Look online and find out what each muscle group does and what at least 5 muscles do and list that information.
Flexor Group-
Peroneal Group-
Hamstring Group-
Gluteal Group-
Quadricep Group-
Extensor Group-
Sartorius Group-
Adductor Group-
Answer:
Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.
Peroneal Group- these muscles play a role in the movements of the ankle joint and support of the foot.
Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.
Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.
Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.
Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris and extensor digiti minimi.
Sartorius Group- couldnt find anything
Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

Why does Dr. Giedd compare reading to the new flood of information that a child's brain must process today?
Answer:
He made this comparison because just as reading is a learned activity by the brain, so are the new flood of information that a child's brain must adapt to.
Explanation:
In describing the intricacies of the human brain, Dr. Jay Giedd talked about the brain's special ability to adapt to new behaviors as well as to multitask. Many of our ancestors lived and died without ever reading a book but humans alive today have adapted well to reading. So has the brain also adapted well to all the flood of information in our day.
The brain learns through examples and it does a good job at this. This is the more reason parents should endeavor to display good examples in the presence of their children.

Ecologists study both biotic and abiotic factors and how they interact. Therefore, ecologists often use methods and data from other areas of science, such as geology, geography, climatology, chemistry, and physics.
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals

Through geology and geography, we can study biotic and abiotic factors within an ecosystem.
How can you study biotic and abiotic factors within an ecosystem?The interactions between biotic factors, such as organisms like flora and fauna, and abiotic factors.
For example, all animals (biotic factors) breathe in oxygen (abiotic factor). All plants (biotic factor) absorb carbon dioxide (abiotic factor) and need water (abiotic factor) to survive.
Thus, geology and geography, are the two ways to study biotic and abiotic factors within an ecosystem.

A strand of RNA has the sequence AUUGCGCGAA. What explanation can be made about how this strand came to be?
A. The RNA strand formed from the rearrangement of the bases in a DNA strand.
B. The RNA strand broke off from a DNA strand that had a much longer genetic code.
C. The RNA strand was transcribed from a DNA strand with the sequence TAACGCCTT.
D. The RNA strand was translated from a DNA strand that had the sequence UAACGCCUU.
A strand of RNA with the sequence "AUUGCGCGAA" has been transcribed from a DNA strand with the sequence "TAACGCCTT". Thus, the correct option is C.
What is Transcription?Transcription is the process of formation of mRNA from the DNA in the nucleus of cell. The machinery involving all the enzymes and nucleotides are present in the nucleus for the development of mRNA. mRNA is the messenger RNA which is transcribed from DNA.
The sequence of mRNA formed from the DNA in a cell is complementary to the leading strand of the DNA in which only the thymine residues are replaced by the uracil residues. Adenine base pairs with uracil and thymine residues base pairs with adenine residues. Cytosine residues base pairs with guanine residues and vice versa.
Thus, the sequence of DNA from which mRNA has been synthesized is "TAACGCCTT".
Therefore, the correct option is C.

list 3 ways soils are classified
Answer:
Soils are composed of mixtures of mineral and organic materials, but are classified according to the size of their mineral particles. The three main texture groups are sandy, silty, and clay.
Sandy soil contains particles that can be seen with the naked eye and feels gritty when rubbed between the thumb and forefinger. Sandy soils will generally not stick together when wet.
Silty soil contains particles, which are smaller than sand particles but larger than clay particles. Silt feels powdery when rubbed between the thumb and forefinger. Silty soil sticks together when wet, but will not hold its shape after it is dry.
Clay soil contains the smallest particle size. Clay particles form a sticky soil when wet and will generally hold a shape after drying. Soils are rarely composed of just sand, silt, or clay. They are usually a mixture of the three with a larger percentage of one size of particles.
Answer:
Depending upon the average grain-size and the conditions under which soils are formed and deposited in their natural state, they may be categorized into following types on the basis of their structure: In the grain-size classification, soils are designated according to the grain-size or particle-size. The more common classification systems are enlisted below: Geological Classification
Classification by Structure
Classification based on Grain-size
Unified Soil Classification System
Preliminary Classification by soil types
Based on the agencies responsible for their present state, soils may be classified under following types: Residual Soils
Transported Soils:
Alluvial or sedimentary soils
Aeolian soils
Glacial soils
Lacustrine soils
Marine soils.
Then you have inorganic and organic soils.

A garden pea plant possesses one allele coded for yellow seed colour and one a coded for green seed colour. Which statement is true?
A green pea plant possesses one allele coded for yellow seed color and one a coded for green seed color. The true statement is the individual is heterozygous for the seed-color allele.
What are alleles?At a given genomic location, an allele is one of two or more variants of DNA sequence (a mono base or a segment of bases).
For any given genomic location where such variation exists, an individual inherits two alleles, one from each parent. If both alleles are identical, the person is similar for that allele.
Thus, the true statement is the individual is heterozygous for the seed-color allele.

If the AG of a reaction was -31.45 kJoules, you would know that:
A. the products have more free energy than the reactants.
B. the reaction requires an energy input of 31.45 kJoules to proceed.
C. the reaction most likely leads to development of a more ordered system
D. the reaction is spontaneous
Answer:
The correct answer is - option D. the reaction is spontaneous. (considering it as delta G or ΔG)
Explanation:
If a chemical reaction has a negative ∆G it means the reactants have more free energy than the products due to the fact that they give off some of their free energy during the reaction.
Such reactions release free energy and therefore called exergonic reactions. These reactions are also known as spontaneous reactions as they do not require energy to take place.
Thus, the correct answer is - option D.
