Most people feel confident that they could identify a living thing from a nonliving thing, but sometimes it’s not so easy. Scientists have argued for centuries over the basic characteristics that separate life from non-life. Some of these arguments are still unresolved. Despite these arguments, there do seem to be some generally accepted characteristics common to all living things. Anything that possesses all these characteristics of life is known as an organism. 1.The scientific term for a living thing is a(n) _____________________

Answers
Answer:
b. gene; DNA strand; chromosome; genome
Explanation:
The smallest unit in genetic structure will be gene which is a segment of DNA. After that comes DNA strand which may contain one or more genes. A chromosome is a larger structure as compared to a DNA strand because a chromosome contains two DNA strands which are joined at centromere. All the chromosomes in an individual collectively form genome so genome is an even larger term when it comes to genetic information.
Final answer:
Genetic information can be organized from smallest to largest as follows: DNA strand, gene, chromosome, and genome. The correct answer from your list is 'b'.
Explanation:
The levels of genetic information, organized from smallest to largest, are as follows: DNA strand, gene, chromosome, and genome. Let's break it down step by step:
- DNA strand: This is the smallest level and forms the building blocks of genetic information.
- Gene: Genes consist of a length of DNA that codes for a specific protein or function.
- Chromosome: A chromosome is a combination of many genes and is packaged into a single structure. Humans have 46 chromosomes.
- Genome: The genome is the complete set of genetic material in an organism. It includes all the genes and chromosomes.
Therefore, the correct answer from your list would be option 'b': gene, DNA strand, chromosome, genome.

Answer:
1) C. Blood pressure cuff, towels, bitten cookies
2) C. Vector
Explanation:
1) C. Fomities are things that tend to carry infections. Here C is the most plausible answer
2) C. Vector. You often hear this when we talk about diseases that can spread like when mosquitoes spread disease, they act as vector
Final answer:
Fomites are non-living objects that can carry and transmit disease. In your question, the correct answer for fomites would be option C. For the second question, an insect transmitting a disease agent is known as a vector. Option c is the correct answer.
Explanation:
The term fomites refers to inanimate objects that, when contaminated with or exposed to infectious agents (such as bacteria, viruses, fungi), can transfer disease to a new host. Option A. Door handle, soap dispenser, a dog infected with rabies virus is partly correct because while door handles and soap dispensers can be fomites, a dog cannot be as it is a living organism. Similarly, option B. Pencils, a mosquito, unwashed iceberg salad partly fits the definition, but again, a mosquito (a living organism) can't be a fomite, it acts as a vector. Finally, option C. Blood pressure cuff, towels, bitten cookies are all non-living objects and thus can be considered as fomites. This means the answer to your first question isn't D. All choices are correct, but rather it's C. Blood pressure cuff, towels, bitten cookies.
In your second question, an insect that transmits a causative agent from an infected organism to an uninfected one is called a vector. So, the answer is C. Vector.

Answer:
Repetition
Explanation:
In science, the act of performing an experiment several times is called repetition. This involves obtaining multiple trials of an experiment in order to ensure accuracy and precision.
Multiple trials ensures that the best result which eliminates errors represents the findings.
Repetition gives a pool of important statistics to work with which can raise the confidence limit and provide more representation.
