that is? Does this make you think of any other questions that you have? Record your thoughts below.


help

Answers

I think that it is warmer because there is less water to keep warm.

I don’t know if that made sense

Answer:

depends on if its exposed to more sun/light and how murky it is. its harder for light and heat to go further in the deeper lake because the photons bounce off the water molecules much easier seeing as theres more of them. but there's not as much mass refracting and dispersing light in a shallow lake

What is ONE power of the Federal government?
2. What is ONE Power of the State governments?
3. What is ONE power share by BOTH the State and Federal governments?

Answers

Answer:

The federal government is composed of three branches: legislative, executive, and judicial. Powers are vested in Congress, in the President, and the federal courts by the United States Constitution. The powers and duties of these branches are further defined by acts of Congress, including the creation of executive departments and courts inferior to the Supreme Court. The government was formed in 1789, making the United States one of the world’s first, if not the first, modern national constitutional republic. It is based on the principle of federalism, where power is shared between the federal government and state governments. The powers of the federal government have generally expanded greatly since the Civil War. However, there have been periods of legislative branch dominance since then. Also, states’ rights proponents have succeeded in limiting federal power through legislative action, executive prerogative, or constitutional interpretation by the courts. A theoretical pillar of the United States Constitution is the idea of checks and balances between the powers and responsibilities of the three branches of American government

2.Powers not granted to the federal government are reserved for states and the people, which are divided between state and local governments.

3.)There is an ongoing negotiation over the balance of power between the two levels. ... A. 2 (EK). States and the federal government have both exclusive powers and concurrent powers

If you had a choice of what type of reproduction you would use to take over the planet which one would it be

Asexual or sexual, which one would you choose? Describe the reason

Can someone help me pls!?

Answers

Answer: Asexual

Explanation:  

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual reproduction is the primary form of reproduction for single-celled organisms such as archaea and bacteria. Many eukaryotic organisms including plants, animals, and fungi can also reproduce asexually. In vertebrates, the most common form of asexual reproduction is parthenogenesis, which is typically used as an alternative to sexual reproduction in times when reproductive opportunities are limited.

Answer:

Asexual

Explanation:

I would choose asexual reproduction because it only involves one parent; therefore, it is much easier. As well, all of the offspring would be genetically identical. Last but not least, it would help with taking over the planet because it is much faster than sexual reproduction. Hence, a larger number of offspring/organisms would be produced at a higher rate. Asexual reproduction would easily take over the planet.

  There is no liver transplant facility in Nepal. One of my uncles ended up paying 85 lankhs  in one  of the hospitals in India for the transplant. If good services are provided , we may retain that money in Nepal. There a lot of unskilled and unemployable engineering graduates. Less than 0.5% of the graduates in Nepal are employable. They are bound to work as waiters in foreign countries. This will change with quality education.

Hospitals will be equipped  with great equipment.

FOOD

Agriculture system will be changed. I would thrive to change traditional agriculture system in Nepal. With technology, the productivity will go high.

I have a lot of plans. If I were PM or the president with sufficient power, there would a lot of things to set straight. But here, I want to mention significant ones.

Education: Reduce college and school fees as much as possible. Make some faculties free of cost (Government sponsored). After all, Education is an investment in a Nation's future. So make it free or reduce expenses.

Sanitation : motivate people to clean their streets. Manage waste. Help children implement what they learn in schools about cleanliness.
