Agricultural products travel an average of 1400 miles from farm to plate in the United States.

What are the largest particles formed from the breakdown of rock?

Gravel particles are the largest particles formed from the breakdown of rock.

How do prokaryotes contribute to plant health select all that apply?

How do prokaryotes contribute to plant health? Prokaryotes fix atmospheric nitrogen Prokaryotes secrete chemicals that stimulate plant growth and protect plant roots from disease.

What group of plants provides most of our food?

Most of our food crops come from angiosperms.

How long does it take to form 1 inch of soil?

An often asked question is “How long does it take to form an inch of topsoil?” This question has many different answers but most soil scientists agree that it takes at least 100 years and it varies depending on climate vegetation and other factors.

How rocks break down into soil?

Under the action of heat cold rain wind and other atmospheric factors the rock breaks down physically into small fragments that become the parent material of the soil. The rock also chemically changes as the compounds in the rock dissolve in rain or react with air.

What does the capsule do in a prokaryotic cell?

Many prokaryotes have a sticky outermost layer called the capsule which is usually made of polysaccharides (sugar polymers). The capsule helps prokaryotes cling to each other and to various surfaces in their environment and also helps prevent the cell from drying out.

Do all prokaryotes have endospores?

Not all bacteria have the ability to form endospores however there are a number of clinically significant endospore-forming gram-positive bacteria of the genera Bacillus and Clostridium. These include B. anthracis the causative agent of anthrax which produces endospores capable of survive for many decades C.

Which of the following domains contain prokaryotes that are known for living in extreme environments?

The domains Bacteria and Archaea are the ones containing prokaryotic organisms. The Archaea are prokaryotes that inhabit extreme environments such as inside of volcanoes while Bacteria are more common organisms such as E. coli.

What are gymnosperms closely related to?

The branching pattern of the phylogenetic tree in the activity indicates that angiosperms are most closely related to gymnosperms.

What is the conspicuous part of a fern plant?

leaf

The most conspicuous part of the fern sporophyte is the leaf.

How many gymnosperms are there?

1000 species
There are around 1000 species of gymnosperm. You can also browse genera found in Gymnosperms.

Where do humans fall on the food chain?

Humans are said to be at the top of the food chain because they eat plants and animals of all kinds but are not eaten consistently by any animals. The human food chain starts with plants. Plants eaten by humans are called fruits and vegetables and when they eat these plants humans are primary consumers.

How plants manufacture their own food?

Photosynthesis. Plants are autotrophs which means they produce their own food. They use the process of photosynthesis to transform water sunlight and carbon dioxide into oxygen and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

What are those called who get their own food by directly eating plants?

An autotroph is an organism that can produce its own food using light water carbon dioxide or other chemicals. Because autotrophs produce their own food they are sometimes called producers.

Which farming causes minimum disturbance to soil?

Explanation: No-till farming No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through tillage.

Why does it take thousands of years for soil to form?

1) How long does it take an inch of soil to form? It may take hundreds to thousands of years. It will take longer in colder and drier regions than in warmer and wetter regions. This is due to the soil forming processes such as translocation and transformation being slower in cold and/or dry areas.

How long does it take to build enough soil to farm effectively?

The time needed to form a soil depends on the latitude: in environments characterized by a mild climate it takes 200-400 years to form 1 cm of soil. in wet tropical areas soil formation is faster as it takes 200 years. in order to accumulate enough substances to make a soil fertile it takes 3000 years.

What is in the subsoil?

The subsoil may contain some broken down organic matter but it is mostly made of weathered rocks and clay minerals. Plants send their roots into both of these layers to find water stored in the soil and to find nutrients that they need to grow and to use for photosynthesis.

How would you create a very thin sandy soil?

To improve sandy soil:

Work in 3 to 4 inches of organic matter such as well-rotted manure or finished compost.
Mulch around your plants with leaves wood chips bark hay or straw. Mulch retains moisture and cools the soil.
Add at least 2 inches of organic matter each year.
Grow cover crops or green manures.

What happens to sediment after a million years?

Over millions of years layers of sediment may build up and harden into sedimentary rock. Some of the many forms of sedimentary rock include sandstone rock salt and coal. Sandstone forms as sand hardens.

Where are capsules in a cell?

3.2 Capsules. The bacterial capsule is usually a hydrated polysaccharide structure that covers the outer layer of the cell wall and in most bacteria it is composed of monosaccharides linked together via glycosidic bonds.

How does a prokaryotic cell move?

Prokaryotic cells move through liquids or over moist surfaces by swimming swarming gliding twitching or floating. An impressive diversity of motility mechanisms has evolved in prokaryotes. Movement can involve surface appendages such as flagella that spin pili that pull and Mycoplasma ‘legs’ that walk.

How many structures do prokaryotic cells have?

There are four main structures shared by all prokaryotic cells bacterial or archaean: The plasma membrane. Cytoplasm. Ribosomes.

What is Glycocalyx made up of?

The glycocalyx which is located on the apical surface of endothelial cells is composed of a negatively charged network of proteoglycans glycoproteins and glycolipids.

What is the stimulus for chemotaxis?

Chemotaxis is the directed migration of a cell in response to a chemical stimulus such as a growth factor. The specific ligands and receptors used in chemotaxis vary among cell types as do the specific mechanisms used to relay chemotactic signals.

Do bacteria use phagocytosis?

Bacteria dead tissue cells and small mineral particles are all examples of objects that may be phagocytized. Some protozoa use phagocytosis as means to obtain nutrients.

How long have eukaryotes been on Earth?

The eukaryotes developed at least 2.7 billion years ago following some 1 to 1.5 billion years of prokaryotic evolution. Studies of their DNA sequences indicate that the archaebacteria and eubacteria are as different from each other as either is from present-day eukaryotes.

How common are prokaryotes on Earth?

The number of prokaryotes in a single handful is 10 times as many as the number of people who have ever lived. They thrive where other organisms are not able to.

Which of the following domain contains the most primitive prokaryotes that live in extreme environment?

Archaea is the domain which contains the most primitive bacteria that live in extreme environments. Some of the first archaea were found in Yellowstone National Park’s hot springs.

Do gymnosperms pollinate?

In gymnosperms pollination involves pollen transfer from the male cone to the female cone. Upon transfer the pollen germinates to form the pollen tube and the sperm for fertilizing the egg. Pollination has been well studied since the time of Gregor Mendel.

What produces moss sperm?

At regular intervals depending on species and weather condition mosses produce small sexual structures known as archegonium (female structure that produces egg cells) or antheridium (male structure that produces sperm cells).

What is the most recognizable gymnosperm?

Gymnosperms are vascular plants of the subkingdom Embyophyta and include conifers cycads ginkgoes and gnetophytes. Some of the most recognizable examples of these woody shrubs and trees include pines spruces firs and ginkgoes.
