During isovolumetric phases of the cardiac cycle, a. The atria are contracting and all heart valves are closed. b. All heart valves are closed. c. The ventricles can only be relaxing. d. The atria are contracting. e. Blood is being ejected into the aorta.
During isovolumetric phases of the cardiac cycle, the atria are contracting.
What happen in isovolumetric phases of the cardiac cycle?The isovolumetric contraction occurs in isovolumetric phase that causes left ventricular pressure to rise above atrial pressure. This leads to opening of aortic valve at the end of isovolumetric contraction when left ventricular pressure exceeds aortic pressure.
So we can conclude that during isovolumetric phases of the cardiac cycle, the atria are contracting.

What is Herbicide?Herbicide may be defined as a chemical agent that is responsible for destroying or inhibiting the growth of a particular plant as compared to the normal one.
The projection is necessary because it supports the product after a one-year duration. So for example, if after one year there is undoubtedly a reduction in the intermediate height of the tomato plants, then we can absolutely say that it is because of the existence of NoGro herbicide which is supplied in water.
Therefore, it is well described above.

Discuss the relationship between the digestive systems a carnivore and herbivore and compare the length of the digestive system and diet of that animal
Herbivores have longer digestive systems than carnivores have.
How the herbivores have longer digestive systems compared to carnivores?We can conclude that the herbivores have longer digestive systems compared to carnivores.
Carnivores feeds on other animals whereas herbivores eats plants.Most herbivores have a four stomach compartment system that helps them process and digest their food.This is because they have to process cellulose in plants which needs to be properly broken down.Flesh-eating carnivores do not require this arrangement.The four stomach compartment of most herbivores includes Rumen, Reticulum, omasum and abomasum.They also chew the cud whereby they regurgitate food materials.Thus, this could be the answer.

The North Atlantic right whale was classified as an endangered species in 2015. A major cause of death for these whales is collisions with shipping vessels. Several measures have been enacted to prevent such collisions in regions with a high abundance of right whales. In 2002 and 2006, shipping vessel lanes were rerouted around some of these regions. In 2008, speed restrictions were placed on the shipping vessels that were permitted to travel through these regions.
The graph below shows the estimated abundance of North Atlantic right whales from 1990 to 2015. The years in which these measures were enacted are marked on the graph.
The data in the graph is best supported by : ( D ) While changes to vessel lanes and speeds may have been beneficial to right whales, additional actions are needed to prevent population declines.
Description from the GraphFrom the data presented in the graph the population of the right whales was favored by the changes in vessels lanes but the population began to decline again in and around 2009 therefore this is evident that additional actions are needed to prevent population declines other than changing vessel routes and placement of speed restrictions.

A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic to the cell, and one solution is hypertonic to the cell. Determine which type of solution is in each beaker based on the cell's reaction. Drag each item to the appropriate bin.
The type of solution in each beaker based on cell's reaction are :
Isotonic solution : Normal reactionHypotonic solution : The cell becomes turgidHypertonic solution : The cell becomes deformedMatching each solution to the cell reaction
When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.
