Define atomic number and mass number – describe how they differ

Biology
1 answer:
larisa86 [58]2 years ago
3 0

Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

hope this helps have a great night❤️❤️❤️❤️

A large flock of endemic birds is discovered on a remote island. There appears to be two similar but different kinds of birds wi
den301095 [7]

Answer:

Option C

Explanation:

There are cases when two organism of different species mate to produce offspring but that offspring is unable to reproduce further.  Hence, such organisms do not belong to the same species. Thus, Option D is incorrect

However, when two organisms are able to reproduce viable offspring, they are said to be of the same species. Such organisms are also similar in looks.  

Hence, option C is correct

Answer:

C) specialists.

Explanation:

The finches of the Galapagos Islands would be considered specialists. This is because the finches have diversified in a way in which each species has uniquely evolved to perform a very specific task (eating a particular type of food). Moreover, this process is known as adaptive radiation, as a single lineage (the original finch) undergoes speciation events that eventually fill divergent ecological niches, creating many related species.

Sort the descriptions based on whether they are related to asexual reproduction or sexual reproduction
miss Akunina [59]

Answer:

Sexual Reproduction:

  1. Creates genetically unique offspring.
  2. Organism needs time to  reach adulthood and to reproduce.
  3. Requires the contribution of two parents.

Asexual Reproduction:

  1. Creates genetically identical offspring.
  2. Organism doesn't have to waste energy to find a mate.
  3. Requires the contribution of a single parent.

Explanation:

Sexual Reproduction:

  • Sexual reproduction involves the fusion of a male and female gamete. A gamete is a haploid cell that contains half of the chromosomes as in the parent cell. This process is called fertilization and it results in the formation of a zygote, a diploid cell that develops into an embryo and ultimately an individual.
  • Sexual reproduction involves two parents, each of which contributes one set of chromosomes (23) to the offspring.

Asexual Reproduction:

  • Asexual reproduction produces an exact copy of one single parent. Offspring produced through asexual reproduction do not possess genetic variation.
  • Asexual reproduction occurs through four processes:
  1. Binary fission
  2. Fragmentation
  3. Budding
  4. Parthenogenesis

Did Darwin first believe that each finch he found was a different species?
Neko [114]
No, Darwin did not believe that they were different species.

The differences in the finches proved his theory of evolution to be likely. The finches evolved based on traits that fit their environment. The different finches were the same species, however, their traits differed based on their environment.
