Which best describes stem cells? Differentiation creates specialized cells from stem cells. Self-renewal creates stem cells from differentiated cells. Self-renewal creates differentiated cells from stem cells. Differentiation creates stem cells from specialized cells.
Answer:
Differentiation creates specialized cells from stem cells
Explanation:
Stem cells refers to the undifferentiated cells that are capable of repeated cell division. During each division in stem cell, at least one of the daughter cells usually remains a stem cell. The rest of the newly formed daughter cells differentiate as a specific cell type.
Example: Stem cells present in bone marrow of human give rise to red blood cells, white blood cells and platelets.
Stem cells are unique cells that can differentiate into specialized cells and have the ability to self-renew, maintaining the stem cell population. They occur in different stages of human life and types, offering potential treatment for various diseases and cell-based therapies.
Explanation:The best description of stem cells is the one that states differentiation creates specialized cells from stem cells. Stem cells are unique cells that can differentiate into specialized cell types and also self-renew to maintain the stem cell population. They exist in different types, including embryonic stem cells (pluripotent), adult stem cells (multipotent), and induced pluripotent stem cells (reprogrammed to function like embryonic stem cells). They are extensively used in research and potential therapeutic applications to replace damaged or destroyed cells or tissues.
Stem cells are distinct for their ability to divide and regenerate new stem cells instead of further specializing, a process known as self-renewal. This property enables stem cells to be a potential treatment for diseases such as diabetes, and heart disease and could be utilized in cell-based therapies.

maintain homeostasis
synthesize minerals
produce light energy
decompose organic matter
Answer:
The correct answer is "maintain homeostasis".
Explanation:
Homeostasis is a concept used in science to refer to the propensity to have a constant internal environment within an organism. The plants maintain its water homeostasis in the along the whole plant by the dotted opening in its leaves known as stomata. By allowing the exchange of gases through stomata, the plant regulate how much water is presented in the roots and in the plant's body, maintaining an internal environment within the whole organism.

Answer: Option C
Explanation:
Maya believes that inchworms are faster when compared with snails. To prove this hypothesis she performs experiment and while performing experiment she ignored the inchworms that moves slower than snails.
This is a biased condition because she ignored the inchworms that were slow.
If she would have been unbiased then she should have tested all the inchworms that were slow or fast from snails.
Hence, option C is the correct answer.
How do algae, cyanobacteria, and plants produce their own food?
Algae, cyanobacteria and plants are autotrophs. They produce their own food by the process of photosynthesis.
The only living things with the ability to carry out photosynthesis are plants, algae, and a kind of bacteria known as cyanobacteria. Photoautotrophs are organisms that produce their own nourishment using light.
The only biological mechanism that turns sunlight, which is energy from space, into chemical energy in the form of G3P is photosynthesis, from which sugars and other molecules can be created.
In the process of photosynthesis, light-absorbing molecules in leaves energize electrons, which are subsequently stored in the covalent bonds of carbohydrates. When those covalent connections are broken during cell respiration, the energy contained inside them is released.
Therefore, the algae, cyanobacteria and plants prepare their food by photosynthesis.

Final answer:
Algae, cyanobacteria, and plants, collectively referred to as photoautotrophs, use photosynthesis to convert sunlight, carbon dioxide, and water into glucose, providing the base for most food chains.
Explanation:
Algae, cyanobacteria, and plants produce their food through a process called photosynthesis. They are known as photoautotrophs, organisms that use sunlight as an energy source to synthesize organic compounds from carbon dioxide and water.
During photosynthesis, they capture light energy using pigments like chlorophyll, which is contained within organelles called chloroplasts in plants and algae, and within specialized structures in cyanobacteria. This energy is then used to convert carbon dioxide and water into glucose, a simple sugar, and to release oxygen as a byproduct. These organisms provide the base for most food chains and are essential for life on Earth because they produce the organic compounds that other organisms, known as heterotrophs, depend on for energy.
What is the common name of this gas, N2, the most prevalent in our atmosphere? A) sodium B) nickel C) nitrogen D) oxygen
Answer: The correct option is C) Nitrogen.
Nitrogen ( N₂) is the most prevalent gas in the atmosphere. It contributes 80% in the atmosphere. It is a highly stable gas because it contains three bonds between the two nitrogen atoms. So, it requires high energy to break these chemical bonds.
Nitrogen is the basic nutrient for the survival of all life forms. It is present in bio-molecules like proteins and DNA.
Nitrogen gas can not be used as such by the plants and animals. Therefore, it is converted into other forms so that plants and animals can utilize it. The process of conversion of N₂ into other biologically available form is termed as Nitrogen fixation.

What is the Sun's apparent path through the sky in the northern hemisphere
The Sun's apparent path through the sky in the northern hemisphere forms an arc that changes with the seasons, with longer, higher paths in summer and shorter, lower paths in winter, affecting daylight hours.
The Sun's apparent path through the sky in the northern hemisphere changes with the seasons due to Earth's 23.5° tilt on its axis and its orbit around the Sun. During summer in the northern hemisphere, the path is long, and the Sun rises north of east, culminating at a high point in the sky around noon before setting north of west, resulting in longer days. In contrast, during winter, the Sun takes a shorter path, rises south of east, and sets south of west, spending less time above the horizon and leading to shorter days. On equinoxes, approximately March 21 and September 21, the Sun rises directly east and sets directly west, spending equal amounts of time above and below the horizon.
At noon, the Sun reaches the highest point in its daily journey across the sky, crossing the north-south direction, usually to the south of the observer in the northern hemisphere. This height above the horizon at noon varies with the seasons, reaching its maximum during the summer solstice around June 21 and its minimum during the winter solstice around December 21.
