Answer:
D
Explanation:
The correct answer would be <u>Nucleic Acid</u>.
A typical nucleic acid has 3 components which include:
- A purine or pyrimidine nitrogenous base
- A phosphate group
- A 5-carbon sugar
The purine base includes adenine and guanine while the pyrimidine base includes thymine/uracil and cytosine. The 5-carbon sugar could be ribose or deoxyribose depending on if the nucleic acid is ribonucleic or deoxyribonucleic acid.
<em>The only macromolecule that contains the 3 components of the options A to D is the nucleic acid. Hence, the correct option is </em><em>D.</em>
Answer:
easy to produce, affordable, abundant
Explanation:
A non-renewable resource is defined as the natural resources which are not ereadily replaced through natural means and it takes thousands of years for their renewal. Example of non-renewable resource include Fossil fuels such as natural gas, oil and coal.
<u>There are many advantages of non-renewable resources such as:</u>
1) Easy to produce: non-renewable resources are easy to produce because processing stations can be easily developed for refinement and distillation of non-renewable resources.
2) Affordable and abundant: non-renewable resources are affordable and abundant in the earth. for example diesel and oil are good choices for powering vehicles.
Hence, the correct options are easy to produce, affordable, abundant.
B. defiantly b. because it can survive in most climates.
Answer: Option C) A sentence in the instruction book
Explanation:
A gene is a specific portion on the DNA that code for a functional protein. i.e DNA consists of several genes, and some non-coding sequences that are usually spliced off during post-translational modification.
In other words, a gene can be best described as each single, meaningful sentence in the instruction book for building an organism.
Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.
