Answer:
Explanation:
Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.

cholesterol is needed to build call membrane.what is cholesterol
Answers
Answer:
Answer below
Explanation:
Cholesterol refers to a group of chemical compounds. A sterol is a kind of lipid, and cholesterol is one of them. All animal cells produce cholesterol, which is an important structural component of cell membranes. It is a yellowish crystalline solid when chemically separated.
a sterol-type molecule present in most human tissues. Cholesterol and its derivatives are key components of cell membranes and precursors of other steroid chemicals, but a high proportion of low-density lipoprotein in the blood (which delivers cholesterol to the tissues) is linked to a higher risk of coronary heart disease.
Cholesterol is a waxy, fat-like molecule found in all of your body's cells. Cholesterol is required by your body for the production of hormones, vitamin D, and chemicals that aid digestion. Your body produces all of the cholesterol you require.

Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
Mitochondria responsible for energy productionRibosomes responsible for protein synthesisCell wall that protects the cell from the environmentThe Golgi apparatus that packages proteinsIt also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.

These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters. Sharpening an image under high magnification used the Find adjustment knobs. The part of the microscope that holds the Microscope slide is called the stage.

Why are hydrogen bonding and popularity so important for water molecules?
Answers
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

functions of bowman's capsule and materials absorbed in the bowman's capsule
Answers
Answer: The structural and functional unit of the kidney is called a nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowman’s capsule and a tuft of leaky blood vessels encapsulated by the Bowman’s capsule.
Glomerulus capsule is a tuft of capillaries that are found inside the capsule of Bowman. Bowman’s capsule is a sac-like organ that is present at the nephron’s tabular end, encapsulating glomerulus in it.
The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomerulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea, etc.

C.
Explanation:
Because for answer A, only eukaryotes have DNA, also for B, only eukaryotes have a nucleus and lastly, for D, only eukaryotes contain membrane-bound organelles. hope this helps :)
Both cell types undergo cell division by mitosis. Therefore, option (C) is correct.
What are eukaryotic and prokaryotic cells?A nucleus and other membrane-bound organelles are exclusively found in eukaryotic cells, which is the main distinction between prokaryotic and eukaryotic cells. Prokaryotes and eukaryotes, respectively, are made up of prokaryotic and eukaryotic cells. Eukaryotes often have several cells, but prokaryotes are invariably unicellular. Eukaryotic cells are also between 100 to 10,000 times bigger and more complicated than prokaryotic cells.
Prokaryotic DNA is kept in the cytoplasm, while DNA in eukaryotes is kept in the nucleus. Additionally, double-stranded chromosomes that are compressed by histones are where eukaryotic cells store their DNA. Prokaryotic organisms, on the other hand, only contain one basic circular chromosome and a variety of plasmids, which are tiny DNA rings. In comparison to prokaryotic cells, the DNA of eukaryotic cells contains a higher percentage of non-coding DNA and proportionately less coding DNA.
