The smallest item in the list would be organelles. Organelles are tiny structures within a cell, that help it to function. Example of organelles are-- nucleus, mitochondria, cell membrane to name a few. Cells are the basic unit of structure and function of all living things, therefore, cells would have to be placed second. They are microscopic. A group of similar cells that work together to perform a specific function, is known as a tissue. Therefore, tissue is next largest. Examples of tissues include, muscle tissue, epithelial tissue, adipose tissue. When different types of tissues work together to perform a function in the body, this group of tissues forms an organ. An example of an organ is the heart. Inside the heart are many types of tissue-- cardiac muscle,nerve, blood, connective, etc. The job it performs is to pump blood. When various organs work together to perform a specific function in the body, this makes up a system. An example is the circulatory system. In this system are many organs that work together. Arteries, veins, capillaries and heart are all part of the circulatory system. Its job is to circulate blood containing nutrients and oxygen to cells and to pick up cellular wastes. All the systems of the body comprise the organism. An organism is a living thing. It can be as tiny as a microbe, or a complex as a human. When referring to a multicellular organism, the correct order from smallest to largest is-- organelle, cell, tissue, organ, system, organism
Answer:
Most birth defects can't be prevented, but you can take some steps to reduce the likelihood of environmental effects. Remember to always discuss your concerns with your healthcare provider and follow their instructions regarding screening tests, medications, etc.
Explanation:
Answer:
Correct choice should be:
"SGSG"
Explanation:
The cell cycle consists of G1, S, G2 and M phase. The former three phases include the interphase and M phase is the dividing phase of cell . G1 prepares cell for DNA synthesis. S phase is the phase where DNA replication takes place. G2 phase prepares cell for cell division or M phase.
G1 phase preceeds replication or S phase and G1 phase licences DNA replication.
During other phases of cell cycle, ORC complex masks origin of replication. ORC phosphorylation takes place at S phase, which removes this omplex and unmasks origin of repication site so that replication machinery can bind to it.
DNA helicase activation: S phase
DNA helicase deposition on DNA at the replication origins: G phase (actually G1)
ORC phosphorylation: S phase
Licensing of replication origins : G phase (actually G1)
Hence correct choice should be:
SGSG
Positive impacts of genetic engineering:
• New products are created such as food with higher nutrition values, drugs that are more effective and safer
• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.
Mass does remain constant. A is true.
Only the form changes. ( I take that means that a solid is different from a liquid) and that is also true.
Kinetic energy changes. This one is kind of iffy. that means that the temperature will change. Temperature is a measurement of KE. If the change is so much as 1 degree or 1/2 a degree or a millionth of a degree, this is true. It's not very likeable though.
The last one is false. Chemical reactions produce new things. State change only produces something going (say) from a liquid to a solid. There's nothing new being created.
