(All answers online seemed incorrect)

Answers

E) one that creates a paradigm where diversity is reduced and vegetation growth slows is a type of land grazing.

What is the overgrazing of land?

Overgrazing of land is when livestock are allowed to graze on the same land for too long, often leading to the degradation of the land. This is especially common in areas where there is not enough land to support the number of animals present.

Overgrazing can lead to the destruction of plant life, soil erosion, and the depletion of essential minerals and nutrients in the soil. When the land is no longer able to produce crops, it is unable to support the local community and its wildlife.

Overgrazing can also lead to an increase in dust and air pollution due to the lack of vegetation. Overgrazing is a serious environmental issue that can have long-term impacts on the health and productivity of the land.

The extraction of energy from glycogen occurs in several steps. The step following glycogenolysis would beGlycolysis

Answers

The extraction of energy from glycogen occurs in several steps. The step following glycogenolysis would be Glycolysis.

Glycogenolysis is the breakdown of glycogen into glucose molecules, which can be used as a source of energy. Once the glycogen has been broken down, the glucose molecules enter the glycolysis pathway. In glycolysis, glucose is converted into pyruvate through a series of enzyme-catalyzed reactions, generating energy in the form of ATP. The process of glycolysis does not require oxygen, making it an important source of energy for cells when oxygen is limited.

Through these pathways, the energy stored in glycogen can be efficiently extracted and used by cells to support their various functions.

Answers

If the genomes of two species determine some very large differences. this would suggest that the two species are not closely related.

If two species have large differences in their genomes, it suggests that they have been evolving independently for a significant amount of time and have therefore diverged from a common ancestor. The instructions in our genome are made up of DNA. Within DNA is a unique chemical code that represents our growth, development, and health. This means that they are not closely related, and are likely to belong to different genera, families, or even higher taxonomic groups.

according to the hypothesis of trophic cascades in food chains, heavy predation in a system with four trophic levels (e.g., tarsobaenus beetles in costa rica discussed in slides) should lead to: group of answer choices
a. increased primary b. production decreased c. primary production d. decreased rates of herbivory both

Answers

According to the hypothesis of trophic cascades in food chains, heavy predation in a system with four trophic levels (e.g., Tarsobaenus beetles in Costa Rica) should lead to decreased rates of herbivory, which can result in increased primary production. Correct answer: letter C.

This is because the predation reduces the amount of herbivores in the system, allowing more of the plant material to be processed into usable energy, which can then be used by other organisms in the ecosystem.

This is beneficial to other organisms in the food chain, as they can now access more of the energy that was previously held back by the large number of herbivores. This increased energy can then be used to fuel the growth and development of other organisms, allowing for increased primary production and biodiversity in the ecosystem.

Answers

During the DNA replication of a dividing cell, first the DNA unzips to form replication forks, then DNA is synthesized bidirectionally, then terminator site is replicated which is followed by formation of septum and then the daughter cells separate.

DNA replication is basically the process by which a particular cell replicates the DNA which is present in it. A number of different enzymes play their function in this process. This is necessary for a dividing cell to ensure both the daughter cells are getting equal amount of DNA.

In this process, the DNA first unzips at the origin and two replication forks are formed. The replisomes then happen to synthesize the new DNA strands in a bidirectional manner. This is followed by the replication of the terminator site. The septum is then formed and the cells finally divides to form two daughter cells.

c. secondary endosymbiosis retaining chloroplasts from a chlorophyte
d. tertiary endosymbiosis
e. none of the above

Answers

The correct answer is option (B).  euglenids obtained their chloroplasts from secondary endosymbiosis retaining the chloroplast from a green algae.

All plants and a number of distantly related protist taxa have chloroplasts. There are numerous varieties of chloroplasts, which can contain various kinds of photosynthetic pigments and be encircled by two, three, or four membranes. Despite these variations, the origin of all chloroplasts may be traced to the first endosymbiosis, or the engulfment of an ancestral cyanobacterium by a bigger eukaryotic cell. In an endosymbiotic relationship, one organism lives inside another.

In secondary endosymbiosis, a photosynthetic eukaryote—which later develops into a chloroplast—is ingested by a eukaryotic cell. The nucleus of the enveloped cell has been lost in certain populations throughout time, while it has been preserved in others. Four membranes may surround this new chloroplast in certain species, whereas the plasma membrane of the swallowed cell has been lost in others, such as euglenids.

The same photosynthetic pigments found in terrestrial plants and euglenids are due to their shared evolutionary history. The third membrane of the euglenid chloroplast also fits into this explanation. Chloroplasts were obtained by the euglenids through a secondary endosymbiotic process. A photosynthetic eukaryote was swallowed by an ancestral euglenid during the process of euglenid evolution; the chloroplast was retained, but the remaining components of the old cell were lost. This timeline of events allows the euglenid chloroplast to have 3 membranes and retain from green algae.

A recessive allele will basically show no effect when a dominant allele is present. This allele is basically a weaker form of dominant allele. It only shows effect when it is present in the homozygous condition and can be present on either paternal or the maternal chromosome.

The alleles can be either dominant or recessive. A dominant allele is always expressed when it is present but a recessive allele only gets expressed in the absence of the dominant alleles. This allele is basically weaker than the dominant allele.

The recessive allele can be present on the paternal chromosome or on the maternal chromosome. This allele will not be expressed in a heterozygous condition. It will only show effect when the individual is homozygous for that particular recessive allele.
