Answer: (EXAMPLES). Human body temperature - The hypothalamus of a human reacts to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.

Human blood pressure - When blood pressure increases, signals are sent to the brain from the blood vessels. Signals are sent to the heart from the brain, and heart rate slows down, thus helping blood pressure to return to normal.

Human metabolism - When a human is hungry, metabolism slows down to conserve energy and allows the human to continue living with less food.

Regulation of blood sugar in humans - When blood sugar rises, insulin sends a signal to the liver, muscles, and other cells to store the excess glucose. Some is stored as body fat, and other glucose is stored as glycogen in the liver and muscles.

Production of human red blood cells (erythropoiesis) - A decrease in oxygen is detected by the kidneys and they secrete erythropoietin. This hormone stimulates the production of red blood cells.

Explanation: Since we all know, A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.

Hypothesis for a controlled experiment to determine whether earthworms change the forest ecosystem, The soil's PH will drastically change after the worms consume the leaf litter in a closed container filled with soil.

A number of plots of deciduous forest land would be the subject of an investigation in a controlled experiment to ascertain the effects of the new invasive worm. To make it easier to create artificial ecosystems in a lab, each plot should have boundaries that are limited. There ought to be three main groups: one without any worms, one with only native worms, and one with worms from both native and exotic species. similar circumstances ought to be applied to every individual plot: the same number of trees, the same amount of initial leaf litter, and the same amount of precipitation. The mass of the leaf litter should be taken at the conclusion of the experiment and compared to the initial mass. The plot with the exotic worms is anticipated to have the least amount of leaf litter compared to the other plots. The premise is: The amount of leaf litter that remains at the end of a season in a plot with only the native worm species will be significantly less if an exotic worm species is introduced into a deciduous forest ecosystem. To guarantee accurate results, multiple trials should be carried out.

A filter chamber is an adaptation seen in the mouthparts of mosquitoes. Mosquitoes have specialized mouthparts that are adapted for piercing the skin of their hosts and feeding on blood.

The mouthparts consist of several structures, including a pair of mandibles, a pair of maxillae, and a hypopharynx. The hypopharynx is modified in female mosquitoes to form a filter chamber, which allows the mosquito to separate blood plasma from blood cells and other components. The filter chamber in female mosquitoes is lined with fine, hair-like structures known as microtrichia, which help to filter the blood and prevent larger particles from entering the mosquito's digestive system. The filtered plasma is then ingested by the mosquito, while the remaining blood components are excreted

The filter chamber is an important adaptation that allows female mosquitoes to feed on blood and obtain the nutrients they need for egg development. Without this adaptation, mosquitoes would not be able to survive and reproduce.

According to the principle of superposition, the oldest sedimentary rock units are at the bottom and the youngest are at the top.

What are sedimentary rocks?

Sedimentary rocks are rocks formed by the accumulation of sediment that is cemented together. These rocks are formed when sediments are compacted and lithified (hardened) by the pressure of overlying material. They are typically composed of layers, or strata, created as a result of deposition of the sediments. Examples of sedimentary rocks include sandstone, limestone, shale, and conglomerate.

The bottom layer of rock forms first, so it is the oldest. Each layer above that is younger, with the top layer being the youngest.

Decomposers play an important role in maintaining the health and balance of an ecosystem. They break down dead organic matter such as dead plants and animals, and convert them into nutrients that can be absorbed by other living organisms.

This helps prevent the accumulation of dead matter in the ecosystem, which could lead to a buildup of harmful bacteria and disease. Additionally, decomposers restore essential nutrients such as carbon, nitrogen, and phosphorus back into the soil, which is important for the growth of plants. Unlike producers, which use sunlight to create their own food, decomposers consume organic matter to produce energy for themselves and to recycle nutrients back into the ecosystem.

In summary, decomposers are essential in ensuring the overall health and productivity of an ecosystem by breaking down dead matter and returning valuable nutrients back to the environment.

In this exercise, amoeboid organisms exhibit a characteristic shape-changing appearance and a slower rate of locomotion compared to flagellated and ciliated organisms, which display more defined structures and faster movement.

Amoeboid organisms, such as amoebas, have a flexible, fluid-like body shape that allows them to extend pseudopods and change their shape as they move. They exhibit a characteristic amoeboid appearance, with constantly changing extensions and retractions. Their mode of locomotion is generally slower compared to flagellated and ciliated organisms.

Flagellated organisms possess whip-like appendages called flagella that propel them through their environment. Flagella provide a more defined and coordinated form of locomotion, allowing for faster movement and directed swimming.

Ciliated organisms have numerous hair-like structures called cilia on their surface. These cilia beat rhythmically in a coordinated manner, creating wave-like movements. Cilia enable these organisms to move with greater precision and speed, allowing for efficient locomotion and movement of fluid or particles over their surface.

Overall, amoeboid organisms exhibit a distinct appearance with shape-changing capabilities but have slower locomotion, while flagellated and ciliated organisms have more defined structures and display faster, more coordinated movement.

Photosynthesis in chloroplasts involves major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation. It begins with light-dependent reactions in photosystems I and II, followed by electron transport and ATP synthesis.

Step 1: Photosynthesis is a complex process that occurs in the chloroplasts of plants, involving several major steps such as light absorption, electron transport, ATP synthesis, and carbon fixation.

Step 2:Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. It occurs in the chloroplasts, specifically in three main stages: light-dependent reactions, electron transport chain, and the Calvin cycle.

During the light-dependent reactions, light energy is absorbed by chlorophyll molecules in photosystem II (PSII) and photosystem I (PSI). In PSII, water molecules are split, releasing electrons, protons (H+ ions), and oxygen. The electrons move through an electron transport chain, creating a proton gradient across the thylakoid membrane. This gradient is essential for ATP synthesis by ATP synthase, using the energy from the electron flow.

In PSI, electrons are re-energized by absorbing more light energy and are ultimately used to produce NADPH, another energy carrier. The ATP and NADPH generated in the light-dependent reactions are then used in the Calvin cycle.

The Calvin cycle, also known as the light-independent reactions or carbon fixation, occurs in the stroma of the chloroplast. It uses ATP, NADPH, and carbon dioxide (CO2) to produce glucose (G3P), which serves as a building block for sugars and other organic compounds. The cycle regenerates the starting molecule, ribulose bisphosphate (RuBP), allowing the process to continue.

True. The first meiotic division, also known as meiosis 1, is responsible for reducing the chromosome number in half. This reduction is crucial for sexual reproduction because it ensures that the resulting gametes (sperm or egg cells) have half the genetic material of the parent cell.

The During meiosis 1, the homologous chromosomes pair up and then separate, each going to a different daughter cell. This separation is known as reduction division, and it results in two haploid cells with half the number of chromosomes as the parent cell. Meiosis 2, which follows meiosis 1, is similar to mitosis, with the separation of sister chromatids resulting in four haploid daughter cells. It is important to note that errors during meiosis, such as non-disjunction, can lead to abnormal chromosome numbers in gametes and ultimately result in genetic disorders.
