Answer:
im pretty sure it's the second option (external fertilization) and the last option (external development) because it said that they put sperm and eggs into the environment which therefore creates fertilized embryos that are free swimming and become part of the zooplankton. they are never being carried by the starfish so therefore it's all external. so external fertilization and external development.

A relationship in which one organism benefits while the other is neither harmed nor helped is called commensalism.
What do you mean by Organism?An Organism may be defined as a living thing made up of one or more cells and able to carry on the activities of life.
Commensalism is an interaction between the organisms of two different species where one is benefitted in the presence of another, while the other neither harmed nor benefitted.
Therefore, a relationship in which one organism benefits while the other is neither harmed nor helped is called commensalism.

In her notes, Celeste wrote that the human body systems consist of molecules, cells, tissues, organs, and organ systems. What problem will Celeste have on her body systems test when she studies this information? A. She forgot to list organism as a level. B.She should have written chemicals/molecules. C.This is not the correct sequence. D.These are not body systems.
Answers
Answer:
The correct answer is - option A.
Explanation:
Celeste wrote only six levels of organization in her notes that include molecules, cells, tissue, organ, and organ system. That is the correct sequence from smaller to larger but she forgot the sixth and a higher level of the body system of the organization.
This level is the organism which includes the organ system. Organ system comprises various organ those perform different action to perform a larger level function.

In radishes, the gene that controls color exhibits incomplete dominance. Pure-breeding red radishes crossed with pure-breeding white radishes make purple radishes. What are the genotypic and phenotypic ratios when you cross a purple radish with a white radish?
Answers
Answer:
Genotype Ratio = 1 RW: 1 WW
Phenotype = 1 Purple: 1 White
Explanation:
The gene for the color of radishes exhibits incomplete dominance and the heterozygous genotype gives purple color to radishes. The genotype of the heterozygous parent plant with purple radishes would be "RW." A cross between a purple radish (RW) and a white radish (WW) would give progeny in the following ratio.
The genotypic and phenotypic ratios at the time when you cross a purple radish with a white radish should be 1 RW: 1 WW and 1 Purple: 1 White.
Genotypic and phenotypic ratios:here the gene with respect to the radishes color represent the incompletion of the dominance and also contains the heterozygous genotype that provides the purple color that convert into the radishes.
So here we can conclude that The genotypic and phenotypic ratios at the time when you cross a purple radish with a white radish should be 1 RW: 1 WW and 1 Purple: 1 White.

What is the inherited variation?
please hurry
Answers
Answer:
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
The size of the lizards' legs is the inherited variation in this situation. It is likely that hereditary variables, which can be transferred from parents to children, are responsible for the variance in leg size.
What is an inherited variation?Genetic changes that are transferred from parents to children are referred to as inherited variation. Every person has a distinct set of genes that influence a variety of qualities, including physical attributes, behaviour, and disease risk. These genes, which a person inherits from both parents, are prone to chance mutations that happen throughout DNA replication and recombination.
In the aforementioned illustration, this genetic variation in leg length resulted in differential availability of food, with longer-legged lizards having better access to food sources. Because they had a harder time getting to food and might have been less fit, lizards with shorter limbs gradually decreased in population.
Therefore, the size of the lizards' legs is the inherited variation in this situation. It is likely that hereditary variables, which can be transferred from parents to children, are responsible for the variance in leg size.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answers
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.
Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different. Which of the groups made a statement about mitosis and meiosis that is most correct?
A). Group 1, they said that mitosis is involved in the growth and repair of cells and undergoes cell division twice, while meiosis is involved in sexual reproduction and undergoes cell division once.
B). Group 2, they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in sexual reproduction and undergoes cell division twice.
C). Group 3, they said that mitosis is involved in sexual reproduction and undergoes cell division twice, while meiosis is involved in the growth and repair of cells and undergoes cell division once.
D). Group 4, they said that mitosis is involved in sexual reproduction and undergoes cell division once, while meiosis is involved in the growth and repair of cells and undergoes cell division twice.

Answer:
B)
Explanation:
Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.
Mitosis- growth and repair one cell division 2 genetically identical diploid cells
Meiosis- produce gametes, two cell division, 4 genetically different haploid cells
Hope this helps :)
The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.
What is cell division?Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.
Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.
Thus, the correct option is B.

Which of four factors that affect evolution apply to the finches that the Grants studied?
Answers
Answer:
The Grants have focused their research on the medium ground finch, Geospiza fortis, on the small island of Daphne Major. Daphne Major serves as an ideal site for research because the finches have few predators or competitors. (The only other finch on the island is the cactus finch.) The major factor influencing survival of the medium ground finch is the weather, and thus the availability of food. The medium ground finch has a stubby beak and eats mostly seeds. Medium ground finches are variable in size and shape, which makes them a good subject for a study of evolution.
