An impression left behind by an organism being pressed into soft sediment is called a mold. When minerals fill that void, the resulting fossil is called a cast fossil.

A cast fossil is a type of fossil that forms when a mold is filled with sediment or minerals that harden and form a replica of the original organism. Mold is created when an organism's remains are buried in sediment and the soft tissues decay, leaving an impression or cavity in the sediment. The cast fossil is the opposite of a mold fossil, which is an impression of the organism. That is why cast fossil is also often referred to as reverse mold fossil.

Cast fossils can provide important information about the size, shape, and structure of the original organism, and are valuable for studying the history of life on Earth.

A vesicovaginal fistula is an abnormal opening between the bladder and the vagina that allows the constant involuntary flow of urine from the bladder into the vagina.

An improper connection between the bladder and vagina known as a vesicovaginal fistula causes constant urine leakage via the vagina. The most frequent cause of this illness is gynecological and obstetrical damage. Gynecological surgery is the most frequent cause of vesicovaginal fistula in the developed world. The most frequent cause in North America is bladder damage sustained after a hysterectomy.

Vesicovaginal fistulas are most frequently caused by obstructed labor with pressure necrosis as a result of poor nations. Since the majority of vesicovaginal fistulae require permanent surgical care, the diagnostic workup should be thorough. For successful management, the use of timing, approach, graft usage, postoperative management, and surgical expertise must be optimized. Recurrent fistula formation is the most common side effect of vesicovaginal fistula surgery.

An alternation of generations is a phenomenon commonly found in the life cycle of plants.

An alternation of generations is a phenomenon commonly found in the life cycle of plants. It involves the alternation between two distinct phases, the haploid phase, where there is only one set of chromosomes, and the diploid phase, where there are two sets of chromosomes. The haploid phase is represented by the gametophyte, which produces gametes (reproductive cells) through mitosis. The gametes, one from each parent, unite during fertilization to form a diploid zygote.
The diploid phase is represented by the sporophyte, which produces spores (asexual reproductive cells) through meiosis. The spores are dispersed and develop into haploid gametophytes, restarting the cycle. During the haploid phase, a structure called the gametangia forms, which produces gametes. In the diploid phase, a structure called the sporangia forms, which produces spores. It's important to note that the genetic material in both phases is the same; it's just organized differently. The gametophyte has half the genetic material (one set of chromosomes) while the sporophyte has a full set of chromosomes (two sets). Chromosomes are the structures that carry genetic information and are found within the nucleus of a cell.

1. Rate of southern movement of the plate = 2 cm/year.

In 4000 years, the plate will move a distance of 4000 years * 2 cm/year = 8000 meters

Therefore, the plate will move a distance of 8000 meters south in 4000 years.

2. Wegener in supporting his theory of continental drift used fossils, geologic and glacial evidences. He compared the fossils found in different continents and argued that the presence of fossils of certain animal fossils such as the Lystrosaurus which are found in antarctica, India and South Africa indicates that the continents drifted apart as the Lystrosaurus could not have swam across the ocean to get to these different continents. Also, using geologic evidence by comparing rock structures on opposite sides of the Atlantic ocean, he determined that there were similarities between the rock strata of the Karroo system of South africa with the Santa Carina system in Brazil.

True , Lactase breaks down lactose into the monosaccharides galactose and glucose

Lactose intolerance occurs when your small intestine doesn't produce enough of an enzyme (lactase) to digest milk sugar (lactose). Normally, lactase turns milk sugar into two simple sugars — glucose and galactose — which are absorbed into the bloodstream through the intestinal lining. If you're lactase deficient, lactose in your food moves into the colon instead of being processed and absorbed. In the colon, normal bacteria interact with undigested lactose, causing the signs and symptoms of lactose intolerance. Lactose digestion occurs in the small intestine with the help of the enzyme known as lactase. Lactase breaks down lactose into the monosaccharides galactose and glucose, which makes them available for absorption. Glucose ultimately gets taken up by our cells with the help of insulin. Galactose is transported to the liver, where it is turned into glucose for use in energy production.

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

The mechanism by which alanine inhibits pyruvate kinase activity is Alanine binds to an allosteric site of the enzyme, changing the shape of the enzyme's active site.

The correct option is 1.

Pyruvate kinase is an enzyme involved in the glycolytic pathway, which converts glucose to pyruvate.

Alanine is a product of the alanine transaminase reaction, which is also involved in amino acid metabolism. Alanine is known to inhibit pyruvate kinase activity, thereby reducing the rate of glycolysis.

Alanine is an allosteric inhibitor of pyruvate kinase. It binds to an allosteric site on the enzyme, which is a site other than the active site.

The binding of alanine induces a conformational change in the enzyme, which changes the shape of the enzyme's active site, making it less favorable for substrate binding. As a result, the enzyme's activity is inhibited, and the rate of glycolysis is reduced.
