Scientists have not yet determined conclusively whether DNA or RNA was the first nucleic acid that evolved on early Earth. Why does this topic interest scientists?
It is believed that RNA evolved earlier than DNA, but it is still not clear. Therefore, this topic interests scientists.
What is nucleic acid?Nucleic acid is a macromolecule that is a polymer of nucleotide. It is made up of pentose sugar, phosphate group, and nitrogenous bases (purines and pyrimidines) which include adenine, guanine, thymine, uracil, and cytosine.
It is of two types, DNA (deoxyribose nucleic acid) and RNA (ribose nucleic acid). They play a very important role in heredity and protein synthesis in all living organisms. It is found in the cell.
DNA is a double helix, while RNA is a single helical structure. DNA is converted into RNA through the process of transcription and RNA is converted into DNA by reverse transcription. It is believed that RNA evolved earlier than DNA, but it is still not clear. Therefore, this topic interests scientists.

What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

Answer: From the groups stated in the attachment, the group that contains prokaryotic organisims is GROUP 1
Explanation: There are two types of cells,The eukaryotes and the prokaryotes.
The prokaryotes or prokaryotic organisms are those organisms that have just a single cell.in prokaryotic organisms,there is no presence of a distinct nucleus and it's not covered by a nuclear envelope, organelles that are bond by a cell membrane are also absent.
Prokaryotes have a cell wall that helps in the maintainance of cell shape and the prevention of dehydration because it gives an extra or added layer of protection to the cell.
The DNA,that is the genetic material of prokaryotes are not covered by a membrane,hence they move about freely in the cell cytoplasm.
Some prokaryotic organisms known as chemosynthetic prokaryotes produce their own food by getting energy and oxidizing them,these energy are gotten mainly by oxidizing high energy inorganic compounds like ammonia, hydrogen gas and sulphides.

Answer: Hemostasis includes three steps that occur in a rapid sequence:
Explanation: 1) vascular spasm, or vasoconstriction, a brief and intense contraction of blood vessels; (2) formation of a platelet plug; and (3) blood clotting or coagulation, which reinforces the platelet plug with fibrin mesh that acts as a glue to hold the clot.
or:
The Blood Clotting Process
Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.

Polycythemia is a disease which causes an excessive number of red blood cells to be produced. The disease is the result of a faulty gene. How would the flow of blood be affected by this condition?
Answer:
The blood flow would be delayed, since the amount of red blood cells increases the total density of blood volume, which is why the greater the quantity of blood, the thicker the blood will be.
This, as a consequence, could cause thickening of the blood, thus becoming denser, affecting the continuous laminar flow inside the blood vessels, this means that the flow is not unidirectional, but when it is delayed, it produces a kind of micro whirlpools that hinder healing, circulation, oxygenation and stimulate the appearance of deep and superficial clots or thrombosis.
Explanation:
It is important to clarify that the polycythemia which we are talking about is very excessive, very noticeable, unlike the physiological polycythemia that the body does when faced with an increase in height and a decrease in partial pressure of oxygen.
This is important for you to know, because the body when we climb a mountain or climb, or the partial pressures of oxygen decrease in the atmosphere, takes as a compensation mechanism the increase of red blood cells to maintain the oxygenation of the body, but this being PHYSIOLOGICAL is not excessive.
Polycythemia due to genetic failure such as the one we are writing now is a pathology because we are facing an excessive EXCESS of red blood cells, where phenomena of jaundice and hemolysis can also occur due to the great imbalance that is generated in the entire body

The correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic, igneous, lithified, and Compaction.
Igneous rocks are a type of rock that forms from the solidification and crystallization of molten material, known as magma or lava.
Intrusive igneous rocks, also known as plutonic rocks, form when molten magma cools and solidifies beneath the Earth's surface.When molten magma or lava cools slowly, it provides sufficient time for the atoms and molecules within the molten material to arrange themselves in an orderly manner. The process of deposition refers to the settling or accumulation of sediments, which are fragments of rocks, minerals, organic matter, or other particles, onto a surface.Cementation is a process in which minerals in fluid form, often dissolved in groundwater, precipitate and crystallize within the pore spaces of sedimentary materials. During regional metamorphism, large volumes of rock are subjected to significant heat and pressure, typically deep within the Earth's crust. Contact metamorphism, also known as thermal metamorphism, occurs when a rock comes into direct contact with magma or an igneous intrusion.Foliation refers to the parallel alignment of minerals or the development of compositional layering within a metamorphic rock. Volcanic igneous rocks are classified as extrusive igneous rocks because they are formed from lava that has extruded onto the surface.The process of lithification involves the transformation of loose sediments into solid sedimentary rocks.Compaction is a key process in the lithification of sedimentary rocks. It takes place as layers of sediment accumulate over time, and the weight of the overlying sediments exerts pressure on the underlying layers.Thus, the correct blanks are Intrusive, Slow, deposited, cementation, Regional, Contact, Foliation, volcanic igneous, lithified, and Compaction.

