Researchers argue that some bacteria found in the human gut are in a symbiotic relationship with humans, called mutualism. Which

of the following observations is consistent with this argument?

Answer:

Bacteria provides vitamins to humans

Explanation:

The correct answer would be that bacteria provides vitamins to humans.

<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>

Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.

<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>

Evaluate the relative environments inside and outside the cell when a cell is said to be in dynamic equilibrium with its environ
zloy xaker [14]
<span>When a cell is in a dynamic equilibrium with its environment, this means that the salt/water concentration inside the cell is equal to the salt/water concentration outside the cell. It is called an equilibrium because no transport of molecules is needed since the concentrations are already the same.</span>

Note 1: Balanced forces do not cause alterization motion or movement. This is because of the fact that balanced forces are equal in size and in opposite directions. Consequently, this leads to cancellation and ultimately no movement.The net force for balancing forces is always 0.

Think of it this way: Take your right hand and left hand. Press them together; palm-to palm and five fingers to five fingers. Now apply equal amount of pressure (your force) as you push them in opposite directions (left hand left direction right hand right direction) Does any change in movement occur? 

Note 2: Unbalanced forces are the forces that cause change in movement and motion. When two unbalanced forces are exerted in opposite directions, the overall force (or net force) is the difference between the two forces and the direction is in favor for the larger force. 
Think of it this way. Repeat the exercise I shown you in Note 1, but this time, make apply more force in comparison to the other hand. Your right/left hand's force overpowers the weaker force of the opposite hand. The direction is in favor to your right/left hand (since they obtain the bigger force) as your hands move to the right or left side. This is an example of unbalanced forces at play.

Q22: The two forces on the left and right side are balanced given that their force is equal in size and they are in opposite directions. The two forces northwards and southwards are unbalanced forces since they are not equal in size but are opposite in direction. Recall in note 2 when I given the formula to find the net force for unbalanced forces. Its the difference (subtraction) between the bigger force and smaller force. 5 - 2 = 3. Therefore the net force for question 22 is 3.The direction is in the bigger force's direction, therefore southwards. 


Q24: Is a balanced force. Therefore the net force is 0. I don't think there is technically any direction per say.

In peas, tall plants (T) are completely dominant over short plants (t). You cross two heterozygous pea plants Use a Punnett squa
Nikitich [7]

Answers and Explanation:

Find enclosed the Punnet square.

T= dominant allele

t= recessive allele

Tt= heterozygous genotype

TT and tt= homozygous genotype

- The male pea plant's genotype is Tt (heterozygous)

- The female pea plant's genotype is Tt (heterozygous)

- Male gametes: T and t

- Female gametes: T and t

- The expected genotypic ratio of the offpring will be:

TT: Tt: tt ⇒ 1: 2: 1

1/4 of the offpring will be TT genotype (dominant homozygous), 1/2 of the offpring will be Tt (heterozygous) genotype and 1/4 of the offpring will be tt genotype (recessive homozygous).

- The expected phenotypic ratio of the offpring will be:

tall : short ⇒ 3 : 1

3/4 of the offpring will be tall (TT and Tt) and the restant 1/4 will be short (tt).
