The theory of evolution states that all the species evolve and change over time, the new species arose from the pre-existing ones and all these species have a common ancestor.

The theory of evolution was put proposed by Charles Darwin. He said that the changes accumulate and are visible into an individual over very long period of times. Darwin's theory was more inclined towards natural selection.

Ancestor is defined as the individual or the species from whom further progenies were formed. Ancestor is the common point for various different species that give us the idea about the evolution must have occurred such that various different species got formed.

Answer:

Cells that lack a nucleus are called prokaryotic cells and we define these cells as cells that do not have membrane-bound organelles. So, basically what we're saying is that eukaryotes have a nucleus and prokaryotes do not.

The new planet has more mass than Earth but the same radius. The mass of the astronaut will be calculated by the use of Newton's gravitational equation. The weight of the astronaut depends completely on its mass and the gravitational acceleration of the planet.

Gravitational acceleration is directly proportional to the mass of the planet and indirectly proportional to the radius of the planet. Hence, when the gravitational acceleration increases the planet's mass will increase therefore the radius will decrease. The astronaut's mass will depend on these factors.

Answer:

The correct answer is - incomplete dominance

Explanation:

An incomplete inheritance or incomplete dominance is an inheritance pattern when the dominant allele of the particular trait is not able to completely mask the effect of the recessive allele and express the mixed or intermediate effect of both the alleles.

Since the gray color is the expression of the mix or intermediate character of both dominant and recessive alleles between black and white, incomplete dominance is the simplest way to explain the inheritance of this character.

Atoms and molecules from the environment are necessary to build new molecules because they provide the necessary building blocks for chemical reactions to occur.

These atoms and molecules are often referred to as reactants, and they undergo a series of reactions to form new molecules, known as products.

When atoms and molecules come together in a chemical reaction, their bonds break and new bonds are formed to create different substances. This process allows for the rearrangement of atoms, leading to the formation of new molecules with unique properties.

The environment is a rich source of atoms and molecules that are essential for life and various chemical processes. For example, the air we breathe contains oxygen molecules, which are crucial for the process of cellular respiration in living organisms. Water, another important molecule found in the environment, provides the necessary hydrogen and oxygen atoms for many biological reactions.

In addition, atoms and molecules from the environment can also serve as nutrients for plants and animals. Through processes such as photosynthesis, plants utilize carbon dioxide from the air to produce glucose, a vital source of energy. Animals, in turn, consume plants or other animals to obtain the necessary molecules for growth, repair, and energy production.

Specific gravity indicates the amount of dissolved substances in the urine.

It is a measure used to assess the concentration of solutes in a solution, in this case, urine. By comparing the specific gravity of urine to that of water, which has a specific gravity of 1, healthcare professionals can determine the relative concentration of dissolved substances in the sample.

This information is helpful for evaluating a person's hydration status and kidney function, as well as diagnosing certain medical conditions. For example, a low specific gravity might indicate excessive water intake, diluted urine, or potential kidney problems, while a high specific gravity could be a sign of dehydration, increased solute concentration, or certain disorders like diabetes insipidus.

Therefore, the correct option is: Cytotoxic T cells release proteins that trigger infected cells to undergo apoptosis and/or cytolysis.An immune response is a reaction that occurs in the human body against foreign substances and infectious agents such as bacteria, viruses, and fungi.

There are two types of immune responses: innate and adaptive. Adaptive immune responses occur when an immune cell recognizes a specific antigen. Adaptive immunity consists of humoral immunity and cell-mediated immunity. The latter is a type of immune response mediated by T cells. T cells come in two major types, namely helper T cells and cytotoxic T cells.Cytotoxic T cells are specialized white blood cells that eliminate infected or cancerous cells in the human body.

Changes in phenotype that are not related to changes in the DNA and that may result from the interaction between the genotype and the environment are known as phenotypic plasticity.

Phenotypic plasticity refers to the ability of an organism to express different phenotypes in response to environmental conditions, without any changes in its DNA sequence.

Phenotypic plasticity is a crucial mechanism that allows organisms to adapt and survive in different environments. It allows individuals with the same genotype to have different phenotypes, enabling them to respond to changes in their surroundings. This flexibility can be observed in various traits such as behavior, morphology, and physiology.

The genotype provides the basic blueprint for an organism's development, but the environment plays a significant role in shaping the final phenotype. Environmental cues can trigger specific gene expression patterns, leading to the development of different phenotypes. For example, temperature can influence the coloration of certain reptiles, with warmer temperatures resulting in darker skin tones.

Phenotypic plasticity is particularly prevalent in organisms with a wide range of habitats. It allows them to exploit various resources and cope with changing conditions. This flexibility can be seen in plants adjusting their growth patterns in response to light intensity or animals changing their reproductive strategies in response to population density.

It is important to note that phenotypic plasticity is not the same as genetic adaptation. Genetic adaptation involves changes in the DNA sequence through natural selection, whereas phenotypic plasticity is a reversible response to the environment.

In conclusion, changes in phenotype that are not related to changes in the DNA can occur due to phenotypic plasticity, which is the result of interactions between the genotype and the environment. This mechanism allows organisms to adjust their phenotypes in response to changing environmental conditions, enhancing their ability to survive and reproduce.
