Answers
Answer:
The correct answer is -
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)
Explanation:
In this experiment of Mendel, Mendel selected the pea plant as it has various characters, short life span, and easy to breed. For this, he used two true breed lines, tall plants that had dominant allele TT and dwarf plant tt (recessive). In presence of the dominant allele, recessive alleles do not show their characteristics and only express if both alleles are recessive.
In the first cross of TT and tt
Gametes: T and t
offspring: Tt
the offsprings are all tall and heterozygous which means one dominant and one recessive allele.
second cross or F1 × F1
Tt × Tt
gametes: T, t and T, t
offspring: TT, Tt, Tt, tt
Thus,
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)

What do Doodle’s repeated pleas of “Don’t leave me” foreshadow?
Answers
Doodle's repeated cries of "Don't leave me" hint at a later event in the novel where the narrator rushes forward and abandons Doodle to struggle behind. The passage from "The Scarlet Ibis" is the inspiration for this.
What type of character is Doodle?
He is a rounded character because as the narrative progresses and he ages, he picks up numerous flexible and eccentric traits including tenacity, frailty, being underestimated, imagination, and dependency. Because she is only identified by a few characteristics, Aunt Nicey has a flat personality.
Scarlet ibis and Doodle are similar. He is despised by his family because he is clumsy. They anticipated that he wouldn't survive. The scarlet ibis, which likewise exhibits extreme weakness like Doodle, serves as a metaphor for him.
The narrator rushes on, leaving Doodle to struggle behind during a violent storm, as foreshadowed by Doodle's frequent cries of "Don't leave me."

Answers
Answer: The phloem tissue layer
Explanation: The phloem tissue of a plant is one of the vascular tissues of higher plants responsible for the conduction or transportation of photo-synthetically manufactured food (usually in the form of sugar) round the body of the plant to the various tissues and organs that require it.
The tissue moves food materials from their source of manufacture, usually the leaf, to other parts of the plant. Hence, in order to extract the syrup from the maple tree, the phloem layer must be tapped into.

The planets like Uranus and Neptune are found at outermost part of the Solar system, since they are located after the asteroid belt.All of these outer planets are much larger then the internal ones so they are also known as "ice giants". The other reason for this name is that they are very distant from the Sun, so their temperature is low.Another feature they have in ordinary is their atmosphere which is composed of gases, including methane, which is accountable for their blue color, since methane absorbs red light.However Neptune is known for very short winds and storms in its atmosphere which is accountable for its high action and changes.

Doubling the amount of water a person drinks daily.
Drinking caffeinated beverages several times a day.
Answers
An increase in alcohol consumption
Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.

What do we call Earth's orbit around the Sun?
intergalactic movement
Earth's revolution
Earth's rotation
galactic movement
Answers
Answer:
Earth's revolution
How do we know that the earth orbits the sun?If you study the stars and know where all the planets on the solar system are, you will notice that those stars alternate their motion in the sky, which means they do not orbit the Earth. In fact, the word "planet" originally means tricky star, suggesting that those "stars" did not behave like other normal stars.
The theory of universal gravity cannot be denied, since we are able to send satellites to outer space and have them orbit our plant. In fact, we are able to derive equations to figure out how fast the satellite need to orbit around the earth in relation to how high above the surface of the earth it is. The same mathematics that derived said information had also been used to derive the geosynchronous height from the Earth, which is the height at which a satellite orbiting the Earth, with the necessary speed to stay in circular orbit (not elliptical orbit), matches the Earth's rotation about its axis. Geosynchronous satellites are used for T.V. broadcasting and many other applications.
The formula for universal gravitation is GMm/r2, which means that the force of gravity on an object by another object are proportional to the masses of both objects, and inversely proportional to the square of the distance between them, and this proportion is multiplied by a constant G. It makes greater sense that the Earth revolves around the Sun, and not the other way around, because the mass of the Earth is way too small to apply a force strong enough to create a large enough acceleration on the sun to keep it in orbit around the Earth. If the Earth had enough mass to cause that huge of a gravitational force, then the moon will not remain in orbit around the Earth, but will fall closer the Earth and hit the Earth.
What is the revolution of a planet?The process through which a planet, let's say the earth, revolves around a huge mass that is significantly larger than the planet, such as the sun or any star. And the gravity between the two bodies is what causes this process to occur.

2. Why is an amniotic egg an evolutionary leap for reptiles? 1It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. 2 It allowed for many offspring to be made at the same time. 3 It allowed female reptiles to lay their eggs and leave the young to fend for themselves. 4It allowed for asexual reproduction by females only.
Answers
It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. Option 1.
Evolutionary advantage of the amniotic eggThe amniotic egg enables organisms to live their lives entirely away from water.
Prior to the evolution of the amniotic egg, the egg being laid by animals cannot survive on land. Also, the fertilization of the eggs requires water.
The amniotic egg is equipped with features that enable it to survive conditions on land. The external shell and the amniotic fluid protect the embryo from mechanical damage and dehydration. Gaseous exchange and waste excretion of the embryo are taken care of by the allantois and the chorion.
