Which of the following facts about rain forest illustrates the negative effect of their destruction on the environment?
Answers
The release of carbon dioxide during the burning of the rainforest adds to the greenhouse effects.
What is greenhouse effect?The greenhouse effect occurs when energy from a planet's host star passes through its atmosphere and heats its surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space, resulting in a warmer planet.
The greenhouse effect describes how "greenhouse gases" trap heat near the Earth's surface. These heat-trapping gases act like a blanket wrapped around Earth, keeping it warmer than it would be without them.

inquiry based pedagogy is being embraced in principle across the globe. in the last decade , it has been supported by an increasing body of research on its effectiveness. illustrate your understanding of the concept of inquiry based pedagogy with a relevant example
Answers
Inquiry-based pedagogy involves fostering curiosity and active learning. For example, students investigating real-world environmental issues and proposing solutions.
Inquiry-based pedagogy is a teaching approach that promotes active learning and critical thinking through inquiry and exploration. One relevant example of inquiry-based pedagogy is a science classroom where students are encouraged to design and conduct their own experiments. Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.For more such questions on Pedagogy:

Answers
At the genetic level, biological evolution is a change in allele frequencies over time.
What is biological evolution?
In populations of organisms, biological evolution is the change in hereditary features through successive generations. Adaptation is a crucial evolutionary process in which natural selection modifies variance in the fitness of characteristics and species to make them better suited for survival in particular ecological settings. Therefore, understanding the mechanics of evolution requires understanding how developmental changes are mediated.
Model organisms are used frequently to study biological processes. A model organism is a species that is thoroughly researched in the lab with the hope that the findings will be applicable to various biological processes.

THINK IT THROUGH You may recall that soil is classified by several properties such as color, texture, structure, and pH. Many of the processes that produce soil are related to the activities of living things. Do you think that the types of rocks and minerals found in a particular area could also influence the characteristics of the soil? Explain.
Answers
Answer:
Yes, the types of rocks and minerals found in a particular area can influence the characteristics of the soil. This is because soil formation is a complex process that involves the weathering and breakdown of rocks and minerals over time.
For example, if an area has a high concentration of granite rocks, which are composed of minerals such as quartz, feldspar, and mica, the resulting soil may be sandy or gritty in texture and have a higher pH due to the presence of minerals that do not easily break down. On the other hand, if an area has a high concentration of limestone rocks, which are composed of calcium carbonate, the resulting soil may be alkaline and have a higher fertility due to the presence of easily broken down minerals.
In addition, the type of rocks and minerals in an area can also influence the structure of the soil. For instance, if an area has a high concentration of clay minerals, which are formed from the weathering of silicate rocks such as feldspar and mica, the resulting soil may have a higher water-holding capacity and be more susceptible to compaction.
Therefore, the type of rocks and minerals in an area can have a significant impact on the characteristics of the soil, including its texture, structure, and pH, as well as its fertility and water-holding capacity.

In peas, purple flowers are dominant to white and tall plants are dominant to short. A white and short plant is crossed with a plant that is heterozygous for both traits.
Answers
to understand what the result of these crosses would be like, we need to know what is gene
Gene
The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.
Genes can be classified into:
Dominant genes: assume the specific characteristic in the offspring; Recessive genes: manifests itself in the absence of the dominant gene; Structural genes: are those that contain the information that will determine the structure of living beings; Operator gene: acts on the functioning of other genes; Regulatory gene: responsible for controlling the synthesis and transcription of other genes.
in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.
with this information we can say that a white and short plant, when crossed with a plant for both traits, has 60% of this plant being with expression of the dominant genes and 40% of being with expression of the recessive gene.

Answers
As we know each time energy passes from trophic level to trophic level, a smaller amount of energy passes generally is applied the 10% rule, that is to say, that only te 10% of the energy in one level will pass to the second level, so if we apply this into the current problem we have that level 1 are producers, and the second level receives only 10% of the 25,000 available kilocalories, which is 25,000X0.10= 2,500, therefore the correct answer is the second option.

