Answer:
Explanation:
Okay so, The Energy pyramid is the pyramid and order which energy is used and recycled. At the top of the pyramid you have the Animals at the top of the food chain such as humans, lions, ect. At the bottom you'll have, of course, things at the bottom of the food chain such as grass. How it works is the grass turns the sunlight into energy, which the grass is then consumed by an insect such as a grasshopper. The energy that was given to the grass is now in the insect. The insect gets consumed by one of its hundreds of predators, which is then consumed by the superiors of the food chain such as ourselves. Then of course we die then that's where the decomposers come in. Just munching on your remains and converts into the energy for mushroom. Then it starts all over again.
The form of animal behavior that this prairie dog on guard duty exhibits is altruistic behavior.
This means that the dog isn't only thinking about itself, but rather about the others as well. Since it escaped danger, it alarmed other dogs as well, so that they could also be safe and not injured by the golden eagle. It seems that not only humans, but also animals are capable of showing such a behavior.
The question is incomplete as it does not have the options which are:
- Yes, because people's eyes move during sleep, and this stimulates the rods and cones.
- No, because rods and cones only convert light energy into electrical signals.
- No, because rods and cones never produce electrical signals.
- Yes, because the rods and cones are reproducing images that are then sent to the brain.
Answer:
No, because rods and cones only convert light energy into electrical signals.
Explanation:
The rod and cone cells are the photoreceptor cells present on the retina of the eye which receives the physical stimulus in the form of light and then converts the light energy into the electrical energy which is sent to the brain.
When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.
Thus, the selected options are correct.
Answer:
The process where part of the DNA is saved during replication is known as semi conservative replication.
Explanation:
During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid). When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus
of a cell during the s stage of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.
