Answer:
The statement is true.
Explanation:
When a chemical substance is dangerous for people's health, we speak of a toxic risk. This risk can materialize if exposure to the chemical agent is not controlled. Toxic substances are those substances capable of causing harmful effects in a living organism when they come into contact with it or when ingested, intentionally, accidentally, or deliberately. The toxic risk of a chemical product depends on two factors: the toxicity and the absorbed dose, where a series of factors influence: composition, properties, concentration, duration of exposure, route of entry into the organism and workload.
What was Charles Darwin's area of study?
Answer:
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

Plz help
Answer:
The ability of a microorganism to tolerate the effects of an antibiotic is known as antibiotic resistance. It's a certain kind of drug resistance. Antibiotic resistance develops naturally through random mutation, but it can also be engineered by putting a population under evolutionary stress. Bacteria will then transmit genetic information in a hominid-like manner once such a gene has been formed. Following the development of such a gene, bacteria may use plasmid exchange to transfer genetic information horizontally (between individuals). Multiresistant bacteria, also known as superbugs, carry several resistance genes. the reasons for it Transformation protocols can also be used to incorporate antibiotic resistance into a microorganism. This may be a good way to get artificial genes into a microorganism. Antibiotic tolerance is a product of natural selection in evolution. Antibiotic activity is a type of environmental pressure; bacteria that have developed a mutation that allows them to survive will continue to replicate. They will then pass this trait on to their children, resulting in a generation that is completely immune.

The adaptations of the Dart frog are as follows:
The Dart frog is native to the tropical environments of Central and South America which are humid conditions. These frogs are brightly colored and poisonous to their predators. Due to poisonous taste, other frogs perform mimicry to ensure their safety from predators.The adaptations of the Hosta plant are as follows:
Hosta plants are native to Northeast Asia, Japan, Korea, etc. The leaves of this plant are big and therefore it receives as much sunlight as possible when the sun is out. It requires fertile soil which is full of organic matter to yield proper growth and development. What is Adaptation?Adaptation may be defined as the adjustment of organisms to their environment in order to improve their chances of survival in that environment.
Therefore, the adaptations of the Dart frog and the Hosta plants are briefly described above.

What organic molecule contains a carboxyl functional group and an amino functional group?
A. DNA
B. carbohydrate
C. lipid
D. protein
The basic amino group (NH2), the acidic carboxyl group (COOH) and the specific organic R group (or side chain) for each amino acid make up an organic molecule known as an amino acid. Thus, option D is correct.
What is Structure of protein?
The linear arrangement of amino acids within a peptide or protein constitutes its fundamental structure.
Conventionally, a protein's main structure is described from amino-terminal end to carboxyl-terminal end. Ribosomes in cells are most frequently responsible for protein production.
Peptide bonds are created when amino acids condense to form protein structures. The main structure of a protein is its arrangement of amino acids.
The dihedral angles of the peptide bonds determine the secondary structure, while the folding of protein chains in space determines the tertiary structure.
Therefore, a protein organic molecule contains a carboxyl functional group and an amino functional group.

Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful--its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to develop the solution, etc.
Design criteria are the explicit goals that a project must achieve in order to be successful. ... Design criteria can be divided into primary and secondary criteria. Primary criteria are those that constitute a successful project; the project will be unsuccessful if it does not meet these goals.

Which of the following traits is encoded in your DNA?
A
Your personality
B

Your eye color
Answer:
D
Explanation:
it's your eye color because DNA makes up the genetic aspects of you. The other choices are something you can choose to improve or change.
Eye color trait is encoded in the DNA. So, the correct option is D.
What are Traits?A phenotypic trait is defined as a clear, observable and measurable characteristic of an organism that is the expression of genes in an observable manner. An example of a phenotypic trait is a specific hair color or eye color.
This is described as a distinctive characteristic of an individual that can be determined by genes, environmental factors, or a combination of both. Characteristics can be qualitative for example, as eye color) or quantitative for example, height or blood pressure.
Thus, Eye color trait is encoded in the DNA. So, the correct option is D.

what happens to the original cell's chromosome during fission?
Answer:
It is a austic kid
Explanation:
Explanation:
Fission or binary fission is a process of cell division, used by single-celled organisms (also known as prokaryotes). This division is a form of asexual reproduction and results in a genetically identical offspring. Prokaryotes contain a single DNA molecule. During the fission process, replication of this DNA molecules occurs and the cell ends up with two copies of DNA molecule. These molecules are separated and are attached to different parts of cell membrane. This part of fission process is followed by actual cell division into two daughter cells. Each daughter cell ends up with one DNA molecule. Thus, each daughter cell is identical to the parent cell in all respects and the number of chromosomes are same in both the parent and daughter cells.
In comparison, eukaryotes undergo sexual reproduction.
