can anyone tell me which structures are major or accessory structures of the digestive system ?

Answer:

Look at the Eplanation Below.. >>>

Explanation:

The distribution of water is not uniform in both the hemispheres of earth. It is estimated the 43 % of total area covered by water lies in northern hemisphere where as the remaining 57 % lies in the southern hemisphere. About 96.5 % of total water are in the form of ocean . Rest water are present in the form of river ,lake , pond , water vapour etc.

Answer:

Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil. Soil provides plants with foothold for their roots and holds the necessary nutrients for plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater.

Answer:

Mutation followed by natural selection made mosquitos resistant to DEET

Explanation:

Natural selection selects beneficial alleles, which increase their frequency in the population, resulting in adaptation. Aptitude, which is the contribution of each genotype to the next generation, increases too.  

In many cases adaptations, resulting from the natural selection process can be correlated to environmental factors or selective pressures applied by other organisms or habitats.  

Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.

So, in the exposed mosquitos´ example,

Probably some of the mosquitos in the population suffered a mutation that favored them in not detecting repellent DEET. These individuals developed resistance to the chemical and were able to survive and reproduce, enhancing population sizes again. Natural selection benefited the mutation that gave them resistance.

Let us remember that the term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to cause an effect on the insect population.  

Repellents might produce a genetic modification in the insects, leading them to not detect the chemical. Insects evolve with the capability of tolerating the DEET dose that normally is used to repel mosquitos

The excessive use of DEET leads to the fixation of new genes -by natural selection- that result from mutations in the mosquito genetic material, which makes them become even more resistant to the chemical.

Explanation: The Exxon Valdez oil spill was a manmade disaster that occurred when Exxon Valdez, an oil tanker owned by the Exxon Shipping Company, spilled 11 million gallons of crude oil into Alaska’s Prince William Sound on March 24, 1989. It was the worst oil spill in U.S. history until the Deepwater Horizon oil spill in 2010. The Exxon Valdez oil slick covered 1,300 miles of coastline and killed hundreds of thousands of seabirds, otters, seals and whales. Nearly 30 years later, pockets of crude oil remain in some locations. After the spill, Exxon Valdez returned to service under a different name, operating for more than two decades as an oil tanker and ore carrier.

On the evening of March 23, 1989, Exxon Valdez left the port of Valdez, Alaska, bound for Long Beach, California, with 53 million gallons of Prudhoe Bay crude oil onboard.

At four minutes after midnight on March 24, the ship struck Bligh Reef, a well-known navigation hazard in Alaska’s Prince William Sound.

The impact of the collision tore open the ship’s hull, causing some 11 million gallons of crude oil to spill into the water.

At the time, it was the largest single oil spill in U.S. waters. Initial attempts to contain the oil failed, and in the months that followed, the oil slick spread, eventually covering about 1,300 miles of coastline.

Investigators later learned that Joseph Hazelwood, the captain of Exxon Valdez, had been drinking at the time and had allowed an unlicensed third mate to steer the massive ship.

protein pump

Explanation:

This protein pump, also known as the Na+/K+ pump or Na+/K+-ATPase, is located in the cell membrane of neurons (and other animal cells). It works by transporting sodium and potassium ions across the cell membrane in a 3:1 ratio of sodium ions out to potassium ions in.

Answer:

Hello There!!

Answer:

when vesicles cluster at the future plane of division

Explanation:

Cytokinesis is the process whereby the cytoplasm of a cell divides into two. This process of cytokinesis occurs after nuclear division i.e. division of the nucleus. However, cytokinesis differs in plant and animal cells.

In plant cells, the separation of the cytoplasm involves the formation of a cell plate. The process begins when a structure called phragmoplasts carry vesicles to the cell plate. In other words, vesicles cluster at the future plane of division (cell plate).

Explanation:

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = - log [H3O+].

Definition of Photosynthesis

Photosynthesis is the process in which green plants produces their own food.

Answer:

Explanation:

Plants need three things to perform photosynthesis, they are carbon dioxide, water, and sunlight.

Answer:

B. Decomposer

Explanation:

Bacteria and fungi fulfill the role of decomposers in an ecosystem. Hence, option (B) is the correct answer.

Answer:

it's A

Explanation:

It's just a simple chain. Many Organelles form cell, many cells form a tissue, many tissues together form an organ, various organs together form an organ system and different organ systems together make a complete organism.

I hope it helps :))

Answer: If you are asking if your answer is correct, it is. Photosynthesis is the process of converting sunlight into food and energy, therefore it is an example of nutrition.

Photosynthesis in plants is an example of nutrition

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

It is carried out by algae, plants and even some microorganisms.

The sugar produced form photosynthesis is a great source of nutrients for photosynthetic organisms and plants.

Therefore, photosynthesis in plants is an example of nutrition

Answer:

The correct answer is - small intestine; glucagon, glycogen; glycerol, sodium bicarbonate; starch, iron, plasma, hemoglobin; fats.

Explanation:

The digestive enzymes are released in the small intestine by pancreatic cell, the cluster of these pancreatic exocrine cells called pancreatic islets that release insulin and glucagon hormones for controlling blood sugar level.

Insulin stores the excess amount of blood glucose in the liver as glycogen and in the case of low sugar glycerol is converted to glucose from fats. Pancreatic juice contains sodium bicarbonate to regulate acidity and the amylase enzyme helps in digesting starch. The liver stores various nutritional substances such as vitamins and iron and others and release them in blood plasma.
