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.

Question: "The energy that organisms use for supporting life processes such as movement and reproduction are released into the ecosystem as what type of energy?"
Answer: "Heat energy is used by organisms for supporting life processes, including movement and reproduction. Hence, Option B is the correct choice."
Heat energy is the degree of internal energy contained in an organism and is released into the ecosystem.
What is heat energy?Heat energy is what generates the internal and random movement of the particles of a body.
Characteristics of heat energyOrganisms constantly release heat energy.This energy is renewed through the consumption of food, which contains the calories that allow us to continue emitting that energy as long as we live.Therefore, we can conclude that the temperature of an organism and its ability to generate life processes such as movement depend on its heat energy.

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.

Explanation: used quizziz
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."

Describe what might happen to an amino group or a carboxyl group of an amino acid, if that amino acid is placed into water.
Answer:
Amino acids are the monomers that makeup proteins. This amino acid is unionized, but if it were placed in water at pH 7, its amino group would pick up another hydrogen and a positive charge, and the hydroxyl in its carboxyl group would lose and hydrogen and gain a negative charge.
Explanation:
Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. In the aqueous environment of the cell, both the amino group and the carboxyl group are ionized under physiological conditions, and so have the structures -NH3+ and -COO–, respectively. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. This R group, or side chain, gives each amino acid protein-specific characteristics, including size, polarity, and pH.

TRY IT Distinguish Elements Explain why there are more substances on Earth than are listed on the periodic table of elements.
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.

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.
