Why do plant cells need cell walls? What is it made up of?
Answer: The cells walls are tough, flexible, and sometimes rigid. And these are perfect for a defense. Plant cells require the cell wall for protection against variations in temperature, high wind speed, atmospheric moisture, among other things. The cell wall is located just outside the cell membrane and it is made up of Cellulose and Peptidoglycan. The “peptide” part of the substance is from short chains of amino acids called peptides. The “glycan” part is long chains of sugars which along with the peptides make up the mesh of the cell wall.

What is it called when a species not native to an area species that invade the ecosystem and outcompete the native species causing the native species to decline potentially to extinction?
The phenomenon where a non-native species invades an ecosystem and outcompetes the native species causing the native species to decline potentially to extinction is called "invasive species.
It occurs when non-native species, also known as invasive species, establish themselves and thrive in an ecosystem, causing harm to the native species. Invasive species possess traits that give them a competitive advantage over the native species, such as rapid reproduction, efficient resource utilization, and resistance to local predators or diseases.
The consequences of biological invasions can be severe. The invasive species can outcompete native species for resources like food, habitat, and water, leading to a decline in native populations.
They may also directly predate upon or introduce diseases to native species, further exacerbating their decline. In some cases, the native species are pushed to the brink of extinction or even driven to extinction.
Biological invasions are a significant global concern due to their ecological, economic, and social impacts. They can disrupt ecosystem functioning, alter natural habitats, reduce biodiversity, and cause economic losses in industries like agriculture, forestry, and fisheries.
Efforts are made to prevent and control invasive species through monitoring, early detection, and management strategies such as eradication, containment, and control programs to mitigate their negative effects and protect native species and ecosystems.

potassium balance and imbalance self assessment can you identify the symptoms of hypokalemia and hyperkalemia by looking at the image
Hypokalemia describes low potassium levels in the blood. Potassium is necessary for our body to function properly.
The foods you eat provide potassium for your body. When you vomit, have diarrhoea, or use laxatives frequently, your digestive system loses a lot of potassium, which can lead to hypokalemia. Other causes include a few hereditary and adrenal disorders, as well as some drugs.
Serum sampling is used to identify hyperkalemia, which is characterised by a serum potassium level greater than 5.5 mEq/L. When there are no ECG abnormalities and the patient has normal renal function, laboratory mistake from a hemolyzed material should be regarded as a possible cause of hyperkalemia.

How is this method of reproduction advantageous to the honeybee colony?
The method of reproduction in honeybee colonies, known as swarming or colony division, has several advantages for the colony; Increase in colony size, Genetic diversity, and reproduction.
Swarming allows the honeybee colony to increase its population and overall size. When a colony becomes overcrowded, the queen and a portion of the worker bees leave the original hive to form a new colony, taking with them the resources needed to establish a new colony.
Swarming helps in promoting genetic diversity within honeybee colonies. When a colony swarms, the original queen leaves with a group of workers, and a new queen is raised in the original hive from eggs laid by the existing workers.
Swarming is a natural means of colony reproduction, allowing honeybee colonies to reproduce and potentially establish new colonies in different locations. This increases the chances of survival and reproduction of the honeybee colony as a whole, as it can establish new colonies in favorable locations with ample resources.

State 5 effects of exercise with varying intensity on the immune system.
Varying intensity of exercise can result in different effects on the immune system, such as increased natural killer cell activity, decreased inflammation, improved antibody response, increased white blood cell count, and increased cytokine production.
What are the 5 effects of exercise with varying intensity on the immune system?Here are 5 effects of exercise with varying intensity on the immune system:
Moderate Intensity Exercise: Regular moderate intensity exercise has been shown to enhance immune function by increasing the circulation of immune cells and antibodies in the body.
High Intensity Exercise: Short-term high-intensity exercise can lead to temporary suppression of the immune system. This is because intense exercise causes stress on the body, leading to the release of stress hormones that can suppress immune function.
Chronic Intense Exercise: Prolonged, intense exercise can lead to a decrease in immune function and increase the risk of infection if the body is not given adequate time to recover.
Resistance Training: Resistance training has been shown to boost immune function by increasing the production of immune cells.
Aerobic Exercise: Aerobic exercise has been shown to boost the immune system by increasing the number of natural killer cells, which are a type of immune cell that helps to fight off infections. Aerobic exercise can also increase the circulation of immune cells and antibodies in the body, improving immune function.

Q3: Classify the parasites that cause human disease; give an example for each one
.and Mention the name of disease, location in host, and the mode
transmission of these parasites .
Parasites that cause human disease can be classified into different groups based on their characteristics and the diseases they cause. Here are some examples:
1. Protozoa:
- Example: Plasmodium falciparum
- Disease: Malaria
- Location in Host: Plasmodium parasites reside and multiply within red blood cells.
- Mode of Transmission: Mosquitoes (Anopheles species) transmit the parasite to humans through their bites.
2. Helminths (Worms):
- Example: Ascaris lumbricoides
- Disease: Ascariasis
- Location in Host: Adult worms reside in the small intestine.
- Mode of Transmission: Ingestion of eggs present in contaminated food, water, or soil.
3. Nematodes (Roundworms):
- Example: Enterobius vermicularis
- Disease: Enterobiasis (Pinworm infection)
- Location in Host: Adult worms inhabit the large intestine, while females migrate to the perianal area to lay eggs.
- Mode of Transmission: Ingestion of infective eggs, which are usually transferred from contaminated surfaces or through direct contact with an infected person.
4. Trematodes (Flukes):
- Example: Schistosoma mansoni
- Disease: Schistosomiasis (Bilharzia)
- Location in Host: Adult worms reside in the blood vessels surrounding the intestines and liver.
- Mode of Transmission: Contact with water bodies infested with freshwater snails that release the parasite larvae, which can penetrate the skin of humans.
5. Cestodes (Tapeworms):
- Example: Taenia solium
- Disease: Taeniasis (Tapeworm infection)
- Location in Host: Adult worms reside in the human intestine, where they attach to the intestinal wall.
- Mode of Transmission: Consumption of undercooked or raw contaminated meat containing the larvae or ingestion of food or water contaminated with eggs.
It's important to note that this list provides only a few examples, and there are numerous other parasites that can cause diseases in humans. The diseases mentioned here represent a fraction of the many parasitic infections that can occur, and each parasite has its unique characteristics, geographical distribution, and mode of transmission.

In Leonardo da Vinci’s time, nobody knew that the arteries were joined to the veins by tiny, invisible capillaries. This means that even though he studied the heart in detail, he thought that the arteries and veins were dead ends. Why did this make it difficult for him to understand how the heart worked?
Answer:
It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.
Explanation:
Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

In biology, autotrophs are organisms that can produce their own food using inorganic substances, such as sunlight and carbon dioxide.
How do we explain?Autotrophs are also known as primary producers because they form the base of the food chain by converting energy from the environment into organic compounds.
The topic of autotrophs is typically covered in the study of plant biology in the context of a class 7 curriculum.
The most prevalent kind of autotrophs are plants. They do this through a process known as photosynthesis, which turns carbon dioxide, water, and sunlight into glucose (a sugar) and oxygen.
Chloroplasts, specialized organelles found in plant cells, are where this process occurs.
