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.

The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.
Answers
Answer:
According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.
Explanation:
The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.
In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

Explanation:
Over the past 170 years, human activities have raised atmospheric concentrations of CO2 by 47% above pre-industrial levels found in 1850. This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm).
Michael loves playing his clarinet and believes it attracts more rabbits than any other instrument he
has played. In order to test his hypothesis, Michael played a song on his clarinet for a total of 5
minutes and counted the number of rabbits he saw in his front yard. He played the song a total of 3
times on his clarinet and repeated the experiment using a flute and a guitar. He also recorded the
number of rabbits he observed when he was not playing an instrument. The results are shown in the

1) What is the independent variable?
2) What is the dependent variable?
3) What is the experimental group?
4) What is the control group?
5) What is one constant from the experiment above??
Answers
Answer:
Independent variable: type of instrument
Dependent variable: Number of rabbits attracted
Experimental group: The group when he played an instrument
Control group: The group when not playing an instrument
Constant: Same song
Explanation:
1. Independent variable is the variable that the experimenter changes or manipulates in an experiment. In this experiment, the variable that is changed is the TYPE OF INSTRUMENT used (clarinet, flute, guitar), hence, it is the independent variable.
2. Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the "NUMBER OF RABBITS ATTRACTED" by the instrument played.
3. Experimental group is the group of an experiment that receives experiment treatment, which is the independent variable. In this case, the experimental group is the GROUP IN WHICH INSTRUMENT WAS PLAYED.
4. Control group is the group that does not receive the experimental treatment. In this case, the control group is the group in which INSTRUMENT WAS NOT PLAYED.
5. Constants are those variables that remains unchanged for all groups throughout the experiment. In this case, one constant is the SAME SONG played.

Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
these twins look so different even though they have the same parents. Why aren't they identical? In
your answer you should include your knowledge of gametes (sperm and egg), chromosomes, and
variation
Answers
Answer:
Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.
I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

Explanation:
The process of transcription occurs inside the nucleus of the cell in the eukaryotic cell typically not in prokaryotic cell whereas the translation process occurs in the cytoplasm with the help of ribosome.
mRNA is the product of transcription whereas the polypeptide chain of amino acids is the production of the translation in which further forms the protein.

C.Geologists will measure how stable multiple parent elements can decay into multiple daughter elements.
D.Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Answers
Answer:
D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.
Explanation:
Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.

An example of __ is the color of betta fish. When a RED fish (GG) is crossed with a YELLOW fish (gg), all of the offspring will be a ORANGE color (Gg)
Answers
Answer:
The correct answer is - incomplete dominance.
Explanation:
In the betta fish, there are different types of colors found in the fishes depends on the alleles present in their gene which follows incomplete dominance. Incomplete dominance is an inheritance pattern where a dominant allele does not mask completely and produce a blend of both alleles if present in heterozygous condition.
In the question, It is stated that when a cross between RED fish (GG) and a YELLOW fish (gg) produce orange color fish as offspring (Gg) which is a mix or blend of both alleles Red (dominant) and yellow (recessive).

When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this
description, in which two ways is energy conserved when people run?
-Heat energy is released from the body to the surroundings.
-Heat energy is taken from the surroundings to the body.
-Chemical energy is converted to mechanical energy that's used for muscle movements.
-Radiant energy is converted to mechanical energy that's used for muscle movements.
-Heat energy is converted to mechanical energy that's used for muscle movements.
Answers
Heat energy is released from the body to the surroundings and Chemical energy is converted to mechanical energy that's used for muscle movements are the two ways in which energy is conserved when people run.
To do the things you do every day, you need energy. When you eat food, your body can use the chemical energy in the food to move your muscles, allowing you to breathe, walk, run, jump, lift things, and do everything else necessary for survival.
The chemical energy in food is converted into mechanical energy by moving muscles.
Chemical energy in the form of glucose in our food is converted into mechanical energy in the human body during movements such as running or lifting heavy objects. The muscles act as a transducer, converting chemical energy to mechanical energy through muscle contraction.
