Answer:
1.49 m/s; 5.367 × 10⁶ m/hr
Explanation:
Calculations: (This was my thought process, sorry)
386400 km ÷ 72 hr ≈ 5367
5367 × 1000 = 5.367 × 10⁶
5.367 × 10⁶ ÷ 3600 ≈ 1.49 m/s
About 5367 km/hr or 5.367 × 10⁶ m/hr or 2.592 × 10⁵ m/s

the concentration of solute outside of the cell are_____than the inside of the cell
What happens to a cell in a hypertonic solution
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.

Question 9 (1 point)
In peas, long stem (A) is dominant over short stem (a). A heterozygous, long stem plant (Aa) is crossed with a homo-zygous, short stemmed plant (aa).
Which of the above squares represent plants that are heterozygous?
Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3
Answer:
Box 1 and 3
Explanation:
Box 1 represents the allele Aa
Box 2 represents the allele aa
Box 3 represents the allele Aa
Box 4 represents the allele aa
So the answer is Box 1 and 3 because Aa is a heterozygous allele and aa is a homo-zygous allele.
A cross among individuals with contrasting variations at one locus for the attribute is called a monohybrid cross. Each parent provides one type of allele or a trait to their offspring.
Monohybrid cross can be shown using the Punnett square, to determine the probability of a progeny expressing that genotype.
The correct answer is :
Option C. Box 1 and box 3
The reason for the answer is:
1. Box 1 will produce offspring with genotype: Aa
2. Box 2 will produce offspring with genotype: aa
3. Box 3 will produce offspring with genotype: Aa
4. Box 4 will produce offspring with genotype: aa
Therefore, Box 1 and Box 3 represents heterozygous alleles, whereas box 2 and box 4 represents purebred alleles.

A. range = 5, median = 9
B. range = 5, median = 14
C. range = 15, median = 9
D. range = 15, median = 14
Answer:
c
Explanation:
The answer is c
Range and median of this data set 16, 10, 24, 12, 9, 14, 11, 14, 21When a list of numbers is arranged from smallest to largest, the median is the middle number, hence option C is correct.
What are the range and median?
The median of these outcomes. The range, in this case, is, where the range is the difference between the lowest and highest values.
Take the sum of all the numbers and divide it by the total number of numbers in the list to get the value of the mean.
Calculate the mean by adding up the center values and dividing them by two in order to determine the median.
Therefore, 16, 10, 24, 12, 9, 14, 11, 14, and 21 in the data set range are equal to the highest number minus the lowest value, hence option C is correct.

If the DNA is: TAC CGA CCG ACC TTA. Create a mRNA strand with a point mutation that would “not affect” the protein.
Answer:
AUG GCU GGG AGG AAU
Explanation:
A point mutation that would not affect the protein is one that has the same mRNA codon. The answer choices indicate that the third part is affected. The normal mRNA would be GGC, which if you look at the table, is gly. The other sequences that match are GGU, GGC, GGA, and GGG. The only answer choice that matches is the third one, with GGG.

Answer:
6400 years
Explanation:
Given that;
N/No =(1/2)^t/t1/2
No = amount of radioactive material originally present
N = amount of radioactive material present at time t
t= time taken for N amount of radioactive material to remain
t1/2 = have life of the radioactive material
2.5/40 = (1/2)^t/1600
1/16 = (1/2)^t/1600
(1/2)^4 = (1/2)^t/1600
4 = t/1600
t = 4 * 1600
t = 6400 years

Explain how the parts of the peripheral nervous
system work with the central nervous system to
produce a response to the stimulus
Answer: receptors in the skin stimulate sensory neurons
Sensory neurons send messages to the central nervous system
Interneurons send messages to the motor neurons in response to messages received from sensory neurons
Motor neurons cause muscles in the leg to contract and pull the foot away
Explanation:
To produce a response to the stimulus, receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment and from inside your body.
How peripheral nervous system works with the CNS?To produce a response to the stimulus the central nervous system processes information, it is the information that is received from the peripheral nervous system.
After that, the central nervous system sends this processed information to the peripheral nervous system. The peripheral nervous system sends a signal to the body part that needs to respond so you can react appropriately to the stimulus.
Therefore, if you accidentally step on a sharp object with your bare foot the peripheral nervous system work with the central nervous system to produce a response to the stimulus through receptors.

b. cooler than usual waters in the tropical Pacific
c. warm waters traveling eastward toward South America
d. cool waters causing colder than normal temperatures in the Southeast Incorrect
Answer:
D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
