Blood is supplied to the muscular wall of the left atrium by the left coronary artery
Blood is considered a connective tissue that remains flowing continuously in the body and carries oxygen, nutrients, and hormones from one place to another place in the body.
It is pumped into the body equally through the heart which consists of four chambers and several valves and arteries which work in a coordinated manner to collect deoxygenated blood collected from the body and replace oxygen in it and pump it into the other parts of the body.
The left coronary artery (LCA), also known as the left main coronary artery (LMCA) arises from the aorta above the left cusp of the aortic valve and transports the blood to the left side of the heart muscle.

C.It regulates ion concentrations in the cells.
D.It regulates transport between cells.
The correct option is B. It regulates body temperature.
What is homeostasis?In biology, homeostasis is the condition of steady internal, physical, and chemical requirements maintained by living systems.
This is the requirement of optimal functioning for the organism and contains many variables, such as body temperature and fluid balance, being kept within certain pre-set limitations (homeostatic range). Other variables include the pH of extracellular fluid, the engagements of sodium, potassium, and calcium ions, as competently as the blood sugar level, and these need to be regulated despite changes in the atmosphere, diet, or level of activity. Each of these variables is controlled by one or better controllers or homeostatic mechanisms, which together maintain life.Homeostasis exist obtained about by a natural resistance to switch when already in the optimal conditions, and balance is maintained by many regulatory mechanisms. All homeostatic control mechanisms include at least three interdependent elements for the variable being regulated: a receptor, a control center, and an effector.To learn more about homeostasis, refer:

Natural selection is a type of selection that exists between certain inherited conditions and environmental pressures.
How does malaria and sickle cell anemia show natural selection?The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. Natural selection is a non-random difference in reproductive output among replicating entities.
It turns out that HbS carriers have been naturally chosen in these regions because the trait gives some malaria resistance. When they are infected with the malaria parasite, their red blood cells, which include some aberrant hemoglobin, have a propensity to sickle. The malaria life cycle intensifies both natural selection and random genetic drift.

How does ADP get recharged?
Adenosine triphosphate, or ATP, is the energy-carrying molecule used by cells because it has a rapid rate of energy release.
When the end phosphate is taken out, ATP releases energy. ADP (adenosine diphosphate), a low-energy molecule, is created when ATP releases energy.
These molecules can be recharged, ensuring that all of the cell's metabolic pathways have access to a steady stream of ATP that is high in energy.

During the alarm stage of the body’s stress response, what emergency hormone is released to prepare the body to respond to a stressor?.
The emergency hormone released is adrenaline.
What are the roles of the hormone adrenaline?Some of the neurons in the central nervous system and the medulla of the adrenal glands both create adrenaline. In a stressful circumstance, adrenaline is immediately released into the blood, sending signals to the organs to trigger a certain response, within a few minutes.
Depending on the sort of cells it is working upon, adrenaline has a wide range of diverse effects. However, adrenaline's general impact is to get the body ready for the "fight or flight" reaction under stress, that is, for quick and/or forceful action.
Key effects of adrenaline include speeding up heartbeat, raising blood pressure, widening the pupil of the eye, lessening pain sensitivity, improving vision, hearing, and other senses, slowing digestion, rerouting blood to the muscles, and changing the body's metabolism to maximize oxygen and nutrients to the body and raise blood glucose levels.

In addition to their distinctive subsistence strategies, horticulturalists are characterized by a large population and land ownership.
What are subsistence strategies?A subsistence pattern often called a subsistence strategy, is the way a civilization meets its fundamental necessities for survival. This includes having access to food, water, and shelter. Foraging, horticulture, pastoralism, agriculture, and industrial food production are the five basic groups of subsistence patterns.
The earliest kind of subsistence is foraging, which was the mainstay of all human cultures up until about 10,000 years ago. Horticultural societies often use basic tools for small-scale gardening. Higher population densities are possible using these strategies, but they still rely on the availability of lots of undeveloped lands.

What evidence suggests that proteins are synthesized and modified in the rough er as opposed to the smooth er?
The presence of ribosomes on the rough ER suggests that the proteins are synthesized as well as modified there as opposed to the smooth ER.
Ribosomes are responsible for the synthesis of proteins from the amino acids. They translate each codon on the RNA template and match it with the appropriate amino acid to make a protein. This process is known as translation. Ribosomes can be found free in the cytosol or attached to the surface of the endoplasmic reticulum. When the ribosomes are bound to it, it is known as the rough ER and without it, it is called smooth ER. Smooth ER performs different functions like the synthesis of lipids and phospholipids.

Bladder cancer (BCa) is an endocrine-related tumor and the activation of androgen signaling pathways may promote bladder tumorigenesis.
Abstract:We compiled the research on the effects of altering androgen signaling pathways on Bladder cancer therapy outcomes, both preclinical and clinical. A thorough analysis was done in December 2020. The following criteria were met by the papers we included: examining the effects of androgen signaling regulation on the results of Bladder cancer treatments through innovative preclinical and clinical studies. Eight clinical trials and six preclinical studies were found. Preclinical research shows that the activity of radiation, doxorubicin, cisplatin, gemcitabine, and the Bacillus Calmette Guerin may be affected by the modification of androgen receptor-related pathways.
Patients receiving treatment with 5-ARIs or androgen deprivation therapy (ADT) have a considerably lower relative risk of developing Bladder cancer again after transurethral resection of the bladder tumor (TURBT) (Relative risk: 0.50, 95 percent confidence interval: 0.30-0.82; p = 0.006). In patients using 5-ARIs, subgroup analysis showed a relative risk of BCa recurrence of 0.46 (95% CI: 0.22-0.95; p = 0.040). The ratio of T1 Bladder cancer patients in treated/control groups and the relative risk of BCa recurrence were found to be significantly negatively correlated. A promising technique to lower the recurrence rate of Bladder cancer, particularly in patients with early-stage disease, may involve 5-ARI therapy. To corroborate these early findings, additional research is required.
