CaHeK987 [17]

Answer:

The correct answer is - 75% or 3/4.

Explanation:

In the given question, there is a cross between III-6 and III-7 that produced two double eyes monsters and expected one more. As given in the image that the A or single eye is dominant over the a or double eye then both parents must be heterozygous as they produced double eye offspring (aa) and they do have only one eye.

then chances of single eye offspring would be -

cross: Aa and Aa

gametes: A, a and A, a

Punnett square:

           A      a

A         AA     Aa

a         Aa      aa

so there are 75% chances to have a single eye and 25% chances for a double eye.

What is the difference between metaphase in mitosis and metaphase II in meiosis? How are they the same?
lora16 [44]

Answer:

What is the difference between Metaphase 1 and Metaphase 2? In Metaphase I, the 'pairs of chromosomes' are arranged on the Metaphase plate while, in the Metaphase II, the 'chromosomes' are arranged on the metaphase plate. In Metaphase I, the spindle fibers get attached to two centromeres of each homologous chromosome.

In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. Moreover the in metaphase 1 of meiosis there is no centromere division whereas in metaphase of mitosis it does. They align on the metaphase plate in between the poles.

The rate of firing of the postsynaptic neuron depends on the amount of ______ input it receives from the presynaptic neuron.
DIA [1.3K]

The correct answer is d. both excitation and inhibition.

There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).

How does energy move through your ecosystem? think about the producers (plants) and how energy moves from producers to other org
GrogVix [38]
The Sun provides energy for the plants (producers) to grow. Herbivores (primary consumers) then eat the producers for energy. Any animals that eat the herbivores are considered secondary consumers. As this cycle continues, energy is lost to the environment as heat.
