Answer:
The first living organism on Earth are Bacteria in the first era.
Explanation:
Bacteria are the first organism to leave be on Earth. They came into existence about 3.5 billion years in the first era in the waters of small oceans. Then there were anaerobic hetetrophic bacteria because the atmosphere was free of oxygen before. Cyanobacteria then became the first autotrophic organisms and first photosynthesizer that release oxygen to the atmosphere after photosynthesis.

If the cell cycle lasts 36 hours and mitosis takes 25% of the cell cycle, how many hours will the cell be in mitosis?
Answers
(P+M+A+T) — the sum of all cells in phase as prophase, metaphase, anaphase and telophase, respectively; N — total number of cells.
Mitototic index (MI) is 3/25000 x 100 = 1.2 %
From the cell cycle, 1.2% is mitotic and the rest will obviously be interphase.
So, 1.2% is 30 minutes, so 100% (length of total cell cyle) is 2500 minutes (42hours).
I hope this helped you.

Which is not a likely economic tool to address environmental issues?
Emissions fees and taxes
Responsibility for a product from production to disposal
Small business liability relief
Defunding government regulation
Answers
Explanation:
Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports
Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS

Answers
Answer:
(4) 5000°C and 3.0 million atmospheres
Explanation:
The inferred temperature is 5000°C and pressure of Earth's interior is 3.0 million atmospheres at a depth of 3,000 kilometers. At the depth of 3000 kilometers, core of the earth is present which is very hot and it is mostly consist of iron. The inner core has a radius of about 1,220 kilometers while the outer core is about 1,400 miles thick which comprise of iron, Nickle, gold, platinum, and uranium elements.

In mature animals when do cells still need to differentiate?
Answers
Answer:
As an organism develops, cells differentiate to form different types of cells. Most types of animal cell differentiate at an early stage. Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement.
Explanation:
''.''
In mature animals cells differentiate during : Repair and replacement of animal cells
Cells differentiate in organisms and plants to create more cell types, as the organism and plants continue to mature. While cell differentiation in animals occur mostly before maturity, plants cells continue to differentiate until they die.
While in mature animals, cells differentiates at maturity only when the cells of the mature animal needs repair or replacement due to damage caused to the a cell or tissue.
Hence we can conclude that in mature animals cells differentiate during repair and replacement of cells.
