What characteristic do all protozoa display?
autotrophic
immobile
vertebrate
eukaryotic
The characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.
What do you mean by Protozoans?Protozoans may be defined as single-celled microscopic organisms that significantly belong to the kingdom of Protista. These organisms are eukaryotic in nature, and hence they have a true and membrane-bound nucleus in order to function properly.
Some protozoans are definitely attached to the substrate or construct cysts. So, they do not migrate around. But some protozoans have the capability to move around at some stages in their life cycles mostly after the cell division.
So, option B is eliminated. Protozoans are heterotrophic as well. They use organic carbon as a source of energy. So, option A is eliminated.
Therefore, the characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.

Which statement is true of carriers? Select all that apply.
A) They have one dominant allele.
B) They express the recessive trait.
C) They are heterozygous for a recessive disorder.
D) They can pass a gene for a recessive disorder.
B. They express the recessive trait
The carriers for a disease in a pedigree analysis is a heterozygous. They contain a dominant and a recessive allele. Thus, correct options are A, C and D.
What are genes?A gene is a segment of DNA that contains all the information for the development of organism. A carrier in genetics, is an individual who “carries” and can pass on to its offspring an allele associated with a disease and does not show symptoms of that disease. A carrier is an organism that carries two different alleles of a recessive gene and is thus heterozygous for that the recessive gene.
Dominant genetic disorders are those in which a mutation in just one copy of the gene pair is required for the disorder to develop. However, in recessive genetic disorders both alleles need to be recessive for the gene. This disease symptoms are only observed in case of homozygous condition.
Therefore, the correct options are A, C and D.

How does thermal energy impact the lower layers of atmosphere?
Answer:
Explanation:
Land and water absorb most of the solar radiation from the sun. Some of this solar energy from land and water is then transferred to the lower atmosphere which is in contact with the continents and oceans. From Land, this occurs mostly as heat energy or infrared radiation. Water usually transfers this energy through the evaporation of water into the atmosphere

Answer:
Houses nasal conchae to enhance turbulence for filtering air. larynx. Prevents food and liquid from entering the rest of the respiratory tract.
Explanation:
Houses nasal conchae to enhance turbulence for filtering air through nasal cavity. Hence, the correct option is A.
What is nasal cavity?It is a large air filled space within the nose and is part of the respiratory system. It is lined by an inner thin layer of moist mucous membrane which helps to humidify and filter the air as it is breathed in.
The nasal cavity is divided into two parts-the right and left nasal cavities, separated by a thin bony wall called septum. It is involved in the sense of smell, as small receptors located in the mucous membrane of the nasal cavity are responsible for detecting different odors.
Overall, the nasal cavity is a crucial part of the respiratory system and plays an important role in protecting the body from inhaled irritants, facilitating the sense of smell. Hence, the correct option is A.

12. What is another name for the Calvin Cycle and why?
Explanation:

This process is called carbon fixation, because CO2 is “fixed” from its inorganic form into organic molecules. ATP and NADPH, which were made during the light dependent reactions, use their stored energy to convert carbon dioxide into a three-carbon compound called G3P.

What is DNA?Deoxyribonucleic acid (DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macro molecules that are essential for all known forms of life.

2. Write a micro-theme(short paragraph 100-300 words) using and explaining the following terms.
a. "Survival of the fittest"
b. Adaptation
c. Evolution
Answer:
The process through which creatures evolve is known as evolution. Mutations cause genetic variety throughout populations, and the ecosystem works with this diversity to select people who are most suited to their surroundings. Eventually, a species can develop into a plethora of others; as a theory suggests that sapiens started as monkeys but evolved into the humanoid beings that we are today. In biology, adaptation is the procedure where a species fits to its habitat; it is the outcome of natural selection acting on hereditary diversity over numerous generations. Survival the fittest is a saying that suggests the fittest survive, not the weak. This is commonly seen in everyday life, whether with humans, animals, plants, it holds the same meaning. An example would be that a person in better physical and mental health would go farther and live longer than one with weak physical and mental health.
The concept of "survival of the fittest" is a key tenet of evolution, which refers to the idea that individuals with traits that provide them with a competitive advantage in their environment are more likely to survive and reproduce than those without these traits. This process of natural selection leads to the gradual accumulation of beneficial traits in a population, resulting in adaptation and evolution over time.
What is adaptation?Adaptation refers to the process by which organisms develop characteristics that allow them to better survive and reproduce in their environment, such as camouflage or the ability to digest new types of food.
Evolution refers to the broader process of change over time in a population's genetic makeup and physical characteristics, resulting from the interaction between genetic variation, natural selection, and other factors. Together, these concepts help explain how organisms are able to adapt and change over time, resulting in the diversity of life that we see today.
The study of evolution has important implications for understanding the history and development of life on Earth, as well as for addressing modern challenges such as biodiversity loss and climate change.
