Answer:
Archaea
Explanation:
Archaea is another term for Archaebacteria. also known as Bacteria which fits all the traits from the question.
d. the living world. Biologists need to use the living world in order to back up the scientific method.
The correct answer is A. Decline in vision
Explanation:
The term "middle age" is used to describe the time span between 45 and around 65 in human life. During this, important changes occur in terms of senses, this age usually implies a decline in senses including pain, taste, smell, and vision. In terms of vision, it is common during middle ages people began experiencing blurring vision or weakened vision as during this age conditions such as presbyopia, glaucoma, cataracts, among others. Additionally, the decline in vision in this age is commonly related to other conditions such as diabetes, the use of medicines and also jobs that are visually demanding. Thus, in middle age, people commonly experience a decline in vision.
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
