Water will boil faster when it is heated from the bottom rather than when it is heated from the top.

The boiling of water occurs due to convection currents. Heavier particles moves from upwards and travels downwards and then they are replaced by lighter particles traveling upwards. This is called convection currents.

As such, water will boil faster when it is heated from the bottom rather than when it is heated from the top.

Answer:

The structure of proteins depends upon the sequence of amino acids joined together.  The sequence of amino acids changes the function of proteins.

Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.

The relationship between a protein's structure and function is direct. The function of a protein is determined by its unique form.

The protein becomes denatured and ceases to function as intended if the three-dimensional structure of the protein is altered as a result of a change in the structure of the amino acids.

Therefore, the order in which amino acids are linked together determines how proteins are structured. The order of amino acids alters how proteins work.

Answer:

are hydrogen, oxygen, nitrogen, and carbon,

Explanation:

which together make up over 99% of the mass of most cells. They are the lightest elements capable of forming one, two, three, and four bonds, respectively

The four most abundant elements in biomolecules are hydrogen, oxygen, nitrogen, and carbon,

The basic building blocks of the living organism are called as biomolecules which are Carbohydrates, Proteins, Fats, Nucleic Acids which make the components of a living cell.

Carbohydrates are polyhydroxy aldehydes or ketones collectively called as saccharides, it can be monosaccharide, oligosaccharide and polysaccharides based on the number of sugars in it.

Proteins are polymers of amino acids where number of amino acids are joined by peptide bond to form polypeptide chain which further converted into protein and it can be classified as primary, secondary, tertiary and quaternary protein.

Nucleic acids are up nitrogenous base, sugar and phosphate; It can be up two types namely, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

The nucleic acid carries the genetic information which is transferred from parent to next generation and proteins which express the genetic character by processes of transcription and translation.

Lipids are organic insoluble fat like substance, soluble in organic solvents like oil,  they include sterols, fat-soluble vitamins, mono-, di- or triglycerides, phospholipids, etc.

Explanation:

Answer:

The correct answer is: Your skin is not as permeable as the lining of your digestive system.

Explanation:

Pool water is mostly composed of water with some chlorine in it. This is why it could never be true that pool water is isotonic with a person's internal fluids, where half of the osmotic pressure is given by sodium. For pool water to be isotonic with our internal body fluids, it should be a 0.9% NaCl solution.

The chloride in the pool water has no special properties that make your body not lose electrolytes.

The reason why swimming in a pool doesn't cause sodium imbalances is because the skin is not as permeable as the lining in our digestive system. We don't absorb water or ions through our skin. The only way we can get more water and electrolytes in our bodies is by ingesting them when drinking water or eating food. Then, our digestive system absorbs it, and after that, the kidneys dispose of the excess water or electrolytes.

The study of population is called demography.

The correct answer is A and C.

A group of the same species living together and interacting with other species is called a population.

The changes in the population are as follows:-

The population can never be constant. The world's population is increasing every day. The birth rate is higher than the death rate.

But in countries, the population is decreasing because there the birth rate is lesser than the death rate due to which the population is decreasing.

Hence, the correct answer is A and C.

Answer:

It would have disastrous consequences on the viability of the individual

Explanation:

The genome can be defined as the genetic material of an organism, which is composed of DNA molecules named chromosomes whose building blocks are four different nucleotides: Adenine, Thymine, Cysotcine and Guanine. The order of these nucleotides specifies the information contained in the chromosomes and, ultimately, in the genome. The genes, which are recognized to be the basic units of inheritance, are genetic sequences composed of ordered nucleotides along the chromosomes. During transcription, a gene encodes different RNA codons (for example, start and stop codons) which are specified by the order of the nucleotide sequence. Finally, the order of the RNA codons will be critical to specify the polypeptide chain during the translation from RNA to protein.

Answer: Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 96.

Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFB genotype is 12.

The population may be evolving because the actual number of individuals with each genotype differs from the expected number of individuals with each genotype.

The population is not at Hardy-Weinberg equilibrium.

Explanation:

The FB allele should accounts for 120 of the alleles (40 × 2 = 80 in FBFB wolves, + 40 × 1 = 40 in FBFW wolves).

the FB allele would make up 20% (120/600) of the total alleles in the population, so the value of p would be 0.2. The allele frequencies of the population must add up to one for it to be valid (what this means is p+q=1); therefore, since the value of p is 0.2, and the value of q is 0.8.

According to the Hardy-Weinberg equation, the expected frequencies of the genotypes would add up to 1.

= p2+2pq+q2

= 1

or

= 0.22+2(0.2)(0.8)+0.82

= 1

or

= 0.04+0.32+0.64

= 1

Answer:

Is this population in Hardy-Weinberg equilibrium?

Answer:

Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Most galaxies have stars distributed throughout them that are born within dust clouds.

Any large, gaseous celestial body that is self-luminous and emits light as a result of its own internal energy sources is a star.

Stars are created when a very huge cloud of gas and dust in space slowly contracts under the force of gravity.

The presence of gas and dust clouds is relatively widespread, and our knowledge of the Milky Way Galaxy's star-forming regions is extensive.

Stars are born within dust clouds and are dispersed throughout the majority of galaxies. Most galaxies have stars distributed throughout them that are born within dust clouds.

The Orion Nebula is a well-known illustration of a dust cloud of this type.

Deep within these clouds, turbulence creates knots with enough mass for the gas and dust to start collapsing under its own gravitational pull.

Thus, this way, the stars are formed.

Explanation:

Living organisms has been classified into prokaryotic or eukaryotic depending on the content of their cell. The basis of classification into prokaryote or eukaryote is the possession or not of a membrane-bound nucleus or organelle.

According to this question where a one-celled organism was seen in a miscrosope, PRESENCE OF MEMBRANE-MEMBRANE-BOUND ORGANELLES is the characteristics that will help in the classification of the organism as a PROKARYOTE OR EUKARYOTE.

Presence of membrane-bound organelles would help classify the organism

as a prokaryote or eukaryote.

Prokaryotes are defined as organism which don't have a true nucleus as a

result of the absence of the nuclear membrane. Eukaryotes on the other
