Explanation:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
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.

State TWO reasons how bacteria can be useful to humans,
Answer: Creating products, such as ethanol and enzymes.
Making drugs, such as antibiotics and vaccines.
Making biogas, such as methane.
Cleaning up oil spills and toxic wastes. Bacteria have long been used by humans to create food products such as cheese, yoghurt, pickles, soy sauce and vinegar. We are also able to use bacteria to break down our sewage and to clean up oil spills.
Explanation:
Answer:
They help to digest substances that the human body cannot break down, like many carbohydrates and things called short chain fatty acids. Friendly bacteria give you protection from the microorganisms that could cause serious illness.

Relative to the length of time life has been on Earth, have modern humans appeared recently or in the distant past?
pLeAsE HeLp Me...
Answer:
recently
Explanation:
earth has had like for billions of years
humans have been here for hundreds of thousands
so to put it simply humans have been here for like 1/10000 of earths lifetime and that's very inaccurate but ik just making a point
In this exercise we have to explain why human beings are considered recent in relation to the time of the earth, so we can say that;
taking into account that the earth is 4.5 billion years old and human beings only existed for approximately 200 thousand years, we can say that we are extremely recent.
How old is a human being on Earth?Anatomically modern humans have their first fossil record in Africa, about 195,000 years ago, and molecular biology studies provide evidence that the approximate time of the common ancestral divergence of all modern human populations will have been 200,000 years ago.

Which of the following traits is encoded in your DNA?
A
Your personality
B
Your likes and dislikes
C
Your intelligence
D
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.

The Dart Frog is a brightly colored frog. These bright colors could mean that this frog is poisonous, warning predators to stay away. Plants in the rainforest are normally crowded and have very little space. The big leaves of a Hosta Plant allow the plant to receive as much sunlight as possible when the sun is out.
What type of adaptations are these? Compare and contrast the adaptations of the Dart Frog and the Hosta Plant. Your answer should be 3–4 sentences long.

1)poison dart frogs live in rainforest habitats in Central and South America.
2)they can be found in trees, as well as under leaves and locks and rocks on the floor of the forest.
3)because of their size from 1/2 to 2 inches long, they are hard to see.

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.

Answer:
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.
What is a mutagen?
A. A way to test for chromosomal mutations
B. A type of mutation involving chromosomes
C. An environmental agent that changes DNA
D. A mutation that is inherited from parents
The answer to the question is that Mutagen is an environmental agent that changes DNA.
Types of Mutagens:
Physical mutagens: Ionising radiation, such as X-rays, gamma rays, and alpha particles, is one example. UV radiations can also act as possible mutagens.Chemical mutagens: Mutagens include arsenic, nickel, and chromium. Some organic chemicals, such as benzene, are also mutagenic in nature.Biological mutagens: Transposonas and viruses are two examples of biological mutagens. Furthermore, some bacteria, such as Helicobacter pylori, have been linked to an increased risk of stomach cancer.Thus we can conclude that A mutagen is a physical or chemical substance that permanently alters genetic material in an organism, generally DNA, increasing the incidence of mutations over the natural background level.
