I believe the correct answer is FALSE.

<h2>Explanation:</h2>

The heart is an organ located at the center of the chest in the thoracic cavity and functions to supply blood to and from tissues giving the tissues oxygen and nutrients while taking away carbon dioxide and waste products. It is divided into 4 chambers and 2 chambers are separated by a muscular wall that prevents mixing of the blood.

<h2>Further Explanation:</h2>

Blood enters the heart via the vena cava which is divided into the superior vena cava that recieves blood from the upper region of the body that includes the head, neck and chest while the inferior vena cava recieves blood from the lower extremeties that includes the legs, the abdomen, the pelvic region and the thighs. The blood is deposited into the right atrium and is de-oxygenated. When it is deposited into the right atrium, the change in volume of the atrium and the expansion causes the valve to open and allow the de-oxygenated blood to flow into the right ventricle. The right ventricle then pumps the blood that is de-oxygenated to the lungs via the pulmonary artery which is the only artery that pumps de-oxygenated blood. In the lungs, carbon dioxide is removed and oxygen added to the blood and is taken to the left atrium which pumps the oxygenated blood to the left ventricle and then the left ventricle pumps the oxygenated blood to the rest of the body. The blood is then again taken through the body via the capillaries and the veins pick up the blood that has been removed of oxygen and added with carbon dioxide and transport the blood back to the heart via the vena cava. It enters the right atrium via both the inferior and superior vena cava and the de-oxygenated blood is circulated again to the lungs for oxygenation from the left ventricle.

The statement “the right ventricle transports oxygenated blood to lungs” is false.

Further Explanation:

Heart of humans have four chamber namely right and left atrium also, right and left ventricle. The main purpose of heart is to pump blood throughout the body. Due to this constant beating of heart a pressure is maintained in the body which helps in the flow of the blood.

The heart receives the deoxygenated blood from the body parts. This blood reaches the right atrium by means of superior and inferior vena cava. The blood from right atrium is pushed to the right ventricle. So, the right ventricle always has deoxygenated blood. This blood is then pushed to the lungs by the means of pulmonary artery into the lungs.

This blood then gets oxygenated by the means of fusion through capillaries and returns back to the heart specifically, to the left side. This blood is then pumped to the organ systems where it provides the tissues with oxygen.

<u>Important note- </u>

a. The right side of the heart always has deoxygenated blood.

b. The left side of the heart has oxygenated blood.

Therefore, the statement that the right ventricle of the heart has oxygenated blood is not true.

12. A plant has a dominant phenotype but an unknown genotype. The proper experiment to determine its correct genotype would be a

jekas [21]

Answer:

the correct answers are as follows

12:

b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.

13.

e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.

14.

c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.

e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.

Distinguish between directional, stabilizing, and disruptive selection. Give examples.

Pepsi [2]

Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.

Evidence suggests that first, ____________ were acquired when an aerobic bacterium was engulfed by larger cells and became mutua

leonid [27]

Answer:

1. Mitochondria

2. Chloroplast

3. the formation of eukaryotic cells

4. DNA

Explanation:

The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.

The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.

The evidence which supports their ar:

1. The same size of the organelles to the bacteria

2. The presence of the circular DNA of the organelles like bacteria

3. The similarity in the 30s and 70s ribosomal subunits.
