1) Plates separate and new seabed is created. 2) Plates collide, obduction occurs, and inland mountain chains are created. 3) Plates collide, subduction occurs, and mountain volcanic chains are created. 4) Plates collide, subduction occurs, and volcanic arcs are created. 5) Plates slide, no material is created, and displacements occur.
What are the three types of boundaries?
I. Divergent
New crust is created by the rising molten materials coming from the mantle.
Two plates separate, and the stream of hot material creates a new seabed between them. It occurs in an expansion of the sea bottom.
As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge.
An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.
II. Convergent.
When two plates move forward to each other, they end up colliding and causing the deformation of one or both plates.
Three possible collisions might occur,
Two oceanic plates might collide ⇒ subduction
The thickest plate subduces and causes a deformation on the other plate edge, creating an oceanic trench.
Hot magma rises to the surface by these trenches and creates volcanoes on the superior plate. These volcanoes can be underwater or can emerge from the ocean surface, forming island arcs or an insular volcanic arc.
Japanese islands and the Philippines are examples.
Two continental plates might collide ⇒ obductionBoth plates are too light to subduce (equally dense), so neither of them sinks under the other one.
Occurs a vertical deformation on both plates' edges, which remain attached by a suture area. The result is an inland mountain chain formation.
The highest mountains on the Earth were created by this process. Examples of these are Alpes, Urales, and Himalayan mountains.
Oceanic plate and continental plates collide ⇒ SubductionThe oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The result is the formation of mountain chains or volvanic chains due to the deformation caused on the continental plate edge.
The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur on the continental plate.
No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.
The San Andrés fault is an example of these plate ridges.
1. Divergent Boundary
Plates separate and new seabed is created.
2. Continental-Continental Convergent Boundary
Plates collide, obduction occurs, and inland mountain chains are created.
3. Continental-Oceanic Convergent Boundary
Plates collide, subduction occurs, and mountain volcanic chains are created.
4. Oceanic-Oceanic Convergent Boundary
Plates collide, subduction occurs, and volcanic arcs are created.
5. Transform Fault Boundary
Plates slide, no material is created or destroied, and displacements occur.

A. Do germinating peas release oxygen in the process of respiration?
B. Do germinating peas release water in the process of photosynthesis?
C. Do germinating peas absorb water in the process of photosynthesis?
D. Do germinating peas release carbon dioxide in the process of respiration?
The increase in water level shows that respiration in the conical flask is causing gram seeds to germinate, which releases carbon dioxide. Thus, option D is correct.
What gases are released by germinating peas?The KOH solution in the little test tube absorbs the CO2 that the germination of the seeds in the conical flask releases during breathing.
As a result, a small vacuum is created inside the flask, forcing the water up the delivery tube. It demonstrates that seeds that are germination carbon dioxide during respiration.
By mixing glucose with oxygen from the air, organisms create energy during the process of respiration. Glucose and oxygen are converted into energy and carbon dioxide during cellular respiration.
During the process of cellular respiration, carbon dioxide is released into the atmosphere.

For children who do not have galactosemia, what are their possible genotypes for this trait?
The autosomal recessive mode of inheritance for galactosemia. Galactosemia is an autosomal recessive disorder in which one normal gene and one defective gene are present in each parent of a galactosemic child.
Disruptions or a gene cause galactosemia. Galactosemia develops as a result of disruptions or alterations (mutations) in the GALT gene, which leads to a lack of the GALT enzyme. Galactosemia indications, symptoms, and clinical findings result from the abnormal accumulation of molecules connected to galactose in numerous organs of the body. when an enzyme that breaks down galactose is produced by different (mutated) genes. In order to have galactosemia, a kid must inherit two galactosemia genes, one from each parent. Galactose and its derivatives accumulate in the blood when a person has galactosemia. Cells and body parts may be harmed by this.

4. Twenty percent of the air breathed in consists of oxygen. Sixteen percent of the amount of oxygen entering air breathed out, consists of oxygen .Catulate the blood per breath after running.
The air that is breathed in contains oxygen in a concentration of 20% while the air exhaled still contains oxygen in a concentration of 16%. This implies 4% oxygen has been absorbed by the blood cells per breath.
Even though 16% of the oxygen in the air is exhaled, hemoglobin is 100% saturated with oxygen.We only exhale 16% of the oxygen we breathe in because some parts of our lungs are not actively engaged in gas exchange.The conducting parts of the airways that do not take part in the exchange of oxygen and carbon dioxide include the nose, mouth, and windpipe, for instance. They only move air from the atmosphere to the interior of the lungs. The distal-most air sacs, known as the alveoli, where gas exchange takes place, are the functioning parts of the lungs.Therefore, the air from the nose, mouth, and windpipe still contains all of the oxygen when we exhale, and this accounts for the 16% of oxygen that is lost during breathing.

B. The frequency of dominant alleles in the population (p)
C. The percentage of individuals in the population that are heterozygous:
D. Provide an explanation for why so many fish in the lack display the recessive
trait
The predominant allelic frequency is the allelic frequency of the recessive gene, the genotypic frequency of homozygous dominants (p2), genotypic frequency of homozygous recessives (q2), 2pq the genotypic frequency of heterozygotes
These allelic frequencies add up to 1, so p + q = 1. Likewise, the genotypic frequencies add up to 1, so p2 + 2pq + q2 = 1.
q² = 600/680 = 0.882
We can determine the recessive allele if q2 represents the homozygous recessive genotypic frequency. by removing the equation, frequency
q= √0.882 = 0.939
We will receive both homozygous and heterozygous phenotypic frequencies.
p+ q =1
p=0.061
Knowing that 2pq is the heterozygous genotypic frequency, we can quickly compute it by substituting the following terms for:
2pq=2 x 0.061 x 0.939 = 0.115.
Directional selection increases the percentage of people who have one of severe phenotypic characteristics This trait makes people more likely to survive in particular circumstances.

The fingerprint is a mark of the finger skin left on different surfaces. It is called print because it leaves the exact shape and pattern of the skin ridges. This pattern is known as dermatoglyphics.
Dermatoglyphics is significant because
they are unique to each person. What is more, each finger has its own skin ridges pattern. they are permanent and do not change. The pattern is the same throughout the individual's life.
Because of these two characteristics, fingerprints are a reliable tool during a crime scene.
Fingerprints results from oily secretions and sweat produced naturally by the skin. Since these are invisible, they are not detected at simple sight.
The fingerprinting powder is a useful method to detect fingerprints on certain surfaces, making them evident. Once identified, forensics lift the prints from surfaces and take them to the laboratory for further analysis.
Because of finger secretion, oil and sweat react with the powder and make the print visible by contrast. The powder sticks to the secretions but not to the clean background, making dermatoglyphics visible when applied.
