A genetically engineered corn plant is approved for agricultural use. The plant produces pollen that can make its own toxins. Th

ese toxins protect the corn plant against pests. What is a likely impact on the farmer of growing such a variety of corn?
The financial costs for the farmer would be lowered.

Federal agencies could initiate legal action against the farmer.

The farmer may be held responsible for increasing chemical pollution.

The farmer's expenses for pest control would increase due to an increase in bee population.

Answer: The financial costs for the farmer would be lowered.

Explanation:

According to the given situation, the genetically grown corn is capable of producing the pollen which consists of toxins. These toxins will kill the pests. Therefore, it reduces the cost of pesticides. Hence, the overall financial costs for the farmer would be lowered.

Why did proteins seem better suited for storing genetic information?
alexgriva [62]

Answer:

Proteins seem better suited for storing genetic information because DNA is only made from 4 bases while proteins were made from 20 amino acids, Scientists thought that proteins could code for much greater variety in their amino acid sequence than DNA could in its nucleotide sequence.

View the animation below, then complete the quiz to test your knowledge of the concept. conducting of the heart
valina [46]
1. In the heart, an action potential originates in the (E) sinoatrial node.
The cardiac action potential is a term referring to the change in the membrane potential of heart cells causing the heart to contract. Cardiac action potentials are created by a group of specialized cells capable of generating automatic action potentials and are located in the right atrium of the heart. These cells are called sinoatrial node and sometimes are referred to as the natural pacemaker of the heart. This characterization originates from the fact that sinoatrial node continuously provides action potential and sets the rhythm of the heart function.

2. The sequence of travel by an action potential through the heart is (A) sinoatrial node, atrioventricular node, atrioventricular bundle, bundle branches, Purkinje fibers.
As explained above, the cardiac action potential originates from the sinoatrial node. This action potential then travels through the atrioventricular node, which belongs to the electrical conduction system of the heart and is located between the atria and the ventricles. It is responsible for the electrical connection between the right atrium and the right ventricle. The action potential then travels to the atrioventricular bundle (or bundle of His), another part of the electrical conduction system of the heart. The atrioventricular bundle transmits the electrical impulses from the atrioventricular node to the bundle branches. The bundle branches then send the signal to the Purkinje fibers which send the electrical impulses to the ventricles, causing them to contract. 

3. The correct answer is A.
The generation of an action potential in the sinoatrial node causes the contraction of the atria. When the action potential passes from the sinoatrial node to the atrioventricular node, it slows down. This causes the transport of the electrical impulse from the atria to the ventricles to slow down. This delay enables the blood (from the contraction of the atria) to fill the ventricles before their contraction. 

4. This statement is true.
The interventricular septum is a structure which divides the two ventricles of the heart and it is composed of two branches, the left bundle and the right bundle branch. When the action potential reaches the interventricular septum, it then travels to the apex of the heart from where it travels upwards along the walls of the ventricles and the ventricular contraction begins.

5. This statement is true.  
The bundle branches gradually become Purkinje fibers located in the interior of the ventricular walls. Purkinje fibers are specialized cells and are responsible for conducting cardiac action potentials from the bundle branches to the ventricular walls. This signal transduction causes the muscle of the ventricular walls to contract.

Blue whales have 44 chromosomes in every cell. determine how many chromosomes you would expect to find in the following:Sperm ce
baherus [9]

Sperm cell: We expect to find 22 chromosomes.

The spermatozoon is a small cell (5 micrometers in diameter), much smaller than the ovum, but with a movable tail (a flagellum) 60 micrometers long. To be lightweight and mobile, to quickly reach the egg, the sperm gains space by minimizing its cytoplasm and compacting its DNA. Head is covered with the acrosome, a pocket full of enzymes that will be used to pierce the membrane of the egg.

It is a haploid cell because it contains half of the genetic material of the individual, lost at the time of meiosis during the process of spermatogenesis that the primordial germ cells undergo in the seminiferous tubules of the testes.


Egg Cell: We expect to find 22 chromosomes.

The egg is the sexual cell (or gamete) produced by the females of the animals.

Like all gametes, the egg is haploid, it contains half of the chromosomes of the future embryo, so the number of chromosomes will be 22 instead of 44. Then this egg will meet a sperm cell to gather their chromosome and form an embryo of 44 chromosomes.


Daughter Cell from Mitosis: We expect to find 44 chromosomes.

Mitosis, which ensures the birth of cells identical to the mother cell during asexual multiplication (so the number of chromosomes will remain the same, it will not divide in two).

Mitosis is an asexual cell division. This means that it is just a division of a mother cell into two daughter cells, which will inherit exactly the same genetic inheritance.


Daughter Cell from Meiosis II: We expect to find 22 chromosomes.

Meiosis is a particular mode of division of the living cell by which an initial cell with 2n chromosomes (in this case 2n = 44 chromosomes), a diploid stage, gives rise to four daughter cells possessing only n chromosomes, a haploid stage (n = 22 chromosomes). Meiosis is one of the forms of cell reproduction, this process is performed on the gonads to produce gametes.
