What statement is true regarding active transport
Answer:
Substances can move from areas of low concentration to high concentration.
Explanation:
For the first one, substances CAN move in and out of cells in an active transport.
As for the second one, active transports do require energy. That is what makes them "active" and sets them apart from passive transports which don't require energy.
Lastly, substances can move across a membrane regardless of if they are water soluble (such as lipids, or fats that the cell does not use. Think of it as a way for the cell to eat, drink, and defecate or remove waste.)
Why is the sky blue? I know it’s a generic question but I honestly don’t know
Answer:
As sunlight passes through the atmosphere, particles in the air scatter blue light more efficiently than any other color in the light spectrum, creating a blue sky.
Explanation:
given the following DNA strand which of the following is it’s complementary MRNA? GGACTGATT
A. C C U G A C U A A
B. C C T G A C T A A
C. G G A C T G A T T
D. T T A G T C A G G
The following DNA strand "GGACTGATT" has the complementary mRNA strand "CCUGACUAA". Thus, the correct option is A.
What is mRNA?An mRNA is a type of RNA which is found inside cells. mRNA is also known as messenger RNA. The mRNA molecules carry genetic information which is required to make proteins in the cell. They carry the information from DNA in the nucleus of the cell to the cytoplasm where the proteins are synthesized.
The mRNA synthesized complementary to the sequence of DNA strand can be determined. As A base pairs with U and vice versa and C base pairs with G and vice versa. Thus, the sequence of mRNA synthesized from the DNA sequence "GGACTGATT" will be "CCUGACUAA".
Therefore, the correct option is A.

Describe the path that air takes as it enters and passes through the human respiratory system
Answer: The pathway of air in the respiratory system starts with the external organs of the nose and mouth. Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.

If the herbivore population in an ecosystem increased what would most likely happen to the size of the carnivore population
Answer:
the carnivore population(s) would increase because their amount of food would increase also
Explanation:
Answer:
Possibly increase
Explanation:
Since there would be an increase of the herbivore population, the carnivores would have more to eat providing more food for their young.
2. Compared to many other liquids, water has a high heat of vaporization, which means a relatively large amount
of heat must be added to the water before the water molecules are moving fast enough to escape the surface as a
gas, Which of the following explains why water has a high heat of vaporization?
A. Adding heat to the water causes the molecules to move around, and the motion keeps pushing
them back below the water's surface.
B. As water molecules heat up they tend to form more hydrogen bonds with each other, making it
difficult for any of the molecules to vaporize.
C. Water molecules have a relatively high molecular weight compared to other molecules, so more
energy is needed for the water molecules to vaporize.
D. Enough heat must be added to water molecules' hydrogen bonds to break the bonds and provide
the molecules enough energy to escape the surface.

Find the acceleration if the change in velocity is 5 m/s and the time is 10 seconds
Answer:
i think that
Explanation:
solution
given
velocity (v) = 5m/s
time(t) = 10 sec
acceleration (a) = ?
By using formula,
a = v÷t
a= 5÷10
a = 2m/sec
Answer:
0.5 m/s
Explanation:
acceleration (a) = speed (s) / time (t)
a = 5/10
How much energy is transferred up through the trophic levels from primary producer to
primary consumer?
Answer:
On average, only about 10% of the energy stored as biomass in one trophic level—e.g., primary producers—gets stored as biomass in the next trophic level—e.g., primary consumers. Put another way, net productivity usually drops by a factor of ten from one trophic level to the next.How are embryonic stem cells different from other types of stem cells?
The difference between embryonic stem cell and other types of stem cells are :
Embryonic stem cell replicate indefinitely Embryonic stem cell is pluripotentThere are about 200 different types of cells present in the human body and the embryonic stem cell is different from other adult cells because it has the ability to differentiate into the ( 3 ) primary germ layers ( i.e. pluripotency ) and also they can replicate indefinitely unlike other cells that can only replicate itself a limited number of times.
Hence we can conclude that the difference between embryonic stem cell and other types of stem cell are Embryonic stem cell replicate indefinitely and Embryonic stem cells are pluripotent.

This model of the cell cycle includes two arrows that each represent a process in the cycle.
Arrow 2
G, phase
Arrow 1
s phase
G phase
What do the two arrows represent?
F Arrow 1 represents prophase, and Arrow 2 represents interphase.
Arrow 1 represents mitosis, and Arrow 2 represents meiosis.
H
Arrow 1 represents interphase, and Arrow 2 represents mitosis.
J Arrow 1 represents meiosis, and Arrow 2 represents prophase.
Answer:
Arrow 1 represents interphase and arrow 2 represents mitosis
Explanation:
The cell cycle is generally divided into two phases:
the interphase, andthe M or mitotic phaseThe interphase represents the period between the telophase of one cell division and the metaphase of another. This is the period the cell uses to prepare itself for active division. It takes up a large chunk of the cell cycle and it is further divided into:
the G1 phase which represents the period of cell growth and increase in volume,the S phase which represents the period during which DNA is synthesized, andthe G2 phase which represents the period during which protein is synthesized.The mitotic phase represents the period of active division. It is further divided into the prophase, the metaphase, the anaphase, and the telophase.
Hence, the first arrow (1) of the model represents the interphase while the second arrow (2) represents the mitotic phase.
Answer: arrow 1 represents interphase and arrow 2 represents mitosis.

How would you expand this model to include the effects of fishing on this population?
Chose ALL the choices that are true about exponential growth: a Rapid (fast) period of growth b Has carrying capacity c "S" curve d "J" curve e Takes place when there are lots of resources ex: food, space f Takes place when there are limited resources ex: food, space
Answer:
a, d, and e
Explanation:
The exponential growth is a period characterized by rapid growth as a result of the availability of unlimited resources for the use of the population. Once the population spends a short period getting acclimatized to their environment, a period of rapid growth follows that is devoid of any limitation and thus, the growth curve forms a 'J' shape. This type of growth has no carrying capacity that limits its growth and may not be possible in real life where resources are limited.
The correct options are a, d, and e.

Whats the difference between bacteria cells, and blood cells?
Answer:
recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.
While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.
