alexgriva [62]3 years ago
3 0

Mendel studied inheritance in peas (Pisum sativum). He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate

Yolk molecules tend to accumulate in the vegetal half in the fertilized eggs of most animals, and the presence of yolk can slow
bazaltina [42]

cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.

Explanation:

The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.

The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.

Calculate the net force on the Fx and Fy<br> of<br> 20 N<br> 17 N<br> 45.50<br> 250
marysya [2.9K]

Answer:

F_{net} is 26.25 N

Explanation:

Given that: F_{x} = 20 N, F_{y} = 17 N.

This implies that the two forces are acting at right angle to each other. Thus applying the Pythagoras theorem, we have;

F_{net} = \sqrt{F_{x} ^{2} + F_{y} ^{2}  }

       = \sqrt{(20)^{2} + (17)^{2}  }

       = \sqrt{400 + 289}

F_{net} = \sqrt{689}

      = 26.2488

F_{net} = 26.25 N

The net force is 26.25 N.

What is recombinant dna explain how recombination dna can be used to create insulin
gavmur [86]

rDNA is using genetic cloning to form DNA molecules from different species. in this example you can make the hormone insulin by getting some of the components from one organism and getting the remainder from another organism. Specifically, Insulin has 2 amine chains, so you can get 1 amine chain from one organism, and the other from a different one. Then you can combine them and you'll get insulin.

Supply-and-Demand Schedule for Cell Phones Price of Cell Phones Quantity Supplied of Cell Phones Quantity Demanded of Cell Phone
k0ka [10]

Answer:

$150, $200

Explanation:

A schedule that shows relationship between quantity supplied and quantity demanded is used to estimate the equilibrium quantity and price where there is a balance between the buyer's willingness to buy and the seller's willingness to sell.

Below this equilibrium point there is excess of quantity demanded over limited supply.

Above equilibrium there is excess supply and less demand.

According to the given schedule the equilibrium price is $100 where demand and supply are both 300 units.

The prices at which there are excess supply is given below

At $150 400 units is supplied against 250 units demanded

At $200 500 units are supplied against 0 units demanded

How are learned behaviors related to natural selection?
vlabodo [156]
D. Learned behaviors do not directly affect natural selection because they are not inherited.
This is true because learned behaviors can be taught to the offspring but do not come within them the way instincts do.
