Answer: A. secondary succession

An ecological succession is a phenomena which involves gradual series of events which brings changes in the biotic community of the ecosystem with respect to changes in the non- living factors such as soil, water, natural calamity like (forest fire, drought, flood) and time until the ecosystem attains stability. Secondary succession occurs in an area which was previously colonized by floral and faunal species but was disturbed by natural or man-made calamity like forest fire, clear-cut, drought, flooding.The ecosystem again attain colonization due remains of biological species and suitable abiotic factors such as soil, water, weather. Secondary succession is most likely to occur immediately after a rainforest in Brazil is clear-cut as secondary succession facilitates quicker compensation for damage and loss in an ecosystem.      

Answer:

Model                0M      5M      10M      15M     20M    25M     30M    35M     40M

Conglomerate  600g  590g   580g   520g   500g  460g    300g   210g    105g

Plain                 280g  260g   260g   250g   240g   235g    220g   215g   210g

In view of the chart and information table, the dissolving pace of both models is started gradually. As time proceeded with the plain model proceeded at a fundamentally the same as rate. The Conglomerate model was distinctive on the grounds that it expanded its dissolving rate gigantically from 25 minutes to 40 minutes.

Final answer:

A medium-sized star is about the size of our Sun, which is approximately 1.4 million kilometers in diameter. Most nearby stars are of similar size, and the Sun is brighter and more massive than about 80% of the stars in the Galaxy.

Explanation:

When considering the size of a medium-sized star, one can generally refer to a star that is about the size of our Sun. The Sun itself has a diameter of approximately 1.4 million kilometers. Most nearby stars have typical diameters around this scale, fitting the definition of a medium-sized star. However, there is a diverse range of star sizes, with some much smaller and others much larger than our Sun.

Various measurements and observations indicate that while there are exceptions, a significant number of stars fall within the spectrum of being medium-sized, implying sizes that are quite similar to our Sun. Stars significantly more massive than the Sun are quite rare within our local cosmic neighborhood; within 30 light-years of the Sun, none exceeds four times the mass of the Sun.

The Sun is also more massive than most of the stars in our vicinity, being brighter than about 80% of the stars in the Galaxy, further underscoring its qualification as a medium-sized star. Therefore, when referencing a medium-sized star, the size of our Sun serves as an apt comparison.

A solar eclipse is when the Moon blocks the Sun's rays from reaching the Earth. The Moon must be precisely aligned with the Sun and Earth. There are total and partial solar eclipses, depending on whether the Moon's shadow completely or only partially blocks the Sun.

A solar eclipse occurs when the Moon moves between the Sun and Earth, casting a shadow on Earth, and temporarily blocking the Sun's rays from reaching Earth. The correct answer to the student's question is (C). A solar eclipse is when the moon blocks the sun's rays from reaching the Earth. During a total solar eclipse, the Moon's umbra (the darkest part of its shadow) intersects with Earth's surface and completely obscures the Sun's light from view in a small area, allowing observers to see the Sun's corona. If only part of the Sun is covered, resulting in some sunlight still reaching Earth, it is called a partial solar eclipse. Solar eclipses are relatively rare because they require the Sun, Moon, and Earth to be precisely aligned in the same plane, known as the ecliptic.

The tarsals are seven bones in the ankle that transmit body weight from the tibia and fibula to the foot. They play a crucial role in balance, shock absorption, and efficient movement. Key tarsal bones include the talus, calcaneus, navicular, cuboid, and three cuneiforms.

Function of the Tarsals

The tarsals are the seven bones that make up the ankle. The ankle's primary function is to transmit the weight of the body from the tibia and fibula to the foot. The seven tarsal bones include the talus, calcaneus, navicular, cuboid, and three cuneiform bones.

The talus articulates with the tibia and fibula superiorly, forming a joint that allows for the up-and-down motion of the foot. The calcaneus, or heel bone, is the largest of the tarsals and supports much of the body's weight when standing or walking.

The other tarsal bones (navicular, cuboid, and three cuneiforms) help to form and support the arch of the foot, which provides additional shock absorption and aids in the ability to move efficiently and maintain balance. This arch is crucial for activities like walking, running, and jumping.

Genes are the hereditary unit, which transmits the genetic information from the parent to the offspring. Human-made and environmental factors can influence the expression of genes.

Thus, environmental factors such as sunlight, water, temperature, and oxygen level influence the genetic expression in organisms.

Answer:

organ system

Explanation:

An example of an organ system is the digestive system which is made of multiple organs such as the mouth, stomach, iliuem, deodenum, rectum, anus etc which are all working together to ingest food, break it down into soluble nutrients and eject undigested food.

Answer: a. Mitochondria and chloroplasts contain their own set of DNA.

Explanation:

The theory of endosymbiosis suggests that origin of mitochondria and chloroplast in eukaryotes were the individual primitive prokaryotic organisms. The mitochondrial and chloroplast DNA and protein synthesis was found similar to the bacteria. This provided the evidence for endosymbiotic hypothesis. It was determined that chloroplast as well as mitochondria divide independently in the cell where they live just like individual bacterial cell.

Answer:

Option A, 75 percent

Explanation:

Given -

Allele for widow’s peak (W) is completely dominant over the allele for a straight hairline (w).

A cross is carried between two parents that are heterozygous for a widow’s peak

Thus, the  offspring produced by the cross between two parents with genotype "Ww" is

Ww * Ww

WW, Ww, Ww, ww

Except "ww" genotype all the remaining offspring have widow's peak.

Thus, the probability of two parents heterozygous for a widow’s peak (Ww) having an offspring with a widow’s peak is

[tex]\frac{3}{4} * 100\\0.75*100\\75[/tex]%

Hence, option A is correct.

Answer: Ribosome assembly begins in the nucleolus a structure deep inside the cell's nucleus. The nucleolus is where ribosomal proteins combine with four rRNA strands to create the two ribosomal subunits that make up the completed ribosome.

Explanation:

A sea star egg transferred from the ocean to a freshwater environment, such as Elk Lake, is likely to swell due to lower salinity, resulting in osmosis where water moves into the egg to balance the solute concentrations. The sensitivity of sea star eggs to their environment makes them susceptible to these changes, which could impact their development.

If a sea star egg is transferred from the ocean to Elk Lake, we can anticipate that the egg might either shrink or swell depending on the salinity differences between the ocean and the lake. Sea water is typically saltier than lake water. This difference in salinity can cause osmosis, which is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. Consequently, if Elk Lake has a lower salinity compared to the ocean, the sea star egg would likely swell as water enters to balance the internal and external solute concentration. Conversely, if Elk Lake is saltier, the egg might shrink as water exits the egg to balance the solute concentration. However, considering that most lakes are less salty than oceans, the more common scenario would be for the egg to swell. It is essential for the sea star's development that it is in an environment similar to its natural habitat.

Moreover, the phenomenon where sea stars can reproduce from fragments, known as fragmentation, implies that sea star eggs are sensitive to their environment and that the parent organism may employ certain strategies to protect its offspring from unfavorable conditions such as enclosing the egg in an isotonic fluid. Thus, introducing a sea star egg into a new environment is complex and fraught with challenges, potentially leading to detrimental effects on the egg's capacity to develop properly.
