because babies need different types of cells to do different jobs as the fertisiled egg starts to divide each cell specialises to from a part of a body
As the fertilized egg begins to divide, each cell becomes specialized to come from a portion of the body because kids need various types of cells to perform various tasks.
What is the role of cell differentiation in infant?A multicellular creature requires differentiated cells because they can carry out specialized tasks for the body.
Specialization, though, has a price. The trade-off is that differentiated cells frequently lose their capacity to proliferate.
When discrete tissue layers first emerge during a process known as gastrulation in vertebrates, differentiation starts.
Cell differentiation is a crucial process through which a single cell gradually evolves, enabling development that leads to the formation of diverse organs and tissues.
Therefore, for growth and development of baby cell differentiation is important.

Your friend Olivia has a blemish on her shoulder that she can't easily see herself, so she asks you to check it out for her to help her decide if she should see her doctor. What are at least three things you would look for to help you advise her? (Remember: ABCDE!)
Answer:
Explanation:
There are a couple of things you can look for when analyzing your friend's blemish to determine whether she should see a doctor or not. Three of these signs are
Discoloration or texture on the blemish.The blemish is itchy or irritated.The blemish is bleeding
All three of these are signs that Olivia should see a doctor/dermatologist as soon as she can. This is because all of these point to skin cancer. A regular blemish is a single color and is imbedded within the skin. It does not appear textured or out of the skin, or even two or three different colors. Blemishes also are not itchy or bleed. Therefore, any of these signs would be a cause for concern.

3. What would happen if all of the top-level consumers in the reef ecosystem died out?
Answer: Coral reefs provide protection against flooding and the erosion of coastlines. With them gone, there will be rapid erosion of coastlines and many small island countries might even vanish from the world map. There may be many more serious repercussions that we are unable to perceive at this moment.
Answer:
The reef would die.

4. In this investigation oxygen production was used to measure the light reaction. What are
two additional products that could be measured? What purpose do they serve in the light-
independent (dark) reaction?
Answer:
Photosynthesis is the process by which green plants absorb light energy from the sun with the assistance of water and carbon dioxide, and transform it into chemical energy to make (synthesize) carbohydrate (specifically glucose) and oxygen.
The "light-independent" or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle. Since these processes can only happen in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can only happen in green plants!
The first overall principle of photosynthesis is that the light energy from the sun is transformed into chemical energy and stored in the bonds of glucose (the sugar carbohydrate) for later use by the plant and/or organism that eats the plant.
The second overall principle of photosynthesis is that carbon, oxygen, and hydrogen atoms are taken from carbon dioxide and water molecules and are broken up and rearranged into new substances: carbohydrate (specifically glucose) and oxygen gas (so we can breathe, whew!). This reaction represents the transfer of matter: carbon dioxide from the atmosphere, water from the soil or atmosphere, into sugar in the plant and oxygen back into the atmosphere.
Light-Dependent Reactions
The first part of the process happens in the thylakoids of the chloroplasts and are the "light-dependent" reactions: The photosystems I and II absorb the photons from the sunlight and process them through the membranes of the thylakoids simultaneously. The photons excite electrons in the chlorphyll which then move through the electron transport chain and causes NADP- to combine with H+ forming NADPH. At the same time, ADP (adenosine diphosphate) has come from the dark reaction and a third phosphate chain is bonded forming ATP (adenosine triphosphate) to feed the Calvin Cycle next. Remember that ATP is the important source of all cellular energy.
We now believe that all the oxygen released in photosynthesis comes from the water molecules and all oxygen atoms that form the carbohydrates come from the carbon dioxide molecules. So, in other words during the light-dependent reaction a water molecule is broken down producing two H+ ions and half an oxygen molecule. We get the rest of the oxygen molecule when another water molecule is broken down.
Dark Reactions
Dark reactions are also known as the Calvin Cycle, the Calvin-Benson cycle, and light-independent reactions. The point is that they do not require sunlight to complete their process.
After ATP is formed in the first part of photosynthesis, for living things to grow, reproduce and repair themselves, the inorganic form of CO2 must be transformed into carbohydrate. This happens during the Calvin Cycle in the stroma (the fluid filled interior of the chloroplast). ATP and NADPH combine with CO2 and water to make the end product of glucose. The ADP and NADPH+ are recycled to the light-dependent side to start the process over.
Remember that during hours of darkness, plants cannot perform photosynthesis so they do cellular respiration in the mitochondria just as all living organisms do.

A city is located in an area that has experienced 7.5-magnitude earthquakes in the past. The city is considering building a new skyscraper.
Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude. Then suggest a way to minimize the effects of future earthquakes on the skyscraper.
Answer:
The residents should expect collapsing parts of the building, or even the building itself would collapse if the building cannot hold/not sturdy enough for earthquakes ranging around 7.0m to 7.9m. If the building is built by hills or rocky land, expect landslides to be happening. A way effects of future earthquakes can be minimized is that the building should be constructed with sturdy material (such as steel) so that it can withstand most of the force of a 7.0-7.9m earthquake.

Answer:
Ptolemy
Explanation:
Ptolemy is the earliest earliest astronomer and mathematician in the list who lived and worked in the second century AD. Nothing is known about his personal life but his scientific work is well known.
He made his observations using naked eyes. In his opinion, the Universe is ''a set of nested, transparent spheres, with Earth in the center.''(Khan Academy). His argument was that the Moon, Mercury, Venus, and the Sun were all revolving around around Earth.
Although Ptolemy made significant contributions in Astronomy but he was wrong in positing that the earth did not move at all. This is inconsistent with our present day knowledge about the celestial bodies. Also, his work missed out other planets that were yet to be discovered then such as Uranus, Neptune, Pluto etc.
