Answer:
Cellular respiration is related to breathing because breathing provides compulsory oxygen for the process of cellular respiration to happen and cellular respiration is a process where cells obtain energy. In time of inhalation, the oxygen molecules are necessary for cellular respiration. During the exhalation process, the CO₂ that is produced by cellular respiration leaves the body via nose or mouth. Breathing and cellular respiration are critically important because without either one of the processes, the other cannot take place
Explanation:
Answer:
Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.

what happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?
A) they strengthen each other
B) they negate each other
C) they triple the strength of each other
D) they weaken the power of each gradient by half
Answer:
Option B, they negate each other
Explanation:
Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.
Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
Option B
Answer:
B) they negate each other
Explanation:
The combined effects of electrical and chemical gradients lead to the formation of an electrochemical gradient. This simply means that both an electrical gradient and a chemical gradient can have an effect on the movement of substances, and that their effects may combine (the chemical and electrical gradients encourage movement in the same direction), or they may negate (one gradient opposes another).

when an ecosystem moves from primary to secondary succession of plant species, which most likely declines?
Final answer:
In secondary succession, early pioneer species such as grasses and mosses decline as intermediate species like shrubs and small trees take over and eventually move towards a mature climax community.
Explanation:
When an ecosystem moves from primary succession to secondary succession of plant species, the types of species that most likely decline are the early pioneer species such as grasses and mosses. Secondary succession occurs in an area where a disturbance has occurred, leaving the soil intact. This soil retains nutrients that allow for rapid recolonization by various plant species. Over time, as intermediate species like shrubs and small trees establish themselves, they change the microenvironment and outcompete the early pioneer species, leading to their decline.
The transition from the early fast-growing, sun-loving pioneer species to more shade-tolerant intermediate species results in a shift in the plant community structure. The pioneer species are adapted to conditions of full sunlight and disturbed soil; however, as the intermediate species grow taller and create more shade, conditions become less favorable for these sun-loving plants.
Consequently, there is a marked decline in these species as the ecosystem moves towards a climax community, characterized by a stable and mature community of plants and trees typical of the particular region and climate.

1)Clouds return the water in the cycle when it?
A)rains
B)condenses
2)evaporated water forms into?
A)mist
B)clouds
3)the first step of the water cycle is that water ____into the air
A)condenses
B)evaporates
Pls ❤️
The answers to the questions are as follows:
1) Clouds return the water in the cycle when it A) rains.
2) Evaporated water forms into B) clouds.
3) The first step of the water cycle is that water B) evaporates into the air.
1) The water cycle involves several stages, one of which is the formation of clouds. Clouds are formed when water vapor in the air condenses into tiny droplets or ice crystals. This process typically occurs when air cools to its dew point, and the water vapor can no longer remain in a gaseous state. However, the question asks when clouds return the water in the cycle. This happens when the water droplets or ice crystals in the clouds become too heavy and fall to the ground as precipitation, which includes rain, snow, sleet, or hail. Therefore, the correct answer is A) rains.
2) When water evaporates from the Earth's surface, it turns from a liquid to a gas (water vapor). This water vapor rises into the atmosphere and cools, leading to condensation. The condensed water vapor forms tiny droplets that cluster together to form clouds. Therefore, the correct answer to the question about what evaporated water forms into is B) clouds.
3) The water cycle begins with the evaporation of water from the Earth's surface, which includes oceans, lakes, rivers, and even soil. The sun's energy causes water to change from a liquid to a gas, a process known as evaporation. This is the first step in the water cycle, where water B) evaporates into the air. Once in the atmosphere, water vapor can condense to form clouds, which eventually lead to precipitation, falling back to the Earth's surface to continue the cycle.

Teddy is explaining to his class that hydrothermal vents form isolated ecosystems. Which point should he explain? A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem. B. The organisms of the hydrothermal vent are a part of other food webs. C. There is a continuous input and output of energy and materials in the hydrothermal vent. D. Sunlight plays a vital role in the hydrothermal vent ecosystem.
Answer:
A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem.
Explanation:
An hydro-thermal vent can best be described as an isolated ecosystem or a sort of closed ecosystem. Most of the organisms here do not interact with the larger ecosystem for survival and are not interdependent on them.
In an hydro-thermal vent, life here is supplied with thermal energy that originates from within the crust or the reaches of the core. Since organisms here would thrive regardless of solar radiation, they can produce a sort of localized food web within and would not associate with other ecosystem for survival.
Isolated ecosystems are therefore self-sustaining systems that would not depend on resources from other ecosystems.

