What will happen if the pollen tube pore its content inside the embryo sac?
Answer:
Once the embryo sac has developed, pollination has occurred, and the pollen tube has grown into the ovary to make contact with the ovule, fertilization (fusion of egg and sperm) can occur.Typically, the pollen tube reaches the embryo sac via the micropyle (Greek, mikros + pyle = small opening), or opening, in the integuments of the ovule.. There, it discharges its sperm into the embry
Explanation:
The pollen tube enters into the ovule, through the micropyle. Inside the embryo sac, the tip of the pollen tube ruptures and the 2 male gametes are set free near the egg apparatus. Inside the embryo sac, one of the 2 male gametes fuses with the egg nucleus and forms a diploid zygote. This process is called syngamy or true fertilisation.
Answer:
In angiosperms, the pollen tube releases
its contents ( including sperm cells) in
to the embryo sac upon insertion into the
ovule, thus completing double
fertilization

World War II was one of / if not the biggest tragedy to happen in modern history. It taught the world important lessons about society; that we need to work together and not let our differences enable another global conflict to the degree of WW2. However, history never completely repeats itself and while WW2 was a terrible and unimaginable tragedy, it provided us with information that can help us all in avoiding a future conflict similar in nature. However, how is the author so certain that history doesn't repeat itself? Have we not seen history do such thing. For example, there were vaccination protests all throughout history just like how there is vaccination protest today. So, I am interested in how the author came to his conclusion that WW2 will not inevitably repeat itself.

Explanation:
Explain why an earthworm will die if it dries out based on the type of skeleton annelids have and the absence of a respiratory organ or system in the earthworm.
We can confirm, based on the type of skeleton and lack of a respiratory organ, that a worm will die if it dries out due to the fact that the exchange of gases happens through the mucus on its skin.
As stated in the question, Earthworms do not possess any form of respiratory organs. To account for this, they have evolved the ability to breathe through their skin. This ability is due to what is known as a hydrostatic skeleton, possessed by most annelids.
This skeleton is covered in mucus and allows the exchange of gases with its surroundings, therefore, if the worm were to dry up, the mucus that encases the skeleton would harden and thus prevent the interchanging of oxygen and carbon dioxide. Effectively, the worm would not be able to breathe and would die.

Field of View = Field Number (FN) ÷ Objective Magnification
You will have to multiply the eyepiece magnification by the objective magnification to find the total magnification before dividing the field number. For instance, if your eyepiece reads 10X/22, and the magnification of your objective lens is 40.

explain the difference between evolution by natural selection and evolution by artificial selection. an example of each!
Explanation:
Natural selection; Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Weaker animals within a breed being killed off for food for another species, the surviving animals breed and continue the better genes for survival.
Artificial Selection; Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Corn. Larger growing corn was taken for more growth while smaller were eaten and not continued. Humans decdied the larger pieces were better for food.

Answer:
Co2 is released during both lactic acid and alcoholic fermentation reactions.
Water is produced as a result of fermentation reactions.
Explanation:
I took the test and the person above me is correct
Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.
What is respiration ?It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in order to produce energy.
In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4 molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.
Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken down into lactate.

D.behavioral
Which on is it?
Answer:B Natural
Explanation:Camouflage is a adaptation which animals use to blend in with their surroundings in order to protect themselves from the predators and hunters. This also gives them a better chance of survival and easy mode of hunting for food.
For example: white fox hides in the snow from the predators
Camouflage is a clear example of Physical or Structural adaptations.
-Body shape, color and body patterns are the adaptations that assists both predators and prey to camouflage
-As in the example mentioned, the polar bear with its white fur hides in the snow and waits for the right time to attack its prey without being seen
