Which statements about humus are true? Choose more than one
answer
It forms from dead plants
It collects in bedrock
It fertilizes soil
It contains carbon
It is only found in topsoil
It erodes the rocks in soil
It forms from dead plants
It fertilizes soil
It contains carbon
It is only found in topsoil (not sure abt this tho)
Humus forms from dead plants, fertilizes soil, contains carbon, and is only found in topsoil. The correct options are A, C, D, and E.
What is humus?When plant and animal debris decomposes in the soil, humus, a black, organic substance, is created.
Plants scatter leaves, twigs, and other debris to the ground, which accumulates. Leaf litter is the name of this substance. Animal carcasses contribute to the litter after they pass away.
Humus is a form of soil produced by decomposing organisms and plants.
The name was developed by a French soil expert named Muller and is based on the Latin word "soil". Humus is challenging to define and is still not completely understood.
Only found in topsoil, humus is a material that develops from dead plants, fertilizes the soil, and contains carbon.
Thus, the correct options are A, C, D, and E.

Explanation:
22. An individual who participates in a long-distance run on a hot day will produce large
quantities of sweat. As a result of the excessive sweating, the amount of urine
produced by the kidneys will change.
How will the kidneys respond to help the individual's body maintain homeostasis?
The kidneys will decrease urine production so the body can maintain blood pH and allow the body to cool by excessive sweating.
What is Homeostasis?
Homeostasis refers to an organism's ability to regulate various physiological processes to keep internal states steady and balanced.
When an individual is running long-distance on a hot day will produce a large quantity of sweat. The kidney plays an important role here to retain the amount of urine and excessive sweat is produced to maintain the temperature of the body as well as the pH of the blood.
Therefore, the kidneys will decrease urine production so the body can maintain blood pH and allow the body to cool by excessive sweating.

A number of major evolutionary innovations arose in the fish lineage. Check all of the evolutionary innovations associated with the fishes.
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
c) Fish fins are ancestral (homologous) structures to the flippers (forelimbs) of turtles.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
e) The swim bladder ultimately led to the evolution of the amphibian urinary bladder.
Answer:
a) Teeth arose from the rough scales of ancestral sharks.
b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.

what are 5 examples that the muscles are working in pairs
Answer:
Muscles that work like this are called antagonistic pairs. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens.
...
Antagonistic muscle pairs.
Biceps Triceps
Hamstrings Quadriceps
Gluteus maximus Hip flexors
Gastrocnemius Tibialis anterior
Pectoralis major Latissimus dorsi
Answer:
Muscles that work like this are called antagonistic pairs.In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.For example, when you perform a bicep curl, the biceps will be the agonist as it contracts to produce the movement, while the triceps will be the antagonist as it relaxes to allow the movement to occur.The biceps contracts and raises the forearm as the triceps relaxesAntagonistic muscle pairs
The following groups of muscles are antagonistic pairs:Biceps
Triceps
Hamstrings
Quadriceps
Gluteus maximus
Hip flexors
Gastrocnemius
Tibialis anterior
Pectoralis major
Latissimus dorsi
To allow antagonistic pairs to work efficiently, other muscles called fixators assist by supporting and stabilising the joint and the rest of the body. Some fixators also assist the agonist and act as a synergist.The trapezius muscle can act as a fixator when the biceps is flexing the elbow joint.The abdominals can act as fixators to stabilise the body for hip and knee movements.Consider the path that blood takes through the heart and put the following locations in the correct order.

A scientist helps a colleague do a better experiment by:
O A. laughing when a common and avoidable mistake is repeated.
B. offering advice about how best to perform a standard procedure.
C. explaining why a hypothesis does not need to be tested in an
experiment.
D. refusing to allow anyone else to use an expensive instrument.
Answer:
B. Offering advice about how best to perform a standard procedure.
Explanation:
Helping others can be in different ways, be it helping out or by giving encouraging words or advice. But in all aspects of help, there is always a positive outcome if help is given in the right way and at the right time. And it is also how one person lifts another.
A scientist can help a colleague out by offering advice and telling the person how to best perform a standard procedure. This will help the colleague do better in the experiment and also help ensure that the right things are done and the efforts are successful. The other options are all negative in their 'approach' which will only hinder the colleague in his/her works.
Thus, the correct answer is option B.
Answer:Offering advice about how best to perform a standard procedure.

What is the process consumers use to release energy from food?
Answer:
Primary producers—plants, algae, and bacteria—make up the base of the pyramid, the first trophic level. Through a process called photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.

What is photosynthesis?
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide.
When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Thus, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.
