2. The sugar molecules come from the soil

3. The sugar molecules are one of many sources of food for plants

4. The sugar molecules are made from molecules of water and minerals

Certain environmental changes such as changes in amount of available carbon dioxide as well as amount of sunlight can affect a plant's photosynthetic processes.

There are several environmental changes that affect the rate of photosynthesis. Photosynthesis is the process by which plants produce their own food in the presence of sunlight by the combination of water and carbon dioxide to yield glucose.

There are two main environmental changes that could affect the rate of photosynthesis and these are;

These changes are capable of increasing or decreasing the rate of photosynthesis.

Evidence of Sea Floor Spreading Harry Hess’s hypothesis about seafloor spreading had collected several pieces of evidence to support the theory. This evidence was from the investigations of the molten material, seafloor drilling, radiometric age dating and fossil ages, and the magnetic stripes.

Watson and Crick's model explained mutability because bases pairs can suffer changes (mutations) during DNA replication. Moreover, this model also explained stability because DNA strands are held together by hydrogen bonds.

Deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.

In Watson and Crick's model, both DNA strands are held together by hydrogen bonds between nitrogenous bases on opposite DNA strands, thereby providing stability to the DNA molecule.

In DNA, Guanine always pairs with Cytosine by three hydrogen bonds, while Adenine always pairs with Thymine by two hydrogen bonds.

Moreover, Watson and Crick suggested that mutations could occur as a consequence of a base occurring very infrequently in one of the less likely tautomeric forms during DNA replication, thereby also explaining the mutability of life.

Answer:

Ecosystem Services are the benefits nature provides to human well-being. The term is frequently thrown around in academic circles, but why should you care about them?

Although the term is quite new, our connection to nature is not. We depend on nature for our survival - without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. We also enjoy nature... studies show that people who spend time in nature tend to be happier than those that don’t. It can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the trade-offs we are making between nature and industrial development.

This brings us to the reasons why we feel Ecosystem Services are important to each and every person:

1. Boundless Benefits

Understanding nature in economic terms, while not perfect, allows us to put everything into the same comparison unit. Despite nature being such an integral part of the human existence, it is sometimes an afterthought in today’s economy. Nature and money are often on competing terms, so to make a more level playing field, environmental economists have tried to bridge this gap by placing a monetary value on the benefits nature provides.

A recent study estimated the combined benefits of nature to people at well over $100 USD trillion per year. To put this in perspective, the top 50 most profitable companies globally combine to make just under $10 USD trillion per year.

Valuing nature in a way that can speak to decision makers, may help promote conservation efforts in the future. It brings nature back into the cost-benefit discussion in a way that can be easily understood.

2. The Foundation For Sustainable Development

Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on. Assigning a dollar value to these lakes and forests, and the Ecosystem Services they provide, helps adjust the cost benefit analysis by evaluating the negative effects development will have on the natural environment.

Companies have also started to use Ecosystem Services in conservation offset planning, where they can buy and sell credits to offset a development or set aside land to meet a specific offset. Sustainable development supports the maintenance of a healthy economy while also protecting the ecological process for future generations.

3. Essential For Our Survival

Whether you live in rural Newfoundland or downtown Los Angeles, your dependence on Ecosystem Services is the same. As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry. As the world’s population continues to grow, so too does our dependence on healthy ecosystems to provide the necessities essential to our survival.

Don’t we all want to leave the planet in a good condition for our successors? Ecosystem Services valuation and assessment is one way to help make this happen. By clearly understanding their value, we can make the best and most informed decisions about how to manage our landscape to ensure this value isn’t lost.

Diffusion and osmosis has one difference which is the presence of semi-permeable membrane.

Diffusion is the movement of particles from an area of higher concentration to one of lower concentration while on the other hand, osmosis is the movement of particles from a semipermeable membrane.

Cell membrane is selectively permeable which only allows some molecules inside the cell because of its structure. So we can conclude that diffusion and osmosis has one difference which is the presence of semi-permeable membrane.

When protein molecules were evenly distributed on both sides of the membrane, the solution will be isotonic because of the same quantity on both sided. There is no movement of water in the body.

When protein molecules were more highly concentrated on the inside of the cell than outside of the cell, the solution will be hypotonic because of the less amount of water in the body.

Answer:

- 1). Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.

- 2).

a). A semipermeable membrane allows some substances to pass through it.

b). The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.

- 3).

a). The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.

b). In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.

- 4).

a). The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.

b). In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.

- 5).

a). A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.

b). If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.

Answer:

Living organisms sustain life, based on certain life processes. These life processes help to regulate their daily activities. Excretion is one among them. The metabolism takes place in the cells of living organisms resulting in both useful and toxic products. The accumulation of toxins may harm the organism. Thus, the living organisms remove all these metabolic wastes from their body and this process is called excretion. Different organisms follow different modes of excretion. Let’s have a glance at excretion in plants and how excretion in plants is different from that of animals.
