Protists use all of the following methods to obtain energy except A. photosynthesis/ B. ingesting food/ C. converting atmospheric nitrogen/ D. absorbing food.

Answers

Protists consist of various types of organisms. They can either be autotrophs or heterotrophs. Autotrophs meaning, they can produce their own source of energy through the process of photosynthesis. Heterotrophs, when they obtain their energy through ingestion or absorption from other sources. So in the given question, the method of energy that protists do not do is option C. converting atmospheric nitrogen.

Algae, which are protists, can obtain energy through photosynthesis. Protists which primarily obtain food in heterotrophic methods such as ingesting and absorbing for nutrition. However, protists cannot obtain food through nitrogen fixation since all nitrogen fixers are prokaryotic and protists are eukaryotic organisms.

Two species of flies, Drosophila melanogaster and Drosophila simulans, can mate. They usually do not mate, however, even if they are kept together in a laboratory. Males court the females of both species, but the females prefer to mate with males of their own species. Which isolating mechanism does this describe?A.)behavioral
B.)temporal
C.)geographical
D.)anatomical

Answers

A reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

Reproductive isolation refers to the mechanisms that prevent a species from mating with others, which have fundamental importance from an evolutionary point of view.

These barriers to fertilization can be divided into:

prezygotic isolation barriers, which prevent the fertilization of the egg
postzygotic isolation barriers, which prevent the generation of fertile offspring.

The most important prezygotic isolation barriers include, among others, habitat isolation, behavioral isolation, mechanical isolation, etc.

Behavioral isolation mechanisms are characterized by mating rituals (for example, the songs of males in certain bird species), which are capable of generating reproductive barriers.

In conclusion, a reproductive isolation mechanism in which females prefer to mate with males of their own species is a BEHAVIORAL mechanism.

The isolating mechanism involved is the behavioral change (A).

Further Explanation:

Isolating mechanism are those characteristics of the species that prevents them to reproduce with other members of the species.

There are various types of isolating mechanism:

1. Behavioral- Reproductive isolation that arises due to the behavior of the individual during their mating period.

2. Temporal- The species breeds at different time or they may have different breeding season, therefore this can lead to reproductive isolation.

3. Geographical- The isolation of species because they occupies different habitats.

4. Anatomical- Isolation that arises due to different internal structure of the species.

Example of isolating mechanism - when two species of flies, Drosophila melanogaster and Drosophila simulans, can mate however they usually do not mate. But even though they are kept with each other in any lab, males court the females of both species but the females prefers to mate with males that belongs to the same species.This example shows the behavioral isolation.

What might be an advantage of having more than one codon for the same amino acid?

Answers

There is no chance to change the amino acid sequence if any change occurs in the DNA or RNA sequence is an advantage of having more than one codon for the same amino acid.

What is genetic code?

Genetic code is the information of the gene which codes into the amino acid which makes the particular protein.

DNA has information that is passed to the RNA by the process of transcription and this RNA sequence makes a triplet codon which makes an amino acid.

This code is universal and shows redundancy, by this more than one codon makes the same amino acid, if any nucleotide sequence change occurs between the DNA and RNA, there is no effect on the protein sequence.

Therefore, protein is the linear sequence of amino acid if any change occur in the one codon, but leads to create the same amino acid, do not affect the protien.

#SPJ3

The extra codons mean the code is more resilient- small errors can still result in the same protein being produced. The other advantage is that in some cases, a single strand of genetic material might code for more than one protein or enzyme, depending on how it is read. This means that one method of reading will produce the same output, but the second or third method of reading (starting from a different place on the strand) can produce other, entirely different materials. This concept is like a palimpsest.
