Explanation:
mitosis has 1 stage and meiosis had 2 stages.
Answer:
Mitosis and meiosis are nuclear division processes that occur during cell division.
Mitosis involves the division of body cells, while meiosis involves the division of sex cells.
The division of a cell occurs once in mitosis but twice in meiosis.
Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
Daughter cells resulting from mitosis are diploid (46 chromosomes), while those resulting from meiosis are haploid (23 chromosomes).
Daughter cells that are the product of mitosis are genetically identical. Daughter cells produced after meiosis are genetically diverse (genes swap during division).
Mitosis has 1 parent and meiosis produces 2 types of sex cells which fuse at fertilisation.
amylase and proteases
lipases
amylase, proteases, lipases, nucleases
Nucleases are the enzymes that are unique to the pancreas. These are enzymes which break down nucleic acids DNA and RNA into nucleotides. When these nucleotides reach the ileum, they are further degraded or digested into sugars, bases and phosphates. These nucleases are known as DNAase and RNAase
Other pancreatic enzymes such as amylase and protease are also produced by other digestive organs such as the salivary glands and the small intestine respectively. However no other digestive organ has been known to produce nucleases apart from the pancreas.
Nucleases are of two main types, namely exonucleases which cut off the end of a nucleotide and endonucleases which will cut out certain nucleotide sequences right in the middle of a nucleic acid.
The enzymes that are secreted only by the pancreas are amylase, proteases, lipases, and nucleases. Therefore, option (4) is correct.
Digestive organs include the pancreas. It secretes digestive enzymes into the small intestine to facilitate food digestion. Amylase breaks starches into sugar molecules. Trypsin and chymotrypsin break proteins into amino acids. Fatty acids and glycerol from lipases aid fat breakdown and absorption.
Finally, nucleases break down DNA and RNA into nucleotides. The pancreas exclusively produces and secretes these enzymes to aid small intestine digestion and absorption. Therefore, option (4) amylase, proteases, lipases, and nucleases is correct.

Answer:D. Heart and lung function
Explanation:the word “cardio” relates to the heart
Cardiorespiratory fitness refers to how efficiently the heart and lungs work together to deliver oxygenated blood to the muscles during exercise. It's essential for cardiovascular health, quality of life, and longevity.
Cardiorespiratory fitness refers to the ability of the heart and lungs (option d) to supply oxygen-rich blood to the working muscle tissues and the capacity of the muscles to use oxygen to produce energy for movement. This involves the circulatory and respiratory systems' abilities to transport oxygen throughout the body efficiently, maintaining overall health and stamina.
An individual with high cardiorespiratory fitness can sustain large-muscle, dynamic, moderate-to-high intensity exercise, such as walking, running, bicycling, and swimming, for prolonged periods. This capacity is critical for preventing cardiovascular diseases, improving quality of life, and promoting longevity.

Genetic testing is the scientific factor that has most advanced livestock breeding, as it allows breeders to identify specific genes and traits in animals, helping them make informed breeding decisions.
The scientific factor that has most advanced livestock breeding is genetic testing.
Genetic testing allows breeders to identify specific genes and traits in animals, helping them make informed decisions about which animals to breed.
By selecting animals with desired genetic traits, breeders can improve the quality and productivity of livestock over time.

Answer: heterotrophic, chitin in cell walls
Fungi is a group of eukaryotic organisms, which can be grouped into Kingdom of Fungi. This kingdom includes organisms ranging from small microorganisms such as yeast and molds to large mushrooms. The fungi are different from plants, animals and bacteria as they possess chitin in their cell walls. However, these organisms can be more related to animals rather than to plants as they cannot produce their own food by the process of photosynthesis like plants. These organisms are dependent upon other organisms and their dead remains to obtain their food.
Answer:
The correct answer is heterotrophic and chitin in cell walls.
Explanation:
Fungi refer to a kingdom of eukaryotic, heterotrophic species like the animals, as they attain their food from other species. That is, by captivating nutrients from the environment, either from the non-living or living organic matter. This is due to the fact that they do not contain chlorophyll pigment, unlike plants that are autotrophic in nature, as they produce their own food.
The fungi are non-vascular in nature, as they do not possess vascular tissues like phloem and xylem, unlike the plants. The cell wall of fungi is mainly formed of chitin, unlike plants that comprise cellulose in their cell walls.
