Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Which scenario describes an interaction between two of Earth’s spheres?
Water flows from a stream to a lake.
Gravity moves rocks to another location.
Lions use energy to catch other animals for food.
Bears dig big holes in the ground to protect their young.
Answer:
The scenario that describes an interaction between two of Earth's spheres is "bears dig big holes in the ground to protect their young".
Explanation:
The Earth spheres include the biosphere, the hydrosphere, the geosphere, and the atmosphere. In this context, there is an interaction between two spheres: the biosphere and the geosphere, when a bear digs holes in the ground because a living organism that is part of the biosphere is modifying the structure and shape of superficial soil, which is part of the geosphere.

C. crushing and milling
D. drilling and blasting
Answer:
C
Explanation:
Here is a diagram of the digestive system. Where do you think lactase would be most effective? Explain. Be sure to consider the amount of time lactose/food would spend in each area.
Lactase will most likely be found in the small intestine and food spends the largest time there.
The digestive system refers to all the structures that are responsible for the breakdown of food in the body. In each part of the digestive system, enzymes act on the food particles to enable certain conversions.
The enzyme lactase in involved in the digestion of milk and diary products. The enzyme has an optimum pH of about 6 hence it works in an acidic environment. Lactase is found in the small intestine.

the group of cells that use chemicals to recycle elements in the blood are called
a.muscles
b.glands
c.hormones
d.oxygen
Explanation:
I'm guessing the answer is oxygen.
The oxygen cells are a type of cell that uses chemicals to recycle elements in the blood.
What is oxygen cells?Red blood cells, also known as erythrocytes, transport oxygen to your body's tissues. Your tissues emit carbon dioxide as oxygen is converted into energy. Red blood cells also transport carbon dioxide to your lungs for exhalation. Cells require oxygen to efficiently use glucose in cellular respiration. This is how most organisms obtain energy. When oxygen binds to parts of glucose molecules, water, carbon dioxide, and energy are released. After all, the organism uses the energy to create adenosine triphosphate (ATP). A type of blood cell found in the blood that is produced in the bone marrow.To learn more about oxygen cells, refer to:

Which adaptation is common to animals that live in temperate grasslands?
structures to dig burrows
keen eyesight to help them see in the evening
a thick insulating layer of fat
large ears to regulate body temperature
Answer:
This is 100% right.
Explanation:
Temperate grasslands are characterized by vast expanses of open grasslands with few trees and shrubs, so structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is preset in the first option.
What are temperate grasslands?Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.
Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.
