Explanation:
(1) mitosis of sex cells
(2) mitosis of body cells
(3) meiosis of sex cells
(4) meiosis of body cells
Answer: The correct answer is-
(2) mitosis of body cells.
Mitosis is a type of cell division in which a parent cell produces two daughter cells having same number of chromosomes as that of their parent cell.
It occurs through a series of 5 stages that are- Prophase, metaphase, anaphase, telophase, and cytokinesis.
It is responsible for the growth of organisms and the repair of damaged tissues (in case of multicellular organisms) as new, identical cells (that are identical to each other) are produced from the parent cell.
Thus, option 2) is the right answer.
Answer:
2) mitosis of body cells

The safest fish to consume raw are tuna and farmed salmon. Mostly because they are the least likely to have parasite....!!
The safest seafood choice for sushi is fish that has been either frozen or cooked to eliminate the risk of parasites. Pregnant women and young children should avoid seafood with high mercury content and opt for fish low in mercury instead.
The safest seafood choice for sushi is fish that has been either frozen or cooked before eating. Freezing or cooking their meat kills worms and larvae that may be present, reducing the risk of infection. The United States Environmental Protection Agency recommends that pregnant women and young children avoid certain seafood with high mercury content, such as swordfish, shark, king mackerel, and tilefish, and instead consume fish low in mercury like salmon, tilapia, shrimp, pollock, and catfish.
Freezing or cooking seafood for sushi is important because it eliminates the risk of ingesting harmful worms and larvae that may be present in the meat. This helps to ensure food safety. Additionally, the accumulation of heavy metals like mercury and cadmium in certain seafood poses health risks, especially for pregnant women and young children. Choosing seafood with lower mercury content like salmon, tilapia, shrimp, pollock, and catfish is a safer option.
Overall, it is crucial to consider both the hygiene and health aspects when choosing safe seafood for sushi. Freezing or cooking ensures the elimination of potential parasites, while avoiding seafood with high mercury content reduces the consumption of harmful heavy metals.

B. There is too much competition from other fourth-level consumers, leaving very little available to the orange roughy.
C. Only a fraction of energy is passed through each level, so there is less available to upper-level consumers.
D. The energy flow is unbalanced and tends to move toward the lower levels.
The correct answer is option C
The fraction of energy that is available to the fourth level of the ecosystem is very less because the fraction of energy is passed on through each level.
According to the law, only 90% of the energy is transferred through each tropic level and rest of the energy is lost in the form of heat.
Thus, only a fraction of energy reaches the upper tropic level starting from the producers.
In the situation where Jeremy is digging in the garden and feels the spade hit a rock, the functioning of sensory, relay, and motor neurons is crucial in his body's response to this stimulus.
When Jeremy was digging in the garden, he felt the spade hit a rock. This is sensation was facilitated by sensory neurons which picked up the external stimulation and sent the information in the form of electrical impulses from the nerves in his hands towards his spinal cord and brain. This sensory information travels to the brain via relay neurons, which are also known as interneurons. They reside within the central nervous system and transmit the signals from sensory neurons to appropriate areas of the brain for processing.
Upon processing the sensory data, the brain forms a motor response which is relayed back towards the muscles in his arms to stop digging. The 'stop digging' response is sent through motor neurons, which transmit the signals from the brain to the muscles in Jeremy's arms, causing him to stop the movement of the spade.
