time window ensures that the cervix close, postpartum bleeding stop,

Answer:
450 years all in all but it'd take about 1000 years in a landfill
Explanation:
Answer:
The correct option is <u>4. They are specialized.</u>
Explanation:
All cells in our body originate from the stem cells. The stem cells keep dividing and become specialized. Each specialized cell in the body performs a specific function for which it is made. Also, the shape of some cells is changed so that they have a shape which allow them to perform their functions. For example, the cells in our muscles are termed as myocytes. There are three different kinds of myocytes, each with different shapes which allows them to function properly.
Answer: The sequence of events of avocado seed germination includes:
Water absorption --> enzyme activation --> radicle emerges --> lengthening of the hypocotyl --> growth of epicotyl and plumule development --> shrinking of the cotyledons.
Explanation:
Germination is defined as all the changes that occurs when a seed embryo resumes it's growth and development to become an independent seedling. Seeds usually germinate in two ways:
--> EPIGEAL germination: in this type of germination, the hypocotyl grows rapidly and elongates, carrying the cotyledon above the soil.The AVOCADO seed is a typical example of a dicotyledonous plant.
The sequence of events of avocado seed germination starts by imbibition which is the rapid in take or absorption of water by the seed through osmosis. Hydration of the embryo activates the enzymes in it which converts insoluble stored food materials into soluble forms. The testa splits and the radicle emerges first. It grows downwards as the primary root from which root hairs and branch roots arise( to form a tap root system). Next, the hypocotyl lengthens, pushes its way up through the soil carrying with it the cotyledons and the plumule. The cotyledons turn green on exposure to sunlight and start to photosynthesize. The epicotyl then grows and the plumule develops into a green shoot. By the time the first foliage leaves grow and begin to photosynthesize, the cotyledons shrink and drop off.
Answer: cytosol
Explanation:
Ribosomes are special because they are found in both prokaryotes and eukaryotes. While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol.
