Mastering biology use the completed punnett square in part b to answer the questions below about the f2 generation. answer each

Sav [38]

1) The probability of F2 seed chosen at random will be yellow is the same as asking about the probability of forming a yellow seed in that generation. The answer is 3/4 (75%) because 1/4 = 25% GG is homozygous dominant and the rest 2/4 = 50% Gg are heterozygous.

2) In the F2 generation there are two genotypes that will breed true, which is homozygotic genotypes: GG and gg. But of these two, only one of them is yellow. The answer is 1/3 because from all the yellow seeds that resulted (GG, Gg and gG) only one has the genotype for true breeding.

3) The probability of taking out three seeds in which a least one is yellow can be calculated by subtracting the only probability that doesn't fit the criterion, which is taking out a green seed 3 times: $\frac{1}{4} * \frac{1}{4} * \frac{1}{4}$ = 1/64.
Then substract that to 1 $1- \frac{1}{64}$ = $\frac{63}{64}$

4) there are three possible groupings in which the green is taken once and the yellow seeds taken twice. The first possibility (follow the example) is the green being the first to come out, another possibility is being the second and the last possibility is being taken in the third time.
For example, Green yellow yellow- probability : 
 $\frac{1}{4} * \frac{3}{4} * \frac{3}{4}$ = 9/64

This is one possibily, but since there are 3, multiply it by 3 and you obtain the final answer:27/64.

How do the reactant molecules become the molecules found in the products... what happens to them

Eduardwww [97]

Explanation:

Molecules of reactants and products undergoes chemical changes when they combine.

The combination leads to the breaking of bonds and rearrangement and this brings about the formation of new products.

Atoms in molecules tends towards stability
They often want to mimic the noble gases and would keep rearranging until stability is attained.
This leads to the formation of new compounds in the product end of the reaction.

Which areas of the brain undergo major growth spurts during middle childhood?

djverab [1.8K]

sensory and motor areas undergo major growth spurts during middle childhood.

The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
The brain is driven by the motor system, which also drives sensory stimulation and feedback.
These abilities must advance and grow in order to support behavior and academic learning.
Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.

Proteins destined for the following locations are sorted in the trans-Golgi:

taurus [48]

Answer:

A

Explanation:

Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.

In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.

Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).
