Cells assume different structures primarily on the basis of the function with which they are associated. Thus, the correct option is B.
The number of mitochondria or the size of the cell do not have any influence on the structure of the cell.
On the basis of the function, there are different features that are added or modified in the cell.
For instance, the cells in the intestine are primarily involved in absorption and hence, they have a special structure called villi on their apical surface for maximal absorption.
Similarly, RBCs have a disc shape for maximum surface area for fulfilling its function of oxygen absorption and diffusion.

Plants sustain continual growth in length by repeated cell division within these types of regions . A. Antheridia B. Archigonia C. Sepals D. Meristems E. Leave
Answer:
D. Meristems
Explanation:
Like every other living thing, plants also undergo growth in size (length and width). This growth in length is a characteristics of the cellular division that occurs in a region called MERISTEMS. Meristems are those part of a plants that contain tissues whose cells are always young and actively involved in cell division.
The cells in the MERISTEMS called TOTIPOTENT, which are found at the top or apices of root, shoot etc are involved in continual division, hence, the regions they are found visibly undergoes changes in length as cells multiplies in that region.

complete the flow of deoxygenated blood other parts of the body (a)_____(b)_____tricuspid valve (c)______(d)_______capillary bed of the lungs(alveoli)
Answer:
The correct flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)
Explanation:
Deoxygenated blood is moved from the tissues to the venules, veins or vena cava to the right atrium chamber and move through the tricuspid valve present in between both right chambers right atrium and right ventricle.
From the right ventricle, the deoxygenated blood is pumped into the pulmonary artery that takes the blood to the lungs more specifically to the capillary bed of lungs.
Thus, the flow is - the body (a) Venules/vein/vena cava (b) Right atrium tricuspid valve (c) Right ventricle (d) Pulmonary artery, capillary bed of the lungs(alveoli)

According to the Endosymbiotic Theory, the statement that represents the best explanation for what is happening in step C is as follows:
A cell engulfs an aerobic bacterial cell, without digesting it, allowing it to become an endosymbiont, giving the cell a survival advantage.Thus, the correct option for this question is found to be D.
What is Endosymbiotic theory?An Endosymbiotic theory may be characterized as a type of theory that demonstrates the evolution of a eukaryotic cell from a prokaryotic cell through the mechanism of engulfment. It typically observes numerous cell organelles in eukaryotic cells as descendants of endosymbionts.
The theory of endosymbiosis is generally given by Lynn Margulis. This theory was terminated in two steps. One governs the process of evolution of mitochondria while the other represents the origination of chloroplasts.
When anaerobic predator cell engulfs α-proteobacteria and gives rise to mitochondria. When this mitochondrion cell then engulfs cyanobacteria, it eventually leads to the formation of the chloroplast.
Therefore, the correct option for this question is found to be D.

Kyle is holding a bag of 250 jelly beans. When Mark takes out two jelly beans, Kyle is not able to tell a difference.
This illustrates
O Weber's law
absolute threshold
sensory adaptation
signal detection theory
Answer:
Sensory adaptation.
Explanation:
Hello.
In this case, after the removal of the two jelly beans, Kyle has now 248 jelly beans which is a slightly neglectable difference, it means that the answer is sensory adaptation since it refers to a decrease in the sensitivity to a stimulus due to the constant exposure to it, which also reduces our awareness when a neglectable change happens.
This is proved since Kyle was constantly holding the bag so a difference of two jelly beans will be almost neglectable making the sensory adaptation the reason behind this.

Organic semiconductors are a new technology that scientists are considering for the next generation of solar
panels. Manufacturers want to produce efficient semiconductors at a low cost. Which type of organic
semiconductors would be most desired as a solar panel technology?
The specific properties of the most desired organic semiconductors for solar panel technology may evolve as advancements are made in the field.
In the context of solar panel technology, the most desired type of organic semiconductors would typically possess the following characteristics:
High Efficiency: The organic semiconductors should have a high power conversion efficiency, meaning they can efficiently convert sunlight into electricity. This is crucial for maximizing the electricity output of solar panels.
Tunable Bandgap: Organic semiconductors with a tunable bandgap would be advantageous. The bandgap determines the range of light wavelengths that can be absorbed by the material. A tunable bandgap allows for optimization to match the solar spectrum, enabling better absorption of sunlight and improved overall efficiency.
Long Operational Lifetime: The organic semiconductors should be stable and exhibit a long operational lifetime. Solar panels are expected to endure outdoor conditions for many years, so the materials used should be resistant to degradation, such as from exposure to UV radiation or moisture.
Scalability and Low Cost: Manufacturers aim to produce organic semiconductors on a large scale at a low cost. Therefore, desirable organic semiconductors should be readily synthesized using cost-effective methods and be compatible with high-volume manufacturing processes.
Environmental Friendliness: Organic semiconductors that are environmentally friendly and have low toxicity are desirable. This is aligned with the goal of sustainable and clean energy technologies.
It is important to note that the field of organic semiconductor research is still evolving, and scientists are continually working to improve the performance and characteristics of these materials.