Answer:
About bacterial fimbriae, the statement that is not correct is that they protect the cell from dehydration.
Explanation:
Bacterial fimbriae are extensions of the cytoplasmic membrane, predominantly of a protein nature, which give the bacteria the ability to adhere to surfaces, tissues or other bacteria.
These pilous structures can be present in all bacteria, constituting a factor related to their infectious capacity. The main function of fimbriae is adhesion, so they do not constitute a protective element against dehydration.
The other options correspond to true characteristics of the bacterial fimbriae.

To answer this question we need to decompose the question into two parts, first, why global carbon levels are the same, this has only one explanation, and this is because the amount of carbon on earth is constant, that is to say, the carbon on earth follows a cycle, can be in different forms but there are no new sources, there is no new carbon income into the planet, therefore, it does not matter how carbon is distributed on earth the quantities will remain the same.
Now for the atmospheric levels that is a whole new story and a very controversial topic, as global warming and carbon dioxide excess in the atmosphere increases some argue that is due to a natural phenomenon meanwhile others attribute it to human activity, so let's explore this two postures. In past eras there is a record of an increase in carbon dioxide due to intense volcanic activity, in the actual time it is said that this is due to natural activity and we are relieving a natural cycle due to volcanic activity, natural greenhouse effect, natural carbon dioxide as a subproduct of respiration and organic matter decomposition. On the other hand, there is the posture of human activity and the increase is given mainly by an excess of burning oil and subproducts (industrial processes, car driving among others), also intense clearing leading to massive deforestation decreases photosynthetic rate on earth, also water contamination leads to the loss of other photosynthetic organisms such as cyanobacteria and algae another important sink of carbon. Finally, there is a third explanation that what we are actually seeing is a combination of both processes natural and human, and together they make synergy, this posture has been recently gaining attention as there is proof of both causes, nonetheless, it is our responsibility to reduce our human impact.

Plants can reproduce both sexually and asexually. What are some examples of sexual reproduction in plants? Select ALL that apply. Responses
Answers
Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic diversity.
Mechanisms that facilitate sexual reproduction in plants are examples:
1)Pollination and Fertilization: Many plants rely on pollinators, such as bees, butterflies, or birds, to transfer pollen from the male reproductive structures (anthers) to the female reproductive structures (stigma) of flowers.
This process enables the fusion of sperm cells within the pollen with egg cells in the ovules, leading to fertilization.
Examples include flowering plants like roses, sunflowers, and apple trees.
2)Seed Production: After fertilization, the ovule develops into a seed. Seeds contain an embryo, formed by the fertilized egg, enclosed within a protective seed coat.
The mature seeds can disperse and germinate to give rise to new plants.
Various plant groups, including angiosperms (flowering plants) and gymnosperms (conifers and cycads), reproduce sexually through seed production.
3)Alternation of Generations: In plants with a complex life cycle, such as ferns, mosses, and liverworts, sexual reproduction involves an alternation between two distinct generations: the gametophyte and the sporophyte.
The gametophyte generation produces gametes (sperm and eggs) through specialized structures, while the fusion of gametes gives rise to the sporophyte generation, which produces spores.
4)Self-fertilization: Some plants have the ability to self-fertilize, where the pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.
This allows for sexual reproduction without the need for external pollinators. Self-fertilization can be seen in plants like tomatoes, peas, and certain grass species.

In individual is asked to smile broadly. It is observed that the left corner of the mouth cannot be elevated in a normal fashion. The individual is then asked to wrinkle the brow. The brow is observed to wrinkle in a normal fashion. Which cranial is involved in this facial control issue, and is the lesion in that nerve or within the central nervous system?
Answers
Answer:
Cranial nerve 7 and YES the lesion is within the Central Nervous System.
Explanation:
The Central Nervous System ( CNS) consists of the brain and the spinal cord. There are 12 pairs of cranial nerves originating from the nuclei in the inferior surface of the brain, some sensory, some motor and some mixed.
Cranial nerve 7 is also known as the Facial nerves. These nerves are composed of both motor and sensory nerve fibre, arising from nuclei in the lower part of the pons. The motor fibres supply the muscles of facial expression. When lesion occurs at the base of the pon which is part of the CNS, it can affect the facial expressions such as observed, that the left corner of the mouth cannot be elevated in a normal fashion.
Therefore, Cranial nerve 7 ( Facial nerve) is involved in this facial control issue and YES the lesion is within the Central Nervous System.
