Answer:
The Struggle for Survival refers to the fight between organisms to survive by having access to the increasingly scarce resources in the environment brought upon by population increase.
Darwin believed that evolution was brought about by external pressures arising from this struggle for survival as species would have to adapt to the unique challenges in their environment to be able to better access resources.
This is why one must understand the challenges in an environment to understand why species in that environment evolved the way they did.

Abstract
Feeling connected to nature has been shown to be beneficial to wellbeing and pro-environmental behaviour. General nature contact and knowledge based activities are often used in an attempt to engage people with nature. However the specific routes to nature connectedness have not been examined systematically.

Define homeostasis and explain why it is important.
Homeostasis is the ability of an organism or system to maintain a stable internal environment despite changes in the external environment. The term was coined by Walter Bradford Cannon in 1930 and comes from the Greek words "homeo," meaning "similar," and "stasis," meaning "standing still."
Homeostasis applies to the body's physiological processes, such as metabolism, temperature regulation, fluid balance, and hormone secretion. These processes involve a series of feedback mechanisms that sense changes in the body and trigger responses to restore balance. For example, when the body's temperature rises above a certain level, thermoreceptors in the skin and hypothalamus signal the sweat glands to produce sweat and the blood vessels to dilate, which helps to dissipate heat and bring down the temperature.
Homeostasis also applies to psychological processes, such as mood, stress, and arousal. These processes involve the brain's regulatory systems, such as the limbic system, the autonomic nervous system, and the endocrine system. These systems work in tandem to respond to internal and external stimuli, and regulate emotions, instinctual drives, and cognitive processes.
The concept of homeostasis is important in understanding health and disease. When homeostasis is disrupted, the body or mind may experience dysfunction, disease, or pathology. For example, chronic stress can lead to an overactive HPA axis and the release of cortisol, which can suppress the immune system and lead to inflammation and disease. Diabetes is also a condition where the body's homeostasis is disrupted, resulting in high blood glucose levels and impaired glucose metabolism.

What might happen to your local hydrosphere and geosphere if conditions in the atmosphere caused rain for several weeks?
Answer:
the hydrosphere(bodies of water)would cause floods and other natural disasters while the geosphere will become infertile and landscape change (weathering).
Explanation:
The unit states that any animal that can be domesticated probably already has been. Explain the logic behind the statement and whether or not you find it convincing.
Answer:
Saying that if an animal can be domesticated that it probably already has been is saying that a lot of things are documented and if it has the capability to be domesticated or brought under human control then someone somewhere probably has. So I would personally find this convincing.

What is the role of energy in living organisms? Is ti a mor or less important role than other characteristics of life?
Answer:
A huge number of chemical reactions take place continuously in a living cell. The whole of all chemical processes, that is, the total turnover of matter and energy is called metabolism.
Explanation:
All organisms need the energy to grow, reproduce, and respond to their surroundings. All these processes are achieved through metabolism that allows the energy available to them.

3. Stratosphere :- The layer of atmosphere just above the troposphere where the temperature remains fairly constant.
4. Thermosphere :- The layer of atmosphere above the mesosphere where temperature are the highest in the atmosphere.
5. Ozonosphere :- Region in the upper stratosphere where the ozone is concentrated.
6. Aurora :- Streamers and band of light appearing in the sky at night , especially in polar region.

What is an organ system? Choose one of the organ systems and list the organs that belong to that system, as well as the system’s function.
Answer:
An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.
1 circulatory system.
Circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs and cells and carrying their waste products away.
Keeps the body's temperature in a safe range.
Answer:
There are ten major systems in the organ system.
One Example:
renal system, in humans, organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and voiding of urine.
Explanation:
A system is an organization of varying numbers and kinds of organs so arranged that together they can perform complex functions for the body. Ten major systems include the skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and the reproductive system.

1. Provide two examples of why coral reefs are important ecosystems on Earth.
2. Some corals in the warm pools off Ofu Island can withstand temperatures of 32° to 34 °C without bleaching. So, the researchers set up a controlled laboratory experiment to try to determine why these corals survive in such excessive heat. With regard to the experimental design, provide two reasons why Dr. Palumbi devised a standardized test for the corals.
Answer:
It provides shelter and protection.
Explanation:
Coral reefs are very important to our ecosystems on Earth because it provides shelter to a large population of ocean life and also provide protection to coastlines from strong ocean currents and high waves from causing damage. Dr. Palumbi devised a standardized test for the corals in order to find out that why coral reef can withstand temperatures of 32° to 34 °C without bleaching.

electrons are the electrons in the outer energy
level of an atom that can participate in interactions with other
atoms.
Check it
Answer:
Valence
Explanation:
In an atom, the electrons at the outermost energy level is called as valence electrons. It is the valence electrons which participates and interacts with the other atoms and form bonds. The valence electrons of an atoms are important as they depict the chemical properties of an element.
Thus the valence electrons resides the outermost shell and surrounds the atomic nucleus.
