In the slow block to polyspermy, sperm penetration releases an inflow of Ca2+, which in turn stimulates the cortical reaction.

<h3>What is cortical reaction?</h3>

A medium known as the cortical response, which is started after fertilization, stops polyspermy, or the union of several sperm with one egg.
The cortical response, which in numerous species serves as the top element of the slow block of polyspermy, gradationally forms a endless hedge to sperm entry in discrepancy to the rapid-fire block of polyspermy, which instantly but temporarily inhibits new sperm from fertilizing the egg.
This barrier is made up of the egg's plasma membrane and cortical granules, specialized secretory vesicles found in the cortex (behind the plasma membrane) of the egg.

<h3>What follows the cortical response?</h3>

Cortical granules (CG), a type of specific organelle in the egg, release their contents into the perivitelline region after sperm and egg fuse (cortical response), making the zona pellucida resistant to sperm adherence and penetration.

Firdavs [7]

Answer:

13.75%

Explanation:

Calculation for what will be the company's return on equity

First step

Asset Turnover Ratio= Net Sales / Total Assets ------(1)

Given Asset Turnover Ratio =2.7

=> 2.7 = 4,000,000/ Total Assets (from equation 1)

=>Total Assets = 1,481,481 ------(2)

Second step

ROE = Net Income / Equity

Net Income = (EBIT - Interest Charges) *(1-tax rate)

Net Income = (356,000 -168,000) *(1-35%)

Net Income = $122,200 --------(3)

Equity = Total Assets *(1-debt ratio)

Equity = 1,481,481*(1-0.4) = $888,889 --------(4)

From equation 3 and 4

ROE = Net Income / Equity

ROE= 122,200/888,889

ROE =0.1375*100

ROE=13.75%

Therefore ROE will be 13.75%

A company purchased $1,800 of merchandise on July 5 with terms 2/10, n/30. On July 7, it returned $200 worth of merchandise. On

pychu [463]

Answer:

The correct answer is C

Explanation:

The amount of cash paid on July 8 is computed as:

Amount of goods worth = Purchased amount - Returned goods worth Amount of goods worth = $1,800 - $200

Amount of goods worth = $1,600

As the amount is paid within the terms of 10 days, so the amount is eligible for the discount of 2%, it is as:

Amount to be paid in cash = Amounts of goods worth - ( Amounts of goods worth × Discount)

where

Amounts of goods worth is $1,600

Discount is of 2%

Putting the values above:

Amount to be paid in cash = $1,600 - ($1,600 × 2%)

Amount to be paid in cash = $1,600 - 32

Amount to be paid in cash = $1,568

If we have eight decisions to make and 3 choices for each decision, how can we represent the number of potential outcomes

AveGali [126]

We can represent the number of potential outcomes by 3 to the power 8.

<h3>What is permutation and combination?</h3>

Permutation relates to the act of arranging all the members of a set into some sequence or order.

We can assume, for two choices, we have one decision. This can be represented as, since we have eight decisions,

Representation of the potential outcomes are:

= 3^1 + 3^1 + 3^1 + 3^1 + 3^1 + 3^1 + 3^1 + 3^1

= 3^8

= 6,561

Calculation for Ron’s Tax bases

Using this formula

Ron’s Tax bases=Basis of the property contributed-Mortgage

Let plug in the formula

Ron’s Tax bases=$60,000-$40,700

Ron’s Tax bases=$19,300
