The statement is false that in pneumothorax there is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline.
Pneumothorax is the condition where the lung collapses. All the air present inside the lungs is pushed out. There occurs a tracheal shift to the opposite side during the lung collapse, but the lung is not moved away from the midline.
Lungs are the main respiratory organ of the body. They are involved in the exchange of air from the blood. The lungs comprise of several very small air sacs called alveoli. These alveoli increase the surface area of the lung and hence increase the ventilation.

What would happen if you did an experiment in which the iodine solution was placed in a baggie, and the starch solution was in the beaker?
If the iodine solution was placed in a baggie and the starch solution was in the beaker, and the baggie was then submerged in the beaker, a specific chemical reaction called the iodine-starch reaction would occur.
The iodine-starch reaction is a well-known test used to detect the presence of starch in a solution. Normally, when iodine solution (iodine dissolved in water) comes into contact with starch, it forms a dark blue or black color complex.
This reaction is due to the formation of an inclusion complex between the iodine molecules and the helical structure of starch.

The brain coordinates the __________ to a stimulus. What word completes this sentence?
Different kinds of receptors in the skin and organs are capable of recognizing both internal and exterior inputs. Neurons in the sensory system send this data to the brain.
What are the Sensory system?Assembling sensory neurons create sensory nerves, which pass through the spinal cord to the brain.
The brain and spinal cord make up a person's central nervous system (CNS). When a receptor is activated, a signal travels through the neurons, or nerve cells, to the brain.
The effector receives nerve impulses from the brain, which the brain then uses to coordinate the reaction.
A sensory system is made up of neural networks, sensory neurons (including sensory receptor cells), and brain regions involved in sensory perception.
Therefore, brain coordinates the sensory responses to a stimulus.

Mitosis, a stage in the cell cycle, is important for what reason?
a. division of the nucleus b. removal of cancer cells
c. synthesis of DNA d. division of cytoplasm
Answer:
A. division of the nucleus
Explanation:
Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.
So, we are looking for an answer choice that involves division: either A or D.
At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.
Thus, the answer is A.

What is an algae?Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

In an aerobic cell, active transport is most directly affected by damage to
the
Mitochondria
chloroplasts
Ribosomes
centrioles
Answer:
mitochondria
Explanation:
aerobic is active and energy is produced in the mitochondria so if the mitochondria was damaged it would affect the active transport
In an aerobic cell, active transport is most directly affected by damage to the - Mitochondria as it provides energy for active movement.
Active transport is a movement of particles through the cell membrane against the gradient, or particles too large to move, therefore, they require additional energy to move such substances.
Cellular respiration provides energy for active transport.It takes place in the mitochondria, therefore, cells that perform active transport have many mitochondria.the molecules are moving against their concentration gradient.If mitochondria are damage in a cell there will be no energy formation and as active transport requires energy this process will be affected directly.
Thus, the correct answer is - mitochondria.

irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation
The discussion of irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation is given in the below paragraph-
The predominant migratory DC population in the small intestinal lamina propria (SI-LP) is composed of CD103(+)CD11b(+) dendritic cells (DCs), although it is yet unknown what these cells do in vivo. Here, we show that intestine CD103(+)CD11b(+) DC survival required IRF4 to function (IRF4). Mice with a DC loss in Irf4 showed decreased numbers of helper T 17 (Th17) cells that secrete IL-17 in the gastrointestinal tract and failed to support Th17 cell development in draining mesenteric lymph nodes (MLN) after immunization. Both CD103(+)CD11b(+) MLN DCs and DC-derived IL-6 were selectively decreased in the latter. Immunized Il6(-/-) mice were unable to sustain Th17 cell development in MLN in vivo, although CD103(+)CD11b(+) MLN DCs were able to do so in vitro.
Findings collectively point to a critical function for IRF4-dependent, IL-6-producing CD103(+)CD11b(+) DCs in intestinal Th17 cell development.
What is cell differentiation?The transformation of a stem cell from one type to a differentiated one is known as cellular differentiation. Usually, the cell transforms into a more focused kind. Multiple instances of differentiation take place while a multicellular creature develops from a straightforward zygote to a complex system of tissues and cell types.
As adult stem cells divide and produce completely differentiated daughter cells during tissue repair and normal cell turnover, differentiation continues throughout maturity. In response to antigen exposure, some differentiation takes place. Size, shape, membrane potential, metabolic activity, and signal responsiveness of a cell all undergo significant changes during differentiation.

c. if you begin with one tube of e. coli, how many different types of bacteria do you expect to see in the 4th quadrant?
If we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.
To observe the colonies of a bacteria in form of quadrants, we need to follow the below-mentioned steps:
To culture bacteria, we need to transfer it to a petri dish.A petri dish is coated with a layer of agar, a jelly-like substance obtained from red algae that helps in culturing bacteria.Then the required bacteria, which is E. coli in our case is collected using a sterile rod and put on the petri dish.After that, the petri dish is heated to increase the growth of bacteria and also to ensure equitable distribution of bacteria in all four quadrants.After following the above-mentioned steps we have to cover the petri dish to avoid contamination and leave it undisturbed for a few days.When we observe the dish after a few days, we will see the bacterial colonies growing in it, as shown in the adjoining image.Thus, if we begin with one tube of E. coli, we will only see one type of bacteria in the 4th quadrant, if any type of contamination does not occur.
