Answer:
Adversely affected.
Explanation:
Dam adversely affected the organisms living in the estuary because dam controls the flow of water of estuary. Dams divide rivers that formed upstream and downstream habitats. The migratory fish depends on the natural environment and flow of river. Due to dams, change occur in rivers flow, the water temperature and natural conditions. This change prevents migratory fish from mating and/or hinders the development of fish larval.
if you know you have 32% adenine you can figure out the percent of cytosine?
please hurry
Answer: 18%
Explanation:
Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio
32% Adenine = 32% Thymine
32 + 32 = 64 100 - 64 = 36 36/2 = 18
18% of Cytosine and 18% of Guanine

During experiment yeast fermentation ，how is the anerobic condition maintained to ensure that the fermentation process is completed？
Answer:
By covering the solution.
Explanation:
The anaerobic condition is maintained to ensure that the fermentation process is completed by covering the solution so that no oxygen enters the solution. Anaerobic conditions are necessary for the fermentation process because the anaerobic conditions allow the production of lactic acid, ethanol and carbondioxide gas from pyruvate. Without anaerobic condition, the fermentation process does not occur so that's why we can say that anaerobic conditions should be maintained for the fermentation process.

which of the following would astronomers most likely measure in light-years distance between stars distance between the earth and the moon?
Answer:
Astronomical unit usually refers to that unit which represents the mean distance starting from the center of the earth to the center of the sun. The distance from the sun to all the planets and other astronomical bodies are represented in the astronomical unit. It is denoted by AU. This unit is mainly used by the Planetary scientists and the Astronomers, as it is helpful in understanding the relative distance between two objects in the solar system.
Explanation:
Answer:
distance between stars
Explanation:
The distance between the Earth and the stars is enormous. As a result, larger units like light-years are useful for expressing these distances. When a star is eight light-years away from the Earth, the light from that star takes eight years to reach us. To put it another way, the light that we see today originated from that star eight years ago.
The astronomical unit usually refers to the unit that indicates the average distance between the earth's center and the sun's center. The astronomical unit represents the distance between the sun and all of the planets and other celestial bodies. AU is the abbreviation for it. Planetary scientists and astronomers mostly utilize this unit because it aids in determining the relative distance between two objects in the solar system.

1. Elaborar resumen del texto sobre los estados de la materia( usar alguna estrategia: mapa mental, conceptual, historia, cuento)
Answer:
Sólido, líquido, gas y plasma.
Explicación:
Materia son las sustancias que ocupan espacio y tienen peso. Hay cuatro estados de la materia, es decir, sólido, líquido, gas y plasma. Todos los materiales presentes en este universo en estos cuatro estados. Los estados de la materia cambian con el aumento o la disminución de la temperatura del material. si la materia sólida se calienta, se derrite y cambia a estado líquido y luego gaseoso mientras que, por otro lado, la temperatura decreciente conduce a la condensación y congelación de la materia que causa el cambio de estado gaseoso a líquido y sólido. El plasma está formado por un gas de iones, átomos o moléculas.

Explain why biodiversity is essential to the health of an ecosystem Think about the complex interactions in an ecosystem and how different types of organisms respond to stable or unstable conditions Include evidence of factors that affect biodiversity and scientific reasoning to support your explanation
Answer:
Biodiversity is very essential to the health of an ecosystem.
Explanation:
Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.

How does genetic drift compare to natural selection?
A. The key distinction is that in genetic drift allele frequencies change by reproductive success, whereas in natural selection allele frequencies change by chance.
B. Distinction in genetic drift and natural selection is never by chance.
C. The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.
The key difference is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success. The correct option is C.
What is genetic drift?
Genetic drift is the change in frequency of an existing gene variant in the population due to random chance. Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It could also cause initially rare alleles to become much more frequent, and even fixed.
Natural selection is a natural process in which only the superior characteristics are moved to the next generations.
Therefore, the correct option is C. The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.

