What causes an ecosystem to move from a primary successional stage towards a relatively-stable mature ecosystem?
Answers
Answer:
The correct answer is "secondary succession, an ecological succession step where an area previously occupied by living beings is disrupted".
Explanation:
In ecological succession, an ecosystem changes and develops through a series of steps. The first step, is the primary successional stage where rocks or other sedimentary structures are colonized by microorganisms. The second step, where the ecosystems changes towards a relatively-stable mature stage, occurs when an area previously occupied by living beings is disrupted. This step is named secondary succession, and the most clear example of this phenomena occurs when wildfire clears oak and hickory forests.

Answers
The activities mentioned, such as gardening, quarrying, mining, deforestation, bad farming, and kaingin (slash-and-burn agriculture), can have negative impacts on the soil.
These activities disrupt the natural balance of soil ecosystems and can lead to soil degradation and damage. Gardening, when done improperly, can result in soil compaction and nutrient depletion. Quarrying and mining operations can strip away topsoil, leaving behind barren landscapes.
Deforestation removes the protective cover of trees, leading to soil erosion. Bad farming practices, such as overuse of chemical fertilizers and pesticides, can harm soil health and biodiversity. Kaingin, with its practice of burning vegetation, destroys organic matter and alters soil fertility.

Why does natural selection occur more when there is competition for resources?
Answers
Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.
In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.
Competition leads to differential survival and reproductive success among individuals.
Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.
These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.
Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.
Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.
Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Why do oestrogen levels between 8and 22days remain low in the women who takes contraceptive pills
Answers
Contraceptive pills suppress ovulation and keep oestrogen levels low throughout the menstrual cycle, preventing pregnancy.
The contraceptive pill contains synthetic hormones that mimic the effects of oestrogen and progesterone in the body.
These hormones work to suppress the natural production of oestrogen by inhibiting the release of follicle-stimulating hormone (FSH) and luteinising hormone (LH) from the pituitary gland.
This prevents ovulation and therefore reduces the levels of oestrogen that are normally produced during the menstrual cycle.
The low levels of oestrogen between days 8 and 22 of the menstrual cycle in women taking contraceptive pills are due to the fact that this is the time when oestrogen levels would normally peak in a natural menstrual cycle.
However, as ovulation is suppressed by the pill, there is no need for the body to produce high levels of oestrogen to support the development of the ovarian follicle.
Instead, the pill maintains a consistent level of synthetic hormones throughout the cycle, which prevents the fluctuation of oestrogen levels that would occur naturally.
Therefore, women who take contraceptive pills typically have lower levels of oestrogen throughout their menstrual cycle.

D- layer of gas at the bottom of the ocean that bubbles off when disturbed
Answers
Answer:
the answer is c
Explanation:
pretty simple
The ozone layer is best described as a layer of the atmosphere, rich in ozone gas, that protects the Earth's inhabitants from the harmful effects of UV radiation. The correct option is C.
The ozone layer is found in the stratosphere, a region of the Earth's atmosphere located approximately 10 to 50 kilometers above the Earth's surface.
It contains a higher concentration of ozone (O3) molecules compared to other parts of the atmosphere.
The ozone molecules in this layer absorb a significant portion of the incoming UV radiation from the Sun, thereby shielding living organisms on Earth from its harmful effects.
UV radiation can be harmful to human health and ecosystems.
Overexposure to UV radiation can cause sunburn, skin cancer, cataracts, and immune system suppression in humans.
Thus, the correct option is C.

A crane has a sharp and pointed beak while the duck has a flat beak.Explain why
Answers
Answer:
The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.
On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.
The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

Many countries generate their electricity using renewable energy resources such as wind turbines and solar panels.
i). Predict the effect of using renewable energy resources, rather than fossil fuels, on the carbon cycle .
ii). Explain the reason for your prediction.
Answers
i) Using renewable energy resources instead of fossil fuels will have a positive impact on the carbon cycle. This is because burning fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the atmosphere, contributing to climate change. In contrast, renewable energy sources such as wind and solar do not produce carbon dioxide emissions during their operation.
ii) The reason for this prediction is that the use of renewable energy sources reduces the amount of carbon dioxide released into the atmosphere. This, in turn, reduces the amount of carbon that is available for absorption by terrestrial and marine ecosystems. This can lead to an overall reduction in carbon cycling between the atmosphere, oceans, and land, and ultimately contribute to slowing down the process of climate change. Additionally, the use of renewable energy resources can also help to reduce the pollution of air and water caused by fossil fuel extraction and transportation, which can have negative impacts on the carbon cycle and ecosystem health.

5. Where in the cell is the information from the mRNA strand translated into a polypeptide chain?
A. The ribosomes
6. Why is gene regulation and expression important to all living organisms?
D. All of the above
The translation of mRNA into a polypeptide chain occurs in the ribosomes. The mRNA is transported to the ribosomes, where it is read by transfer RNAs (tRNA) and translated into a sequence of amino acids that make up a polypeptide chain.
Gene regulation and expression are important to all living organisms for multiple reasons. Specific signals trigger specific genes to be transcribed and translated, leading to the production of proteins that determine most of the organism's traits. Additionally, different phases of the life cycle require specific genes for growth and development, making gene regulation and expression crucial for the survival and reproduction of the organism.
What is the probability that unicorn offspring will have a white horn? Brown horn?
Answers
The probability that the offspring will have a white horn is 3 out of 4, or 75%.
In unicorns, the trait of having a white horn (W) is considered dominant over having a brown horn (w). When two heterozygous unicorns, each carrying one dominant white horn allele (W) and one recessive brown horn allele (w), are crossed, the probability of their offspring having a white horn can be determined using Punnett squares.The possible genotypes of the parent unicorns are Ww and Ww. When these genotypes are crossed, the potential offspring can inherit one of the following genotypes: WW, Ww, Ww, or ww. Out of these options, three of them (WW, Ww, Ww) contain at least one dominant white horn allele, resulting in a unicorn with a white horn. Therefore, the probability that the offspring will have a white horn is 3 out of 4, or 75%. This calculation is based on the assumption that the genetic traits are inherited independently and follow Mendelian inheritance patterns.For more questions on genotypes
