Alfred Wegener used rock and fossil evidence to support his hypothesis of continental movement by finding similarities in continent shapes, fossils, mountain ranges, and paleoclimate.
Explanation:Alfred Wegener used rock and fossil evidence to support his hypothesis of continental movement in several ways:
The continents looked like they fit together like pieces of a puzzle.There were matching fossils found on continents that were separated by oceans.There were matching mountain ranges on continents that were separated by oceans.There was paleoclimate evidence suggesting that in the past, some continents were closer to the polar regions and some were closer to the equator.With this evidence, Wegener proposed that all continents were once together in a single supercontinent called Pangea.

If the sequence in the coding strand of dna for a particular amino acid is 5'agt3', then the anticodon on the corresponding trna would be ________.
The anticodon on the corresponding tRNA would be 5'uga3'.This anticodon binds to the codon on the mRNA during protein synthesis.
Explanation:The coding strand of DNA is the strand that is used as a template to make the mRNA molecule.
In the coding strand, the sequence 5'agt3' corresponds to the sequence 3'tca5' in the template strand.
The anticodon on the tRNA molecule that pairs with the codon 3'tca5' is 5'uga3'.
This anticodon binds to the codon on the mRNA during protein synthesis.
A fine-grained soil deposited by wind is called _________, while a large region of sand is called a(n) _________.
A. erg; loess
B. loess; erg
C. desert; lichen
D. lichen; desert
Answer: B. loess; erg
Explanation:
Loess is a a type of soil which exhibit fine grained silt sized particles. It is formed by the accumulation of the wind blown dust. The 10% of the total land of earth is occupied by this type of soil. It consists of about 20-50 micrometer sized particles, 20% of the clay and balanced parts of sand and silts.
The erg can be define as the broad flat area of the desert which is occupied with the sandy soil. It exhibit little or no vegetation cover. The world largest erg is Sahara desert (African continent).

Which type of movement occurs in the intercarpal joint in the wrist? which type of movement occurs in the intercarpal joint in the wrist? opposition rotation gliding abduction/adduction?
The answer is gliding movement. The intercarpal joints are the articulations in the middle of the individual carpal bones. They are also known as plane synovial joints. This is one example of a gliding joint. These allow the bones to glide past one another in any course along the plane of the joint – up and down, left and right, and crosswise.
The movement that occurs in the intercarpal joint in the wrist is known as a gliding movement, allowing bones to slide over each other with little rotation. The correct option is: gliding
Type of Movement in the Intercarpal Joint in the Wrist
The movement that occurs in the intercarpal joint in the wrist is primarily a gliding movement. This type of movement is characterized by relatively flat bone surfaces sliding past each other, allowing for very little rotation or angular movement. Specifically, in the intercarpal joint, these gliding movements permit the bones to move slightly over one another, facilitating the complex motions necessary for the wrist's diverse range of activities.
Gliding joints, like those found in the wrist, enable the bones to flex and make small side-to-side motions. This action is essential for the fine motor skills required for tasks such as typing or playing a musical instrument.
Which of these hydrocarbons has a double bond in its carbon skeleton?
a. C3H8
b. C2H6
c. CH4
d. C2H4
(I don't know how to find out if their is a double bond based on the molecular formula)
Option d (C2H4) is the hydrocarbon that has a double bond in its carbon skeleton.
Explanation:In order to determine if a hydrocarbon has a double bond in its carbon skeleton, we can analyze its molecular formula. A hydrocarbon with a double bond will have the general formula CnH2n. In this case, the options are:
a. C3H8 - This does not follow the general formula for a hydrocarbon with a double bond.b. C2H6 - This does not follow the general formula for a hydrocarbon with a double bond.c. CH4 - This does not follow the general formula for a hydrocarbon with a double bond.d. C2H4 - This follows the general formula CnH2n and therefore has a double bond in its carbon skeleton.Based on the analysis, option d (C2H4) is the hydrocarbon that has a double bond in its carbon skeleton.

Tascha is on a medication that increases the pH of the stomach and makes it alkaline. What is the effect of this medication?
The medication hampers bile production.
Pepsin is unable to break down proteins.
Stomach cells secrete more mucus to combat it.
Lipase is unable to break down fats.
The medication hampers mechanical digestion.
The medication hampers bile production medication that increases the pH of the stomach and makes it alkaline. Thus, the correct option is A.
What is bile?The liver cells secrete bile, a greenish-yellow fluid made up of cholesterol, waste products, and bile salts, to serve two main purposes: to transport trash away. to digest fats by breaking them down.
Patients with obstructive jaundice or cholestasis have higher serum and liver bile acid levels, which may be harmful to hepatocytes due to their natural detergent properties. Therefore, some of the liver damage in cholestatic liver disorders may be attributed to elevated bile acid levels in hepatocytes.

“lord randall” is an example of a ballad whose structure is
Final answer:
The structure of “Lord Randall” is a traditional ballad form, consisting of four-line stanzas or quatrains with an ABCB rhyme scheme and a rhythmic pattern of alternating iambic tetrameter and trimeter.
Explanation:
“Lord Randall” is an excellent example of a traditional Anglo-Scottish ballad. The ballad's structure typically employs four-line stanzas known as quatrains, with an ABCB rhyme scheme where the second and fourth lines rhyme.
The rhythmic composition often follows a pattern of alternating lines of eight and six syllables, which is characteristic of iambic tetrameter alternating with iambic trimeter.
This structure contributes to the musical quality of ballads, which were traditionally sung, often a cappella or with simple instrument accompaniment, and passed down orally from one generation to another to tell a story, usually containing a lesson or moral.
The repetitions and parallelisms in the dialogue of “Lord Randall” help to advance the narrative and are a hallmark feature of balladic storytelling.
