Answer:
A. it is photosynthetic
Explanation:
A. it is photosynthetic - this is true - chlorophyll is a photosynthetic pigment that traps light energy to power food production. It present in green plants
B. it contains vascular tissues - this is false - eubacteria are single celled organisms that do not form tissues
C. it contains mitochondria - this is false - prokaryotic cells do not contain membrane-bound organelles like mitochondria
D. it is heterotrophic - this is false, plants and many bacteria are not heterotrophic, which means they consume other organisms for their food supply rather than creating their own (autotrophic)
Answer:
Adenine= 22%
Guanine= 28%
Cytosine = 28%
Explanation:
According to Chargaff rule, the amount of adenine in a double-stranded DNA is equal to the amount of thymine. This is due to the fact that adenine and thymine bases are complementary and form base pairs.
Likewise, the amount of guanine in a double-stranded DNA is equal to the amount of cytosine since guanine pairs with cytosine.
Given that percentage of thymine in a DNA sample = 22%
Percentage of adenine = 22%
Total percentage of adenine and thymine = 22+ 22 = 44%
Percentage total of guanine and cytosine bases = 100-44 = 56%
Percentage of guanine base in the DNA = 56 /2 = 28%
Percentage of cytosine base in the DNA = 28%

Aseptic technique is used to prevent microorganism to infect our body
One of the example of using aseptic technique is : wearing protective gloves when transferring bacteria an fungi to slides.
This action prevent those bacteria or fungi from transferring to our skin
hope this helps
Answer and Explanation:
The ecological footprint is an indicator of sustainability at an international level that integrates all the human impacts over the environment, considering the necessary resources and the generated residues to maintain the modern consumption model. It refers to the productive ecological surface needed to produce resources to consume by one person and to absorb the residues that are produced.
By constant contamination and indiscriminately use of natural resources the impact generated by human in the earth is unmeasurable.
The tragedy of the commons refers to how some people, acting by their own needs or interests, may exceed the use of natural resources, affecting their population and, therefore, other users. These individuals over explode resources thinking only in the present, but not in the future.
The ecological footprint as an indicator makes visible the unsustainable lifestyle of human beings, especially those of the first world. If this lifestyle would project to the rest of the world equally, natural resources would completely disappear. More developed countries are over contaminating and over exploding natural resources, affecting other countries of the third world, and even themselves.
