Answer is A
Explanation:
In the past, conservationists were concerned with leaving the environment in a better state than the condition he or she found it. The contemporary environmentalism movement, on the other hand, increasingly seems to view humankind as an inherently intrusive interloper upon nature.
what things can be determined from a cross-section of a tree trunk?
Answer:
A cross-section of a tree trunk, also known as a tree cookie or tree round, can provide various pieces of information, including:
Age of the tree: The number of growth rings in the cross-section can be counted to determine the age of the tree.
Growth patterns: The thickness and width of the growth rings can provide information about the growth patterns of the tree, including periods of rapid and slow growth.
Environmental conditions: The width and color of the growth rings can also provide information about the environmental conditions the tree experienced during its life, such as droughts, fires, or disease.
Wood type: The type of wood and its density can be identified from the cross-section, which can help in determining the species of the tree.
Health and vitality: The appearance of the wood, such as cracks, decay, or insect damage, can provide information about the health and vitality of the tree.
Historical events: In some cases, the cross-section may also contain evidence of historical events, such as bullet holes, carvings, or scars left by fires or lightning strikes.
Overall, a cross-section of a tree trunk can provide valuable information about the history, growth patterns, and environmental conditions of a tree, and can be used by scientists, researchers, and arborists to better understand and manage forest ecosystems.
Answer: Tree trunk thoughts
Explanation:
Knowing that you have a tree that is "cross-section" of a tree, there are severl but the most common reasons are, disastrous floods, insect attacks, lightning strikes, and even earthquakes. These can be reason of this question.

Explanation:
Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share a common ancestor population that lived about 250 million years ago, but they have been separated in different environments, with different food sources, for millions of years. Komodo dragons and red-tailed boas have some shared structures. They also have some differences in their structures.
1.Why do Komodo dragons and red-tailed boas have some shared structures and some different structures?
Komodo dragons and red-tailed boas have some shared structures because they both evolved from a common ancestor population that lived about 250 million years ago.
What is the difference has come over the time in these species?Over time, as these two species separated into different environments with different food sources, they underwent separate evolutionary trajectories that led to differences in their structures. However, many of the underlying genetic and developmental mechanisms that produced their ancestral structures are still present in both species.
For example, both Komodo dragons and red-tailed boas have scales, which are a common feature of reptiles. Scales serve to protect the skin from abrasion and injury, as well as to reduce water loss. They also both have a vertebral column, which provides support for the body and protects the spinal cord.
At the same time, Komodo dragons and red-tailed boas have differences in their structures because they evolved in different environments and have different feeding strategies. Komodo dragons are large, carnivorous lizards that use their sharp teeth and powerful jaws to hunt and kill prey, while red-tailed boas are constrictor snakes that use their muscular bodies to suffocate and swallow their prey whole.
As a result, the structures of their jaws, teeth, and digestive systems are adapted to their respective diets and hunting strategies, and differ in significant ways.
Overall, the shared and different structures between Komodo dragons and red-tailed boas reflect both their common evolutionary heritage and their divergent evolutionary trajectories.

What reasons do people have outside science to think that a theory is incorrect? And would their scientific arguments be valid?
Answer:
A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like hypotheses. And theories are continually improved or modified as more information is gathered, so that the accuracy of the prediction becomes greater over time
Answer:
As with hypotheses, scientific theories can also be tested or rejected, just like hypotheses, even after being proven or disproved through the use of scientific methods.

Read the following excerpt and answer the question:
Emilie Dressaire, professor at Trinity College (Hartford, CT), and her colleague Marcus Roper (UCLA) discovered that mushrooms create their own microclimates. They create their own moisture through evaporation, which is when a liquid turns into a gas. Heat energy is used in this process, leaving the mushrooms cool and moist.
Use your own words to summarize the effect of thermal energy on a mushroom's environment and how this sustains life. (4 points)
Answer:
Mushrooms can reproduce by using thermal energy to create conventional currents, which are known as pockets. Following the formation of the pockets, the currents disperse microscopic spores in the surrounding air. As a result of the spread, a large spore cloud forms, which is visible at night.

Photosynthesis is to oxygen as:
A. Oxygen is to carbon dioxide
B. Cellular respiration is to carbon dioxide
C. Cellular respiration is to oxygen
D. Cellular respiration is to enzymes
Answer: It is C but if it was multiple choice it would be both B and C.
Explanation: Allow me to explain my reasoning. During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). And allow me to explain the answer C. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Therefore, it can be both B and C if it was multiple choice. Thank you for your time.
Photosynthesis is to oxygen as Cellular respiration is to carbon dioxide. Thus option B is correct.
what is photosynthesis ?The process in which sunlight energy is used by plants, algae and certain bacteria convert them into chemical energy and starch called as photosynthesis.
Photosynthesis occur in chloroplast which has its own DNA, genes and hence can synthesize their own proteins, photosynthestic Pigments responsible for trapping sunlight present in chlorophyll pigment of chloroplast, like chlorophyll a, b and c.
Bacteria also have chlorophyll known as bacteriochlorophyll can absorb infrared rays, other pigments are Carotenoids which are yellow, orange or red-coloured pigments that absorb bluish-green light., Xanthophyll, Phycobilins.
plastids are found in the cytoplasm of eukaryotic photosynthetic organisms. They contain pigments and store nutrients. Plastids are of three types such as Leucoplast, Chromoplasts, Chloroplasts
Antennae is made up of 100 to 5000 pigment molecules that capture light energy from the sun in the form of photons, Reaction Centers where photosynthesis occur.
