The two types of cells in nervous system are neural cells and glial cells.
Neurons: The major nerve cells that carry electrical and chemical messages from the brain to various regions of the body are known as neurons. They are specialized cells with the ability to create, send, and receive electrical signals, which are necessary for communication.
Glial Cells: Non-neuronal cells called glial cells provide crucial supporting roles in the nervous system. They offer physical support, regulate the chemical environment around the neurons, and aid in insulating and protecting the neurons. Glial cells come in a variety of forms, such as microglia, oligodendrocytes, and astrocytes. The blood-brain barrier is formed by astrocytes, which also serve to keep the right chemistry around neurons.

What is the definition of bone in biology?
Four different cell types can be found in bone, which is a mineralized connective tissue: osteoblasts, bone lining cells, osteocytes, and osteoclasts.
Osteocytes function as mechanosensors and orchestrators of the bone remodeling process, which is continuously carried out by the coordinated actions of bone cells, including osteoclasts and osteoblasts. Local and systemic elements that work together to support bone homeostasis regulate this process. Bone illnesses like osteoporosis can arise from an imbalance between bone resorption and creation. It has recently been discovered that there is complex communication between bone cells during bone remodeling. Examples include the interplay between osteoclasts and osteoblasts, which couples bone resorption to bone production. In addition, osteocytes release substances that affect osteoblast and osteoclast activity, and osteoclast-driven bone resorption occurs after osteocyte demise.

state three ways in which your external environment might vary
Homeostasis
Answer:
Explanation:
The three ways in which the external environment might vary and affect homeostasis are:
Temperature changes: Changes in the temperature of the environment can cause changes in the internal temperature of an organism, which can disrupt its homeostasis. For example, if the temperature drops too low, the organism might need to increase its metabolic rate to generate more heat.
Nutrient levels: Variations in the availability of nutrients can impact the homeostasis of an organism. For example, if there is a shortage of a specific nutrient, the organism might need to change its behavior or metabolism to acquire more of that nutrient.
Physical stressors: Physical stressors such as changes in pressure, light intensity, or exposure to toxic substances can affect an organism's homeostasis. For example, if the organism is exposed to high levels of light, it might need to increase its production of pigments to protect itself from damage.
which one of the types of proteins interacts directly with a stop codon?
Release factor types of proteins interacts directly with a stop codon.
A release factor is a protein that allows for the termination of translation by recognizing the termination codon or stop codon in an mRNA sequence. They are named so because they release new peptides from the ribosome.
A stop codon (also known as a termination codon) is a codon (nucleotide triplet within messenger RNA) that indicates the end of the current protein's translation process in molecular biology, more specifically in protein biosynthesis. A stop codon signals the end of this process by binding release factors, which cause the ribosomal subunits to dissociate and release the amino acid chain. The majority of messenger RNA codons correspond to the addition of an amino acid to a growing polypeptide chain, which may eventually become a protein.

[only include number, no symbols such as %]
In the case when 36% of the organisms have white petals and 48% have pink petals, that leaves 16% of the organisms with red petals.
One of two or more variations of the DNA sequence (a single base or a segment of bases) at a certain genomic region is referred to as an allele. For each given genomic site where such variation exists, an individual inherits two alleles, one from each parent.
The term "allele frequency" or "gene frequency" refers to the relative frequency of an allele (gene variation) at a particular locus in a population, given as a fraction or percentage.
Accordingly, the following formula may be used to determine the proportion of alleles in this population that represent red petals:

what is it about the fabrication of powdered gypsum into gypsum wallboard that makes it useful as a protection against fire spread?
The fabrication of powdered gypsum into gypsum wallboard makes it useful as a protection against fire spread because of its fire-resistant properties.
Gypsum wallboard, also known as drywall, is composed of gypsum, a naturally occurring mineral that has been ground into a fine powder and combined with other materials to form a panel.
When exposed to high temperatures, gypsum wallboard releases water vapor, which acts as a fire suppressant and helps to slow down the spread of flames. Additionally, gypsum wallboard also has a low ignition temperature, meaning that it is less likely to ignite in the first place.
In the event of a fire, gypsum wallboard can act as a physical barrier that helps to contain the fire and prevent it from spreading. When properly installed, gypsum wallboard can provide up to a 2-hour fire rating, which allows adequate time for occupants to evacuate the building and for firefighters to arrive and extinguish the fire.
Overall, the properties of gypsum wallboard make it an ideal material for use in building construction as it helps to reduce the risk of fire spread and provide a measure of fire protection for occupants.

assuming you put one bacterium in the bottle at 12 a.m., and the bacteria divide every 20 minutes, at what time will the bottle contain more than 1 million bacteria?
The bacterium bottle will contain more than 1 million bacteria after approximately 17 hours and 20 minutes.
If a single bacterium is placed in a bottle at 12:00 AM and it divides every 20 minutes, the number of bacteria will double every 20 minutes. Using exponential growth, the number of bacteria after 1 hour will be 2^3 = 8, after 2 hours it will be 2^6 = 64, and after 3 hours it will be 2^9 = 512. This process can be continued until the number of bacteria exceeds 1 million. With each hour, the number of bacteria will increase by a factor of 2^3 = 8, so after 17 hours the number of bacterium will be 8^17 = 130,727,840.
