When molecules are exposed to heat, they
A
stop moving completely.
B
begin to slow down.
C
start to move faster.
D
explode.
Answer:
C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

8 What is the complimentary mRNA sequence to the DNA sequence A-T-T-G-C-A.
Answer:
T-A-A-C-G-T
Explanation:
mRNA → Polypeptide
In order to translate an mRNA sequence into a polypeptide chain, it is important to establish the correct reading frame
The mRNA transcript is organised into triplets of bases called codons, and as such three different reading frames exists
An open reading frame starts with AUG and will continue in triplets to a termination codon
A blocked reading frame may be frequently interrupted by termination codons
Once the start codon (AUG) has been located and reading frame established, the corresponding amino acid sequence can be deduced using the genetic code
Example: (mRNA) GUAUGCACGUGACUUUCCUCAUGAGCUGAU
Answer: (codons) GU AUG CAC GUG ACU UUC CUC AUG AGC UGA U
How do Newton's Laws apply to the way an object moves?
Answer:
Force equals mass times acceleration.
Acceleration is directly proportional to force and inversely proportional to mass. This means that if you get pushed, the harder you are pushed, the faster you'll move (accelerate). The bigger you are, the slower you'll move.

Identify one species that is native to your geographical region in the United States. Speculate on how that species might be affected if they were to live in a warmer and wetter climate and then cooler and dryer climate.
Answer:
I live in the central region of the state of Florida in the Southeastern United States. The climate here is humid subtropical, with a defined rainy season from May through October. This season also sees afternoon thunderstorms that drop heavy but brief summer rainfall.
Florida is home to the largest population of American alligators (Alligator mississippiensis). Alligators are usually found in freshwater. They can only tolerate salt water for brief periods, because they do not possess salt glands to process the salt.
Because of strict conservation measures, the alligator (Florida’s official state reptile) has recovered from its former endangered species status. It remains under threat for habitat destruction because of the construction of water-management systems and increased levels of mercury and dioxins in the water supply. In a warmer and wetter climate, the alligator would be expected to thrive unless habitat destruction continued in that climate. In a cooler and dryer climate, the alligator would suffer from lower temperatures and loss of freshwater habitat.

In humans, as well as in many other animals and some plants, the sex of the individual is determined by sex chromosomes. The sex chromosomes are one pair of non-homologous chromosomes: XX represents a female, while XY represents a male. When a gene for a specific trait is attached to the X or Y chromosome, we say it is sex-linked, and when it is attached to the X chromosome, we say it is X-linked. Alleles for these linked traits, such as hemophilia or color blindness, crosses, may be recessive or dominant.
Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllele but it can still be passed on through generations. Imagine a female is a carrier for hemophilia; her genotype is XHXh. She is married to a man who does not have hemophilia. What conclusion is NOT valid concerning this genetic cross?
A) 0% of female offspring will have hemophilia.
B) 100% of the male offspring will have hemophilia.
C) There is a 50% chance that male offspring will have hemophilia.
D) The chance that female offspring will have the allele for hemophilia is 50%.
Answer:
B isn't valid
Explanation:
As you observe from the diagram above, the second offspring (a male) doesn't have haemophilia disproving option B

crystal size and rock texture
On Edge 2020
Answer:
Crystal Size and Rock Texture
Explanation:
Extrusive rocks are also known as volcanic rocks. Igneous rocks are classified according to their texture and mineral or chemical content. The texture of the rock is determined by the rate of cooling. The slower the rock cools, the larger the crystals form.
The two features of igneous rocks are determined by their cooling rate are Crystal Size and Rock Texture. Thus, option D is correct.
What are rocks?Rocks has been known as volcanic rocks. Igneous rocks has been classified just according to their texture including the mineral or the chemical content. The texture of the rock has been determined by the rate of cooling. The slower the rock cools, or the larger the crystals form.
Bioclastic rocks are wholly or partially comprised of compacted plant or animal remains. Bioclastic rocks will often have fossils within them upon discovery. Most sedimentary rocks contain either quartz (siliciclastic rocks) or calcite (carbonate rocks).
Bioclastic sedimentary rocks are clastic sedimentary rocks, where the broken pieces making up all or part of the rock happen to be pieces of biological life forms- most typically, these are shelly fossil fragments. Most bioclastic sedimentary rocks are marine, mostly because very few land animals leave enough remains to survive being transported.
Therefore, The two features of igneous rocks are determined by their cooling rate are Crystal Size and Rock Texture. Thus, option D is correct.

