It is basically a structure which helps segregate the chormosomes in to the daughter cells

Limiting factors will affect a specific species that lives in an area for example a<span>ll </span>living<span> things need food, water, shelter and space to survive if i built a dam on a river that would be supplying water to the forest to the wild animals this will make a shortage of water for the animals and they could die from this shortage </span>
In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy.
This relates to the speed at which an object should travel to "break" free of any gravitational pull.
Venus: 10.46 km/s
Mars: 5.027 km/s
Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
toxic enzymes that damage the host cell that are coded for in the viral genome
secretion of chemicals from the virus to the membrane of the host cell
replication of the viral genetic material within the host
lysis of the host to release new viruses
integrating into the host cell chromosomes
Answer:
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.
