Answer:
250 nm
Explanation:
Data provided in the question:
Length of the bacteria cell = 2.5 micrometers (µm)
Now,
We know that,
1 m = 10⁶ µm
or
1 µm = 10⁻⁶ m
also,
1 m = 10⁹ nm
or
10⁻⁹ m = 1 nm
Therefore according to the above results we get,
2.5 micrometers (µm) = 2.5 × 10⁻⁶ m
and,
2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm
= 2.5 × 10³
= 250 nm
Answer:
O Community
Explanation:
A community is made up of many populations within a specific area a certain period of time.
- A population is group of organisms of the same species that can interbreed and produce viable offspring
- Populations of organisms in a specific area or region is known as a community.
- An example is a community made up birds population, human beings, lizards etc.
Answer:
Patches of fibrocartilage formed in the healing of a fracture are called <u>soft callus</u>, whereas the bony collar formed around the fracture is called <u>hard callus</u>.
Explanation:
In the fibrocartilage or soft bone callus phase, the necrotic bone is removed by osteoclastia and dead soft tissues are being removed by macrophages. The fibroblasts are activated and a granulation tissue is generated that supposes the appearance of new vessels and, with them, the arrival of more connective tissue cells. A tissue called fibrous callus or fibrocartilage begins to form, composed of a poorly structured amalgam of fibrous tissue, cartilage, and amorphous bone.In hard callus, bone and later cartilage are deposited in the growing historical mass. The two collars of callus, fixed to the bone at some distance from the fracture, they grow upwards and towards each other, forming an arc on focus.
In modern physical cosmology<span>, the </span>cosmological principle<span> is the notion that the spatial distribution of matter in the universe is homogeneous and isotropic when viewed on a large enough scale, since the forces are expected to act uniformly throughout the universe, and should, therefore, produce no observable</span>
