What happens during interphase?
A.The chromosomes are duplicated.
B. Tetrads are pulled apart.
C. The spindles attach you chromatids.
D. Two haploid gametes are formed.
Answers
Explanation:
During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotoc phase. During that phrase, the duplicated chromosomes are segregated and distributed into daughter nuclei.
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.

Explain how the Coriolis effect influences the wind direction in your model.
Answers
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.

The equation of line e is y = 3/5x + 1. The equation of line f is y = -8/3x + 9/8. Are line e and
line f parallel or perpendicular?
Answers
Answer:
I think they're neither perpendicular nor parallel
Explanation:
Not parallel since slope of e (3/5) isn't equal to slope of f (-8/3)
Not perpendicular since the product of their slopes isn't equal to - 1.
=> (3/5)(-8/3)= - 8/5 and not - 1

What stage of meiosis is shown below?
A. Anaphase
B. Telophase II
C. Telophase
D. Anaphase II
Answers
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.

why do waves that travel through basalt have a higher velocity than a wave traveling through sand?
Answers
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.

b) releases 2260 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-
Answers
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.

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.

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.
