Why do prokaryotes not undergo mitosis?
Answers
Hope that helped
The DNA of prokaryotes is not enclosed within a membrane, and is instead localized to a region called the nucleoid. This DNA acts as the prokaryote’s only chromosome, so the process of DNA replication is much quicker. After DNA replication, the original chromosome and its copy seperate. A cleavage furrow forms between the cell, the cell eventually pinches in half, and two identical daughter cells, each with an identical chromosome, are formed.

Summarize Why conduction occurs in all materials but convection only occurs in liquid and gases.
Answers
Answer:
Convection only happens with fluids, materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can't flow and since they can't flow, there is no convection. The way heat transfers through solids is conduction.

Government began with:
Moses
God
Abraham
The_____was the first unit of government.
Legislature
Family
State
The need for government grew in Old Testament days when families grew into:
tribes
countries
communities
states
Answers
Answer: abraham, family, tribes
Explanation:
According to the statement, Government began with Moses, God, and Abraham. However, the statement does not provide a clear answer to the questions.
Regarding the first unit of government, the statement does not provide a clear answer. It is possible that the statement is referring to the family as the first unit of government. In the Old Testament, families were the basic unit of society, and patriarchs had significant authority over their households. Family is most likely the best answer,
As for the need for government in Old Testament days, the statement suggests that families grew into tribes. The twelve tribes of Israel were descended from the twelve sons of Jacob, and each tribe had its own identity, leadership, and territory.
Therefore, based on the statement, the first unit of government could be the family, and families grew into tribes in Old Testament days.
Explain how deep currents form and move in the ocean.
Use complete sentences.
This is science 6th grade. Amplify.
Answers
Deep ocean currents are formed by differences in water density, which are usually caused by differences in temperature and salinity. The density of seawater increases as the temperature decreases and the salinity increases. This means that colder and saltier water is denser and sinks to the bottom of the ocean, while warmer and less salty water is less dense and rises to the surface.
These differences in water density set up a circulation pattern in the ocean known as thermohaline circulation. In this circulation, cold and dense water sinks in the polar regions and flows towards the equator, where it slowly rises to the surface. This creates a global conveyor belt of deep ocean currents that circulate water around the world's oceans.
The movement of deep ocean currents is also influenced by the Earth's rotation and the shape of the ocean basins. The Coriolis effect, which is caused by the Earth's rotation, deflects deep ocean currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The shape of the ocean basins also influences the movement of deep ocean currents, as currents tend to flow around the edges of the basins and are deflected by land masses and underwater ridges.
Overall, deep ocean currents are an important part of the global ocean circulation system and play a crucial role in regulating Earth's climate by transporting heat and nutrients around the world's oceans.

What do you think the distribution of fossil fuels on Earth suggests about what Earth was like millions of years ago? Support your answer with evidence.

Answer: Years ago, when prehistoric animals and plants died, layers of rock and dirt gradually buried them. Over millions of years, heat and pressure from Earth's crust ... that are useful to humans, like fossil fuels, are called natural resources. ... life and provides real-life examples such as scientist have found fossals in museums
Explanation:
The distribution of fossil fuels on Earth suggests that the population was low when compared to now and there was also less technology adopted.
Plants and animals which died millions of years ago were gradually covered
with dust through wind erosion as a result of less technological innovation
such as burying in coffins etc. They were put in tombs which made fossils to
be discovered as a result of direct contact with rocks and soil components.
The population of plants and animals were also lesser than then which is why fossils are sparingly distributed across the world.
