According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate?
a) when a protoeukaryote engaged in a symbiotic relationship with a protocell
b) from infoldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions
c) from the nuclear envelope folding outward and forming mitochondrial membranes
d) by secondary endosymbiosis
e) from engulfed, originally free-living proteobacteria
Answer:
e) from engulfed, originally free-living proteobacteria
Explanation:
The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!
According to the endosymbiotic theory of the origin of eukaryotic cells, mitochondria formed from engulfed, originally free-living proteobacteria. The correct option is e.
What is proteobacteria?Proteobacteria are a major phylum (group) of bacteria. Pathogens such as Escherichia coli, Salmonella, Vibrio cholerae, Helicobacter pylori, and many others are among them.
Others are free-living, and they include many of the bacteria that fix nitrogen.
Proteobacteria, which includes mesophilic and neutrophilic bacteria, is the second largest phylum of hydrogenogenic CO oxidizers. Members of this phylum can be found in a variety of classes.
According to the endosymbiotic theory, mitochondria and chloroplasts were once free-living bacteria that were phagocytized but not digested by another cell.
According to the endosymbiotic theory of eukaryotic cell origin, mitochondria evolved from a rickettsia that was phagocytized but not digested by the larger cell.
Thus, the correct option is e.

Distinguish between the following pairs.
a.active transport and passive transport
b. exocytosis and endocytosis
c diffusion and osmosis
d. hypertonic and hypotonic
Answer:
Explanation:
a. active transport is against the concentration gradient and uses atp. facilitated diffusion is with the concentration gradient and doesn't use atp
b. endocytosis is substances being engulfed in the cell membrane, exocytosis is substances being released from the cell membrane
c. diffusion is the movement of particles through the membrane and osmosis is specifically the movement of water
d. hypertonic means more solute, hypotonic means less solute.
2. What evidence was found to support the different parts of cell theory?
Answer:
The invention of the electron microscope allowed them to see organelles and other structures smaller than cells. There is variation in cells, but all cells have a plasma membrane, cytoplasm, ribosomes, and DNA. These similarities show that all life on Earth has a common ancestor in the distant past

Which statement regarding the relative ages of rocks and events is
accurate? *
A. Intrusive rock is older than the surrounding rock layers.
B. A fold is older than the oldest rock layer it contains.
C. Faults are younger than the youngest layer they cut through.
D. Rock layers that have been overturned are oldest from the base to the surface.
Answer:
C. Faults are younger than the youngest layer they cut through.
Explanation:
A. Intrusive rock is older than the surrounding rock layers. WRONG. The intrusive rocks are those that solidify underground and always form after the ones around them. So they are younger than the surrounding rocks.
B. A fold is older than the oldest rock layer it contains. WRONG. First, layers are set, and then, it occurs the folding. The folding is always younger than the involved layers.
C. Faults are younger than the youngest layer they cut through. RIGHT. A fault is a cut through different layers that occurs when the sedimentary rock breaks transversally. It occurs always after the sedimentary rock is already formed. So the fault is always younger than all the layers it cuts through.
D. Rock layers that have been overturned are oldest from the base to the surface. WRONG. If overturned, according to the superposition low, layers are oldest from the surface to the base. Superposition law states that during the sedimentary rock formation, the oldest layer is always that one at the bottom, while the younger layer is the higher one.

The site which responds to the hormone?
Answer:
Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone.
Answer:
According to toppr
Receptors are specific proteins located on target tissues to which specific hormones bind to produce their effect.
Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex. Formation of Hormone-Receptor complex leads to certain biochemical changes in the target tissue.
Hence Receptor site responds to a hormone.
So, the correct answer is 'Receptor'.

Which region of the Ig molecule interacts with the antigen? What makes the region suited for this purpose?
Answer and Explanation:
Immunoglobulins (Ig) are proteins that are composed of 4 polypeptidic chains: 2 heavy chains (H) and two light chains (L). They assemble in a structure with a 'Y' form. This structure has two regions: the Fab region and the Fc region.
The region of Ig which interacts with the antigen is the Fab region. That is possible because the Fab region presents variability in the amino acid sequence which determines the specific complementary shape with the antigen structure (like a lock and the key).

Which primer would most likely cause the results in the gel shown below?
(Any STRs preset are highlighted in red on the images below.)
Answer:
Primer 2
Explanation:
The lanes on the gel are all smeared and there is no distinct band. This indicates that many DNA segments, all of different sizes, were created in the PCR process. If at least one primer is within an STR region, the primer can bind to more than one position along the region, resulting in segments of variable lengths. Of the four sets of primers shown, only the primers in image 2 are inside the STR region.

a car acceleration from a 10 m/s to 60 m/s in 12 seconds. what is the acceleration
Answer:
4.167 m/s^2
Explanation:
vi = initial velocity = 10 m/s
vf = final velocity = 60 m/s
t = time = 12 s
a = acceleration, unknown
Use the following equation to find a:
(vf - vi)/t = a
(60 - 10)/12 = 4.167 m/s^2
4.167 m/s^2 = a
