C. Birds have the same arrangement of bases as flowers
The correct option is C.
An ocean is a very important abiotic factor in any environment and it have impacts on the climate of the environments where it is found. The ocean currents are driven by the global wind system, which is powered by the energy of the sun. These currents transfer heat to the polar regions from the tropics and brings about the cooling of their environment, thus giving rise to cool climate.
The answer to this question is letter d. heterotrphic
The following are the choices:
<span>A) prokaryotic
B) multicellular
C) antibiotic
D) heterotrphic
</span><span>Euglenoids are freshwater protists that are both photosynthetic and </span>heterotrophic,which means they acquire nutrients like other animals, besides it being able to produce its own food source.
Answer:
The answer is 'D'. Transcription is the process by which a single stranded mRNA is formed from the double stranded DNA.
Explanation:
The central machinery of biology involves three processes- replication, transcription and translation. The process by which DNA doubles itself is called <u>replication</u>. In translation, protein is formed from the messenger RNA or mRNA. The major steps involved in transcription are:
- <em>Initiation</em>
- <em>Elongation</em>
- <em>Termination</em>
In the process of translation, amino acids bind together in the <u>ribosome</u> to form a polypeptide chain.
Answer:
Alternation of generations (also known as metagenesis) this type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that will have distinct haploid sexual and diploid asexual stages. A multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes is form in these group, made up of n pairs.
A mature sporophyte will produces haploid spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n.
In the haploid cell the spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes.
