Answer:
D. The cell membrane has been ruptured
Explanation:
The word lysis comes from the Greek word 'lusis" which means loosening. When used to described cells, it means the cells have burst or ruptured. Therefore, D is correct.
The cell ruptures when it is placed in a hypotonic solution, that is, a solution that has a lower solute concentration (and therefore a higher water concentration) than inside the cell. Water enters the cell by osmosis, eventually leading to the cell bursting.

arrange the organisms from fastest to slowest based on the the time theyd take to complete the 20th carnegie stage
Answer:
The correct answer is - Mouse - chicken - sheep - baboon - human
Explanation:
According the graph there are different group of organisms presents and the individual graph lines represnt the time they take to reach various or different carnegie stages.
To complete the 20th carnegie stage chicken takes 8 days aproximately, mouse takes 13 days and sheep takes 30 days according the graph representation.
Baboon takes almost 41 days to complete the 20th carnegie stage whereas human takes maximum time which is 55 days so , the corrcet order from fastest to the slowest would be as follows:
Mouse - chicken - sheep - baboon - human
Which of the following statements is NOT true with respect to global warming and
climate change?
1) the climate has been remarkably steady over the past 10,000 years
2)
variation in energy output from the Sun is too small to explain the current
warming trend
3)
over the previous 50,000 years the climate has undergone abrupt and
dramatic changes
4) carbon dioxide levels in the past correlate well with atmospheric temperature
5) current greenhouse gas levels are well within the Earth's long-term operating
range
Answer:
Earth's climate has changed dramatically many times since the planet was formed 4.5 billion years ago. These changes have been triggered by the changing configuration of continents and oceans, changes in the Sun's intensity, variations in the orbit of Earth, and volcanic eruptions.Over the last 100 years (1906–2005), global temperature has increased by 0.74°C. ... More regional changes have also been observed, including changes in Arctic temperatures and ice, ocean salinity, wind patterns, droughts, precipitations, frequency of heat waves and intensity of tropical cyclones.

b. change in state
c. foaming or bubbling
d. production of heat or light
Answer: weight. In the cylinder (graduated or not) the least dense layer is at the top (regardless of colour).
The composition of the material is unchanged by a physical change. Melting crayons is an example of a physical change.
Volumes are measured in litres or millilitres.
Change of state is not a chemical change.
Explanation: weight is a measure of the effect of gravity on mass

(what organelle is this) Passive transport is taking place across this thin cell covering causing the muscle cells to contract.
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, the cell organelle involved in transportation of molecules in the cell is the cell membrane. This cell membrane can be said to be cause of several forms of transportation in and out of the cell - this is because the membrane is a selective barrier. While some substances/molecules move through diffusion by moving with the concentration gradient (as in the case of passive transport, others move against the concentration gradient requiring energy to cause the transportation (as in the case of active transport).
Select the correct answer. Identify the region in the image where lighter elements such as hydrogen or helium are most likely to be found in a liquid or gases state?
Jupiter
Explanation:
Dj of series jf
The areas where hydrogen and helium are abundantly found is Jupiter, Saturn, Uranus and Neptune. This area is referred as the gas giants.
What are the uses of hydrogen?Hydrogen is the lightest chemical element denoted by symbol H. It is represented as H2 in gaseous form. Hydrogen has the property of combustion.
Hydrogen is widely used as fuel and is helpful in generating heat and electricity. Hydrogen has its abundant usage in petroleum refining industry and in the production of fertilizers.
Hydrogen is used the commercial production of ammonia by Haber's process. It is used in various chemical reactions such a methanation, hydrocracking, hydrodesulfurization etc.
It is also used in hydrogenation reaction of fats and oil. Hydrogen is predominantly used as fuel for rockets. It is used in welding industries as well as in the reduction of metallic ores.
Thus, hydrogen is crucial for many chemical reactions in nature.

CTLs can kill cells infected with viruses or intracellular bacteria. They also can kill cancerous cells. How might an infected or cancerous cell evade immune control by CTLs?
a. Increased expression of MHC class II molecules.
b. Increased expression of MHC class I molecules.
c. Decreased expression of MHC class I molecules.
Answer: The correct option is C (Decreased expression of MHC class I molecules.)
Explanation:
The lymphocyte is the major type of white blood cells which is divided into two:
--> B Lymphocyte and
--> T Lymphocyte
The T Lymphocyte is further divided into two namely:
--> T helper cells and
--> Cytotoxic T Lymphocyte (CTL)
The T lymphocyte cells recognize a non self target such as a pathogen only after pathogen has been processed and it's antigen presented in combination with a complex known as the Major histocompatibility Complex ( MHC). There are two types of MHC which includes Type 1 and Type 2 MHC.
The cytotoxic T Lymphocyte only recognize antigen combined with Class 1 MHC.
Some virus mechanism of action, while invading some target cells, is to reduce the normal levels of surface class 1 MHC in order to evade or escape the immune control by cytotoxic T Lymphocyte. Therefore the correct statement is decreased expression of MHC class I molecules.

If you’re one of the hundreds of millions of Americans that listen to true crime, chances are you’ve heard about a case that was solved by forensic dentistry. Forensic dentistry, also called forensic odontology, is the application of dentistry within the criminal justice system. It is typically used to identify unknown victims or perpetrators. More broadly, it refers to the proper handling and examination of dental evidence, which is later presented in a court of law. Forensic odontology is also often used to identify the victims of mass disasters.
