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.

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.

4- Las plantas que viven en sitios húmedos y con poco sol tienen raíces poco profundas. Las que viven en sitios de mucho calor tienen raíces muy profundas. ¿Por qué?
Esto es debido a que en los lugares húmedos las plantas absorven el agua con las hojas y no necesitan hacer crecer la raíz para buscar agua. En cambio, las plantas que viven en lugares calurosos necesitan agua por lo que expanden las raíces hacia abajo para poder encontrar líquido e hidratarse.

Answer:
We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.
Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Answer:
Deforestation on rainforests and other natural environments can have a devastating effect on the whole world. First, it leads to the loss of many animal and plant species, decreasing the biodiversity that our planet enjoys. It can also lead to the degradation of soil and to erosion, as trees and plants usually hold the ground in place and provide necessary nutrients to it. Deforestation also has a negative effect on climate change, as trees are able to absorbe an enormous amount of greenhouse gas emissions. Without them, the greenhouse effect is amplified, worsening climate change.

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

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.
The two types of prokaryotic organisms are Bacteria and Archaea.
This corresponds with what is given in the group 1 as seen in the attachment that came with the question.

Describe the sequence of events during a blood clot.
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.
Platelet plug. ...

The chart shows information about three different embryos early in their development.
Which is best supported by the information in the chart?
Species X and Y are not related to humans.
Species Y and Z are not related to humans.
Species X and Z are related to humans.
Species X and Y are related to humans.
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
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.

Why can the geologic time scale change?
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale. The overall duration and relative length of these large geologic intervals is unlikely to change much, but the precise numbers may "wiggle" a bit as a result of new data.

B. it's surface area remains constant
C. the surface area decreases
D. it's surface area increases more rapidly than it's volume increases
Answer:
D
Explanation:
Larger organism increases more in volume than area. That's why larger organism uses respiratory systems or organs and systems instead of simple diffusion for removal of waste and absorption of nutrients.
