Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.

Your answer: Here are 3 reasons that go against growing wheat this way.

1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.

2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.

3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.

If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

When and where would you expect to find the highest rate of primary productivity

Answers

Answer: Net primary productivity is the amount of gross primary productivity remaining after respiration, which is about 40 and 85 percent. Sloughs and marshes, as well as tropical rain forests, possess the highest rates of net primary productivity; deserts have the lowest.

Explanation:

I explained on the top-

The highest rate of primary productivity in terrestrial environments takes place in swamps and marshes and in tropical rainforests, and in aquatic environments it takes place in algal beds, estuaries, and reefs.  

• In ecology, primary productivity refers to the rate at which conversion of energy to organic substances takes place by the photosynthetic producers that attain energy and nutrients from the sunlight, and chemosynthetic producers that attain chemical energy via oxidation.  

• The majority of the energy assimilated by plants via the process of photosynthesis is not stored as organic substance, however, is utilized at the time of cellular respiration.  

• In the process, the organic components like proteins, carbs, and fats are dissociated to provide energy in the form of ATP for the metabolic needs of the cells.  

• The energy not utilized is stored in the tissues of the plants for future use and is known as the net primary productivity.  

• The highest net primary productivity in terrestrial environments takes place in marshes and swamps and in tropical rainforests, and in aquatic environments it takes place algal beds, estuaries, and reefs.  

These environments are mainly critical for the sustenance of global biological productivity.

Starch is a polysaccharide used as a component of cell walls in plants.


True

False

Answers

Answer:

false

Explanation:

is type of carbohydrates

False. Starch is a polysaccharide used as an energy storage molecule in plants, but it is not a component of cell walls.

What are structural component of cell wall?

Cell walls are structural components found in the outermost layers of cells in plants, fungi, and some bacteria. They provide support and protection for the cell, and are composed of a variety of different biomolecules, including cellulose, pectin, and lignin.

Starch, on the other hand, is a complex carbohydrate that is synthesized and stored in the cells of plants, particularly in the seeds, roots, and tubers. It is made up of long chains of glucose molecules and is used by plants as an energy source, particularly during times when the plant does not have access to light for photosynthesis. Starch is not a component of cell walls.

which feature of stem cells enable them to replace cells in tissues such as skin?

Answers

That is right!!!!! Hope that helped

The feature of stem cell which enable them to replace cell in tissues are that they can divide indefinitely to generate new cells and they can convert into the different types of cells that make up the body as they divide.

What is a stem cell ?

A stem cell is a cell that has the unique capacity to grow into different types of cells in the body.

They may be utilised in the future to replace cells and tissues that have been damaged or destroyed owing to illness.

Stem cells are classified into three types which are Embryonic stem cells, Adult stem cells, Induced pluripotent stem cells.

Embryonic stem cells provide new cells to an embryo as it grows and develops into a newborn.

Adult stem cells generate new cells as an organism matures and replace damaged ones.

Induced stem cells are stem cells created in the laboratory by scientists.

Adrenergic receptors Select one: a. can be activated by the release of epinephrine. b. have two structural forms - muscarinic and nicotinic. c. when activated stimulate skeletal muscles to contract. d. can be found in both the sympathetic and parasympathetic divisions. e. are activated by the release of acetylcholine.

Answers

Answer:

The correct answer is  a. can be activated by the release of epinephrine.

Explanation:

Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.
