n _____ muscle, some calcium needed for contraction is from the extracellular fluid.
Answers
Some of the calcium required for contraction in cardiac and visceral smooth muscle comes from extracellular fluid.
Normal functioning necessitates the presence of calcium, oxygen, and adrenaline, all of which might modify the contraction's power. This simulation looks at the variables that affect cardiac muscle contraction. The "data" you will gather was captured during recordings of the test circumstances you will encounter in this simulation, therefore it is "actual" data. Visceral, or smooth, muscle is present in blood arteries as well as internal organs like the stomach and intestines. It is known as a smooth muscle because, in contrast to skeletal or cardiac muscle, it .

What is Emigration
Emigration is the movement of organisms out of their natural habitat into a new habitat mosty insearch of food or new habitat. and can be occasioned by natural or man made disasters.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answers
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

based on the information that you found on mesosaurus, how do you think this animal might have gotten distributed in this pattern?
Answers
Mesosaurus got distributed in this pattern because of the extinction of Pangea 250 million years ago.
The genus of extinct aquatic animals known as Mesosaurus, which means middle lizard, lived in the southern hemisphere during the early Permian period. Mesosaurus fossils can be found in Africa and South America. They were separated during the 250 million-year breakup of Pangea. Strong evidence for the existence of Pangea is provided by the identical fossils found in both locations.
After early tetrapods arrived on land in the Late Devonian or later in the Paleozoic, Mesosaurus was one of the first known reptiles to return to the water. It had webbed feet, a streamlined body, and a long tail that may have supported a fin. It was about 3.3 feet long. It probably used its flexible tail and long hind legs to move through the water.

Explain the endosymbiotic theory and explain whether it is true with details.
Answers
Explanation:
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
Evidence for this is based on the following:
Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane. Mitochondria and chloroplasts have their own DNA that is circular, not linear. Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S. Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
