is their control or constant variable?
the type of insulation
the temperature of the coffee
the type of coffee cup
The students conducting the experiment

Large areas on the leaves of some plants lack chlorophyll and are therefore not green in color. How does this most likely affect photosynthesis? Not enough sunlight is captured in these areas of the leaves. Carbon dioxide cannot enter these areas of the leaves. Too much glucose builds up in these areas of the leaves. Oxygen cannot be released in these areas of the leaves.

Answers

(Not enough sunlight is captured in these areas of the leaves)

The plants are of green color due to the pigment chlorophyll. the chlorophyll plays a crucial role in photosynthesis, the process of preparing food.

The correct answer is:

Option A. Not enough sunlight is captured in these areas of the leaves.

The functioning of chlorophyll can be explained as:

Chlorophyll is the green color pigment present in the chloroplast of the leaves. The pigment is involved in the capturing of sunlight and imparting green colors to the plants.

The plants lacking chlorophyll will not be able to perform photosynthesis. The process of preparing food in the presence of sunlight, chlorophyll, and carbon dioxide. The products of photosynthesis are oxygen and sugar molecules.

Thus, the correct answer is Option A.

Explanation:

Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light.

After Pedro had breakfast, he went for a run. Identify at least three energy transformations that had to take place to allow Pedro to complete his run. Then use evidence to support the claim that energy in this system was conserved as it was transformed.​

Answers

I tried my best to answer.

1) Chemical to mechanical (calories -> muscle contractions)
2) mechanical to mechanical (muscle -> motion)
3) mechanical to thermal (motion -> heat from the body causes sweating)

The potential energy is stored in the body chemically (via food). That potential energy is then released when the body is put in motion.

Answer:

When Pedro ate breakfast, he consumed chemical energy. Chemical energy is a form of potential energy and that potential energy was stored in his breakfast. When he went out for a run, the chemical energy transformed into mechanical energy, which is a form of kinetic energy. The mechanical energy then transforms into thermal energy when he is running. While running his temperature started to rise which caused him to sweat. The energy in his system was conserved as it was transformed because the energy was constant. When the energy was being transformed between different types, the total amount of energy remained the same.

In this case, regarding the molecules:

NH₄⁺, NH₃ and NH₂⁻.

Which are ammonium, ammonia and amide, in order to rank them in terms of how big the angles are, we need their molecular geometry as shown on the attached picture. As you can see, the geometry of ammonium is tetrahedral with an angle between H bonds of 109.5°, the geometry of ammonia is trigonal pyramidal with an angle between H bonds of about 107° and the geometry of amide is bent with angles of 104.5°.

Therefore the order from smallest to biggest is: NH₂⁻<NH₃<NH₄⁺.

amaging a world without plants. will it be different world. think and write two lines on this​

Answers

It will definitely be a different world because they support natural and human food systems and provide homes for countless species including us, through building materials. Yet we often treat trees as disposable: as something to be harvested for economic gain or as an inconvenience in the way of human development. Since our species began practicing agriculture around 12,000 years ago, we’ve cleared nearly half of the world’s estimated 5.8 trillion trees.

Life could not exist on Earth without trees because they produce most of the oxygen that humans and wildlife breathe. Trees absorb carbon dioxide from the atmosphere and release oxygen using the process of photosynthesis. There would also be no rain without trees since trees absorb water from the soil and release it through evapotranspiration. Water vapor released through evapotranspiration is the major mechanism by which air is remoistened. Forests act as giant air filters for the world. Trees purify the air by absorbing pollutants such as sulfur dioxide and nitrogen dioxide, reducing pollution. Trees also help prevent topsoil erosion because they break the force of wind and rain on soil, their roots bind the soil, and their decayed, falling leaves are absorbed by the earth and enrich the soil. Trees conserve rainwater and reduce water runoff and sediment deposit after storms.Additionally, trees provide a supply of lumber, seeds, and fruit. Further, dead trees that fall and get

Answer:

System that receives and transmits information and responses, in addition to work with electrical  impulses is the Nervous system.

Explanation:

The nervous system (NS) is responsible for the control of all the organs and functions of the body. The neuron is the functional unit of this system, allowing the transmission of information through nerve impulses, generated by the difference in potential of its cell membrane.

NS is divided into:  

Central nervous system (CNS) —where the brain, spinal cord and other structures are located— in charge of receiving, processing and sending information. Peripheral Nervous System (PNS), a network of nerve fibers in charge of receiving the stimuli and conducting the information to and from the CNS.

The integration of both NSC and NSP allows an organism to fulfill all its functions, both voluntarily and involuntarily.

Which path shows how gravity causes water to move?(APEX)

Answer:

Stream , Tributary, River, and Lake

Explanation:

Stream tributary River and Lake is the path for gravity causes water to move.

What is Path for water?

Evaporation, condensation, and precipitation are typically taught as three separate but interconnected stages of the water cycle. Although this is a useful model, the actual situation is far more nuanced.

Water moves through ecosystems on Earth in a variety of ways that are incredibly complicated and still not fully understood.

For better weather, climate, water resource, and ecosystem health forecasting, NOAA is working to increase understanding of the water cycle at all sizes, from the global to the local.

Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle. This is a good paradigm, but in practice things are much more nuanced.

Therefore, Stream tributary River and Lake is the path for gravity causes water to move.

Under normal conditions, gases diffuse through small holes in the leaves of a plant. When the weather is very hot and dry, plants may close these openings to conserve water. How are the closures most likely to affect photosynthesis? O They increase the rate of photosynthesis by increasing the amount of water in the leaf They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf They increase the rate of photosynthesis by increasing the amount of oxygen in the leaf They have little or no effect on photosynthesis because gases do not take part in the process​

Answers

Answer:

They increase the rate of photosynthesis by increasing the amount of water in the plant.

Explanation:

It is hot and dry when these openings close, so the Sun has to be out. Photosythesis is caused when the Sun and water are used by a plant to make food.

The answer to the question should be they increase the rate of photosynthesis by increasing the amount of water in the plant.

A diagram of photosynthesis is below.

The closures that are most likely to affect photosynthesis are they increasing the rate of photosynthesis by increasing the amount of water in the plant. The correct option is A.

What is photosynthesis?

Photosynthesis, the method used by plants and other autotrophic organisms to make food, converts carbon dioxide into glucose and oxygen, both of which are vital for life.

Photosynthesis depends on some factors. These factors are water, sunlight, and carbon dioxide. If there is a scarcity of any factors, it impacts the process of photosynthesis. If the water does not get enough water, it will dry and there is less chlorophyll for the plant to carry out photosynthesis.

Therefore, the correct option is A. They increase the rate of photosynthesis by increasing the amount of water in the leaf.
