As we know that the leaves of plants are waterproof due to cuticle. On the same way, take
some pieces of paper of leaf size and make them waterproof. After completion, put half of these
paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof?
Explain your observations and results with justifications
Answer:
No.
Explanation:
No, all the pieces of paper did not remains waterproof because expansion of paper occur due to high temperature of hot water. We know that materials expand when they experience high temperature and contract when they observe cold temperature. So the pieces of paper remains waterproof which were put in cold water while those were not waterproof if they are put in hot water.

conduction of water by root pressure and suction pressure
Answer:
Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground.

Explanation:
If capital D = the allele for dimples, and lowercase d = the allele for NO dimples, what percentage of the offspring will show having dimples, with parents having genotype Dd (capital D and lowercase d) and genotype dd (two lowercase ds)?
If D is the allele for dimples and d is the allele for no dimples, a percentage of offspring with genotypes Dd is 50% and 50% dd will be produced with no dimples.
How will the allele for dimple express?The dimple appears when the D is present, which occurs in both the purebred dominant case (DD) and the heterozygous case (Dd), so when the dd is present, no dimple is seen. The dimple is dominant over the no dimple, so when the heterozygote Dd crosses with the purebred dd then 50% will have dimples and the other 50% won't, as the heterozygotes will produce both D and d types of alleles that will combine with d to make two types of offspring.
Hence, if D is the allele for dimples and d is the allele for no dimples, a 50% percentage of offspring with genotypes Dd and 50% of offsprings with genotype dd will have no dimples.

Explain the difference between a diploid and a haploid cell.
can sum1 tell me the difference plzzzz
Difference Between Haploid And Diploid
Haploid cells contain only one set of Chromosomes (n).
Diploid, as the name indicates, contains 2 sets of chromosomes (2n).
A-Haploid cells are formed by the process of meiosis.
Diploid cells undergo mitosis.
B-In the higher organism, such as humans, haploid cells are only used for sex cells.
In the higher organism, such as humans, all other cells beside sex cells are diploid.
C-Examples of haploid cells are gametes (male or female germ cells).
Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells

Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide exchange in the DNA. When they compared gene sequences, they saw same number of nucleotide bases. Which type of mutation had most likely occurred? deletion insertion inversion substitution
Answer:
substitution
Explanation:
A substitution is a point mutation where a nucleotide base (either adenine, guanine, thymine or cytosine) is replaced by a different base pair. In contrast to insertions or deletions, substitutions don't change the number of bases in the DNA sequence. Moreover, inversions are large genetic rearrangements where the genetic sequence is reversed. A substitution may have different effects: change a codon to another (changing the protein sequence when codons are translated into amino acids), produce a stop codon, cause synonymous mutations (i.e., neutral mutations that don't alter the amino acid sequence due to the degeneracy of the genetic code), etc.
A ___ mutation occurs when a base in the DNA sequence is replaced by a different base.
Answers:
substitution
aggression
deletion
insertion

Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence
Answer:
It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

how does the structure of DNA determine the structure of RNA?
A- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases cytosine in DNA and uracil in RNA will pair together when DNA acts as a template for constructing RNA.
B- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases uracil in DNA and guanine in RNA will pair together when DNA acts as a template for constructing RNA.
C- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases adenine in DNA and thymine in RNA will pair together when DNA acts as a template for constructing RNA
D- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA
The nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).
During transcription, a sequence of DNA is used as template to create an RNA, usually an mRNA.In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Guanine, Thymine, Cytosine and Adenine.According to the base pair rules, Adenine pairs with Thymine (Uracil in RNA), whereas Guanine pairs with Cytosine.In conclusion, the nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).

What are the challenges of traveling to and living on Mars?
Answer:
Here I hope this can help you with your question! :)
Explanation:
You might be travelling with other astronauts in a journey that will take between seven and 12 months, packed in a tight space. So you’ll need to stretch and probably find a way to have part of the spacecraft spinning to create artificial gravity. Having no gravity for a long time can cause a lot of painful health problems for astronauts. Then there’s the powerful cosmic radiation that comes mostly from our Sun. It can damage electronic equipment on board and create health problems for the crew. You and the crew will have to solve these problems on your own. The atmosphere is not breathable: it is only 1% the thickness of our atmosphere, mostly made of carbon dioxide, argon, and nitrogen with only a small amount of oxygen. Growing plants on Mars is not going to be easy. The soil is really salty and acidic. It is still unclear if we should bring bacteria to Mars to help plants grow (as they do on Earth). Finally, I would say any mistake in flight or during the exploration can hurt or kill you. The room for error is really narrow. Why on Earth would you engage in such a dangerous, life-threatening endeavour? I guess the answer lies in what has made humans explore throughout the centuries. We are always looking for the next frontier.
Answer:
- Travelling from Earth to mass requires a greater magnitude of escape velocity in order to overcome the Earth's gravitational attraction.
- Travelling to Mars is a great distance which is approximately the twice of Earth's distance from the sun (approximately 3.0×10^11 m), hence the Traveller has a possibility of not reaching the destination.
- Travelling to Mars requires a skilled Traveller and experienced, yet those travellers are scarce allover the World.
- It is also very expensive.
- Mars has a different and a greater gravitational attraction than that of the earth, hence a person of earth may not cope with it.
-Mars is very hot than Earth, hence the living on it is affected by the climatic diversion
