A. positive, negative

B. negative, positive

C. neutral, positive

D. neutral, negative

Answers

Answer 1

Answer:

option c

Explanation:

Answer 2

The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.

What is polarity?

The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.

Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.

The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.

Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.

Answers

The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.  

Explanation  

Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.

Explica como crees que se originó la vida sobre el planeta tierra

Answers

Sabemos que la vida comenzó hace al menos 3.500 millones de años, porque esa es la edad de las rocas más antiguas con evidencia fósil de vida en la tierra. Estas rocas son raras porque los procesos geológicos posteriores han remodelado la superficie de nuestro planeta, a menudo destruyendo rocas más viejas y creando otras nuevas (lo siento si es un amor incorrecto, marque como más inteligente si es correcto).
La pregunta del cómo empezó la vida en la Tierra es una de las más difíciles (e interesantes) que se pueden plantear. De hecho, el origen de los seres vivos encierra varias cuestiones clave: ¿cuándo ocurrió?, ¿pudo producirse más de una vez?, ¿cómo fue la transición entre la química y la biología?, ¿tuvo lugar en la Tierra o fuera de ella? Y, a medio camino entre la ciencia y la filosofía: ¿fue fruto del azar o de la necesidad?

La investigación experimental sobre el origen de la vida comenzó en la década de 1950, con el trabajo de dos científicos pioneros en una disciplina llamada química prebiótica: Stanley L. Miller y Joan Oró. Las pruebas acumuladas desde entonces nos indican que la vida probablemente comenzó hace unos 3.800 millones de años, sólo 700 millones de años después de la formación de nuestro planeta. En el gran laboratorio de química que era la Tierra primitiva se sintetizaron las primeras moléculas orgánicas, que fueron organizándose progresivamente para formar otras más largas y complejas.

Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.

Answers

Answer:

The answer is all of the above are correct.

Explanation:

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:  

CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

U A A G C U G A G C

Explanation:

The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).

But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).

Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:

A T T C G A C T C G

Translate:

U A A G C U G A G C

So, the complementary mRNA sequence will be U A A G C U G A G C

What cycle of replication is used by the common cold virus?
A: Dormant cycle
B: Replication cycle
C: Lytic cycle
D: Lysogenic cycle

Answers

Answer:

C

Explanation:

The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.

The common cold virus is replicated using the lytic cycle, by introducing its genome into the host and using its cellular machinery, hence option c is correct.

How common cold virus replicate?

The common cold virus is replicated by using the lytic cycle, in which the virus introduces its genome into the host genome and uses all the replicating machinery of the virus.

The lysogenic cycle is different from the lytic cycle in which the viral genome replicates on its own and does not integrate its genome into the host genome.

After replicating its genome with the host genome, the viral genome is excised from the host genome and assembled into new viral particles for infecting other host cells. The new viral particle lysed the host cell and spread to other cells.

Therefore lytic cycle is used by the common cold virus, hence option c is correct.

A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.

A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.

In the following sequences, mutation has occured as follows:

7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.

8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.

9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

Identify the incorrect statement regarding the fundamental causes of edema. Multiple Choice Capillary reabsorption does not depend on oncotic pressure. A deficiency of albumin (hypoproteinemia) produces edema by reducing the reabsorption of tissue fluid. Kidney failure leads to water retention and hypertension, thus raising capillary blood pressure and filtration rate. Obstruction of lymphatic vessels can interfere with fluid drainage and lead to the accumulation of tissue fluid distal to the obstruction. Since albumin is produced by the liver, liver diseases, such as cirrhosis, tend to lead to hypoproteinemia and edema.

Answers

Answer:

Capillary reabsorption does not depend on oncotic pressure

Explanation:

Edema refers to the swelling caused by the fluids trapped in the body's tissues, which swell from injury and/or inflammation. Edema can be associated with the decrease in plasma oncotic pressure, i.e., osmotic pressure exerted by proteins (especially albumin) in the blood vessel's plasma, the increase in hydrostatic pressure, or the increase in the capillary permeability. Moreover, capillary reabsorption refers to the movement of fluid from interstitial space to the capillaries, which is driven by the blood colloidal osmotic pressure. Lymphatic obstruction, i.e., the blockage of the lymph vessels that drain fluids from tissues, may cause edema in the part that is drained by the affected vessels (it is known as lymphedema). Moreover, liver/kidney failure may lead to edema by decreasing albumin and oncotic pressure. When plasma albumin levels drop because of liver diseases, the colloid osmotic pressure also decreases. In consequence, liver diseases, including stage 3 cirrhosis, lead to the development of swelling in the abdomen, thereby leading to edema.
