Pia mater (soft inner layer of the dural membrane system) The pia mater, which contains vessels, is the innermost layer of the three meningeal membranes. ... Furthermore, it creates the choroid plexus, a network of bold vessels, which enter the brain ventricles and produce the cerebrospinal fluid (CSF).

The pia mater, a delicate layer rich in blood vessels, covers the brain and spinal cord. Conversely, ventricles are fluid-filled compartments where cerebrospinal fluid (CSF) is produced by the choroid plexus. Both pia mater and ventricles are essential parts of the brain's nourishing and protective mechanisms.

The pia mater is a thin, delicate layer that directly covers the brain and spinal cord. It is rich in blood vessels that nourish the central nervous tissue. The ventricles, on the other hand, are fluid-filled compartments in the central nervous system (CNS) where a tissue called the choroid plexus produces cerebrospinal fluid (CSF).

The pia mater and the ventricles are part of the brain's protective and nourishing mechanisms. The brain floats in CSF, which guards it like a cushion, helping to make it neutrally buoyant. Moreover, the CSF also circulates chemical substances throughout the brain and into the spinal cord.

The ventricles and their choroid plexuses are a key component of the circulation of cerebrospinal fluid, which also contributes to waste removal from the CNS. The choroid plexuses are structures where ependymal cells line blood capillaries filtering blood to produce CSF in the four ventricles of the brain.

Answer:

Mycelium  is the part of fungus consisting of a mass of branching thread like hyphae. It makes up the body of the fungus living on a particular substrate. Mycelium when dried can be a strong material which can be water, fire and mold resistant. Mycologist Philip Ross found out that dried mycelium can be grown and used for making building blocks. These mycelium bricks are organic and compostable. Their consistency is also stronger than concrete bricks. These mycelium bricks can be painted. These are bulletproof and can withstand extreme temperatures. When their use is over they can be composted therefore, biodegradable and does not harm nature in anyway. Hence, they are eco-friendly. Their durability and strong structural construct can be used for replacing them with other chemically synthesized building material. A five year plan with eco-friendly mycelium bricks can result when fungus mycelium bricks is considered only  mandatory material for building construction purpose. Some durable and high tensile strength material if added in them can improve their quality provided that they are completely compostable.

The number of the offspring produced in the dihybrid cross is 192.

In dihybrid cross, the ratio of the plants obtained in the F2 generation is 9: 3: 3: 1.

Thus, yellow round offspring is 9/16, green round offspring is 3/16, yellow wrinkled offspring is 3/16, and green wrinkled offspring is 1/16.

Thus, the number of green and round offspring produced can be calculated as:

Green round seed = 3/16

= 3/16 × 192

= 576/16

= 36

Thus, out of 192 peas, 36 will be green and round.

Suppose the parents indicated in the interactive produced 192 peas. Then the expected number of green and round offspring is thirty-six.

Further Explanation:

A recessive trait is defined as a trait that gets expressed by an individual when they show a homozygous recessive condition. This means that if an individual showing a recessive trait will definitely possess both the recessive alleles for that trait as a recessive trait gets concealed by the presence of allele for the dominant trait.

The monohybrid cross is an experiment between the first generation organisms that differ in only one trait. The resultant ratio of the f-1 generation is 1:2:1. A Punnett square mainly used to predict the possible genetic outcomes of a monohybrid cross. Mainly the dihybrid cross occurs when there are two traits are present.

The total number of offspring produced in the dihybrid cross is 192. In the dihybrid cross, the ratio of the plants obtained in the F-2 generation is 9:3:3:1.

Now, yellow round offspring is 9/16

Green round offspring is 3/16

Yellow wrinkled offspring is 3/16

Green wrinkled offspring is 1/16.

Thus, the number of green and round offspring produced can be calculated as:

Green round seed = 3/16

= 3/16 × 192

=576/16

= 36

Thus, out of 192 peas, 36 will be green and round.

The activity of a sample is determined in terms of the number of nuclear disintegrations in a second. The Curie or Ci is a common unit for activity measurement. Bq or Becquerel refers to the SI unit for radiation activity measurement.  

The activity of K-40 in 70 kg human body is 120 nCi

The relationship between Curie and Becquerel are as follows:  

1Ci = 3.7 × 10¹⁰ Bq

1nCi = 37 Bq

Thus, 120 nCi × 37 Bq / 1nCi = 4.4 × 10³ Bq.  

Hence, the activity of K-40 in a 70 Kg human body is 4.4 × 10³ Bq .

The activity of K-40 in a 70 kg human body, given as 120 nCi, is equivalent to 4.44 × 10⁴ becquerels when converted using the appropriate conversion factors.

