Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.

Explain how the Coriolis effect influences the wind direction in your model.
Answer:
Coriolis effect influences the wind direction.
The Coriolis effect makes the wind to appear and be deflected to either the east or west depending on the direction the wind is moving in either the north or southern hemisphere.
The Coriolis effect makes wind on the northern hemisphere to curve to the right by bending it to counter clockwise direction and that of southern hemisphere curve to the left.
Explanation:
Coriolis effect refers to the pattern of deflection of object in which the northern hemisphere bend to counter clockwise direction and the southern hemisphere to the left.
Coriolis effect is caused by the Earth's rotation.
Answer:
This is the exact answer so maybe re-word it:
If Earth did not rotate, the winds would appear to flow in a straight path. However, because of Earth’s rotation, the winds appear to bend to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Right and left are relative to the wind’s starting location.

why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answer:
Hope i helped!
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
The waves that travel through basalt have a higher velocity than a wave traveling through sand as the 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.

eronica wrote Charles Darwin’s main points on the board, but she made a mistake in one point.
1. Since more offspring are produced than an environment can support, organisms within a population must compete for resources to survive.
2. Due to variations within the population, some competitors will be better equipped for survival than others.
3. The best-equipped organisms will survive and will produce well-equipped offspring.
4. Variations that help with survival will be passed on to future generations and will rapidly change the whole population.
Which point is flawed as written above?
point 1
point 2
point 3
point 4
Answer:
Point 4
Variations that help with survival will be passed on to future generations and will rapidly change the whole population.
Explanation:
Charles Darwin formulated that the principal basis of evolution is the natural selection. Natural selection is a mechanism by which signifies the relation between adaptation of the species to their environment and their survival. Darwin's Theory of Evolution's four main points are: members of a species are not identical, more offspring are born than they can survive, traits are transferred from one generation to other, and only the winners of the resource rivalry are reproducing. But rapid change of the population was not suggested by him.

please please helppp meee A mammalogist is studying the behavior of the rain forest jaguar. She spots a jaguar
crouched on a tree branch in the understory, waiting to pounce on a rain forest herbivore
called a tapir. The hair of the jaguar is white with black spots. The jaguar has learned the
habits of this tapir, and he knows it uses this trail each evening. The cat is panting in the
steamy heat to stay cool, and its muscles tense as the tapir approaches. The jaguar pounces
and stabs its prey with long, sharp incisors. Although its meal is large, it will need to hunt
and eat again in a day or two to ward off its hunger.
Compose a four-to five-sentence paragraph that summarizes the general mammal
characteristics you can identify from the details of the story about the jaguar.
Answer:
The rainforest jaguar, exhibits a well-known mammal characteristic, as it waits for its opportunity to pounce on its prey. Mammals are known to be dominant in its environment, actively seeking its targets. Furthermore, the hairs on the jaguar would be an indicator of its status as a mammal. As mammals are known to have hair, and it is thus a mammal characteristic. They are known to be warm blooded, and one instance in the passage that hints at the jaguar's warm bloodedness would be when it pants in order to stay cool.
Note:
this is really vague lol, since I don't know your teacher's lesson plan, so I'm not sure what mammal characteristics are pointing towards (biological, or behavioral?) so note that this response might not be what your teacher is looking for.

b) releases 2260 J/g of heat energy
c) gains 334 J/g of heat energy
d) gains 2260 J/g of heat energy
I've narrowed it down to a or b, but I wrote the whole question in case I'm wrong-
Answer:
I actually got releases 2260 J/g of heat energy.
Explanation:
you can determine this by the earth science reference table on the first page , and plus I have the same question.
The process through which the water vapour gets converted into liquid is called condensation. It happens either because of cool air or saturation.
The correct option is:
Option b. releases 2260 J/g of heat energy
This can be explained as:
The amount of heat required for converting 1 mole of liquid into the gaseous state at atmospheric pressure is called the latent heat of vaporization.The amount of heat released from a mole of vapour when condensed to liquid is called the latent heat of condensation.During this process, the temperature remains constant and the heat released gets used in the conversion of substance and is called latent.Therefore, the heat of condensation of water vapour is about 2,260 J/g.

What stage of meiosis is shown below?
A. Anaphase
B. Telophase II
C. Telophase
D. Anaphase II
Answer:d
Explanation:
In meiosis II, each single chromatid moves to the opposite pole. The cell present in the diagram is in the anaphase II stage. Hence, the correct option is option D.
What is meiosis?
Meiosis is a cell division in which four haploid daughter cells (n) are formed from a parent cell. This process completes in two phases, such as meiosis I and meiosis II. In meiosis I, there are prophase I, metaphase I, anaphase I, telophase I, and cytokinesis. In meiosis I, homologous chromosomes separate. At the end of meiosis I, two haploid cells (n) are formed.
These two haploid cells enter meiosis II. Meiosis II includes prophase II, metaphase II, anaphase II, telophase II, and cytokinesis. In prophase II, chromosomes constrict and shorten. In metaphase II, chromosomes align on a plane and attach to spindle fiber. In anaphase II, duplicated chromosome separates and starts to move towards the opposite pole. In telophase II, these chromosomes get closer to the poles, and cytokinesis starts.
Hence, anaphase II is the correct answer as daughter chromatids start to separate. option D is the correct.

B. Sympathetic helps the body gain and conserve energy: parasympathetic prepares the body to react.
C. Sympathetic allows the body to relax; parasympathetic helps the
body achieve tension.
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Answer:
D. Sympathetic prepares the body to react; parasympathetic helps the body gain and conserve energy.
Explanation:
the sympathetic system is your fight or flight response
parasympathetic system is the rest and digest
The statement, that is, the sympathetic prepares the body to react, and parasympathetic helps the body to conserve and gain energy correctly describes the functions of parasympathetic and sympathetic nervous system.
What are the functions of parasympathetic and sympathetic nervous system?Both the parasympathetic and sympathetic nervous system are the components of the autonomic nervous system. The sympathetic nervous system is situated close to the lumbar and the thoracic regions in the spinal cord.
Its main role is to instigate the body's flight or fight response. It does this by monitoring the rate of respiration and the rate of the heart. Therefore, it prepares the body to react.
On the other hand, parasympathetic nervous system is situated in between the medulla and the spinal cord, and works to stimulate the body's digest and rest and breed and feed response. Therefore, it helps the body to conserve and gain energy.
Thus, the correct statement is option D.

A.The chromosomes are duplicated.
B. Tetrads are pulled apart.
C. The spindles attach you chromatids.
D. Two haploid gametes are formed.
Chromosome duplication is the process that occurs during interphase. The correct option is A.
What is interphase?The interphase stage of the cell cycle is where the majority of the life of a typical cell occurs.
Interphase is the cell's "daily living" or metabolic phase, during which it acquires and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Thus, the correct option is A.
