Study the diagram of gametogenesis where egg cells and sperm cells
undergo meiosis I and meiosis II. Note the number assigned to each cell.
Identify the number of chromosomes in the different cells, represented
by a circle, by writing the symbol N for haploid and 2N for the diploid.
Write your answers on a separate sheet of paper.
A diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.
What happen during the egg formation?During egg formation in the ovary, Primary oocyte (diploid) having 46 chromosomes undergoes meiosis I to form one secondary oocyte and one first polar body.
Both the secondary oocyte and one polar body are haploid having 23 chromosomes. Both daughter cells then undergo meiosis II, the first polar body divides to give two polar bodies and the secondary oocyte divides by meiosis II to form one ovum.
Therefore, during egg formation in the reproductive system, a diploid cell (a primary oocyte) undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

What helps an animal to look like another animal to stay protected from predators? *
(0/1 Point)
Answer: ADAPTIVE COLORATION
Explanation:
Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.
Adaptive coloration may be grouped into :
--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.
--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.
--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.

Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit
Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.

Complete question:
Which of the following statements is NOT correct about the flatworms?
A. There are three complete tissue layers.
B. Flatworms may be either free-living or parasitic.
C. Flatworms have a sac body plan, with only a mouth and no anus.
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Answer:
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
Explanation:
Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.
Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.
These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.
Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.

El vapor se puede transportar a través de la atmosfera. A medida que el vapor se enfría , el agua se condensa en gotitas y forman y forman nubes y da como resultado
Answer:
Precipitación.
Explicación:
El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.
de que sustancia esta lleno el cromosoma
Answer:
Los cromosomas están compuestos por dos cadenas largas de polinucleótidos asociados a proteínas histonas
Explanation:
Un cromosoma es una molécula lineal de ácido desoxirribonucleico (ADN) la cual está compuesta por dos cadenas de nucleótidos dispuestas en forma de doble-hélice. En el ADN, cada nucleótido está formado por una azúcar desoxirribosa, un grupo fosfato y un tipo de base nitrogenada (los cuatro tipos de bases nitrogenadas que forma nucleótidos en la molécula de ADN son Timina, Guanina, Citocina y Adenina). La molécula larga de ADN en doble hélice se encuentra asociada a proteínas histonas para formar las fibras de cromatina. Aproximadamente 150 pares de bases de la molécula del ADN se encuentran enrolladas con las histonas H2A, H2B, H3 y H4 (dos subunidades de cada una) para formar un nucleosoma, la unidad básica de la cromatina. Finalmente, es importante indicar que la molécula de ADN contiene regiones no codificantes y regiones codificantes, es decir, fragmentos de ADN los cuales son utilizados como templados para producir moléculas de ARN mediante un mecanismo conocido como transcripción. Los ARN mensajeros (ARNm) son un tipo especial de ARN sintetizados a partir de fragmentos codificantes de ADN conocidos como 'genes'. Posteriormente al proceso de transcripción, estos ARN mensajeros sirven a su vez como templados para la síntesis de proteínas en los ribosomas, mediante un mecanismo conocido como 'traducción'.

After a forest fire, which type of organisms will begin secondary succession?
small shrubs
mature oaks
evergreens
wildflowers
Small shrubs are the kind of organisms that start secondary succession after a forest fire. The correct option is A.
Thus, the term "secondary succession" describes the ecological recovery process that follows a disruption like a fire. Small shrubs have developed survival strategies that enable them to swiftly colonize damaged environments.
They have the capacity to emerge from subterranean structures once again or to create seeds that will take root in newly accessible sunshine and nutrients. Due to their quick growth and capacity to keep the soil stable, these shrubs facilitate the establishment and flourishing of other plant species.
Thus, the ideal selection is option A.
