Describe how gravitropism in roots is different from gravitropism in shoots.
Answer:
Gravitropism is the movement or growth of a plant in response to gravity. ... Plant shoots demonstrate negative gravitropism since they grow in the opposite direction of gravity. Gravity is sensed by specialized cells called statocytes, which have statoliths that sink inside the cell.

Doctors often use certain medications to treat infections. A few people have a reaction to some of these medications, such as itching, swelling, or trouble breathing. This is an example of *
Answer:
Allergy
Explanation:
Allergy occurs when the body system reacts to the introduction of a foreign substance. The immune system plays an important role in the elimination of substances that are capable of causing harm to the body, substances that trigger an allergic reaction in the body is known as allergen.
When an allergen is introduced into the body, the immune system views it as an intruder that is capable of destroying various tissues and cells. It therefore manufactures antibodies to fight off the intruders thereby resulting in an allergic reaction.
Medications such as antibiotics can cause allergic reactions such as itching and swelling of the skin.

Please help! What can be concluded from this graph?
Answer:
i believe the answer is C
Explanation:
The conclusion from this graph is the enzymes lowers the energy of activation for this reaction. Therefore, option (C) is correct.
What do you mean by activation energy?Something that reduces the activation energy is called a catalyst. An enzyme is its biological name. Without being consumed, the catalyst speeds up the rate of the reaction.
By reducing the amount of energy required for reactants to combine and react, enzymes typically reduce activation energy. For instance: Reactants are brought together by enzymes so that they do not have to move around until they randomly collide.
Removal of reactants from the solution state, also known as desolvation. weakening the bonds between the enzyme and the reactants.

How can a genetic mutation lead to an adaptation in a species
Answer:
well if a species has a mutation that helps it in its enviroment it will most likely live longer and get to reproduce more causing more of that same mutation therefore causing an adaptation.
Explanation:
In Alaskan malamute dogs, the allele for dwarfism (d) is recessive to the allele for normal-size dogs (D) and the allele for white coat colour (r) is recessive to the allele for brown coat colour (R). A breeder crosses two malamute dogs, both of normal-size and brown coat colour multiple times. During these multiple times, the following puppies were produced: Normal-size/brown coat colour: 18 Normal-size/ white coat colour: 6 dwarfism/brown coat colour : 6 dwarfism/white coat colour: 2 What genotype are the parent dogs?
Answer:
DdRr
Explanation:
The parents are heterozygous with the genotype DdRr.
Assuming the two genes are independently assorting. For standard, independently assorting genes, the phenotypic ratio for a dihybrid cross should be 9:3::3:1 with the domiant parental gene having the highest frequency, the recessive parental genes having the lowest frequency and the recombined genes having the intermediate frequencies.
DdRr x DdRr
Progeny
9 D_R_ normal size, brown coat
3 ddR_ dwarf, brown coat
3 D_rr normal size, white coat
1 ddrr dwarf, white coat.
The phenotypic frequency is 9:3:3:1.
Now let us look at phenotypic frequency of the outcome
18:6:6:2 is also equivalent to 9:3:3:1.
Hence, the parents are hetezygous with the genotype DdRr.

What would happen if the distance of a planet from the Sun was doubled?
Answer:
Hey! Here are your answers!
1) The Earth would make a double orbit * in terms of time duration of 365.25 days * meaning there'd be about 730.5 days in a year ( a leap year therefore would be every 2 YEARS )
2) Because SOLAR RADIATION (light and heat) takes about 8 mins to reach Earth, this would be double to 16 mins
3) The planet as a whole would cool down significantly to the extent that life cannot exist!
Explanation:
HOPE THIS HELPS!!
According to Kepler's third law, T2 R3, the cube of the mean distance between the planet and the Sun (R) and the square of the time period (T) are exactly related. As a result, the planet's orbital period lengthens by a factor of two.
How does the distance of a planet from the Sun affect it?The orbital period increases and the gravitational pull decreases with a doubled distance from the sun. Depending on how far away from the Sun a planet is, it will have a different orbital speed.
A planet moves more quickly and experiences a stronger gravitational attraction as it gets nearer to the Sun.
It moves in its orbit more slowly the further it is from the Sun because of the Sun's weaker gravitational attraction.
Therefore, the planet's orbital period lengthens by a factor of two.

When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If
an object is slowing down, where is the energy going? (Check all that apply)
The potential energy could be increasing, like a ball thrown into the air.
The kinetic energy could be lost to friction or airfmsistance.
The ball could be returning to its natural resting state.
Due to the conservation of energy, the kinetic energy must stay the same.
Please help
When the motion energy of an object changes, there is inevitably some other change in energy at the same time. If the object is slowing down, where is the energy going?
1. The potential would increase since when the ball is slowing down, its kinetic energy is being transformed into potential energy and when the ball gets hit or kicked again, it releases the potential energy and it transforms into kinetic energy.
2. The kinetic energy wouldn't exactly be lost to friction or air resistance, it's merely being converted into potential energy when the ball is slowing down due to those factors.
3. The ball returning to its natural resting state is correct since according to Newton's 1st Law in which an object that is at rest or is moving will not change unless there is another force acting upon it. in this case, the ball was kicked and there are other forces acting upon it like friction and air resistance, those factors cause the ball to slow down. Eventually the ball will stop and return to its original resting state.
4. This one is incorrect since kinetic energy is not staying the same as the person or any other force that is exerted on it be increased therefore increasing the kinetic energy.
