The first reaction of the body to a cut is to restore the continuity ?
Explanation:
First,blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.The platelets then release chemicals called Cytokines into your blood stream.Cytokines attract the attention of certain cells to start healing your cut.
When the skin injured,our body sets into motion an automatic series of events,often reffered to as the " cascade of healing",in order to repair the injured tissues.The cascade of healing is divided into four overlapping phases:Hemostasis,Inflammatory,Poliferative,and Maturation.

Most of the world's iron ore, including that found in northern Minnesota, formed during the middle Precambrian period, ranging in age from 1.8 to 2.5 billion years old. They are composed of alternating layers of iron-rich material, most often magnetite or hematite, and silica. These iron oxide minerals formed on the ocean floor, creating the banded iron deposits you see here. What was the source of the oxygen that helped to produce these deposits?
A) The oxygen that was released into the atmosphere as a by-product of photosynthesis caused iron deposits to oxidize creating the iron oxide minerals.
B) Photosynthetic organisms making oxygen as a by-product of photosynthesis and the oxygen reacted with the iron dissolved in seawater to form iron oxide minerals.
C) The decomposition of carbon-based life forms in the oceans released oxygen and carbon dioxide. These gases reacted with the iron deposits forming the minerals mentioned.
D) In Earth's early biosphere, there were not organisms that underwent aerobic cellular respiration and an excess of oxygen built up in the atmosphere. This oxygen reacted with iron deposits to form iron oxide minerals.
Answer:
b
Explanation:
Answer:
) Photosynthetic organisms making oxygen as a by-product of photosynthesis and the oxygen reacted with the iron dissolved in seawater to form iron oxide minerals.
Explanation:
the energy required to lift an object is supplied by atp derived from the breakdown of molecules of
ATP is derived from the breakdown of molecules of glucose. Glycolysis is
the metabolic reaction which converts glucose into ATP.
The energy in glucose has to be converted to a usable form by the cells
which is why it is always converted to ATP( Adenosine triphosphate). The
energy supplied by ATP is then used to perform various activities in the
body.
Glucose is a type of carbohydrate which is a means of energy in organisms.
The explanations given validates ATP has been derived from the
breakdown of molecules of glucose.

Explanation:
the 5 physical factors that scientists use to develop ocean and seafloor
zones are
1
2
3
4
5
Answer:
1. Light penetration
2. Distance from shore
3. Depth of water
4. Temperature
5. Amount of nutrients/salt
Explanation:
Oceanographers use various methods to determine vertical and horizontal zones in the ocean. First and foremost are the distance from the land and the depth of the water. These contribute to the other factors, such as temperature and light penetration. They also measure how much salt or nutrients are available at that zone, which plays a role in how much life is discovered in the location.
The photic and mesopelagic zones are mainly grouped by light penetration, while mesopelagic, abyssopelagic, hadalpelagic, benthic, and bathyal zone are categorized by depth and temperature. When looking at the pelagic zone, the neritic and the oceanic sections are differentiated by the distance from the land.
The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide

Stem cells can be developed into a required tissue because of their ability of cellular DIFFERENTIATION. These cells can develop specialized cells.
Stem cells are cells that can develop into specialized types of cells in order to perform specific functions.
The process of cellular differentiation from stem cells involves differential gene expression patterns, a cellular process that leads to the development of distinct types of cells.
For example, hematopoietic stem cells express specific genes (e.g., the hemoglobin gene) in order to differentiate into mature red blood cells that function to trasnport oxygen to all body cells.

a signal molecule which can bind to an enzyme and shut down its activity by altering the shape of the enzyme.
Answer:
Enzyme inhibitor
Explanation:
An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalysis of reactions and decreasing the amount of product produced by a reaction.
