The Universe is defined to be the sum total of everything that we know about: stars, galaxies, clusters, superclusters, voids, etc.
Cosmology is the study of the structure and evolution of the Universe.
It is a subject of great current interest, as the Hubble Space Telescope and other new instruments have recently helped astronomers shed light on many important questions.
There have been many theories about the Universe, but they generally all share one fundamental postulate, the cosmological principle, which has two parts. First, the Universe must be isotropic (the same in every direction).
For example, the Hubble deep field images, extending 12 Gly away, for two completely different directions, are remarkably similar:
Answer:
IgE
Explanation:
Immunoglobulins can be described as antibodies that are found in blood and other bodily fluids of humans and other vertebrate animals. And their major function is that they help identify and destroy foreign substances such as microbes such as bacteria and protozoan parasites.
They are known to be produced by produced by plasma cells (white blood cells).
Immunoglobulins are classified into five categories: IgA, IgD, IgE, IgG and IgM. And are distinguished by the type of heavy chain they contain. IgG molecules possess heavy chains known as γ-chains; IgMs have μ-chains; IgAs have α-chains; IgEs have ε-chains; and IgDs have δ-chains.
In this case, IgE is the immunoglobulin that attach to and sensitize mast cells and basophils.
Answer:
you could be strict or just have consequenes like taking stuff away
Explanation:
Answer:
Bacteria has prokaryotic cells i. e. no true nucleus or membrane around the nucleus. They lack mitochondria, ribosome, lysosomes, endoplasmic reticulum, golgi bodies and cell wall.
Explanation:
Prokaryotes are the organisms which have no true nucleus while eukaryotes have true nucleus. True nucleus means that the membrane is present around the nucleus. Many organelles are also absent in prokaryotic cell which are present in eukaryotic cells.
Answer:
The answer is down below.
Explanation:
Estuaries
-More than 80 percent of all fish and shellfish species use estuaries as primary habitat or as a spawning or nursery ground.
-Estuaries are often called the “nurseries of the sea”.
-Estuaries and their surrounding wetlands are bodies of water usually found where rivers meet the sea.
Abiotic factors
In an estuarine ecosystem, these factors are light, oxygen, water, nutrients, temperature, salinity, and space. So just divide these into three.
Biotic factors
These include plants and animals such as shrimp, fish, and oysters
