After school, Kai feels hungry and tired. He finds some sugar cookies in the cabinet and finishes the whole package.
Which statements best describe the role of glucagon and insulin in this scenario?
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin
was secreted after he ate the cookies because his blood glucose was high.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. Glucagon
was secreted after he ate the cookies because his blood glucose was high.
O Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he
ate, insulin from the cookies increased his blood sugar levels.
O Insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. After he ate,
glucagon from the cookies increased his blood sugar levels.
Answer: Option A) Glucagon was secreted by his pancreas before he ate the cookies because blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
Explanation:When Kai was hungry and his blood glucose level was decreasing, glucagon is the hormone which was secreted by the islets of pancreas to increase the blood sugar levels in his body. Glucagon forces the liver to release the stored glucose in it, which increases the blood glucose level in the body. When Kai ate the sugar cookies there was enough of blood glucose available for his body, also it exceeded the requirement and went high. Insulin was then secreted to control this excess glucose from the islets of pancreas. As it helps the body cells to absorb the glucose and lowers the amount of glucose in the blood. It makes the cell available with the glucose to produce energy and perform their activities.
In short, glucagon and insulin both are secreted by the same organ which is islets of pancreas. But they differ in their function, glucagon increases the blood glucose when the body needs it, whereas insulin helps to absorb the excessive glucose and stores that in the body. Both are the hormones which help in regulating the body glucose levels.
During process of digestion which takes place in digestive tract statement which describes role of glucagon and insulin is glucagon was secreted by pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate cookies because his blood glucose was high.
What is digestive tract?It consists of the gastrointestinal tract along with the accessory organs which are present in digestion process . It involves the breakdown of complex food into smaller components which can be easily assimilated and absorbed by the body.
The digestion process has 3 phases: cephalic phase , gastric phase and intestinal phase.Cephalic phase begins with secretion of gastric juices from gastric glands in response to sight and smell of food.It involves chewing and chemical breakdown of food by the action of digestive enzymes ,saliva in the mouth contain enzymes like lipase and amylase which are secreted by the salivary and serous glands present on the tongue.

If an element has 6 protons, 6 electrons, and 8 neurons, then what’s the atomic number
Answer:
The atomic mass is the number of protons, plus the number of neutrons. In this case, 8 + 6 = 14.
Explanation:
The six protons (atomic number) tells me that this is carbon; the six electrons tell me that this is a carbon atom, rather than a carbon ion (an ion is when the number of electrons does not equal the number of protons, making the atom electrically non-neutral). The eight neutrons tell me that this is an isotope (in other words, a version) of carbon called carbon-14, which happens to be mildly radioactive; and therefore useful to archaeologists in dating human artifacts.
The atomic number is the number of protons that is in the atom. If an element is having 6 protons, 6 electrons, and 8 neurons, then its atomic number will be 6, i.e. Carbon.
What is atomic number?Atomic number is the number of a chemical element as represented in a periodic system.
These elements are arranged in order of increasing number of protons in the nucleus.
The number of protons is always same as that of electrons in the neutral atom, which is also the atomic number.
Thus, here the number of protons given is 6 so the atomic number will be 6.

Two decades after the Emerald River Dam was built, none of the eight fish species native to the Emerald River was still reproducing adequately in the river below the dam. Since the dam reduced the annual range of water temperature in the river below the dam from 50 degrees to 6 degrees, scientists have hypothesized that sharply rising water temperatures must be involved in signaling the native species to begin the reproductive cycle.
Which of the following statements, if true, would most strengthen the scientists’ hypothesis?
(A) The native fish species were still able to reproduce only in side streams of the river below the dam where the annual temperature range remains approximately 50 degrees.
(B) Before the dam was built, the Emerald River annually overflowed its banks, creating backwaters that were critical breeding areas for the native species of fish.
(C) The lowest recorded temperature of the Emerald River before the dam was built was 34 degrees, whereas the lowest recorded temperature of the river after the dam was built has been 43 degrees.
(D) Nonnative species of fish, introduced into the Emerald River after the dam was built, have begun competing with the declining native fish species for food and space.

In a cladogram (a type of phylogenetic tree), clades are groups of related organisms. In the past, phylogenetic lists built clades using the idea of parsimony, that the pattern that uses the fewest evolutionary changes is the most likely to be correct. Today, with the use of computers and DNA sequences, the explanation that is thought to be the best is ___________ .
Answer:
one with the fewest number of genetic differences in the nucleotide sequence.
Explanation:
A cladogram is a diagram capable of showing the relationships among different species and/or group of organisms. In a cladogram, the root indicates the common ancestor, while internal nodes represent the common ancestors of each group. In consequence, this diagram can be used to establish evolutionary relationships in which the start branch points represent common ancestors shared by the organisms found in the 'branches'. Nonetheless, the length of the branches in the cladogram does not represent evolutionary distances among groups. In recent years, cladograms based on DNA sequencing data have been combined with morphological data to establish evolutionary relationships among species.

22. An astronaut on the space station tests whether gravity affects the productivity of tomato plants. What
is the independent variable in this experiment?
When conducting an experiment, the independent variable is always the one that produces or causes an effect or reaction on the dependent variable. In the exposed situation, the independent variable is gravity.
--------------------------------------
During an experiment, you need to consider all the variables involved.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified to analyze how another variable responds to it. The researcher changes the independent variable to observe its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, gravity is the independent variable, and influences the productivity of tomato plants. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.------------------------
