The first organisms to appear in an area undergoing succession are known as the pioneer species. These organisms lead to a more biodiverse steady-state ecosystem.
Answer:
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3
Explanation:
In cats the allele for short hair is dominant over the allele for long hair. (SS or Ss for short hair; ss for long hair).
A short haired male and long haired female have kittens. Eight kittens have short hair and 3 have long hair.
For the parents to have been able to produce long haired offsprings, it means both parents possess one copy each of the recessive traits. Thus we have
Phenotype of parent: A short haired male and long haired female
Genotype of parents: Ss x ss
Genotype of offsprings: Ss ss
Expected ratio of short to long: 2 : 2 = 1 : 1
The actual ratio in this problem is Eight kittens have short hair and 3 have long hair: 8 : 3

Answer:
The paraphrase consists in saying with simpler words and with less technical words those obtained from a text. In this way, it facilitates its understanding, because the original information extracted is expressed in a simpler way.
The correct way to paraphrase is 2. Every organism must acquire and use energy to build new structures, repair old ones, and reproduce
Explanation:
That option is referring to nutrition, which is the process by which nutrients contained in food meet the needs of cells and allow the proper development of organs. For example, certain organs such as the liver, brain, heart and kidneys, in normal conditions account for 60-70% of total energy expenditure of the organism, to which we must add the energy used in the synthesis and in the new tissue formation
Answer:
C : 1953
Explanation:
The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science.
