Answer:
true
Explanation:
7. Many athletes who are in good condition have heartbeat rates that are substantially slower than the 60 to 80 beats per minute (bpm) considered normal for the rest of us. Former cyclist Lance Armstrong routinely had a resting heart rate of about 32 bpm. For a non-athlete, a heartbeat rate this low might be cause for hospitalization, but the rate of blood flow in an athlete's body is not affected by it. How can an athlete's body function normally with such a low heartbeat rate? A. People who are athletes are born with slow heart rates so it is normal for them. B. Exercise strengthens the athlete's heart muscle so more blood is pumped with each beat. C. An athlete's heart rate is higher than normal while exercising so it averages out to normal. D. More capillaries appear in muscle tissue with exercise so blood flow is more efficient O * S
Exercise strengthens the athlete's heart muscle so more blood is pumped with each beat. The correct answer is B.
Athletes who train regularly and are in good physical condition have larger, stronger hearts than non-athletes. This allows their hearts to pump more blood with each beat, which means that their hearts don't have to beat as frequently to maintain a normal rate of blood flow. Additionally, athletes often have more efficient circulatory systems, with more capillaries in their muscles, allowing for more oxygen to be delivered to the tissues. These adaptations allow athletes to maintain a normal rate of blood flow even with a slower resting heart rate. While an athlete's heart rate may be higher than normal during exercise, their resting heart rate can be significantly lower due to the adaptations that come with training and physical conditioning.

What substance released from damaged endothelium triggers the extrinsic coagulation pathway?
The substance released from damaged endothelium that triggers the extrinsic coagulation pathway is tissue factor, also known as factor III.
Tissue factor is a protein that is found on the surface of cells in the blood vessels and is not normally exposed to the bloodstream. However, when there is damage to the blood vessel or surrounding tissue, is released and comes into contact with factor VII in the bloodstream. This contact activates factor VII, which then initiates the extrinsic pathway of the coagulation cascade.
The extrinsic pathway is one of the two pathways that lead to the activation of thrombin and the formation of a fibrin clot. The other pathway is the intrinsic pathway, which is initiated by factors that are present within the blood itself.

Find in the sequence where each primer binds. Draw a box around where each primer will bind. In this case, exactly how many base pairs do you expect your pcr product to be?
The size of the base pairs , the specificity of the primers, and the PCR reaction conditions can all affect the expected size of the PCR product.
In general, PCR primers are designed to bind to complementary sequences flanking the target region of interest.
To identify where the primers will bind, the sequence can be searched using online tools such as BLAST or Primer3, which can identify potential primer binding sites and design primers specific to the target region.
Once the primers have been designed and their binding sites determined, the expected size of the PCR product can be calculated by subtracting the position of the 5' end of the forward primer from the position of the 3' end of the reverse primer, minus any overlap between the primers. The expected size of the PCR product can vary depending on the size of the target region, the specificity of the primers, and the conditions used in the PCR reaction.

b. leave, stay
c. rise, sink
d. sink, rise
The Sun strikes the Earth the most at the Equator and the least at the poles. This causes warm air to rise from the equator and cold air to sink at the poles. Therefore, the correct answer is (c) rise, sink .
How earth rotates ?
The Earth rotates on its axis, an imaginary line that runs through the North and South Poles, once every 24 hours. This rotation gives rise to day and night and causes the stars, sun, and moon to appear to move across the sky. The Earth's rotation is caused by the initial angular momentum it received from the big bang and the conservation of angular momentum as it continues to rotate.
The direction of rotation is from west to east, which is known as prograde rotation. The speed of rotation is fastest at the equator and slower at the poles due to the Earth's shape and composition. The Earth's rotation plays a significant role in regulating the planet's climate and weather patterns, as well as influencing the behavior of ocean currents and other natural phenomena.
The Earth revolves around the Sun in an elliptical orbit, completing one revolution in 365.24 days, which is one year. This revolution is caused by the gravitational attraction between the Sun and Earth. As the Earth orbits the Sun, it also rotates on its axis, causing day and night. The changing distance between the Earth and Sun throughout the year affects the amount of solar energy that reaches the Earth, which in turn influences the planet's climate and weather patterns.

abscisic acid (aba) is synthesized in the roots in response to decreased soil water potential. aba then translocates to the leaves, where it rapidly alters the osmotic potential of guard cells. what effect would this have on the stomata and the process of transpiration?
Abscisic acid (aba) is synthesized in the roots in response to decreased soil water potential. ABA then translocates to the leaves, where it rapidly alters the osmotic potential of guard cells. The effect would this have on the stomata and the process of transpiration is: that it slows down transpiration by causing the stomata to close tightly.
Abscisic acid (ABA) is synthesized in roots as a response to decreased soil water potential. ABA translocates to leaves and immediately alters the osmotic potential of guard cells. Abscisic acid (ABA) has a considerable impact on stomata and the process of transpiration. Abscisic acid (ABA) is a hormone that regulates the stomata in plants.
ABA causes the stomata to shut down, reducing the transpiration rate of the plant. The hormone ABA acts on guard cells by altering their ion transfer patterns, resulting in stomatal closure. Transpiration is the process of water loss from plants due to transpiration, and ABA is involved in regulating the loss of water in plants.
ABA inhibits the opening of the stomata by lowering the water potential of the cells, causing them to close. ABA can also signal the cells to lower their water content, which aids in the cells' shrinking and allows the stomata to close more tightly.ABA plays a significant role in plants' growth and survival, especially during drought stress.
In summary, the impact of ABA on the stomata and the process of transpiration is that it slows down transpiration by causing the stomata to close tightly.

In order for an ovule (egg cell) in a flower to be fertilized and form a viable seed, pollination must occur. In this process, a sperm cell is delivered to the ovule when the pollen grain lands on the stigma and grows a tube, which enters the ovary and discharges the sperm cell to form a diploid zygote when it fuses with the egg cell. Although it only takes one pollen grain to successfully deliver sperm to the egg, numerous pollen grains are generally transferred to the stigma during insect pollination of flowering plants. Which phenotypic traits of pollen would you predict to be selected upon to promote survival and fitness within an insect-pollinated flowering plant?
The phenotypic traits of pollen that would likely be selected to promote survival and fitness within an insect-pollinated flowering plant include characteristics that make the pollen more attractive to the insects that will transfer it from one plant to another.
This may include traits such as size, shape, color, scent, and sugar content. For example, larger pollen grains may be easier for insects to collect and transfer, while a particular color or scent may be more attractive to a certain species of insect pollinator.
Additionally, pollen with a higher sugar content may be more attractive to insects as a food source, potentially increasing the likelihood of successful pollination. Overall, the traits that are selected will likely depend on the specific insects that are the primary pollinators for the plant species in question.
