Answer:
According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.
Explanation:
The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. <u>XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex</u>.
In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.
Answer:
2. It is made of sandstone which is very porous and is easily penetrated by rainwater
Explanation:
The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.
Answer:
There is no benefit to change this from happening
Explanation:
Typically elephants live until they are over sixty years old. At this age the teeth are worn down and become unusable; some of them may even fall out. When this happens the animal finds it difficult to acquire nutrients and typically becomes malnourished. The animal slowly starves to death and eventually leaves the herd.
There is no reason for this to change from an evolutionary stand point because this animal has already contributed to the herd as a younger elephant. If the older animals continue to live longer this will slow down the movement of the herd as well as consume the resources that the younger elephants need to keep strong and resist predation.
The sick elephants leave the herd and go to the elephant grave yard to pass away and allow the herd to move on.
I believe your answer is erosion
You want to find pounds of CO2 / week = lb CO2 / week
1 lb CO2 2 gal gas 144 * 10^6 car 7day
------------- x --------------- x ------------------ x ---------
1 gal gas car day week
Check what happen with units
lbCO2 gal car day
----------- x ------ x ------ x ------- = lb CO2 / week
gal car day week
So the result is 2 * 144 * 10^6 * 7 lb CO2 / week = 2,016 - 10^6 lb CO2 / week
Answer: 2,016 millions of pounds of CO2 per week.
