Answer: Only options A, B, C and D are true statements
A) One sperm fuses with an egg while the other sperm fuses with the polar nuclei.
B) It results in the formation of a diploid embryo and triploid endosperm.
C) Both sperms involved in double fertilization form within the same pollen tube.
- The diploid nucleus resulting from the second fertilization undergoes meiosis to form the endosperm.
Explanation:
Double fertilization is a process that occurs in only flowering plants. It involves the following:
- A pollen grain produces TWO male gametes
- one male gamete fertilize the egg to form a zygote that is DIPLOID (with two basic sets of chromosomes)
- the second male gamete fuses with another cell named POLAR NUCLEI, to form endosperm (the food storing tissue) in the seed. The endosperm formed is TRIPLOID ( it has three sets of chromosomes), having undergone reductive division - meiosis
Thus, the options A, B, C and D are true statements

Answer:
Perception
Explanation:
When a person is given some sensory information, the receptors of sense organs sense the given information and send it to the brain which analyses and interpret it to make the required response.
Likewise, when someone is given a picture of a dog, the photoreceptors see the image and send the sensory information to the brain. The brain analyzes the sent visual information and identifies it as a dog based on previous experience.
The process of sensing the information followed by its analysis and interpretation by the brain to develop the required understanding is called perception.
Answer:
Both the lithosphere and asthenosphere are part of Earth and are made of similar material. Lithosphere is made up of Earth's outermost layer, the crust, and the uppermost portion of the mantle. In comparison, the asthenosphere is the upper portion of Earth's mantle (which is also the middle layer of Earth).
Explanation:
FE fe fE fe (top)
FE Fe fE fe (side)
I'm pretty sure that's right... if you are having trouble then use F.O.I.L (first, outside, inside, last) all you have to do is spilt the parent genotype- so instead of ffEe, you have ff Ee- then you do the first letters (fE), then the outsides (fe), then the insides (fE), then the lasts (fe). hope this helps!! :)
