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.

Hydrocephalus

An excessive buildup of cerebrospinal fluid (CSF), the clear fluid that surrounds the brain and spinal cord, is the main symptom of the illness known as hydrocephalus. The ventricles in the brain, which are empty areas, enlarge abnormally as a result of this excessive accumulation. Pressure on the brain's tissues as a result of this dilatation could be detrimental. Both congenital and acquired hydrocephalus are possible.

The surgical installation of a shunt device is the most common treatment for hydrocephalus. With the help of this system, CSF (cerebrospinal fluid) is switched from one location in the central nervous system to another one where it can be absorbed as part of the circulatory system. A different method known as third ventriculostomy can be used to treat a small number of patients. The third ventricle's floor is punctured during this surgery to allow the CSF to pass through the blockage and move toward the area of resorption near the brain's surface.

According to this mechanism, organisms that are better skilled of adapting to their changing environmental conditions, survive and grow their number through reproduction whereas other are stopped from the population.

The theory of natural selection was studied by 19th-century naturalist Charles Darwin. Natural selection describes how genetic traits of a species may change over time.

Natural selection is the process in nature by which organisms better adapted to their environment manage to persist and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes consumed by snakes and birds.

Arrangement of transport choices if begin with the person with the smallest carbon footprint is Lance < Kesha < Soha .

The entire amount of greenhouse gases (such as carbon dioxide and methane) produced by human actions is known as a carbon footprint.

Let's first take the example of Lance who rides a bicycle to their workplace.

The amount of carbon emission in riding a bicycle is comparatively very low in comparison to the hybrid electric car and gasoline-powered sedan as the bicycle doesn't emit any fumes.

Cycling emits 84 percent less CO2 on average than driving a car or using public transportation.

So, Lance is the person with the smallest carbon footprint.

Now if we compare Kesha with hybrid electric car and Soha with gasoline-powered Sedan, Kesha will have smaller carbon footprint.

In general, compared to conventional vehicles like gasoline-powered sedan, all-electric, plug-in hybrid electric, and hybrid electric vehicles (HEVs) have reduced exhaust emissions like carbon-di-oxide.

So, the correct arrangement of transport choices if begin with the person with the smallest carbon footprint is Lance < Kesha < Soha.

A group of proteins in the thylakoid membrane that shuttles electrons between the proteins and other carriers is called an Electron transport chain.

In photosynthetic eukaryotes, the electron transport chain is observed on the thylakoid membrane. here, light energy drives electron transport through a proton pump and the ensuing proton gradient causes the next synthesis of ATP.

The light reactions are finished by means of the thylakoid membrane protein complexes photosystem II (PSII), cytochrome b6/f complicated, photosystem I (PSI), and ATP synthase. Many proteins that play crucial capabilities in both reactions have poor roles in viral pathogenesis.

The most outstanding thylakoid transporter is the proton-translocating ATP-synthase.

If the heterozygous phenotype is intermediate between that of the homozygotes this is called independent dominance. The correct answer is B. incomplete dominance.

Incomplete dominance refers to the phenomenon in which two true-breeding parents interbred to create an intermediate child (sometimes referred to as heterozygous). Alternate names for it include partial dominance and intermediate inheritance. In the case of partial dominance, the variations (alleles) are expressed in a reduced ratio rather than as dominant or recessive.

A new heterozygous phenotype is produced by imperfect dominance, often known as the dilution of the dominant allele relative to the recessive allele. For instance

Star formation begins with the collapse of molecular clouds and fragmentation into highly dense masses. These masses initially contain about 0.01 solar masses, but increase in mass as the surrounding matter is collected by accretion.
