Explanation:
Abiotic factor: Nonliving chemical and physical parts, just like temperature and soil in an ecosystem
As far as the ecosystem is concerned, soil and temperature are abiotic factors.
The biotic factors of the ecosystems are living factors. They consist of all the living organisms and their relationship with each other in the ecosystem.
The abiotic factors are also known as nonliving factors. They include soil, temperature, pressure, salinity, wind, etc.
Thus, temperature and soil are parts of the nonliving factors of the environment.

Ecology is the study of interactions among organisms and their environment including its living and nonliving parts.
Answer: A. Ecology
Explanation:
Ecology is the investigation of how living beings associate with each other and with their physical condition. The conveyance and bounty of living beings on Earth is moulded by both biotic, living-life form related, and abiotic, nonliving or physical, factors.
Ecology is learned at numerous levels, including creature, populace, network, biological system, and biosphere. Water accessibility is a case of an abiotic, or nonliving, factor that can influence dispersion of creatures.
Accessibility of supplements given by different life forms is a case of a biotic, living-creature related, factor that can impact appropriation.
Ecology is the study of how organisms interact with each other and their environment, inclusive of both living and nonliving components. Other subjects like economics, geology, and sociology might touch on interactions, but not specifically within biological ecosystems.
Explanation:The study of interactions among organisms and their environment, which includes both living and nonliving components is known as ecology. This field examines how individual organisms, populations, communities, and ecosystems interact with one another and their environment. It's important to note that while economics, geology, and sociology may involve some study of how entities interact, these are not primarily focused on interactions within the natural environment or among organisms, making ecology the most suitable answer to your question.

Which of the following are affected by the order of amino acids in a protein? Select all that apply.
A proteins shape
A proteins structure
A proteins function
PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!
The structure and function are affected by the amino acids order in a protein.
Explanation:The succession of a protein is controlled by the DNA of the genes that encode the protein. An adjustment in the gene's DNA arrangement may prompt an adjustment in the amino acid grouping of the protein. In any event, changing only one amino acid in a protein's grouping can influence the protein's general structure and capacity.
For example, a solitary amino acid change is related to sickle cell frailty, an acquired infection that influences red platelets. In sickle cell frailty, one of the polypeptide ties makes hemoglobin, the protein that conveys oxygen in the blood has a slight succession change. The glutamic acid that is regularly the 6th amino acid of the hemoglobin β chain is supplanted by a valine.
Answer:
****I put the answer janehill33 gave and I got the question incorrect. Therefore I thought that I would come and share the correct answer! People please stop giving the wrong answer.
The answer is Shape, Structure, and Function,
Explanation:
A protein's three-dimensional shape and the way its different amino acids are positioned within that shape make up its structure. A protein's structure depends on the order of amino acids in its chain. This is because as a protein folds, the amino acids interact with each other and with nearby molecules in the cell.
Each type of amino acid has unique properties and interacts with molecules in a different way. These interactions determine the final shape of the protein. For example, some types of amino acids stick together, which causes the protein's amino acid chain to bend or loop. Other types of amino acids are repelled by nearby water molecules. This causes parts of the protein to fold inward.

Which factors are used to differentiate climate regions? Check all that apply. rainfall plant life animal life temperature wind
Answer:
rainfall
temperature
Explanation:
To differentiate climate regions, factors such as rainfall, temperature, wind, along with plant and animal life should be considered. Abiotic factors, including elevation, latitude, and wind systems, significantly influence the climate, which in turn affects the distribution of biomes. Variation in these elements results in diverse climates across different geographic areas.
Explanation:Factors used to differentiate climate regions include rainfall, temperature, wind, as well as plant life and animal life. These are crucial elements that define the weather patterns and overall climate of a region. Climate is the statistical summary of temperature, humidity, atmospheric pressure, wind, rainfall, and other meteorological measurements in a given region over long periods. Climate factors like rainfall, temperature, and wind are abiotic factors that significantly influence the distribution of biomes in various regions.
Different abiotic factors, especially temperature and precipitation, account for the variations in climate across various biomes. Factors such as elevation, latitude, wind systems, ocean currents, the position on a continent, and mountain barriers also play pivotal roles in influencing a region's climate. For example, high elevations typically have cooler temperatures and wind systems can bring about various weather patterns, leading to different climates in adjacent regions.

answer-solubility
When a substance undergoes a physical change, its chemical composition remains the same, and there is no formation of new substances.
A physical change is a process in which the physical properties of a substance are altered, but its chemical composition remains unchanged. In other words, the substance does not undergo a chemical reaction, and no new substances are formed. Instead, the changes observed are related to the state of matter or the physical properties of the substance.
Examples of physical changes include changes in state (such as melting, freezing, boiling, or condensing), changes in shape or size (like cutting, crushing, or bending), and changes in appearance (such as dissolving, mixing, or separating). These changes are usually reversible, and the substance can often be restored to its original state by reversing the process.
One characteristic of physical changes is that they do not involve the breaking or forming of chemical bonds between atoms or molecules. The individual particles of the substance (atoms, ions, or molecules) remain the same before and after the change. For example, when ice melts into liquid water, the water molecules remain H₂O molecules throughout the process.
In contrast, chemical changes (also known as chemical reactions) involve the rearrangement of atoms and the formation of new substances with different chemical properties. In a chemical change, the original substances are consumed, and entirely new substances are produced.
Understanding the difference between physical changes and chemical changes is essential in various scientific fields, including chemistry and materials science. It helps scientists distinguish between alterations in the physical appearance of a substance and fundamental changes in its chemical nature.

