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.
What is plate tectonic theory?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.

How did Wegener think that continents went together?
Explanation:
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.

What type of asexual reproduction is shown in the image below?
A)Binary Fission
B)Spores
C)Budding
D)Vegetative reproduction
It's budding or vegetative productioon it's one of them i think tell me if i am wrong
The type of asexual reproduction shown in the image below is Option C) Budding.
Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. For example, the small bulb-like projection coming out from the yeast cell is known as a bud. Since the reproduction is asexual, the newly created organism is a clone and excepting mutations is genetically identical to the parent organism. Organisms such as hydra use regenerative cells for reproduction in the process of budding.
In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.Internal budding or endodyogeny is a process of asexual reproduction, favored by parasites such as Toxoplasma gondii. It involves an unusual process in which two daughter cells are produced inside a mother cell, which is then consumed by the offspring before their separationBudding, in biology, a form of asexual reproduction in which a new individual develops from some generative anatomical point of the parent organism. In some species, buds may be produced from almost any point of the body, but in many cases budding is restricted to specialized areas. The initial protuberance of proliferating cytoplasm or cells, the bud, eventually develops into an organism duplicating the parent. The new individual may separate to exist independently, or the buds may remain attached, forming aggregates or colonies. Budding is characteristic of a few unicellular organisms (e.g., certain bacteria, yeasts, and protozoans). However, a number of metazoan animals (e.g., certain cnidarian species) regularly reproduce by budding.Learn more about Budding

In order to measure the absorption spectrum of CoCl2, you need to dilute the stock solution to 0.32 M. What volume of the stock solution (0.8 M concentration) and water should be mixed to make a 10 mL solution of 0.32 M?
Explanation:
Volume of stock solution needed
= 10mL * (0.32M/0.8M)
= 10mL * (4/10) = 4mL.
Volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
The volume of water needed in this case will be equal to 6 ml.
What is the stock solution?To make a stock solution, weigh out the proper amount of a pure solid or measure out the proper amount of a pure liquid, put it in the right flask, and then dilute it to the desired volume. Depending on the intended concentration unit, many methods can be used to measure the reagent.
For instance, to make a solution with specified molarity, you weigh out the proper mass of the reagent, mix it with some solvent, and then add enough liquid to make the necessary volume. You measure out the right amount of solute and add enough solvent to get the right total volume to create a solution where the solute concentration is expressed as a volume percent.
A highly concentrated stock solution is frequently diluted to create solutions. The stock solution is moved to a new vessel and produced to a new volume at a known volume.
Here,
The volume of stock solution needed
= 10mL × (0.32M/0.8M)
= 10mL × (4/10) = 4mL.
The volume of water needed
= 10mL - Volume of stock solution
= 10mL - 4mL = 6mL.
Therefore the volume of water needed here is equal to 6 ml.

how does the cell cycle aid the conservation of genetic information
Explanation:
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:
Gap 1 (G1).Synthesis (S).Gap 2 (G2).Mitosis (M).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.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:
Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.
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:
Dominant RecessiveWhen 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.

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