I. Plant cells are formed from fertile soil. II. Animal cells must function properly for an organism to be healthy. III.Cells make up the petals, stem, and leaves of a lily plant. IV. Bacteria are produced from other living bacteria. Which describes the statements that Schwann and Schleiden would make? Schwann would make Statement I and Schleiden would make Statement IV. Schwann would make Statement II and Schleiden would make Statement III. Schwann would make Statement III and Schleiden would make Statement II. Schwann would make Statement IV and Schleiden would make Statement I.

Answers

Answer:

Schwann would make statement II and Schleiden would make statement III

Explanation:

Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.

As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.

Answer:

B- Schwann would make Statement II and Schleiden would make Statement III.

Why is mass a better unit for measuring matter than weight?*
Because mass can change, but weight doesn't
Because mass is constant, while weight depends on gravity.
Because it makes more sense.

Answers

Answer:

Because mass is constant, while weight depends on gravity.

Explanation:

For example, your mass on Earth will be the same as your mass on planet Mars. Your weight however, will change depending on the force of gravity exerted on you.

- Chromosomes are made of DNA that contain genes that control the production of ______ within the cell.

Answers

Answer: Proteins

Explanation: genes contain info that tell your cells to make molecules called proteins

Chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

What is the significance of DNA as a blueprint?

The DNA acts as a blueprint in which all of the cell's information is stored, such as in the form of a gene, which is later expressed in the cell in the form of polypeptides, proteins, enzymes, and so on by the translation process, and controls and regulates the cell for various functions. DNA contains lots of genes, but not all of them are expressible.

Hence, chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

Answer:

A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0. Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H+ions or OH– ions, thereby maintaining an overall steady pH in the solution.

What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?​

Answers

Answer:

Many reasons - but a really good question.

Explanation:

Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.

Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.

Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.

When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.

Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.

If you took a 20-foot tree and hammered a spike into it 3-feet above the ground, how high would that spike be 30 years later when the tree is 100 feet tall? and why?

Answers

Answer:

The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.

Please find the explanation below

Explanation:

Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.

This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.

Why are the Kreb's cycle and ETC
considered aerobic processes?

Answers

Answer:

Without oxygen, the electron transport chain becomes jammed with electrons. Consequently, NAD cannot be produced, thereby causing glycolysis to produce lactic acid instead of pyruvate, which is a necessary component of the Krebs Cycle. Thus, the Krebs cycle is heavily dependent on oxygen, deeming it an aerobic process.

what happens to a enzyme after it has completed a reaction?

Answers

Answer: The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).

Enzymes are not consumed in the reaction, they can continue catalyzing more reactions, they can remain bound to the product or they can be degraded.

What are enzymes?

Enzymes are biomolecules that catalyze chemical reactions in living organisms. They are typically proteins, although RNA molecules known as ribozymes also exist. Enzymes are responsible for many of the metabolic processes that occur in cells and are essential for life. They are highly specific, meaning that they typically only catalyze one or a few specific reactions, and they increase the rate of reactions by reducing the activation energy required for the reaction to occur.

After an enzyme has completed a reaction, it is still present and can continue to catalyze more reactions. Enzymes can catalyze thousands of reactions per second, and they can remain active for long periods of time. However, enzymes can also be inactivated or destroyed by various factors, such as high temperatures, changes in pH, or the presence of certain chemicals

What macromolecules can be found in animal cells

and

What macromolecules can be found in plant cells

Answers

Answer:

ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.

PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.

The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.

What are Macromolecules?

Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.

The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.

All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.
