A wet mount of unstained Elodea ( a green aquatic plant) is observed using high power (400x) of a compound light microscope. Which structures would most likely be observed? ribosome, Golgi complex, and vacuole ribosome, Golgi complex, and vacuole nucleus, chloroplast, and cell wall nucleus, chloroplast, and cell wall centrosome, lysosome, and plasma membrane centrosome, lysosome, and plasma membrane cytoplasm, endoplasmic reticulum, and nucleolus

Answers

Answer 1

Answer:

The correct option is "nucleus, chloroplast, and cell wall"

Explanation:

The specimen described in the question is said to be green aquatic plant. Hence, the organelles expected to be viewed are those present in a pant cell.

Although, nucleus (stores the genetic material) is present in both plant and animal cells, however, chloroplast (to provide the green colour for the aquatic plant) and cell wall (for the cell's rigidity and support) are only found in a plant cells.

What happens to glucose which enters nephron along with filtrate

Answers

Answer:

it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion.

When glucose enters nephron along with filtrate, it goes down the renal tubule by the action of cilia. The tubular cells absorb glucose, amino acids, salts, etc. These are then passed into the capillary blood cells using the process of diffusion. Selective reabsorption is the process whereby certain molecules (e.g. ions, glucose and amino acids), after being filtered out of the capillaries along with nitrogenous waste products (i.e. urea) and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. Glucose that enters the nephron along with the filtrate after passing through the glomerulus, passes from the tubule of nephron where it is selectively reabsorbed and sent back to blood.
The filtered part of blood that is collected into the Bowman's space is called glomerular filtrate . ... Once the filtrate passes through the proximal convoluted tubule , the primary site of absorption, 100% of the glucose is reabsorbed back into the blood, including other nutrients and molecules. Nephric filtrate goes to Bowman's capsule when glucose comes out from it. The filtrate then passes through the tube where the blood capillaries absorb glucose. The capillaries of the blood carry glucose to all the cells of the body. Reabsorption. Reabsorption takes place mainly in the proximal convoluted tubule of the nephron . Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules. Following a meal, glucose utilization by the kidney increases. Normally each day, ∼180 g of glucose is filtered by the kidneys; almost all of this is reabsorbed by means of sodium–glucose co-transporter 2 (SGLT2), expressed in the proximal tubules.

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.

answer the following questions regarding the organism that the product is derived from (reasonable guesses or
speculation is ok):
1. What is the organism?
2. Where does the organism live?
3. Briefly characterize the ecosystem that the organism lives in.
4. Provide one example of how the organism depends on another organism.
5. What are some threats to the organism in the ecosystem?
Speculate on how your life would be affected if the organism became extinct.

Answers

Answer:

1. An organism is a individual animal, plant, or single-celled life form.

2. Habitat, place where an organism or a community of organisms lives, including all living and nonliving factors or conditions of the surrounding environment. Like a forest, lake, coral reef, desert, towns or cities.

3. An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors are animals, trees, plants, and abiotic factors are things that have never been alive. So rock rivers, ponds, man made objects.

4. When a organism depends on another is called symbiotic relationships. There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism. Mutualism: both partners benefit. An example of mutualism involves goby fish and shrimp. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone.

5. Pollution(water&air), deforestation, UV Radiation, invasive species.

If an organism went extinct the next generation won't ever be able to see those organisms. If an organism we eat went extinct we would have one less food source which is something that really does not need to happen in today world.

The plant lives in soil in an agricultural field.

The cotton plant requires bees for pollination.

The plant may be threatened by diseases such as cotton leaf curl disease, pests such as aphids, and drought.

If cotton became extinct, my pants would have to be made of some other material, such as linen or wool, which would feel quite different. This would be a big adjustment for me because I am used to wearing cotton pants almost every day.

what are the factors affecting photosynthesis ?

The process in which autotrophic plants use light energy from sun and convert it into chemical energy, and prepare their food in the form of glucose called as photosynthesis.

This chemical energy is created from water and carbon dioxide and stored as a sugar molecule, it occur in chloroplasts which has three pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.

various factors influence photosynthesis like increase in light intensity causes higher rate of photosynthesis, Higher concentration of carbon dioxide increases the rate of photosynthesis, Temperature range between 25° to 35° C optimum for photosynthesis,

Thus option B and D are correct.

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.

What do you mean by dissociation?

Dissociation is the process by which chemical molecules (or ionic compounds such as salts, or complexes) break down into simpler constituents such as atoms, ions or radicals, usually in a reversible manner.

Moreover, the dissociation of water is an equilibrium reaction in which one water molecule donates its proton to another water molecule.

Salts that are soluble in water dissociate into their ions and are electrolytes. Salts that are insoluble or only slightly soluble in water form very few ions in solution and are nonelectrolytes or weak electrolytes.
