What contain spicules and prominences?
Spicules are small, needle-like structures found in sponges, while prominences refer to the large, arching structures seen on the Sun's surface.
How the microtubules of the cell cytoskeleton form?
Small unit proteins polymerise when calcium ions are present.
How do you calculate readings of sextant?
first find out least count of main circular scale in degrees,then divide least count of main scale by total divisions on cylindrical scale(this cylindrical scale works as vernier scale for fist one,its least count will be in minutes) then further divide least count of cylindrical scale by total divisions of small vernier scale which touches it,(this small scale works as vernier scale for cylindrical scale and its least count will be in seconds).
What are small cavities in the ovary?
Small cavities in the ovary are known as ovarian follicles. These structures contain developing eggs and are essential for ovulation and fertility. Each month, one follicle will mature and release an egg during the menstrual cycle.
Does human sperm contain cilia?
No, human sperm cells do not contain cilia. Cilia are small, hair-like structures that can be found on certain cells. However, sperm cells have a flagellum, which is a long tail-like structure that allows them to swim.
What are small dark cylindrical structures that are made of microtubules and located just outside of the nucleus?
Those are likely centrioles, which play a crucial role in cell division by assisting in organizing the microtubules that form the spindle apparatus. This structure is essential for proper chromosome segregation during mitosis.
These structures are small cylinders composed of triplet microtubules and act as basal bodies?
Centriole
What are centrioles composed of?
Centrioles are composed of microtubules arranged in a specific pattern, typically in a cylindrical shape. They play a key role in organizing the microtubules of the cytoskeleton and are essential for cell division.
What color is a centrioles?
Centrioles are typically colorless and do not have a distinct color. They are small, cylindrical organelles found in animal cells, usually appearing as pairs near the nucleus. Their primary function is to organize microtubules during cell division.
What is villi and what important structures do they contain?
these are in the ileum wall in the small intestine and they are rsponsible for absorption of nutrients into the bloodstream
What contain spicules and prominences?
Spicules are small, needle-like structures found in sponges, while prominences refer to the large, arching structures seen on the Sun's surface.
What small structures found in cells that contain chemicals which help digesy food and worn out cell parts?
This organelle is called the lysosome.
What structures do spindles originate?
Spindles originate from the centrosomes, which are small organelles found near the cell nucleus. The centrosomes organize microtubules to form the spindle apparatus during cell division, ensuring proper chromosome segregation.
How the microtubules of the cell cytoskeleton form?
Small unit proteins polymerise when calcium ions are present.
What is the small dark cylindrical structure just outside of the nucleus called?
Centrioles
What does a dowel look like?
A dowel is a small solid piece of cylindrical wood.
What are the small structures in the?
the tiny structures within the small intestine that absorb nutrients are called Villi
