Explain the biological significance of menstruation?
Answer:
Menstruation occurs in cycles. The ovaries prepare an egg (oocyte) for release and the womb (uterus) prepares a lining to nourish the egg if it is fertilised. When the egg is not fertilised, the lining of the womb is shed and a woman gets her period (menstrual bleeding)
Answer:
when the thickened lining of the uterus endometrium leaves the body through the vagina. The lining of the uterus supplies a fertilised egg with nutrients, so if the egg isn't fertilised, then the lining is no longer needed.
3. Will a rubber band or string hold more weight without breaking?
IV:
DV:
Hypothesis:
A rubber band will hold more weight without breaking.
The breaking strength of a material is given by a quantity known as Young’s Modulus. The Young’s modulus(Y) has a different value for different materials and its formula is as follows: Y = F(L)/A(ΔL). Here F is the maximum amount of force that the material can handle without breaking. L is the length of the material, A is the area of cross section of the material, ΔL is the change in length.
As we can see from the above formula, the maximum force handled by a material is directly proportional to the Young’s Modulus of the material. So, a material with a greater value of Y will hold more weight without breaking. As the value of Young’s Modulus is greater for rubber than a string, the rubber band can hold more weight without breaking.
Thus, a rubber band will hold more weight without breaking.

Give one (1) example of an energy transformation.
Answer:
An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical. Because the law of conservation of energy states that energy is always conserved in the universe and simply changes from one form to another, many energy transformations are taking place constantly.

Hi can someone please help me! I am a 7th grader btw
Answer:
Q1)
In the image, the bird is eating a yellow insect and the green insect is camouflaged in the leave, which leaves it unharmed.
Q2)
In several generations, you would expect more green insects. This is due to the survival of the fittest and the useful genes will be reproduced for the next generation. In this case, this is the characteristic of the green colour. However, the yellow insects will be more susceptible to predation so they are less likely to reproduce. This means in several generations, the yellow insects may be extinct and the green insects will be left in abundance.

you are pushing a box to the right with a force of 15n. The friction from the floor opposes the movement with a force of 5n. What is the net force
Answer:
10n
Explanation:
15n-5n=10n
Since the floor opposes the movement you would subtract the amount of friction(5n) from the total force that it was being pushed by (15n), thus you would get 10n.
Which of the following describes a frameshift mutation?
A)Insertion or deletion of a group of nucleotides that is a multiple of three
B)Insertion or deletion of nucleotides that results in a premature stop codon
C)Insertion or deletion of a group of nucleotides that is not a multiple of three
D)Substitution of one nucleotide for another
The correct answer is C because a frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three
Answer:
The statement that best describes the frameshift mutation is insertion or deletion of a group of nucleotides that is not a multiple of three (option C).
Explanation:
Frameshift mutation occurs when nucleotides are inserted or lost in a sequence of bases, altering the reading frame and the way nitrogenous bases are grouped together.
The sequence of nucleotides in DNA determines the mRNA nucleotide sequence, on which amino acid synthesis depends. This sequence is read in threes, and the gain or loss of nucleotides, not multiples of three, causes the normal reading to be altered.
A change in the reading frame can produce an amino acid that does not correspond to the structure of a protein, or the coding of a STOP codon, which interrupts the synthesis of a protein and leaves it incomplete.

Deletion of a DNA base from a gene affects an organism by—
Causing future gametes to have additional chromosomes
Changing the sequence of amino acids in a protein
Causing chromosome fragments to form long chains
Changing the structure of ribose sugar in nucleic acids
Answer:
Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.
Explanation:
A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:
Transcription of the mRNA, which will have the sequence of altered bases. During translation, the mRNA codons will encode at least one different amino acid. The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.In summary, the deletion of a base in the DNA will affect the protein to be synthesized by changing the amino acid sequence of its structure.
The other options are not possible, because the deletion of a base in the DNA of a gene
Does not influence the number of chromosomes that the gametes will have.
It does not produce long chains in the chromosomes.
It does not affect the ribose structure of the nucleic acids.
Deletion of a DNA base from a gene affects an organism by :
B) Changing the sequence of amino acids in a protein.
DNADeletion of a DNA base from a gene affects an organism by the changing the sequence of amino acids in a protein.
A DNA part shapes a quality, with a particular arrangement of nitrogenous bases, which decides the blend of a particular protein. When a erasure of a base happens in such a quality.
Transcription of the mRNA, which is able have the arrangement of changed bases.
The structure of the synthesized protein, which can be changed by changes in its amino corrosive sequence.
Thus, the correct answer is B.

a scientist conducted an expirement to determine the effect of the enviroment on the color of fur of a himalayan rabit
The Himalayan rabbit's environment entirely determines the color of its coat.
How does the environment affect the coat color on the fur of a Himalayan rabbit?The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.

Why is cyanide so lethal
Explanation:
It prevents the cells of the body from using oxygen and when this happens the cells die. It is most harmful for the heart and the brain because they use a lot of oxygen.
Answer:
Cyanide prevents the cells of the body from using oxygen.
Explanation:
When this happens, the cells die. Cyanide is more harmful to the heart and brain than to other organs because the heart and brain use a lot of oxygen. Cyanide poisons the mitochondrial electron transport chain within cells and renders the body unable to derive energy (adenosine triphosphate-ATP) from oxygen. Specifically, it binds to the a3 portion (complex IV) of cytochrome oxidase and prevents cells from using oxygen, causing rapid death

Other than their use in nucleic acid synthesis, which energy source is used uniquely for the synthesis of lipids?
a. atp
b. utp
c. gtp
d. ctp
e. none of these is unique to fatty acid synthesis
The correct answer is option d. CTP stands for Cytidine triphosphate.
In metabolic processes including the formation of glycerophospholipids, where it is used to activate and transfer diacylglycerol and lipid head groups, as well as glycosylate proteins, CTP functions as a coenzyme. Aspartate carbamoyltransferase, an enzyme required for pyrimidine production, is inhibited by CTP.The pyrimidine nucleoside triphosphate known as cytidine 5′-triphosphate (CTP) is similar to the more well-known ATP but uses cytidine as the base instead of adenine. It serves as a substrate in RNA production.A well-known example of feedback inhibition is the allosteric inhibitor cytidine triphosphate (CTP), which prevents an enzyme from initiating a step at the start of a biosynthetic pathway.CTP takes into account both the availability of materials and capacity, providing a more accurate picture of whether demand can be met within a specific time frame than ATP, which solely analyzes material availability and assumes infinite capacity resources.Learn more about Lipids here:
