how did wegner use climate evidence to support his hypothesis
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.

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

List the 2 Sources of Energy for Living Organisms.
Answer:
The Sun is a source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.
Whats the difference from the first and second law of thermodynamics
Answer:
Explanation:
the first law is the law of conservation of energy which basically means energy can't be created or destroyed in an isolated system.
the second law is that the entropy always increases in the isolated system. entropy is the measurement of the units thermal energy per unit temp.

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

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.

Are humans heterotrophs or autotrophs? Pleas Help Me.. Thx:)
Answer:
Heterotroph
Explanation:
They require other sources to sustain themselves and cannot produce their own energy.
Answer:
Heterotrophs
Explanation:
Producers are the most common type of autotrophs because they are able to make food out of energy and any other materials they happen to find or lie upon. Humans cannot create food from energy because they are not producers.
Heterotrophs are organisms that eat consumers or producers. A human can eat other consumers (meat/omnivore) and eat plants (producer) like lettuce or kale.

how do ferns reproduce?
Ferns produce male and female cones.
Ferns produce spores under its leaves.
Ferns produce egg and sperms cells in the leaves.
Ferns produce flowers that contain egg and sperm cells.
Answer:
The answer is C.
Explanation:
Most ferns reproduce differently, and that involves meiosis and fertilization. When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. The spores are released into the wind.
Answer: The correct answer on Ody2020 is: Ferns produce spores under its leaves.
Explanation: Got it right on the assignment.
