Seeds are reproductive or not ?
Answers
Answer: Yes
Explanation: Monocots produce one cotyledon, while dicots produce two. Because seeds are reproductive structures and thus important to a species' survival, plants have evolved many mechanisms to ensure their survival. One such mechanism is seed dormancy. Dormancy comes in two forms: seed coat dormancy and embryo dormancy
Answer:Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.
Give a brief description of how viruses spread.
Answers
Viruses spread by infecting cells and replicating within them. There are several ways that viruses can spread from one person to another:
Direct contact: Viruses can be spread through direct contact with an infected person, such as through shaking hands or hugging.
Indirect contact: Viruses can also be spread through indirect contact, such as by touching a surface or object that has been contaminated with the virus and then touching one's face, mouth, or eyes.
Respiratory droplets: Some viruses, such as the virus that causes COVID-19, are spread through respiratory droplets that are produced when an infected person talks, coughs, or sneezes. These droplets can land in the mouths or noses of people who are nearby or be inhaled into the lungs.
Sexual contact: Some viruses, such as HIV and herpes, are spread through sexual contact.
Overall, viruses can spread through a variety of means, and the specific method of transmission can depend on the specific virus and the mode of infection.

Tc. How could a higher rate of "reusing, reducing, or recycling" change the way money is spent within a society? (1 point)
Answers
A higher rate of "reusing, reducing, or recycling" can change the way money is spent within a society by promoting a more sustainable and resource-efficient economy.
When individuals and communities prioritize reusing, reducing, and recycling, they are likely to consume fewer resources and generate less waste. This shift in consumption patterns can result in cost savings for both individuals and businesses. By reusing items instead of purchasing new ones, people can save money on buying replacements. Similarly, reducing the consumption of goods and resources can lead to reduced expenses for both individuals and businesses.
Furthermore, recycling materials instead of disposing of them as waste can create economic opportunities. Recycling processes can generate income through the recovery of valuable materials that can be reused or repurposed. This can lead to the development of recycling industries and the creation of jobs within the recycling sector.
Overall, a higher rate of reusing, reducing, or recycling can lead to financial benefits for individuals and society as a whole. It promotes resource efficiency, reduces waste generation, and can create economic opportunities through cost savings and the development of recycling industries.

Now choose one of the resources used for energy production that you have studied in this lesson. Describe how the way humans use or obtain this resource might impact the natural resource you described in part A. If you don’t think the natural resource in part A is affected, explain why.
Answers
Answer:
HERE
Explanation:
One resource used for energy production that can impact the natural resource of ozone layer depletion is coal. Burning coal releases pollutants like sulfur dioxide, nitrogen oxides, and mercury into the atmosphere, which can contribute to the formation of smog and acid rain. These pollutants can also react with other chemicals in the atmosphere to break down ozone molecules, contributing to the depletion of the ozone layer. So, the way humans use coal as an energy resource can have a negative impact on the ozone layer and the environment.
Which specialized cells help support the skeletal fibers in the cell?
Answers
Osteoblasts and osteocytes, specialized cells found in bone tissue, help support the skeletal fibers in the cell.
Osteoblasts and osteocytes are specialized cells that help support the skeletal fibers in the cell.
Osteoblasts: These cells are responsible for the formation of bone. They synthesize and secrete collagen and other proteins that make up the extracellular matrix of bone tissue. Osteoblasts also regulate the mineralization process by depositing calcium and other minerals onto the collagen matrix.Osteocytes: Once osteoblasts become surrounded by the bone matrix they have produced, they mature into osteocytes. Osteocytes are the most abundant cells in mature bone tissue. They are located in small spaces called lacunae and communicate with each other and with osteoblasts through tiny channels called canaliculi.Support for skeletal fibers: Osteoblasts and osteocytes play a crucial role in supporting the skeletal fibers in the cell. Osteoblasts actively produce and deposit the bone matrix, while osteocytes maintain and regulate the mineralization and remodeling of bone tissue. Together, these cells provide the structural support necessary for the integrity and strength of the skeletal fibers.In summary, osteoblasts and osteocytes are specialized cells that work together to support and maintain the skeletal fibers in the cell, contributing to the overall structure and function of the skeletal system.

Select a potted plant from the garden and keep it in a room for five days as shown in the diagram. After five days, you can see that most of the leaves of the plant change yellow. What could be a systematic method to ask right questions? Make a hypothesis or educated guess, conducting scientific experiment and activities about the existing facts to figure out a conclusion in accordance with the scientific learning process.
Answers
Answer:
Explanation:
To systematically investigate the yellowing of the plant's leaves, you can follow these steps:
1- Observation: Observe and note that after five days in the room, most of the plant's leaves have turned yellow.
2- Question: Ask yourself, "Why did the leaves of the potted plant turn yellow after being kept in the room for five days?"
3- Hypothesis: Make an educated guess about the possible cause of the yellowing. For example, you could hypothesize that the lack of sunlight in the room caused the leaves to turn yellow.
4- Experiment: Design an experiment to test your hypothesis. Place another potted plant in a different room with similar conditions but with sufficient sunlight.
5- Data collection and analysis: Record and compare the condition and color of the leaves in both plants after five days. If the plant with sunlight has green leaves while the one in the room still has yellow leaves, it supports your hypothesis.
6- Conclusion: Based on your observations and the results of the experiment, conclude that the lack of sunlight may be the cause of the yellowing of the plant's leaves.
By following these steps, you can systematically ask the right questions, form a hypothesis, conduct an experiment, and reach a conclusion using the scientific learning process.
Hope it helps!!! :)
A systematic method to ask the right questions, make educated guesses, conduct scientific experiments, and arrive at a conclusion is to follow the scientific method as follows:
Make observationsAsk questionsFormulate a hypothesisDesign and conduct experimentsCollect and analyze dataDraw a conclusionA hypothesis could be; The yellowing of the plant's leaves is a result of reduced exposure to sunlight.
Why do the leaves of a potted plant kept away from sunlight turn yellow?The yellowing of leaves in a potted plant kept away from sunlight is primarily due to a process called chlorosis which is the loss or reduction of chlorophyll in plant tissues.
When a potted plant is kept away from sunlight or receives insufficient light, the plant is unable to carry out photosynthesis. Consequently, the chlorophyll content in the leaves decreases, and they start to lose their green color.

What caused the change in the fireballs velocity as it traveled
Answers
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity. Have a blessed day!! :D
Force caused the change in the fireballs velocity as it travelled.
What do you mean by force?A force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull.
A force is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium.
