Prokaryotic cell and eukaryotic cell are the two different types of cells. Eukaryotic cells are the true-cells which have some organelles which are absent in prokaryotic cells. Prokaryotic cells are the primitive cells. Thus, correct option is B.

Prokaryotic cell is the primitive cell. It is present in bacteria and archaea. The genetic material is not stored within a membrane-bound nucleus, it is stored in a nucleoid that floats in the cytoplasm.

Eukaryotic cell is the true cell. It is present in all the higher organisms. Eukaryotic cell is a cell which possesses a clearly visible well-defined nucleus.

The main difference between the prokaryotes and eukaryotes is that the prokaryotic cells does not have any membrane-bound organelle. Also, the nucleus does not have membrane, it is free in the cytoplasm.

Therefore, the correct option is B. The cytoplasm is the only feature which is same in both prokaryotic and eukaryotic cell.

Troposphere is the lowest most layer of Earth's atmosphere. The mean height of troposphere from the surface are 18 km in tropical regions, 17 km in middle latitudes, and 6 km in polar regions.  

There exists an inversion layer called as tropopause, which acts as border between troposphere and stratosphere. The air temperature keeps on decreasing as we go high in the tropopause but remains constant throughout its thickness.

Usually, scientists use weather balloon as an instrument to take measurements in the upper troposphere.

Weather balloon also known as sounding balloon is a balloon that carries the measuring device (known as radiosonde)  with it to the intended heights and stays there for long duration.  The device then obtains all the measurements such as atmospheric pressure, temperature, wind speed, humidity etc and send them back to the scientists.

In addition, scientists may compare these data with those obtained from other means such as aircraft data and satellite data.

Plasma is a high-energy state of matter with ionized particles, unlike solids, liquids, and gases. Physical changes do not alter chemical composition, whereas chemical changes result in new substances.

The state of plasma differs from the other common states of matter (solid, liquid, and gas) in that plasma has variable volume and shape and consists of ionized particles with significant energy. This energy allows the electrons to escape from their atomic orbitals and move freely, which is not the case in other states.

As to the difference between physical and chemical changes, a physical change involves a change in the state or appearance of matter without altering the chemical composition, while a chemical change involves the breaking and forming of chemical bonds, resulting in new substances with different properties.

For example, melting ice is a physical change as water transitions from solid to liquid state, while burning wood is a chemical change since it converts the wood into ash and carbon dioxide.

Final answer:

A woman with type A blood and an OO genotype man can have children with either type A or type O blood. Both parents are heterozygous for the MN blood group, resulting in three possible genotypes for their children: MM, MN, or NN. This represents codominance and multiple alleles in inheritance.

Explanation:

The question involves understanding how ABO blood types and MN blood groups are inherited, which is a classic example of codominance and multiple allele inheritance patterns. Since the woman has type A blood and her father was type O, her genotype must be AO. The man has blood type O, so his genotype is OO. When predicting the ABO blood type of their children, only type A or type O is possible. As for the MN blood group system, both parents are heterozygous, meaning that their genotypes are MN. The possible combinations for the offspring would result in 25% MM, 50% MN, and 25% NN. Codominance is observed here because both M and N antigens are equally expressed when inherited together.

Technological advancements in sewage treatment have revolutionized waste management, with separate sewer systems, constructed wetlands for water reclamation, and advanced purification processes leading to significant environmental and public health benefits.

Explanation:

Technology has been essential in addressing sewage issues, particularly the integration of aging infrastructure with modern environmental needs. Advances in wastewater management include separate sewer systems which prevent system overflow by directing only wastewater to treatment plants. Stormwater, on the other hand, is directed to rivers or is temporarily stored in underutilized spaces such as caverns or quarries. One significant technological method for treating sewage includes engineered wetlands, which leverage natural processes for purifying water. These constructed wetlands support plant growth that assimilates nutrients, providing a form of tertiary treatment. The recovered water can then be subjected to advanced processes like membrane filtration or ultraviolet irradiation for further purification, ultimately producing water clean enough to be reintroduced into municipal water systems or used for irrigation.

The concept of water reclamation from wastewater highlights the integration of environmental sustainability practices into technological development. This approach underscores current trends in both industrialized and developing countries to constructively reuse waste and make efficient use of scarce water resources.

Recalling the historical context, such as London's Great Stink and the implementation of the Clean Water Act of 1972, illustrates the long-standing link between technological advancements in sewage treatment and major improvements in public health and environmental quality.

Isovolumetric relaxation and ventricular filling, part of the ventricular diastole phase of the cardiac cycle, are crucial processes in the heart's function of pumping blood throughout the body.

The phases of isovolumetric relaxation and ventricular filling take place during the ventricular diastole phase of the cardiac cycle. During isovolumetric relaxation, the ventricles are resting and the ventricular pressure is falling. Consequently, the blood will start filling the ventricles, which is the ventricular filling phase. Changing pressures and valve positions control these transitions between phases throughout the cycle.

Answer:

Sweating and panting are examples of homeostasis.

Explanation:

Homeostasis may be defined as the state of an organism's body to maintain the constant internal environment. Warm blooded animals need to maintain their internal temperature.

Sweating occurs during excessive heat. The body maintains homeostasis by sweating as sweating provides cooling  and bring down body temperature to the normal temperature. Panting is another way of maintaining homeostasis. Individuals take short and quick breaths in case of excessive heat.

Thus, panting and sweating are the characterstics of homeostasis of life.

The seed coat's most significant role is to safeguard the seed embryo. It protects the embryo from environmental stressors and controls water intake, thus signaling the start of germination.

The most important function of the seed coat is to provide protection for the embryo within the seed. The seed coat acts as a physical barrier against various environmental stresses such, dehydration, and harmful pests which may damage the embryo. It also controls water intake by the seed; this is crucial as the uptake of water signals the start of the germination process. The hard layer of the seed coat often prevents water from entering the seed until conditions are suitable for germination.
