Answer:
CCGAGU
Explanation:
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
Hybrid organisms contain DNA from both male and female parents but cloned organisms contain DNA from only one type of parent. Hybrid has superior character over its parents (improved hybrid vigor) but clones are 100% identical to their parent. Hybridization gives only one hybrid progeny, whereas through cloning unlimited identical organisms can be produced.
The replacement of one variant or strain of bacteria with another is primarily driven by selective pressures in the environment.
Bacterial populations are dynamic and can undergo changes in composition over time. The replacement of one bacterial variant or strain with another can be attributed to various factors, but one of the key drivers is selective pressures in the environment.
Selective pressures refer to the conditions or factors in an environment that favor the survival and reproduction of certain bacterial variants over others. These pressures can include factors such as changes in nutrient availability, pH, temperature, antibiotics, competition with other microorganisms, and interactions with host organisms. Bacterial variants that possess adaptations or traits that are better suited to the current environmental conditions will have a higher fitness and are more likely to thrive and reproduce. Over time, this can lead to the replacement of less fit variants with those that are better adapted to the prevailing selective pressures.
The process of replacement can involve natural selection, where the genetic diversity of bacterial populations allows for the emergence of advantageous traits through mutation and genetic recombination. The dynamics of bacterial replacement are central to understanding microbial evolution, the development of antibiotic resistance, and the interactions between bacteria and their environments.

The replacement of one variant/strain of bacteria with another is primarily driven by competitive advantages in adaptation and resource utilization.
This phenomenon, often observed in microbial communities, results from the intricate interplay between bacterial populations and their environment. Bacteria are remarkably adaptable and can rapidly evolve to exploit specific ecological niches. When a particular variant or strain gains a competitive edge in utilizing available resources or tolerating environmental conditions, it can outcompete its counterparts, leading to the replacement of the less adapted strains.
Bacteria's ability to undergo genetic mutations and horizontal gene transfer contributes significantly to their adaptability. Variants with mutations that confer advantages such as increased nutrient uptake or resistance to stressors tend to thrive in their environment. As these advantageous traits are passed on to subsequent generations, the dominant strain becomes better suited to its niche, gradually replacing less fit strains.
Furthermore, changes in the environment, such as alterations in nutrient availability or temperature shifts, can create conditions that favor specific bacterial variants. These environmental shifts can act as selective pressures, favoring the proliferation of strains better equipped to handle the new conditions.
In microbial ecosystems, the replacement of bacterial strains is a dynamic process shaped by a complex interplay of genetic, environmental, and competitive factors. Understanding these dynamics is crucial not only for grasping microbial ecology but also for applications in fields such as biotechnology, medicine, and environmental management.

b. Wheat and corn are common products of tropical plantations.
c. Most crops from tropical plantations are exported.
d. Cocoa, coffee and tea are common products of tropical plantations.
The right option is; b.
Wheat and corn are common products of tropical plantations is not true concerning tropical plantations.
Tropical plantations is a type of agriculture in which perennial plants are grown for several years. Tropical plantations are usually practiced in regions with humid, tropical climates and plants such as cocoa, coffee, tea, coconut, rubber and oil palm are the common crops that are cultivated. The crops are mostly exported and they serve as important source of income. Wheat and corn are not common products of tropical plantations .
Answer:
B
Explanation:
Answer:
$2 dollar per day
Explanation:
As per the definition of world bank, the salary of poor people is categorized into two groups -
a) Moderate Poverty - A person who earns less than 2 dollar a day is considered as one living in moderate poverty.
b) Extreme Poverty - While a person who earns less that 1.2 dollar a day is considered as one living in extreme poverty.
Thus, if Jim is categorized as poor then his daily salary must be less that 2 dollar per day
1.25 per day for plato
