The first step for this experiment is observation where it is found that a cup of water decreases in temperature. The rest of the steps are described in the explanation part.

A scientific method may be characterized as the process of objectively establishing facts through testing and experimentation. The basic process involves making an observation, forming a hypothesis, making a prediction, conducting an experiment, and finally analyzing the results.

The second step is research in which a cup of water is placed at different temperatures where it can easily change its state from liquid to solid. The hypothesis governs that the amount of water in a cup may lower or decreases when it is exposed to several temperatures.

The experiment is performed on the basis of certain evidence and assumptions in order to predict some conclusion. The control variable is the influence of temperature. The dependent variable is the amount of water and the independent variable is the exposure to temperature.

Therefore, it is concluded that a cup of water decreases in temperature.

An organism can pass a gene mutation to its offspring if the mutation occurs in gamete as a result of sexual reproduction .

A mutation can be transmitted down to an organism's progeny if it happens in a germ-line cell (a cell that will develop into gametes, such as egg or sperm). This implies that the mutation will be present in each and every cell of the growing embryo. A parent's genetic mutation may be carried on to their child through their egg or sperm.

Throughout a human's life, these inherited mutations are prevalent in almost every cell of their body. Cystic fibrosis, haemophilia, and sickle cell disease are examples of hereditary mutations. Large-scale evolution only takes into account mutations that can be passed on to future generations. These are known as germ line mutations and they happen in reproductive cells such as eggs and sperm. Environmental factors contribute to mutations.

Growth in all organisms occurs through the process of mitotic cell division. Cell division is the process of dividing old cells to form new cells, thereby increasing the number of cells needed for growth and various other activities in the body. It is a major and regular process essential to all life.

During mitosis, cells divide to form two identical daughter cells. All cells undergo mitosis and in this way the number of cells in the body increases and the organism grows.

Body tissue grows by increasing the number of cells that make it up. Cells in many tissues of the body divide and grow very rapidly into adulthood. As we grow, many cells mature and specialize in specific tasks in the body.

Answer:

When you think about it - this is a similar case that happens in our species as well. You have groups of people who want to emigrate to different countries in hope for better grassland.  

They emigrate but are immigrants from the perspective of the grassland where they will be.

The other factors that might cause individuals in this antelope herd to emigrate are immigration, increasing birth rate, and decreasing death rate.

When an animal emigrates, it's because its habitat is no longer ideal for it and it needs to move to a new location with a better habitat. Animals that migrate or emigrate never go back to the place they were originally from.

This is a similar situation to one that occurs in our species. There are various groups of people who want to immigrate to various nations in search of better grasslands. From the perspective of the grassland where they will be, they migrate but are immigrants.

Therefore, Immigration, a rising birth rate, and a declining death rate are some additional factors that could result in members of this antelope herd leaving the group.

The products of the light-dependent reactions are= ATP, NADPH, and O2, and the products of light-independent reactions are= Sugars, ADP, and NADP+.

Photosynthesis has two parts: one is light-dependent and another one is a light-independent reaction (also known as-Calvin cycle). The process is vice versa, where few inputs of the light-dependent reaction are used to make the outputs for the light-independent reaction, and few inputs of the light-independent reaction are used to make the outputs for the light-dependent reaction.

The goal of a light-dependent reaction is to convert light energy into chemical energy. And the location of light-independent reaction is at Chloroplasts—stroma.

Answer: Two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

Explanation:

The genome of an organism is found in a molecule called DNA (deoxyribonucleic acid). The main function of this DNA molecule is the long-term storage of information to build other components of cells, such as proteins and RNA molecules (ribonucleic acid); and the portion of the genome that codes for a protein or RNA is known as a gene. These protein-coding genes are composed of trinucleotide units called codons, each of which codes for an amino acid. For a protein whose sequence is encoded in the nucleotides of DNA to be synthesized, that DNA molecule must first be transcribed into a molecule called messenger RNA, and this molecule is used for a process called translation or protein synthesis. The sequence of the genetic material is composed of four distinct nitrogenous bases, which are represented by letters in the genetic code:

The genetic code is the set of rules that defines how a sequence of nucleotides in RNA is translated into a sequence of amino acids in a protein. This code is common to all living things, which shows that it has had a unique origin and is universal. So, the code defines the relationship between each sequence of three nucleotides (codon) and each amino acid.  The number of possible codons is 64, of which 61 code for amino acids (one of them being the start codon, AUG) and the remaining three are stop sites (UAA, UAG, UGA). The codon sequence determines the amino acid sequence in a particular protein, which will have a specific structure and function.

However, the genetic code has redundancy but no ambiguity. For example, two different codon can code for the same amino acid, and the differences between codons encoding the same amino acid have differences in the third position. This is explained by the wobble effect, where the same anticodon (present in the transfer RNA that loads with the amino acid and interacts with the codon in the messenger RNA) can establish interaction with different codons, which differ in their third base. This is why, in general, tolerance to change at this position is greater than at the first and second positions, and therefore tends to be less represented in the case of variations that result in pathologies.

Thus, two people can have different DNA sequences but these sequences can code for the same amino acids due to the redundancy of the genetic code in which two different codons can code for the same amino acid.

When you look at a green object, the object reflects green light and absorbs other colors of the visible spectrum. The green light is then transmitted to your eye, where it is focused by the lens onto the retina.

The retina contains specialized cells called rods and cones that are sensitive to different wavelengths of light. The cones in the retina are responsible for color vision and are most sensitive to different colors in the visible spectrum, and when the green light reaches the cones, it triggers a neural signal that is sent to the brain, where it is interpreted as the color green. The absorbed light colors are not reflected and are green absorbed by the object, they are not transmitted to green the eye, so they are not perceived by the observer.

Wise dominion over the process of photosynthesis can be exercised in such a way that all the people and animals can benefit from it and we can use it correctly.

Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are formed by the reaction of carbon dioxide and water.

Photosynthesis is performed by the majority of plants, algae, and cyanobacteria; these organisms are known as photoautotrophs. Photosynthesis is responsible for producing and maintaining the oxygen content of the Earth's atmosphere, as well as supplying the majority of the energy required for life on Earth.

Stochastic sampling error (i.e., genetic drift) causes populations to lose genetic diversity due to chance.

Genetic drift is a result of sampling error because individuals are randomly chosen when a population is sampled. A random selection is one in which each member of the population has an equal chance of being chosen.

The random change in allele frequencies caused by stochastic sampling of alleles from the previous generation is known as genetic drift (independent of demographic stochasticity).

The variety of various inherited features within a species is referred to as genetic diversity. There would be many people with a wide range of diverse traits in a species with significant genetic diversity. For a population to adapt to changing surroundings, genetic variety is essential.

The best example of a Mendelian trait in humans is phenylketonuria. This illness is an illustration of a Mendelian trait since it is passed down from parents to children when both parents have heterozygous (Aa) and homozygous (Aa) circumstances.

Mendelian qualities are determined by all of Mendel's postulated Laws of Inheritance and are traits that are transferred from parents to children through dominant and recessive alleles of a gene. The lack of an enzyme that turns the amino acid phenylalanine into tyrosine is the root cause of the autosomal recessive inherited disorder. As a result, the amino acid builds up and is converted into the toxic form of phenyl pyruvic acid, which builds up in the brain of the person and causes r-e-t-a-r-d-a-t-i-o-n.
