Answer:
f a flower contains all four main parts ( sepals , petals, stamens, and carpels), it is called a complete flower. Sepal: This typically green, leaf-like structure protects the budding flower. Collectively, sepals are known as the calyx. Petal: This plant structure is a modified leaf that surrounds the reproductive parts of a flower.

How does soil composition affect the number and types of organisms an environment can support?
(Biome majors)
Answers
Answer:
The number of organisms an ecosystem can support depends on the resources available and abiotic factors, such as quantity of light and water, range of temperatures, and soil composition. Given adequate biotic and abiotic resources and no disease or predators, populations (including humans) increase at rapid rates.

pancreatic amylase is a digestive enzyme that digests starch in the small intestine. pancreatic amylase's optimum pH is slightly basic, which the presence of NaHCO3 provides. indicate which test tubes (1-3) would show digestion of starch following incubation. Explain why the others would not.
Tube 1 = water, starch
Tube 2 = water, starch, pancreatic amylase, HCI
Tube 3 = water, starch, pancreatic amylase, NaHCO3
Answers
Answer:
Tube 3
Explanation:
Pancreatic amylase's optimum pH is basic, NaHCO3 is a base so it will provide the optimum pH for the enzyme to catalyse the breakdown of starch.
In tube 1 there will not be the breakdown of starch as there simply isn't any enzyme to break it down.
In Tube 2, the enzyme pancreatic amylase will most probably become denatured (loss of shape), as HCl is acidic which causes it to lose shape causing a change in the active site and will never be able to catalyse the breakdown of starch.

Answer:
Explanation:
The exponential growth of the human population could lead to food shortages, global warming, and other issues of resource scarcity.
Answer:
Explanation:
Unsustainable population growth and lack of access to reproductive health care also puts pressure on human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for the most vulnerable communities to rise out of intergenerational poverty.

B. The model illustrates diffusion because solute particles are moving from an area of higher
concentration to an area of lower concentration
C. The model illustrates facilitated diffusion because protein channels allow solute particles
to cross the cell membrane.
D. The model illustrates osmosis because water molecules are moving from an area of higher
concentration to an area of lower concentration,
Answers
Answer:
A. The model illustrates active transport because energy is required for solute particles to cross the cell membrane.
Explanation:
Active transport is the transport of molecules from a region of lower concentration to a region of higher concentration. In other words, movement occurs against a concentration gradient.
Due to this, it requires energy in form of ATP for this movement to occur. Hence, based on this question, the model illustrates active transport because energy is required for solute particles to cross the cell membrane.

Independent variable: These are the variables that are manipulated or change to see the effect on the dependent variable, these are manipulated by the researcher. In this investigation, the independent variable is the temperature of the water as it affects the amount of sugar that dissolves.Dependent variables: these are the variable that also changes due to change and according to the change in the independent variables. In this investigation, the amount of sugar that dissolves changes according to the change in the temperature of the water, thus, its dependent variable.Constant or control: these are the parts that do not change during the experiment so there is no other influence occur in the Dependent variable.Thus, the correct answer is -

Compare the practices of shelterwood cutting, clearcutting, and seed-tree cutting.
ANSWER:
Clearcutting removes all the trees within a certain area at one time. Shelterwood cutting also removes all the trees in an area, but does it in stages over several years. Seed-tree cutting removes all the trees except for a select number of mature trees that can then reseed the area. Seed-tree cutting and shelterwood cutting allow for the harvested areas to recover over time without direct intervention
