What happens within the cell of a eukaryotic organism when an organelle is no longer functioning properly
Answers
Final answer:
When an organelle within a eukaryotic cell fails to function correctly, the cell may utilize autophagy to degrade and recycle the component, or it might trigger apoptosis if the damage is substantial, showcasing the cell's self-maintenance capabilities.
Explanation:
When an organelle within a eukaryotic cell is not functioning properly, the cell can employ several mechanisms to deal with the malfunction. One such mechanism is the autophagy process, where the cell degrades and recycles the damaged organelle. Alternatively, if the damage is too extensive, the cell may undergo programmed cell death, also known as apoptosis, to prevent harm to the organism as a whole. This showcases the cell's ability to maintain internal stability and health, ensuring its optimum functioning within the greater context of an organ or organism.
Autophagy serves as a quality control mechanism, allowing cells to remove malfunctioning organelles and recycle their components, thereby supporting cellular function and health. Similarly, apoptosis plays a crucial role in development and disease prevention by eliminating cells that cannot be repaired. This intricate balance of creating, maintaining, and, when necessary, decomposing cellular components underlines the sophistication of eukaryotic cells.

which of the following statements best describes what happens during the S phase of the cell cycle?
Answers
The S phase of the cell cycle is when DNA replication occurs, resulting in two identical copies of each chromosome (sister chromatids) and the duplication of the centrosome.
Explanation:The S phase, or synthesis phase, of the cell cycle involves the replication of DNA. This is significant because when a cell divides, it is essential that each new cell possesses an exact copy of the DNA. During the S phase, mechanisms result in DNA replication and the formation of two identical copies of each chromosome, known as sister chromatids, firmly attached at the centromeric region. The centrosome, which plays a vital role in dividing the chromosomes during mitosis or meiosis, is also duplicated during the S phase. In animal cells, centrosomes are associated with a pair of rod-like structures known as centrioles, which organize cell division. It is important to note that centrioles are not present in the centrosomes of several eukaryotic species, including plants and most fungi.

During the S phase of the cell cycle, DNA replication occurs, resulting in identical pairs of DNA molecules known as sister chromatids. The centrosome, which aids in chromosome movement during mitosis, is also duplicated during this phase.
Explanation:The statement that best describes what happens during the S phase of the cell cycle is that it involves the process of DNA replication. In the S phase, DNA replication can proceed through the mechanisms that result in the formation of identical pairs of DNA molecules-sister chromatids-that are firmly attached to the centromeric region. The centrosome is also duplicated during the S phase, giving rise to the mitotic spindle, the apparatus that orchestrates the movement of chromosomes during mitosis.
The S phase is vital to the cell division process as it ensures that each daughter cell receives an identical and complete set of DNA. It should be noted that although DNA replication is the central event in the S phase, many other biochemically active processes occur including cell growth and protein synthesis.

Which survivorship strategy is used by the type II species?
Answers
Answer:
Type II species include mice, birds and other similar organisms that have constant survivor ship rates as well as mortality rates during the whole period of their expected life/
If we look at survival ship curve of type II species as depicted in attached figure, we can see that it shows a constant slope and contains a straight line. The slope is in such a way that with the passage of time it decreases till reach zero.
The survival ship strategy used by type II species is this that they lie somewhere between semelparous ( comprised by single reproductive episode before death) and iteroparous (comprised by multiple reproductive cycles throughout the lifetime).
They have a probability of dying at constant level therefore they adopt a strategy in between of having more than one and less than multiple reproductive cycle throughout their life. In this way, they maximize their survival span.

Which type of substances serves as a catalyst for reactions that break large food molecules into smaller useful molecules
Answers
Enzymes serve as catalyst that breakdown large substance into smaller molecules. Enzymes are proteins that function as biological catalysts to speed up chemical reactions in an organism.
Answer:
Enzymes.
Explanation:
Enzymes are the substances which play the role of catalysts in bio-chemical reactions. These enzymes are proteins and play a very important role in glycolysis stage of cellular respiration in which large food molecule like glucose is broken down into smaller useful substance like pyruvate. Some enzymes which participate in glycolysis are phosphofructokinase, enolase, pyruvate kinase etc. This pyruvate is further converted into even smaller molecules like Acetyl-CoA which enters the next stage of cellular respiration known as TCA cycle.
TCA cycle produces many intermediates (molecules) which are useful for other bio-synthetic pathways in the body. For example: Alpha-ketoglutarate which is an intermediate of TCA cycle is used in the synthesis of many amino acids like glutamine, proline, and arginine.
What type of organic molecule will be created if alanine bonded with many other amino acids such as serine and glycine
Answers
Ans.
The organic molecules that formed by the amino acids are known as proteins. Each amino acid binds with other amino acid with the help of peptide bond between amino group of one amino acid and carboxylic group of another amino acid.
Thus, 'when alanine binds with other amino acids, such as with glycine or serine, a protein molecule will formed.'
Alanine bonded with amino acids like serine and glycine forms a polypeptide. This molecule is linked by peptide bonds through a dehydration synthesis reaction, and its sequence determines its structure and function.
Explanation:When alanine is bonded with many other amino acids, such as serine and glycine, the organic molecule created is a polypeptide. A polypeptide is a long chain of amino acid residues linked together by peptide bonds. Each amino acid is attached to the next by a dehydration synthesis reaction, releasing a molecule of water and forming the peptide bond. The sequence in which these amino acids are linked determines the primary structure of the polypeptide. For example, the sequence Gly-Trp-Ala is distinct from Ala-Trp-Gly because the location of the free amine and carboxyl groups would be different. The polypeptide can fold into complex shapes to form proteins which have variable functions, depending on their amino acid sequence and resultant three-dimensional structure.

Green and brown algae share many common features. Both have pigments for trapping sunlight and use photosynthesis for energy. Both store their food as sugars. Both have cell walls and plant-like bodies. However, their DNA suggests that they are not even remotely related to one another. Green algae and brown algae show __________________ evolution, since they look similar, but are not close relatives.
Answers
Answer:- Convergent
Explanation :-
Convergent evolution is the process in which the organisms that are not closely related evolve independently in such a way that they acquire similar traits due to similar environment in which they live or the ecological niche that they occupy. Such structures that result from convergent evolution are called as analogous structures, which perform similar function but have different origins. Convergent evolution can be distinguished from parallel evolution in the fact that in parallel evolution similar traits develop in different species which shared a common ancestor and hence, are closely related.Thus, since the brown and green algae look similar but are not close relatives they show convergent evolution.

Answers
Answer : incomplete dominance
Explanation:
For a given trait, there are basically two types of alleles that are present. One allele is the dominant one and the other is recessive. Generally , the phenotype of an individual corresponds to the one coded by the dominant allele when both the alleles are present for a given trait, that is if a heterozygous condition is there. However, in some cases the dominant allele is not completely dominant over the recessive allele.When the dominant allele is not completely dominant then under heterozygous condition the phenotype expressed is a blend of the phenotypes expressed by both the alleles. For e.g if a red flower is crossed with white flower and we get a pink flower we can say that the allele shows partial dominance over the other. Similarly in the given question, the dominant allele is partially dominant over the recessive allele thus, a blended phenotype appears in the progeny. Such type of inheritance is known as incomplete dominance, partial dominance or semi dominance.______ is a nonliving part of an ecosystem that gives plants the energy they need to make food.
