Eunice is a scientist studying a grassland area in the midwestern United States. It contains many species of flora and fauna that coexist and remain relatively balanced. There have also been no recent disturbances in the area. Which topic is Eunice’s project most likely about? secondary succession pioneer species primary succession climax communities.
Grasslands are ecosystems covered by grasses. The ecosystem can be a newly formed or previously established type. The project is most likely about the climax community.
What is climax community?The final or the last step of the ecological succession is called climax community, it remains unchanged till the conditions are stable and unaltered.
They are the communities of the flora and fauna that have attained equilibrium and does not undergo any extra changes. The organisms of the climax community adapt and interact with each other in a balanced way.
Therefore, option D. climax community is the most likely topic of the project.

Think about long-neck and short-
neck giraffes. What would happen
over time if all the shrubs and lower
leaves on the trees disappeared?
The short-neck giraffes would die out because the long-neck giraffes are better fit for that environment.
What is long neck of giraffe?A giraffe can reach leaves, fruit, and flowers that are high up in Vachellia or Senegalia (previously Acacia) and other desirable tree species because to its long neck.
Thus, with the exception of elephant, giraffe are suited to take advantage of a region of vegetation that is out of reach for all other terrestrial browsers. The advantage in height is further increased by their 45 cm long tongue and a modified atlas-axis joint that allows the head to stretch vertically.
Giraffe can reach higher than cows, whereas large bulls may browse the tops of small trees. Giraffes mostly consume broad-leaved deciduous foliage during rainy seasons and evergreen plants during other times of the year.
Therefore, The short-neck giraffes would die out because the long-neck giraffes are better fit for that environment.

Where do the substrate and enzyme meet?
Answer:
The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place). A substrate enters the enzyme's active site. This results in the formation of the enzyme-substrate complex.
Explanation:
An enzyme will grip (bind) to one or more reactant molecules to catalyze a process. These are the substrates of the enzyme. Different enzymes have varying degrees of selectivity, or "pickiness," about which molecules may be employed as substrates. Some enzymes exclusively take one type of substrate and will not catalyze a reaction even though it is extremely closely related. Other enzymes can function on a variety of target molecules as long as they possess the sort of bond or chemical group that the enzyme is looking for.In certain reactions, a single substrate is degraded into several products. In others, two substrates combine to form a bigger molecule or to swap components. In fact, each form of biological reaction you can think of has an enzyme to accelerate it up!
The region of the enzyme where the substrate attaches is known as the active site (since it is where the catalytic "activity" takes place).
Proteins are made up of amino acid units, and the active site in protein enzymes receives its features from the amino acids it's made up of. These amino acids can have big or small side chains, acidic or basic side chains, hydrophilic or hydrophobic side chains.
The amino acid sequence present at the active site, as well as their placements in 3D space, give the active site its distinct size, shape, and chemical activity. Because of these amino acids, the active region of an enzyme is specially designed to attach to a specific target—the enzyme's substrate or substrates—and assist them in undergoing a chemical process.

Which two types of energy need water to work
There are four types of water energy and they are:
Thermal power plants: Steam is used in thermal power plants for the generation of electricity. Pressurized water vapour is used for the running of turbines on the power plants which generates electricity.
Geothermal energy: Here, the water is heated from the inside the Earth for the creation of steam. There are times when steam rises naturally to the surface which is harnessed for the generation of electricity.
Hydropower: Electricity is generated by running water falling from a distance on the turbines. Water is stored in the reservoirs which have potential energy and are released from a lower elevation. This energy is used for the generation of electricity.
Tidal energy: Tidal energy is obtained from the tides created in the ocean. Also, tidal energy is one of the renewable sources of energy.
