Two groups of tomatoes were grown under laboratory conditions, one with humus added to the soil (Group 1) and the other a control without humus (Group 2). The leaves of the plants grown without humus were yellowish (less green) compared with those of the plants grown in the humus-enriched soil. The best explanation for this difference is that the: Group of answer choices
Answers
Answer:
the humus contains the minerals necessary for chlorophyll synthesis
Explanation:
The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.
Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.

Answers
Answer:
Increase by a factor of 1,000
Explanation:
As a cell increases in size, there is also a corresponding increase in the surface area and volume. It is however important to note that the volume increases faster than the surface area.
Since it was said that the surface area increased by a factor of 100 and knowing that volume increases factor, the increase in the factor of the volume must be higher than 100. The only option which has a higher factor is the increase by a factor of 1000 which is the right choice.

After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.there are no specimens on the slide b.the microscope is not plugged in. c.she hasn't fastened the slide to the stage. d.the microscope is not yet in focus
Answers
Copied but correct answer.
Answer: C (She hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Stella can not able to see any life forms in the microscope because she hasn't fastened the slide to the stage. Thus, the correct option is C.
What is Microscope?A Microscope may be defined as an instrument that constructs an enlarged image or view of a small object, thus illustrating details too small to be seen by the unaided eye.
If the microscope is not plugged in, Stella will not able to see even white light. If the microscope is not in focus, then Stella is able to see a transparent sheet of fil under it. No specimens also provide a transparent appearance.
But a view of white light indicates that she hasn't fastened the slide to the stage.
Thus, the correct option is C.

A threat stimulus, such as the sight of a predator, triggers a fear response in the amygdala, which activates areas involved in preparation for motor functions involved in fight or flight. It also triggers release of stress hormones and sympathetic nervous system.
The sympathetic nervous system doesn't destress the body once the tree is felled or the danger has passed. Another component of the autonomic nervous system, the parasympathetic nervous system, works to calm the body down, according to the Clinical Anatomy of the Cranial Nerves, published in 2014 by Academic Press

D. Observations are made in a test tube.
Answers
Answer:
Observations are made in a test tube.
Observations are made in a test tube describes an in vitro experiment. So, the correct option is (D).
What is In vitro experiment?In vitro experiment are defined as experiments with microorganisms, cells or biological molecules that are outside their normal biological context. These are called "test-tube experiments" where studies in biology and its sub-disciplines are traditionally performed in labware such as test tubes, flasks, petri dishes, and microtiter plates.
These are relatively low cost experiments which save a lot of time. These are relative simplicity, species specificity, experimental control but are physically limited. Examples of in vitro experiments are organ-on-a-chip, micro physiological systems, cell-based screening, diagnostic tests.
Thus, Observations are made in a test tube describes an in vitro experiment. So, the correct option is (D).

Which of the following describes the structure of an amino acid? A. Small molecules consisting of a phosphate group, a sugar, and a nucleotide base B. A long chain of carbon atoms connected to oxygen and hydrogen atoms C. A long chain of protein molecules D. Small molecules consisting of an amino group, a carboxyl group, and a side chain
Answers
Answer:
i think option d is the answer.
The small molecules consisting of an amino group, a carboxyl group, and a side chain describes the structure of an amino acid.
What are the functions of amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, from which proteins are composed.
Amino acids function as the building blocks of proteins. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues.
Amino acids connect to form peptide bonds through a reaction between the amino group and the carboxyl group. The amino functional group is therefore critical to building all the proteins that makeup life on earth.

explain which mixture most likely produced more ATP. The mixture of yeast and water only OR the mixture of yeast, water and sugar. Support your answer using observation and knowledge of cellular respiration.
Answers
Answer:
The mixture most likely to produce more ATP is the mixture of yeast, water and sugar
Explanation:
In cellular respiration metabolic reactions take place in the organism's cells that makes adenosine triphosphate, ATP, from the chemical energy in nutrients or oxygen with the release of waste products
Yeast which is a Eukaryotic organism produces an addition of or an extra 34 molecules of ATP per molecule of glucose, when placed in the presence or have access of glucose
A high proportion of the produced ATP are by aerobic respiration requiring oxygen
While yeast produces 2 ATP per molecule of glucose by glycolysis'
Therefore, more ATP is produced in the presence of sugar which is a disaccharide of glucose and fructose.
