how does Pteromyzon differ from scolidon and labeo fishes?
who answer this question in 10 seconds I'll mark his or her ans. as "BRAINLIST ANSWER"
It's my promise but the answer must not be copied from internet
Answer:
Due to agnathous, no paired fins and scales.
Explanation:
Pteromyzon fish is different from scolidon and labeo fishes because Pteromyzon fish is not a true fish. The main reason for this is that Pteromyzon fish is agnathous means having no jaws and it doesn't have paired fins and scales on their body while all these features are present on the body of scolidon and labeo fishes so we can conclude from this discussion that Pteromyzon fish is different from scolidon and labeo fishes.

If there is no teacher present, she should wash her hands and arms twice to remove as much of the chemical as possible. Then she should call a poison help or chemical help center if she is unsure of what to do next.

The diagram below compares the relative diameters of two planets in our solar system.
Which two planets have diameters that most closely resemble this comparison?
1.
Uranus and Neptune
2.
Jupiter and Saturn
3
Earth and Mars
4.
Mercury and Venus
Submit Answer
Answer:
1, uranus and neptune
Explanation:
i just did it
Based on the diagram above, the two planets having diameters that most closely resemble this comparison are: 1. Uranus and Neptune.
A solar system is an astronomical system which comprises both the inner and outer planets alongside celestial bodies such as a Moon, that are typically in orbit (traveling) around the Sun in slightly elliptical orbits..
Basically, the nine (9) planets that are found in the solar system orbiting around the sun include;
Mercury. Venus. Earth. Mars.Jupiter.Saturn.Uranus.Neptune.Pluto.Generally, the planets found in the solar system vary considerably in terms of shape and size as shown below:
1. Uranus and Neptune: the mean diameter of Uranus is 50,724 km (31,518.43 mi) while that of Neptune is 49,244 km (30598.8 mi).
2. Jupiter and Saturn: the mean diameter of Jupiter is 142,984 km (88,846 mi) while that of Saturn is 120,536 km (74897.6 mi).
3. Earth and Mars: the mean diameter of Earth is 12,756 km (7926 mi) while that of Mars is 6779 km (4212.275 mi).
4. Mercury and Venus: the mean diameter of Mercury is 4,879 km (3031.67 mi) while that of Venus is 12,104 km (7521 mi).
From the above data on diameter, we can deduce that both Uranus and Neptune are mostly related in terms of size as depicted in the diagram, by using two (2) circles of equal sizes.

Two offspring from same parents can have different phenotypes. How is this possible?
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
Explanation:
Overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.
What is heterozygote?Heterozygote is defined as a person, animal, or other thing possessing a pair of different alleles of a specific gene, one of which is dominant and the other recessive. One normal allele and one mutated allele, or two distinct mutated alleles, can make up a heterozygous genotype.
The explanation is connected to the fact that each parent has two different gene pools. Furthermore, only 50 percent of each parent's DNA is transferred to their offspring. and that the portion that is passed down is random. Every child has a unique set of genes thanks to the interaction of all these influences.
Thus, overdominance, in instance, happens when a heterozygote exhibits a more extreme phenotype than either of its parents.

Philippe did some research about classification for a science report. He learned that until 160 years ago, scientists recognized only two groups of microscopic organisms. How should Philippe explain why scientists decided to classify organisms into more groups?
More types of organisms exist now.
Fewer organisms have gone extinct in recent years.
Scientists invent new organisms that need to be classified.
Scientists continue to learn more about living things.
Answer:
The correct answer would be - Scientists continue to learn more about living things.
Explanation:
In past scientists continues to do various research, findings, studies and experiments regarding diferent type of living organisms and their components and body parts.
These research, studies, and many other aspects of the science helps scientists to conotinue to learn more about living things which helps in provide information that there are different type of organism and should be classified.

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??
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.
