Given what we know about genetics, we can confirm that the case described in the question will be a result of a De Novo mutation.

A De Novo mutation is referred to as the most severe mutation type. This is a mutation that occurs even before embryonic development has commenced. They are usually the result of mutations in the DNA of the germ cells before being fertilized.

These mutations are responsible for a variety of disabilities and can target a wide array of genes to cause these effects.

List the cardiovascular and cardiac features unique to the fetus and describe their role in fetal circulation; explain the fate
STatiana [176]

Cardiovascular features unique to the Fetus:

Fetal circulation is characterized by low systemic vascular resistance (SVR) with high systemic blood flow and high pulmonary vascular resistance with low pulmonary blood flow.

<h3>What is fetal circulation?</h3>

The embryonic circulatory system directs blood that needs oxygen through three shunts, or microscopic tunnels. These shunts are intended to avoid forming organs like the liver and lungs while the fetus is still in the womb.

The foramen ovale, which carries blood from the right atrium of the heart to the left atrium, and the ductus arteriosus, which takes blood from the pulmonary artery to the aorta, are the two shunts that bypass the lungs.

Through the placenta, the mother's blood supplies the fetus with nutrition and oxygen. The enhanced blood divides into three branches as it travels via the umbilical cord to the liver.

Anestetic [448]

Blue-green algae affect freshwater, and it has a direct correlation to agricultural and urban runoff.

The heavy rains last spring most likely caused Lake Okeechobee to discharge water containing blue-green algae into rivers and canals. The bright green sludge oozed onto docks, dams and rivers and through tributaries into the ocean.

Blue-green algae (cyanobacteria) are a group of prokaryotic, autotrophic microorganisms that contain the photosynthetic pigments (chlorophyll and phycocyanin), Therefore, the DNA shows bacteria

Bacteria is the correct answer

Katyanochek1 [597]

Dr. Brantz wants to test the part of the brain which is active while lying. For this purpose, he will need to make use of the fMRI (functional magnetic resonance imaging) technique. This technique is used for measuring the brain activity by the means of the detecting changes in the blood flow. The neural activation affects the cerebral blood flow, and this change can be noticed using fMRI.

Hence, the answer is 'fMRI'.
