Answer:
B. Catastrophism
Explanation:
Catastrophism is the theory that states that the Earth was mostly shaped by very sudden effects. These sudden and short-lived events would occur worldwide in scope and change the Earth rapidly. This is in contrast to uniformitarianism that states that slow incremental changes made the Earth like it is today. Changes like erosion.

Convoluta worms hatch in early spring. They crawl about in the mud feeding on algae, which find their way into the skin of the worms. There they prosper as they worms feed on the sun-warmed surface mud.
The worms become greener and greener as they mature. Gradually their mouths seal shut, leaving only an internal garden of algae to provide them with food. As winter approaches, their food supply is exhausted, and the worms grow pale again. They lay their eggs in the mud just before they starve to death.
How do you think both worms and algae benefit from this relationship? WHY??

Identify all statements that accurately describe the structure of the pyruvate dehydrogenase (PDH) complex.A. A regulatory kinase and phosphatase are part of the mammalian PDH complex. B. Several copies each fo E1 and E3 surround E2. C. E2 contains three domains. D. The complex contains multiplex is made up of several copies of E1.
Answer: Options A, B ,C and E are correct
Explanation:
The structure of pyruvate dehydrogenase complex comprises if three enzymes E1, E2 and E3 which convert pyruvate to acetyl CoA. The three enzymes are have several copies.
Within the PDH complex, the E2 subunit forms the structural unit, contain three domains and are surrounded by E1 and E3. The E 2 accepts acetyl groups from E1 and transmit the group to coenzyme A. The decarboxylation of pyruvate and its conversion to acetyl-CoA by the PDH complex comes first before glucose carbon enter into the tricarboxylic acid (TCA) cycle. This process is important to the aerobic oxidation of glucose .

force=
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Explanation:
2. The experiment proceeded as normal, with the experimental group hearing about the
potential presence of a gun as the confederates left the study and the control group not
hearing about the gun. All participants returned on day two for the interview with the
police detective. After debriefing, none of the participants said they were aware that the
theft was staged. The researchers found that those in the experimental group did
incorporate the gun misinformation into their memories of the theft more than those in
the control condition. That is, the mean score that a gun was present was much higher for
the experimental group (M= 67%, SD = 12.4%) than the control group (M= 33%, SD =
11.16%).

Use the drop-down menus to identify the type of mass movement in each image.
A: First image
B: Second image
C: Third image
(Answers: creep, mudflow, and slump)
Answer:
First Image - Creep
Second Image - Mudflow
Third Image - Slump
Explanation:
In geology, creep in landform is known to be the movement of loose, weathered material which occurs on every slope slowly on a downslope. The downslope is caused by persistent tilting of gravestones, trees, etc.
Mudflow involves the very rapid flow of debris which are liquified as a result of the significant amount of water which then leads to mass wasting. This occurs when water mixes with soil and rock and makes the mud mass to flow rapidly.
While slump involves the falling out or removal of earth ir rock debris from the slope of unconsolidated material which moves downward intermittently.
Creep, Mudflow and Slump all lead to landforms.

textWhere are nonpolar amino acids of a protein more likely to be found? Check all that apply
Answer:
At the interior side.
Explanation:
Nonpolar amino acids of a protein more likely to be found at the interior side of the soluble proteins where they are far from the water because water is a polar molecule and only polar amino acids of protein can interact with the water so that's why the polar amino acids are present on the surface of soluble proteins and the nonpolar amino acids of a protein are present at the interior side of the soluble proteins due to its nonpolar nature.

What kind of change results from the breakdown of starch into glucose by saliva? Physical or chemical ?
Answer:
Yes im doing the science final
The change results from the breakdown of starch into glucose by saliva is chemical change.
What is chemical change?When bonds between molecules or atoms are created, disrupted, or both, chemical changes result.
In other words, a substance with one set of qualities gets changed into another substance with a different set of attributes.
Chemical decomposition is the term used to describe the subsequent chemical change as more products are produced as a result of this process.
When two materials interact to form a new substance, chemical synthesis—or, conversely, chemical breakdown into two or more independent molecules—occurs.
The starch gradually transforms into sugar when saliva is supplied because saliva contains the enzyme amylase, which helps break down starch.
Starch is a polysaccharide made up of many units of glucose. Amylase breaks down starch to produce a disaccharide called maltose.
Thus, the given one is the example of chemical change.

. Which of the following is used to avoid bias in a clinical trial
A) Data manipulation
B) Unfair prejudice
C) Personal interest
D) Double-blind testing
Answer:
D.
Explanation:
Whenever any clinical trail is conducted then the complete process is kept unbaised. Double blind testing can be defined as an experiment in which neither the researcher nor the person who is getting placebo and who is getting treatment knows. This is done in the clinical trials to keep the whole process unbaised.

Which of the following best describes the process by which the bacteria are breaking down the glucose to produce
lactic acid?
A The bacteria are breaking down sugars in the absence of oxygen.
B The bacteria are creating a H+ gradient to synthesize more ATP.
The bacteria are using their mitochondria to break down glucose in the presence of oxygen.
The bacteria are producing CO2 in the Krebs cycle that is then converted into lactic acid.
Answer:
A. The bacteria are breaking down sugars in the absence of oxygen.
Explanation:
Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.
They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.
In Glycolysis:
2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.
Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.
The option that best describes the process by which bacteria break down glucose to produce lactic acid is when bacteria break down sugars in the absence of oxygen. The correct option would, thus, be A.
Bacteria are capable of breaking sugars to generate energy, a process known as respiration.
This respiration can either be in the presence (aerobic) or absence (anaerobic) of oxygen.
Aerobic respiration has 3 major steps:
sugar is converted to pyruvates with the generation of ATP - glycolysispyruvates enter the Kreb's cycle to generate ATP and other molecules such as FADH2 and NADHFADH2 and NADH produced in Kreb's cycled are used to move electrons and generate energy in the electron transport chain.Both the 2nd and 3rd steps in aerobic respiration require oxygen and the summary of the entire process is in the following equation:
[tex]C_6H_1_2O_6 + 6 O_2 ---------> 6 CO_2 + 6 H_2O + ATP[/tex]
In the absence of oxygen, only glycolysis occurs and the pyruvates generated are quickly converted to lactic acid to generate a small amount of ATP according to the following equation:
Pyruvic acid + NADH <---> lactic acid + NAD+

Abiotic factors are the non-living factors in the ecosystem. These materials are the chemical and physical components of the ecosystem. They are not biological in nature.
Soil minerals are abiotic since they are produced from rocks. Invasive weed species, animals pollinating and disease causing fungal spores are all biotic. They stem from biological processes.Answer:
