Primary succession occurs after the occurrence of a severe event that leaves nothing but rocky surfaces. Option B. Lichens will grow on the cooled lava.
What is succession?
The succession term refers to colonization and subsequent changes.
Colonization has been defined as the sequence of events that conduce to the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
Succession refers to changes produced in the composition and structure of communities after a perturbation. There are different grades of succession according to the perturbation intensity.
What is Primary succession?In primary succession, the perturbation is so intense that it eliminates all the life forms in the area.
It is the sequence of species appearance in an exposed area that has not been influenced by any other species or community before.
In these cases, the rock gets exposed but it can not be colonized directly. The new area needs to suffer erosion and different chemical and physical processes that fragment, degrade and dissolve the rock to make colonization possible.
Primary succession occurs after severe events affecting a region, such as a retreating glacier, a volcanic activity, or an intense fire that leave nothing but the exposed rock.
After the disturbance, the order of the living beings establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space.
Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses.
Grasses and pioneers keep modifying the ground and making it better with time.
Habitat modification keeps on going while new species establish. They produce shadows and alter the temperature, and humidity, fertilizing the soil.
Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources.
This sequence continues until there is no more facilitation, and the communities reache a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
In the exposed example, the severe event affecting the Hawaii's Big Island was a volcanoe eruption.
The most likely event observed first in the areas covered by lava would be Lichens will grow on the cooled lava. Option B

What is mitosis and why is it important to an organism?
☁️ Answer ☁️
What is mitosis?
Mitosis definition is the division of the mother cell into two daughter cells genetically identical to each other.
✨
Why is it important?
Mitosis is important because it is essential for growth and repair in the body. Mitosis happens when a parent cell divides, creating two identical copies, referred to as daughter cells.

Answer:
B
Explanation:
Pregunta de ecología: ¿Cuáles factores ecológicos afectan a los ecosistemas acuaticos? - Describe cómo afecta cada uno de estos factores, a los ecosistemas acuáticos.
Answer:
Salinidad, acidez, oxígeno, niveles de luz y temperatura.
Explicación:
Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.
Examine the genotype for an individual who is AaBbCcDd. Predict the outcomes of meiosis and the potential gamete combinations
that could form from this individual. Select ALL that apply.
A)
50% of the gametes will be AaBbCcDd.
B)
1/16 of the gametes produced will be ABcd.
The individual could make gametes that contain ABCD.
D)
The individual could make gametes abcd half of the time.
E)
Only dominant traits will be present in the gametes from a heterozygous
individual
Answer: B,C
Explanation:
I did just did the USA test prep
The outcomes of meiosis and the potential gamete combinations that could form from the genotype for an individual who is AaBbCcDd:
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.
A a simple method to calculate the number of gametes:
Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.n = 4
Then, total number of gametes will be = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16Thus 16 in this condition
The 16 types of gametes are formed by this individual by permutation and combination are:
ABCD, AbCD, ABcD, ABCd,
ABcd, AbcD, ABCd, Abcd,
aBCD, aBCd, aBcd, aBcD,
abCD, abCd, abcd, abcD.
Thus, the correct answer is -
B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.Learn more about permutation and combination:

necesito un impacto negativo de la biodiversidad del mosquito aedeomyia squamiennis
ayuda:/
Answer:
El cambio climático tiene un impacto negativo.
Explicación:
El impacto negativo en la biodiversidad del mosquito aedeomyia squamiennis se debe al cambio climático que disminuye su población porque el cambio climático hace que el medio ambiente sea desfavorable para el mosquito. Debido a este cambio climático, aquellos organismos que se adoptan de acuerdo con el cambio ambiental pueden sobrevivir pero aquellos que no pueden extinguirse del medio ambiente, por lo que podemos decir que el cambio climático tiene un efecto negativo en la biodiversidad del mosquito aedeomyia squamiennis.

Title: Does temperature have an effect on growth rate of crystals? what about leaving them covered or uncovered? Does dry air or moist air seem to grow more crystals
Hypothesis:
IF
THEN
BECAUSE
Help pls
Answer:
Temperature also affects the growth of crystals because "the higher the temperature, the warmer the crystal solution will be, and the faster its molecules will move. This movement allows them to evaporate more quickly, leaving particles behind to form into crystals.
Explanation:
A Warm and Light Atmosphere
Warm air temperature aids water evaporation, causing the crystals to grow more quickly. Crystals will still grow in cooler temperatures, but it will take much longer for the water to evaporate. Crystal growth also requires light.

remove dirts using hard cloth
Answer:
It can easily remove dirt.
Explanation:
When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.
