Answer is CUCAAUGAU
Choose an organism and predict a trait that would be helpful for its survival. Do you think this could be an evolutionary change? What would have to happen for this trait to be expressed?
In a DNA strand, you find that 20% of the bases are Adenine. What percentage of the DNA would be Cytosine?
Answer:
Yes
Explanation:Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%.

By using mutable collagenous tissue, what advantage do Echinoderms have?
Answer:
The properties of this connective tissue are mutable for a short period of time, under neural control, which provides certain mechanical advantages, which include the ability to maintain various postures without muscular effort; that is, it allows Echinoderms to change the consistency of the body, this is useful to escape predators or crawl along the seabed.
Explanation:
Echinoderms comprise the marine organisms known as starfish, sea urchins, sea cucumbers and sea lilies. These present, for the most part, benthic habits and are distributed from intertidal environments to deep bottoms and at different latitudes. They have a mutable collagenous tissue that allows them to change the consistency of the body, that is, they can rapidly change their stiffness and is involved in processes such as fission and autotomy. Some echinoderms quickly switch back and forth between being soft and stiff, which helps crawl along the seabed. Others twist only once from stiff to soft, letting a starfish cut off one of their arms to escape a predator, that is, they can drop an arm when attacked by a predator. When this happens it is called autotomy or autoamputation and the nervous system tells the mutable collagen tissue near the base of the arm to disintegrate. The wound heals and then the arm grows back, a process that can take weeks to months, depending on the species.
Answer:
saves energy
Explanation:
Mutable collagenous tissue is used to lock an Echinoderm into position.

Briefly describe the layers of the atmosphere:Troposphere-Exosphere-Stratosphere-Mesosphere-Thermosphere-
Answer:
Explanation:
-Troposphere. It is the lowest layer and encompasses the Earth's surface up to an average height of 12 kilometers; about 17 kilometers in the equatorial regions and about 9 kilometers at poles
- Stratosphere.Separated from the troposphere by the tropopause is this layer containing 19 percent of the atmospheric gases, but very little amount of water vapour.
-Mesosphere. It is located above the stratosphere up to a height of 80-85 kilometers in the mid-latitudes, where the mesopause is located.
-Thermosphere. From the upper limit of the mesopause extends the thermosphere, known as the upper atmosphere.
-Exosfera. It is the last layer, the outerest until connected with the solar wind.

O variables
O control groups

O correlation
Answer:
correlation
Explanation:
By examining correlation, scientists can test predictions for situations in which it is impossible or unethical to use experiments.
Correlation determines if there is, and measures the strength of the relationship between two variables. Hypotheses are usually tested by experiments in science, but some situations make experiments impossible or unethical to be performed directly. In such cases, simulational experiments are performed and correlation is used to theoretically determine or predict the outcome of situations.

Find out two types of water purification and name and describe them here.
Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.
i need some help asap
Answer:
B) Nucleotides that stores the code for proteins
Explanation:
RNA and DNA are polymers made of long chains of nucleotides
The copper wire is cut into three pieces of unequal lengths. All three pieces of copper would have (1 point)
A the same mass
B the seſme physical properties
C different crystal structures
D different arrangement of atoms
B.) The same physical properties.
Also the copper wire would also have the same Chemical Properties. They wouldn't have a different arrangements of atoms because that would mean they are a different substance. They wouldn't have the same mass whereas they are now in 2 pieces. Copper is not a crystal meaning it would not have any crystal structures. That leaves the only applicable answer to be B. Also in case you need to find whether or not two identical substances are the same would be by testing the melting point, hardness and solubility. I just finished working on this section in my own 8th grade Science class so I think this should either help you now or later on.
Hope this helps.

The measurement used for insulation is called the: H-factor R-factor X-factor L-factor
Answer:
R-factor.
Explanation:
Insulation can be defined as the process in which physical objects (materials) oppose the flow of current by providing a least resistance path or the opposition to the conduction of heat energy.
R-factor is an abbreviation for thermal resistance. The R-factor is the most commonly used measurement for providing all of the informations about the insulating properties of an insulator. Therefore, the measurement used for insulation is called the R-factor.
Most manufacturers specify the R-factor on the label of an insulating material.
Generally, the higher the R-factor of an insulating material the better it is for insulation.
Hence, the ability of a material to prevent the flow of heat or electricity (current) is largely dependent on its R-factor.
How do producers get the nitrogen they need to live and grown

Which sequence best explains the relationship between DNA and protein structure and function?
Answer:
DNA base triplets → amino acid sequence → protein folding pattern → protein shape and function
DNA sequence provides the code for the amino acid sequence. The amino acid sequence determines the protein structure, which affects the protein's function.
What is the relation between DNA and protein?The relation between DNA and protein can be described as follows:
DNA carries the genetic code: DNA is made up of a long chain of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine, guanine, cytosine, and thymine. The sequence of these bases carries the genetic code that provides the instructions for the synthesis of proteins.
DNA is transcribed into RNA: The DNA code is transcribed into a complementary RNA (ribonucleic acid) molecule through a process called transcription. RNA is similar to DNA, but it is made up of a different sugar (ribose) and a different nitrogenous base (uracil).
RNA is translated into protein: The RNA molecule is then translated into the amino acid sequence of a protein through a process called translation. This involves the use of transfer RNA (tRNA) molecules, which carry specific amino acids and bind to the RNA molecule at specific codons (sequences of three nucleotides). The sequence of codons in the RNA molecule determines the sequence of amino acids in the protein.
Protein structure determines function: The amino acid sequence of a protein determines its three-dimensional structure, which in turn determines its function. Proteins can have a variety of functions in the body, including catalyzing chemical reactions, transporting molecules, providing structural support, and regulating cell function.

the cover of a book has an area of 400 cm², the book has a
heigh of 4 cm. what
is the books volume? use the
correct unit for volume in your awnser.
Answer:
1600cm³
Explanation:
The volume of a cuboid can be calculated as follows;
V = L × B × H
Where;
L = length (cm)
B = breadth or width (cm)
H = height (cm)
However, in this question, the area of the book is said to be 400cm². Since area of a rectangle or rectangular-shaped object like the book is L × B, this means that the length and breadth has been combined in the area. Hence;
Volume of the book = area of the book (L × B) × Height of the book (H)
Volume = 400cm² × 4cm
Volume = 1600cm³
Therefore, the volume of the book is 1600cm³.
