2. In dogs, there is an hereditary deafness caused by a recessive gene, "d." A kennelowner has a male dog that she wants to use for breeding purposes if possible. The dogcan hear, so the owner knows his genotype is either DD or Dd. If the dog's genotype isDd, the owner does not wish to use him for breeding so that the deafness gene will notbe passed on. This can be tested by breeding the dog to a deaf female (dd). Draw thePunnett squares to illustrate these two possible crosses. In each case, whatpercentage/how many of the offspring would be expected to be hearing? deaf? Howcould you tell the genotype of this male dog? Also, using Punnett square(s), show howtwo hearing dogs could produce deaf offspring.

What is evidence that scientist use to support the big bang theory ?

Answers

The Big Bang theory is among the most widely accepted today to explain the origin of the universe. It holds that the universe emerged from the explosion of a single particle - the primordial atom - causing an unparalleled cosmic cataclysm about 13.8 billion years ago. The same theory further states that the universe is continually expanding.  The main evidence for the big bang theory is:

  • The galaxies to get further and further from us. This distance is taken at high speeds. In short, the spacing velocity of the galaxies is proportional to the distance these galaxies actually are. This evidence is called the "Hubble Law" and explains that our impression of galaxy dysthanization occurs because the universe is still expanding, and this theory further explains that the universe has already been connected.
  • The big bang theory states that the universe was already very hot, if this is true, we should find some evidence of this temperature. Well, this evidence was found when radio astronomers realized that there was cosmic background radiation in a microwave that had a temperature of 2,725 degrees Kelvin. This radiation is likely to be evidence of the high temperature the universe had.
  • Finally, the abundance of hydrogen and helium elements probably resulted from the Big Bang.

One big observational evidence that scientists have is the Cosmic Microwave Background Radiation (CMBR). This evidence is the most accurate because astronomers have claimed that the universe is evolving a set amount of matter and energy while it is expanding over time.

Could a balanced ecosystem contain producers and consumers but not decomposers? Why or why not.

Answers

I believe the answer is "no" because decomposers are the ones who recycle everything. If they didn't break down dead organisms, there could be catastrophe.

The structures that an animal uses to exchange gases with its surroundings make up theA. digestive system
B. respiratory system
C. excretory system
D. circulatory system

Answers

B. Respiratory system. I hope this wasn't too late!
The structures that an animal uses to exchange gases with its surrounding makes up the respiratory system. This is because respiration deals with the exchange of gases in and out of the body. And since the structures are for exchange of gases, then they are related to respiration. So the answer is B. Hope i helped.

How is the core, mantle. plate tectonics, and convection currents related?

Answers

The core, mantle, and plate tectonics are all related because they are all factors of the Earth

Answer:

Convection happens when particles with a great deal of warmth vitality in a fluid or gas move and replace particles with less warmth vitality.  

Lighter (less thick), warm material ascents while heavier (progressively thick) cool material sinks. It is this development that makes course examples known as convection flows in the environment, in water, and in the mantle of Earth.  

Huge amount of pressure and heat inside the earth causes the hot magma to stream in convection ebbs and flows. These flows cause the development of the structural plates that make up the world's outside.  

Plates at our planet's surface move in view of the extreme warmth in the Earth's center that causes liquid shake in the mantle layer to move.

It moves in an example considered a convection cell that structures when warm material ascents, cools, and in the long run sink down. As the chilled material sinks off, it is warmed and rises once more.
