The correct option is (c) LDL consists of cholesterol and protein.
One of the five main categories of lipoproteins, low-density lipoprotein (LDL), transports cholesterol throughout the body to the areas where it is required for cell repair and deposits it inside the artery walls. They need to be bound to proteins in order to pass through the hydrophilic blood.
The hydrophobic core of the LDL particle is made up of fatty acid esters of cholesterol, while the outer membrane is made up of unesterified cholesterol. The membrane contains a single copy of the hydrophobic apo-B protein, which facilitates the binding of LDL particles to particular cell-surface receptors.
Hence, LDL consists of cholesterol and protein.

A somatic cell is a cell that is any of the 22 chromosome pairs that aren’t reproductive cells. So, these cells would have the full 26 chromosomes that a frog usually has.
However, since an egg cell is a reproductive cell and needs to combine with another reproductive cell to create one whole combined cell and organism, it would only have 13 chromosomes. The egg cell is like half of a somatic cell, so it will have half of however many the somatic cell will have.
Step 1-Light Dependent
CO2 and H2O enter the leaf
Step 2- Light Dependent
Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2
Step 3- Light Dependent
The electrons move down to enzymes
Step 4-Light Dependent
Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-Light independent
The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.
Step 6-Light independent
The calvin cycle converts 3CO2 molecules from the atmosphere to glucose
calvin cycle
The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.
The Earth's mantle is the layer of rock just below the Earth's crust. Just under the crust, it is solid. It is very hot, and the other part of the mantle is soft, kind of like melted candy.
The Earth's mantle is rock-hard but it actually flows around the outer core, moving about as slowly as your fingernails grow. The mantle tends to be 2,900 kilometers thick, and makes up 84% of Earth's total volume.
Answer:
You could say, when conducting research scientists use the scientific method to collect measurable empirical evidence in an experiment related to a hypothesis often in the form of an if/then statement the results aiming to support or contradict a theory.
