Prescribed burns can help maintain healthy ecosystems.
Fire is a natural, common process in various ecosystems and is important to preserve a healthy forest and the quality of plant and animal growth. Many plants and animals have not only accommodated to fire but truly depend on it such as the lodge pole pine which requires fire to support in the scattering of its seeds. Naturally occurring fires also support to administer pests and disease under control by eliminating the pathogens contaminating a stand.
Prescribedburns can help maintain healthy ecosystems. The correct option is c.
Prescribedburns, also known as controlled burns or planned fires, are intentionally set fires conducted under specific conditions and managed by trained professionals.
Thus, the correct option is c.

The major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.
Gram-positive bacteria do not contain an outer plasma membrane, whereas Gram-negative bacteria have a lipid-rich outer plasma membrane.
This outer plasma membrane contains lipopolysaccharide (LPS) in addition to phospholipids and proteins.
Moreover, Gram-positive bacteria are also surrounded by thick layers of peptidoglycan.
In conclusion, the major difference between Gram-positive and Gram-negative bacteria is the presence or absence of an OUTER PLASMA MEMBRANE.

Answer:
Microbiologists use the gram stain technique to identify the gram-positive and gram-negative bacteria on the basis of the composition of their cell wall.
The major difference between the cell wall of gram-positive bacteria and gram-negative bacteria is that in gram-positive bacteria peptidoglycan is the major component which makes gram-positive cell wall whereas in gram-negative bacteria their cell wall has a thick outer layer of Lippo polysaccharide and a thin inner layer of peptidoglycan.
So in gram stain gram-positive cell wall retains the crystal violet because of the thick peptidoglycan layer and appears violet and gram-negative appears pink as it lacks the outer thick peptidoglycan layer.
b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.
Answer;
The experiment would lack a control group
Explanation;
-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.
-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.
-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
they need the Sun's energy in order to produce food
water is essential to a plant's growth
strong stems are more wind resistant
co-adaptation
mass extinction
instantaneous speciation
A particular plant species is pollinated by a certain insect species. The insect species depends on the plant species for food. This relationship is based on co-adaptation.
Here co-adaptation refers to the mutual adaptation between the given species(plants and insects) that depend upon each other.
