A. A book about planning sexual activities
B. Scientific research on the body
C. The news paper
D. An age restricted site showing nudity
Answer:
B. Scientific research on the body
Explanation:
B is the most plausible answer because option A and D will not answer your research question about sexual hormones (from a scientific perspective) and option C will have information which will not help you make conclusions since newspaper take their information from other sources and sometimes leave out chunk of data or information to fit it in one page.
Therefore, best option is B to look into scientific research on body where you'll likely encounter research related to blood rushing and sexual hormomes.

Answer:
50 percent
Explanation:
The answer above is NOT correct.
I took the test on Edge and 50 percent is right!
According to the Punnett square for this cross,50% percentage of offspring is predicted to have blue feathers.
What is Punnett square ?The Punnett square is a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given.
How do you find the Punnett square?Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring.
Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.
Therefore, according to the Punnett square for this cross,50% percentage of offspring is predicted to have blue feathers.

what is the resistance of a car light bulb that conducts 0.025 A current when connected to a 12 V car accumulator? Is the current in the bulb steady?
Answer:
R = 480 Ohm
Yes, the current is steady since the power supply is a constant 12V (comming from the battery).
Explanation:
U=I*R
R = U / I
U = 12 V
I = 0.025 A
R = 12 / 0.025
R = 480 Ohm

Jordan's grandmother uses the juice from squeezed lemons to remove stains from his shirt. He hypothesizes that the juice is the only part of the lemon that is effective at removing the stains, because it’s an acid. Which two steps would help Jordan determine whether his hypothesis is scientifically supported?
Answer: I would say The hypothesis that the juice of the lemon is the only pat of lemon that is capable of removing stains from the t-shirt is because the lemon juice is acidic in nature.
1.) To test the validity of this hypothesis he should test the acidity of different parts of the lemon including the juice, pulp and skin of lemon.
2.) He should also compare the lemon juice with other juices to know weather other juices are also helpful in removing stains from the t-shirt.

A bat wing, an alligator leg, and a human arm are homologous structures.
Which fact about those structures best supports one aspect of theory of evolution?
The fact that the bone structures are similar supports the concept that birds evolved from mammals.
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
The fact that the bone structures are completely different supports the concept that those organisms shared a common ancestor.
Answer:
The fact that the bone structures are similar supports the concept that the animals shared a common ancestor.
Explanation:
The similarity of the wings of bats, legs of alligators, and arms of humans in structure is an indication that animals shared a common ancestor according to the evolution theory.
Homologous organs are organs found in different organisms that are similar in structure but different in functionality.
The fact that these organs are similar to each other in morphological structure points to the fact that they might have evolved from the same ancestor according to evolutionists.
The wings of bats, legs of alligators, and arms of humans are all based on the same pentadactyl (five-digit) structure. However, a bat uses its wing to fly, alligators use their legs to crawl, while humans use their arms for a variety of purposes.
The homologous organ is one of the pieces of evidence used to support the evolution theory.

Why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answer:
Read Explanation
Explanation:
Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope

define the general difference between an autotroph and a heterotroph
Answer:
Explanation:
If we break down the word autotroph, auto means “self” and troph means "feeding" or nourishment. However, when we break the word heterotroph, we get hetero- meaning other, and troph meaning feeders.
This is the critical difference between these two groups. Autotrophs synthesize or make their own food whereas, heterotrophs cannot make their own food thus have to rely on others by eating or absorbing others. For example, plants are autotrophs because they can make their own food using photosynthesis, whereas, humans are heterotrophs because we have to eat others to survive.
Answer:
autotrophs are organisms that can produce their own food from the substances around them using light or chemical energy
heterotrophs cannot synthesize their own food and rely on other organisms plants and animals for nutrition

The populations living on a rough, steep mountain would have a higher rate of
speciation than those living in a large, open grassland because the mountain
would
A. show less habitat fragmentation
B. provide its populations with more resources
C. isolate populations into subgroups
D. have fewer niches for organisms
Answer:
The correct answer is option C, that is, have a wider range of environments.
Explanation:
It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.
A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
In comparison to populations living in broad, open grasslands, populations living on rocky, steep mountains would experience a higher rate of speciation due to the mountain's ability to divide populations into smaller subgroups . So, the correct option is C.
How the population have higher rate of speciation?Geographic isolation is known to be a common way for the beginning of the process of speciation, similar to the formation of mountains, the alteration of rivers, the migration of organisms, and continental drift. As a result, what was once a stable population becomes divided into two or more different kinds of smaller populations.
A mountain range might result in a greater amount of speciation because to differences in precipitation and temperature as a result of various altitudes. A single mountain chain can display a huge variety of biodiversity and temperature zones as a result of these variances.
Therefore, the correct option is C.