Mitosis vs. Meiosis answer chart
Answer:
why do cells divide is mitosis
mitosis is understood to involve five phases
how many daughter cells produced in mitosis two
how many daughter cells produced in meiosis four daughter cells
A condition in which every cell in the body has an extra set of chromosomes is not compatible with life. In some cases, a change in the number of chromosomes occurs only in certain cells. When an individual's cells differ in their chromosomal makeup, it is known as chromosomal mosaicism .
HOPE THIS helps
Explanation:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
[tex]\Large{\textbf{Mitosis:}}[/tex]
The cells undergo mitotic division to increase the number of cells to replace the worn out cells and for growth.In Mitosis, there are 4 stages, they are, Prophase, Metaphase, Anaphase and Telophase.In mitosis, cell divide once to form 2 daughter cells.In mitosis 2 daughter cells are produced.No, Chromosomal Number remains the same in mitosis i.e. 46.The final result of mitosis is two identical cells which are called daughter cells[tex]\Large{\textbf{Meiosis:}[/tex]
In meiosis, cells divide to produce gametes(i.e. sex cells) for the sexual reproduction.Meiosis occurs in 2 division i.e. Meiosis 1 and Meiosis 2(It is just Mitosis). The stages that are involved in these 2 division are 8.The stages of Meiosis 1 are,
(a) Prophase (which is sub-divided into 5 more stages which are Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis)
(b) Metaphase,
(c) Anaphase,
(d) Telophase.
The Stages of Meiosis 2 are, Prophase, Metaphase, Telophase and Anaphase which are same as mitosis.
3. In meiosis, Cell divides twice.
4. In meiosis, 4 daughter cells are produced.
5. Yes, the chromosomal number in mitosis is reduced to half than normal i.e. 23
6. In meiosis, the final result is 4 haploid cells. If meiosis occurs in male then these haploid cells will be called sperms, if it occurs in female then they are called Ova(egg).
_____________________________________Just to give you some insight knowledge of Meiosis Im adding some extra points
[tex]\Huge\textbf{Meiosis:}[/tex]
Meiosis is a special type of cell division, which occurs only in the germ cells during the process of development and maturation to form gametes. It consists of two successive cell divisions,
Meiosis 1 : First meiotic division, that reduces the NUMBER of chromosomes i.e. the parent cell is diploid(46 Chromosomes) and the daughter cells are haploid(23 Chromosome). It also causes genetic variation in the haploid by cross linkage.
Meiosis 2 : Second meiotic division (Meiosis II) starts with two haploid parent cells and ends with four haploid daughter cells. Meiosis 2 like Meiosis 1, does not reduce the NUMBER OF CHROMOSOME that means the forming 4 daughter cells are haploid and their number of chromosome remains the same as the parent. BUT Haploid cells that go into the meiosis 2 have MORE AMOUNT OF CHROMOSOME THAN USUAL, thus MEIOSIS 2 REDUCES the amount of chromosome rather than the number of chromosome.
The DNA of the primitive germs cells is replicated prior to the meiosis 1 only and there is no replication of DNA before Meiosis 2. The four final cells reulting from the two meiotic divisions are not only haploid(i.e. containing 23 chromosome) but they are also containing 1n amount of DNA so that when the gametes fuse together forming a zygote, both the amount and number of chromosome and DNA remains SAME.
_____________________________________
[tex]\Large\text{Why is Meiosis Important?}[/tex]
Meiosis is essential for the sexual reproduction of eukaryotic organisms because it enables genetic diversity through recombination, and the repair of genetic defects.
It contributes in genetic reassorment which ensures the genetic diversity in the offsprings. The genetic reassortment takes place by following two mechanisms:
During the prophase of meiosis 1, crossing over of genetic material between the homologous maternal and paternal chromosomes takes place which causes exchange of DNA fragments between the chromosome resulting is genetic diversity. During the anaphase of the first meiotic division, there is random distribution of maternal and paternal homologous chromosomes among the daughter cells which are produced as a result of meiotic division._____________________________________Best Regards,'Borz'

stage?
Answer:
Explanation: The concrete operational stage is the third stage in Piaget's theory of cognitive development. This period spans the time of middle childhood—it begins around age 7 and continues until approximately age 11—and is characterized by the development of logical thought. 1
Once the child reaches the Concrete Operational Stage, they can begin to separate and classify objects that are animate vs. objects that are inanimate. Children at the Concrete Operational Stage also have the ability to organize the items that they have classified. Seriation is the process is arranging items in a logical order.
