the photosynthetic euglenids obtained their chloroplasts, which are surrounded by three membranes, through
a. primary endosymbiosis
b. secondary endosymbiosis retaining the chloroplast from a green alga
c. secondary endosymbiosis retaining chloroplasts from a chlorophyte
d. tertiary endosymbiosis
e. none of the above
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.

The standard of reciprocal base matching in which the base that could successfully bond with adenine is thymine.
Correlative base matching is a crucial rule of hereditary qualities and alludes to the particular matching of nucleotides in DNA. As per this standard, the DNA base adenine (A) consistently coordinates with the base thymine (T) through two hydrogen bonds, while the base cytosine (C) consistently coordinates with guanine (G) through three hydrogen bonds.
The holding of these base sets assists with guaranteeing the solidness and exactness of DNA replication, which is basic for the transmission of hereditary data starting with one age and then onto the next. If an alternate base, like uracil, were to coordinate with adenine, the trustworthiness of the DNA strand would be compromised and hereditary data could be lost or modified.

Today, the Dunkers are genetically unique and differ in gene frequencies, at many loci, from all other populations including those in their original homeland. The mechanisms likely explains the genetic uniqueness of this population is founder effect and genetic drift. The correct answer is D.
In order to establish a new population, Dunkers relocated to Pennsylvania and settled there. It's possible that this new population does not share the same gene pool and allele frequencies for every gene as the original population did. The founder effect describes the shift in a population's allele frequencies that results from a small number of individuals moving into a new territory.
Due to their tiny size, the newly arrived Dunkers in Pennsylvania were more susceptible to any random occurrence that might have increased the genetic diversity of their gene pool.

Daughter cells separate
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.

Without a vaccine, how many people in the United States are estimated to die from Covid-19before herd immunity is acquired
(if the virus does not mutate further)?
Answer:
Explanation:
It is difficult to estimate the exact number of people who will die from Covid-19 before herd immunity is acquired without a vaccine, as it depends on multiple factors such as the prevalence of the virus, the behavior and actions of individuals, the effectiveness of public health measures, and the response of the healthcare system.
However, based on the experiences of other countries and the projections made by public health experts, it is estimated that a significant number of people could die from Covid-19 if a vaccine is not made widely available and effective measures are not taken to control its spread.
It is important to note that the acquisition of herd immunity through widespread illness and death is not a desirable or ethical approach to controlling the pandemic, and that widespread vaccination is the most effective way to protect public health and save lives.
