What are the types of energy ?The energy can be defined as ability to work or produce action and / or movement and manifests itself in many different ways, such as body movement, heat, electricity, etc.
The different types of energy include Kinetic energy which is associated with the movement of bodies. Potential energy which is stored by virtue of a body's position relative to its surface is also called gravitational potential energy.
Thermal Energy or Heat can be defined as the energy associated with the kinetic energy of the molecules that make up an element, it can be manifested if there is a temperature difference between two bodies.
Chemical energy released or formed from chemical reactions, Solar energy from sunlight. This form of energy is used to generate electricity through photovoltaic plates, for example.

What do biologists call the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli? A. first responders B. mitochondria C. receptors D. organelles
Answer: Receptors.
Explanation: Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Receptors are the specialized cells in the nervous system that detect heat, pressure, and other environmental stimuli.
What are receptors?Receptors are proteins, usually cell surface receptors, which bind to ligands and cause responses in the immune system, including cytokine receptors, growth factor receptors and Fc receptor.
Moreover, receptors are bound up with functions such as cell activation, cell adhesion and signaling pathways. These functions play a role with the help of receptors.
Therefore, cell activation including T cells, dendritic cells, B cells, granulocytes and NK cells, is an important process in innate and adaptive immune system.

Question 1: One of the central themes in biology is how DNA, RNA, and proteins are related. Describe how genetic information flows between those types of molecules. Include the results of the processes of transcription and translation? ( Will Mark Brainliest if answered correctly. Do Not Repost Someone Else's Answer that is already on Brainly or any other websites please).
Answer:
Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
Answer:
DNA is the code that stores all our genetic information. When making a protein, DNA has to go through transcription and then translation. In transcription, an the genetic code of DNA is copied to mRNA, with the aid of an RNA polymerase protein which attaches single RNA units to the mRNA strand as the RNA polymerase moves on the DNA. Note that instead the letter T, RNA contains U. This occurs in the nucleus. The mRNA travels to the cytoplasm to a ribosome. The RNA also trims itself, removing parts that it does not need, and keeping parts for translation. The ribsomes use tRNA attached to amino acids to assemble the protein chain and translate the mRNA into proteins. As the amino acid chain, or polypeptide forms, a protein comes to be. However, there may be mutations, resulting from translation or transcription and sometimes these mutations may cause harmful affects.

The diagram shows an ocean food web. Which organism is a primary consumer? krill elephant seal Killer whale Elephant seal O squid O penguin Penguin Leopard seal Squid Cod Krill Zooplankton Phytoplankton
Answer:
Krill
Explanation:
If you look at the diagram for this assignment, you can see the main organism that produces its own food is the phytoplankton. The animal that eats that organism is called a primary consumer. So, if you were to follow the arrow from the phytoplankton (or the producer), it would lead you to the zooplankton, krill, and cod. Since there are only one of these primary consumers as the choices, you would pick the only one available for the multiple choice, which would be krill :D
Answer:
A. krill
Explanation:
None of the other organisms are primary consumers.

you don need to actually chew the bread. you can just break it up into smaller pieces. which variable will you change in your investigation?
Answer: The type of bread (independent variable)
Explanation:
You can just change the type of bread you are eating and just hold it in your mouth to test your hypothesis of not having to chew the bread. It’s the easier thing to change when making the experiment. Now your bread is your independent variable because you are not changing anything else but the type of bread. Not sure if your question is talking about the technical terms for the variable or what actual variable in the experiment, so I put down both.

describe the mechanism of blood sugar regulation (20 marks)
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p

Answer: different species
Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species
However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.
What shows the low light in the evening?The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.
As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.
