The answer is C magma is a type of liquid and cools down making a rock form. which is the same as <span>crystallization</span>
4. Collect and measure the amount of rain in March and in April
Explanation - Rainfall can be measured by instruments like rain gauge. But in case rain gauge is not available then the rain water can be collected in a vessel having funnel at the top.
Measuring the amount of water falling each day in the month of march and april would give the idea about which month has more rainfall. The measurement might not be accurate but it gives a brief idea about how much centimeter of rain is occurring in both the months.
<span>A metal, an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.</span>
Answer:
D) bilayer membranes
Explanation:
Two lipidic bilayers compose the cell membrane. There are also proteins and glucans incrusted in between. Lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. Lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane. Membranes are fluid, which means that the composing molecules can move through them.
Lipids can easily change places with other neighboring lipids by lateral diffusion in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer but not as easily as lateral diffusion. Jumps between monolayers are infrequent as the lipidic polar heads meet the fatty acid barrier.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
High blood levels of the amino acid homocysteine
have been linked to increased risks of cardiovascular disease.
<span>Cardiovascular disease is a disease related
to heart, in which vessels become narrowed or blocked and these can lead to
heart attack or stroke.
Homocysteine is an amino acid and its important source
is meat, we get this from eating meat and when the level of these amino acid
increases in the blood, it leads to heart disease.</span>
