The collagen-rich ________ limits expansion of the nucleus pulposus when the spine is compressed.

Answers

Answer 1

The collagen-rich annulus fibrosus limits expansion of the nucleus pulposus when the spine is compressed.

Annulus fibrosus is the tough cartilaginous tissue that surrounds the sift nucleus pulposus. These two structures together form the intervertebral disc. It is responsible for the stability of the spine during rotation. The toughness of the annulus fibrosus is due to the collagen fibers.

Spine is the backbone present in the vertebrates. In humans it is formed of 5 different types of bones that are total 33 in number. The spine in necessary to maintain the posture of the body and keep it erect. It begins from the base of the skull and extends till the hipbone.

The trp and lac operons are regulated in various ways. how do bacteria regulate transcription of these operons?

Answers

Operon is not transcribed:

-lac operon: lactose absent

-trp operon: tryptophan present

Positive control transcription of Operon does not speed it up:

Lactose and glucose are present, -lac operon

Tryptophan is lacking in the -trp operon.

Operon is transcribed quickly through positive control:

-lac operon: lactose present, glucose not

Only negative control is used to regulate the trp operon. The operon genes are not transcribed when tryptophan is present.

Both positive control and negative control are used to control the lac operon.

Negative control: Transcription is inhibited when lactose is missing due to the activity of the repressor protein.

—The repressor protein is deactivated and transcription is triggered when lactose is present.

Positive control: —In the absence of glucose, another regulatory protein (CAP) attaches to the lac operon's promoter, speeding up transcription in the presence of lactose.

What is the hybridization of the central atom in the xenon tetrafluoride molecule?

Answers

The central atom has 6 electron pairs out of which two are lone pair electrons. The hybridization in Xenon is sp3 d2 because there is a migration of two electrons of p to d orbital which results in the formation of a sigma bond with F.

What is meant by hybridization?

Whenever two atomic orbitals in a molecule merge to generate a hybrid orbital, the energy of the orbitals of the single atoms is redistributed to give orbitals of equivalent energy. Hybridization is the name of this procedure. In the hybridization process, atomic orbitals with similar energies are mixed together; this often includes the fusion of two s orbitals, two p orbitals, or the mixing of an s orbital with a p orbital or a d orbital.

Hybrid orbitals are the novel orbitals that result from this process. However, hybrid orbitals are also very helpful in describing the geometry of molecules and the characteristics of atomic bonds. Let's immediately examine the example of an atom of carbon. This atom creates four single bonds in which three valence-shell p orbitals and one valence-shell s orbital combine.

The result of this combination is the creation of four comparable sp3 mixes. Around the carbon, which is bound to four distinct atoms, they will be arranged in a tetrahedral pattern.

Therefore, the molecule has sp3 d2 hybridization.

Answers

The correct answer is four cycles are  (1) The Water Cycle or Hydrologic Cycle (2) The Carbon Cycle (3) The Nitrogen Cycle (4) The Oxygen Cycle.

The hydrologic cycle is the continuous movement of water in the Earth-Atmosphere system. The water cycle is defined as the movement of water from the ground to the atmosphere and back again.

The carbon cycle describes the movement of carbon from the atmosphere to soils, living creatures, the ocean, and human sources.

The Nitrogen Cycle is a biogeochemical process in which nitrogen is converted into various forms before passing from the atmosphere to the soil to the organism and back into the atmosphere.

The entire cycle can be summarized as follows: the oxygen cycle begins with photosynthesis in the presence of sunlight, releases oxygen back into the atmosphere, which humans and animals breathe in oxygen and breathe out carbon dioxide, and then links back to the process of photosynthesis.

The rate of photosynthesis rises as light intensity does (point B on the graph). Thus, there is a greater intake of carbon dioxide. This rise in carbon dioxide uptake is depicted on the graph.

What effect of light intensity on the rate of photosynthesis?

As long as other variables are abundant, photosynthesis will proceed at a faster pace as light intensity rises. Another element will eventually become scarce as the rate rises.

Water and carbon dioxide are converted by photosynthetic pigments using light energy into carbohydrates and oxygen.

Answers

Answer:

Some bacteria, such as those of the genera mycobacterium and nocardia, not effectively stained with the gram stain because they have too much peptidoglycan in their cell walls.

Explanation:

Across most types of bacteria, the cytoplasmic membranes is encased in a hard material called peptidoglycan. It helps maintain cell shape all across the life cycle and shields bacterial cells against environmental stress. The production of peptidoglycan has a significant role in controlling bacterial cell division. The bacterial cell wall's peptidoglycan plays a structural role by providing structural support and balancing the cytoplasm's osmolarity. Additionally, peptidoglycan participates in binary fission throughout bacterial cell division. Christian Gram, a microbiologist, developed a test in 1884 which might identify whether a bacterium possessed a strong, mesh-like membrane known as peptidoglycan. Numerous bacteriophages, eukaryotic, and bacteria all generate peptididoglycan hydrolases.
