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.
If solution A has more solute particles dissolved in it than solution B, then solution A is _____.
Answer:
Hypertonic
Explanation:
big brained
If solution A has more solute particles dissolved in it than solution B, then solution A is hypertonic.
What is a hypertonic solution?Tonicity exists as a measure of the sufficient osmotic pressure gradient. Tonicity depends on the comparative concentration of selective membrane impermeable solutes across a cell membrane which specify the direction and extent of osmotic flux. A hypertonic solution contains a higher solute concentration than another solution. In our cells, when the concentration of ions outside the cell exists greater than inside, it's hypertonic. Tonicity in living systems If a cell stands positioned in a hypertonic solution, water will leave the cell, and the cell will shrink.
An example of a hypertonic solution lives in the interior of a red blood cell corresponding with the solute concentration of fresh water.
The correct answer exists in a hypertonic solution.

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%.

how do cells use oxygen during cellular respiration
Answer:
In cellular respiration, cells use oxygen to break the sugar molecule. That releases the energy which is then transferred to an ATP (adenosine triphosphate) molecule. ATP is the fuel that cells need for energy. And where does cellular respiration happen?
Explanation:
A species of frog lives in a forest. A snake species moves to the ecosystem where the frogs live and begins to hunt the frogs. Using your
understanding of natural selection, what is the most likely explanation of what will happen to the frog population when the snakes, who
are predators and will hunt the frogs, move into the ecosystem?
O A. Some of the frogs would try to develop new traits to avoid the predator and pass those on traits to offspring, and the other frogs
would die.
OB. All of the frogs would try to develop new traits to be able to avoid the predator, and they will all survive and pass on their new
traits to offspring.
OC. The frogs that were born with traits that allow them to avoid the snake would be more likely to survive and reproduce, and the
frogs that are not would be less likely to survive and reproduce.
o D. Since all of the frogs have identical traits, they would all be equally good or bad at avoiding the snake and so they would all survive
and reproduce or they all would die.
Answer:
The answer is C
Explanation:
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.
When the snakes moved in, the environment changed. The frogs that have the traits to avoid the snakes will be able to adapt to this change and survive and reproduce. Those without these traits will be found by and eaten by the snakes.

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.

Is it possible to know the location of a gene on a chromosome if only one other gene is used?
Answer:
The arm of the chromosome. Each chromosome is divided into two sections (arms) based on the location of a narrowing (constriction) called the centromere. By convention, the shorter arm is called p, and the longer arm is called q. The chromosome arm is the second part of the gene's address.

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.

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.
