What are the sub-phases of interphase and what occurs in each phase?
Answer:
Phases: G1, S phase and G2
Functions:
- G1: cell grows
- S phase: DNA replication
- G1: organelle replication and increase of the cytoplasmatic proteins
Explanation:
Interphase is the phase of the cell cycle in which the cell prepares for its division and ensures that each daughter cell has the correct required materials for cell survival (i.e., a correct amount of DNA, organelles, proteins, etc). Interphase can be divided into three subphases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2). During G1 phase, the cell increases its size and replicates its organelles as necessary. During S phase, the cell growth continues, the DNA of the cell is replicated and rapidly assembled into chromatin. During G2 phase, the cell increases its cytoplasmatic content producing molecules it still needs to divide (e.g., essential M-cyclin molecules) and replicates its organelles (e.g., mitochondria in animals and chloroplasts in plants).

which food groups tend to have the highest nutrient density ? Which food groups have the lowest nutrient density ? What factors contribute to Foods having high or low nutrient density ?
Answer:
I think vegetables, fruits and dairy are the highest nutrient density, candy and different types of unhealthy food have the lowest nutrient density. It contributes to the amount of calories.
Explanation:
Remember that highest nutrient density is low calories and the lowest nutrient density is a lot of calories. There is probably no explanation about this.

What causes matter to be in a particular state (phase)?
Answer:
In the physical sciences, a phase is a region of space (a thermodynamic system), throughout which all physical properties of a material are essentially uniform. Examples of physical properties include density, index of refraction, magnetization and chemical composition. A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is another separate phase. (See state of matter § Glass)

Examine the photographs of 16 species of anole lizards and sort them into as many groups as you want according to how they appear in the photographs. Explain how you grouped the lizards and your rationale for the various groupings. If you picked a body feature, speculate about the advantages or disadvantages of such a body feature in the environment that species occupies.
Answer:
On the basis of physical appearance.
Explanation:
We grouped the lizards into various groups on the basis of similarities and differences in the body structure, appearance and colour etc. The legs of anole lizards are small legs with pads on their feet for gripping surfaces which give them the advantage to climb up the trees while on the other hand, these small legs can't help in the survival on the land because they can't run too fast from their predators with these short legs so these legs has benefit in climbing the tree but disadvantage in running on the land.

Bones grow in diameter due to bone formation
Answer:
Osteoblasts move in and ossify the matrix to form bone. Even though bones stop growing in length in early adulthood, they can continue to increase in thickness or diameter throughout life. The increase in diameter is called appositional growth.

Explanation:
Which is not a cost for organisms that sexually reproduce?
Answer:
Identical shape and structure.
Explanation:
Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.

Reproducción sexual
La reproducción sexual consisten en la ___________ de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los ___________ son células especializadas que se forman por un proceso __________ y tiene en su núcleo la mitad de la información __________ de un organismo, por lo que reciben el nombre de células ___________ de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la ___________ genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son ___________ a ellos. El proceso en el que se une las células sexuales se le conoce como ___________. En los animales esta pude ser interna o externa.
Answer:
La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.
Explanation:
Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).
Which of the following best describes the difference between population size and population density?
A. Population density measures the abundance of an organism, whereas population size measures the distribution
B. Population size measures the abundance of an organism, whereas population density measures the distribution
C. Population size measures abundance, but population density measures how rapidly the size changes
D. Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population
E. None of these descriptions are correct
Population size refers to the number of individuals, while population dendity refers to the number of individuals per unit of area or volume. The correct option is E. None of these descriptions are correct.
------------------------------------------------
Before answering the question, let us review the concepts of population size and density.
Population size refers to the number of individuals composing a population.Population size might determine the destiny of the population.
A small population has more chances to get extinct than a bigger-sized population.
Density refers to the average number of individuals of the same species per unit of area or volume. This measure may be more significant than population size.
To estimate population density there are two possible methods: Direct methods and indirect methods.
Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes.
According to these concepts, the correct option is E. None of these descriptions are correct.
