blood is distributed from the surface of a bone to deeper central canals through channels known as
Blood is distributed from the surface of a bone to deeper central canals through channels known as Haversian canals.
What is Haversian canal?
Haversian canals are small channels that run through the bone tissue, and they serve as the highways for blood vessels, nerves, and lymphatic vessels. They distribute blood and other essential nutrients to the bone tissue and allow for the removal of waste products.
These canals are surrounded by concentric layers of bone matrix, known as lamellae, and they help to maintain the structural integrity of the bone. The distribution of blood through the Haversian canals is essential for the health and maintenance of the bone tissue.

What properties of photosynthetic pigments allow pigments to absorb light of only certain wavelengths? Select all that apply.
Light of any energy level can boost an electron of the pigment molecule to a higher energy level in order to be absorbed.
Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.
Some pigment molecules lack a light-trapping region.
All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely
between Its atoms.
The properties of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; ( B and D )
Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed.All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between Its atoms.The Green pigment found in plants ( i.e. photosynthetic pigment ) that absorb light energy used by plants during photosynthesis is the chlorophyll. It absorbs light energy based on the wavelength of the visible light while reflecting visible green light due to its wavelength.
The reflection of the visible green light by the chlorophyll gives the plants leaves the green color it possesses.
Hence we can conclude that The property of photosynthetic pigments that allow pigments to absorb light of only certain wavelength is ; Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. and statement D.

what is the modification of plant?why are different parts of plants modified? write
please help:(
Answer:
what is the modifications of plants?ans -In some plants, the roots change their shape and get modified to absorb and transport water and minerals from the soil to different parts of the plant. They are also modified for support, food storage, and respiration. The root modifications perform two major functions- Physiological and Mechanical.
Cell Division: Parts of Nephron
Leaf Structure: Genotype Meaning
2.why are different parts of plants modified?
ans-Certain parts of a plant undergo modification in order to adapt to their surroundings and environmental conditions. These modifications help them in their survival against odds. For example, the leaves in a cactus plant are modified to spines to reduce the surface area and hence water loss by evaporation.

baby names connect to gender, and names flow from male to androgynous to female but never in reverse. the reason for this is that
In most cultural and religious doctrines, masculinity seems to be weighted well above the feminine gender. Hence, greater level of power or hierarchy is leveled towards the masculine gender. Hence, the reason for the trend in m naming pattern is due to the power alloted to male species.
Naming pattern usually follow the standard trend of having a root which is meant for the male kid, before transitioning to a fairly refined or similar name which is attributed to female kids. Intermediate names which can be used for either gender are called androgynous names sometimes precedes the female naming convention.Therefore, the pattern of naming with the masculine version coming first is due to the higher heirachical power given to males.

What is RNA?Full form of RNA has ribonucleic acid and it has a nucleic acid which has been found in almost all cells that are living and RNA has mostly similar to DNA but there is one difference between RNA and DNA and the difference is that RNA has single stranded but DNA is double stranded.
The RNA has backbone has made up of the phosphate group which has arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
The main function of mRNA is it work as imedieter between protein and DNA which is utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA is to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
Therefore, Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule.