Which molecules are used to produce glucose during the calvin cycle?
A. ADP and NADP+
B. ATP and NADPH
C. Chlorophyll and Oxygen
D. Carbon Dioxide and Water
Answer:
B. ATP & NADPH
Explanation:
fruits and vegetables are full of energy. Energy in the form of glucose. The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose.
As Melvin Calvin discovered, carbon fixation is the first step of a cycle. The Calvin cycle transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transport chain, excited electrons lose energy to NADPH and ATP. In the Calvin cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose.
The Calvin Cycle uses ATP and NADPH to produce glucose. These energy carrying molecules are created during the light reactions of photosynthesis.
Explanation:To produce glucose during the Calvin Cycle, the molecules ATP (Adenosine Triphosphate) and NADPH (Nicotinamide Adenine Dinucleotide Phosphate) are utilized. These two molecules are vital energy carriers and are produced during the light reactions of photosynthesis. The energy they carry is used to convert carbon dioxide which is absorbed by the plant into glucose (a type of sugar). For example, substances like Glyceraldehyde-3-phosphate (GA3P) are produced as part of the Calvin Cycle. GA3P is effectively half a glucose molecule and through two cycles of the Calvin Cycle one molecule of glucose is generated utilizing the energy from ATP and NADPH.

What kind of pollution was the most abundant in the US national parks? How did this pollution affect park wildlife and ecosystems?
Answer:
The most prominent kind of pollution during 1989 was air pollution, as several of the country's national parks were hiding behind the air pollution curtains. The pollution started to decline biodiversity as various species were vacating the polluted regions for the cleaner ones, as they were not able to thrive in such circumstances. Due to this some plants even died like Jeffrey pine trees in Sequoia. The biological diversity was at threat as scientists had observed that acid rain and ozone depletion were making the things even worse.
The most abundant pollution in US national parks has been air and water pollution due to industrialization, increased population, and urbanization. This pollution affects aquatic life and can lead to 'dead zones', the reduction of biodiversity, and habitat destruction. Air pollution contributes to the deterioration of air and soil quality, causing harm to both animal and plant life.
Explanation:The most abundant pollution in the US national parks has historically been a mix of air and water pollution. Industrialization, increased population, and urbanization have been the major sources of this pollution. In fact, in 1969, water pollution was so dire that the Cuyahoga River in Ohio actually caught fire.
These forms of pollution have significant impacts on park wildlife and ecosystems. Pollutants in the water can harm aquatic life, creating 'dead zones' unable to support life. As these pollutants travel up the food chain, they can harm predators that consume the affected organisms. Over time, the accumulation of water and air pollution can lead to habitat destruction and reductions in biodiversity.
In the case of air pollution, elements like lead and other harmful chemicals from the burning of fossil fuels can contaminate the air and soil, leading to the degrading health of both animals and plant life. The impacts of these forms of pollution are long-lasting and damage the natural beauty of these protected areas.

Why is heating and cooling necessary when doing the pcr method?
A PCR is used to amplify DNA. The heating breaks the hydrogen bonds and ensures that the double-stranded DNA helix is melted such that the two strand separate. The cooling ensures that the introduced DNA primers bind with the single strands so that elongation of the chain (to form a new double helix) can be possible by DNA polymerase.
what is the process of photosynthesis???
Answer:
The process of photosynthesis is when plants take in co2, sunlight and water which it needs to live. and it gives out oxygen and its food glucose
Explanation:
Answer:
Photosynthesis is the process with which plants transform sunlight into nutrients. It takes place within the thylakoids membrane and stroma of the plant’s chloroplast.
Photosynthesis can be broken down into 2 reactions:
1.) Light-dependant reaction- reaction that requires sunlight and occurs in the thylakoids of the chloroplast.
Reactants: H2O (water), sunlight, NADP+, ADP, and +Pi —> Products: O2, ATP (energy), and NADPH.
2.) Light-independent reaction (aka Calvin Cycle)- reaction that occurs in the stroma of the chloroplast and does not require sunlight because ATP (energy) was formed in the previous reaction.
Reactants: CO2, ATP (energy), and NADPH —> Products: CH2O, NADP+, ADP, +Pi
SO the main reactants of photosynthesis are Light, H2O (water), and CO2 —> the main products of photosynthesis are O2 and CH2O
