Answers:
1.blank: Homologous
why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.
2.blank: Analogous
why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.
3.blank: Homologous
why?: (see question 1 ^)
4.blank: Vestigial
example: An example of a vestigial structure is a human's tail bone.
why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.
5.blank: Embryology
why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.
6.answer: They share a common ancestor
why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.
7.answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.
why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.

what happens when there is a decrease in carbon dioxide during gas exchange in the body?
Answer:
Increased carbon dioxide means increased blood acidity, while decreased carbon dioxide means increased blood acidity.
The bicarbonate reaction is reversible, which allows bicarbonate to turn back into dissolved carbon dioxide to diffuse from the alveolus.
Phosphorus in soil is transformed into insoluble compounds unless what happens?
Answer:
It is not absorb by the plants, it turns into insoluble form.
Explanation:
Phosphorus in soil is transformed into insoluble compounds unless not used by the plants. The insoluble phosphorus is transform into soluble form in the soil by phosphorus solubilizing bacteria. The phosphorus solubilizing bacteria helps in conversion of insoluble phosphorus into soluble phosphorus which can absorb by the plants. If the phosphorus is not absorb by the plants and present for a long time, it can be converted into insoluble form which is unavailable for the plants which can be converted back with the help of phosphorus solubilizing bacteria.
What is used to regulate gas intake and output with a plant?
Answer-
The plants stomata!
Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals. In optimum conditions, stomata are wide open, allowing gaseous exchange with the atmosphere.
Goats are outside living on the sides of steep mountains. They are eating the
grass and bushes that grow there. It's a clear, sunny day on the mountainside.
What is happening to the carbon dioxide in the air? Is it ONLY being released (as a
product), ONLY absorbed (as a reactant), or being released AND absorbed?
CO2 is being both released by goats in exchange for O2 and absorbed by the plants in exchange for O2, too

What is inside an animal cell?
Answer:
Nucleus, vaculoe, cytoplasm, cell membrane
thats all I can remember
Answer:
Nucleus,cytoplasm, endoplasmic reticullum,ribosome,mitochondria,Gollgi complex,Vacoule and lysosome.
Explanation:
Nucleus - controls cell activities, contains the DNA for the cell.
Cytoplasm - supports and protects all cellular organelles.
Endoplasmic Reticulum - aids in making proteins, carries materials through the cell.
Ribosome - synthesizes proteins.
Mitochondria - breaks down sugar molecules to release energy, site of aerobic cellular respiration.
Golgi Complex - modifies proteins made by the cell, package and export proteins.
Vacuole - store food, water, metabolic, and toxic waste.
Lysosome - break down old cell parts, break down larger food molecules into smaller pieces.

How does air pressure affect
breathing?
Answer:
When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.
Answer:
The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.
O Water is denser than isopropanol, so the water layer will always be below the isopropanol layer if they are both in the same container. What does this tell you about the make-up of the pigments for each specimen?
Answer:
One is polar and the other is non-polar.
Explanation:
The makeup of both water and isopropanol is different from each other due to their polar nature. Water is a polar substance means that it makes poles i.e. positive or negative while on the other hand, isopropanol is non-polar substance so due to this reason water and isopropanol make different layers. If both are polar or nonpolar substances so they will able to mix with each other.
how is specific gravity extracted from the earth?
Answer:
The formula for specific gravity, given that the reference substance is water, is the density of the object divided by the density of the water.
Radiation is a method of thermal energy transfer that moves-
Helppplp plss I’ll choose as brainliest
Answer:
-heat
Explanation:
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.
Good luck!!
Answer:
Explanation:
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .

In what direction do substances diffuse across the cell
membrane?
Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.
Explanation:
A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?
Answer:
The correct answer is - blue and red both.
Explanation:
Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.
Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.

What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective breeding?
Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest." Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators. Natural selection is when the "best" trats are passed down due to chance
Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down. Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur
