What are some DISadvantages of interdependence of animals and plants? (at least 3 examples)
Answer:
1. Disease
2. If a new animal species were to be introduced
3. If a new plant species were to be introduced
Explanation:
1. Because of the closeness between plants and animals some disease that affect one species can affect the other.
2. If a new species was introduced it would affect the vegetation (by eating it or by ruining it when walking over it), which can create a problem for animals that rely on those plants for food, mainly herbivores.
3. If a new species of plant was introduced it could be poisonous to animals which could kill them or it could grow larger than small ground shrubs and cover them from the sun, therefore depriving them of sunlight for photosynthesis.

Yeast is used to make the bread fluffy. Can you compare this with respiration?
Answer:
Yeast works as a leavening agent in bread, changing the sugars in dough into gas, which creates the bubbles in the loaves. … However, because yeast will eventually switch from aerobic to anaerobic respiration, the yeast will run out of nutrition -- oxygen.

Diagnosis of Gardnerella vaginitis is made by the appearance of _____. anaerobes in a microscope slide clue cells epithelial cells endotoxin
Answer: The correct answer to the question is option B
CLUE CELLS.
Explanation: Gardnerella vaginitis is also known as bacteria vaginosis.
It is a disease of the reproductive system that affects mostly women of child bearing age, bacteria vaginosis occurs when there is a shift or change in the normal balance of bacteria found in the Vagina,this change in bacteria balance results in infection.
Symptoms of includes vaginal itching, abnormal vaginal discharge and odour.
When Gardnerella vaginitis is diagnosed,the following are being noted;
Clue cells; this involve coating vaginal skin cells with bacteria,clue cells are visible on microscopic exam of vaginal fluid.
When vaginal fluid is tested and the PH shows low acidity( a PH greater than 4.5 precisely).
(WHIFF TEST)When there is a fishy odour upon combination of vaginal discharge with a drop of magnesium hydroxide. A glass slide is used for this test.

An ecologist collected climate data from two locations. The graph shows the monthly average temperatures in the two locations. In Location A, the total yearly precipitation is 273 cm. In Location B, the total yearly precipitation is 11 cm. Whats the answer?
Answer:
More organisms are present on location A.
Explanation:
Due to more yearly precipitation, there is more vegetation present on location A. Due to the presence of this vegetation, more organisms are present because there is more food available for organisms as compared to location B. Due to less precipitation, there is less or no vegetation is present on location B and organisms are present in less number due to harsh environmental conditions and no food availability for organisms.
A box is pushed across 10m by a force of 40 N in 10 seconds.calculate the power.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{40 \: watt}}}}}[/tex]
Explanation:
Given,
Distance ( D ) = 10 m
Force ( F ) = 40 N
Time taken ( T ) = 10 seconds
Calculating the power:
[tex] \boxed{ \sf{power = \frac{work}{time} }}[/tex]
⇒[tex] \sf{power = \frac{force \times distance}{time} }[/tex]
⇒[tex] \sf{power = \frac{40 \times 10}{10} }[/tex]
⇒[tex] \sf{power = \frac{400}{10} }[/tex]
⇒[tex] \sf{power = 40 \: watt}[/tex]

What section of a lab report should be phrased in an "If (cause), then (effect)" statement?
le
Answer:
The HYPOTHESIS
Explanation:
In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.
The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).

"Immediately prior to ventricular systole, pressure in the aorta is about" "The Frank-Starling law of the heart states that"
Answer:
80 mm Hg
Explanation:
Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.
List five such bonds or interactions. Select the five correct answers. Select the five correct answers. coordination bond peptide bond metallic bond hydrophobic bond glycosidic bond hydrogen bond disulfide bond ionic bond phosphodiester bond.
Provided question is incomplete as proper information is not given, however, the complete question is as follows:
Several different kinds of bonds or interactions are involved in generating and maintaining the structure of proteins. List five such bonds or interactions.
Select the five correct answers.
Answer:
The correct answer is:
peptide bond
hydrogen bond
ionic bond
disulfide bond
hydrophobic bond
Explanation:
In protein structure their are different type of bonds present in between different atoms of amino acid to forming or maintaining the protein and its structure. These bonds are as follows:
Peptide bond: These bonds are present in all amino acids, joins monomers in primary structure
Hydrogen (not between R groups): these are bonds present in all amino acids, these bonds are responsible for the secondary structure .
Hydrophobic: leucine could be involved, These type of interactions are responsible for tertiary and Quaternary structure
Ionic: glutamate could be involved in such bond, these are also responsible for the tertiary and Quaternary structure
Disulfide: cysteine could be involved in such bonding, tertiary and Quaternary structure