What kind of fossil is created when minerals fill in the hollows of animal tracks?
A. Frozen fossils
B. Imprint fossils
C. Amber fossils
D. Cast fossils
Answer: The correct answer to the question is option D
CAST FOSSILS.
Explanation: To understand what a cast fossil really is,let's look at what a fossil is generally.
Fossils are traces of what are formed and left of living things which dates back to a long time ago. Fossils are often found in sedimentary rocks examples; Shales, limestone and sandstone.Fossils are left over animals/plants.
Not all fossils are remains of living things.
There are different types of fossils; FROZEN FOSSILS; When an animal is trapped and freezed as a result of drop in temperature.
IMPRINT FOSSILS; They are prints made and left when animals walk or move over clays,these imprints dries and get covered by other sediments.plants also leave imprint fossils.
AMBER FOSSILS; These are fossils that are formed when tiny insects and bugs become trapped in saps of trees, when these saps dries up,they become hard and and an Amber is formed.(a seminiferous material).
CAST FOSSILS; These are fossils that form as a result of the death of plant,animal or any organism,when this happens,chemical reaction occurs which brings about a degradation in the bones and flesh if the organism,cavities are formed and minerals are deposited in those cavities bringing about a cast which looks like the original form or image of the organism.

T^3=r^2
2. Which of the following are effects of melting sea ice? Select the two correct answers.
The exposed water can radiate more heat to the atmosphere than it could when insulated by the ice cover.
The exposed water reflects back more sunlight than did the ice.
The exposed water absorbs more thermal energy from the sun than did the ice
The exposed water absorbs heat and then sinks, replaced by cooler water.
3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?
The orbital speed of the galaxies in the cluster is slow enough to keep the cluster intact.
Dark matter provides the mass and gravity needed to keep the cluster together.
The orbital speed of the galaxies in the cluster is fast enough to keep the cluster intact.
Baryonic matter provides the mass and gravity needed to keep the cluster together.
Answer:
1. T^2=r^3 ( or T² = r³)
2. "The exposed water reflects back more sunlight than did the ice"
and
"The exposed water absorbs more thermal energy from the sun than did the ice'
3. Dark matter provides the mass and gravity needed to keep the cluster together.
Explanation:
1. Which is the simplified version of Kepler’s third law when one of the planets being compared is Earth?
Kepler's Third law of planetary motion is the ratio of the square of the orbital period of a planet is to the radius of orbit of a planet or those of other planets.
This means that, Kepler's Third law of planetary motion states that the square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.
Mathematically, Kepler's Third last is represented as
T² : r³
= T² = r³
Therefore, the second option,T^2=r^3 which is equivalent to T² = r³ is the correct option
2. Which of the following are effects of melting sea ice? Select the two correct answers.
The melting of sea ice causes a lot of changes in the climate of an environment.
The presence of sea ice in oceans, reduces the surface area thereby causing a minimal reflection of sunlight but once sea ice melts, the surface area of the water is increased and this would results in a reflection of sunlight.
The sea ice absorbs less thermal energy or radiation from the sun(solar energy) and keeps the surface cooler but once the sea ice is melts, the resulting water, absorbs a lot of thermal energy or radiation from the sun, causing the surface of the water to be hot.
Therefore, the options "The exposed water reflects back more sunlight than did the ice" and
"The exposed water absorbs more thermal energy from the sun than did the ice" are the correct options.
3. A group of scientists are studying observable matter in a cluster of galaxies. They conclude that the cluster has only a small percentage of the mass required to keep it from flying apart. Why does the cluster remain intact?
It has been observed that galaxies present in the solar system have an attraction for one another such that they are drawn to each by force of gravity that is present in the solar system. And because of these, galaxies form clusters in the solar system.
Dark matter is a large amount of matter that is present in the solar system. Dark matter is the reason by which galaxies can form and maintain the clusters that they form around each other because it provides them with the force of gravity and sufficient mass that the galaxies require to prevent them from separating or flying away(apart) from one another
Therefore, the option "Dark matter provides the mass and gravity needed to keep the cluster together" is correct.
The simplified version of Kepler’s third law in a situation when one of the planets is compared to Earth will be T³ = T².
The effects of melting sea ice include:
The exposed water reflects back more sunlight than did the ice.The exposed water absorbs more thermal energy from the sun than did the ice.A cluster will remain intact because the dark matter provides the mass and gravity needed to keep the cluster together.
It should be noted that Kepler's third law of planetary motion simply represents the ratio of the square of the orbital period of a planet is to the radius of orbit of other planets. This can be expressed mathematically as T³ = T².
