The statement that best explains the pattern of inheritance described above is that if the two alleles of an inherited pair differ, then one determines the organism's appearance and is the dominant allele (option C).

Allele is the alternative form of the same gene occupying a given position, or locus, on a chromosome.

According to Gregor Mendel in his law of inheritance, he deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Dominant alleles are alleles that are physically expressed while the recessive alleles are those that are masked by the dominant alleles.

According to this question, Mendel discovered that one parent's trait disappeared in the F1 generation of his experiment, only to reappear in one quarter (¼) of the F2 generation.

This is as a result of the concept of dominance or recessiveness in the allele encoding the particular trait. The dominant allele expressed itself over the recessive one in the F1 generation.

Answer:

The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.

Explanation:

The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.

Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.

The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).

Thus, these are the differences between the three classes of platyhelminthes.

Approximately 10 percent of the energy is passed on to the consumer and approximately 90 percent of the energy is lost as heat.

This refers to an interconnecting diagram that shows the overall food relationships between organisms in a particular environment.

90 percent of energy is usually lost as heat thereby allowing for the transfer of only 10 percent of energy to the consumers.

Air pollution affects everyone equally is true statement.

When pollutants are released into the atmosphere, they endanger both human health and the health of the entire planet. The World Health Organization (WHO) estimates that air pollution causes close to seven million deaths worldwide each year.

Currently, nine out of ten people breathe air that contains more contaminants than the WHO's recommended levels, with those in low- and middle-income nations suffering the most.

The 1970-established Clean Air Act gives the U.S. Environmental Protection Agency (EPA) the power to protect public health by controlling the emissions of certain dangerous air pollutants.

Therefore, Air pollution affects everyone equally is true statement.

Classification of organisms is done while considering many factors such as:

Cell type- whether the organism is prokaryotic or eukaryotic

Cell structure- This includes both the presence and composition of the cell wall

Body type- whether the organism is multicellular or unicellular

Mode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)

The only word among the available words that do not fit the pattern would be temperature.

Ash, dissolved gases, and silica content are similar in the way that all of them are made up of matter.

Matter refers to any substance with weight and is able to occupy space. Ash is made from solid particles. dissolved gases are gases, and silica contents are also from solids.

Temperature, on the other hand, is a scalar quantity. It is not something that can be held or seen. It has no weight and neither does it occupy space.

The information provided is NOT sufficient to indicate if the TACGTGGACTGAGGACTCCTC sequence is a 'sense' strand or 'antisense' strand.

DNA is a double helix molecule composed of two long chains of nucleotides linked by hydrogen bonds.

During transcription, the sense DNA strand is actively used as template to produce a complementary RNA molecule.

In consequence, it is required to know the sequence of the resulting RNA to determine if the sequence above belongs to a 'sense' strand or 'antisense' strand.
