Explanation:

Explain how dysfunction at one level of organization impacts other levels and provide an example.

Answers

Answer:

Please find the explanation below

Explanation:

All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.

Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).

O A. The cuticle minimized water loss from leaves.
B. The cuticle absorbed nutrients from the soil.
C. The cuticle increased photosynthesis.
O D. The cuticle protected reproductive structures.
SUBMIT

Answers

Answer:

a

Explanation:

The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.

What is transpiration?

Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.

The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.

To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.

Thus, the correct option is A.

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:

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.

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!

Answers

Answer:

Explanation:

Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.

This is kind of a baseline descripiton but i hope it helps!

Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.

What  is the way to the food chain ?

For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.

Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.

Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.

Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.

which statement correctly describes the relationship between genes, proteins, and traits?

Answers

Answer:

C. Genes are transcribed into mRNA, the mRNA is then translated into proteins, which determines specific traits.

Explanation:

Genes are segments of the genetic material (DNA) that encodes certain products, which are heritable. In the central dogma of biology, genes are expressed via two processes viz: transcription and translation.

Transcription is the process whereby the information in genes are used to synthesize mRNA molecule, while Translation is the process whereby the mRNA molecule is used to synthesize proteins in the ribosome.

The proteins are responsible for the individual characteristics or traits possessed by living organisms. For example, MELANIN GENE is transcribed into MELANIN mRNA, which is then translated into MELANIN PROTEIN responsible for the skin colour (trait).

Multicellular fungi share some key traits, including their body structures, growth patterns, and methods for absorbing nutrients. however, although their feeding methods may be similar, fungal species differ markedly in their sources of nutrients, which include both living and dead organisms. as a result, fungi play a variety of roles in ecological communities.

Answers

Explanation:

The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.

They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.

And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.
