Answer:
Homologous
Explanation:
Homologous structures are similar organs or structures that are found in different animals that suggest they come from a common ancestor. This is evidence of evolution.
The structures might not necessarily look identical and might not perform the same function. For example, the flippers of a dolphin, the wings of a bird, the legs of a dog, and the arms of a human are considered homologous structures.
The nitrogen cycle is an example of a(n) (blank) cycle. The options are biogeochemical, decomposer, energy, water, denitrification, nitrogen fixation, nitrogen limitation, or photosynthesis.
Answer: Biogeochemical, Nitrogen Fixation, and Denitrification
Explanation: A biogeochemical cycle is the cycling of a nutrient through the biosphere and the geosphere. Nitrogen fixation happens when Nitrogen Fixating bacteria take in atmospheric nitrogen and release Ammonia as a biproduct. Denitrifying bacteria then take in the ammonia and break it down into nitrite, nitrate, and finally back into atmospheric nitrogen. The cycle then repeats.
The nitrogen cycle is an example of a biogeochemical cycle. The correct option is A.
What is biogeochemical cycle?The transport and transformation of chemicals in ecosystems is referred to as a biochemical cycle. Wetland hydrologic conditions have a strong influence on these.
These processes cause changes in the chemical forms of materials as well as material movement within wetlands.
These cycles transport the elements required for life to survive throughout the ecosystem.
They are essential because they recycle and store elements, as well as regulate vital elements through physical facets.
A biogeochemical cycle describes how an element or compound, such as water, moves between its various living and nonliving forms and locations in the biosphere.
Water, carbon, nitrogen, phosphorus, and sulfur cycles are all important biogeochemical cycles for living organisms.
Thus, the correct option is A.

Amoebas obtain food by wrapping the cell membrane around the food particles, creating a vesicle. The food is then brought into the cell. This process is known as ____________.
a. photosynthesis
b. exocytosis
c. endocytosis
d. osmosis
Answer:
endocytosis
Explanation:
Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested material.
Answer: Your answer is: C. (endocytosis)
Explanation:
The Doppler effect occurs when a source of waves and/or observer move relative to each other, resulting in the observer measuring a different frequency of the waves than the frequency that the source is emitting.
True

False?
Science Plz Help!!!!!
Answer:
So, I would believe that the answer is C) A laser beam looks bent when it passes through glass blocks. So we know that refraction means the fact or phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.

what do many green plants have a part that grows up
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
Explanation:
Which absorbs more carbon dioxide: the atmosphere or the ocean?
Answer:

Explanation:
how can you use the electron configuration to determine the number of valence electrons
Here, we are required to explain how the electronic configuration can be used to determine the number of Valence electrons.
The algebraic sum of electrons in the highest energy level in an electron configuration is the number of Valence electrons of the element.Valence electrons simply refers to electrons present in the outermost shell of an element.
Valence electrons simply refers to electrons present in the outermost shell of an element.The electron configuration is a representation of the arrangement of electrons in the atomic orbitals of an element.
The number of electrons present in the outermost shell as evident from the electron configuration can be used to determine the Valence electron in the elements.Fir instance: the electron configuration of potassium; 1s² 2s² 2p⁶ 3s² 3p⁵
The algebraic sum of electrons in the energy level 3 therefore is the number of Valence electrons.

Why does a Chlamydomonas organism need to locate light
Answer:
the ability to detect the direction of light, to make the right turn and to stay oriented, is a direct consequence of the helical path of the organism, the orientation of its eyespot relative to the helix-axis, and the special shielding properties of eyespot and cell body.
Explanation:
hope this helps :)
Chlamydomonas is an algae. It is a biflagellate organism. It can swim and therefore, exhibit phototaxis. Chlamydomonas needs to locate light in order to move and grow.
What is Chlamydomonas?Chlamydomonas is a biflagellated algae which exhibits both positive and negative phototaxis. Phototaxis is the directional movement of an organism in response to light (stimulus).
The green alga, Chlamydomonas reinhardtii, can swim toward light (positive phototaxis) to increase photosynthesis, but it can also swim away from bright light (negative phototaxis) to avoid damage to molecular complexes required for photosynthesis.
Chlamydomonas grows at a faster rate with higher light intensity due to its photosynthetic nature, provided all other required nutrients for its growth are constant in all treatments. Light acts as an important factor for growth in these organisms.

A bacterium, containing one circular DNA chromosome, undergoes four rounds of replication. How many new strands of DNA would result?
Answer:
The correct answer is 32 strands.
Explanation:
In bacterium, DNA replication is bidirectional which means it takes place in both directions. The origin of replication starts the replication, it is a specific sequence of nucleotides. Each strand of circular DNA acts as a parent strand to replicate its complementary new strand, resulting in two new DNA strands, one parent strand, and one new synthesized strand. So after the first round of replication, there are 4 strands formed.
Similarly, during the second round of replication each of the four strands will be synthesized lead to a total of 8 strands in the same manner. So by the same process in 3rd round will lead to 16 new strands and by the fourth round of replication 32 strands will be synthesized.
Thus, the correct answer is 32 strands.

Roads are onen bum through forests for industrial purposes or as land is developed for residential and commercial needs. How would road construction
through a forest most likely affect the ecosystem?
Non-native species would replace native species
The number of primary consumers would increase
The natural succession of vegetation would change
All producers would be eliminated from the community
Answer:
The natural succession of vegetation would change
Explanation:
Originally, a forest is an area rich in biodiversity of species. It consists of different populations, and communities. According to this question, if a road is built through a forest for industrial purposes, this will negatively affect the biodiversity of such forest.
One notable occurrence that would result from this is the CHANGE IN THE NATURAL SUCCESSION OF THE VEGETATION. This change is the destruction of the ecosystem that occurs due to industrialization (road construction).
