Can someone please give a small description on these words based off of animals cell
Golgi body
Cell membrane
Centrosome
Nucleus
Vacuole
Mitochondrion
Answer:
1.A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
2.The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
3.The cytocenter or centrosome is a cellular organelle that is not surrounded by a membrane; ... " centrosome- related bodies " (CRBs for centrosome- related bodies) are often seen at ectopic sites.
4.The nucleus is a membrane-bound organelle that contains genetic material (DNA) of eukaryotic organisms. As such, it serves to maintain the integrity of the cell by facilitating transcription and replication processes. It's the largest organelle inside the cell taking up about a tenth of the entire cell volume.
5.A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products.

Radiant energy is converted into chemical energy, and this is a light-independent stage.
Sugar molecules like glucose are formed, and this is a light-dependent stage
The final products of fotosynthesis are carbohydrates, ATP, NADPH, and oxygen is released. During the firt stage of photosynthesis, radiant energy is converted into chemical energy, and this is a light-dependent stage.
Stages of Photosynthesis
Photosynthesis involves two stages: light-dependent and light-independent reactions.
During light-dependent reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.Light-independent reaction is known as the Calvin cycle, and it takes place in the stroma. Sugars or carbohydrates are synthesizedLight-Dependent reaction
Chlorophyll molecule in Photosystem II captures luminous energy from the sun. The pigments absorb light, exciting the electrons, which get in a higher energy level. Excited electrons leave photosystem II and move to photosystem I along the electron transport chain. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. Photosystem I absorbs more luminous energy that drives the electrons to another electron acceptor, from where they get transported again and used to produce NADPH molecules. When electrons are sent from Photosystem I, they are replaced by new electrons coming from photosystem II through the transport chain. As electrons go through the transport chain, their released energy is used to produce ATP molecules.

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.

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.
