A protein isolated from a thermophilic bacterium shows a molecular weight of 160 kD when eluted from a size-exclusion chromatography column, but when the purified protein is run on an SDS-PAGE gel, a single band of 80 kD is observed.

Answers
Answer:
as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.

In one experiment, the heart rate of a mollusk at rest was measured at 0.3 cycles/s. How many times did the mollusk's heart beat in 1 min?
Answers
Answer:
18 times
Explanation:
Heart rate = 0.3 cycles/s
Heart rate = [tex]\frac{number of cycles}{time}[/tex]
number of cycles = heart rate x time
But, 1 min = 60 seconds
⇒ number of cycles = 0.3 x 60
= 18
Thus, the number of times that the Mollusk's heart beat in 1 min is 18.

Why do stems have bark? What does the phloem do?
Answers
Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

In one or two paragraphs, compare and contrast surface ocean currents and deep water ocean currents in terms of causes and characteristics.
Please!!!
Answers
Answer:
Surface ocean currents
Surface currents refer to movement of the top layer of ocean water. Surface water flows in to replace the sinking water, which in turn becomes cold and salty enough to sink.
examples of surface ocean currents are California Current (Cal) in the Pacific ocean basin and the Canary Current (Can) in the Atlantic ocean basin.
Deep ocean currents
Deep-water currents describe water movement patterns far below the ocean’s surface and the influence of the wind. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.
What describes gneiss?
Answers
Gneiss is a high grade metamorphic rock, meaning that it has been subjected to higher temperatures and pressures than schist. It is formed by the metamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representing alternating layers composed of different minerals.
Gneiss is a type of metamorphic rock that is formed by high pressure and temperature caused by the earth's surface.
What are metamorphic rocks?Metamorphic rocks are those rocks that are formed when other rocks are introduced under high temperatures and pressure that is exerted by the layers of the earth. There are three types of metamorphic rocks.
Since gneiss is a high-grade metamorphic rock, it has undergone more intense heat and pressure than schist. It is created through the transformation of sedimentary rock, such as granite.
Gneiss has distinctive foliation or alternate layers made of various minerals. This rock comes under the metamorphic regional type of rock.
Therefore, Gneiss rocks are those metamorphic rocks that are formed on convergent plate boundaries.

Imagine sperm and egg cells have 46 chromosomes like other cells in the body. That
is they have 46 chromosomes when a sperm cells fertilizes an egg cell. Would that
affect the total number of chromosomes in their offspring or children? Tell why or why
not.
Answers
Answer:
When an egg and sperm having 46 chromosomes similar to the body cells, their fertilization produces offsprings or children with 92 chromosomes which are double number of chromosomes as compared to parent cell. So they are not similar to parents. As we know that fertilization is the process of fusion of gametes and paring up of chromosomes. The offsprings are different from their parents in having more chromosome sets.

All cells come from parent cells that exchange DNA.
All living things are composed of single cells or multiple cells.
All cells grow and develop until they reach a certain size, at which point they die.
All cells are equipped with structures that enable motion, such as pseudopods or flagella.
Answers
Explanation: Since “The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.”
All living things are composed of single cells or multiple cells. Therefore, option B is correct.
What is cell theory?Cell theory is given by Schleiden and Schwann. According to this theory, cells make up every biological entity; they are the basic building block of life, and all life originates from earlier forms of life. Today, the cell idea has become one of the guiding concepts of biology due to its widespread acceptance.
A cell is the lowest form of life. This indicates that a cell cannot be divided into smaller units and yet be considered to be alive. An entire organism, such as a person, can be divided into smaller parts, such as organ systems, organs, and tissues.
Organisms can be unicellular or multicellular. Therefore, option B is correct.

All structures in an angiosperm seed are diploid. An angiosperm seed contains structures contributed by three generations of plants.
Answers
Answer:
An angiosperm seed contains structures contributed by three generations of plants.
Explanation:
The spermatophytes, also known as phanerogams, represent a group of seeded plants that have developed special structures for reproduction. This group (spermatophytes) consists of gymnosperms or 'naked seeds', and angiosperms or 'enclosed seeds'. The seed is an organ generated from the ovule after fertilization by the pollen grain, which gives rise to a seedling during the process of germination. In flowering plants, seeds are generated by a process of double fertilization and consist of three tissues: 1-an embryo (generally diploid) formed by repeated mitotic division of the zygote cell, 2- an endosperm tissue (generally triploid, 3n) that nourishes the embryo during its growth, and 3-a seed coat generated from the integuments of the ovule. In angiosperms, seeds consist of three generations: the gametophyte that provides nutrients to the embryo, the embryo, and the seed coat which is generated from the parental tissue (sporophyte).

Answers
Marine mammals are endothermic. I think that's the correct answer 'cause they can produce their own body heat (which therefore means that they are warm-blooded) and they can keep at a stable temperature even in harsh conditions. Plus, whales don't have gills b/c they are mammals (and mammals don't have gills), not all mammals have blubber (it's mainly penguins and seals), marine mammals can stay underwater for a long amount of time...but they eventually need to come up for air, and baleen acts like a "filter"; it "filter" and separates the water from the krill/microorganisms.

If the anticodon of a molecule of tRNA has the sequence GAU, what was the original DNA sequence?

Explanation:
DNA to RNa
A---> T
C--> G
RNa to dna
A--> U
C---> G
If the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
What is DNA sequencing?
DNA sequencing is defined as the laboratory procedure used to determine the exact sequence or order of the four building blocks or bases that make up DNA. Information that is stored in DNA in a code which is formed by arranging the four bases which are adenine, cytosine, guanine and thymine which are identified by letters A, C, G and T in different order.
Within double-stranded DNA, nitrogenous bases on one strand pair with complementary bases on the other strand. A always pairs with T, and C always pairs with G, during DNA replication, the two strands separate into a double helix.
Sequence of tRNA is GAU, so the DNA sequence is CTA as C complements to G, A to T and U to A as in RNA Uracil is present in the place of thymine.
Thus, if the anticodon of one molecule of tRNA contains the sequence GAU, then CTA was the original DNA sequence.
