Choose the accurate statement(s) regarding the types of fibrous joints.
a) The attachment of a tooth to Its socket is Classified as a syndesmoses Joint.
b) In syndesmoses joints, the fibers are longer and the attached bones ate mote movable.
c) In gomphoses joints. two bones are linked by carriage
d) In sutures and gomphoses, the fibers are very short and a Sow for little or no movement
e) Sutures are immobile or only slightly mobile, fibrous joints that closely bind the bones of the skull to each other.
Answer:
The correct answer is - B, D, and E.
Explanation:
Syndesmoses joints are the joints that are fibrous join two bones with strong ligaments or membranes. In these joints are contiguous bony surfaces are united by an interosseous ligament. These are the joints that are slightly movable and longer.
Sutures and gomphosis are syndesmosis joints that are short and show very little or no movements fibrous joints that closely bind the bones of the skull to each other.
Persistence length for a cytoskeletal filament is the minimum filament length at which random thermal fluctuations are likely to cause it to bend. Which of the following comparisons are true, considering the persistence lengths of (a) an actin filament, (b) a bundle of cross-linked actin filaments, and (c) a microtubule
The provided question is incomplete as the group of choices were not given, however, the choices as follows:
A. (a > b) and (a > c)
B. (a > b) and (a < c)
C. (a < b) and (a > c)
D. (a < b) and (a < c)
E. (a > b) and (b > c)
Answer:
The correct answer is - D. (a < b) and (a < c)
Explanation:
The persistent length of actin filaments, a bundle of cross-linked actin filaments and microtubules can be compared on their typical persistent length.
The persistent length of actin filaments is 15 µm. And due to the crosslink with one another to make a bundle their length reduced As the actin filaments cross-link each other their persistent length will be reduced. however, it is still longer than single actin filament around 20 nm.
The persistent length of microtubules is 6mm.
So b > a, a < b and a < c.
So fourth option a < c and b > a is the correct answer.

short note on occurrence of water in different source and state
Answer:
Water circulates in nature through a continuous and permanent process called the hydrological cycle or the water cycle. In this process the physical and biological elements of nature intervene, atmosphere, rain, water from lakes, rivers and seas, soil and vegetation. Water is in several states: solid state, which is ice. Liquid state, includes groundwater, which is found in the deep layers of the soil, and surface water, which includes innumerable rivers, and a gaseous state, which is found in air and clouds.
Explanation:
Water covers 71% of the earth's surface. The water cycle comprises three phases: Evaporation, filling the atmosphere with large amounts of water vapor (gaseous state). Condensation, forming water droplets in the form of a cloud or mist. Precipitation: the water vapor that is the clouds cools and precipitates in the form of rain, hail or snow. When the rain falls, some of the water is retained in the dense foliage and branches of the trees. Another seeps into the ground, forming the layers of underground water and the other part drains superficially forming streams, rivers or increasing their flow. All water, through evaporation, can change back to the gaseous state, restarting the water cycle. On our planet, water is located mainly in the oceans where 96.5% of total water is concentrated, glaciers and polar caps have 1.74%, underground deposits in (aquifers), and continental glaciers represent the 1.72% and the remaining 0.04% is distributed in decreasing order between lakes, soil moisture, atmosphere, reservoirs, rivers and living beings. Water is found in nature in three different forms or states in: solid state, such as ice, hail or snow, liquid state, such as the water we consume and the water of the seas, rivers and lakes and in the gaseous, when it forms clouds or steam that comes out of boiling water.

Conclusion:
Use your data to answer the following questions. Use complete sentences, and be as detailed as possible.
How did scientists discover that all living things are made of cells?
Around 1850, Virchow saw cells dividing and added that living cells arise only from other living cells. These ideas led to cell theory, which states that all organisms are made of cells, all life functions occur in cells, and all cells come from other cells.
How did Pasteur’s experiment with the flasks help disprove the idea that living things could just appear or come from nonliving things like water and air?
The end of the revolutionary period of the theory of abiogenesis and biogenesis was after the appearance of Louis Pasteur (1822-1895), a chemist who was very interested in chemical changes that occurred during the fermentation process of wine.
Why are nutrients needed for living things? Describe the difference between living and nonliving things.
all living things need water, and some source of food. The difference between a living and non-living thing is that one need water and other nutrients to keep it alive whereas non living things do not.
