Which vein carries blood from the digestive organs to the liver?

Answer:

Competition is when you compete

Explanation:

We can justify using the disappearance of oxygen from the solution as a measure of electron transport due to the fact that oxygen is consumed during the process and is essential.

The electron transport chain is a complicated series of processes that take place within the mitochondria of a cell. This chain assists in the production of ATP which drives most of the functions of cells. The electron transport chain consists of various redox reactions between electron donors and receivers.

The role of oxygen in the electron transport chain is to act as the final receiver of electrons. Therefore, not only is oxygen consumed during this process, but it is also among the last steps, which allows us not only to measure that the electron transport chain had commenced, but also that it has proceeded correctly. We can do this based on the rate of disappearance of oxygen.

Answer:

False

Explanation: is correct

The double helix model of DNA explained Chargaff's rules because adenine and thymine are found in one strand of the double helix and guanine and cytosine are found in the other strand. Therefore, the correct option is C.

Since adenine (A) always associates with thymine (T) and guanine (G) always associates with cytosine (C), the double helix model of DNA provided an explanation for Chargaff's rules. This complimentary base pairing allows the two strands of the DNA double helix to fit together. According to Chargaff's criterion, DNA contains an equal number of A and T as well as G and C atoms.

The DNA molecule can be stabilized by hydrogen bonds formed between A–T and G–C base pairs, as shown by the double helix structure. Given that A and T are located in one strand of the double helix and G and C are found in the other, the double helix model of DNA provides a structural basis for understanding why Chargaff's rules are valid.

Therefore, the correct option is C.

Explanation:

Systemic circulation is a process through which oxygenated blood is pumped throughout the body of a living organism by the left-side of a mammalian heart.

Cardiac cycle can be defined as a complete heartbeat of the mammalian heart, which typically comprises sequential alternating contraction and relaxation of both the atria and ventricles, therefore causing oxygen-rich blood to flow unidirectionally (in one direction) throughout the human body.

Given what we know about embryological development, we can confirm that the option that is matched correctly with its trimester is the first trimester—tissues and organs form; amniotic sac forms; neurulation occurs.

The first trimester is one of the busiest for a fetus. During this trimester:

and so much more that is not mentioned in the question.

The formation of the amniotic sac is the earliest of the major events listed. This sac serves as the aquatic medium in which the fetus will find itself during the next 9 months.

Neurulation is the name given to a very complex set of processes that lead to the creation of the neural tube and then the brain. Then, finally, the tissues and organs finish forming into their embryonic stages.

Explanation:

oxygen is needed for respiration which provides energy for active transport of the ions into the plant.

active transport is needed to move the ions into the plant as there are higher levels of concentration already in the cell sap.

Hoagland found that some ions were absorbed only if oxygen was bubbled through the pond water needed for respiration for active transport.

Oxygen has been needed for respiration which provides energy for active transport of the ions into the plant and active transport has needed to move the ions into the plant as there are higher levels of concentration already in the cell sap.

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is in cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate).

Adenosine triphosphate has an organic compound which gives energy to living organisms to drive many operations in living cells. such as muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.

Therefore, Hoagland found that some ions were absorbed only if oxygen was bubbled through the pond water needed for respiration for active transport.

Supporting evidence came from paleontology: the fossils of some dinosaur and other reptile species, such as the freshwater swimming reptile the Mesosaurus, are found on both sides of the southern Atlantic Ocean, but nowhere else in the world. Also if you want there is evidence that climate change was also a part of the continental drift since Antarctica was connected with the rest of the continentes, since Antarctica has ice they melted and slowly moved apart. Behind all of this is plate tectonics since they are underneath all of this which helped move the continents. By convection currents how Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth’s crust, plates move apart. Where convection currents converge, plates move towards each other. But this is mostly with boundaries.

In 3–5 sentences the fossil evidence Wegener used to support the theories of continental drift and plate tectonics is described below

The continental drift hypothesis of whener was based on a number of observations and fossil records is one of them. Wegener found that fossils of a reptile named Mesosaurus can be found in Africa, South America despite vast distance between them by grand ocean of Atlantic.

Similarly fossils of a tree leaves called Glossopteris were found in India, Antarctica, Southern America and Africa. So the evidence suggested that in geological history all these land massed were connected and joined as one landmass.

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.

Hope that help

Explanation:

For the principle of Hardy Weinberg where the principle is saying that the genetic variations remain constant until any disturbing factors come up. The conditions are like no gene flow, natural selection and many more.

The theory of fittest says that the species that are able to adapt the variations and able to adapt to the changes that are  taking place in nature are selected by nature for the survival and are fit to live.

The conditions are necessary for hardy–Weinberg equilibrium, and conditions lead to evolution are as following :

The species should not have the mutations that the species should have the same copy of the genome with no change in the genome.  

Random mating that is the individuals that are selected by the nature or who randomly mate make no change in the nature.

The population size should be bigger that is the individuals should be bigger in size and the change thus is small in size.

No selection

No gene flow are the various conditions that need to be followed in order to maintain the equilibrium as per the law.
