Why does DNA form multiple origins of replication along the chromosome?
DNA forms multiple origins of replication along the chromosome to ensure that the entire DNA molecule can be replicated efficiently and accurately during cell division. Having multiple origins of replication allows for simultaneous replication of different sections of the DNA molecule, speeding up the process and ensuring that the genetic information is faithfully copied.
An efferent nerve takes an impulse towards the brain?
Efferent nerves carry signals away from the brain to muscles and glands, enabling movement and other bodily functions. A nerve impulse travels in one direction along these nerves, from the central nervous system to the periphery.
How are egg cells adapted to their functions?
Egg cells are adapted to their function of fertilization by having a large size to store nutrients for the developing embryo, a protective outer layer to prevent multiple sperm from fertilizing it, and containing organelles such as mitochondria to provide energy for cellular activities.
Why streptococcus is in chain form and staphylococcus in cluster form?
Streptococcus bacteria divide in only one plane, resulting in a chain formation, whereas staphylococci divide in multiple planes, leading to a cluster formation. This difference in cell division patterns determines the characteristic arrangements of these bacteria.
What are the ways to prevent algal bloom?
To prevent algal blooms, reduce nutrient runoff from agricultural and urban areas, properly manage wastewater treatment facilities to limit nutrient discharges, and avoid excessive fertilizer use. Implement buffer zones along water bodies to filter runoff, and promote sustainable land management practices to prevent nutrient enrichment of water bodies.
How does ovum prevent multiple penetrations of sperm cells along its periphery?
as soon as a single sperm fertilises the ovum a change of composition takes place in ovum's outer layer forming zona pellucida which prevents the penetration of other sperms.
Core and periphery model-India?

What is the closest town to the Sahara desert?
The Sahara Desert covers a huge area - almost the top 1/3rd of the African continent. There are a number of villages, towns and even cities located within the desert, but in most cases along the periphery
What moves cell parts along microtubule?
Motor proteins, such as kinesin and dynein, move cell parts along microtubules by utilizing energy from ATP hydrolysis to generate mechanical force. Kinesin generally moves cargo towards the cell periphery, while dynein moves cargo towards the cell center.
How people benefit from the dams along the Colorado River?
They prevent flooding and produce electricity.
What warm current moves west along the equator in the North Atlantic?
Gulf SteamA gyre current is a system of four currents completing a flow circuit around the periphery of an ocean basin. This gyre current would be called the North Atlantic gyre.
