Explanation

• The nucleus is responsible for cell division because it contains chromosomes, which are made up of DNA and proteins.
• Chromosomes carry the genetic information necessary for cell division, growth, and function.

Explanation

Alleles of a gene are located at the same locus on homologous chromosomes.

A locus refers to a specific location or position on a chromosome where a particular gene is located.

Explanation

• Photosynthesis occurs during daytime because it depends on sunlight, which provides the energy necessary for the process to occur.
• Sunlight is the source of light energy that is absorbed by pigments such as chlorophyll.
• Which is then used to power the conversion of carbon dioxide and water into glucose and oxygen.

Explanation

• During the daytime, plants require Carbon Dioxide (CO2) for photosynthesis.
• Which is the process by which they produce glucose and oxygen.

Explanation

This is the photosynthesis reaction, where carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) in the presence of light energy.

Explanation

• Fungi are multicellular organisms, consisting of many cells that work together to form complex structures like mushrooms and molds.
• They have modified cell wall and nucleus.
• They have not chlorophyll.
• Animals, including humans, are multicellular organisms made up of many cells that work together to form tissues, organs, and systems.
• They have modified nucleus but don't have cell wall.
• They have not chlorophyll.
• Bacteria are unicellular organisms.
• They have cell wall but don't have proper nucleus.
• It doesn't contain chlorophyll.
• It is used to make medicines, yogurt and cheese.

Explanation

Signet ring cells are a hallmark of certain types of gastric cancer

Specifically signet ring cell carcinoma

Explanation

In the absence of sunlight, the entire food chain would become inactive and collapse because:

• Plants and algae, the primary producers, cannot undergo photosynthesis and produce energy.
• Herbivores cannot feed on plants, and carnivores cannot feed on herbivores.
• The energy flow from producers to consumers would be disrupted, leading to a collapse of the food chain.

Explanation

• Animals in grassland environments have broad feet or hooves that help them escape quickly from predators, such as lions, cheetahs, and hyenas.
• The broad feet provide stability and support for rapid movement, allowing them to run fast and efficiently.

Explanation

• Iron Rock is a non-living component, an abiotic factor.
• It is not included in the living components of the land environment.
