O.It will rain tomorrow.
D. It is raining.

Growing crops that need less water is an action that is a sustainable agricultural practice. Thus, the correct option is A.

Sustainable agriculture practice may be defined as those actions which are environmentally favorable, profitable, and significant for communities. It includes the needs of society without compromising the ability for current or future generations.

Importing water from another region provokes maintenance and labor cost. Feeding a large population with factory farming affects the productivity of the crops. Irrigating fields with groundwater utilize more and more water consumption.

Therefore, the correct option for this question is A.

Answer:

There are numerous forms of pollution and environmental problems that human beings have been causing since the beginning of the industrial revolution and, in particular, since the second half of the last century. Pollution without borders associated with all human activities and which, along with other serious problems, is degrading all ecosystems and contributing to climate change whose consequences we are already experiencing. The costs of this environmental degradation have not been taken into consideration until recently, but it is beginning to be understood that they must be incorporated in the evaluation of any project; They cannot be “outsourced”, as has been done, because it is absolutely unsustainable.

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.

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.

d. Presence of membrane-bound organelles

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

hand have a true nucleus as a result of the presence of the nuclear

membrane.

When viewing a one-celled organism with a microscope, we are able to

classify the organism based on the presence or absence of a membrane-

bound organelle.

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.

Random sampling and mark and recapture methods are both commonly used to estimate population sizes, but they have different strengths and weaknesses.

Random sampling involves selecting a random sample of individuals from a population and using that sample to make inferences about the population as a whole. This method is typically used when the population is large and diverse, and it is difficult to observe or count all individuals. Random sampling is also useful when the population is not easily marked or tagged, as it does not rely on the use of markers.

On the other hand, mark and recapture methods involve marking a subset of individuals in a population, then releasing them back into the population and later re-capturing them. The number of marked individuals that are recaptured is used to estimate the population size. This method is typically used when the population is small, and it is relatively easy to observe or count all individuals. Mark and recapture methods are also useful when the population is easily marked or tagged, such as with fish or birds.

A situation in which random sampling would work best is a study of the population of deer in a large forest. The forest is too vast to observe or count all individuals, so a random sample of deer would be selected and observed to estimate the population size.

On the other hand, a situation in which mark and recapture methods would work best is a study of the population of fish in a small lake.

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

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.

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.
