Answer: All galaxies are moving further away from us due to the expansion of the universe that happened after the big bang

CREDIT: AlpenGlow

Almost all galaxies are moving away from us.

Edwin Hubble found that galaxies are constantly moving away from us. According to his observations with the Hubble Space Telescope, galaxies are moving at different speeds. This shows that the universe is expanding. 

The farther away a galaxy is, the faster it is moving away. 

Based on the redshift that was calculated, Hubble noticed that the galaxies further away were moving faster. When light moves further away, it shifts towards the end of the spectrum (which happens to be red), thus it is called redshift.

How many food calories can a human burn up in an hour by exercising at this rate? (remember that only 20.0 % of the food energy
blsea [12.9K]

Human can produce a maximum mechanical power of 1/3 hp (horse-power).

Horse power is a unit of power, it equals 746 watt (watt is also a power unit, known to be equal to a joule per second)


So:

1 ph = 746 watt = 746 J/s

1/3 ph = 248.6 J/s

we're looking for the calories, so

1 joule = 0.239006 calories


So human produce a maximum mechanical power of:

248.6 J/s = 82.88 calories per second.


We're looking for the number of calories consumed in three hours, so:

82.88 cal/s = 82.88 cal/s * 3600 s * 3 = 895200 calories = 895.2 kilocalories (food calories).


The number of food calories is 895.2 food calories

= The differences between flowering and non - flowering plants are :

<h3 /><h3>Flowering plants </h3>

i) All flowering plants are green...

ii) Flowering plants produce flowers and seeds ...

iii) All flowering plants are multicellular..

iv) Flowering plants are more developed.

Examples: Cyas, pine ,pea, rose etc

<h3>Non-flowering plants </h3>

i) Non-flowering plants may be green or non green...

A diploid organism has a total of 60 chromosomes. Assuming all possible chromosome combinations are viable, a mutant nullisomic
elena-s [515]

Answer:

The formula is 2n - 2

Since n is 30

= 2(30) - 2

= 60 - 2

= 58

A mutant nullisomic version of this organism would have 58 chromosomes.

A diploid cell missing both copies of the same chromosome exhibits a nullisomic condition or a cell or individual with one chromosomal type missing. Humans having this condition will not live.
