Darwin called the units of inheritance that pass traits from parents to offspring gemmules.

Charles Darwin proposed the pangenesis theory to describe the units of inheritance between parents and offspring. The minute particles of inheritance that are derived from parent cells were referred to as gemmules. His theory suggested that these gemmules can be modified in any part of the body and are transferred into the reproductive organs of the parents. The gemmules then are transferred to the offspring.

As of now, Charles Darwin's theory is replaced by the chromosomal theory of inheritance, and the concept of gemmules is replaced by that of genes. A theory of inheritance of acquired characteristics (IAC) was further considered by Darwin from which he explained the concept of gemmules.

Answer:

- pollen dispersal: insects and birds are able to spread the pollen of flowers for reproduction

- fruit dispersal: many different mammals (including for example mice, kangaroo, and elephants) eat fruits and then disperse their seeds

Explanation:  

Pollination is the process of transfer of pollen (i.e. male gametes) from plant male reproductive structures (called anthers) to the plant female reproductive organ (stigma). For example, hummingbirds pollinate flowers no other animal can (nectar of these flowers is used as food source). Similarly, honey bees pollinate flowers by transferring pollen from the male anther of a flower to the stigma of another flower. On the other hand, many animals (such as, for example, mice) eat different types of fruits and then disperse their seeds by excreting them. In addition, there are fruits with hooks that attach to the hair of many mammals and thus they can be dispersed to far away places.

It should be noted that birds and insects are pollinators and can spread angiosperm.

It should be noted that pollination simply means the process of transferring pollen from the anthers to the stigma.

The ways of dispersing fruits can be through pollen dispersal such as insects and birds spreading the pollen of flowers for reproduction.

Also, it can be through fruit dispersal as many different mammals like bats, kangaroos, etc.

The false statement about somatic mutation is: (e) they may be inherited in the offspring of mutated individuals.

Somatic mutation is the type of mutation that occurs in the autosomes of an organisms. This does not effect the germ cells of the organisms and hence cannot be passed on from the parent to the offspring. The somatic mutations may cause cancer or other threatening disease.

Inheritance is the transmission of traits or characteristics from the parent to their children. This transmission takes place due to the transfer of the genes that encode these traits. Thus, inheritance is the reason why some traits can be seen in every generation of a family,

Abnormal chemical activity in the body's endocrine system can relate to the release of hormones.

The endocrine system is responsible for producing and releasing hormones into the bloodstream, which act as chemical messengers to regulate various bodily functions. Hormones play a crucial role in maintaining homeostasis, growth and development, metabolism, reproduction, and response to stress, among other functions.

When there is abnormal chemical activity in the endocrine system, it often involves the overproduction or underproduction of hormones, disruption of hormone balance, or impaired receptor sensitivity. These abnormalities can lead to various endocrine disorders.

For instance, conditions like hyperthyroidism result from the excessive secretion of thyroid hormones by the thyroid gland. This leads to symptoms such as increased metabolism, weight loss, rapid heartbeat, and anxiety. On the other hand, hypothyroidism occurs when the thyroid gland produces insufficient thyroid hormones, resulting in fatigue, weight gain, depression, and sluggishness.

Abnormal chemical activity in the endocrine system can also be influenced by factors such as tumors or growths in endocrine glands, genetic predisposition, autoimmune diseases, environmental factors, and certain medications.

In summary, abnormal chemical activity in the body's endocrine system often relates to the release of hormones and can lead to various endocrine disorders characterized by hormone overproduction, underproduction, or imbalances.

Under optimal conditions, one E. coli cell can become two cells approximately every 20 to 30 minutes.

The reproductive cycle of E. coli, a bacterium commonly found in the human intestine, is known for its rapid growth rate under favorable conditions. E. coli cells undergo a process called binary fission, in which a single cell divides into two identical daughter cells.

Under optimal conditions, E. coli can complete the entire process of binary fission in approximately 20 to 30 minutes. This means that the population of E. coli cells doubles every 20 to 30 minutes, leading to exponential growth. The duration of the cell division process can vary depending on the specific strain of E. coli and the environmental conditions in which it is cultivated.

During binary fission, E. coli cells first replicate their genetic material, followed by the division of the cell into two daughter cells. Each daughter cell inherits a copy of the original cell's genetic material, ensuring genetic continuity. The rapid growth rate of E. coli is attributed to its efficient cellular machinery and metabolic processes, allowing it to quickly synthesize the necessary components for cell division.

The statement "hot air with a low relative humidity may actually contain more water vapor than cool air with a high relative humidity" is false because relative humidity is a measure of the amount of water vapor present in the air relative to the maximum amount it can hold at a given temperature.

As the temperature increases, the air's capacity to hold water vapor also increases. Therefore, if hot air has a low relative humidity, it indicates that it contains less water vapor compared to its maximum capacity at that temperature.

In contrast, cool air with a high relative humidity means that it is closer to reaching its maximum capacity for holding water vapor at that lower temperature. Hence, cool air with high relative humidity typically contains more water vapor than hot air with low relative humidity, the statement is false.

The amino acid that would most likely participate in general acid-base catalysis under basic conditions is c. Tyr.

General acid-base catalysis involves the transfer of protons between molecules. Under basic conditions, an amino acid with an acidic side chain would be most likely to participate in this type of catalysis because it can donate a proton to the reaction.

The amino acid Tyr (tyrosine) has a phenolic hydroxyl group on its side chain, which can act as an acid and donate a proton under basic conditions. Therefore, Tyr is the most likely amino acid to participate in general acid-base catalysis under basic conditions.

The other amino acids listed, Gln (glutamine), Leu (leucine), and Ala (alanine), do not have acidic side chains and would not be as likely to participate in general acid-base catalysis under basic conditions.

Photosynthesis is a complex process that can be summarized in two key steps: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).

In the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH. In the light-independent reactions, ATP and NADPH are used to convert carbon dioxide into glucose.

During the light-dependent reactions, light energy is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells. This energy is used to split water molecules, releasing oxygen as a byproduct.

The energy from the absorbed light is then used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH. These energy-rich molecules, ATP and NADPH, are essential for the next step.

In the light-independent reactions, also known as the Calvin cycle, carbon dioxide enters the chloroplasts and combines with a five-carbon compound called RuBP (ribulose-1,5-bisphosphate). This process is facilitated by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).

The resulting unstable six-carbon molecule quickly breaks down into two molecules of a three-carbon compound called PGA (phosphoglycerate). ATP and NADPH from the light-dependent reactions provide the energy and reducing power to convert PGA into PGAL(phosphoglyceraldehyde) through a series of enzymatic steps. Some PGAL molecules are then used to regenerate RuBP, while others combine to form glucose and other organic compounds.

Overall, photosynthesis is a remarkable process where plants capture light energy and convert it into chemical energy in the form of glucose, which serves as a fundamental energy source for both plants and other organisms in the food chain.
