Answer:

Scientists began to mark division on the geologic time scale when patterns and similarities started emerging from archeological studies. Patterns such as the discovery of fossils that were formed within the same period.

Explanation:

Geologists who study matter that make up the Earth's crust (whether solid gaseous or liquid), as well as matter from other terrestrial planets and the processes that influence the formation and condition of this matter, are called geologists.

They have successfully calibrated history into various phases of time intervals. These intervals are event-based intervals. For example, you have Eons, Eras, and Periods.

An Eon is a billion years. An example is the Neoproterozoid Eon. Eons are made up of several Eras and Eras are made up of periods. An example of an era is the Mesozoic era. Whilst periods are smaller units of an era, eg. Triassic era.

As scientists deduced the causes for the formation of fossils and topographical remains/patterns, they collected events that occurred within the same time period and group them together.

This range of events became known as the geological time scale.

The age of fossils and rocks is also used to map out the calibrations on the scale.

The age of fossils and rocks is determined using the process of radioactive dating.

Explanation:

Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

Environment is defined as a compilation of all the factors living and nonliving and the outcomes they have on human life. Due to their ties to the forest, its plants, wildlife, water, and air. The air is filtered and hazardous gases are absorbed by the forest and trees. Plants filter water, lessen the likelihood of flooding, preserve the natural equilibrium, and do many other things.

Viruses are more like robots than actual living things, even though they do replicate and adapt to their surroundings. The viruses are thought to be dead in their natural habitat since they lack any cell-like properties. However, inside the host cell, the viruses employ the host's technological infrastructure to carry out all necessary tasks including reproduction.

Thus, viruses are not comprised of cells, they cannot maintain a stable internal environment, they cannot reproduce, and they cannot produce their own energy.

protista

Explanation:

it exists in haploid cells reproduced by binary fission

Goa's climate is tropical, hot all year round, with a long and sunny season, which runs roughly from mid-October to mid-May, and a rainy season due to the south-west monsoon, more or less from late May to early or mid-October, and characterized by stuffy weather, cloud cover and frequent rains, which occur almost daily .

The coconut seed is especially well adapted to increasing its range by the method of ocean dispersal. The seed floats when its outer layers dry out. The buoyant coconuts drift on ocean currents and end up on tropical beaches where they germinate and take root.

Coconut tree grows only in the tropical climate. This plant live on the sandy soil, requires a lot of sunlight and regular rainfalls. Coconut tree does not tolerate low temperatures and low percent of humidity.

so goa is one place which is suitable for growing coconut.

Explanation:

Answer: The cell membrane is made up of phospholipids and the overall name is the Phospholipid bi-layer

Explanation:

The cell membrane has two rows of phospholipids.  A phospholipid is broken into two parts, the heads and tails.  The heads are hydrophilic (water-loving) and point to the outside and inside regions making the inner and outer wall, while the tails are hydrophobic (water-hating) and face each other to make the inside of the membrane.  There are also molecules of cholesterol and proteins throughout the membrane.

Phospholipids are the building blocks of a cell membrane. A single phospholipid molecule consists of two ends: the head and the tail.

Phospholipids are amphiphilic molecules with both hydrophobic and hydrophilic fatty acid chains.

They are found in all living organisms as the primary components of cell membranes. Nature contains a variety of phospholipid classes with varying polar moieties.

Phospholipids are glycerol esters, fatty acid esters, phosphoric acid esters, and other alcohol esters.

Phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylserine are the most common phospholipids.

The phospholipid bilayer, which forms a stable barrier between two aqueous compartments, is the membrane's fundamental structure.

These compartments are the inside and outside of the cell in the case of the plasma membrane.

Thus, this is the basic structure of the cell membrane with regard to specific molecules.

Answer:

C

Explanation:

Phototaxis (phototactic response) is the cellular behavior in which cells swim toward or away from the light source. The euglena have eyespots that detect light so that it can move toward sunlight for photosynthesis.

Euglena require an eyespot  to exhibit phototactic behavior. Thus option C is correct.

Phototaxis is defined as the movement of an organism in response to external stimulus  that means light, it is a locomotory movement of living organisms towards the source of light or away from the source of light.

Taxis means the  movement of an organism in response to a stimulus like light or  food, it is an innate response of an organism to variation in light intensity and direction.

More is the intensity of light in a particular direction the more will be phototactic stimulation occurs in the organism, its own biological reason and phototactic response are incidental and serve no end purpose.

The advantages of phototaxis are the regulation photosynthesis, the finding of food in phototrophic organisms, facilitation of larval dispersal, or the increased likelihood of gamete fusion on the surface.

Thus option C is correct.

Explanation:

Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.

Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.

An element is define as a type of substance that is impossible to  break into smaller pieces by the help of chemical process. There are several rules that should be followed at the time of assinging name of the elements. The first rule is name of the element is not a proper noun. The second rule is the symbols of the element that must be of one or more than one symbol.

Density is define as the mass per unit volume it means that 1 kg mass present in 1 meter cube is called density, density is also states that the how compact an material.

Mathematically

Density = mass/volume

S.I unit of density is kg/m^3

Density is higher in solid as compare to liquid and density of liquid is higher than gas so density is in order of SOLID>LIQUID>GAS. So we know that solid is compact in nature as compare to liquid and gas.

Answer:

for a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. ... Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud.

Explanation:

For a fossil to be formed, it is required for a plant or an animal to be covered by the sediment. Thus, the correct option is D.

Fossils are the preserved evidence of the organisms which were present on this planet once. There are four types of process which contribute to the formation of a fossil. These are mineralization, carbonization, encrustation and distillation. These processes occur once a living organism has become trapped within the surrounding sediment, and it is primarily depend upon the mineral composition of silt and water available.

Fossil formation begins when a living organism or any part of an organism falls into the soft sediment, such as mud. The organism or part of it then gets quickly buried by more sediment. As more and more sediment collects on top of the organism, the layer with the organism or part becomes compacted and it undergoes deep into the Earth.

Therefore, the correct option is D.

Answer:

A phosphate backbone is the portion of the DNA double helix that provides structural support to the molecule. DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
