Evolution is the change in heritable traits of biological populations over successive generations.

What is evolution of life?

  • Evolution has produced the variety of life that exists on Earth today. Since life first emerged on Earth between 3.5 and 4 billion years ago, it has continued to develop.
  • At initially, there were just single-celled, primitive species on Earth.
  • The first multicellular organisms appeared much later, and as a result, the diversity of life on Earth significantly increased.
  • Darwin put out a substantial amount of evidence to back up his idea of evolution by natural selection.
  • Evolution is the gradual alteration of a living thing's traits over time. Natural selection is the process of evolution.
  • Through their DNA, organisms transmit their traits from one generation to the next.

If there are 32 sister chromatids in a normal somatic cell, what is the haploid number for that cell?
malfutka [58]

Answer:

The answer is 16.

Explanation:

Somatic cells include all the cells in the body except for the reproductive cells. Haploid cells are used to represent the reproductive cells which have half the chromosome as the somatic cells. So if there are 32 sister chromatids in a somatic cell, which means there are 16 chromosomes, then the haploid number for it is 16 chromatids. I hope this answer helps.

Why is water essential to life on a chemical level?
babymother [125]
Well Water is essential to life for a number of reasons. It is a useful solvent that exists as a liquid at the ideal range of temperatures for life as we know it on Earth, behaving as a perfect medium across which biochemical reactions can occur. Your cells transport resources across the spaces within and between them facilitated by this medium, just as your blood serves as the ideal medium for transporting oxygen-carrying corpuscles and a rich soup of nutrients, hormones, and even waste products being sent for filtration. The very structure of your tissues is reliant upon water content; consider the difference between a fresh loaf of bread and a stale (dry)one that can be crumbled between the fingers. Plant cells, just like animals cells, require hydration to function, too. In fact, right down to unicellular life forms, life as we know it on this planet relies upon water existing as a liquid in order to function on a <span>biochemical level. I hope that helps you.</span>

Which of the following processes can viruses carry out? They can manufacture their own ATP, proteins, and nucleic acids. They ca
storchak [24]

Answer:

They can use the host cell to copy themselves and make viral proteins

Explanation:

Viruses are organisms that are incapable of replicating on their own without infecting a living host. They use the host's ability to transcribe, translate and replicate to replicate themselves and translate their genetic material into proteins. The infection cycle represents their reproductive cycle.

Viruses infect their host cell by initially binding to specific receptors on the host's cell membrane. Then, they enter the host cell and incorporate their genetic material into the host's genome. They, then, use the replicational ability of their host to produce many virions and make proteins.
