How do tree rings and ice cores help scientists understand how earth has changed over time

Biology
1 answer:
Alex787 [66]3 years ago
6 0
The study of tree rings is called dendrochronology. Trees produce a single growth ring each year and by studying the size and composition of each ring scientists can get information about the age of the tree, available nutrients in the area, and general climatic conditions. A relatively small ring may indicate a year when there was very little rainfall and a larger ring indicates favourable conditions for plant growth. 

Ice cores hold information on past global volcanic activity and past atmospheric conditions. Tiny bubbles in the ice cores give information on the concentration of gases in the atmosphere. Ice core data plays a key role in linking the increase in carbon dioxide concentrations to present day global warming.

How is volume, temperature, pressure and density of gas related
ollegr [7]

Boyle's law states that, at a constant temperature, the volume of a given mass of gas varies inversely with pressure. ... Thus Charles's law states that at a constant pressure, the volume of a given mass of gas is directly proportional to its (absolute) temperature. hope this helps

Be able to describe the structures and functions of these systems and how they work together:
san4es73 [151]

The nervous system: In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.

The circulatory system: The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

The respiratory system: The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.

The muscular system: The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture and circulates blood throughout the body. The muscular systems in vertebrates are controlled through the nervous system although some muscles can be completely autonomous.

Hope this helps!!! if so please give brainliest

Indicate whether the following outcomes of cell division are observed in mitosis only, meiosis only, or both mitosis and meiosis
serious [3.7K]

Answer:

A. Both in mitosis and meiosis (II)

B. Mitosis

C. In both

D. Meiosis

E. Mitosis

Explanation:

Prior to every case of cell division in both mitosis and meiosis, the cell always ensures to duplicates its contents including its chromosomes. In both cases of cell division, the sister chromatids separates, apart from in meiosis I where homologous chromosomes separates to opposite poles. Only one cellular division occurs in mitosis which is involved in the growth and development of the diploid individual but in meiosis, two divisions takes place in the gametes (both male and female) to ensure that the haploid number of chromosomes is transfered from both parents each to the offspring ensuring a constant diploid offspring. Thus a diploid parent cell always produces a haploid daughter cell in the gametes during meiosis. In mitosis, the daughter cells are always identical to the parents cells.
