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.
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.

These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.

Final answer:
Homeostasis maintains a stable internal environment in organisms through feedback mechanisms. An example of a feedback mechanism is the regulation of blood glucose levels. If homeostasis fails, diseases such as diabetes may emerge.
Explanation:
Homeostasis is the process where an organism maintains a stable internal environment, which is crucial for survival. This stability is achieved through feedback mechanisms. These mechanisms monitor and adjust various biological systems within the body to maintain balance.
One example of a feedback mechanism in the human body is the regulation of blood glucose levels. When blood glucose levels rise, the pancreas produces insulin, which promotes the uptake of glucose into cells, reducing blood glucose levels. This is an example of a negative feedback mechanism because the effect of the response to the stimulus is to reduce the original stimulus. Conversely, if blood glucose levels fall, the pancreas produces glucagon, which prompts the liver to release stored glucose, thus increasing blood glucose levels.
If homeostasis fails in the human body, one specific result, beside death, could be the emergence of diseases such as diabetes. If the feedback mechanism for regulating blood glucose levels is impaired and the body doesn't produce enough insulin or the body's cells resist the effects of insulin, the result is high blood sugar and diabetic conditions.

People with Ectopmorph body type has larger brains.
Answer:
FALSE
Explanation:
Endomorph: It is the biotype with lower metabolism rate, which causes greater tendency to accumulate body fat. Greater difficulty in achieving toning, making the muscles more flabby. But that does not alter the size of the brain of the individual.
Traditionally, people with this biotype have greater difficulty in maintaining body weight, with a controlled diet, as well as physical exercise, aiming to reduce or maintain body weight.

Plants absorb carbon dioxide during photosynthesis, reducing atmospheric carbon levels, playing a crucial role in regulating the Earth's carbon balance.
The impact of plants on atmospheric carbon levels is twofold. First, they act as carbon sinks by storing carbon within their tissues.
This stored carbon can include not only the carbohydrates produced during photosynthesis but also carbon within the plant's structure and roots. Over time, this stored carbon can accumulate, helping to reduce the concentration of CO2 in the atmosphere.
Second, plants release oxygen into the atmosphere during photosynthesis, which is crucial for the respiration of many organisms, including humans.
This exchange of CO2 for O2 in the atmosphere is a vital part of the carbon cycle, which influences the Earth's climate.
Furthermore, when plants die and decompose or are consumed by herbivores, some of the stored carbon is released back into the atmosphere as CO2 through processes like respiration and decomposition.
However, a portion of the carbon can also be stored in the soil, contributing to long-term carbon sequestration.
plants on Earth help regulate the amount of carbon in the atmosphere by acting as carbon sinks during photosynthesis and releasing oxygen. Their role in the carbon cycle is crucial for maintaining the Earth's climate and ecosystem balance.
