Why did scientists eventually choose to support darwin's ideas about natural selection as a mechanism behind evolution rather th

an continue to support lamarck's ideas about how evolution occurred? natural selection appeared to happen somewhat more often than inheritance of acquired characteristics. natural selection became popular because it was more controversial than lamarck's ideas. natural selection was a new idea and gave them something different to investigate. natural selection provided a better explanation for what they observed in the natural world?

With the endosymbiotic hypothesis in mind, what structure within modern-day chloroplasts is likely derived from the cytoplasm of
Liono4ka [1.6K]

The chloroplasts had inner membrane

Explanation:

The primitive photoautotrophs utilized hydrogen sulphide as the electron donor to perform photosynthesis for energy production.  

Later upon understanding the endosymbiotic relationship of cyanobacteria which resided in the mitochondria of a eukaryotic host cell, the use of chloroplasts for photosynthesis was understood.  

Generations after generations led to the development of chloroplasts by the cyanobacteria due to this symbiotic relationships which developed into the chloroplasts.

The unique presence of the inner membrane and its components like the stroma, thyllakoids helped the organism to utilize water as the electron donor for photosynthesis like the present day eukaryotes. This is the main reason why cyanobacteria is considered as the ancestor for eukaryotes.

In certain bacteria, an oval shape (O) is dominant over round (o) and thick cell walls (T) are dominant over thin (t). Draw on a
seropon [69]

Answer:

Consider the heterozygous oval, thick cell walled bacteria to have the alleles OoTT and the thin cell walled bacteria to have alleles oott. Results will be 50% oval, thick walled bacteria and 50% round, thick walled bacteria. This will be the F1 progeny.

When the oval, thick walled bacteria from the F1 progeny is cross bred with round, thick walled bacteria then 25 percent of the bacteria will be heterozygous oval, thick walled. 25 percent will be heterozygous oval and heterozygous thick walled. 25 percent will be round and thick walled. 25 percent will be round and thin walled.

A species of mud snail was studied for five years. During this time, scientists observed the season in which they mated, the num
sergij07 [2.7K]

The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
