Answer:
Explanation:
our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
To deliver appropriate oxygen for respiration and cell mitosis.
Fat that has been digested is packaged in protein- and phosphorus-containing lipoproteins which travel from your lymph to your bloodstream. These are called chylomicrons.
<h3>What are chylomicrons?</h3>
- Chylomicrons are large triglyceride-rich lipoproteins produced in enterocytes from dietary lipids—namely, fatty acids, and cholesterol.
- Chylomicrons are composed of a main central lipid core that consists primarily of triglycerides, however like other lipoproteins, they carry esterified cholesterol and phospholipids.
- Chylomicrons exit the enterocyte via the lacteals into the systemic circulation.
- They are acted on by LPL with its cofactor Apo-CII, which cleaves off FA moieties, which in muscle and adipose tissue are immediately mobilized for energy or stored for future use.
- So digested fat is transported through lymphatics as chylomicrons.
