Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

Which would NOT likely be used as evidence of evolution?
Answer:
what is there to pick from?
Explanation:
The option that does not provide evidence that living things have been evolving for millions of years is intelligence. The correct option is C.
What is evidence?In science, evidence refers to any observations, measurements, or facts that support or refute a hypothesis or theory.
Intelligence is not a factor that provides evidence for evolution. The process of evolution is driven by natural selection, genetic mutations, and other biological factors, not intelligence.
On the other hand, the other answer choices are all factors that provide evidence for evolution:
(A) Fossil record: provides evidence of changes in species over time.
(B) Natural variation within a species: provides the raw material for evolution to act upon.
(D) Homologous structures of living organisms: provide evidence of common ancestry and evolution over time.
(E) Similarities in embryological development: provide evidence of shared evolutionary history and common ancestry.
Thus, the correct option is C.

A cell that utilizes NHEJ to repair a double-stranded DNA break which occurred in the open reading frame of a gene is susceptible to indels resulting in a frame shift mutation and ultimately a non-functional protein. False True
Answer:
True
Explanation:
The non-homologous end-joining (NHEJ) pathway is a DNA repair pathway used to repair double-strand breaks that can occur throughout all cell cycle phases. Conversely to the homologous recombination (HR) pathway, the NHEJ pathway does not need a homologous template at the DNA double-strand breaks ends and therefore NHEJ is an error-prone repair pathway that may cause mutations within the repaired region of the DNA. The NHEJ pathway is well-known to induce indels (i.e., insertions and deletions) mutations that shift the reading frame of the protein (i.e., frameshift mutations), thereby leading to a completely different translated protein from the original one.

Water molecules have a strong attraction to one another.
What property best describes this attraction?
Choose 1 answer:
A
Hydrophobic
B
Cohesion
C
Density
D
Adhesion
Answer:
The correct answer is B: Cohesion
Explanation:
Cohesion is the ability of water molecules to be strongly bonded together. This happens due to the polarity of water molecules. Since water is made up of two positive hydrogen ions that combine with one negative oxygen ion to form a hydrogen bond. Hence, the molecular structure of water enables hydrogen irons to attract oxygen ions that create a strong polar bond between water molecules.

Length of Day (how does it affect plants)
Day length helps plants to regulate their internal clock
source: g00gle
Answer:
When the day length is fewer than 10 hours, most plants do not grow. Even if the temperature is kept within the ideal range — say, in a climate-controlled greenhouse — most plants will go dormant until the magical 10 hours of sunshine per day arrives.
Explanation:
What is sprouting?
Why do we need to have calcium rich foods?
Answer:
(i) Sprouting is the natural process by which seeds or spores germinate and put out shoots, and already established plants produce new leaves or buds or other newly developing parts experience further growth.
(ii) It makes up much of your bones and teeth and plays a role in heart health, muscle function and nerve signaling

Which of the following could result in secondary succession?
the formation of a tall sand dune on a previously grassy beach
a vast glacier in motion forming a U-shaped valley in its wake
a volcanic eruption that covers most of what used to be a forest
an introduced species that destroys all the native plants in an area
Answer:
D. an introduced species that destroys all the native plants in an area
Explanation:
Secondary succession happens when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site.
An introduced species that destroys all the native plants in an area
Example of successionExample of secondary succession is in oak and hickory forests cleared by wildfire.Wildfires burn most vegetation and kill animals which makes it impossible to escape the area.Thus, we can conclude that the correct option is (d)

One function of liver cells is lipogenesis, the process of converting excess dietary carbohydrates to lipids. What organelle in the liver cell performs this function?
Answer:
The smooth endoplasmic reticulum performs this function.
Explanation:
The smooth endoplasmic reticulum is an organelle made of connected membranes. Its function is to synthesize lipids that the cell needs for different activities. When there is an excess of carbohydrates, this organelle transforms them into lipids to storage them and use them when the body needs them.
HELP!!!! FAST!!!! 20 POINTS!!!! You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal
mass (3,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know:
• Truck 1 started from rest at the top of a 22-meter hill and coasted toward the intersection.
.
Truck 2 was on a flat stretch of road at the bottom of the hill directly in front of Truck 1.
At the bottom of the hill, Truck 1 was going 20 m/s; Truck 2 was going 35 m/s.
.
There were no skid marks left by Truck 2. The collision occurred at the stop sign where Truck 2 had
stopped
• After the collision, both trucks moved together in the same direction at 10 m/s before slowly rolling
to a stop.
You must now push Truck 2, using 1,000 N of force, 8 meters off to the side of the road so no one
else gets hurt.
1. What was the potential energy of Truck 1 at the top of the hill? 2. What was the kinetic energy of each truck before the began braking? 3. A. How much energy did truck 1 lose from the top to the bottom of the hill? B. Where do you suppose that energy went?
Answer:
1) Kinetic energy of the truck 1 is 600,000 joules.
Kinetic energy of the truck 2 is 1,837,500 joules.
2 a)Potential energy of truck 1 is 646,800 Joules.
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.
Step-by-step explanation:
Mass of the truck 1 and truck 2,m = 3000 kg
Velocity of the truck 1, = = 20 m./s
Velocity of the truck 2, = 35 m./s
1. Kinetic energy of the truck 1:
Kinetic energy of the truck 2:
2.a) Energy loose by the truck 1:
Initial height of the truck on the hill = 22 m
At that height potential energy will be maximum:
Potential energy of truck 1 at that height =
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.

¿Qué tipo de célula apareció primero en la Tierra?:___, y se presentan en seres vivos como las:___ y se caracterizan porque:___. *
Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
