Bat wings, a human hand, and a whale flipper are all ________________structures. Explain WHY?
Butterfly wings and bat wings are examples of _______________ structures.
The mouths of horseflies and mosquitoes are examples of _______________ structures.
A _______________ structure is one that does not currently have a function in the organism. Give an example.
Comparing structures of embryos is an example of __________________.
If embryos share a common structure, what does that say about their evolutionary relationship?
How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.
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 is metabolism?
Metabolism refers to the chemical processes that occur within a living organism in order to maintain life. These processes include the conversion of food into energy and the use of that energy to power the organism's growth, reproduction, and other functions.
Metabolism can be further divided into two main categories: catabolism and anabolism.
Catabolism is the process by which the body breaks down molecules to release energy. It includes the breakdown of complex molecules such as carbohydrates, fats, and proteins into simpler molecules that can be used by the body's cells for energy. This process produces waste products such as carbon dioxide and water which are eliminated from the body.
Anabolism is the process by which the body uses energy to build molecules. It includes the synthesis of complex molecules such as proteins, nucleic acids, and polysaccharides from simpler molecules. Anabolic reactions consume energy, rather than release it, and they require precursors and enzymes.

Answer:
A lion hides in the tall dunes and yellowish collored grass which makes in invisible to other animals nad helps it get prey and not get attacked by hyenas.
Explanation:
Answer:
An animal's color could help it survive by blending into its surroundings so it is less visible to predators and prey.
Example: A polar bear's fur is white, and all the snow in Antartica is also white. Therfeore, it is hard for predators to find the polar bear and for prey to escape because they don't see the polar bear.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.
Answer:
Both creates new cells
Explanation:
Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.
What is meiosis?Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.
In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.
Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.

Explanation:
Why do organisms that fertilise internally tend to produce less eggs?
Answer:
Explanation: Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.

v-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins but are otherwise catalytically inactive. What do you think is the effect of v-FLIP expression in the host cell?A. It promotes apoptosis mainly via the extrinsic pathway.B. It inhibits the extrinsic pathway of apoptosis.C. It activates only the mitochondrial pathway of apoptosis.D. It inhibits the intrinsic pathway of apoptosis.E. It enhances the caspase cascades in both the intrinsic and extrinsic pathways.
Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
