Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth's continents were once part of an enormous, single landmass called Pangaea.

Answer:

Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

Of the options listed, "They are prokaryotic" and "They are not multicellular" are characteristics that both blue-green algae and bacteria share.

Blue-green algae, also known as cyanobacteria, are a type of bacteria that are capable of performing photosynthesis. This makes them unique among bacteria, as most other bacteria do not have the ability to produce their own food in this way. As a result, blue-green algae play an important role in the carbon cycle and contribute to the production of oxygen in the Earth's atmosphere.

Blue-green algae can be found in a variety of environments, including fresh and salt water, soil, and rocks. Some species are free-floating, while others form colonies or filaments. In certain conditions, such as nutrient-rich water or high temperatures, blue-green algae can grow rapidly and form blooms, which can have negative impacts on aquatic ecosystems and human health.

Despite their classification as bacteria, blue-green algae have a number of characteristics that are more similar to algae than to other bacteria, which is why they are sometimes referred to as "blue-green algae."

A)Ocean floor evidence of sea floor spreading.

Explanation:

evidence pointing to the steps or process  of seafloor spreading and effective plate motion This theory was accepted by many scientist because  it depended  on hard evidence and could describe most of the modern geological structures such as ocean basins,

What is the tectonic theory?

The theory of plate tectonics plates  says  that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.

What is a tectonic plate?

They are huge slabs of rock that cover the earths mantle When a earthquake occurs that's because the tectonic plate is breaking  that makes the ground shake  During the earthquake and afterward, the plates keep on shaking until they are stuck again!

The plate tectonic theory gave the concept of land and sea formation. "Ocean floor evidence of seafloor spreading" acted as evidence to support the plate theory. Thus, option A is correct.

The plate tectonic theory states about the formation of the lithosphere by the movement of the plate tectonics located deep in the mantle and core layer of the earth. These plates show movement slides over each other to produce lands and drifts to form the oceans.

At a very early there was a supercontinent, Pangaea that slowly shows the formation of the current continent by the movement of the tectonic plates. These solid hard rocks of the earth layers allowed the formation of the various land formations.

The seafloor spreading is the best evidence that supports the tectonic plate theory that described the formation of the oceanic structures including the trenches and basins. The geological structures of the ocean floors supported the theory.

Therefore, option A. evidence of seafloor spreading supported the plate tectonic theory.

Answer:

The periodic table of elements includes only elements.

Explanation:

All the materials on Earth are made up of the same elements, which can be found on the periodic table. These elements combine to form compounds, or mixtures such as water, a compound of hydrogen and oxygen, or air, which is a mixture of nitrogen, oxygen, carbon dioxide (a compound!) and many other gases, even water vapor. It is the combination of these elements in different ways that gives us so many different substances. Hope this helps!

Answer:

Explanation:

Elements are pure substances with only one type of atom.

The substances on Earth are created when two or more elements are combined.

Because elements can combine to form compounds, more substances can be created on Earth.

The cell cycle aids in the conservation of genetic properties by the first stage which replicates DNA from the cell or Anaphase.

Cell cycle aid the conservation of genetic information through the use of either a positive feedback mechanism or a negative feedback mechanism.

A cell cycle can be defined as an ordered sequence of events that takes place within a living cell as it grows and divide into two (2) daughter cells.

Basically, a cell cycle is made up of four (4) distinct stages and these include:

A genetic information refers to the heritable biological information that are typically stored in the base sequence of an organism's deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) in certain viruses, according to their genetic code.

Generally, living cells communicate with one another by generating, transmitting, receiving and responding to chemical signals within the body of a living organism.

On a related note, cell communication is not completely perfect and as such causes genetic variation.

However, cell cycle aid the conservation of genetic information through the use of either a positive feedback mechanism or a negative feedback mechanism.

Hence, living organisms are able to transfer their genetic information from one generation to another based on the actions of cell cycle.

Answer:

If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.

Explanation:

Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.

The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.

When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:

When one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.

Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.

Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.

Explanation:

Different strains appear every year, so the vaccine changes.

Influenza of flu is the viral infection for which a person should be vaccinated every autumn and winter. This is because the virus has been identified to have different strains.

Viruses are the unicellular organisms with genetic material either DNA or RNA which is surrounded by a protein coat. Many of the viruses are found to be pathogenic for humans.

Influenza virus is one of them. Influenza (flu) vaccines (also called as “flu shots”) are vaccines that protect against the influenza virus strains that are most common during the season. Generally, most of the flu vaccines are “flu shots” which are given with a needle in the arm, however there is a nasal spray flu vaccine as well.

Influenza (flu) is a contagious respiratory illness caused by influenza virus that infect the respiratory tract. People who are immunologically compromised or are in certain health condition are found to be more vulnerable to this virus.
