Aleksandr [31]
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels over time by not allowing water to INFILTRATE. 

Greenhouse gases (GHGs) are gaseous components that absorb the infrared radiation emitted by the earth's surface and contribute to the greenhouse effect. The increase in their concentration in the Earth's atmosphere is one of the factors causing global warming.

Concrete does not allow water from the ground surface to infiltrate to underground.

If all the macromolecules are made mainly of the elements CHO, how are they different?
Elanso [62]
The four main classes of organic compounds (carbohydrates, lipids, proteins, and nucleic acids) that are essential to the proper functioning of all living things are known as polymers or macromolecules. All of these compounds are built primarily of carbon, hydrogen, and oxygen but in different ratios. This gives each compound different properties. Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called nionosaccharides. Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio. Monosaccharides or simple sugars include glucose, galactose, and fructose. Although their chemical formulas are the same, they have different structural formulas. These simple sugars combine to make disaccharides (double sugars like sucrose) and polysaccharides (long chains like cellulose, chitin, and glycogen). Color code the glucose molecule on this worksheet (carbon-black, hydrogenyellow, and oxygen-red). Use your textbook to help draw the structural formulas for fructose and galactose:

Land-based plants must have mechanisms to disperse and scatter their seeds so that new plants don't grow in the shadow of old pl
katen-ka-za [31]

Answer:

Its c ,animals ,seed wings and wind

Explanation:

There are mainly 2 ways the seeds of gymnosperms are dispersed :-

  1. The gymnosperms that are old become rip and their cones open up and the seeds are dispersed by the wind.There are small seed wings present on seeds that take the seed to long distance places
  2. The fruit of the gymnosperms gets eaten by the animals in different places as its their source of food .The seeds are not digested by the animals and excreted as a result the seed is dispersed far away from the source

George on one pair of his chromosomes has STRs of lengths 6 and 7, Stephen (his father) STRs of lengths 3 and 6, and Mary (his m
JulijaS [17]

Answer:

Stephen is not his biological father.

Explanation:

DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.

The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.

Thus, the correct answer is option (a).
