of genetic engineering is the diminished effects of diseases on crops. The correct option is D.
What is genetic engineering?Genetic engineering, often known as genetic modification or genetic manipulation, is the use of biotechnology to directly manipulate an organism's DNA.
The manipulation or modification of an organism's DNA or cells is known as genetic engineering. Cloning is an excellent illustration of genetic engineering in action.
The main worries concerning the negative consequences of GM foods on health include the transmission of antibiotic resistance, toxicity, and allergenic. From the standpoint of allergies, there are two difficulties.
Therefore, the correct option is D, diminished effects of diseases on crops.

explain how the equilibrium price is determined
Answer:
The equilibrium price is the price at which the quantity demanded equals the quantity supplied. It is determined by the intersection of the demand and supply curves. .
A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease.

Type the correct answer in the box. Spell all words correctly. Which microscope allows two samples to be viewed simultaneously? Forensic scientists use the microscope to view two samples simultaneously at extreme magnification.
Answer:
Comparison microscope
Explanation:
The correct answer would be the comparison microscope.
The comparison microscope consists of two compound microscopes with a center eyepiece. The eyepiece captures and displays the images from the two microscopes and the observer can compare and contrast for investigative purposes.
The capacity to produce two images for comparison purposes makes the microscope useful in forensic investigations.

Jimmy explained on his biology test that organisms grow because their cells grow. Explain why his answer is either right or wrong and if he is
wrong explain how organisms actually grow.
Answer:
See the answer below
Explanation:
Jimmy was right to say organisms grow because their cells grow.
The growth of organisms can happen in terms of an increase in the number of cells they have (through mitotic cell division) or an increase in the volume of the cells with or without an increase in the number of cells.
A good example is found in plants, most of which undergo an increase in size without any increase in the number of cells in their bodies. The uptake and storage of water in the vacuole produces a pressure that pushes on the cell walls, causing an increase in length, girths, and other growth features of the cells of plants.
Microfilaments are a component of a cell's cytoskeleton and are made of the protein actin. They are important for giving a cell its shape and also aid in _______.
A.) Protein synthesis
B.) Cellular movement
C.) DNA replication
D.) Energy conversion
Microfilaments are a component of the cell's cytoskeleton and these are made up of the actin protein. They are involved in the cellular movement. Thus, the correct option is B.
What are Microfilaments?Microfilaments are also called as actin filaments, as they consist of two intertwined strands of a globular protein, which is known as actin protein. In association with myosin, microfilaments help to generate forces that are used in cellular contraction and cellular movements. During cell division, these filaments results into dividing cell to pinch off into two daughter cells and are involved in amoeboid movements of certain types of cells.
Microfilaments assist with cellular movement due to the presence of actin filaments. Actin filament works with another protein called myosin to produce muscular movements, cell division, and cytoplasmic streaming during cell division. Microfilaments keep the organelles in place within the cell.
Therefore, the correct option is B.

When the concentration of molecules are the SAME on both sides of the cell
membrane, the solution is *
A. Hypertonic
B. In equilibrium
C. Hypotonic
D. Kinetic
Answer:
isotonic: in equilibrium.
Explanation:
tonicity is the relative concentration of solutes dissolved in solution which determine the direction and extent of diffusion. if let's say sodium is the same both inside the cell membrane and outside the cell membrane then it is isotonic in equilibrium.

When a human cell divides in mitosis, the two daughter cells will each have: _____
Answer: In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.
