Answer:

By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

Explanation:

Fertilization is the union of a male and a female gamete that gives rise to a zygote that is the first cell of the organism. Fertilization occurs in the sexually reproducing organisms. After fertilization , the zygote undergoes continuous division and Gives rise to a mass of cell that later on differentiate into cells that assume specialized function, each group of specialized cell then gives rise to organ system of the organism.

Answer:

A. RNA polymerase is always present in a cell, but sometimes present in viruses.

B. tRNA is always present in a cell, but Never present in viruses

C. Ribosomes are always present in a cell, but Never present in viruses.

D. Genes are always present in a cell, but always present in viruses..

Explanation:

A. RNA polymerase is always present in a cell, but sometimes present in viruses. RNA polymerase is the enzyme responsible for transcription in eukaryotic cells, it is the enzyme that stimulates transcription, that is, the passage from DNA to RNA. All RNA viruses encode in their genome an RNA-dependent RNA-polymerase (RdRp) that acts as a catalytic subunit, along with other viral and cellular proteins, in the replication of the viral genome. B. tRNA is always present in a cell, but Never present in viruses Transfer RNA is a type of ribonucleic acid that is responsible for transporting amino acids to ribosomes where, according to the sequence specified in a messenger RNA (transcribed, in turn , from DNA), proteins are synthesized. C. Ribosomes are always present in a cell, but Never present in viruses. Ribosomes are responsible for the granular appearance of the cytoplasm of cells. It is the most abundant organelle, several million per cell. Viruses do not have cytoplasm or ribosomes (elements necessary to form a cell), so they cannot multiply on their own and they need to infect the cell of another organism to do so.D. Genes are always present in a cell, but always present in viruses.Genes are the storage units of genetic information, they are fragments / segments of DNA that encode a specific functional product. Viruses are small pieces of RNA (ribonucleic acid) or DNA (deoxyribonucleic acid), many are encapsulated in an envelope made of base of proteins known as capsid, others protect their genetic material with a membrane or envelope derived from the cell they infect and some others also surround their capsid with a cell membrane. RNA viruses bring with them their own genetic information copying machines (eg, RNA polymerase enzyme) or possess genes (genetic information) that produce the proteins required to assemble the copying machines within the cell that they infect, thereby which makes them independent of the cellular machinery and capable of infecting cells that are not actively reproducing.

Answer:

Answer is below.

Explanation:

The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years to millions of years.

Answer:

The plants producing more bubbles indicates that photosynthesis is more effectively driven by BLUE AND RED LIGHTS.

Please find explanation below.

Explanation:

According to this question, an experiment is being carried out to determine which color of light is most effective at driving photosynthesis. Three sets of aquatic plants (plants A, B and C) are used for this experiment. Plant A was placed under blue light, plant B under red light, and plant C under green light.

Photosynthesis is the process whereby plants manufacture their food (glucose) using sunlight energy. However, it is worthy to note that OXYGEN GAS is one of by-products of this metabolic process. Hence, as stated in this question, the bubbles noticed to be coming off the leaves is OXYGEN gas.

However, more products in a reaction denotes the fast rate of such reaction. Plants A and B produced more bubbles than plant C. This means that photosynthesis in plants A and B, which released more OXYGEN GAS as BUBBLES, is more effective under the blue and red light respectively.

Answer:

A. The virus depends entirely on a host cell to reproduce

Viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.

The main difference between single- celled and multicellular organism is that single- cellled organisms are made up only single cell on the other hand multicellular organisms are made up of multiple cells.

Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.

Prokaryotic Cell

Prokaryotic cells are single-celled microorganisms known to be  earliest on earth.

Eukaryotic cell

Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.

Difference between unicellular and multicellular.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level.

Unicellular organism has simple body organization and multicellular organism have complex body organism.

Therefore,viral reproduction different from the reproduction of single-celled and multicellular organisms because the virus depends entirely on a host cell to reproduce. Thus, option A is correct.

Explanation:

It is false that the nucleus takes up about 30% of the cell’s volume.

The part of a cell that houses the chromosomes in biology is nucleus. The membrane-enclosed nucleus is where RNA is synthesized from the chromosomal DNA. Enlarge. component cells.

The nucleus' principal jobs include storing the cell's DNA, preserving its integrity, and assisting with transcription and replication.

One of the most noticeable features of a eukaryotic cell is its spherical nucleus, which normally makes up 10% of the cell's volume.

The genetic information and other instructions necessary for cellular functions are found in the double-membraned organelle known as the nucleus. It is one of the biggest organelles and is only present in eukaryotic cells.

Thus, the given statement is false.
