Answer:
it should be natural selection but im not too sure...
Explanation:
Answer:
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species.

____ pathways include all the pathways that bring information ____
and spinal cord ____ the effector muscles and glands
the brain
A. Efferent; to; from
B. Afferent; to; from
c. Efferent; from; to
D. Afferent from; to
E. None of the above
Answer: B. Afferent; to; from
Afferent pathways include all the pathways that bring information to the brain and spinal cord from the effector muscles and glands.
Explanation:
Afferent signals come from outside stimuli and tell your brain what they are sensing, such as temperature.
Efferent pathways carries signals away from the central nervous system which includes the brain and spinal cords. There are signals that your brain sends to tell your body to do something, like blinking.
How the musculoskeletal and nervous system develop as a human grows
Answer:
(look at explanation)
Explanation:
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "
Answer:
... areas labeled both red and green.
Explanation:
The spots that show up as yellow correspond to areas labeled both red and green.
__
The effect of combining images will depend on the method used to create the combination. There are many possibilities when combining color images.
When mixing red and green light, yellow light is produced. When mixing red and green pigment, brown pigment is produced. When mixing digital representations of red and green, the effect depends on the individual representations, the method of mixing, and the interpretation of the mixed result.
__
Given the way the question is worded, we assume that yellow is produced by a combination of red and green appearing in the same area of the images. That is, ...
The spots that show up as yellow correspond to areas labeled both red and green.

Biologists notice that a population of ferrets introduced into a reserve begins to show exponential growth. The figures represent the population of the ferrets for the first four years after their introduction. Which set of figures represents the exponential growth of the ferrets? A. 50, 88, 145, 227 B. 50, 92, 90, 95 C. 50, 32, 17, 9 D. 50, 95, 59, 97
Answer:
A. 50, 88, 145, 227
Explanation:
The correct option would be option A.
When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.
In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.

Which type of reproduction involves the passing of characteristics to offspring? A. only sexual
B. only asexual
C. both sexual and asexual
D. neither sexual or asexual
Answer:
C. both sexual and asexual
Explanation:
In both cases, the parent(s) of the offspring pass down characteristics. Asexual reproduction makes a carbon copy of the parent so they would obviously have the parent's characteristics. Sexual reproduction passes down characteristics of both parents to the offspring.
true or false: the momentum is moving planets does not depend on their masses
This is false, because plants have angular momentum, which is found by the formula (mass x velocity x distance). Therefore, mass is an important factor in a planet's momentum.

What is the danger of combining foods?
Answer:
There could be chemical reactions like indigestion, fermentation, putrefaction and gas formation and, if prolonged, can lead to toxemia and disease.
Explanation:
Answer:
Bad food combinations can lead to stomach ache, bloating, fatigue, gas, and discomfort. If you continue consuming the wrong food combinations for a long period, it can result in rashes, chronic digestion problems, and bad breath.

Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.
Explanation:
Describe the microscopic structures you would expect to see in the lungs.
Answer:
Alveoli
Explain:
They are the workhorses of your respiratory system. You have about 480 million alveoli, located at the end of bronchial tubes. When you breathe in, the alveoli expand to take in oxygen. When you breathe out, the alveoli shrink to expel carbon dioxide.
What is an example of a direct economic value of biodiversity? *
O release of oxygen by green plants
O diseases caused by bacteria
O vaccines created from bacteria
O drinking water provided by watersheds
Answer: release of oxygen by green plants

why is the moon white
Moonlight is no longer thought of as the cause. In the 16th century, moonmilk, a soft white limestone precipitate found in caves, was thought to be caused by the rays of the Moon.
Answer:
The moon is not actually white, it's grey.
Explanation:
What I learned is that what makes it white is the reflection of the sun and the sun makes it glow, that's why it looks white.
And if you focus on the moon when it's not full you'll see the other part of it showing but it looks grey not white, because as I told you it's the suns reflection.

Histones are 8 subunit proteins that cells use to pack DNA into the manageable condensed chromosomes you are used to seeing during mitosis or meiosis (functioning somewhat like hair rollers for DNA). Under normal circumstances, DNA binds TIGHTLY to histones. Given what you know about DNA structure, predict which amino acids are concentrated on the outer surface of histones that interacts with the backbone of DNA?
Answer: Arginine and Lysine
Explanation:
Histones are protein that packs DNA into nucleosomes. It compose of Arginine and Lysine amino acids.
Lysine and Arginine are basic amino acids that aids the solubility of Histone in water and also aids the interaction of DNA and Histones.
The amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).
In eukaryotic cells, Deoxyribonucleic acid (DNA) is tightly packed by its interaction with histone proteins. A nucleosome is the functional and structural unit of eukaryotic chromatin, which is composed of an octamer of histone proteins (two subunits of H2A, H2B, H3 and H4 histone proteins) and approximately 147 base pairs of DNA.The phosphate backbone of the DNA double helix is negatively charged because phosphate bonds between phosphorous atoms and oxygen atoms have a negative charge.In consequence, the tight wrapping of DNA around histones is due to the attraction between the phosphate backbone of the DNA molecule and positively charged amino acids of histones.In conclusion, the amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).
