Answer:
Your answer is A,
Explanation: D can be argued for as well but those are the secondary functions of scales. Their main function is to protect the fish.
Many fish contain an outer covering of scales. Scales protect fish, much like a suit of armor. All fish have a dirty covering of mucus. This substance permits the fish to swim through the water with very little yawn and also makes it hard for other organism to adhere to the fish.
What are the functions of the parts of a fish?The dorsal and ventral fins mainly help fish to not move over onto their flanks.
The caudal fin is the main fin for propulsion to move the fish forward. The coupled fins help with steering, stopping and hovering.
Thus option "A" is correct, Protects the fish from their environment.

What possibly explains these similarities?
A. This is purely chance and isn't significant.
B. The extinct dinosaur and modern bird share a common ancestor.

D. Dinosaurs choose to fly, and evolved into birds to escape predation and capture food.
Answer:
B sounds like a sensible choice
Explanation:
The extinct dinosaur and modern bird share a common ancestor. So the correct option is B.
What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375

Which type of fuel produces greenhouse gases?
A. Hydroelectric
B. Wind
C. Biomass
D. Nuclear
The type of fuel produces greenhouse gases is the Biomass fuels.
Who are fossil fuels?Fossil fuels include oil and its derivatives, coal and natural gas, all formed by the decomposition of living organisms.
The main cause of the greenhouse effect is industrialization. Due to this process, the burning of fossil fuels has intensified in recent centuries. The main products of the combustion reaction of these reagents are the gases mentioned above as the main ones for the greenhouse effect.
in this case, biomass fuels are plants, animals and their derivatives are biomass. Use as fuel can be made from its raw form, such as wood, agricultural products and residues, forest residues, livestock residues, animal excrement and garbage. In other words, are fossil fuels and podruces greenhouse gases.

Explanation:
Where do majority of tornadoes occur in the United States?
Answer:
central united states
Explanation:
mainly in this area because of cold air coming in from canada and warmer air coming from the gulf of mexico meeting and causing tornados.
Answer:
A majority of tornadoes that occur in the United States, occur in the Midwest and Southeast region of the United States.
Explanation:
Tornadoes can impact just about every U.S. state, but the majority of these storms are concentrated in states throughout the Midwest and Southeast. In fact, of the average 1,137 tornadoes that occur in the United States each year, 64% of them form in states located in “Tornado Alley” and “Dixie Alley”, two regions with a disproportionately high frequency of tornadoes due to atmospheric conditions that persist for long stretches of the year.
With an average of 140 tornadoes annually, Texas is the most tornado-prone state in the U.S., followed by Kansas with 80 and Florida with 59, according to National Oceanic and Atmospheric Administration data.
Top five states with the most tornadoes
Texas - 140

Preparing Informative Presentations
There are a variety of reasons a person presents a speech. Perhaps the most common reason is to present timely or useful information to an audience.
Such speeches are called expository speeches, and they rely on the effective transfer of information to listeners. An expository speech could be a definition speech, which explains an object, person, or event. It could also be a demonstration speech, which explains to the audience how to complete a process or task. A successful informative presentation depends on a few key steps that will help you prepare, inform, engage, and educate.
Based on the tips in the article, come up with a topic of your own that would make an interesting demonstration speech?
