Answer: Ecosystem
Explanation: An ecosystem consists of all the biotic and abiotic factors in an area and their interactions. A niche refers to the role of a species in its ecosystem. A habitat is the physical environment in which a species lives and to which it is adapted.
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years. And if the star is very small, with a mass only a tenth that of the Sun, it can keep fusing hydrogen for up to a trillion years, longer than the current age of the universe.
The question is incomplete as it does not have the options which are:
A. 8; 32
B. 10; 29
C. 12; 20
D. 5; 45
Answer:
The correct answer will be option-B
Explanation:
Trauma is the experience caused by the life-threatening events or events which help develop the psychological distress conditions.
The trauma can cause changes in the physiologic and psychological responses in humans. The CDC guidelines have stated criterion for immediate transportation of the person to the trauma centre in which one of the criteria is that if a person has the respiratory rate of less than 10 and greater than 29 will be transported to the trauma centre immediately.
Thus, Option-B is the correct answer.
Chromosome is a structure that contains DNA molecules packaged around histone proteins, therefore carries the heredity material. Chromosomes number determines whether a cell is haploid (n) or diploid (n). A diploid cell has both set of homologous chromosomes while the haploid cell has only one set. Nucleus is the cellular structure that is responsible for the localized storage of chromosomal DNA.
<u>Answer:</u>
CCGAGU
<u>Explanation:</u>
DNA transcription:
DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.
During transcription two strands of DNA are named differently i.e Template strand and coding strand.
Template strand:
Strand from which RNA is producing is known as template strand while
Coding strand:
The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.
Correct Answer:
Template strand from 5' to 3' reads GGCTCA. and
In this question CCGAGT is coding strand.
RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
CCGAGU
