Answer:
Explanation:
It's hard to distinguish facts/ evidence from the article with only the statement ' Life on earth could not exist without decomposers', but taking that into consideration, it's best if you breakdown the information so you properly understand what it means.
Life on earth - refers to evolution of life on earth such as single celled organisms, eukaryotes, prokaryotes, bacteria and so on
could not exist - refers to the inability of it being there, it's presence is basically there/ not there
decomposers - is an organism that breaks down organic materials from dead organisms to obtain energy such as fungi, bacteria, worms and so forth.
You basically need to relate all the information you find in the 'article' to the statement they have made and which i have broken down for you above.

which plant cell structures provide evidence that plants are living organisms?
Answer:
chloroplasts
Explanation:
Answer:
Chloroplasts or Nucleus
Explanation:
The Nucleus holds DNA, which is in every living thing. However, nucleus' are also in animal cell. Specifically in a plant cell, the chloroplasts provide the evidence since they help the plant make it's own food.
Driving from Maine to Florida, you observe that squirrels living in the southeastern United States are much thinner than squirrels living in the northeastern part of the country. You tell your friend that you have a theory that squirrels living in the northeast have greater fat reserves for the winter months when food is scarce. Which of the statements are true? Select all that apply.
Answer:
See the options and the answer below
Explanation:
The available options to the question are:
Your statement is a valid scientific theory. Your statement uses the word "theory" in a non-scientific, colloquial way. Your statement is a hypothesis rather than a scientific theory. Your statement is not a theory but a fact.The correct answer would be that:
the statement uses the word 'theory' in a non-scientific, colloquial way. the statement is a hypothesis rather than a scientific theory.A hypothesis is a generalized statement with little or no experimental test. When a hypothesis is tested using a suitable experiment (s), it can either become valid or invalid. In order words, hypotheses are falsifiable. A theory on the other hand is a hypothesis that has been tested several times by independent researchers and found to be true.
In the illustration, the statement made concerning the squirrels is based purely on guess and not on fact. The use of the word 'theory' in the statement is totally unscientific. Only suitable experiments can prove or disprove the statement.
The correct options are 2 and 3.
30. An anatomist wishes to make detailed comparisons of
medial surfaces of the left and right sides of the brain. This
work requires sections that show the entire medial surface.
Which kind of sections should be ordered from the lab for
this investigation?
Answer and Explanation: In anatomy, bodies are divided by hypothetical geometric planes to describe location or direction of its structures. These planes are called Planes There are 3 reference planes:
1) Sagittal Plane divides the body into sinister and dexter (left and right) sides.
2) Coronal Plane divides into anterior and posterior portions.
3) Transverse Plane divides into superior and inferior portions.
For the anatomist, to have a section that shows the entire medial surface, should be ordered the Sagittal Plane, more especifically midsagittal (median) plane.

Which of the following is a biotic factors in an ecosystem? O sunlight O nutrients in soil and water O precipitation O microorganisms
Answer:
microorganisms
Explanation:
Biotic factors include fungi,algae,bacteria etc.
While, Abiotic factors include soil, water ,sunlight and minerals
Answer:
[tex]\boxed {\tt D. \ Microorganisms}[/tex]
Explanation:
A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.
An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.
Let's examine our answer choices.
Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.
That leaves: microorganisms. Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms

Which feature do amber fossils have that mold fossils do not?
O preserved soft tissue
O organisms turned into rock
O solid copies of the original organism
O impressions of hard tissue left by organisms
Answer: preserved soft tissue
Explanation: just took the test!
The feature do amber fossils have that mold fossils do not preserved soft tissue. Thus, option A is correct.
What are fossils?
The fossil can be defined as the compression of the animal, plant or some organism that was living. It is compressed by the rocks or or settled in the water bodies in the form of sediments. The fossil residues have some of the carbon left in it.
This carbon is estimated by carbon dating in order to get the age of the fossil.The preserved fossils have carbon residue left which can be used as a source of information.
There are several types of the connective tissues: bones, ligaments, tendons, cartilage, and adipose tissue. In the foot, among all connective tissues, ligaments and tendons are the most abundant types. Ligaments and tendons mostly consist of densely packed collagen, which is the main structural protein of the connective tissues.
Therefore, The feature do amber fossils have that mold fossils do not preserved soft tissue. Thus, option A is correct.

which of the following is most consistent with the modern theory of evolution
The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.
Explanation:
The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.
Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
How are lysosomes and vacuoles the same? How are they different?
Answer:
Vacuole is a cell organelle which contains mainly water while lysosomes also cell organelle and are regarded as bags by function. Vacuoles stores the undigested nutrients while the Lysosomes are the membrane bound sacs containing digestive enzymes that breaks down large molecules.

While you were on safari, your friend got bit on the leg by a posionous snake and nearly died from excessive hemolysis. Being a true scientist, you captured the snake and analyzed its venom to understand why it caused hemolysis. You found thwo enzymes, a protease (breaks down proteins), and a phospholipase. He isolated each of these enzymes and treated red blood cells with them. He found that only phospholipase caused red blood cell lysis. He also found that, after treatment of red blood cells with the phospolipase, there was excess amounts of free phosphophorylcholine (Choline phosphate group) and free diacylglycerol (glycerol with two hydrocarbon tails). 1.) What is the substrate for phospholipase and where does it cleave
Answer:
Phospholipase is an enzyme, which is classified into phospholipase A2 and phospholipase A1.
In this case we are talking about phospholipase A2, that is why the sn-2 ester bond of glycerophospholipids will be taken as a substrate, giving fatty acids as a product, such as arachidonic acid.
Explanation:
The glycerophospholipids used by this enzyme are those found in cell membranes, these pathways are usually associated with inflammation pathways for the formation of arachidonic acid that functions as an immunological mediator.
On the other hand, it must be remembered that membrane phospholipids are amphipathic, that is, with hydrophilic and hydrophobic molecules and are responsible for balancing the internal homeostasis of the intracellular environment.

What are possible products of glycolytic, or anaerobic, catabolism?
Answer:
The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.
Explanation:
Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.
Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.
Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.
This hormone has the opposite effect to glucagon.

Leigh has collected data and performed statistical
tests for analysis. Describe the conclusions she can
draw about the data based on her analysis.
Answer:
She will obtain results to support -or reject- her working hypothesis. These results are subjected to statistical analyses in order to confirm that they are statistically significant
Explanation:
The scientific method is a rigorous process that consists of raising a working hypothesis, which is tested by experimentation or observational procedures and analysis of the results. The statistical analyses may have key roles during this procedure. In an experiment that involves statistical analyses, the results are subjected to statistical measures to evaluate the significance level and thus confirm (or reject) the statements made in the working hypothesis. The p-value is one of the most used statistical measures to determine if differences are due to randomness, or they are statistically significant.
Answer:
Because the calculated chi-square value of 5.19 is less than the critical value of 7.82, the null hypothesis can be supported. She is 95% confident that there is no significant variation in shell color along the beach coastline.
