Answer:
Answer is 512 nucleosomes.
Explanation:
DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.
What are nucleosomes?Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.
Given,
Genome size = 92,672 base pairs
Linker DNA = 35 bp
The total number of base pairs = number of base pairs in nucleosome core + linker DNA
= 146 + 35
= 181
The number of nucleosomes can be calculated as:
Nucleosomes = Genome size ÷ total number of base pair
= 92,672 ÷ 181
= 512
Therefore, there are 512 nucleosomes are present in the Drosophila.

explain the importance of meiosis in the life cycle and evolution of the water mold?
Answer:
The diploid form of the mold is called the zygospore, which is were meiosis occurs. Some protists life cycles switch between diploid and haploid phases. This is known as alteration of generations. The water mold reproduces asexually by producing spores, which are diploid. The water mold reproduces sexually by producing gametes which are haploid.
Explanation:
Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

qual é o resultado da meiose ?
Answer:
El proceso da como resultado cuatro células hijas que son haploides, lo que significa que contienen la mitad del número de cromosomas de la célula madre diploide. La meiosis tiene similitudes y diferencias con la mitosis, que es un proceso de división celular en el que una célula madre produce dos células hijas idénticas. Espanol
English: The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

Answer:
C
Explanation:
Suppose you remove the rabbits, grasshoppers, birds, and mice ( the herbivores) from a food web that also includes grass, mushrooms, lizards, and hawks. Which organisms would be affected and how?
If you remove the herbivores from a food web that also includes grass, mushrooms, lizards, and hawks, the organisms that would be affect are lizards, and hawks.
A food web shows all the possible feeding relationships in an ecosystem. Recall that there is an interconnection between organisms which involves exchange of matter and energy through feeding relationships.
In the food web, the grass is the producer, the herbivores are the primary consumers and the carnivores are the secondary consumers. These secondary consumers eat the primary consumers.
Lizards eat grasshoppers and hawks eat birds. When these are removed from the food web, the Lizard and Hawk are most affected because they will starve owing to lack of prey.

on an island there are three mice populations. Population 2 cannot contact populations 1 and 3. What name is given to this situation?
Answer:
Isolation
Explanation:
On a island, there are three mice population in which one population cannot contact other populations. This situation is an example of allopatric speciation.
What is Allopatric speciation?Allopatric speciation is also referred to as geographic speciation. It is also called vicariant speciation. Allopatric speciation is a mode of speciation which occurs when the biological populations become geographically isolated from each other to an extent that it prevents or interferes with the normal gene flow in a population.
There are several factors which are required for the allopatric speciation to take place such as isolation of a population, time, and natural selection in an environment. Earthquakes, floods, and migration all are the ways through which a group of individuals of the same species can become isolated.

What is happening to the growth of a population in which death rate equals birthrate, but emigration is greater than immigration?
Answer:
Explanation:
A negative growth rate means it is decreasing. The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area. i mean
The growth of the population is decreasing.
Growth rate of the population depends upon:--Birth rate
-Death rate
-Immigration
-Emigration

What role do the macromolecules starch and simple sugars play in fruit storage and ripening?
The role that is played by macromolecules such as starch and simple sugars in fruit storage and ripening is that the unripe bananas store starch in their chlorophyll.
Macromolecules refer to very large molecules. The four main classes of macromolecules include lipids, proteins, nucleic acid, and carbohydrates.
It should be noted that starch is stored in the chlorophyll content of the peel of the unripe bananas. During ripening, there'll be an increase in the breakdown of the starch that can be found in the fruit and this will ensure there's an increase in the glucose too.

the red blood cells and brain are two body tissues that derive most of their energy from
[tex] \huge \mathfrak{{ \pmb{ \underline{ \red{Answer}}}}}[/tex]
The red blood cells and brain are two body tissues that derive most of their energy from glucose.
Glucose is the answer.
The red blood cells and brain are two body tissues that derive most of their energy from carbohydrates. The correct option is C.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
Under normal conditions, glucose serves as the brain's main energy source.
Using either glycolysis or oxidative phosphorylation—the latter of which is 15 times more efficient—glucose is used to create energy in the form of adenosine triphosphate (ATP).
In the absence of glucose, the brain has backup energy sources, such as ketones created by fatty acid metabolism, which predominantly takes place in the liver.
These include 3-hydroxybutyrate, acetone, and acetoacetate (3BHM).
Thus, the correct option is C.
