Why is humus important?
A) It increases soil porosity.
B) It decreases soil acidity.
C) It increases soil basicity.
D) It decreases water movement.
Answer:
D) It decreases water movement.
Explanation:
Humus is known as part of the soil formation. It is characterized by various qualities some of which include containing nutrients such as nitrogen. It is also characterized by its ability to retain water content or soil moisture. Humus is made from the decays of plants wastes such as leaves.
Hence, in this case, the correct answer is Humus is important because "It decreases water movement."

as cells undergo cellular respiration, what products are produced, and how are they released from the body
Answer:
The cells reproduce The products of cellular respiration are carbon dioxide and water. Carbon dioxide and there released by being transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled
Explanation:
Hope this helped :D
The products that are produced during cellular respiration are carbon dioxide and water. It uses oxygen as a reactant.
Cellular respiration:The process by which organisms take up oxygen and glucose as food molecules and then convert the energy for various activities leads to the formation of waste products like carbon dioxide and water.
This process breaks down sugar in the presence of oxygen to release energy.

Explain how gravity affects a plant's growth. pls
Answer:
Plants respond directly to Earth's gravitational attraction, and also to light. Stems grow upward, or away from the center of Earth, and towards light. ... Plants' growth response to gravity is known as gravitropism; the growth response to light is phototropism. Both tropisms are controlled by plant growth hormones.

Which of the following is a true statement about the rock cycle?
a
Sedimentary rock can revert to metamorphic rock but never to igneous rock
b
Weathering occurs in igneous rocks but never in sedimentary or metamorphic rocks
c
Heat, pressure, cooling, weathering, erosion and deposition change rock
d
The formation of rock within the rock cycle ends after metamorphic rocks form
Answer:
A.
Explanation:
becuase when the cycle occurs sediments make sedimatary rock and sedimetary rock after heat and pressure it make metamorphic rock not igneous rock.
Statement which is true about rock cycle is that sedimentary rock can revert to metamorphic rock but never to igneous rock.
What are sedimentary rocks?They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

EXPLAIN How might you use engineering, either by designing a device or process,
to help reduce the impact of human activity on a local species?
A microwave absorbing device can be created to absorb the microwaves in the air from the communication signal plant or lines.
Cell phones or towers of cell communication, or towers can emit a frequency of 900 to 1800 MHz microwaves which are responsible for negatively affecting the health of birds.This have been proved that it can cause thinning of the skulls of the chicks and thinning of their egg shells which can reduce the population of local bird species. Thus the development of microwave absorbing device can help in reducing the negative influence of microwaves on bird species population.Learn more about microwaves:

What is the percent by volume of a solution formed by adding 15 L of acetone to 28 L of water?
Answer:
34.88 %
Explanation:
To solve this question, we are going to assume that the acetone has 100% solution.
We know that 15 L of acetone was added to 28 L of water
We need to determine the percent by volume of a solution as
15 L of acetone/ (15L of acetone +28L of water)
= 15L/43L
=0.3488
= (0.3488×100%)
= 34.88 %
Hence, the percent by volume of a solution formed is 34.88

Explain the two reasons why DNA changes
Answer:
1.) Mutation or outside effect
2.) The DNA copies itself
Explanation:
1.) Mutations can occur when a body is exposed to high amounts of radiation or other harmful chemicals, thus changing the DNA.
2.) In order for our bodies to grow, cells must divide and make new cells. Each time a cell makes new cells, the DNA has to copy itself for the new cell. This process is called “replication.”

in a tropical forest the trees often grow very closely together, which reduces the amount of light reaching the forest floor. the seeds of many species will not germinate unless they get plenty of light. Suggest why this is an advantage to the seedlings. someone answer this plssss
Answer:
Explanation:
The seedlings gaining sunlight will help them be able to grow and go through photosynthesis as they are able to gain sunlight which they need
In a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.
What are the best conditions for seedling growth?Many factors are required for seedlings to grow, such as proper sunlight, wind, fertile soil, and so on, here seedlings that are present in dense forest that rarely get sunlight never grow, but those that do grow get sunlight, and because they are present in dense forest, there is less transpiration from lower plants.
Hence, in a tropical forest, the trees often grow very closely together, which reduces the amount of light reaching the forest floor and seeds of many species will not germinate unless they get plenty of light so that they can do photosynthesis and grow.

Frost wedging is a type of:
-Biochemical weathering
-Physical weathering
-Chemical weathering
-Biological weathering
Answer: Physical Weathering
Explanation:
It is physical weathering because it is the action of water going into cracks and thawing it causing the rock to break. This is a natural way of breaking it, not a chemical reaction way of breaking the rock, so it is physical :)

1.turmeric red
2.purple cabbage juice green
3.red litmus blue
4.all of the above
Answer:
D) all of the above
Explanation:
Turmeric, purple cabbage juice (containing anthocyanin), and litmus paper all act as indicators which help us to detect whether a particular substance is acidic or basic.
In basic medium, turmeric changes it's colour to red, purple-cabbage juice turns to green and red litmus turns to blue.
Baking soda/Sodium carbonate Na
is basic in nature and thus causes the above changes in the indicators.

Explain coding DNA vs noncoding DNA
Answer:
Non-coding DNA sequences are components of an organism's DNA that do not encode protein sequences. Some non-coding DNA is transcribed into functional non-coding RNA molecules (e.g. transfer RNA, ribosomal RNA, and regulatory RNAs). ... Since that time, this non-functional portion has controversially been called "junk DNA".

Answer:
No.
Explanation:
Big cat hybrids are not real species, For animals to be a species, they need to give birth to successful offspring, who can reproduce themselves. For big cat hybrids, this will not happen as male ligers are sterile, and females are not always able to reproduce
Answer:
its not
Explanation:
question: Is a liger considered a species? Explain why or why not.
The liger is a hybrid cross between a male lion and a female tiger; both are in the genus Panthera but of the species leo and tigris respectively. Ligers exist only in captivity because the habitats of the parental species do not overlap in the wild.