The activity of K-40 in a 70 kg human body is estimated to be 120 nCi. To convert this activity to becquerels, we use the conversion rate where 1 Ci = 3.70 × 10¹⁰ Bq. Therefore, we first convert nanocuries (nCi) to curies (Ci) by dividing by 1 billion (since 1 nCi = 10⁻¹ Ci), and then multiply by the conversion factor.

Here is the step-by-step conversion:

The activity of K-40 in a 70 kg human body is therefore 4.44 × 10⁴ becquerels.

This evidence suggest that all three living creatures that are mentioned have a common ancestor, even though they have been split into different types of groups of living organism millions of years ago.

Science suggests that all of the living organisms on the planet have a common ancestor. Since we are talking about a common ancestor that lived few hundred million years ago, the living organisms split into different groups, and they do not resemble each other nowadays. The fruit fly is an insect, and the humans and mice are mammals, so they are into totally different groups, and it is easy to see by the genetic evidence that they are very distantly related, but the humans and mice are much more closely related because they belong to the same super family, and their connection is much more recent.

Explanation:

The correct answer is: B. A person spends one hour each day under the ultraviolet rays of a tanning bed.

The relationships between  ultraviolet (UV) light and skin cancer are highly positive because it has been shown that indoor tanning bed use represents an avoidable risk factor for melanoma and non-melanoma skin cancer. UV light is a form of radiation that causes mutations in DNA by causing the chemical changes that alter the shape of the DNA. So, UV light is a potent mutagen and thus, tanning bed (source of UV light) can cause damage to the DNA in the surface layer of your skin after repeated or prolonged exposure. This might increase the risk for skin cancer.

Explanation:

Sugar Glucose is transported by Active Transport from the gut into Intestinal epithelial cells.

Hope this helps.

Davismr00~

Answer:

Transport active.

Explanation:

Glucose is the main source of cellular energy. It is captured by most cells in the body through carrier proteins present in the plasma membrane in favor of their concentration gradient. On the other hand, in intestinal epithelial cells and renal tubules, glucose is captured against its concentration gradient using apical membrane transport proteins and then exits the cell through the basement membrane to enter the bloodstream, in favor of its concentration gradient using membrane carriers known as GLUT's.

Glucose uptake by intestinal epithelial cells always occurs by active transport because it uses a membrane protein in transport even when it is in favor of the concentration gradient.

Co-transport system of intestinal epithelial cells. Glucose then moves into the blood through the permease in the membrane between the cell and the blood. Thus, ATP is used as an energy source to drive Na+ out of the cell, resulting in glucose transport from the intestine to the blood.

Final answer:

Glucose is transported into intestinal epithelial cells via secondary active transport involving the SGLT1 cotransporter, which uses the energy from a sodium ion gradient maintained by the Na+/K+-ATPase pump. This pump exchanges sodium for potassium with ATP hydrolysis, allowing glucose to accumulate in the cell and then diffuse into the bloodstream through the GLUT2 transporter.

Explanation:

Co-transport of glucose into the intestinal epithelial cells is facilitated by a mechanism known as secondary active transport. This process involves the sodium-glucose cotransporter 1 (SGLT1), which simultaneously transports glucose along with sodium ions into the cell against the glucose concentration gradient. The energy for this movement is derived from the sodium ion gradient established by the Na+/K+-ATPase, which pumps sodium out of the enterocyte into the bloodstream in exchange for potassium ions, utilizing ATP. Once inside the cell, glucose then passively diffuses out into the bloodstream through the GLUT2 transporter located in the basolateral membrane. As this transport requires ATP to maintain the sodium gradient, it is termed active transport.

It is essential to maintain a low concentration of Na+ inside the cell to continue this process. Hence, the Na+/K+-ATPase pump expels Na+ ions out of the cell into the blood plasma, maintaining the gradient that powers the SGLT1-mediated glucose transport from the lumen of the gut into the cell.

Answer:

Or i think its capillary action

Explanation:

Capillary action (sometimes capillarity, capillary motion, capillary effect, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper and plaster, in some non-porous materials such as sand and liquefied carbon fiber, or in a biological cell. It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion within the liquid) and adhesive forces between the liquid and container wall act to propel the liquid.

The answer is limestone.  Hope I helped you out!

Answer:

Limestone

Explanation:

Marble is a metamorphic rock which is formed, when the sedimentary rock named limestone is subjected to extreme pressure and temperature condition. During this process of metamorphism, the calcite minerals present in the rock limestone undergoes the process of re-crystallization, thereby producing a much more denser and higher grade rock where the calcite crystals alters into more forcibly equigranular crystals.

This is how limestone after going through the process of metamorphism, changes into a metamorphic rock named marble.
