An elephant is an herbivore which means that it gets its source of nitrogen to form the DNA or proteins from the plants it eats.

An herbivore is a heterotrophic animal that sustains by eating living plants that contain all required nutrients to synthesize the biomolecules of the organism such as for example proteins, DNA and lipids (i.e., fats).

Therefore, with this data, we can see that herbivores are heterotrophic animals that obtain all nutrients to sustain their metabolic activities by eating plants, which is the case for the elephants.

Answer:

C. Compound Light Microscope

Explanation:

Commercial harvesting and use of gonads and legs is not typically associated with amphibian decline. The correct option is C.

a. An amphibian fungus, Batrachochytrium dendrobatidis: This fungus, commonly known as Bd, is one of the major causes of amphibian declines worldwide. It infects the skin of amphibians, disrupting their ability to breathe and absorb water. Bd has been responsible for population declines and extinctions in numerous amphibian species.

b. Trampling of amphibian habitat (wetlands) by overabundant, native deer populations: Overpopulation of deer can lead to excessive trampling of wetland habitats, which are essential breeding and feeding grounds for amphibians.

The destruction of wetlands can disrupt breeding cycles and result in the loss of suitable habitats for amphibians.

c. Commercial harvesting and use of gonads and legs: This threat is not commonly associated with amphibian decline. While some amphibians are indeed harvested for various purposes (such as food, traditional medicine, or the pet trade), it is not a widespread or major cause of amphibian population declines compared to other threats.

d. Introduced, exotic species (crayfish and fish): Invasive species, including crayfish and fish, can have detrimental effects on native amphibian populations. They can prey on amphibian eggs, larvae, or adults, compete for resources, and alter habitats, leading to declines in amphibian populations.

In summary, while options a, b, and d are known threats associated with amphibian decline, option c (commercial harvesting and use of gonads and legs) is not typically considered a major threat to amphibians.

Explanation:

Children either have blood group B or O thus the probability of a child being either blood group B or O is 50%.

The hormone that does not increase blood glucose levels is insulin.

Insulin is produced by the pancreas and helps to lower blood glucose levels by allowing cells to take up glucose from the bloodstream for energy or storage. In contrast, glucagon, epinephrine, and cortisol all increase blood glucose levels through various mechanisms such as stimulating the breakdown of glycogen in the liver or reducing glucose uptake by cells.

Temperature and available nutrients are two external factors which influence differentiation in plant stem cells .

What is differentiation process ?

It is the process in which meristematic tissues undergo permanent change , which as a result forms the specialized cells in the plant body .

Optimum temperature  and availability of nutrients helps the immature cells to grow into permanent ones . unavailability of these factors restrict the process .

The type of animal used for this testing is sentinel animals, option D is correct.

Sentinel animals are healthy animals that are placed in close proximity to animals being used for research to monitor the presence of microorganisms in the animal facility. These animals are exposed to the same environmental conditions as the research animals and are periodically tested for the presence of microorganisms such as bacteria, viruses, and parasites.

The testing involves collecting serologic (blood), fecal, and other samples from the sentinel animals and analyzing them for the presence of microorganisms. This helps to identify potential contamination in the animal facility and allows for the implementation of appropriate measures to maintain the health of the research animals, option D is correct.

Answer:

Transcription occurs in eukaryotes in a way similar to prokaryotes. However, initiation is more complex, termination does not involve stem-loop structures and transcription is carried out by three enzymes (RNA polymerases I, II and III) each of which transcribes a specific set of genes and functions in a slightly different way.

Explanation:

Answer:

The transcription is the process by which the DNA molecule makes an RNA molecule using the enzyme RNA polymerase and other proteins.

Step-by-step answer:

The mRNA is then used to generate proteins by a process that is called translation which would occur in the cytoplasm. The transcription occurs in the nucleus because the DNA cannot leave the nucleus. which is the center in which the DNA is stored.

The type of selection that makes tall oka trees a better competitor for sunlight over short ones would be directional selection.

It is a kind of natural selection in which individuals with traits at one extreme end of the population are better adapted to the environment.

In this case, tall and short oak trees are at the two extreme ends of the population mean with tall oak trees being able to better competitors for sunlight than the short ones.

The selection is, thus, directional, towards the tall trees rather than the average or the short ones.

The vagus nerve, also referred to as the 10th cranial nerve, is the primary pathway via which the parasympathetic fibres of the autonomic nervous system innervate the heart. The medulla oblongata is where the vagus nerve is born.

The SA and AV nodes in the heart are primarily innervated by the parasympathetic nervous system. Vagal efferents also innervate the atrial muscle, but they sparingly innervate the ventricular myocardium.

Sympathetic and vagal fibres innervate the heart. Although there can be a large overlap in the anatomical distribution, the right vagus nerve primarily innervates the SA node whereas the left vagus nerve innervates the AV node.

In the sense of alternation of generations, there are two generations included in a mature pine seed: the sporophyte generation and the gametophyte generation.

The sporophyte generation is the dominant phase in the life cycle of the pine seed, and is characterized by the presence of a multicellular, spore-producing structure, such as a cone or a seed. This structure contains the mature sporophytes, which produce the male or female gametophytes through meiosis.

The gametophyte generation, in turn, is characterized by the presence of tiny, single-celled structures called gametes, which are specialized for reproduction. These gametes eventually give rise to the next generation of sporophytes.

The alternation of generations is a fundamental aspect of the life cycle of many plants, including pines, and is crucial for their survival and reproduction. The presence of two generations, each with distinct characteristics and functions, allows for efficient production and dispersal of offspring, ensuring the continuation of the species over time.