Harrison wanted to find out what soil works best for growing roses. He grew them in potting soil, clay, sand, and soil he found outside his yard. After one week, he measured their height and how many leaves they had. What are the independent variable, dependent variable, control, and constants?
Final answer:
The independent variable in Harrison's experiment is the type of soil, the dependent variables are the height and number of leaves of the roses, and the control is a separate group of roses grown in a standardized soil. The constants include factors like water, sunlight, temperature, and planting conditions.
Explanation:
The independent variable in Harrison's experiment is the type of soil (potting soil, clay, sand, and soil found outside his yard), as this is the factor that is being changed or manipulated. The dependent variables are the height and number of leaves of the roses, as these are the variables that are measured and are expected to be influenced by the type of soil. The control in this experiment would be a separate group of roses that are grown in a standardized soil that is known to be suitable for rose growth.
The constants in Harrison's experiment would be factors that are kept the same across all groups of roses, such as the amount of water, sunlight, temperature, and planting conditions. These constants ensure that any differences observed in the dependent variables can be attributed to the independent variable (type of soil) and not other factors.
Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.
Enzyme activity decreases at these temperatures
At these temperatures plants wilt
Chlorophyll cannot absorb energy from the sun at these temperatures
The cytoplasm of the plant cell cannot function
Answer:
Enzyme activity decrease at these temperatures.
Explanation:
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH. In dark reactions carbon is fixed using the ATP and NADPH.
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about 10°c - 20°c. At low temperatures and high temperatures enzyme activity is less efficient.
At a temperature above 38°c and below 0°c enzyme activity decreases.
Induced pluripotent stem cells are cells for adults that of been reprogrammed to imitate embryonic stem cells. why might induced pluripotent stem cells be a valuable tool in science and medicine?
First, by their nature, pluripotent stem cells can potentially be used to create any cell or tissue the body might need to counter a wide range of diseases, from diabetes to spinal cord injury, to childhood leukemia, to heart disease.
Second, pluripotent stem cells can potentially be customized to provide a perfect genetic match for any patient. This means that patients could receive transplants of tissue and cells without tissue matching and tissue rejection problems, and without the need to take powerful immune-suppressing drugs for the rest of their lives. Although this vision hasn’t yet been achieved, researchers at Boston Children’s Hospital have successfully treated mouse models of human disease using this strategy and hope that the same can be done with patients.
Third, pluripotent stem cells make excellent laboratory models for studying how a disease unfolds, which helps scientists pinpoint and track the very earliest disease-causing events in cells. Immune deficiencies, Type 1 diabetes, muscular dystrophy, and myriad other disorders are rooted in fetal development. In the lab, researchers can recapture these early originsobserving where the first muscle cell comes from, or the first blood cell, and how this differs when the patient has a genetic disease. Using this information, doctors may be able to intervene and correct the genetic defect before the disease advances.
Each type of pluripotent stem cell has different characteristics that make it useful in different ways, and each has different lessons to teach.
Induced pluripotent cells offer a unique chance to model human disease and are already being used to make new discoveries about premature aging, congenital heart disease, cancer, and more. Because they’re made from a person’s own cells, they can potentially be manipulated to fix the disease-causing defect and then used to create healthy cells for transplant that won’t be rejected by the immune system. Many people also see cells as a positive alternative to pluripotent stem cells from embryos or eggs.
Embryonic stem cells are the gold standard for the biological concept of pluripotency. Scientists are working with ES cells to learn more about what endows a cell with pluripotency and to discover safer, better ways to created cells. Each type of cell is important for different reasons:
cells made from donated early embryos are irreplaceable tools for understanding the earliest stages of human development and how specific tissues form. Because they’re not customized to individual patients, their value is mainly in research.
cells made through nuclear transfer, like cells, offer the opportunity to create customized, rejection-proof cells and tissues for transplantation. ntES cells are thought to be the most genetically pristine source for creating genetically-matched cells, so may provide a faster and safer route to the clinic.
ES cells made through parthenogenesis (pES cells) also offer the opportunity to create customized, rejection-proof cells. Though less genetically pristine than ntES cells, they are less technically cumbersome to produce. Through genetic typing, they could potentially be banked to create a selection of off-the-shelf cell-based treatments.

Are atoms positive, negative, or neutral in charge? Explain.
Atoms are neutral in charge because the number of protons (positive) equals the number of electrons (negative), balancing each other out. However, the neutrality can change if an atom gains or loses electrons, turning into an ion.
Explanation:Atoms are neutral in charge. Each atom consists of protons, neutrons, and electrons. Protons carry a positive charge and electrons carry a negative charge, while neutrons are neutral and have no charge. An atom is neutral because the number of protons (positive charges) is equal to the number of electrons (negative charges), balancing each other out. The neutrality of an atom can change, if it gains or loses electrons, becoming an ion. But overall, an isolated atom is neutral in charge.

a. used for insulation in Arctic animals.
b. used for long-term energy storage in hibernating animals.
c. needed to form cell membranes.
d. chained together to form proteins.
Answer:

Explanation:
Proteins are not made of lipids chained together but rather of amino acids chained together. Lipids are made of fatty acid chains joined to various molecules - like glycerol and phosphate that make phospholipids - Phospholipids make up the cell membrane of most cells. Fats are deposited under the dermis of the skin for insulation and this layer is thicker in animals that live in the cold regions. During starvation, these fats are taken from their reserves and broken down to provide energy for the body.
