Some animals look things from very far distance and others not see from far distance why?
olganol [36]

Answer:

The brain gets better with practice, so routine actions like walking become second nature. That is why your first time on the monkey bars is harder than your 100th time.

So how does the brain judge distance? The key for animals — like monkeys and humans — is in our eyes.

Where these different views overlap is how the brain is able to calculate the difference in distance and to judge depth.

This happens because the closer an item is to you, the greater the relative difference between the eyes will be compared with the object. The farther away an item is, the smaller the relative distance between the eyes will be. Our brain is great at remembering patterns, and it remembers the differences that each eye is seeing and correlates it with a distance. It can also find the distance by calculating the “convergence,” or how crossed your eyes become while looking at something. The more crossed your eyes become when looking at an object, the closer the object.

Main sequence stars can be classified according to which characteristics
miskamm [114]

Stars are classified based on the spectral type (i.e. a means to measure the photospheric temperature and density by getting information about the ionisation state).

Under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type) (Harvard Spectral classification based on the surface temperature of the stars). A luminosity class is added to the spectral class using Roman numerals (Yerkes Spectral classification). This is based on the width of certain absorption lines in the star's spectrum (0 or Ia+ - hypergiants, I - supergiants, II - bright giants, III - regular giants, IV - sub-giants, V - main-sequence stars, sd - sub-dwarfs, and D - white dwarfs).

Genes from parent to child remain the same in which type of reproduction?
lesya [120]
C coz asexual means no mixing gametes between male and female parents. Child and parent is GENETICALLY IDENTICAL. can be found in plants. Examples include rhizome and bulbs.
Sexual reproduction involves both sex and two (haploid) gametes produce one (diploid) zygote
Inbreeding reduce genetic diversity coz parents of similar gene sequence produce offspring. Never lead to genetically identical offsprings because of crossing over of non-sister chromatids in meiosis I, random assortment of chromosomes in meiosis I, random fusion of sperms and eggs during fertilisation and mutations.
Selective breeding does not interfere directly with gene contents, only select individuals with preferable traits for reproduction to increase the chance of producing offsprings with said traits. Other traits of parent and offspring could be different.
