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.
Answer:
The correct answer is - Tigers and goldfish are both vertebrates. Vertebrates are animals that have spines and internal bone structures.
Explanation:
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.
Explanation:
What is the exchange of genes between
homologous chromosomes called?
A Crossing over
B. Independent assortment
C. Criss-Crossing
D. Meiosis
A. Crossing over
During synapsis in meiosis (when the homologous chromosomes pair together during prophase I), is when crossing over occurs, and the chromatids of the homologous pairs "cross over" and swap genetic material.

One day you were suddenly awakened by a ghostly shriek as if it were coming from
beneath your bed. Then a shadow seemed to advance towards you. You felt choked and
lost your consciousness. When you regained to your senses you were on your bed,
puzzled but safe. Describe your experience in the form of a short story in about 200–250
words.
(Use only the past tenses, title the story and have a moral at the end)
Answer:
THE NIGHTMARE
I woke up with a start, sweating profusely, my heart pounding erratically against my chest. My hands were shaking uncontrollably and I held my pillow close to my chest to clam my nerves. I had heard it. There was no doubt in it. A loud, high-pitched shriek, which sounded nothing like a human cry. It was surreal, making a shiver to creep up my spine. I twisted my hands together in nervousness, and murmured a prayer to god. The ghostly sound had resonated from beneath my bed. I had read way too many horror stories to not be scared by now. My throat felt dry and parched and I longed for a sip of water. But I had to go downstairs to fetch the jug. That meant I had to get down from my bed. And there was no way I would do that. Not now, when I was literally scared to death. I swallowed hard. My breathing had slowed down a bit but my heartbeat was still erratic. I perked up my ears and waited to see if the shrieks continued. I badly wanted to cover myself with my blanket but I was too scared to move an inch. I waited for about a minute and could hear no sound. This eased me a bit. Just when I mustered the courage to lie back down and go back to sleep, I felt a shadow whisk past me, sending the curtains flying. I brought my hands to my mouth to stop myself from crying out in terror. It was the silhouette of a girl, a tall, slender figure that I was sure by now was somewhere around me. I felt my eyes brimming with tears but I held my cries back. It was when the shadow reappeared, this time closer to me, near my nightstand. And before I could register what was happening or cry out loud for help, the figure advanced towards me, and all of a sudden, held me in a death grip. I felt myself being choked so tightly that no sound was escaping my mouth, black dots swimming in my vision. Soon enough, I plunged into darkness. After what felt like hours, I opened my eyes to be greeted with the golden rays of the sun streaming in through the window near my bed. I had a slightly blurry memory of yesterday night. I felt around my surroundings, and was met by relief when I could feel the blankets and my pillow beside me. Overjoyed by the fact that I was safe, and that it all had been just a silly nightmare, I thanked God and got out of bed to start my day.

HELP!!! why is land considered a resource??
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!
Hope this helps!

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.

function?
A. Circulatory
B. Nervous
C. Endocrine
D. Integumentary
Answer:
Circulatory System

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.

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.

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.
