We all start out as one cell. cell differentiation, or specialization, occurs when early embryo cells switch off certain unneeded genes.
Cell differentiation is the process in which the cell divides and changes their functional or phenotypical type. They are specialized and differentiated to perform a particular function. For example, epithelial cells, nerve cells, smooth muscle cells.
The cells in the embryonic stage are pluripotent and can divide to form the whole body. They are not specialized and have the ability to differentiate into any cell of the body.
In embryonic stage, some of the genes are switched off in certain cells which enable them to differentiate into a particular type of cell.

2. (a) Identify the range diagram above in which most of the species population is found. Explain why this is the case:
________________________________________________
(b). Describe the greatest constraints on an organism's growth and reproduction within this range: ________________________________________
a) Most individuals are found within the optimum range, which is where there is a higher degree of preferred niche. b) constraints are competition for resources and female access, and preferred niche running out faster.
What is the tolerance range?
The tolerance range refers to the limits between which a species can live and reproduce. These limits depend on environmental factors, which might be biotic or abiotic.
The environmental factors that influence a species' survival are the limiting factors. These are, for instance,
temperature, pH, radiation, salinityIn an environment, and concerning a particular species, we can identify three different zones or ranges,
Optimum ⇒ this range has the best conditions for individuals' survival and reproduction. The largest populations live withing this range.Physiological stress ⇒ this area does not have the best conditions. Only a few individuals can survive here, and populations are small. Intolerance ⇒ In this area there are bad conditions for individuals to survive. They can not live in this ranges. No population is found here.In the exposed example, we have the relationship between number of individuals and niche availability. The limiting factor here is niche availability.
2. (a) Identify the range diagram above in which most of the species population is found. Explain why this is the case:
Most individuals are found within the optimum range, which is where there is a higher degree of preferred niche. Preferred niche is where they can hide, feed, and reproduce.
(b). Describe the greatest constraints on an organism's growth and reproduction within this range
As we can see most individuals and the largest populations are inhabiting the same range. What does it mean?
It means
Greater competition for resources and mating events. Individuals will compete for food and shelter. Males will compete for female access.The higher the number of individuals living in the same range, the faster resources will run out. This means that in a relatively short time there will not be available preferred niches for these fishes.

Platelet transfusion is to be administered to a child with acute lymphocytic leukemia. which step would the nurse do first?
If platelet transfusion is to be administered to a child with acute lymphocytic leukemia then, the nurse would first : administer the platelets rapidly through the intravenous (IV) line.
Platelets are delicate and should be infused as soon as the child is able to tolerate it or as quickly as the young patient's cardiovascular condition will allow, ideally within an hour. A severe reaction is less likely because the infusion contains little in the way of white blood cells (WBCs) and red blood cells (RBCs).
What does platelet transfusion actually entail?
In patients with low platelet counts or functional platelet disorders, platelet transfusion is a life-saving procedure used to stop ongoing bleeding or stop potential bleeding. As not all low platelet levels call for a transfusion, there are minimum thresholds at which platelets are given to these patients. Due to the time and effort required to precisely prepare, process, and transfuse platelets while maintaining a certain quality, platelets are a scarce resource.

Petri dishes should? always be labeled on the lid. be left open while incoulating. be stored with the lid on top. always be stored inverted.
Petri dishes should always be stored inverted.
In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.
Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.

The Continental Lithosphere is the least dense because of its relatively low density. As a result, the Lithosphere is the most rigid part of the mantle, while the asthenosphere is the somewhat more fluid portion.
Although, the Continental Lithosphere is composed of an approximately 20 to 35-mile layer of the light granitic crust underlain by a 60 to 80-mile layer of the heavy mantle. Another possible option is the Oceanic Lithosphere, but it is 4 miles thicker than Continental Lithosphere.

How do you think the reactivity of aluminium compares to the reactivity of other metals?
In a complex, a more reactive metal will replace a less reactive metal. Aluminum replaces iron in iron(III) oxide because it is more reactive than iron. Iron is decreased when aluminum eliminates oxygen from iron(III) oxide.
Despite being such a reactive metal, aluminum does not react well with airborne oxygen. Because it has previously reacted, the aluminum oxide has developed into a thin, strongly bound layer that shields the aluminum foil from additional attacks, which is why it does not react.
The metal aluminum is quite reactive. It easily generates a layer of aluminum oxide on its surface when oxygen from the air reacts with it. This coating of aluminum oxide is exceedingly thick and prevents air from entering the metal to cause further reactions.
Aluminum is a reactive metal that is challenging to separate from aluminum oxide, its source (Al2O3). The fact that aluminum oxidizes quickly and that its oxide is an exceptionally stable molecule that, unlike rust on iron, does not flake off makes aluminum one of the hardest metals on Earth to purify.

These signals SIGTERM, as well as SIGQUIT,as well as SIGQUIT, are used to end processes. In this instance, we particularly ask that it be completed. When we employ the kill command, the default signal is SIGTERM. All signals automatically end the procedure as its default response. SIGQUIT, though, also creates a core dump just before terminating.

The effects of biota in soil formation are closely related to, and hard to distinguish from, the effects of climate.
Even within a backyard, there are differences in the type of soil that exists. They differ in origin and development process. Different types of soils are shaped by the interaction of five key factors: climate, organisms, topography (landscape), matrix and time. The rate of chemical reactions is affected by temperature and humidity, which affects weather and the rate at which dead animals decompose. Soil develops faster in warmer and more humid regions than in cold or dry regions. One of the most important climatic variables for soil formation is precipitation.

Sodium reacts explosively with oxygen while iron does not. Which of the following is MOST responsible
for the differences in the chemical reactivity of sodium and iron?
The reason why sodium reacts explosively with oxygen while iron does not is the number of electrons in the outer electron shell.
What is reaction?In a chemical reaction, we have the combination of two substances to form a new substance. Now we have to recall that metals do have an order of reactivity. The metals that are more reactive are found at the top of the activity series and the metals that are less reactive are found below in the series. In this case, sodium is more reactive and is found higher in the series while iron is found lower in the series.
Recall that the activity series is arranged in the order in which the metals are able to loose electrons. The metals that loose electrons more easily occupy the u[per parts of the activity series of metals. Iron lies at the middle position but far below sodium in the activity series of metals.
