The mandible (D) is the bone that does not contain air sinuses.

Bones are hard mineral structures that make up the skeleton of vertebrates. They offer both the framework for the body and protection for delicate internal organs such as the brain, spinal cord, and heart.

The air-filled spaces in the bones of the skull are known as air sinuses. The sinuses that are found within the facial bones are referred to as the paranasal sinuses. The sinuses have a number of functions, including decreasing the overall weight of the skull, humidifying and heating the air entering the body, and resonating during speech to amplify the sound.

Based on the given options, the answer would be option D) the mandible. The mandible is a facial bone, but it does not contain air sinuses. The other three bones listed - the frontal bone, the ethmoid, and the maxilla - all include air sinuses.

When two species interact within a habitat, competitive exclusion can be observed when both species depend on same limiting resource and one species is better competitor for that resource.

what is competitive exclusion principle?

The principle of competitive exclusion states that two species competing for the same limiting resource cannot coexist at constant population values. If one species has the slightest advantage over another, the one with the advantage will dominate in the long run. This either leads to the extinction of the weaker competitor or to an evolutionary or behavioral shift to a different ecological niche. Competitive exclusion is rarely observed in natural ecosystems.

hence, if two species are inhabiting in same area then these will have same food requirement then competitive exclusion can be seen.

The statement that is not true about human childhood is that it is an extremely short stage of human life, option (d) is correct.

Human childhood is characterized by a prolonged period of dependency and development, which sets it apart from other species. Unlike many animals, humans have a longer childhood, allowing for extensive learning and socialization. Childhood is indeed crucial for human learning, as it is during this phase that individuals acquire essential cognitive, emotional, and social skills.

Humans have notably longer childhoods compared to other primates. Childhood is generally defined as the period between infancy and puberty, rather than specifically between weaning and puberty and human parents do continue to provide nourishment and care for their offspring during childhood, option (d) is correct.

Eukaryotes can splice, whereas bacteria cannot, hence if you wish to introduce a eukaryotic gene into a bacterium, you must utilize a modified version of the gene that already has the introns removed.

To get around these problems, it may be possible to produce recombinant proteins that closely mimic natural eukaryotic proteins by co-expressing modified mammalian enzymes such protein methylases and acetylases with their substrates from one or two different plasmid vectors in the same E. coli.

The two most widely used techniques for bacterial transformation are electroporation of electrocompetent cells and heat shock of chemically prepared competent cells (chemical transformation).

The name given to the cells produced at the end of meiosis 1 in females is secondary oocytes.

Secondary oocytes, also known as secondary follicles, are a stage of egg cell development that occurs during the menstrual cycle in women. These cells are formed after the primary oocyte undergoes meiosis I, which produces two cells: a secondary oocyte and a polar body.

The secondary oocyte is larger than the polar body and contains most of the cytoplasm and organelles of the original cell. It is surrounded by a layer of cells called the corona radiata and a protective coating called the zona pellucida.

If the secondary oocyte is fertilized by a sperm cell, it undergoes meiosis II and forms a mature ovum (or egg cell) and another polar body. The mature ovum is then capable of being fertilized by a sperm cell and developing into an embryo. If the secondary oocyte is not fertilized, it will degenerate and be expelled from the body during menstruation.

The process of evolution that involves a change in the DNA sequence that leads to evolutionary change is called a mutation.

A mutation is a sudden and lasting alteration in the DNA sequence that can influence genetic variation. Changes in the DNA sequence can influence phenotype, which may or may not have an effect on an organism's fitness. Mutations occur spontaneously, either from errors in DNA replication or from exposure to mutagenic agents. Mutations may happen in either coding or non-coding regions of the DNA, and they can be either silent or expressed.

Evolution is a natural process that results in the gradual change of inherited characteristics in populations over generations. It is the process of alteration in the inherited characteristics of species over successive generations. In other words, it is the process of gradual changes that happen to species over time as they adapt to their environments. It can be defined as a change in the gene frequency in a population over time.

