Explanation:
Wegener used evidence of climate change to support his hypothesis. As a continent moves toward the equator, its climate becomes warmer. As a continent moves toward the poles, its climate becomes colder. But the continent carries with it the fossils and rocks that formed at its previous locations.

Two differences between hormones and the nervous system
Answer:
Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
Explanation:
Answer:
the nervous system and endocrine system (hormones) is that the nervous system uses electrical impulses to send messages through neurons while endocrine glands use hormones to send messages to the target cells through the bloodstream.

How many valence electrons does carbon have? Is this atom satisfied? Explain.
Answer:
4 valence electrons
Explanation:
Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge.
Answer:
Carbon has 4 valence electrons. It is not satisfied. To be satisfied, it needs to covalently bond with 4 electrons to achieve octet (8 valence electrons).

When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis ____________ .
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy ____________ and oxidation of fat for energy ____________ .
Overall, when carbohydrate intake is excessive, lipogenesis ____________
Increase or decrease
Answer:
When carbohydrate consumption exceeds the body's immediate needs for energy, glycogenesis decreases.
The process of conversation of stored glycogen in the liver and muscles to glucose is Glycogenesis. It takes place when the blood glucose drops,below certain levels and the body cells need glucose for biochemical activities.Therefore, when there are excess CHO consumption,more glucose would be in the blood,and thus no need for glycogenesis.(breakdown of glycogen)
Glycogen storage space in the liver and muscles is limited. When glycogen stores are full, use of glucose for energy __Increases__________ and oxidation of fat for energy ___decreases_________ .
Definitely, this is a simple logic.As the storage for glycogen is limited,excess glucose move into the blood, since they can not be converted to glycogen.The glucose is expended through cellular reduce the amount in the blood. Therefore, Gluconeogenesis, the production of glucose from non-CHO substances drops. Hence beta- oxidation drops.
Overall, when carbohydrate intake is excessive, lipogenesis increases.The process of converting excess CHO to fatty acids.Biochemically it is the process of converting the Carbon precursor of acetyl co -A to fatty acids.Therefore this increases to synthesized more fatty acids from CHO

Plants have specialized structures that perform their necessary life functions. The gases that are crucial to proper
function within a plant are oxygen and carbon dioxide. What structure would control the exchange of these gases in
a plant?
a. mesophyll
b.trichomes
c.root hairs
d.stomata
Answer:
Stomata
Explanation:
Normally stomata open when the light strikes the leaf in the morning and close during the night.
d. During photosynthesis, CO2 enters the plant leave through opened stomata and in return it releases glucose,oxygen and some little molecules of water

Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above
Answer:
D
Explanation:
All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.
What are nonnative species?Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.
Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.
They are employed in restocking efforts, to replace native species, and for commercial purposes.
Thus, the correct option is D.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.
