Analogy and homology are important concepts used in comparing species. Traits are homologous if they are derived, evolutionarily and developmentally, from the same source structure. Traits are analogous if they have similar functions but are derived, evolutionarily and developmentally, from different source structures. A classic example of analogous structures is insect wings and bat wings. Which of the following pairs of structures are analogous and which are homologous?
a. Dorsal fins of porpoise and a salmon
b. Flippers of porpoise and pectoral fins (front fins) of salmon
c. Joined leg of ladybird beetle and a robin
d. Rhesus monkey's tail and human's coccyx
e. Bright red bracts of poinsettia and green leaves of rose
f. Red bracts on a poinsettia and red petals on rose
Answer:
a. analogous
b. homologous
c. analogous
d. homologous
e. homologous
f. homologous
Explanation:
a. Analogous. Porpoises are mammals while salmon are fish. In this case, fins are analogous structures that evolved separately in both groups.
b. Homologous. Pectoral fins evolved from the forearms of tetrapods, and early tetrapods evolved from fish.
c. Analogous. These structures evolved independently through convergent evolution in both groups.
d. Homologous. They are homologous structures that were inherited from a common ancestor (primates).
e. Homologous. Bright red bracts (modified leaves) of poinsettia and green leaves of rose share a common ancestor (i.e., angiosperms).
f. Homologous. They are homologous structures that were inherited from a common ancestor (i.e., angiosperms).

If a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.
At carrying capacity, the number of organisms being born equals the number of organisms
competing
dying
surviving
immigrating
Answer:
dying
Explanation:
carrying capacity is where there is only a certain amount animals can enter so the animals being born is the same as the animals dying bc they have no resources

What is something you learned about movement across the membrane
Answer:
Membrane transport is essential for cellular life. As cells proceed through their life cycle, a vast amount of exchange is necessary to maintain function.
Explanation:
I put a picture does anyone know the answer to that
Answer:
C- All members of the population are genetically similar and are less likely to survive environmental change.
Explanation:
In asexual reproduction, there is no diversity since the offspring gets all their genes from their parent. That being said, they won't be able to inherit traits that would help them survive in a changing environment since there is no diversity of traits that would help them in other environments.
Answer:
I think it is C
Explanation:
Reverse faults are the result of tension.

Genes carry the codes that tell the body how to form itself.
True or False
can someone give me good evidence please i will give you brainliest
Answer:
you can get evidence by observing how people have different traits from their parents, like one sibling can look different than they other sibling, they can get traits from older generations, like you can have a family that has black hair or dark brown and one of their kids got light brown hair because that was passed down or skipped through a generation.

2. A man has type A blood and his wife has type B blood. A physician types the blood of their four children
and finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens .
hope it will help . please mark me as brainlist!!PLEASE HELP!!
