0r
-There isn’t enough energy available to support more secondary consumers.

Answers

Answer 1

Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.

When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.

Biomass change from lower to higher trophic levels by decreasing.

The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.

There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.

It should be noted that global warming brings about the increase in the temperature around the world.

what are the similarities and differences between carrier proteins and channel proteins​

Answers

* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.

* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.

Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.

A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules

The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.

What is a plague?

A plague is a highly infectious and often fatal disease caused by the bacterium Yersinia pestis. The most infamous outbreak of the plague occurred in the 14th century in Europe, killing an estimated 25 million people, or one-third of the population. The disease is typically spread through the bite of an infected flea, although it can also be transmitted through contact with infected animals or humans.

There are three forms of the plague: bubonic, septicemic, and pneumonic. Bubonic plague is the most common form and causes swollen lymph nodes, fever, chills, and fatigue. Septicemic plague affects the bloodstream and can cause fever, chills, abdominal pain, and vomiting. Pneumonic plague affects the lungs and can cause fever, cough, chest pain, and difficulty breathing.

Today, the plague is rare but still exists in some parts of the world, including Africa and Asia. Early diagnosis and treatment with antibiotics are essential for successful treatment of the disease.

At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)

Answers

Answer:

Genes are translated, transcribed and after these two steps, the formation of a protein takes place.

DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.

Proteins can be structural or functional.

Explanation:

There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.

Answers

Answer:

The correct answer is c.pinocytosis – liquids secreted from the cell

Explanation:

Pinocytosis is a type of endocytosis in which substances are internalized into the cell from the celullar exterior. The components are not secreted from the cell but are uptaken into the cell. This internalization process is characterized by the formation of an invagination of the cell membrane where then is formed a vesicle surrounding the component to be uptaken.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables

Answers

Answer:

Please find the explanation of independent and dependent variables below using the experiment in this question.

Explanation:

Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.

According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.

In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.
