Answer:
paleoclimatologists use different sources of information from fossils in order to record past climate and environmental conditions (for example, tree rings or skeletons of coral reefs)
Explanation:
Paleoclimatology is the discipline that studies ancient climate and environmental conditions. Paleoclimatologists are researchers that analyze different sources of evidence to obtain accurate records of past climate conditions. In this regard, the fossil record has proven to be a useful tool to obtain such information. For example, the rings of fossilized trees are usually wider during warm and wet years, while these rings become thinner during cold and dry years. Moreover, geochemical records from the skeletons of fossil corals (composed of calcium carbonate) are good indicators of past climate conditions because coral growth is sensitive to small fluctuations in water temperature. Paleoclimatologists also use non-biological climate indicators (e.g., sediments and ice sheets) to reconstruct past climate and environmental conditions.
Answer:
Explanation:
The two categories of the behavior includes the operant behavior and respondent behavior.
Operant behavior: The operant behavior can be define as the behavior that is under the control of the consequences. These consequences are likely to control the future frequency of behavior. For example, A child who is allowed to hit other children and take their toy, is likely to be aggressive to other people in the future.
Respondent Behavior: The behavior which is under the influence of a specific stimuli is a respondent behavior. For example, Snapping of hand away from a hot pan, and Salivation of the mouth due to food.
Answer:
Organs are made of different kinds of tissues that work together.
Explanation:
All the organs are made of tissues, the organ level is the next level up from tissues. The groups of tissues work together. The tissues are specialized cell group, the animal body is made of 4 types of tissues: epithelial, connective, muscle, nervous.
Organs and tissues are levels of organization. Organs are structures made up of two or more tissues, together they carry out a particular function.
A cell can also use energy to move a large substance or a large amount of a substance in vesicles.
Answer:
Vascular tissue is a complex conducting tissue found in vascular plants that is made up of several cell types. The xylem and phloem are the two main components of vascular tissue. Internally, these two tissues carry fluid and nutrients.
