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.

Explanation:

Photosynthesis is the process by which plants, some bacteria and some protistans use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

Photosynthesis uses sun energy to convert carbon dioxide and water into glucose and oxygen. The additional product of this process, apart from glucose, is oxygen.

In the process of photosynthesis, energy from sunlight is used to rearrange the atoms in carbon dioxide and water to produce glucose, a type of sugar. However, glucose is not the only product of photosynthesis. Another substance also comes out of this process: oxygen. According to the general photosynthetic equation 6CO₂ + 6H₂O + light energy --> C6H12O6 + 6O2, six molecules of carbon dioxide (CO2) and six molecules of water (H2O) react under light energy to produce one molecule of glucose (C6H12O6) and six molecules of oxygen (O2). Therefore, the correct answer to your question is Oxygen.

Largely, the rise in oxygen in our atmosphere allowed for life to grow and survive.

Significant events that contributed to the evolution of life on Earth include oxygenation of the atmosphere, mass extinctions, climate and geographic changes, and natural selection, which all played roles in creating the conditions for diverse life forms to emerge and evolve.

The evolution of life on Earth has been shaped by various planetary events. Among these, significant contributors to the evolution of life include the oxygenation of the atmosphere, which created conditions suitable for the evolution of aerobic organisms and subsequently eukaryotes. Planet-wide changes such as mass extinctions, caused by events like asteroid impacts, have dramatically reshaped life by wiping out dominant species and allowing others to flourish, leading to an increase in diversity. Further, changes in climate and geography have played a critical role in life's evolution, as seen during periods like the Cambrian explosion which led to a rapid diversification in life forms. The ongoing process of natural selection also continually influences the trajectory of evolution as species adapt to their changing environments.

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.

Answer;

Bones

Explanation;

The x-ray particles pass through the body.  Structures that are dense such as bone will block most of the x-ray particles.

Different parts of the body absorb the x-rays in varying degrees. Dense bone absorbs much of the radiation while soft tissue, such as muscle, fat and organs, allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray and air appears black.

pleiotropy

hope this helps :)

Answer:

The correct answer is pleiotropy.

Explanation:

The kinds of genes that affect and influence more than one character or trait are known as the pleiotropic genes. This phenomenon is known as pleiotropy or pleiotropism. An illustration of pleiotropy is sickle cell disease or sickle cell anemia. In a specific homozygous condition that is, HbS and HbS, the gene for sickle-cell anemia is lethal, while the generation of sickle cell trait occurs in heterozygous condition, that is, HbA and HbS.

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.  

Answer:

(D). Archaea.

Explanation:

Archaea are single-celled, prokaryotic organisms that can survive in extreme conditions. Archaea that live in environments with extreme salt concentrations are known as halophiles.

Archaea use bacteriorhodopsin, a protein which helps in photosynthesis. It helps in capturing energy from light and converts it into chemical energy in the form of ATP molecules.

Thus, the correct answer is 'option (D).'

In my opinion I feel that because when two human beings create another they share their genes with the new human being. As that human grows up it does the same thing. It's known as a cycle. I'm guess that there will be a time where two healthy people will decide to reproduce and will create a healthy baby. Although I'm not all sure.

I hope I explained well enough. xD

Sexual reproduction increases genetic diversity due to crossing over and independent assortment during meiosis, creating new combinations of traits in offspring.

Sexual reproduction greatly contributes to genetic diversity among a population. This is mainly due to two biological processes: crossing over and independent assortment.Crossing over is a process that occurs during meiosis, where sections of DNA are exchanged between two chromosomes. This process creates new combinations of genes, increasing the variety of traits within the offspring.

Independent assortment also happens during meiosis, it refers to the random assortment of chromosomes during the formation of sex cells or gametes. This further increases the possible number of gene combinations in the offspring.

These mechanisms, combined with the natural process of mutation, contribute to the high levels of genetic diversity that are achieved through sexual reproduction.

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.

Option C is the correct option. Which is, "Carbon forms covalent bonds with other carbon atoms".

Carbon's ability of catenation  makes it unique and suitable for the formation of macromolecules.

Catenation is the Characteristic of atoms of the same element to form longer chains. Catenation occurs most readily in carbon, which forms covalent bonds with other carbon atoms to form longer chains and structures. This is the reason for the presence of the carbon in all organic compounds.

The answer is eliminated as heat.

Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.

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 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.

Answer:

B.)

Explanation:

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.

The correct answers are:

- is the innermost layer;

The troposphere is the first layer of the Earth's atmosphere, thus it is the innermost one of all. This is the layer which enables life on our planet, and its composition is just the right one that life on Earth can thrive.

- has the highest air pressure;

Because this layer has the biggest density of all layers, which practically means that it has the most molecules per area, so it is the richest with gasses, this layer has the highest air pressure. The more gasses there are in a layer, the heavier it is, thus it has bigger air pressure.

The troposphere is the innermost layer of Earth's atmosphere, extends about 12 km above the surface, and contains the highest air pressure of all atmospheric layers. It is a suitable place for planes to fly but does not contain the ozone layer.

The troposphere is the innermost layer of the Earth's atmosphere, extending approximately 12 km above the Earth's surface, though it can vary depending on the location and the season. Therefore, the statements indicating it as the innermost layer and its span are correct. The troposphere is also characterized by having the highest air pressure compared to other atmospheric layers. However, the ozone layer is not located in the troposphere, but in the stratosphere, the layer above the troposphere. Finally, the troposphere is indeed a suitable place for planes to fly due to stable weather conditions and lower altitude.
