Do catfish have hair?
a. yes
b. no
Answer:
no they do not have hair, even tough it may look like they have hair its only pieces of skin.
Explanation:
Catfish do not have hair. They have barbels, which are long, thin feelers that are used to sense their surroundings. Hence option B is correct.
The barbels are covered in taste buds, which allow the catfish to taste the water and find food. Hair is made of keratin, which is a protein. Catfish do not have keratin in their skin, so they cannot grow hair.
However, some catfish species have barbels that are covered in small, hair-like projections. These projections are not actually hair, but they are similar in appearance.
Therefore, option B) No is correct.

(4) The coral can be hurt by too much carbon dioxide being dissolved in the water from the air above.
(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.
Answer:
(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.
Explanation:
The atmosphere is a part of coral reef because a large population of organisms lives in these coral reefs. It provides habitat to the biosphere of the ocean as well as oxygen to the marine organisms. It can greatly affected with the increase concentration of carbondioxide due to acidification of water that kills the algae that is lives on the surface of these coral reef. So if these algae die due to lowering of pH, a large portion of marine organisms also removed from the environment due to unavailability of suitable environmental conditions.
POST-lab Question:
What would be the effect on the butterfly population if the coloration in the environment suddenly changed? (Example: green
butterflies are living on a green plant that suddenly turns brown and loses all its leaves).
Answer:
The butterfly population would decrease or die out.
Explanation:
If the population of the green butterfly had depended on these "green plants" or leaves, they would die out without them since they use these green plants to camoflauge and blend in with them. Its something they can use to hide away from predators, and be safe from them.

Explain the Carbon cycle in 3 paragraphs or more.
Answer:
Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1) Carbon present in the atmosphere is absorbed by plants for photosynthesis.
2) These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3) These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4) Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5)These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
Carbon in the atmosphere is present in the form of carbon dioxide. Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels.
There a four shared features of Chordates. Match the feature with the appropriate characteristic or function.

Answer:
1. Notochord.
2. Dorsal hollow nerve cord.
3. Pharyngeal slits.
4. Pharyngeal slits.
5. Notochord.
6. Dorsal hollow nerve cord.
Explanation:
A living system can be defined as the internal systems found within living organisms and how different materials circulate within these organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, circulatory system, and digestive system.
A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.
The four (4) shared anatomical features or characteristics of chordates includes the following;
1. Notochord: found between the digestive tract and nerve cord.
2. Dorsal hollow nerve cord: in some embryos this develops into the central nervous system.
3. Pharyngeal slits: in invertebrate chordates can be involved in filtering food from water ingest through the mouth.
4. Pharyngeal slits: in jawed fish this provides support for the jaw.
5. Notochord: provides skeletal support.
6. Dorsal hollow nerve cord: is derived from the ectoderm.

What is the dose that should be given to this
infant?
Ih natient is nrescribed medication B The
Answer:
100 mg/kg/day.
Explanation:
The recommended dose of medication A is 25 mg/kg and given to the infant after every 6 hours so 100 mg/kg of medication A is given to the infant per day. The medication A is given in small doses not as a whole at one time because it cause problems in the infants instead of treatment. There is no need for medication B if the medication A works effectively on the infant so the per day dose of medication A is 100 mg/kg/

Explain the flaw in Bill's rationale in the following scenario:
Bill, a horse breeder, believes that studying heritability is a waste of time. He thinks that kind of technical study should be left to scientists, not farmers.
He could use this knowledge to help breed his horses to the best that they can be.
What is heritability ?The degree to which genetic variations among persons may adequately explain the variations in their attributes is known as heritability. Characteristics like height, eye color, and IQ are examples of traits, as are illnesses like schizophrenia and autism spectrum disorder.
Heritability, which is denoted by the statistic h2 in science, describes the proportion of a trait's variation that can be attributable to genetic variation.
An estimation of a trait's heritability is particular to one population in a particular setting, and it might alter over time as conditions change.
Estimates of heritability range from 0 to 1. A heritability close to zero means that environmental factors, with very little influence from genetics, account for almost all of the variation in a trait among individuals.
Therefore, He could use this knowledge to help breed his horses to the best that they can be.

1. Which systems (2) are primarily responsible for movement of the body
Answer:
The correct answer is -muscular system and skeletal system.
Explanation:
The skeletal system and the muscular system work together to move the body or body parts. Different types of tissues form the muscular system that and their action on bones controls the movement of the body in vertebrates.
Tendons are tough muscles that attach with the bones and joints allow the movement by contraction of muscle that helps in moving bones from joint. Muscle normally acts by contracting and relaxing in pairs.
