walking are very similar to the bones of
whales' flippers that are involved in
swimming. These are examples of -
F: analogous structures
G: homologous structures
H: vestigial structures
J: endosymbiosis
Answers: G
Answers
Answer:
Your answer is most likely G), so you are correct.
These are the example of Homologous structure. So, the correct option is (G).
What are different types of structures?Homologous structures are similar in structure and location, but perform different functions, resulting in divergent evolution. For example, An arm of a human, the leg of a dog or a flipper of a whale are all homologous structures.
Analogous structures are similar in function but have different origins and structures resulting in convergent evolution. For example, from wings in birds, bats and insects to fins in penguins and fishes are all analogous structures.
Structures with similar anatomy, morphology, embryology, and genetics, but dissimilar functions are known as homologous structures, while structures that are superficially similar but perform the same physiological function are referred to as analogous structures.
Thus. these are the example of Homologous structure. So, the correct option is (G).

Which of the following occurs in lactic acid fermentation?
a. Electrons pass through the electron transport chain.
b. Oxygen is consumed.
c. Lactic acid is converted into pyruvic acid.
d. NAD+ is regenerated for use in glycolysis.
Answers
Answer:
D
Explanation:
Thats all i know hope it helps
Lactic acid is created when pyruvate is reduced to make it, while NAD+ is created when NADH is oxidized. Reducing pyruvate to lactate requires a proton from NADH and electrons from the molecule. Thus, option D is correct.
What is the role of Lactic acid fermentation?Anaerobic respiration occurs when human muscle cells do not receive enough oxygen. So, the fermentation of lactic acid results in the production of energy molecules. The result of this process is lactic acid.
Oxidize electron transporters to allow for glycolysis re-use. Without the aid of oxygen, fermentation enables cells to generate chemical energy from the breakdown of sugar, such as glucose.
Therefore, in lactic acid fermentation, NAD+ is regenerated for use in glycolysis.

A. Photosynthesis releases energy and cellular respiration stores energy.
B. Photosynthesis releases carbon dioxide and cellular respiration releases oxygen.
C. Photosynthesis removes oxygen from the atmosphere and cellular respiration replaces it.
D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
???
Answers
Photosynthesis and respiration depend on each other and complement themselves. Option D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.
Why are Photosynthesis and respiration complementary processes?Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria.The photosynthetic process needs solar radiation to produce organic compounds, while the respiration process needs the organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.In the process of photosynthesis, it occurs a release of oxygen, which is then used during the respiration process. Both processes produce energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products are carbohydrates and oxygen.
The correct option is D. Photosynthesis removes carbon dioxide from the atmosphere and cellular respiration replaces it.

Use the model here to describe the transfer of matter and flow of energy from one trophic level to another within an ecosystem.
Answers
Answer:
Thanks to light energy or chemical energy, the producers, which are on the base of the pyramid, produce their food. Then, the primary consumers eat the producers. The secondary consumers eat the primary consumers. Lastly, the tertiary consumers eat the secondary consumers. The producers process the residues from all the levels obtaining their food and starting the cycle again. Each level in the pyramid has the matter that the animals in the next level will consume. The animals digest the food and break it down into small components that the body uses as energy and for its structure.
The flow of energy from one level to the other is not efficient. Part of it is lost as heat or due to not good digestion. As a result, the energy transferring as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.
Explanation:
There is a loss of matter from one level to another since some are lost as fecal matter because it could not be processed. The same process happens with the energy from one level to the other. The energy decreases since a part is lost as heat, and the animal uses a part of it to stay alive. As a consequence of this decrease in energy, the higher levels receive less energy than the ones in the lower part of the pyramid.
The flow of energy from one trophic level to another within an ecosystem. Part of it is lost as heat or due to not good digestion.
What is the relationship between Biodiversity and ecosystem?Biodiversity has three levels - ecosystem, species and genetic diversity. Therefore, Biodiversity can be defined as the variability among living organisms involving terrestrial, marine, and other aquatic ecosystems, genes and alleles in a species and their ecological complexes such as diversity within species, and between species of the ecosystems.
As a result, the energy transferred as we ascend in the pyramid is lower, making it impossible to continue the pyramid since there is not enough energy to nourish another level.

Can someone tell me what's the syllabus taught in American high schools, like in 10th grade? I'm not an American student and I'm just curious. (didn't mean to sound creepy). thank you so much.
Answers
Before higher education, American students attend elementary and high school for a combined total of 12 years. These years are known as the period from first grade to twelfth grade.
At the approximate age of six, American children begin elementary school, which is exclusively called “elementary school” (elementary school). They attend this school for five or six years and then go on to high school.
High schools are made up of two programs: the first is called "middle school" or "high school" (middle school) and the second is called "high school" (high school). A diploma or certificate is awarded upon graduation from high school. Upon graduation from high school (twelfth grade), American students can go on to college or university. Studies at a college or university are known as "higher education."
What is the process of mRNA creating a protein?

Answers
The explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.
During gene transcription, a fragment of DNA called gene is used as template to create a complementary messenger RNA (mRNA).Subsequently, this mRNA is then used as template to generate a protein by a process called translation.This mRNA is a single-stranded nucleic acid instead of a double-stranded nucleic acid (like DNA).In conclusion, the explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

Altos niveles de ATP en la célula son necesarios para realizar ciertas funciones vitales tales como reproducirse.A qué piensas que se deba esto
Answers
Answer:
el ATP es la moneda energética que la célula utiliza para llevar a cabo diversas funciones metabólicas (incluida la reproducción)
Explanation:
La adenosín trifosfato (ATP) es la principal fuente de energía para la mayor parte de los procesos celulares. La hidrólisis del ATP libera energía química almacenada en los enlaces de fosfato de la molécula, la cual es utilizada por la célula para llevar a cabo diversas funciones, incluida la reproducción. La hidrólisis de ATP genera en primera instancia adenosín difosfato (ADP) y un grupo fosfato libre (ortofosfato), esta es una reacción exergónica que libera una enorme cantidad de energía la cual es utilizada por la célula para llevar a cabo diversas funciones metabólicas incluyendo la síntesis de macromoléculas tales como, por ejemplo, proteínas del huso mitótico requeridas durante el proceso de división celular. El ADP también puede hidrolizarse para liberar energía, con la consecuente producción de adenosín monofosfato (AMP) y un segundo fosfato libre.
