The Jurassic period had angiosperms, while the Cretaceous did not.
b.
Pangaea split during the Jurassic period.
c.
There were dinosaurs in the Jurassic period, which went extinct in the Cretaceous period.
d.
Conifers and ferns were present in the Jurassic period, but not in the Cretaceous period.
The Cretaceous period differs from the Jurassic period in that there were dinosaurs in the Jurassic period that became extinct in the Cretaceous period, as the dinosaurs that were available in the Jurassic period are in Option C.
They were significant as they were the dominant land animals during the Mesozoic Era and evolved into a wide variety of forms, from the large, long-necked sauropods to the small, agile raptors, and they gave insights into the evolution of life on Earth. Dinosaurs help scientists understand the patterns and processes of evolution, including how animals adapt to changing environments and showed the link with birds.
Hence, the Cretaceous period differs from the Jurassic period in that there were dinosaurs in the Jurassic period that became extinct in the Cretaceous period, as the dinosaurs that were available in the Jurassic period are in Option C.

the answer is correct I just put a star by accident hahahah
Answer:
is 1%
Explanation:
Answer:
The seals would receive about 1% the amount of energy as the crabs.
Explanation:
The seals would receive about 1% the amount of energy as the crabs. The 10% rule says that as you move through an energy pyramid, the available energy decreases by about 90%, leaving 10% available energy for the next trophic level. Since the energy moved through two tropics levels, there is only about 1% available: 100% to 10% to 1%.

Answer:
Phospholipids
Explanation:
Cell membrane is an important type of cellular structure in the cells of living organisms. It functions to allow selective movement of materials or substances in an out of the cell.
Cell membrane is made up of a phospholipid bilayer and proteins embedded in it. Phospholipids form this lipid bilayer which is the basic structure of the cell membrane. The membrane also contains cholesterol molecules which help in keeping the membrane fluid consistent.
Additionally, the membrane also contains proteins whose function is to enhance the transportation of materials across the membrane.
The answer is Visceral mass.
The visceral mass also called visceral hump, it is considered as ‘body’ of the mollusks. Examples of the mollusks are Sepia, Pila, Unio. The visceral mass is located below the mantle and above the muscular foot. It includes all the vital organs such as the respiratory organs, the nervous system, the digestive organs, excretory organs of a mollusk.
Answer:
The backbone of the double helix is made up of SUGAR molecules and PHOSPHATE groups, and the two chains are joined together by hydrogen bonds between the NUCLEOTIDE BASES
Explanation:
DNA is a double helix structure. It looks similar to a twisted ladder. The backbone is like the sides of the ladder. They are made up of sugar molecules called deoxyribose and phosphate linked together. The nucleotide bases make up the rungs. Each rung is made up of 2 complimentary bases that are held together by hydrogen bonds.
The backbone of the double helix is made of sugar-phosphate molecules and groups. The two chains are joined by hydrogen bonds between the nitrogenous bases. These bases are adenine (A), thymine (T), cytosine (C), and guanine (G)
The backbone of the double helix, such as DNA, is made up of sugar-phosphate molecules and sugar-phosphate groups, and the two chains are joined together by hydrogen bonds between the nitrogenous bases
More specifically, the sugar is deoxyribose, and the phosphate group is a component of each nucleotide. The strands of the helix run in opposite directions, making them antiparallel. The nitrogenous bases that join the two strands are adenine, thymine, cytosine, and guanine - adenine always binds with thymine and cytosine with guanine.