Types of Evolution 1. Natural Selection 2. Genetic Drift 3. Gene Flow 4. Mutation 5. Non-Random Mating 6. Admixture 7. Mutation Pressure 8. Genetic Draft 9. Bottleneck and Founder Effect 10.

Ya antes del fin del siglo XIX Ehrlich había usado el término "complemento" para designar la actividad del suero que podía complementar la capacidad de los anticuerpos específicos de lisar bacterias. Pero es Jules Bordet quien descubre (1895) este componente, caracterizado frente a los anticuerpos por su termolabilidad. En 1907 Ferrata comienza a caracterizar algunos de sus componentes recurriendo a métodos de diálisis. Por motivos meramente cronológicos, los componentes iban recibiendo denominaciones a base de números tras la letra "C" conforme se iban descubriendo. Por esta razón, su orden de actuación no guarda en general relación con su nomenclatura.

Answer:

A virus injects its genetic material into the host cell, copies itself, and then forms new viruses that burst out of the host cell.

Explanation:

There are two cycles of viral replication.

1. Lytic

2. Lysogenic

The lytic cycle involves the destruction of the cell to release viral particles.

The lysogenic cycle incorporates the DNA into the host's genome and the DNA is replicated when the cell replicates. This cycle can turn into the lytic cycle in a process called induction.

The embryonic stage lasts for two months following conception, starting at the conclusion of the germinal stage. Currently, the growing mass of cells is referred to as an embryo. At this point, the embryo becomes extremely delicate as all the major organs mature.

The body grows and the development of the organs happens throughout the prenatal developmental stage. Fertilization is the beginning, and birth is the finish.

There are several changes in the body that take place throughout this phase of growth. Fetal circulation, fetal breathing, and fetal swallowing are just a few of the various developmental phases that the fetus goes through.

The tympanic membrane closes the inner end of the auditory canal is the correct statement.

Option (c) is correct.

The tympanic membrane, commonly known as the eardrum, is a thin, cone-shaped membrane located at the inner end of the auditory canal. It separates the external ear from the middle ear and forms the boundary between the outer and middle ear. When sound waves enter the ear through the auditory canal, they cause the tympanic membrane to vibrate.

These vibrations are then transmitted to the ossicles (three small bones in the middle ear), which amplify and transmit the sound further into the inner ear. The function of the tympanic membrane is to convert sound energy into mechanical vibrations, allowing sound to be efficiently transmitted from the outer ear to the middle ear.

Therefore, option c, stating that the tympanic membrane closes the inner end of the auditory canal, is the correct statement.

The young of oviparous animals develop briefly in their mother's body, nourished by egg yolk and by nutrients that diffuse from the mother's tissues.

Oviparous animals are those that lay eggs, and their eggs contain a yolk that provides a source of nutrients for the developing embryo. In some species of oviparous animals, such as some fish and reptiles, the eggs are laid outside the mother's body and the embryo develops and hatches outside the mother's body.

However, in some oviparous animals, such as some sharks and some species of reptiles, the eggs develop inside the mother's body for a period of time before being laid. During this time, the developing embryo is nourished by the yolk and by nutrients that diffuse from the mother's tissues.

This type of development is different from viviparous animals, which give birth to live young that have been nourished by nutrients from the mother's blood during gestation.

At rest, a greater portion of cardiac output is focused on the liver, kidneys, and gastrointestinal tract. A greater portion of the cardiac output is focused on the skeletal muscles during exercising.

At rest, the major bodily organs receive a very even distribution of the cardiac output. This indicates that each organ gets enough blood, oxygen, and nourishment.

The metabolic requirements of each organ dictate the distribution of cardiac output during rest, with the brain receiving approximately 15-20% of cardiac output, the heart receiving approximately 4-5%, and the kidneys, liver, and gastrointestinal system each receiving 20-25%.

The distribution of cardiac output alters during exercise to accommodate the body's increasing metabolic demands. A bigger volume of blood is pumped to the organs each minute as a result of an increase in cardiac output, which is brought on by an increase in heart rate.
