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.

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

Why does DNA need to be extracted from a cell before it can be analyzed?
Answer:
to study the genetic causes of disease and for the development of diagnostics and drugs.
Explanation:
It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).
These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.
True or False - Statistical significance is commonly reported as odds ratios
(ORs), relative risks (RRS), or hazard ratios (HRs).
Answer:
The p-value is an estimate of whether the difference is a statistical accident or due to random chance. ... Epidemiological research usually uses different statistics to analyze their results. Epidemiological results are commonly reported as odds ratios (ORs), relative risks (RRs), or hazard ratios (HRs).

Identify the process in which the cell strives to maintain dynamic equilibrium:
homeostasis
turgor pressure
cytolysis
plasmolysis
Answer:
homeostasis
Explanation:
Homeostasis refers to the ability of the cell to keep a constant and stable environment. This includes chemical, physical, and biological components.
Cells need to regulate their environment despite the conditions outside of the cell. They need to be able to quickly adapt to changes to avoid harm to the cell.

Explanation:
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.

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.

Explanation:
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.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
S.A for Edmentum and Plato
Like and Rate
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

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.