Which of the following is NOT a type of transportation used in plants?
Individual cells
O Root to stem
O Cell to cell
Transport of sap within the xylem and phloem
Answer:
Transport of sap within the xylem and phloem
Explanation:
After photosynthesis sugars move through the mesophyll via plasmodesmata; here, they reach phloem sieve tube elements in vascular bundles. From the STEs, they are actively transported against their concentration gradient to the phloem.
When the sugars enter the phloem, water moves across from the xylem tube into the phloem. This increases the water pressure inside the phloem, causing the sap to move towards sinks.
Thus translocation of sap only involves the phloem.

The force of attraction between 2 objects is called gravity. Why do you think that an object, like your notebook, pulled towards you? Explain your reasoning.
Answer:
So i just finished doing this project and this what i put, I hope this helps (:
Explanation:
1. When mass 1 increases the force between the objects increases. If Mass 2 decreases, the force between the objects decreases
2. An object with more mass has more/less gravitational force than an object with a smaller mass. Objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases.
3. The forces are equal (Newton's third law of motion)
4. The force between the spheres will quadruple
5. ( I dont know what this is )
6. The force of gravity exerted by the notebook on you is negligible
--The force of gravity
If there is a force between all masses, why are you not pulled toward your desk by the desk’s gravity when you walk away from it? Remember that the net force on you determines how your motion changes. The force of gravity between you and the desk is extremely small compared with other forces constantly acting on you, such as friction, the force from your muscles, Earth’s gravity, and the gravitational pull from many other objects. The strength of the gravitational force between two objects depends on two factors, mass and distance. The Mass of the Objects The more mass two objects have, the greater the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
--The Distance Between the Objects
As distance between the objects increases, the force of gravity decreases. If the distance is doubled, the force of gravity is one-fourth as strong as before.
--Gravity on Earth
The force of gravity acts on both masses equally, even though the effects on both masses may be very different. Earth’s gravity exerts a downward pull on a dropped coin. Remember that every action force has an equal and opposite reaction force. The coin exerts an equal upward force on Earth. Because the coin has an extremely small mass compared with Earth, the coin can be easily accelerated. Earth’s acceleration due to the force of the coin is far too small to notice because of Earth’s large mass. The acceleration due to Earth’s gravity is called g and is equal to 9.8 m/s2 at Earth’s surface. You can calculate the force of Earth’s gravity on an object at Earth’s surface using the object’s mass and this acceleration. The formula that expresses Newton’s second law is F = ma. If you use g as the acceleration, the formula for calculating the force due to gravity on a mass close to Earth’s surface becomes F = mg.
The force between the items grows as mass 1 increases. The force between the objects reduces if Mass 2 decreases.
What is gravitational force?An item with a larger or lower mass will exert a more or less gravitational pull. The gravitational pull between two objects varies depending on how close or far they are to one another.
The force between two items weakens the more apart they are from one another. (Newton's third law of motion) the forces are equal.
Four times as much power will exist between the spheres. The notebook has very little gravitational pull on you, the gravitational force.
Therefore, keep in mind that your motion is affected by the total force acting on you.

Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.The chloroplasts collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars. Animals can make use of the sugars provided by the plants in their own cellular energy factories, the mitochondria. ... The energy cycle for life is fueled by the Sun.
