The Center for Disease Control and Prevention recommended that men infected with Zika virus delay planned pregnancies. What is the recommended length of time for delayed conception for men afflicted with Zika virus?
Answer:
This should be 6 months
Explanation:
Generally ZiKa disease is caused by Zika virus,It is transmitted by Aedes mosquito as vector.It symptoms(rashes,fever,joint pains) are mild in the first week,but very severe in pregnant women.Men who visited then endemic region are advised to delay intercourse for 3 months,while those who were infected were recommended to abstain from sex for 6 months,
This is because the virus has been found in the semen longer than other body fluids.it has been found in infected semen for 180 days after healing.
In infected pregnant women,this can be transmitted to the fetus,causing microcephaly in the unborn child,Protection against mosquito bites is best way of prevention.
In exposed lady the period of abstinence should be 2 months.

What are digestive enzymes? Give three examples of digestive enzymes and briefly describe their specific functions.
Answer:
Digestive enzymes are the natural substances our body needs to help break down and digest food
We have three main digestive enzymes :
Proteases: These enzymes break down protein into small peptides and amino acids.
Lipases: break down fat into three fatty acids plus a glycerol molecule.
Amylases: Are responsible for breaking down carbs like starch into simple sugars.
Explanation:
Digestive enzymes are proteins that catalyze mainly hydrolysis reactions that make nutrients absorbable in the digestive tract. Pepsin is a gastric enzyme that turns proteins into albumoses and peptones which are shorter peptide chains that are then hydrolyzed to even shorter chains until amino acids by intestinal enzymes. Pancreatic amylase is an enzyme that turns starch(a polysaccharide) into maltose(a disaccharide). Lipase is present in the gastric juice, the pancreatic juice, and the intestinal juice. This enzyme catalyzes the hydrolysis of lipids(mainly triglycerides) into fatty acids and glycerol. When incomplete hydrolysis occurs triglycerides can become monoglycerides.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle and combines with a 4-carbon compound to form citric acid. During the citric acid cycle, what happens to acetyl-CoA? It enters the citric acid cycle and gains carbon dioxide to form citric acid, and gains more carbon dioxide through redox reactions to form a 4-carbon molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule. It enters glycolysis and associates with a 5-carbon molecule through redox reactions, forming another acetyl-CoA molecule. It enters the citric acid cycle and associates with a 4-carbon molecule, forming a 5-carbon compound, and then through oxidation reactions regenerates the 4-carbon molecule.
Answer:
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Explanation:
Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
In the citric acid cycle, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).
--------------------
The resumed steps of the Citric acid cycle are as follows,
1) Acetyl CoA joins an oxaloacetate molecule, which is a 4C molecule. They release the CoA group and form a 6C molecule called Citrate.
Acetil CoA + Oxalacetato → Citrato + CoA group
2) Citrate turns into an isomere Isocitrate
3) Isocitrate oxidates and release 1 CO₂ molecule, producing an α- ketoglutarate molecule -this is a 5C molecule-. Meanwhile, NAD+ reduces to NADH.
Isocitrate + NAD+ → α-cetoglutarate + CO₂ + NADH
4) α-ketoglutarate oxidates and release 1 CO₂ molecule, producing a 4C molecule, which joins a Coenzyme A producing Succinyl-CoA. Meanwhile, NAD+ reduces to NADH.
α-cetoglutarate + NAD+ → 4C molecule + CO₂ + NADH
4C molecule + Coenzyme A → Succinil-CoA
5) CoA from Succinyl-CoA is substituted with a phosphate group, which then forms ATP. The final product is Succinate and ATP
Succinyl-CoA + Phosphate group + ADP → Succinate + ATP + CoA
6) Succinate oxidizes and forms Fumarate, a 4C molecule. FAD+ forms FAH₂
Succinate + FAD+ → Fumarate + FADH₂
7) A water molecule and Fumarate produce Malate, which is another 4C molecule
Fumarate + H₂O → Malate
8) Finally, malate oxidizes and oxalacetate regenerates -the initial 4C compound-. NAD+ reduces to NADH.
Malato + NAD+ → Oxalacetate + NADH
So, when acetyl-CoA enters the cycle, it associates with a 4-carbon molecule (Oxalacetate), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule (Oxalacetate).

A storm brings two formerly separated populations of beetles together. They look very similar. Under the biological species concept, which of the following would show that the two populations are different species?
A. One population breeds in spring, the other in fall.
B. Males of the two populations have different flight patterns in courtship.
C. When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch.
D. All of the above is correct.
E. None of the above is correct.
Answer:
The correct option is D: All of the above is correct.
Explanation:
The biological species concept says that species are population groups that, in a real or potential way, can reproduce among each other and that are reproductively isolated from other groups.
Individuals belonging to a species cannot mate with members of other species, and if they do there is not any reproductive success.
The mechanisms of reproductive isolation might be divided in prezygotic and postzygotic.
Prezygotic or Premating mechanisms:
Ecological or due to habitat isolationSeasonal or temporal. This is the case described in option A "One population breeds in spring, the other in fall". These species are reproductively isolated because they differ in their breeding season.Sexual or ethological. This is the case described in option B "Males of the two populations have different flight patterns in courtship". Males belonging to each species behave differently during courtship. MechanicalGametes incompatibilityZygotic or Postmating Mechanisms:
Hybrid inviability. This is the case described in option C which states that "When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch". Eggs fail to hatch because the zygote is inviable. Hybrid sterilityHybrid decreased fertilityidentify the sphere wher life first emerged on earth hydrosphere, lithosphere, atmossphere

Answer:
you're answer would be hydrosphere
Explanation:
Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.

List some characteristics of each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. Primary wave: Secondary wave: Love wave: Rayleigh wave:
Answer:
The primary wave or the P wave is the fastest kind of seismic wave. These waves can travel through the fluids like the liquid or the water layers of the Earth, and solids rocks. It pulls and pushes the rock it moves through similar to the sound waves that pull and pushes the air. These waves are also called compressional waves, due to the pulling and pushing they do.
The secondary wave is also known as the S wave is slower in comparison to a P wave, and possess the tendency to move through the solid rock, however, not through any kind of liquid medium. The characteristic of the S wave helped seismologists to conclude that the outer core of the Earth is a liquid. The S waves help in moving the particles of rock side to side perpendicular to the direction of the wave or up and down.
The Love wave and Rayleigh waves are the two kinds of surface waves. These waves possess lower frequency in comparison to the P and S waves. Of the surface waves, the Love waves are the fastest surface wave and move the ground from side to side.
On the other hand, a Rayleigh wave rolls around the ground similar to the rolling of the waves across an ocean or a lake. Both these waves only travel through a solid medium.

what are chloroplasts? why are they green? how is the green colour plant of a great importance to the whole living world? explain?
Answer:
Chloroplasts are structures found in the cytoplasm of plant cells that are the site for photosynthesis. They are green because they contain a pigment called chlorophyll. Chlorophyll absorbs light to bring about the photosynthesis reaction. Light energy is crucial to initiate photosynthesis.
Photosynthesis allows the plant to convert carbon dioxide from air and water absorbed from the roots into oxygen and glucose, which are foods for plants. By releasing oxygen to air through photosynthesis, other living things can breathe in oxygen so that energy can be generated through another process, called respiration. Respiration is like the reverse reaction of photosynthesis, but it turns glucose to energy that supports living things.
Because plants also respire to generate energy, by using the glucose produced from photosynthesis, it also supports the food chain in the living world. Other organisms can consume plants for their energy.
In the end, chloroplasts and the chlorophyll inside are very important to the living world.
