Turnover rate of trabecular bone significantly faster than cortical bone. True or False.

Answers

Answer 1

The statement "Turnover rate of trabecular bone is significantly faster than cortical bone" is true. The bone in the human skeleton is composed of two types of tissues: trabecular and cortical bone.

What is bone turnover rate?

Bone turnover rate refers to the cycle of bone resorption, bone formation, and mineralization that occurs in bone tissue throughout life. The metabolic activity of bone tissue is also referred to as the "bone remodeling cycle."Bone remodeling ensures that bone tissue is maintained and renewed throughout life.

In adult bones, bone resorption and bone formation occur at the same time, with a neutral balance between the two processes.However, the turnover rate of trabecular bone is considerably faster than that of cortical bone. This is due to differences in the microstructure and bone composition of each type of tissue. As a result, trabecular bone undergoes more frequent cycles of resorption and formation than cortical bone.

When a particular gene product is required at a particular time or in a particular tissue, transcription takes place. Most of the time, transcription only copies one strand of DNA. The resulting RNA molecules are single-stranded messenger RNAs (mRNAs), and this is referred to as the template strand.

Why is transcription required to take place in the nucleus?

Eukaryotes store DNA in the nucleus, so transcription takes place there rather than in the cytoplasm. Prokaryotes lack a nucleus and store their DNA in the cytoplasm. As a result, transcription can also take place in the cytoplasm. However, DNA is located in the nucleus of eukaryotes.

Determining whether banner-tailed kangaroo rats possess circadian activity rhythms would require:

Answers

To determine whether banner-tailed kangaroo rats possess circadian activity rhythms, a study must be conducted to measure the animals' activity throughout a 24-hour period.

This can be done by using a procedure called actimetry, which measures an animal's activity at periodic intervals, such as hourly or every 15 minutes. This can be accomplished in the laboratory by fitting the animals with activity monitors, or in the field where cameras or infrared sensors can detect their movement.

Researchers can collect data across weeks or months to build up an activity pattern and look for evidence of a rhythm in the animals’ activity that follows a 24-hour cycle. If the activity pattern consistently peaks and falls in a 24-hour cycle, then the banner-tailed kangaroo rats can be concluded to possess a circadian activity rhythm.

d: the side of the stem away from the light

Answers

In the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.

What is auxins?

Auxins are a class of plant hormones that are involved in many aspects of plant growth and development, including phototropism, which is the ability of a plant to bend and grow toward a light source. When a plant is exposed to light from one direction, auxins migrate from the light side of the stem to the shaded side, causing the cells on the shaded side to elongate more rapidly than the cells on the light side. This differential growth results in the bending of the stem toward the light. The concentration of auxins is highest on the shaded side of the stem, where they accumulate due to their movement away from the light. Therefore, in the stem of a plant that is bending toward the light, auxins are most concentrated in the side of the stem away from the light.

using what you know about the structure of DNA
explain why this placement is crucial to separating the fragments

Answers

Using what you know about the structure of DNA, explain why the placement of positive and negative electrodes during gel electrophoresis is crucial to separating the fragments.

The placement of positive and negative electrodes during gel electrophoresis is crucial to separating the fragments as it allows the movement of charged components of the DNA to the appropriate electrodes.

The deoxyribonucleic acid (DNA) is the nucleic acid in the cells of living organisms which is used to store hereditary information of that organism.

The DNA molecule is made up of two strands (fragments) that curve spirally to form a double helix structure.

The gel electrophoresis is a method that can be used to study DNA through the movement of charged molecules through a gel when electric current passes through it.

The placement of a positive and a negative electrode allows the movement of charged components of the DNA to the appropriate electrodes.

Thus, the phosphate groups on the backbone of DNA molecules which are negatively charged would migrate to the positive electrode of the gel electrophoresis since unlike charges attract.

Which compound can only be made if it has access to magnesium ions?

Answers

Answer:

Hope it helps

Explanation:

Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.

Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.

DNA fingerprinting is a laboratory technique used to identify an individual based on their unique DNA pattern. It involves analyzing specific regions of DNA called "variable number tandem repeats" (VNTRs) that vary in length among individuals. By comparing the VNTRs of a person's DNA sample to a reference sample, such as a database, the likelihood of a match can be determined.

