Answer: An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Which sentence most accurately describes the daily growth rate of plants?
A- average plant height divided by total number of plants
B- sum of individual plant heights divided by number of days
C- sum of individual plant heights , divided by , total number of plants
D- average change in plant height, divided by, number of days
I will give BRAINLIEST to whoever answers first, AND answers correctly
Answer:
I would say D.
Explanation:
D talks about the change in plant height and it asks the growth rate. growth rate is measured by the change. Hope this helps(:
The diagram shows a eukaryotic cell.
Which of these functions is NOT performed by the organelles labeled X as they interact with other structures within the cell?
A) The organelles destroy harmful materials that have entered the cytoplasm
B) The organelles digest food that passes into the cell through the cell membrane.
C) The organelles break down other organelles such as mitochondria when they are worn out.
D) The organelles carry genetic material from inside the nucleus to the chloroplasts for reproduction.
The organelles carry genetic material from inside the nucleus to the chloroplasts for reproduction.
The correct option is D.
Which cells are organelles?It's also crucial to remember that eukaryotes, being one of the three main cell divisions, are the only ones to have organelles. Prokaryotes, which include the other two major divisions of bacteria and archaea, lack membrane-bound organelles.
What tasks do organelles perform?Like an organ in the body, an organelle is a subatomic structure that performs one or more particular functions for the cell. Some of the more important cell organelles are the nucleus, which stores genetic material, the mitochondria, which provide energy stored, and the golgi apparatus, which assemble proteins.

The answer is D
If a person is nearsighted, what type of lens will their glasses have to correct their eyesight?
converging lens
diverging lens
flat lens
A concave lens is called a diverging lens In concave lens, spherical surfaces are recessed inwards.
It is thinned out in the middle.
When parallel beam of light is passed through concave lens, light rays spread out to different directions.
Hence, a concave lens is called a diverging lens.
Nearsightedness (myopia) is corrected with lenses called “minus power lenses.” They are concave-shaped and help the eyes focus light properly. Myopia causes a person to see distant objects as blurry. Prescription eyeglasses or contact lenses can usually correct this blurry distant vision.
The focusing power of an eye with myopia is stronger than a normal eye. It brings light to a focal point in front of the retina, instead of on the retina.
A lens used to correct myopia works by reducing the focusing power of the eye. This is why it is called a "minus power lens" (or "minus lens").
Minus lenses are concave in shape. In other words, they are thinnest at the center and thicker at the edge. This lens shape moves the focus of light from in front of the retina directly onto its surface. This shift corrects the blurry distance vision caused by nearsightedness.
The power of a lens that corrects myopia is measured in units called diopters (D). The lens powers on an eyeglass prescription for myopia always begin with a minus sign. The higher the power number of the lens, the more myopia it corrects.
For example, a -6.00 D lens corrects twice the amount of nearsightedness as a -3.00 D lens.
High-index lenses are typically recommended for correcting nearsightedness greater than -3.00 diopters. They are thinner and lighter than regular plastic lenses, so they are more attractive and comfortable.
Answer:
Its actually concave lenses
Explanation:
As someone who wears glasses, there are different lenses or 'levels' of eyesight that requires a personalized prescription.
Lucille is finding it difficult to play soccer after school. Her doctor thinks that her cells might not be getting enough oxygen. When Lucille talked about it with a friend, her friend said there might be a problem with Lucille’s respiratory system or circulatory system.What do Lucille’s cells need in order for her body to function properly? How might a problem with Lucille’s respiratory system or circulatory system make it difficult for Lucille to play soccer?
