Answer:
sickle cell
Explanation:
Answer:
Sickle cell anemia
Explanation:
Hemoglobin serves to carry oxygen and is present in red blood cells. Sickle cell anemia is caused by a point mutation in one of the hemoglobin gene that codes for its beta chain. The mutated allele of the beta globin chain encodes the abnormal hemoglobin molecules which stick to one another resulting in sickle shaped red blood cells.
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.

There are three parts to the cell theory. Which is NOT one of those parts?
Select one:
a. Cells spontaneously arise from carbon and nutrients carried in the bloodstream.
b. The cell is the basic unit of structure and organization in organisms.
c. All cells come from pre-existing cells.
d. All organisms are composed of one or more cells.
Answer:
a. Cells spontaneously arise from carbon and nutrients carried in the bloodstream is not the part of the cell theory.
Explanation:
Cell theory is a biological hypothesis that states that all beings are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells. It was first proposed in the mid-nineteenth century.

scientists discovered a new organism in the Antarctic. the organism grows in colonies and is made up of eukaryotic cells. in which domain does this organism belong?
The new organism discovered in the Antarctic by the scientists is made up of the eukaryotic cells and grows in colonies. The presence of eukaryotic cells means that the genetic material is present inside the membrane bound nucleus, and membrane bound cell organelles are present inside the cell. These are the characteristic of the organism belong to the domain of Eukarya.
Hence, the answer is 'Eukarya'.

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.

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

Genetically-different __________ are the kind of cells made from meiosis.
parents
splices
gametes
Gametes are the genetically different kind of cells which are produced as a result of meiosis. Meiosis is a reductional division in which the chromosomes are reduced to half. Genetic variation in the gametes is due to crossing over between two non-sister chromatids of a homologous chromosomes during meiosis.
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.
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."