DNA fingerprinting is used in forensic science to solve crimes, in paternity testing to determine biological relationships, and in medical research to identify genetic disorders. The high degree of accuracy and reproducibility of the method has made it a valuable tool in various fields.

Explanation:

The variation brings on the sickness. A strong body of scientific evidence exists to link the disease with the gene variation. These variations are frequently called genetic mutations.

What genetic mutation causes strain's pathogen to develop?

The majority of pathogens' evolution is driven by genetic mutation and recombination, which produce the genetic variants on which selection relies.

Plant pathogen populations primarily produce new alleles through mutation. In clonal lineages, it is also the source of novel alleles that give rise to novel genotypes, including novel pathotypes.

Due to genetic mutations and the fact that fewer mutations are produced in small populations, there are fewer alleles present.

Weaponry of a Gray-bellied caenolestid

Answers

The Gray-bellied caenolestid is a tiny marsupial native to the high-altitude regions of South America's Andes. While it lacks specialised weapons, it has adapted physical and behavioural characteristics that assist its survival. Here are several distinguishing features of the Gray-bellied caenolestid:

It has sharp, pointed teeth that enable it to consume insects, worms, and other small invertebrates with efficiency.It has sharp claws on its feet for digging burrows and seeking for food in leaf litter and soil. These talons are not designed for combat, but rather mobility and feeding.

It is well-adapted to its high-altitude habitat. It has a dense fur coat that allows it to withstand frigid temperatures and a compact, well-insulated body. The caenolestid's fur is typically grey or brown, allowing it to merge in with its surroundings and remain unnoticed.

It is important to observe that the caenolestid is not typically aggressive or combative. Its survival strategy focuses primarily on avoiding conflict and using its natural adaptations for evasion and concealment.

how does a single-detector flat-panel unit differ from a multi-detector flat-panel unit

Answers

A single-detector flat-panel unit has only one detector that captures the X-ray image, whereas a multi-detector flat-panel unit has multiple detectors that capture the X-ray image simultaneously. This allows for a faster scan time and improved image quality. Additionally, multi-detector units can capture images from multiple angles, which is useful in procedures such as CT scans.

A single-detector flat-panel unit and a multi-detector flat-panel unit are both types of digital imaging systems used in medical and industrial applications. The key difference between them lies in the number of detectors used for capturing images. A single-detector flat-panel unit uses one detector to capture images, resulting in a simpler design and potentially lower cost. However, it may have slower image acquisition times and lower resolution compared to a multi-detector unit.A multi-detector flat-panel unit employs multiple detectors, allowing for faster image acquisition and improved image quality. This can be especially beneficial in applications where high resolution and quick image capture are essential.

The statement which is true about enzymes is: Enzymes are re-useable and can be used more than once in a chemical reaction.

In the field of science, we define enzymes as biological catalysts that speed up a reaction.

Enzymes lower the activation energy for a reaction in order to speed it up. An enzyme can be used over and over again in a chemical reaction because the enzyme remains unchanged in a reaction.

All enzymes are proteins. Enzymes are substrate specific as they have a special site, known as an active site, where a particular substrate can fit. Hence, a particular enzyme will function as a catalyst for a specific reaction only.

The trouble with him was that he was without imagination. He was quick and alert in the things of life, but only in the things, and not in the significances. Fifty degrees below zero meant eighty-odd degrees of frost. Such fact impressed him as being cold and uncomfortable, and that was all. It did not lead him to meditate upon his frailty as a creature of temperature, and upon man's frailty in general, able only to live within certain narrow limits of heat and cold; and from there on it did not lead him to the conjectural field of immortality and man's place in the universe. Fifty degrees below zero stood for a bite of frost that hurt and that must be guarded against by the use of mittens, ear-flaps, warm moccasins, and thick socks. Fifty degrees below zero was to him just precisely fifty degrees below zero. That there should be anything more to it than that was a thought that never entered his head.As he turned to go on, he spat speculatively. There was a sharp, explosive crackle that startled him. He spat again. And again, in the air, before it could fall to the snow, the spittle crackled. He knew that at fifty below spittle crackled on the snow, but this spittle had crackled in the air.
