Answer:
probably tectonic plates would shift
Answer:
scientist has brought together all the research on the subject and found that, from bees to birds to wolves, many animals have an ability to process and represent numbers arguably a form of counting.
Explanation: What's more, the new study suggests that this mathematical prowess helps animals stay alive in a brutal world. Such a finding extends our knowledge of animal cognition, a field that has grown exponentially in recent years.
Think of it like this. Horses do a LOT of galloping, which is hard on the feet! Hooves are a physical ADAPTATION, so that the horses won't experience pain on their journeys. They're hard, so that the horses don't feel the ground nearly as much. Now, mountain goats travel over rough terrain, with sharp rocks and steep inclines. Again, it's really easy for them to get hurt strutting around the mountains, so they evolved hard hooves to protect their feet.
It is in vitro fertilization (IVF).
IVF is a type of assisted reproductive technology used for infertility treatment. It includes the steps like removing an ovum from the woman's ovaries, fertilisation (sperm cell from is injected using a microscopic needle, directly into each harvested ovum from the woman) outside the body, embryo transfer to the same or another woman's uterus after a few days.
A) DNA fulfils all three conditions:
<span>(1) copy itself precisely - in the process of replication, DNA copies itself and two molecules of DNA are formed. This process is very precise thanks to the great number of proteins involved in these process that prevents error occurring and proteins that can fix the error if it occurs.
(2) be stable but able to be changed - DNA is very stable molecule otherwise, it cannot be a genetic material. However, its chains can separate in a short length so the translational machinery can attach to it and the process of transcription can occur. Also, in crossing over, during meiosis, </span>the exchange of genetic material occurs and chromosomes change a bit.<span>
(3) be complex enough to determine the organism’s phenotype - it contains a number of genes responsible for different traits. All of this results in the </span>organism’s phenotype.
B) DNA copies itself. <span>Meselson and Stahl conducted the experiments on DNA replication in which they used </span>E. coli<span> bacteria as a model system. After they labelled all bacteria's DNA with heavy 15N by using medium with heavy 15N, they switched bacteria to medium with light 14N. After several generations, all bacteria's DNA was labelled with light 14N. This experiment evidenced that the self-replication of DNA is semi-conservative process.</span>
