Check each of the following statements that are true with regard to Griffith’s experiments.a. ______ Griffith discovered transformation in bacteria.b. ______ Mice injected with smooth bacteria quickly became sick and died.c. ______ Encapsulated bacteria can become "naked" bacteria.d. ______ Bacteria that do not have capsules tend to be harmless.e. ______ Smooth bacteria develop a capsule only after exposure to the DNA of encapsulated (rough) bacteria.f. ______ Griffith’s transforming factor was the protein in the capsule.g. ______ Transformation allows bacteria to acquire new genes.h. ______ Enzymes that destroyed DNA would prevent transformation.

Answers

Answer:

The correct answer is - a, d, e, h, i.

Explanation:

Frederick Griffith performed an experiment of 1928 known as Griffith's experiment and showed that bacteria can get genetic material through a process called transformation.

The following statements are true:

Griffith found out transformation in bacteria.

Bacteria that are naked or smooth tend to be harmless.

Enzymes treated bacteria that destroyed DNA would prevent transformation.

Transformation allows bacteria to acquire new genes.

Naked or smooth bacteria can make them self encapsulated only after exposure to the DNA of encapsulated bacteria.

which best describes the concept of natural selection?

A. an organism will always mutate to survive
B. The fittest organisms are selected for
C. Nature selects the organisms with the most Mutations
D. mutations make organisms more fit

Answers

Answer:

D.

Explanation:

Natural selection is the way that organisms adapt through adaptations to better survive and pass on the special genes which enable the offspring to survive. Saying an organism will always mutate to survive is wrong, as natural selection implies that not all organisms survive. With natural selection, nothing is "selected", so B and C are not correct. However, mutations DO make organisms "more fit" to survive their environments, so D is the answer.

Answer: The fittest Organisms are selected for

what seven elements have the appearance and properties of a metal but behave like the non-metal in certain situations?

Answers

Answer:

i. boron

ii. silicon

iii. germanium

iv. arsenic

v. antimony

vi. tellurium

vii. polonium

Explanation:

Elements that have appearance and properties of a metal but behave like non-metal in certain conditions are called semi-metals or metalloids. On the periodic table, they are found between metals and non-metals. Examples are astatine, polonium, tellurium, antimony, arsenic, germanium, silicon, boron.

Some of their properties that make them look like metals are:

i. They exist as solids at room temperature.

ii. They are shiny.

iii. They are ductile.

Some of their properties that make them look like non-metals are:

i. They are brittle.

ii. Not very good conductor of electricity compared to metals.

The seven elements have the appearance and properties of metal but behave like non-metal in certain situations.

The MAP kinase pathway is activated by ligand binding to a transmembrane receptor, which switches Ras on via GEF (Guanine nucleotide Exchange Factor) that counteracts GAP (GTPase Activating Protein) activity. Ras-GTP in turn activates the downstream signaling intermediates (kinases), which are activated by sequential phosphorylation. Which drug CANNOT be used to target cancer cells that have elevated receptor activation

Answers

Answer:

Inhibitor molecules that interfere with GAP activity

Explanation:

The mitogen-activated protein kinase (MAPK) is a pathway composed of proteins that amplify and integrate signals from receptors localized on the surface of cells and trigger the transcription of specific genes in the nucleus of the cell. In eukaryotic organisms, the MAPK pathway is known to control critical cellular processes such as, for example, cell proliferation, cell differentiation, cell death, etc. RAS proteins are GTPases localized to the plasma membrane involved in MAPK signaling. Moreover, the GTPase activating proteins such as RasGAP (Ras GTPase activating protein) regulate Ras-GTP bound by promoting GTP hydrolysis. It has been shown that RasGAP expression is down-regulated in different types of cancer. In this regard, it has been proposed that the interference of GAP activity should result in an enhanced Ras protein activation in cancer cells, thereby initiating tumorigenesis by inducing, for example, uncontrolled cell proliferation.
