Answer:
Neurons, or nerve cells, are primarily located throughout the human body, but their highest concentration is within the nervous system, which includes the brain and spinal cord. So, the correct answer is not listed among the options, but neurons are mainly found within the nervous system.
The answer is B. Disruptive selection
The correct answer is Mitosis.
The mitosis is a type of cell division, in which the parent cell produces a similar type of daughter cell. The daughter cells, which are formed by the process of the mitosis would have the same number of the chromosomes and the ploidy of the daughter cells would also be same as the parents. In the sexual reproduction, the process of meiosis result in the formation of haploid cells during the process of gamete formation. Hence, meiosis, sexual reproduction, and gamete formation are incorrect answers.
Answer:
Key Differences Between Light Microscope and Electron Microscope.
How I got it:
Following are the main differences between Light Microscope and Electron Microscope: Light Microscope uses visible light, and Electron Microscope uses electrons (beam of charged particles) to view the object.
b. from the cell to the air.
c. from the water to the cell.
d. from the nucleus to the mitochondria.
The completed question is,
Identify the biotic factor of an ecosystem from the following:
a. soil composition
b. trees
c. temperature
d. sunlight
Option b. trees are the biotic factor of an ecosystem.
An ecosystem includes all the organisms and the physical environment with which they interact. These biotic and abiotic components exist linked together through nutrient cycles and energy flows. The energy penetrates the system through photosynthesis and exists incorporated into plant tissue.
The primary types of ecosystems are forests, grasslands, deserts, tundra, freshwater, and marine. The word “biome” may even be used to represent terrestrial ecosystems that extend across a large geographic area, such as the tundra.
With the provided choices. it exists trees that are categorized as biotic factors of an ecosystem. Biotic factor guides living things found in the ecosystem. Trees exist as living things that furnish oxygen for humans and animals to live.
Hence, Option b. trees are the biotic factor of an ecosystem.
