The correct answer is option B, that is, they all use cellular respiration to obtain energy.
Cellular respiration refers to a set of metabolic procedures and reactions, which occur in the cells of species to transform biochemical energy into ATP and then discharge waste products. The reactions taking place in respiration are catabolic, that is, dissociation of bigger molecules into smaller ones, and in the process liberating energy.
The nutrients, which are generally utilized by plant and animal cells in the process of respiration are amino acids, sugar, and fatty acids, and the most usual oxidizing agent, that is, the electron acceptor is the molecular oxygen.
Answer:
When people have anemia, their body doesn't produce enough red blood cells. They don't get enough oxygen, which makes them feel fatigued and can also cause serious health complications.
Answer: Weather balloons are special balloons that have a weather pack on them that measures air pressure, temperature, wind speed
Explanation: Meteorologists are able to predict the changes in weather patterns by using several different tools And the weather ballon has that weather pack that measures air pressure temparature and wind speed and that can predict future weather conditions.
Answer: B and D

Answer:
Macrophages are part of your innate immune system, which is antigen-independent and does not require activation.
Explanation:
Macrophages phagocytize (internalize) all non-self pathogens it encounters. These do their job without activation. Other cells in the innate immune system include basophils, neutrophils, eosinophils (these cells are polymorphonuclear leukocytes), mast cells, and dendritic cells, which act as the bridge between your innate and adaptive immune system.
All of the other entities listed above are part of your adaptive immune system. The adaptive immune system is antigen-dependent and requires activation. This section of your immune system responds differently to different pathogens, and has the bonus of having immunologic memory, the ability to remember pathogens after infection and respond much quicker upon secondary and tertiary encounters.
Note: All lymphocyte types begin as naïve cells, which then differentiate into their fully matured form upon activation.
Helper T cells are a type of CD4+ T cell that has the job of activating B and T lymphocytes. There are two different types of T helper cells: Th1 and Th2. Th1 cells secrete the cytokine interferon-gamma (IFNγ), and is primarily involved with the stimulation and activation of cytotoxic T cells, while Th2 cells secrete a variety of cytokines and are responsible for activating and assisting with B cells to make antibodies. To make a long story short, Th cells interact with APC (Antigen Presenting Cells), specifically their Class II MHC (a group of genes that present exogenous proteins). The Th cells then proliferate and gain the ability to activate these APC cells and provide the necessary signals to activate B and T cells and make them proliferate and do their specific function.
