The figure here represents that the oxygen is being taken up by the red blood cells in the lungs and will be transported to the whole body.

In return the carbon dioxide diffuse into the blood capillaries and is carried back to the lungs to get exchanged by oxygen.

This process of exchange of gas is called as respiration.

Increasing emission of carbon dioxide, resulting primarily from the burning of fossil fuels, leads to global warming by enhancing Earth's natural greenhouse effect. This has caused significant climate change, including raised global temperatures, altered weather patterns, and potentially catastrophic impacts on biodiversity.

Carbon dioxide emissions are radically affecting Earth's natural cycle of temperature change through a process known as the greenhouse effect. This involves greenhouse gases like carbon dioxide absorbing and emitting radiation, which traps heat in Earth's atmosphere leading to global warming. The burning of fossil fuels has caused carbon dioxide levels in the Earth's atmosphere to increase drastically, now reaching unprecedented levels in human history.

This increase in CO2 concentration is directly linked to a rise in global temperatures. Evidence supports the relationship between atmospheric concentrations of carbon dioxide and temperature: as carbon dioxide rises, global temperature rises as well.

Important consequences of these changes include global climate change resulting in altered weather patterns including a worldwide temperature increase. Potential impacts of such changes can be catastrophic for many species, leading to biodiversity loss, and posing significant threats to both industrial civilization and the ecology of our planet.

Explanation:

An ecological pyramid refers to a graphical demonstration created to show the bioproductivity or biomass at each of the trophic levels in a given ecosystem. The energy pyramids initiate with the producers like plants at the bottom and advance via the various trophic levels, the highest level is the top of the food chain.  

A pyramid of productivity is generally more beneficial, demonstrating the turnover or production of biomass at each trophic level. Rather than demonstrating a single snapshot in time, productivity pyramids demonstrate the energy flow via the food chain.  

When energy flows to the next trophic level, generally only 10 percent of it is used to construct new biomass, turning into stored energy. In the pyramid of productivity, each step will be 10 percent of the size of the previous step.

The splitting of water to release hydrogen ions and electrons occurs during the 'light-dependent process' of photosynthesis, which uses 'visible light' from the electromagnetic spectrum to convert solar energy into chemical energy.

The correct option is 'A' & 'I'.

The process of splitting water to release hydrogen ions and electrons occurs during the light-dependent process.

This part of photosynthesis involves the photolysis of water, which is a critical step in the light-dependent reactions where sunlight is used to split water molecules into hydrogen ions, electrons, and oxygen.

Photolysis is crucial as it provides the electrons needed to replace those lost by chlorophyll in photosystem II, and it contributes to the buildup of hydrogen ions inside the thylakoid membrane, which is essential for ATP synthesis.

The section of the electromagnetic spectrum used for photosynthesis is visible light.

Photosynthetic pigments, such as chlorophyll, absorb certain wavelengths within this range to initiate the light-dependent reactions, converting solar energy into chemical energy in the form of ATP and NADPH, which are then used in the light-independent reactions. These energy carriers are vital for driving the Calvin cycle, ultimately leading to the synthesis of sugars.

The given question is incomplete, the complete question is :

"The process of splitting water to release hydrogen ions and electrons occurs during the _____ process.

A. light dependent

The term for the ability of organisms to operate within specific environmental ranges is homeostasis, which includes mechanisms such as thermoregulation. Some life stages, like spores and seeds, exhibit extreme tolerances as a survival strategy, employing adaptations like suspended animation.

The word that describes the ability of organisms to function within a specific range of temperatures, salinities, or rainfall amounts is homeostasis. Homeostasis is the regulatory process through which organisms maintain internal conditions within a narrow range, despite changes in their external environment. This includes thermoregulation, which is the ability to regulate body temperature. For instance, polar bears have adapted structures like fur and blubber to conserve heat in cold climates, while other organisms, like humans and dogs, use perspiration and panting to release excess body heat in hot climates. Moreover, some organisms, known as extremophiles, have evolved to thrive in extreme conditions, such as high temperatures in geysers.

Notably, extreme tolerance to a range of environmental factors, such as temperature, is often associated with certain life cycle stages, like spores and seeds, facilitating survival through unfavorable conditions. This state of suspended animation involves several adaptations, such as energy and carbon reserve accumulation, membrane restructuring, protein structure changes, and, in some cases, cell wall thickening.

Because the collagen provides support and elasticity to connective tissue, such as cartilage, bones, tendons and ligaments.

Collagen is the largest protein in a human body, made up of thousand amino acids. It  builds connective tissues through out the body to support joints, muscles and to rejuvenate the skin.

Some connective tissue diseases and other diseases, mainly because of a weak immune system, can cause the collagen to degenerate. One of them is rheumatoid arthritis which affects the joints, causing pain, swelling and stiffness in the joints.

Collagen is said to stimulate the growth of new cartilage, which is a thin tissue enveloping the joints. However, cartilage is dependent on collagen so when the body lacks collagen, it causes pain, stiffness and instability of the joints.

The asexual vegetative method be used by strawberries is called 'runners'

Answer:

vegetative propogation

Explanation:

Vegetative propagation or vegetative reproduction is the growth and development of a plant by asexual means. This development occurs as a result of fragmentation of a part of the plant or the growth of specialized vegetative parts. Vegetative propagation involves reproduction through vegetative (non-sexual) structures, while sexual propagation is accomplished through gamete production and fertilization.

