Answer:
A.) Low-pressure systems are usually associated with clouds and precipitation that minimize temperature changes throughout the day
B.) The slightly inward moving air in low pressure causes air to converge and since it can’t move downward because of the surface, the air is forced upward, leading to condensation and precipitation
Explanation:
Why is human blood red and not blue such as squid & snail blood?
Hemoglobin contains copper that gives the blood the red color when exposed to
oxygen
Hemoglobin contains magnesium that gives the blood the red color when
exposed to oxygen
Hemoglobin contains iron that gives the blood the red color when exposed to
oxygen
Answer:
it contains iron that gives it the red color when exposed to oxygen
Human blood-red and not blue because Hemoglobin contains iron that gives the blood the red color when exposed to oxygen. The correct option is c.
What is hemoglobin?Hemoglobin is a red color pigment that is present in the blood. It contains a heme group that carries oxygen into the body and carries carbon dioxide outside the blood. It is red and in some animals, it is blue because of copper.
Hemoglobin is made up of four protein chains that each bind an additional ring-shaped chemical structure called heme. Our red blood cells are red because of the heme groups in hemoglobin. In turn, our blood is red because of the millions of red blood cells that it contains.
Therefore, the correct option is c. Hemoglobin contains iron that gives the blood a red color when exposed to oxygen.

Answer:
1.Toad
2.Newt
3.Salamander
In addition to the frog, the other organisms that are classified as modern amphibians are toads and salamanders. Therefore, the correct option is A.
What are modern amphibians?Modern amphibians are a class of cold-blooded vertebrates that spend part of their life cycle in water and part on land. They are united under the taxon Lissamphibia. They are divided into three clades which are Urodela, Anura and Apoda. In addition to frogs, the other two groups of modern amphibians are toads and salamanders.
Snakes and lizards are reptiles, which are a different class of cold-blooded vertebrates. Opossums and koalas are marsupials, which are warm-blooded mammals, and sharks and skates are fish, which are cold-blooded vertebrates but are not classified as amphibians. Therefore, the correct option is A.

In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
Answer:
All will have both red and white flowers because the incomplete dominance have two combined alleles given for the offspring with intermediate phenotypes. Then offspring will be pink coloured while in codominance all alleles are expressed in phenotype in the offspring together so the red and white flowers both will be shown.

1. Two plant species grow together in an oak savanna. One is fairly long-lived and produces few large seeds. The other is short-lived and produces many small seeds. a. What are the ecological advantages and disadvantages of each
Answer:
d
took the test
Explanation:
Large seeds advantages:
They have a higher chance of germination and thriving.Large seeds disadvantages:
They can not easily spread to new areas.Small seed advantages:
They can spread easier to new areas.Small Seed disadvantages:
They have a lower chance of surviving.
Large and small seeds main difference resides in their structure. The structure allows them to survive or to cover new areas. The disadvantage is that it can only do one of the two things.
Large seeds, as they are larger:
They have a structure that allows them to store more energy than small seeds. As a consequence, they have more elements to thrive and grow into a plant than small ones.Due to their size, they are heavier. They do not spread as far as the others.Small seeds :
They do not have enough energy to grow, so they need more aid from the environment than large ones. In other words, their chances of survival are lower.The advantage is that they can colonize wide areas due to their lightness. So, even though they are small, they spread easier and cover more territory than large seeds.
To sum up, small seeds have a lower chance of survival, but they are more and cover longer distances. While large ones have a higher chance of survival, but they are fewer and cover short distances.

compared to parasympathetic ganglia, sympathetic ganglia are __________.
Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.
In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

A.Only in the dark in plants
B.In the light and dark in plants
C.Only in the light in plants
D.None of the above
Answer:
Your answer wold be B: In the light and dark in plants
Explanation:
In the light and dark in plants is the correct answer
The option (B) is correct. In the light and dark in plants.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Moreover, photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Hence, the primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process. It's not particularly efficient by human engineering standards, but it does the job.

The results suggest the optimum temperature for the enzyme is between which two values?
A 15 °C and 35 °C B
35 °C and 45 °C C
35 °C and 55 °C D
45 °C and 55°C
Answer:D
Explanation:
The optimum temperature for the enzyme is between 45 °C and 55°C. Therefore, option (D) is correct.
What is an optimum temperature for enzyme?Most enzymes perform best at a temperature of around 98.6 degrees Fahrenheit (37 degrees Celsius). Additionally, some enzymes function well both at low and high temperatures. For instance, while animals in desert climates have enzymes adapted to higher temperatures, those in the Arctic have them adapted to lower optimal temperatures.
The reaction rate will accelerate as more hydrogen peroxide is added to the mixture because more substrate molecules can interact with the enzyme and produce more product as a result. As you increase the amount of H2O2 in your reaction, more foam is generated in your cup as a result.
