How are chromosomes arranged in a karyotype?
Answers
Answer: A karyotype test examines these dividing cells. The pairs of chromosomes are arranged by their size and appearance.
Explanation:
In a karyotype, the arrangement of chromosomes is generally done in the order of size, that is, from largest to smallest.
What is a karyotype?It is the number and appearance of chromosomes. It comprises the length of the chromosomes, the banding pattern, and the position of centromere.
In a human karyotype, the body chromosomes or autosomes are usually aligned in approximate order of size from largest to smallest, that is, from chromosome 1 to chromosome 22.
However, the chromosome 21 is shorter in comparison to chromosome 22. The arms of the chromosomes protruding from either end of the centromere may be classified as long or short, based upon their relative lengths.
The long arm is abbreviated as q and the short arm as p. Each arm is subdivided further and is designated by a number. The locations on chromosomes can be illustrated by using the naming system.
Thus, in a karyotype, chromosomes are arranged on the basis of their size, that is, from largest to smallest.

Joe is experimenting to determine which liquid will cause bean plants to grow faster. He watered the plants with equal amounts of liquid and measured their height every other day. The plants are in the same pots with different soils and placed in the same location. Will Joe be able to obtain reliable data to write a supported conclusion?
Yes, because he is only observing the height of the plant.
Yes, because he is consistent with watering the plants.
No, because he used different soils.
No, because he uses only one type of plant.

He watered the plants with equal amounts of liquid and measured their height every other day.
The plants are in the same pots with different soils and placed in the same location.
Ok so last statement made the experiment wrong.
As a constant variable the soil should be the same for all plants only the liquid should change
What are the three main classifications that describe galaxies? By what one visible
characteristic do scientists categorize galaxies?
Answers
Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.

Water that falls onto land surfaces is either soaked into the ground or flows downhill into a body of water. The water that soaks into the ground is called groundwater.
Soil and rock that allow this water to pass through them are called ________.
A. aquifers
B. compacted
C. permeable
D. runoff
Answers
C. Permeable
The capacity of a rock or other substance to let the passage of water is known as permeability, hence option c is correct.
What is groundwater?Groundwater may readily flow through permeable materials because the pore space is linked throughout the rock or sediment. Mud and clay are examples of materials with great porosity yet very limited permeability.
An aquifer is a water-bearing rock that easily transfers water to wells and springs, the aquifers may be dug into and water pumped out.
Therefore, water that falls onto land surfaces flows into water bodies or it may be soaked in the ground, this water flows through the soil and rock which are permeable, hence option c is correct.

The axolotl, Ambystoma mexicanum, also known as the Mexican walking fish, is a neotenic salamander related to the tiger salamander. Although colloquially known as a "walking fish", the axolotl is not a fish but an amphibian. The species was originally found in several lakes, such as Lake Xochimilco underlying Mexico City. Axolotls are unusual among amphibians in that they reach adulthood without undergoing metamorphosis. Instead of developing lungs and taking to the land, adults remain aquatic and gilled.

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate
Answers
Answer:
120 joule.
Explanation:
Given
For the stone X
Mass (m) = 2 kg
Height (h) = 2 m
Acceleration due to gravity (g) = 10 m/s²
Then we have the formula to calculate the potential energy
P.E 1 = mgh
= 2 * 10*2
= 40 joule
Now for Stone Y
mass (m) = 4 kg
height (h) = 4 m
acceleration due to gravity (g) = 10 m/s²
Now
P. E2 = mgh
= 4 * 10* 4
= 160 joule
Now the difference between their potential energy is
= P. E2 - P. E 1
= 160-40
= 120 joule

scientists can determine the evolutionary relationships between different organisms by comparing their appearances, figure, and body internal and external structures.

Scientists utilize DNA to evaluate evolutionary relationships, along with resemblance in early development and bone structure.
What are evolutionary relationships?Organisms with similar physical characteristics and genetic sequences are more strongly linked than those that do not.
Homologous structures are components that overlap both anatomically and genetically; the similarities stem from shared evolutionary paths.
Thus, scientists utilize DNA to evaluate evolutionary relationships, along with resemblance in early development and bone structure.