An example of this can be seen in the question above, where strawberry plants usually reproduce by making corridors, which are miniature versions of themselves, that grow from their parents' roots and stems.

When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy. Plants use water, carbon dioxide, and sunlight to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Chloroplasts in plant cells get energy from sunlight through a process called photosynthesis. This process involves the absorption of light energy that excites electrons in a molecule called chlorophyll, triggering reactions which convert carbon dioxide and water into glucose - a form of energy cells can use.

Chloroplasts are organelles in plant cells that carry out a process called photosynthesis to get energy from sunlight. The process begins when the chloroplast absorbs light energy from the sun. This energy excites electrons within a molecule in the chloroplast called a chlorophyll. The excited electrons then initiate a series of reactions which result in the conversion of carbon dioxide and water into glucose and oxygen. Glucose is then used as an energy source by the plant. In essence, photosynthesis converts energy from the sun into chemical energy that cells can use.

Cell division is the process essential for growth and repair in multi-cellular organisms.

Injury to the tissue can activate surrounding cells to undergo cell division with the help of mitogens. Mitogens are the chemical substances which help in escalating mitotic divisions in the cells.

They act by activating the signal-transduction pathway which involve mitogen-activated protein kinase (MAPK).

Other possible manner could be the loss of density which could lead to the inactivation of contact inhibition. As there is a loss of cells during the injury, it makes an empty space which could also trigger or activate surrounding cell to start cell division.

In addition, at injury site the flow of blood also increases to transport various nutrients, clotting factors, growth factors etc. These increased nutrition and growth factors also speed up the process of mitosis.

Injury to tissue triggers cell division through inflammation and the release of chemical signals and growth factors, which signal surrounding cells to replicate and repair the damage. External events, such as injury and hormone levels, regulate the repair process by promoting the necessary cell division. Fibroblasts and stem cells are essential players in regenerating damaged tissue.

Injury to tissue can prompt cells in the surrounding area to undergo cell division through a process that involves signaling from damaged cells, inflammatory responses, and the action of growth factors. When tissue is injured, resident cells such as mast cells and macrophages release chemical signals that can lead to inflammation, resulting in redness, warmth, swelling, and pain. This inflammation is part of the body's natural healing process. During the repair phase, cells like fibroblasts are critical as they deposit collagen and aid in tissue regeneration. Additionally, external events can regulate cell division. For example, the death of nearby cells or the release of growth-promoting hormones like human growth hormone (HGH) can kickstart the process. Blood capillaries and immune cells help increase circulation and fend off infection, further supporting the healing process. To adequately replace lost or damaged tissue, the stem cells within it must divide to form new cells.

On the molecular level, cell signaling pathways are instrumental in prompting cell division. Cells typically don't divide unless stimulated by signals, often in the form of growth factors binding to cell-surface receptors. These growth factors provide the needed prompts for cells to begin the process of division and replication to repair damaged tissue.

Lastly, cell division is necessary for wound repair. If the surface area that needs repair is extensive, basal stem cells and fibroblasts divide rapidly to recreate the skin and supporting structures. Burn treatment often involves aiding this process through fluid and nutrient support to enable the body's cells to divide and repair tissue.

To reduce pesticide use on a farm, incorporating b) beneficial insects for biological control and implementing conservation tillage and buffer strips can be effective strategies.

To reduce the need for pesticides on his farm, a farmer can employ several methods. Integration of b) beneficial insects is one practice which allows farmers to naturally manage pest populations by using organisms that prey upon and destroy pest species. This is known as biological control and is effective at maintaining lower levels of pests without harming beneficial species. Additionally, conservation tillage can be used to minimize soil disturbance and reduce erosion, while leaving crop residue that may sometimes provide habitat for pests, so it must be managed carefully. Planting buffer strips of grass or trees around fields can also be an effective way to prevent pesticide drift and provide habitats for natural pest enemies.

While conservation tillage and planting certain vegetation can contribute to overall farm health, using biological control through beneficial insects specifically targets the reduction of pests without the need for chemical pesticides.

To change an object's motion, a net external force must be applied, causing an acceleration. For directional changes, the force must be at an angle to the velocity. These phenomena are explained by Newton's laws of motion.

In order for an object to change its motion, which is known as experiencing an acceleration, there must be a net external force applied to the object. If we break this down, first, we must understand what we mean by a change in motion. A change in motion is synonymous with a change in velocity, whether that be a change in speed, direction, or both. According to Newton's first law, an object will maintain its state of motion, be that at rest or in uniform motion, unless it is acted upon by an external force. Thus, a force must cause an acceleration, either in the form of a change in the object’s speed or in a change in its direction of motion.

Specifically, for a change in the direction of motion, the force applied and the velocity of the particle must not be aligned; they should be at an angle. This is essential because only the component of the force that is perpendicular to the initial direction of motion will change the direction. When considering the energy of an object, to change it, a force must at least partially line up with the displacement of the object during the time the force is applied.

The principles behind why and how objects change motion can be encapsulated by Newton's three laws of motion. The first law has already been discussed above, but to recap, 1. An object in motion will stay in motion unless acted upon by a net external force. According to the second law, 2. Force equals mass multiplied by acceleration (F = ma). The third law states that 3. Every action has an equal and opposite reaction.
