Answer: I think the answer is true
Explanation: If you think about it, the terrestial planets ( being venus, earth, mars, and mercury) are made up very little gas which are carbon dioxide, nitrogen and oxygen, and the gas giants ( being jupiter, saturn, neptune, and uranus) have gases such as hydrogen and helium. Thus meaning, the terrestial planets could be a part of it and the gas giants are the most. So yes, the answer is true.
Answer: The average speed of the toy car during the two trials is 2m/s.
Explanation:
Speed can be defined as a type of scalar quantity in physics through which the rate at which an object travels through a distance is measured in a given amount of time. The formula for determining the speed of a car is:
Speed= distance/ time which has an SI unit of m/s.
From the speed tests carried out on a toy car, the speed of trial 1 is:
Distance= 10 meters
Time= 5 seconds
Therefore trial one speed is 10/5= 2m/s
While the speed of trial 2 is:
Distance= 40meters
Time= 20 seconds
Therefore trial 2 speed is 40/ 20= 2mls
Average speed of the toy car during the two trials is: Sum of both both speeds divided by total number of trials.
Therefore: 2 m/s + 2m/s / 2= 2m/s
From the calculation, the average speed of the toy car during the two trials is 2m/s.
Recombinant DNA innovation gave an approach to researchers to create human insulin in the lab. The quality for human insulin is disengaged from human cells and embedded into plasmids. These plasmids are then brought into bacterial cells, which produce the insulin protein in view of the human code.
Recombinant DNA are currently used for all of the above (d).
Answer:
B. Sulfur
Explanation:
Acid rain is <u>the result of sulfur dioxide emissions combined with nitroxen oxides.</u> This occurs when both compounds interact with water and oxygen (and other molecules) that are already present in the atmosphere.
This phenomenon is extremely dangerous for both humans, fauna, and flora, especially when it comes to aquatic organisms. <u>Some freshwater fish species, for instance, are not able to grow or develop due to the increased pH. In other cases, when the pH is even lower, organisms are not able to cope and eventually die.</u>
Therefore, a reduction in atmospheric concentrations of sulfure could reduce acid rain and return rain to its normal pH.
True statements are
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom.
In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation:
Diploblastic animals (radially symmetric animals like jelly fish, sea anemone) has only two layers – the endoderm and the ectoderm. It does not have mesoderm germ layer. Diploblastic animals are formed from the embryonic process called gastrulation from a blastula cells.
A true coelom and pseudocoelom may differ in their structure or location but their main function is the same. Since both are fluid-filled cavities, they act as hydrostatic skeleton disseminating extra pressure via the body to protect the internal organs and minimize damage.
Each germ layer gives rise to tissues pertaining to a particular organ or organ system. Like the mesoderm provides for muscles, nervous system and the endoderm gives rise to gastrointestinal organs, lungs etc. So the tissues lining outside and inside the body cavity will arise from the same germ layer.
