What is the role of microfilaments in cell division

Biology
2 answers:
lesya [120]3 years ago
5 0

Answer:

Micro-filaments are long thread-like strands which are made up of repeating units of the protein actin.  

They with other network filaments like microtubule and intermediate filaments form the cytoskeleton of cell and also participate in the process of cell division at different levels like cytokinesis and mitosis.

1. During M-phase- at metaphase, they form spindle fibres which attach to the kinetochore of chromosomes and pull apart the chromosomes during anaphase.

2. During cytokinesis- in animal cells, at anaphase, they form actin fibres which forms contractile ring inside of the cell membrane and constrict animal cell from all sides.

Thus, micro-filaments plays an important role during cell division.

Laying eggs belong to which category of energy use? Maintenance, waste production, movement, growth and reproduction
lapo4ka [179]

Answer:

I HOPE IT WILL HELP U

Explanation:

Majority of the people in the poorest regions of the tropics rely on poultry production as their major source of protein supply. However, poultry production is hindered by the harsh environmental conditions in this regions therefore, reducing the daily supply of protein. It is believed that understanding heat stress in birds by paying detail attention to the sources of heat generation in a poultry house can help manage the heat stress situation in this region. This text reviews the internal climatic conditions of the poultry houses, how the birds respond to them, and their implications for heat management in poultry production. Thus, it provides pertinent information for guidance on parameters for open poultry houses architectural design that ensures optimum climatic conditions that will alleviate heat stress problem in poultry production in hot and humid climate.

A neutron star collapses into a black hole because of the force of (fusion,gravity)
stealth61 [152]
Gravity

Neutron stars are the most extreme and fascinating objects known to exist in our universe: Such a star has a mass that is up to twice that of the sun but a radius of only a dozen kilometers: hence it has an enormous density, thousands of billions of times that of the densest element on Earth. An important property of neutron stars, distinguishing them from normal stars, is that their mass cannot grow without bound. Indeed, if a nonrotating star increases its mass, also its density will increase. Normally this will lead to a new equilibrium and the star can live stably in this state for thousands of years. This process, however, cannot repeat indefinitely and the accreting star will reach a mass above which no physical pressure will prevent it from collapsing to a black hole. The critical mass when this happens is called the "maximum mass" and represents an upper limit to the mass that a nonrotating neutron star can be.

However, once the maximum mass is reached, the star also has an alternative to the collapse: it can rotate. A rotating star, in fact, can support a mass larger than if it was nonrotating, simply because the additional centrifugal force can help balance the gravitational force. Also in this case, however, the star cannot be arbitrarily massive because an increase in mass must be accompanied by an increase in the rotation and there is a limit to how fast a star can rotate before breaking apart. Hence, for any neutron star, there is an absolute maximum mass and is given by the largest mass of the fastest-spinning model.

Temperature is a way to measure the ___________ energy of particles of matter.
Fed [463]

Answer:

Kinetic

Explanation:

The average kinetic energy of the particles in a material is measured by temperature. The overall kinetic energy of the particles in a material is measured by thermal energy. The higher the particle mobility, the higher the temperature and thermal energy of a material.

The function of pulmonary ventilation is to ___________.
lara31 [8.8K]

Answer:

The function of pulmonary ventilation is to b. maintain adequate alveolar ventilation.

Explanation:

<em>Pulmonary ventilation refers to the movement of air into and out of the lungs, so its main function is to maintain adequate alveolar ventilation.</em> The air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere. In the lungs, Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. That's how the oxygen gets into the bloodstream.
