Answer:
✔️Facilitated diffusion does not require any of cell energy.
Explanation:
The above structure A is known as Cell Membrane. It is a permeable membrane through which materials are diffused or transported in and out of the cell.
Option A is true for structure A because facilitated diffusion does not require the cell's energy. Facilitated diffusion is passive transport of molecules or ions across the membrane which is spontaneous.
It is passive because facilitated diffusion does not directly require chemical energy from ATP hydrolysis. What happen is that molecules and ions move down their concentration gradient. This movement reflects their diffusive nature.

Why do globes lean sideways?
A.To allow them to spin easier
B.To demonstrate gravity
C.To demonstrate the passing of the seasons
D.To demonstrate the tilt of the Earth's axis
Answers
Answer:
D
Explanation:
Globes lean sideways To demonstrate the tilt of the Earth's axis. Option D is correct.
Globes lean sideways to demonstrate the tilt of the Earth's axis. The Earth is tilted on its axis by about 23.5 degrees. This tilt is what causes the changing seasons on Earth.
When a globe is tilted, it helps us visualize how different parts of the Earth receive different amounts of sunlight at different times of the year. For example, during the summer in the northern hemisphere, the North Pole is tilted towards the Sun, so it receives more direct sunlight and experiences warmer temperatures. At the same time, the South Pole is tilted away from the Sun, receiving less direct sunlight and experiencing winter.
By showing the tilt of the Earth's axis, globes help us understand why we have seasons and why they occur at different times in different parts of the world.
To summarize, globes lean sideways to demonstrate the tilt of the Earth's axis, which helps us understand the changing seasons on Earth. Option D is correct.

Which statement is true about Earth's outer core? A. It is believed to be made mostly from copper deposits. B. It is the outermost layer of the planet. C. It is composed of liquid metal. D. It is the thinnest layer of the planet.
Answers
Answer: c
Explanation: makes sense
The Earth's outer core is mainly composed of the liquid metals such as iron and nickel. Thus, the correct option is C.
What is the outer core of the Earth?The outer core begins approximately in the range of 2,889 km or 1,795 miles beneath the Earth's surface at the core-mantle boundary of the Earth and ends at 5,150 km or 3,200 miles beneath the Earth's surface at the inner core boundary of the Earth.
The outer core of the Earth is mostly composed of liquid iron and nickel. The Nickel and Iron alloy of the outer core is very hot, between 4,500° and 5,500° Celsius temperature. The outer core of the Earth is mostly made up of iron and nickel elements. This alloy is often written as NiFe because it is a combination of their chemical element symbols.
Therefore, the correct option is C.

Answers
Answer:
1a. The template DNA strand, from which the mRNA is synthesized, is 5’ CAAACTACCCTGGGTTGCCAT 3’
(RNA synthesis proceeds in a 5’ à 3’ direction, so the template strand and the mRNA will be complementary to each other)
b. The coding DNA strand, which is complementary to the template strand, is 5’ ATGGCAACCCAGGGTAGTTTG 3’

Two photographers take time-lapse photos of the night sky. One of them is at the equator. The other is at the south pole. Which photo will show stars that never rise or set? Explain
Answers
Answer: South pole.
Explanation:
The equator is filled with non-circumpolar stars which means the stars sets in the sky. The north and south pole is full of circumpolar stars which means they never set.
If two photographers take time-lapse photos of the night sky with one being at the equator and the other at the south pole, the photo by the photographer at the south pole will show stars that never rise or set.
The stars that never rise or set is known as the circumpolar stars and are usually found close to either of the earth's poles - north or south pole.
This means that the photographer at the equator which is an equidistance from the two poles will not be able to capture the circumpolar stars.

b:biotechnology
Answers
Answer:Biotechnology is a broad area of biology, involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields
biology the laws and phenomena relating to an organism or group
Biology: The study of living organisms is called biology
Biotechnology: Application of technologies in the field of biology.
What is the difference between biology and biotechnology?Biotechnology is a subfield of biology, which is a science. Biotechnology is the use of biology for human benefit, whereas biology is the study of living things. Biotechnology uses a variety of methods, such as the genetic engineering of bacteria, to produce industrial goods.
The anatomy of living things is what distinguishes biology from biotechnology. The anatomy and physiology of living things are the main topics of biology. Contrarily, biotechnology is concerned with technology. It has nothing to do with the least important aspects of a living thing's anatomy and physiology.
Hence, this is a detailed explanation of biology and biotechnology.
