Answer:
Going by the definition, pioneer species are hardy species which establish themselves in a disrupted ecosystem and trigger the process of ecological succession. These include species like algae, lichens, and mosses, which grow in poor, nutrient-deficient soil, and put up with extreme conditions with immense ease. Most pioneer plants are annuals, i.e., species with a life-cycle of a year, which eventually give way to the emergence of perennials.

Which of the following was the major contribution made by Avery, MacLeod, and McCarty that strengthened the argument that the transforming agent in Griffith's experiment was DNA? Multiple Choice Transformation of nonvirulent cells with a DNA extract was successful when DNase was added. Transformation of nonvirulent cells with a DNA extract was blocked only if protease was added. Transformation of nonvirulent cells with a DNA extract was blocked only if RNase was added. Transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added.
The major contribution made by Avery, MacLeod, and McCarty was 'transformation of nonvirulent cells with a DNA extract was blocked only if DNase was added'. This observation supported the idea that the transforming agent in Griffith's experiment was DNA.
The Avery–MacLeod–McCarty experiment showed that DNA was the transforming agent observed in Griffith's experiment.
Griffith's experiment (1928) suggested that bacteria were capable of transferring genetic information (DNA) by a process of horizontal gene transfer called transformation.
While the bacteria were killed by heat, Frederick Griffith observed that the DNA had was taken up by II-R strain bacteria via transformation.
Avery–MacLeod–McCarty experiment observed that protease enzymes did not destroy the transforming agent (but DNAse destroyed this transforming principle), thereby suggesting that the transforming agent in Griffith's experiment was bacterial DNA.

What is cellular respiration?Cellular respiration is a biochemical process that disintegrate glucose to generate ATP, which can then be used as energy to power a variety of reactions all through the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cellular respiration is the process by which organisms (animals and plants) break down sugar in the presence of oxygen in order to release energy in the form of ATP. As a byproduct of this process, carbon dioxide and water are produced.
Cellular respiration reactions are classified into three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and electron transport chain.
The correct option is D.

interact to maintain homeostasis?
Explanation:
through its receptors, the nervous system keeps us in touch with our environment. The portion of the brain that maintains the body's internal balance (homeostasis). The hypothalamus is the link between the endocrine and nervous systems. The hypothalamus produces releasing and inhibiting hormones, which stop and start the production of other hormones throughout the body
How do you think scientific method can be used to measure the rate of photosynthesis
Answer:
Uptake of CO2 by plants: Since CO2 is needed for photosynthesis, measuring how much of it is taken up by the plants gives us information on how much of photosynthesis is happening.
Release of O2: The amount of O2 produced during photosynthesis can be measured.
Dry matter content: Dry matter is comprised of all the solids in a plant minus the water content. These solids are all produced as a result of photosynthesis. So, dry matter can be used to measure this process.
Carbohydrate production: This is an indirect way of measuring photosynthesis by its products. Parts of a plant can be harvested, dried and weighed at intervals. The difference in weights gives the increase in carbohydrates (sugars) due to photosynthesis.
Measure light-dependent photosynthesis using Hill’s reaction: In the first step of photosynthesis, oxygen is produced by chloroplasts by splitting water molecules using energy from light. Using dichlorophenolindophenol (DCPIP) as the terminal electron acceptor of oxygen atoms, Hill’s reaction measures the light-dependent phases of photosynthesis.
Chlorophyll fluorescence: When chlorophyll absorbs light, its molecules are raised to an “excited state”. It returns to its normal state by releasing the energy. Part of this is used to power photosynthesis; another portion is emitted as radiation called flourescence radiation. Since flourescence radiation is complementary to photosynthesis it is used to measure it in higher plants as well as algae and bacteria.

Describe the structure of a capillary and the transfer of a named material between capillaries and tissue fluid
Answer:
Explanation:
Normally, the hydrostatic pressure difference between capillary fluid and interstitial fluid favors movement of fluid out of a tissue capillary. The protein osmotic pressure difference between capillary fluid and interstitial fluid normally favors movement of fluid into a tissue capillary. As pressure exerts force, Hydrostatic pressure is a type of force that occurs in fluid e.g (interstitial fluids) on the walls of the capillary. The helps to carry fluid-like materials out of the tissue capillary. There are quite bunch of relative factors affecting the hydrostatic pressure which include; the liquid density and distance beneath the liquid surface,force of gravity.
On the other hand, The protein osmotic pressure difference between capillary fluid and interstitial fluid normally favors movement of fluid into a tissue capillary. This protein substances consist of albumin, plasma protein etc. From our knowledge of osmosis as well, we knew it is the movement of substances through a semi-permeable membrane from the region of higher concentration to a lower concentration. Therefore the protein osmotic pressure bring about movement of fluid like substances into the tissue capillary.
Capillaries due to their thin membrane, enables oxygen diffuses from the blood into the cytoplasm of cells.
What is a blood capillary?A blood capillary is a very thin-membrane vessel which occurs as a result of fine branches from arteries and veins.
Capillaries are responsible for the transfer of oxygen and carbon dioxide between the blood and cells.
Due to its thin membrane, oxygen diffuses from the blood into the cytoplasm of cells.
Therefore, capillaries enable the transfer of gases between the blood and tissues.

Which macromolecule contains the most-dense source of energy for ATP production?
Answer:
Lipids store the most chemical potential energy. Carbohydrates are more readily available though so the body use carbs when it can before accessing lipid storages.
Proteins have some potential for making ATP but your body needs proteins to actually make the ATP and stuff so ideally you'll never really be burning protein for energy; rather it gets broken down and used for parts in machinery.
