Answer:
d. the structure and chemical properties of the plants
Explanation:
The most important safety consideration to grow plants in a classroom is to have knowledge of the structure and chemical properties of the plants.
The correct option is D.
What is important to consider for plant maintenance?
There are various kinds of plants that grow in various climatic conditions. All these varieties require different conditions for their growth.
The conditions required for growth depend on the structure and chemical properties of the plants. The amount of sunlight, water and nutrition required differs in these physical and chemical and chemical properties.
The kind of soil required is also different according to the different kinds of plants. Soil availability depends on the geographical location. Therefore, to grow a particular kind of plant it's important to ensure that the soil required for its growth is available in that geographical location.
So, knowledge of all this is required to grow and maintain plants in a classroom.
Therefore, the correct option is D.

Which of the following is not a way in which antihistamines may affect transduction pathways? (1 point) They prevent enzymes from transforming histidine into histamine. They prevent release of histamine by blocking signal transduction. They reduce cellular response by blocking signal transduction. They reduce histamine in the blood by binding to and destroying it.
Answer:
The correct answer is : They reduce histamine in the blood by binding to and destroying it.
Explanation:
Antihistamines are type of drugs that inhibits release of histamine by binding to histamine receptors and suppress the transduction pathways of histamine.
They blocks the enzymes from transforming histidine into histamine and reduce cell response by blocking histamine-induced cascade signal transduction. These are use to treat allergies, congestion, hay fever and other allergy responses.
Thus, the correct answer is : They reduce histamine in the blood by binding to and destroying it.

12. An example of a hydrogen bond is the bond between?
The Hydrogen of one water molecule and the Oxygen of another water molecule.
The two hydrogen atoms in a molecule of hydrogen gas (H2).
Carbon and Hydrogen in a molecule of methane (CH4)
Sodium (Na) and Clorine (CI) in salt.
Answer:
The hydrogen of one water molecule and the oxygen of another water molecule
The Hydrogen of one water molecule and the Oxygen of another water molecule.
Hydrogen bonding happens when a hydrogen atom from one molecule attracts an electronegative atom like oxygen or nitrogen in another. Water is cohesive and sticky because the hydrogen atom in one water molecule bonds with the oxygen atom in another.
Hydrogen bonding affects the structures and characteristics of molecules and compounds in nature and is important in many biological and chemical processes. Therefore, the Hydrogen of one water molecule and the Oxygen of another water molecule.

Which of the following organisms breaks down dead material and returns the substances to the environment?
Answer:
C.Bacteria
Explanation:
The organism that breaks down dead materials are decomposers, ofc lion and vulture arent decomposers. Algae also a producer and not a decomposer. So the only answer is bacteria, bacteria is a small organism that eat and decompose dead things :)
The organism that breaks down dead material and returns the substances to the environment is BACTERIA, which is option C.
BACTERIA especially those that lives in soil are saprophytic in nature. This means that they feed on dead decaying organisms and their excreta (wastes such as urine and faeces) and bring about their decay or decomposition. This occurs through the following'
• they secrete enzymes onto their food source such as a decaying leaf,
• these enzymes break down complex compounds like carbohydrates and proteins into simple inorganic compounds.
• a lot of chemical energy is lost as unusable heat energy.
• the decomposers (bacteria) only absorb a small amount of nutrients and energy for their use
• the rest is then released into the soil, air and water.
Therefore, the organism that breaks down dead material and returns the substances to the environment is BACTERIA.

Identify ways in which all biological systems from cells and organisms to populations, communities and ecosystems are affected by complex biotic and abiotic interactions involving exchange of matter and free energy
Answer:
Explanation:
Cell which is the basic unit of life is affected by the interactions with biotic and abiotic factors such as temperature, sunlight. Organisms are made up of cells and they respond differently to temperature changes, sunlight, water availability. Some cell perform better at some certain range of temperature while some cannot.
Organism itself are affected by the interaction of some of this factors this include water and nutrients availability. Distribution of organism in a particular habitat is greatly influenced by availability of water and nutrients it lead to competition for survival among organism. Population density and species diversity also influence community and ecosystem. Population determines how resources is allocated in a community and it affect the activities of the organism in that domain or territory.
When a chance mutation modifies a virus to attach to a new host species, it is called
Answer:
gain-of-function
Explanation:
Gain-of-function mutations represent a type of genetic change that may confer a new function to the gene that undergoes the mutation. In this case, a gain-of-function mutation conferred to the virus an adaptive advantage by allowing it to encode a new protein which is capable of attaching to the cell membrane of a new host. In this regard, it is important to note that loss-of-function mutations are quite common in nature, while gain-of-function mutations are relatively rare.
A sample of an unknown liquid has a volume of 24.0 mL and a mass of 6 g. What is its density?
Answer:
0.25 g/cm³ or 0.25 g/mL
Explanation:
Density = Mass / Volume, so you would then plug in your two variables.
D = 6 g/ 24 mL = 0.25 g/mL or 0.25 g/cm³
Answer:
15.607 lbs or 250 g/L
Explanation:
Density is calculated by dividing the mass (6 g.) by the volume (24 mL). With that knowledge you come to the answer which is 250 g/L which is the measurement I'm assuming you'd need considering you're dealing with a liquid.
If you need a different measurement of density, let me know.

Why don't prokaryotic cells divide through mitosis? Mitosis requires a cell membrane, and prokaryotes don't have a cell membrane. Mitosis and cytokinesis require cytoplasm, and prokaryotes don't have cytoplasm. Mitosis is division of the nucleus, and prokaryotes don't have a nucleus. Mitosis requires DNA and chromosomes, and prokaryotes don't have chromosomes.
Answer:
Prokaryotic cells, on the other hand, do not undergo mitosis and therefore have no need for a mitotic spindle.

until it reaches about 4° C.
A. decreases
B. increases
C. decreases and increases
D. stays the same
As water is cooled its density increases 4 degrees Celsius is reached
Cooling causes water to slow down at a faster rate occupying a smaller rate as hot water is less dense than the room temperature as cold water is denser and will freeze at room temperature.
Water being a solvent has various physical and chemical properties.
Water has to condense to a certain point to produce the desired effects.

Explain Give two examples of how abiotic factors are influenced by biotic factors?
Answer: If this doesn't help just let me know
The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controlling the biotic factors of an environment.
The interaction between humans and water and plants and soil are examples of the influence of biotic factors on abiotic ones.
Biotic and abiotic factors are biological terms to refer to:
Abiotic factors: are the set of non-living physical and chemical components of an ecosystem.Biotic factors: are the set of living components of an ecosystem.According to the above, living beings (biotic factors) can affect abiotic factors such as water because they contaminate it with chemicals or waste.
Also, plants (biotic factors) see the soil (abiotic factors) because they provide them with nutrients.
