What is prairie land?

Large expanses of grassland that are level or undulating are known as prairies.

These grasslands can be found in Minnesota in a variety of habitats, including shortgrass prairies perched high on the bluffs of the Minnesota River, enormous fields of big bluestem up to 8 feet tall, and sparsely vegetated sand dunes.

The Great Plains are made up of the Canadian provinces of Alberta, Manitoba, and Saskatchewan as well as the American states of North Dakota, South Dakota, Montana, Nebraska, Kansas, Oklahoma, Texas, Wyoming, Colorado, and New Mexico.

Sheep are currently the animal raised on prairie terrain. Millions of prairie dogs and thousands of bighorn sheep were nourished by vast, uninterrupted horizons of continuous grasslands.

Additionally plentiful were the birds, which included more than 3 billion passenger pigeons, various grouse species, and greater prairie chickens.

Thus, the correct option is A.

Answers

Answer:

Explanation:

attempted to control their population growth

The fact that people have historically prioritized short-term benefits above long-term sustainability is a significant factor in how severely humans have impacted the ecosystem.

Thus, human actions like deforestation, pollution, overfishing, and the burning of fossil fuels have historically been motivated by short-term economic or resource requirements without taking the long-term effects on the environment into account.

The stress on ecosystems and natural resources has grown due to population expansion and rising demand. Unsustainable practises, insufficient regulation, and a lack of awareness have all contributed. To solve these problems, we need to adopt more environmentally conscious behaviors by raising public knowledge of environmental issues.

Animal is a Eukaryotic

Plant is a Eukaryotic

Explanation:

Prokaryotic and eukaryotic cells have several differences. Which statement below is not one of those
differences?
Prokaryotic cells are found in the domains Eubacteria and Archaea.
Eukaryotic cells have organelles for processes like respiration or photosynthesis.
Prokaryotic cells cannot make their own proteins.
Eukaryotic cells are generally ten times larger than prokaryotic cells.

Answers

The third choice would not be a difference. Both prokaryotic and eukaryotic cells make proteins, so the statement that “prokaryotic cells cannot make their own proteins” is false.

prokaryotic cells cannot make their own proteins, the statement  is false. Thus the option C is correct.

What are the distinguishable features of prokaryotes and eukaryotes ?

Prokaryotic cell are unicellular as it is made up of single cell and the size ranges from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular, the size ranges from 10 μm – 100 μm in diameter.

cell wall is present in prokaryotes which involve in providing protection of the cell where as only in plant cell wall is present; True Nucleus is absent in prokaryotes instead of nucleus, nucleoid is present which carry genetic material while in eukaryotes true nucleus is present.

The Ribosomes are Smaller in size and 70s type in prokaryotic cell where as  the ribosome is larger in size with 80s type in eukaryotic cell larger in size and linear shaped ribosomes are present.

All the metabolic and physiological activities occur in a single cell of  prokaryotes where as the metabolic and physiological activities occur in different organelle.

Thus the option C is correct.

Answers

Answer:

C). Seafloor spreading.

Explanation:

Paleomagnetism is characterized as the 'study of the account of direction and strength of magnetic fields of the Earth in sediments, rocks, etc.' The hypothesis that was authenticated by using this study would be 'seafloor spreading' by displaying that magnetic reversal as strips of rotating polarity in gradually disseminating seafloor. This description of magnetic stripping by employing paleo-magnetism made the scientists believe that alternate crusts are being frequently made under ocean/sea. Thus, option C is the correct answer.

1 poin Students are discussing what they know about cellular transport. Their explanations are displayed in the table. Which student(s) gave an accurate statement regarding cellular transport? * EXPLANATION Passive transport is the movement of molecules from high to low concentration. 2 The sodium-potassium pump is an example of active transport because it uses energy 3 Molecules move against the concentration gradient in passive transport. 4 Diffusion and osmosis are both examples of passive transport. O Student 1 only O Students 1 and 2 Students 1, 2, and 4 O Students 2, 3, and 4​

Answers

Answer:

Students 1, 2 and 4

Explanation:

Passive transport goes from the higher concentration to the lower concentration in favor of the concentration. Student 3 referred to this as active transport and that is not right.

Simple passive diffusion, facilitated diffusion (via channels and carriers), and active transport are the fundamental forms of membrane transport. A bilayer membrane requires energy to flow through, even with simple passive diffusion. Thus, option C is correct.

What are the cellular transport mechanism in cell?

The molecules will migrate from a lower concentration to a greater concentration during active transport.

Energy in the form of ATP is needed for this cellular transport molecule to function. Based on their purpose, the active cellular transporters are divided into four categories.

The sodium-potassium pump in the human body serves as a practical illustration of active transport. Here, potassium ions remain inside the cell while sodium ions are outside the cell.

Therefore, Exocytosis, endocytosis, antiport pumping, and symport pumping are the different types of active transporters.
