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

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.

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?​

Answers

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.

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​

Answers

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.

Explain how one change in the Earth's biosphere can
cause changes in other Earth systems.

Answers

Answer:

interaction in the Earth's biosphere cause the change in other Earth system as the biosphere and atmosphere are dynamic, constantly reflecting these interaction. and Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.

The Earth's biosphere is closely interconnected with other Earth systems, such as the hydrosphere (water), atmosphere (air), and geosphere (land). Changes in one part of the Earth's biosphere can have significant impacts on other Earth systems, and vice versa

What is a biosphere?

Biosphere means interactions with each other and their physical environment.

For example, changes in land use, such as deforestation or urbanization, can affect the Earth's water cycle and climate. Deforestation, for example, can lead to increased runoff and erosion, which can alter the availability and quality of water in an ecosystem. Deforestation can also lead to an increase in atmospheric carbon dioxide, as trees and other vegetation absorb and store carbon dioxide during photosynthesis. This can contribute to global warming and climate change.

Similarly, changes in the Earth's climate, such as an increase in temperature or a change in rainfall patterns, can affect the biosphere. Warmer temperatures can lead to the range expansion of certain species and the loss of habitat for others. Changes in rainfall patterns can affect the availability of water for plants and animals, which can lead to changes in the distribution and abundance of species in an ecosystem.

Proteins are made on cell structures known as.…

Answers

Answer:

Ribosomes

Explanation:

Ribosomes are organelles made of ribosomal RNA (rRNA) and protein. They exist in the cytoplasm of the cell and are the site of protein synthesis in all cells. Ribosomes read the codons in mRNA and catalyze the creation of peptide bonds between the appropriate amino acids, forming polypeptide chains.

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). ​

Answers

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.

A segment of DNA

Explanation:

Genes are parts of DNA

A gene is a segment of the DNA (deoxyribonucleic acid). DNA is the genetic material of the cell which contains the information for the development of different characteristics in an organism. Thus, the correct option is B.

What is a Gene?

A gene is the basic unit of heredity in an organism. It can also be defined as the molecular gene which is a sequence of nucleotides in the DNA molecule that is transcribed to produce a functional RNA which synthesizes a protein. There are two main types of molecular genes which include protein-coding genes and the noncoding genes.

Protein-coding genes or exons are the regions in the DNA which encodes for the synthesis of protein and the non-coding genes or introns are the segments of the DNA which does not code for any protein and thus are spliced in the post-transcriptional mechanism.

Therefore, the correct option is B.

Place two cups of equal size and have equal amount of ice in the two separate playhouse in order to find out which playhouse is more warmer and which is less. Note the time and after sometime check the cups of ice in both playhouses.

That playhouse in which all the ice turns into water than the other one is considered warmer playhouse as compared to the other one because high temperature melts ice very quickly so we can conclude that the ice melts in the playhouse quickly is considered a warmer playhouse.
