Answer:
The correct answer is - cellular respiration.
Explanation:
Bread rising is due to the production of carbon dioxide by yeast in both aerobic and anaerobic cellular respiration. If there is a presence of oxygen, yeast performs aerobic respiration and produce carbon dioxide from sugar or other sources of carbohydrates.
In absence of oxygen, yeast performs anaerobic respiration or undergo fermentation to produce carbon dioxide and alcohol as waste products.
Thus, the correct answer is - cellular respiration.

Haemophilia is a genetic condition that impairs people's ability to form blood clots. Some forms of it are known to be sex-linked. Suppose that equal proportions of people are men and women, ignoring further gender variance. One meta-study estimates that 2-in-10,000 men and 1-in-100,000 women have a particular sex-linked form of haemophilia. (a) What is the probability that a randomly chosen person has haemophilia? (b) What is the probability that a given person with haemophilia is a man?
(a) The probability of a randomly chosen person having hemophilia is 0.000105.
(b) The probability that a given person with hemophilia is male is approximately 1.9.
(a) Probability that a randomly chosen person has hemophilia:
Haemophilia can affect both males and females, but we need to find the probability for both. Hence,
the probability of having hemophilia = probability that a randomly chosen person is male × probability that a male has hemophilia + probability that a randomly chosen person is female × probability that a female has hemophilia
Probability of having hemophilia in males = 2/10,000 = 0.0002
Probability of having hemophilia in females = 1/100,000 = 0.00001
Probability of a randomly chosen person is male = 0.5
Probability of a randomly chosen person is female = 0.5
Probability of having hemophilia = 0.5 × 0.0002 + 0.5 × 0.00001 = 0.000105
(b) Probability that a given person with haemophilia is a man:
From (a), we know that the probability of having hemophilia is 0.000105. Therefore, the probability that a given person with hemophilia is male is:
probability that a given person with haemophilia is a man = probability that a male has hemophilia/ probability of having hemophilia = 0.0002/0.000105 = 1.9048≈1.9 (approximately).

Place the characteristics of viral life cycles into the appropriate life cycle category.
Lytic Cycle
Lysogenic Cycle
- Contains a prophage
- Occurs in temperate viruses
- Replicated by cell division
- Has an assembly step
- are all virulent
- replicated by viral assembly
- viral genome active
- Viral genome repressed
Lytic Cycle: Replicated by cell division, Has an assembly step, Are all virulent, Replicated by viral assembly and Viral genome active.
Lysogenic Cycle: Contains a prophage, Occurs in temperate viruses and Viral genome repressed.
In the lytic cycle, the viral genome becomes active and directs the host cell's machinery to produce new viral components. The newly formed viral components are then assembled, leading to the lysis of the host cell and the release of new viral particles. This cycle is characteristic of virulent viruses, which immediately cause cell lysis.
In contrast, the lysogenic cycle involves the integration of the viral genome into the host cell's genome, forming a prophage. The viral genome remains repressed and is replicated along with the host genome during cell division. Temperate viruses exhibit the lysogenic cycle, where they can remain in a dormant state within the host cell for an extended period before transitioning into the lytic cycle.

Small living beings that live in the heart
Answer:
Small living beings that live in the heart are usually referred to as endocardial parasites or endocarditis-causing organisms. Endocarditis is the inflammation of the endocardium, which is the inner lining of the heart chambers and heart valves. It can be caused by various microorganisms, including bacteria, fungi, and in rare cases, parasites.
However, it's important to note that parasites living in the heart are relatively uncommon compared to other types of microorganisms. The majority of cases of endocarditis are caused by bacterial infections. Bacteria such as Streptococcus, Staphylococcus, and Enterococcus are commonly associated with endocarditis.
Parasitic infections that can affect the heart include certain species of worms, such as the dog heartworm (Dirofilarial imcites) and the human parasite called Echinococcal. These parasites typically do not directly inhabit the heart itself but can affect the heart and its surrounding structures.
It's essential to consult with a healthcare professional if you suspect any cardiac-related infections or diseases to receive an accurate diagnosis and appropriate treatment.

Neurotransmitters are released from axon terminals via _______. A. osmosis B. active transport C. diffusion D. exocytosis
The correct option is D
Neurotransmitters are released from axon terminals via exocytosis.
A neurotransmitter is stored inside synaptic vesicles which is a small sac-like structure. It is released into the synaptic cleft from axon terminals when a cell membrane fuses with vesicles. This process is termed exocytosis with the capability to release neurotransmitters in less than a millisecond.
In neurons of the nervous system, synaptic vesicle exocytosis occurs. Nerve cells communicate by electrical or chemical signals called neurotransmitters which are passed from one neuron to the next one. This transmission of neurotransmitters occurs by exocytosis.
The fundamental biological events of neurotransmission are dependent on neuronal communication and brain function including exocytosis of presynaptic vesicles which is for the release of neurotransmitters and the subsequent endocytosis.

16. a runner is running the 60-meter dash, which is an oxygen-deficient race. what type of energy is the runner's body using to power through the race?
During an oxygen-deficient race like the 60-meter dash, the runner's body primarily relies on anaerobic energy sources to power through the race. Specifically, the energy production occurs through anaerobic glycolysis.
Anaerobic glycolysis involves the breakdown of glucose in the absence of oxygen to produce energy. In this process, glucose is converted into pyruvate, which is then further metabolized to produce ATP (adenosine triphosphate), the energy currency of the cells. However, since there is insufficient oxygen available, pyruvate cannot enter the aerobic energy production pathway, such as the Krebs cycle and oxidative phosphorylation, where oxygen is required.
Instead, pyruvate is converted into lactate (lactic acid) through a process called lactate fermentation. This enables the continued production of ATP, but at a lower efficiency compared to aerobic respiration. Lactate can accumulate in the muscles, causing fatigue and discomfort during intense exercise.
