Find every angle of rotation that maps the figure onto itself.

Answers

Answer: Assuming the rectangle is not a square, a rotation of 180º, -180º, 360º, -360º will rotate the rectangle back onto itself.

If you want to consider angles beyond 360º, any rotation of k(180º) where k is an integer will work.

If you are looking at that special case of rectangle known as a square, any rotation of k(90º), where k is an integer will do the trick.

Leopards have spots to blend in with the patches of sunlight on the jungle floor.
How might a trait like spots become more common in a population of leopards?

A. Leopards get their spots by rubbing against each other. Eventually all leopards
in a population will have spots.

B. Blending in helps leopards successfully hunt for food. Leopards with more food
are more likely to survive and pass on their spotted trait to offspring.

C. An adult leopard develops more spots during its lifetime in order to compete
with other leopards.

Answers

Option B is the most likely to result in the increased prevalence of spots in a population of leopards. This is because natural selection favors traits that provide a survival advantage. In the case of leopards, having spots helps them blend in with their environment and become better hunters, which increases their chances of survival and reproduction. Over time, this can lead to the spotted trait becoming more common in the population, as individuals with the trait are more successful at passing it on to their offspring.

B is the correct answer. Adaptations that allow animals to survive in an environment are more favored and they will live to pass those traits onto their offspring

Why is expressed sequence tag library a fitting name for a collection of clones made from mRNA?
please help :((((

Answers

An expressed sequence tag (EST) library is a collection of short cDNA (complementary DNA) sequences that are generated from the mRNA (messenger RNA) of an organism. The name "expressed sequence tag" is fitting because these short sequences are "tags" that identify the expressed genes in a particular cell or tissue.

The term "expressed" refers to the fact that the mRNA is transcribed from a gene and has therefore been "expressed" or made into RNA. The term "sequence" refers to the fact that the cDNA sequences are determined by sequencing the mRNA. Finally, the term "tag" refers to the fact that the ESTs are short sequences that can be used to identify expressed genes in a particular cell or tissue.

Therefore, the name "expressed sequence tag library" is fitting for a collection of clones made from mRNA because it accurately describes the nature and function of the library.

Which of the following statements regarding lipid bilayer is true?
A. The lipid bilayer is flexible and are not able to bend.
B. The hydrophobic molecules are polar and form favorable interactions with water.
C. A typical membrane lipid molecule has a hydrophilic head and are amphoteric.
D. The membrane phospholipids are nonmotile.
E.
The most abundant lipids in cell membranes are phospholipids.

Answers

The true statement regarding lipid bilayer is E. The most abundant lipids in cell membranes are phospholipids. The lipid bilayer is made up of two layers of phospholipid molecules, with the hydrophilic heads facing outward and the hydrophobic tails facing inward. This structure provides a barrier that separates the inside of the cell from the outside environment, while also allowing for the selective transport of molecules across the membrane.

what is the basic concept behind relative age dating of fossils a the Upper Rock layers were deposited earlier in the Lower Rock layers b the Lower Rock layers were deposited earlier than the Upper Rock layers c the older fossils contain relatively higher levels of radioactive d the younger fossils contain relatively higher levels of radioactive isotopes in the older fossils ​

Answers

The basic concept behind relative age dating of fossils is that the Lower Rock layers were deposited earlier than the Upper Rock layers. This is because the principle of superposition states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are at the bottom, and the youngest rocks are at the top. As a result, fossils found in the lower layers are generally older than those found in the upper layers. This method of dating does not rely on measuring radioactive isotopes or other methods that require absolute dates, but rather on the relative position of the fossils within the layers of rock.

What combination of processes can transform a metamorphic rock to sediments?
a.
erosion, crystallization, and melting
b.
heating, pressure, and lithification
c.
melting, crystallization, and compaction
d.
exposure, weathering, and erosion

Answers

Option D Exposure, weathering, and erosion is the correct answer. It is the combination of processes that can transform a metamorphic rock into sediments.

Metamorphic rocks are shaped by the change of pre-existing rocks (molten, sedimentary, or other metamorphic rocks) through warm, pressure, and/or chemical forms. To convert a metamorphic rock to sediments, the rock ought to be uncovered to the surface and experience weathering and disintegration forms.

Exposure alludes to the method of bringing the transformative rock to the Earth's surface. This could happen through structural elevations, disintegration of overlying rocks, or volcanic action. Once the rock is uncovered, weathering processes break down the rock into littler parts or sediments. This may happen through physical or chemical weathering, such as the activity of water, wind, ice, or chemical responses with air or water.

Richard knows he's a take-charge kind of person. He is a good student, and knows it is because of his hard work. What type of attribution is he using, and why do you think this is?

Answers

Richard is using an internal attribution, as he attributes his success to his own abilities and efforts rather than external factors.

Attribution theory refers to the process by which individuals explain the causes of events and behaviors, including their own. Internal attribution refers to the explanation of behavior in terms of an individual's own abilities, traits, or efforts, while external attribution refers to the explanation of behavior in terms of situational or environmental factors. In the case of Richard, he is using an internal attribution by attributing his success as a good student to his own hard work and abilities, rather than to external factors such as luck or help from others.

This suggests that Richard has a strong sense of control and agency over his own life and achievements, and believes that he can influence the outcomes of his own actions through his efforts and skills. This type of attribution can be empowering and motivating, as it reinforces a sense of personal responsibility and ownership over one's life outcomes.

Answers

Answer:

Survive is the correct answer

Explanation:

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population

1.11 Graded Assignment: Discussion: Differentiating Among Newton's First, Second, and Third Laws
So you have to write what are the differences between newtons 3 laws and what they are

Answers

1. Newton's first law of motion projects that a object at rest will remain at rest, and a object in motion will remain in motion with a constant velocity, until or unless a force is acted upon by the external environment.

2. Newton's second law of motion projects that the acceleration of an object is considered to be directly proportional to the net force acting on the object and generally inversely proportional to its mass.

3. Newton's third law of motion projects that for every action, there is an equal and opposite reaction.

The first law is also renowned as the law of inertia. The second law thoroughly distinguishes the relationship between applied force and the rate of change of momentum. And finally the third law is also know as  the law of action and reaction because it depends on the type of stimulus that is experienced from the environment when the individual is applying force.
