Once amylase has broken down starch, can it break down another starch molecule?

Answers

Answer:

Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.

Explanation:

Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.

The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.

Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

Small insects can walk across the surface of calm water.
Their feet push the surface of the water down slightly,
somewhat like a person walking across a trampoline, but
they do not break the surface. What is the best
explanation for why this happens?

A. The insects are light enough so that they do not break the hydrogen bonds holding the water molecules

B. The insects actually use their wings to hover slightly above the waters surface and they only skim it with their feet

C. The insects feet are non- polar so they are repelled by the polar water molecules and are pushed away from the waters surface

D. The insects are small enough to see the individual water molecules so they are able to step carefully from one molecule to the next

A. Insects are light enough so that they do not break the h bonds holding the water molecules together

Explanation:

The insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.

What is surface tension?

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.

Surface tension is responsible for the shape of liquid droplets and the surface tension of water is about 72 mN/m at room temperature.

Water has a tremendous amount of surface tension due to which small mass distributed effectively on its surface.

Surface tension is represented by the symbol T.

Therefore,the insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.

Explanation:

Chloroplast absorbs sunlight also known as light energy used for the process of photosynthesis.

The observed specimen containing a cell wall, nucleus, and chloroplasts is most likely to belong to a plant cell.

PLANT CELL:

A plant is an organism whose cells contain organelles called chloroplast, which harbors chlorophyll pigment. This feature enables them perform photosynthesis; a process that plants use to synthesize their food.

Plant cells are eukaryotic in nature i.e. they contain a membrane-bound nucleus in their cells.

In addition to these organelles, plant cells also possess a cellulose-embedded cell wall that strengthens the cell.

The information that can be determined from the given formula is the number of atoms of each element in a glucose molecule. The correct option is D.

What is an element?

Any substance that cannot be decomposed into simpler substances by ordinary chemical processes is referred to as a chemical element. Elements are the fundamental building blocks of all matter.

An element is a pure substance that cannot be broken down into simpler substances through physical or chemical means.

An element is composed of the same type of atoms. Metals, nonmetals, and metalloids are the three types of elements. The symbols for the elements are used to represent them.

Glucose is made up of three elements: carbon, hydrogen, and oxygen. 6 carbon atoms bonded together in a chain with oxygen and hydrogen atoms.

Orchids are flowering plants that dependent visa punishment a pol a population of orchids in a rain forest has reached its carrying capacity rainforest be population is a limiting factor in the orca population what will happen to the orchids caring capacity of the rainforest

Answers

Answer:

Explanation:

The question is incomplete below is the correct version of the question.

Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases? A. The carrying capacity will not change because it is a constant property of a species. B. The carrying capacity will not change because it is a constant property of an ecosystem. C. The carrying capacity will decrease because the level of the limiting factor decreases. D. The carrying capacity will increase because the level of the limiting factor decreases.

Answer :C. The carrying capacity will decrease because the level of the limiting factor decreases.

Explanation:

The carrying capacity of a system is how much population an habitat can sustain depending on the available resources without leading to competition. This resources include food, water, space.

Since Rain forest bee is a limiting factor for orchid therefore Orchid population is dependent on the Rainforest bee's population so a decrease in the bee's population will lead to a decrease in the orchid population.

This will then lead us to a decrease in the carrying capacity of the system due reduction in the population of the limiting factor the bee because carrying capacity is population dependent.

Matthias Schleiden used a microscope to observe that the
parts of plants consist of cells. Theodor Schwann used a
microscope to observe that the parts of animals consist of
cells.
Which two statements did the work of Schleiden and Schwann add to the cell
theory?
A. All living things are made of one or more cells.
B. All cells come from other living cells.
C. Cells contain genetic material that consists of DNA.
D. The cell is the basic structural and functional unit of life.

Answers

Answer:

The work of Schleiden and Schwann provided to the Cell Theory the conclusions relating to that all living things are made of one or more cells and the cell is the basic structural and functional unit of life.

Explanation:

Matthias Schleiden was a German botanist who in 1937, while studying plant tissue under the microscope, observed that all plants are made up of cells.

In 1938, physiologist Theodor Schwann performed an experiment similar to Schleiden's, but using animal tissue, concluding that animals are made up of cells.

By bringing together the findings of both scientists, two important conclusions for Cell Theory were reached:

The cell is the structural and functional unit of all living beings. All living organisms are made up of one or more cells.

Both conclusions are part of the cellular theory, as it is known today.

Regarding other options:

    B. All cells come from other living cells was a conclusion provided by Rudolf Virchow.

    C. Cells contain genetic material that consists of DNA is an argument that is not part of the cellular theory. In fact, the DNA would not be discovered until 1953.
