Answer:
The atmosphere blocks out harmful rays from the sun. The ozone layer, which lies in the stratosphere 11 to 50 kilometers from the Earth's surface, blocks out many harmful forms of radiation. Without the ozone layer, ultraviolet rays would destroy most life on Earth. Gases in the atmosphere also hold in heat.

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.

Imagine you are a forensic investigator giving a presentation to a school assembly. A student asks you, “If people have such a similar genetic makeup, then why do you use DNA to understand whether suspects are innocent or guilty of a crime?” Describe how you might answer the students question.
Answer:
While at first, it might look like everyone had similar genetic makeup the human genome is actually incredibly complex we each have an individual set of our own genetic makeup even identical twins have different sets. Another factor is other evidence we have, you can not solely decide if someone is innocent or guilty on a single piece of evidence.

In Mendel's first set of experiments, the two forms of a trait always showed up in the ______ generation
Answer:
Mendel began his studies by growing plants that were true-breeding for a particular trait. ... In his first experiment, Mendel cross-pollinated two true-breeding plants of contrasting traits, such as purple and white flowered plants. The true-breeding parent plants are referred to as the P generation (parental generation).
Explanation:
Hope this helps a little. Pls mark brainliest.
In Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.
What is parental generation?The parental generation is defined as the first set of parents crossed, where the genotypes of the parents will be used as the basis for predicting the genotypes of their offspring (the [tex]F_1[/tex]generation). The P generation is the beginning of Mendel's work on inheritance, or the acquisition of genetic traits by transmission from parents to offspring.
Mendel collected the seeds which is produced by the P plants that resulted from each cross and grew them, while their offspring were called the[tex]F_1,[/tex] or the first filial generation.
Thus, in Mendel's first set of experiments, the two forms of a trait always showed up in the Parental generation or P generation.

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.

❤----------------------------------------------------------------------------------------------------------❤
Carbon dioxide is necessary for photosynthesis in plants. It is so necessary because it combines with water to form glucose or carbohydrates which are incredibly important for plants to provide energy. If they were to not take in carbon dioxide, then they would also not give oxygen which is the most essential for humans.

Answer:
a) Methionine- Serine- Proline- Serine- STOP.
b) UAC- AGA - GGU -
UCG - AUC
c) AUG- UCG- CCA- AGC- UAG
Explanation:
A) The DNA sequence in this question is given as follows: 3 TÁC -AGA - GGT -
TCG - ATC 5'. This sequence undergoes transcription and translation (gene expression) in order to give rise to an amino acid sequence.
The mRNA sequence that will result following transcription is: AUG- UCU- CCA- AGC- UAG
Following translation, each codon in the above mRNA sequence will result in the following amino acid sequence: Methionine- Serine- Proline- Serine- STOP.
B) Anticodons are a group of three nucleotides that are complementary to a codon found on the tRNA molecule. The anticodons for each codon on the mRNA sequence is: UAC- AGA - GGU -
UCG - AUC
C) Silent mutation is a type of substitution mutation in which one or more nucleotide base is replaced by another in such a way that it does not change or alter the amino acid sequence. Using the mRNA sequence: AUG- UCU- CCA- AGC- UAG
A mutated sequence is as follows: AUG- UCG- CCA- AGC- UAG. Note that, G has replaced U in the second nucleotide. However, there is no change in amino acid that results because the same UCU that codes for SERINE is also encoded by UCG.
