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.

Answer:
Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus. Mitosis is conventionally divided into five stages known as prophase, prometaphase, metaphase, anaphase, and telophase. While mitosis is taking place, there is no cell growth and all of the cellular energy is focused on cell division.

THIS ONE conducting impulses.
absorbing vital nutrients.
Answer:
- Nervous tissue is made up of neuroglia and neurons.
- Nervous tissue transmits messages throughout the human body by conducting impulses.
Explanation:
The nervous system is in charge of the control of all organic functions, so it has the central and peripheral nervous systems. This system is made up of a highly specialized tissue, the nervous tissue.
The nervous tissue is composed of neurons —the functional unit— and the neuroglia, a tissue that provides support and nutritional supply. The neuron has a body or soma, and extensions called axons and dendrites. These neuronal prolongations are those that allow the transmission of information by means of electrical signals, also called conducting impulses.
About the options for each approach:
1. Nerve tissue and its components
Sarcomero is the muscle fiber, the functional unit of the muscles. Ovules are female sex cells. Stem cells are undifferentiated cells with the ability to form specialized cells.2. Nervous tissue transmits messages

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.

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.

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.
