Answer:
DNA can be described as the molecules which carries the genetic code for every individual. The DNA is made up of nucleotide bases which join the two strands of DNA. The sugar and phosphate form the backbone of the DNA.
Genes are the hereditary molecules which are made up of DNA. The alleles of a gene represent which traits will be carried by an organism.
Chromosomes are made up of genes. During reproduction, crossing over of DNA occurs and alleles of the genes assort independently due to which variations occur.
Answer:
Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.
<u>Phyletic</u><u> </u><u>gradualism</u> - slow, but constant gradual change; supported by transitional species in the fossil record
<u>Punctuated</u><u> </u><u>equilibrium</u>- long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found.
Answer:
uplift
Explanation:
this process is called uplift and it can cause rocks that were once underground to come up above the earth's surface. once these rocks are moved the surface , they begin to weather and erode and you know what happens after that.
I hope this helps. let me know and if not I'll try and help you again. have a blessed day
I may not be able to make you a presentation, but I can help you on the idea behind it. Photosynthesis is 6 Carbon dioxide 6 water and light to make glucose and oxygen. With cellular respiration, its the opposite. Glucose + oxygen to break it down and forms waste products of 6 carbon dioxide and 6 water. The main thing it produces though is ATP (Adenosine Triphosphate). ATP is the product of cellular respiration and is fuel for your cells to function. I hope this helps. There are different stages in photosynthesis and cellular respiration that I’m not going to dive into, but this is the main reason why they depend on each other. Because unlike humans where we eat food, they use photosynthesis to make their glucose which they turn into ATP energy. Think I covered most of it. Good luck on your presentation!
