Answer:
<em>The statement that is incorrect is :</em>
<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>
Explanation:
A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.
Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
Ligaments connect one bone to another bone. Therefore, they allow a joint to form, because joints are where two or more bones connect.
Take your knee joint for instance (***see attached pic***). The knee joint is formed by the connection of the femur (your thigh bone), the tibia (your shin bone), and the fibula (the other long bone in your lower leg). In order for all of these bones to connect there are many ligaments in the knee joint that keep the bones connected and in place. A well known example of one of these ligaments in the knee joint is the ACL (anterior crucate ligament), which is commonly torn in sports, namely football. Most people have heard of this ligament because it receives a lot of media attention since tearing it can greatly alter or even end professional athletes' careers.
Answer:
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.
A random change in the DNA that could provide the offspring with an adaptation to increase its chances of survival is Mutation.
<u>Explanation:</u>
Mutations are modifications to an organism’s DNA that generate a difference within a group by including distinct alleles. Adaptations are physical or behavioral features that deliver an organism completely adapted to its surroundings.
A mutation is a variation in a DNA sequence. Mutations can happen from DNA copying errors made while cell division, presentation to ionizing radiation, exposure to chemicals called mutagens. Germline mutations happen in the eggs and sperm and can be carried on to offspring, while bodily mutations transpire in body cells and are not carried on.
Layers 2 and 9 are the same age.
Faulting created the differences in layers.
