the nucleic acids are packed with histones, which is proteinous, and contain nitrogen too
3. Myth: Tigers and goldfish are not related. o Fact: Tigers and goldfish are related. o Evidence:
Answer:
The correct answer is - Tigers and goldfish are both vertebrates. Vertebrates are animals that have spines and internal bone structures.
Explanation:
Tigers and goldfish belong to the same phylum but different Classes that suggests that they both are not very closely related but have some similarities and related.
Dorsal neural tube, a bilateral symmetry, a notochord, circulatory system, are some of the features that are shared by both organisms. These characters confirm that these two organisms are related.

Which statement best describes codominance and incomplete dominance?
Answer:
This question lacks options, the options are;
A) In codominance and incomplete dominance, both of the alleles are dominant.
B) In codominance and incomplete dominance, neither of the alleles are dominant.
C) In codominance, both of the alleles are dominant; in incomplete dominance, neither of the alleles is dominant.
D) In codominance, neither of the alleles is dominant; in incomplete dominance, both of the alleles are dominant.
The answer is C
Explanation:
Codominance and incomplete dominance are both a type of non-mendelian inheritance pattern i.e. patterns of inheritance that do not follow mendelian principles.
- In codominance, the alleles of a gene are both dominant and hence, both express themselves simultaneously for that trait. An example is the alleles A and B of the blood group in humans where both A and B are dominant in the gene.
- In incomplete dominance, neither of the two alleles of gene is dominant and none is recessive either. This means that the two alleles blend together to form an intermediate phenotype in a heterozygous offspring. An example is the pink flower in four o'clock plants resulting from the blending of red and white alleles.
Answer:
The correct answer is b
characteristics that scientists study to determine if a new species has been
discovered
Answer:
When ecologists travel to regions where they are not familiar with the plants and animals, they read field guides about the flora and fauna. Many of these guides have photographs, keys to species recognition, and descriptions of size, color, and general appearance.

This image shows the relative frequency of banded and non-banded snails in a population. If the frequency of banded snails decreased to 60% and non-banded snails increased to 40%, would you consider the population to be evolving?
Answer:
The nonbanded are evolving and the banded are not. It looks like something is either eating the banded shrimp and not the unbranded. Or the unbranded shrimp are eating the banded shrimp.
Explanation:
Hope this helps
As per the image of the single-gene trait the phenotypes are shown as per those with and without bands. The phenotypes without band are 20% and that of with band is 80%.
If the population of the snails gets reduced by 60% and non-banded gets 40% then the population that evolves would be that of the nonbranded snails will increase.Learn more about the relative frequency of banded.

why is water molecule called polar
Answer:
Since oxygen has a higher electronegativity than hydrogen, the electrons of the molecule tend to group closer to the oxygen than to the hydrogen atoms. as well as , water is said to be a "polar" molecule, which means that there is an uneven distribution of electron density.

A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.
Explain what would happen to the number of rats if the eagles died from a disease.
Answer:
If eagles died of disease, the number of snakes that prey on rats will increase, which will decrease the number of rats. Also, eagles will cause the and rabbit population to increase, decreasing the plant population and therefore decreasing the rat population because of the lack of food.
tldr; rats will decrease if eagles died of disease.
Answer:
The rabbit population willl increase because the eagles are not present to feaast on them. The population of the snake will also increase since the Eagles are not present and the rat's population will increase as welll because it's only 1 animal who is eating them.

Describe how the egg gets from the ovary to the site of fertilisation.
Answer:
The ovaries produce the egg cells, called the ova or oocytes. The oocytes are then transported to the fallopian tube where fertilization by a sperm may occur. The fertilized egg then moves to the uterus, where the uterine lining has thickened in response to the normal hormones of the reproductive cycle.

Is a reflex part of the central
nervous system, the peripheral
nervous system, or both? Explain.
Answer:Because the peripheral nervous system transmit reflex impulses from sense organs to central nervous system and then back to the sense organs. So both the Central nervous system and the peripheral systems are involved.
To understand a bit better.....
One of our body parts consists of a nervous system it is a complex network of neurons and cells that carry pieces of information to and from the brain and spinal cord to various parts of the body.
So in conclusion...
Yes! The Central nervous system and the peripheral systems are involved!So therefore your question is correct!
