You are viewing an organ of the respiratory system and note the following tissues: folded mucosal layer containing simple cuboidal epithelium and smooth muscle, shifting into simple squamous epithelia. Identify the organ.
Answer:
Respiratory bronchiole
Explanation:
The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.

What is an endoscope?An endoscope is a medical instrument that consists of a long, thin, flexible tube equipped with a light source and a camera at the tip. It is used by doctors to visualize and examine internal organs or structures within the body. The endoscope can be inserted through natural body openings like the mouth, anus, or small incisions to access various areas of the body.
It allows for direct visualization of the internal organs, capturing real-time images or videos that can be viewed on a monitor. Endoscopes are commonly used for diagnostic purposes, such as examining the gastrointestinal tract, respiratory system, urinary tract, or joints. They can also be used for therapeutic procedures, such as removing polyps, taking biopsies, or performing minimally invasive surgeries.
Endoscopes have revolutionized medical diagnostics and interventions by providing a less invasive alternative to traditional surgical methods.

What is the plant leaves function?Leaves are the primary site for photosynthesis, the process by which plants use sunlight, water, and carbon dioxide to produce food (glucose) and oxygen. Leaves also play a crucial role in gas exchange, allowing plants to take in carbon dioxide and release oxygen during photosynthesis and release carbon dioxide and take in oxygen during respiration. Leaves are responsible for transpiration, the process by which water is absorbed by the roots and transported through the plant to the leaves, where it is released into the air through tiny openings called stomata.
Hence, the main function of the structure identified as A in the picture is to synthesize the foods of the plants, which is the second option.

Which statement best explains why cellular respiration in plants and other organisms is dependent on photosynthesis?
Answer:
Cellular respiration depends on two chemical reactants; glucose and oxygen. Glucose and oxygen are made available to plants and animals for cellular respiration thanks to photosynthesis. Photosynthesis is the chemical reaction that uses solar energy to convert water and carbon dioxide into glucose and oxygen. Without photosynthesis, the available glucose and oxygen on the planet would quickly deplete to the point that life could not be sustained on Earth. So the answer would be B :).
Explanation: Hope this helps and good luck :)!
Answer:
Since photosynthesis is the process whereby plant manufacture its own food using a sunlight, so respiration can happen because plant is alive

Mendel used more than 28,000 pea plants in his experiments. Why is it important that he studied such a large sample of pea plants?
A. The pea plants were very inexpensive.
B. Most pea plants die after producing seeds.
C. Having more samples gave him results that were closer to the predicted ratios.
D. Using more plants made the experiments take less time.
Having more samples gave him results that were closer to the predicted ratios.Mendel's experiments involved studying the inheritance of traits in pea plants. By carefully crossing different varieties of pea plants and observing the traits of their offspring, he was able to formulate the laws of inheritance that are still used today.
What does Mendel's experiments involves?Mendel's experiments involved observing the inheritance of traits in pea plants, which were controlled by genes.
By studying a large sample size of 28,000 pea plants, he was able to obtain data that was much more reliable and accurate. This is because the larger the sample size, the closer the results will be to the expected outcomes or predicted ratios, and any anomalies or errors would be minimized.
This is an important principle in statistics and scientific research, and it helps to ensure the validity and generalizability of the findings.
Additionally, by using such a large number of plants, Mendel was able to minimize the impact of any outliers or anomalous results that might have occurred in a smaller sample. This helped to ensure that his results were as accurate and reliable as possible.

Leaf is modified into thorn where water availability is low.....give reason?
Answer:
To help conserve water or prevent loss via transpiration from the leaves
Explanation:
Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.
One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.

Sometimes individuals at one extreme of a phenotypic distribution are favored in a particular environment, for example, selection will strongly favor insects that have very high resistance to an insecticide. In such cases, the type of selection that operates is
Answer:
directional
Explanation:
We define directional selection as a type of natural selection whereby a phenotype is favored in preference to other phenotypes hence, the entire allele in the population will tend to shift in that particular direction .
This is clearly demonstrated in a scenario whereby insects that have very high resistance to an insecticide tend to survive better in an environment compared to other insects that do not exhibit this phenotype.

Mycoplasmas which belong to Firmicutes are pleomorphic because: (2 pts) they have no cell walls they are low G C content Gram-positive bacteria they exhibit snapping division they reproduce asexually they produce endospores
Answer:
they have no cell walls.
Explanation:
Mycoplasmas that belong to Firmicutes are considered as pleomorphic because they have no cell walls in their structure. Mycoplasmas have the following characteristics i.e. the smallest mycoplasmas are 125–250 nm in size, they are highly pleomorphic because they lack a rigid cell wall and instead of cell wall they are bounded by a triple-layered “unit membrane” that contains a sterol in its structure.
a permanent disease process that is characterized by destruction of the alveolar walls and distention of the alveolar sacs is a type of COPD called
Answer:
Emphysema
Explanation:
Pulmonary emphysema disease progressively destroys the fibers that promote respiration, leading to a decrease in respiratory function, emphysema being a more serious complication of any bronchopulmonary obstructive inflammation. In emphysema, the walls that separate many of the alveoli are damaged and gas exchange in the lungs decreases. This disease originates when the pulmonary alveoli are progressively destroyed and difficulty in breathing becomes greater and greater. When destroyed, a larger space is created, instead of small chambers. And this affects the length of the lungs and the amount of oxygen that reaches the blood.
