Answer:
One pair of homologous chromosomes.
Explanation:
One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
Answer:
The corect answer is D) Reaction velocity inceases upto a certain level before decreasing
Explanation:
Reaction rate is directly proportional to the reaction temperature.If the temperature is increased the reaction rate increases and reaction rate decreases with fall in temperature.
Increase in temperature increases the entropy or randomness of the system in which the reaction is occurring.As a result the movement of reactant molecules also increases with an increase in the collision among reactant molecules.Thus reaction rate increases with increase in temperature.
But this is true for increase in temperature upto a certain after that increase in temperature decreases the reaction rate.
Answer:
they have no cell walls.
Explanation:
Mycoplasmas that belong to Firmicutes are considered as pleomorphic because they have no cell walls in their structure. Mycoplasmas have the following characteristics i.e. the smallest mycoplasmas are 125–250 nm in size, they are highly pleomorphic because they lack a rigid cell wall and instead of cell wall they are bounded by a triple-layered “unit membrane” that contains a sterol in its structure.
Answer:
Greenhouse effect
Explanation:
Carbon-dioxide, methane and water vapor are green house gases, these gases absorb a large proportion of sunlight been reflected by the surface of the Earth. These absorption of sunlight leads to gradual increase in the annual temperature of the Earth. This phenomenon is known as greenhouse effect.
Answer:
It would be the plant type
Explanation:
This is because you are measuring the growth of 2 different plants, so they can not be the same. all the other options ARE constants
