give a description of the endosymbiont theory of plastid origin. how many times might chloroplasts have arisen?

Answers

Answer 1

Chloroplasts have arisen three times according to the endosymbiont theory.

According to the endosymbiotic theory, some of the organelles in eukaryotic cells of the present day were once prokaryotic microorganisms. The host cell and the endosymbiont each have a set of cell membranes that enclose the chloroplasts that resulted from primary endosymbiosis. When a eukaryotic cell absorbs a cell that has already experienced primary endosymbiosis, secondary endosymbiosis takes place. They surround the chloroplasts with more than two sets of membranes, as in chloroplasts of brown algae. When a eukaryotic cell assimilated another eukaryotic that was the product of an earlier secondary endosymbiosis, this process is known as tertiary endosymbiosis.

Therefore, chloroplast, as well as mitochondria, have occured thrice and are very different from the current prokaryotes like cyanobacteria.

The limit of change resulted from the regeneration process is very clear in option B: Planaria

Has Planaria the ability to regenerate?

Most fishes and salamanders have limited limb regeneration, while larval frogs and toads have tail regeneration (but not adults). After being amputated, a salamander's or a triton's entire limb will continue to develop.

Therefore, Planarians are flatworms (phylum Platyhelminthes) that live in freshwater bodies, and their capacity for regeneration has long been known (Pallas, 1766; Dalyell, 1814). In a procedure that takes days to weeks, planarians can regenerate new heads, tails, sides, or even complete organisms from tiny body parts.

a new hormone is discovered that appears to play a role in bone development. the hormone is hydrophilic and composed of several amino acids. how should this hormone be classified?

Answers

Hormonal transport, because some hormones are water soluble, they can move around freely in the circulation (hydrophilic). Since the steroid hormones are fat soluble and hydrophobic, transport proteins must bind to and move them (like albumin and globulins which are blood proteins produced by the liver).

The membrane is permeable to hydrophobic hormones, which allow them to diffuse through and engage with an intracellular receptor. Contrarily, hydrophilic hormones need to engage cell membrane receptors in order to function. These are frequently linked to a G protein, which is activated as soon as the hormone binds the receptor.

Our brain's pituitary gland produces growth hormone, which controls how tall we get, how long our bones get, and how big our muscles get.

175,000 kcal/m2/yr , and the plant respiration is estimated to be 115,000kcal/m2/yr . what is the total amount of energy transferred during photosynthesis for this ecosystem?

Answers

The total energy exchanged during photosynthesis for this environment is 290,000 cal/m2/yr.

The term "net primary productivity" refers to the amount of energy retained by an environment's biomass when energy is released for metabolism and maintenance. Net primary productivity, as opposed to gross primary productivity, refers to the total energy input into the ecosystem before taking into account energy loss.

Net primary productivity (NPP) is calculated mathematically as Gross Primary Productivity (GPP) - Respiration.

NPP = 175,000 cal/m2/yr for the pine forest, and respiration = 115,000 cal/m2/yr, hence GPP = 175,000 + 115,000 = 290,000 cal/m2/yr.

Therefore, 290,000 cal/m2/yr of energy is transported throughout photosynthesis for the environment as a whole.

Answers

crossovers between these genes result in chromosomal exchange.

Linked genes move along at the same anaphase.

Genes that are near to one another on the same chromosome are linked and move through meiosis together. As a result, related genes do not assort separately.

The genes are positioned near together if the recombination frequency is low; however, if it is high, the genes are spread out.

Every trait is inherited independently of every other trait, according to Gregor Mendel's Law of Independent Assortment.

Antibodies are protein molecules that the body produces in reaction to the introduction of foreign substances (also known as antigens or immunogens).

When an organism's immune system comes into contact with a foreign molecule for the first time (usually a protein), specialized cells like dendritic cells and macrophages seize the molecule and start to break it down so that they can transmit these antigens to B cell lymphocytes. A process known as somatic hypermutation enables the B cell to start coding for a new antibody after antigen presentation to the B cell lymphocytes has taken place.

What is a karyotype?

A karyotype is a term used to refer to the complete set of an individual's chromosomes. It refers to the total number of chromosomes found in each individual cell. The karyotype is the individual's chromosomic dotation.

Each species has its own karyotype because the number of chromosomes per species might vary. For instance,

The karyotype of human beings is composed of 23 pairs of chromosomes or 46 chromosomes.

The karyotype of Drosophila melanogaster is composed of 4 pairs of chromosomes.

Whenever there is affection, karyotypes might vary among individuals of the same species. For example, people affected by Down syndrome have 47 chromosomes in pair 21 because of a chromosomic segregation failure during meiosis.

The karyotype concept can also be used to refer to clinical diagnosis.

When looking at the exposed karyotype, we can say that,

A) The individual is a male because there is an X and a Y chromosome.

B) This is a human being's karyotype but does not belong to a sperm cell.

Let us remember that sperm cells are gametes, and gametes are haploid. The number of chromosomes found in gametes is 23.

This karyotype represents a diploid cell with 44 autosomes and 2 sexual chromosomes aligned and paired with their homologous chromosome.

C) There is a trisomy in what should be pair 16. There are three chromosomes instead of two. This fact is evidence of a failure in homologous chromosome segregation during the anaphase of meiosis (non-disjunction).
