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.

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.

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.

Answer:

Explanation:

The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.

Answer:

These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

Explanation:

According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.

Answer:

7. Substitution mutation

8. Substitution mutation

9. Frameshift mutation

Explanation:

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.

Answer:

Plants uses carbon dioxide during photosynthesis. Plants use carbon to make carbohydrates and cellulose. Animals then eat plants and carbon is passed down. Animals then respire and release carbon dioxide into the atmosphere.

Answer:

both animals and plants are eukaryotic cells

Answer:

Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

Explantion

Animal cells

Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:

Nucleus – This contains genetic material (DNA), and controls the cell's activity.

Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.

Cytoplasm – A jelly-like substance where the chemical reactions happen.

Mitochondria – This is where energy is released from the food molecules

Plant cells

Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:

Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.

Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.

Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.

Explanation:

Answer: unconditioned stimulus = dancing bear

unconditioned response = baby turns head

conditioned stimulus = red circle

conditioned response = baby turns head

neutral stimulus = red circle

response to neutral stimulus = baby does not turn head

Explanation:

The unconditioned stimulus is the stimulus that occurs naturally without any prior learning.

The unconditioned response refers to an unlearned response which happens naturally and which occurs due to the unconditioned stimulus.

The conditioned stimulus is the stimulus that occurs due to prior learning and the conditioned response follows.

Based on the above definition, the answers to the questions will be:

• unconditioned stimulus = dancing bear

• unconditioned response = baby turns head

• conditioned stimulus = red circle

• conditioned response = baby turns head

• neutral stimulus = red circle

• response to neutral stimulus = baby does not turn head

Answer: Exponential

Explanation:

The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.

This is what happened with humans during the Neolithic Revolution when we began farming.

The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.

Answer:

Exponential growth

Explanation:

Without any competition for food or space, the butterfly species likely experienced exponential growth.

The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.

So, they most likely exhibited exponential growth.

Answer:

The answer is C. Photosynthesis uses some of the carbon dioxide released during the day.

Explanation:

Answer:

Reproduction is one of the most important characteristics of living beings, because -

- The existence of any species is dependent on the reproduction because no living being is immortal.

After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.

And,the birth of newborns of next generation is only possible by the reproduction.

- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.

- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.

And as mentioned before,these newborns are only possible due to reproduction.

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.
