1. Which biotic factors do you see in the photo?
2. Which abiotic factors can you detect in this photo?
3. In what ways does one biotic factor interact with the abiotic factors?
4. Pick one biotic factor and change it dramatically somehow. How will this change affect the aquarium?
5. Pick one abiotic factor and change it dramatically somehow. How will this change affect the aquarium?
Answer:
1. Biotic components of the ecosystem refer to all the living organisms present in the ecosystem. So, fishes and plants would be the biotic components.
2. Abiotic components of the ecosystem refer to the physical or non-living component of the ecosystem. Thus, water and rocks would form the abiotic component of the given ecosystem.
3. The biotic and abiotic components are linked through energy flow and biogeochemical cycles. For example, fishes get oxygen from water and excrete their waste product in the water. Similarly, plants also get carbon dioxide and water for photosynthesis from the abiotic component.
4. Change in the biotic component would disturb the whole ecosystem. For example, if plants are reduced or removed from the ecosystem, enough amount of food and oxygen would not be produced. Similarly, if the number of fishes is increased to a large number, then it might be difficult for the ecosystem to sustain for a long time.
5. The abiotic component is also essential for the ecosystem. Any change in the abiotic component can produce severe effects on the ecosystem. For example, if water is removed or highly polluted then the living organisms would not be able to survive in the ecosystem.

What is the function of the toothlike projections at the dorsal edge of the clam’s valves
The toothlike projections are important structures that contribute to the clam's survival, feeding, and habitat interactions in its aquatic environment.
1. Protection: They help protect the clam from predators by providing a physical barrier. These projections can make it more difficult for predators to access the soft body tissues of the clam.
2. Attachment: They can aid in anchoring the clam to its substrate, such as sand or mud, by providing additional surface area for attachment. This helps the clam remain in place and resist being dislodged by water currents or predators.
3. Burrowing: In species of clams that burrow into sediment, these projections can assist in digging and maintaining burrows. The toothlike projections help the clam grip and manipulate sediment particles as it burrows into the substrate.
4. Filter feeding: Some toothlike projections may also play a role in filter feeding, allowing the clam to capture and filter food particles from the surrounding water.
Which of the following is most likely to happen if a cell is not able to divide?
The cell will create two identical daughter cells.
The cell will absorb oxygen during photosynthesis.
The cell will not be replaced when it is damaged.
The cell will not release carbon dioxide during respiration.
The most likely to happen if a cell is not able to divide is The cell will not be replaced when it is damaged.
Why is it important for the daughter cells to divide a second time in meiosis?Because meiosis makes cells that are fated to become gamete this decrease in chromosome number is required without it, the association of 2 gametes during fertilization.
Thus, option "C" is correct, is most likely to a cell is not able to divide.

What is the generalized term for the specialized structures inside the cell? organelles ribosomes Golgi apparatus eukaryotes
The term for the specialized structures inside a cell is organelles. These include ribosomes, the Golgi apparatus, and the nucleus found in eukaryotes. They each perform specific functions to help the cell survive.
Explanation:The generalized term for the specialized structures inside cell is organelles. Organelles are like the organs in our body; they perform specific functions that help the cell survive. Examples of organelles include the ribosomes which produce proteins, the Golgi apparatus which sorts and packages proteins, and the nucleus which is generally found in eukaryotes and controls cellular activities.
Eukaryotes, which include organisms like plants, animals, and fungi, are characterized by the presence of organelles, distinguishing them from prokaryotic cells (like bacteria), which lack these membrane-bound structures. Organelles enable eukaryotic cells to compartmentalize and efficiently perform various tasks.

How do jellyfish reproduce? Explain, in complete sentences, the process and use the words polyp and medusa.
Answer: The answer is "In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs into the water, forming a planula. The polyps clone themselves and bud, or strobilate, into another stage of jellyfish life, called ephyra. It is this form that grows into the adult medusa jellyfish."

Which of the following correctly describes the difference between transcription and translation?
-Transcription makes RNA from DNA, translation turns RNA into proteins
-translation copies new DNA, while transcription makes RNA
-translation makes mRNA while transcription makes tRNA
-Translation makes RNA from DNA, transcription turns RNA into proteins
Answer:
Transcription makes RNA from DNA, translation turns RNA into proteins.
Explanation:
Transcription is the first stage in gene expression in which an RNA molecule is made by copying a gene's DNA sequence. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides together to make an RNA strand, while translation is also a process in gene expression in which messenger RNA (mRNA) is decoded within a ribosome to build a chain of amino acids which later folds to form an active protein. Translation occurs after the process of transcription.

The region of a chromosome where two sister chromatids are held together is called the centromere.
Each chromosome is made up of two identical copies called sister chromatids.The centromere is a highly condensed, constricted area where the chromatids are most closely connected.After DNA replication, the centromere is the region that ensures the sister chromatids stay conjoined.The connection through the centromere is crucial for proper chromosome segregation during cell division.
okay consider a cross of beetles with exoskeleton allies B and b and leg size alleles N and n. the male parent is heterozygous in both traits. the females parent is homozygous recessive in both traits
Answer
This cross will generate puppies with the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn.
Explanation:
In this case the parent beetle has genotype BbNn and the mother beetle is bbnn. To solve this intersection, we have to remember Mendel's law of independent segregation and perform the traits intersections separately and multiply the percentages later.
1 - Characteristic of the exoskeleton: Bb x bb that gives us 50% Bb, 50% bb.
2 - Leg feature: Nn vs nn which gives us 50% Nn and 50% nn as well.
Finally, that means the cross of beetles have a chance to origin puppies with (0,5 * 0,5) in each different trait, resulting in the genotypes of 25% BbNN, 25% Bbnn, 25% bbNn and 25% bbnn
