The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)

A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.

Which statement is correct?
The speed of the light ray is the same in air and Medium A.

The speed of the light ray is the same in air and Medium B.

Medium A and Medium B have different densities because light refracts at different angles.

Medium A and Medium B have the same density because the light ray strikes both at the same angle.

Hippopotamuses live in Africa’s rivers and lakes. They’re herbivores and coexist with other herbivores and carnivores. Which action could lead to a decrease in the number of hippos?

Answers

Answer:

If any of the other carnivores are predator they might eat the hippos. If the other herbivores population incresses there food supply may drop. If there is a drought there habitat will be in danger. Pouchers are also a threat to this animal.

Explanation:

Maybe the decrease in plants they eat Otherwise known as deforestation

The Hippopotamuses lives in the river and lakes of Africa. They are herbivores and co exist with other herbivores and carnivores.

There can be two possible reasons for the decrease in the number of hippos.

The carnivores lion and hyena can eat the hippo(young hippos) which will reduce the number of hippos.

The other reason could be reduction in the number of plants that hippos eat.

9. UGU-UUC-CCU-UAA

Answers

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.

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.

Which is the difference between an antibiotic and an antiviral?

Answers

Answer:

There are no options in this question, the options are as follows:

A. Antibiotics build up immunity, and antivirals increase white blood cells.

B. Antibiotics treat the symptoms, and antivirals destroy the causing organism.

C. Antibiotics are in liquid form, and antivirals are in mist form.

D. Antibiotics treat patients who have Staphylococcus, and antivirals treat patients who have the flu.

The answer is D

Explanation:

Specific drugs are used to curb infection or diseases caused by specific pathogens. An infection can be caused by either bacteria, virus or fungi. Considering their different mechanism of infection, viral infections are treated with the use of ANTIVIRAL DRUGS while bacterial infections are treated with the use of ANTIBIOTICS.

According to this question, staphylococcus is a bacterial genus and hence, patients with staphylococcus can be treated with antibiotics while flu is a viral disease, hence can only be treated with antivirals.

If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?

Answers

Answer:

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

Why does climate change affect so many things?

Answers

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.

Los fósiles, una prueba de la evolucion. El estudio de los fósiles nos da una idea muy directa de los cambios que sufrieron las especies al transformarse unas en otras; existen muchas series de fósiles de plantas y animales que nos permiten reconstruir cómo se fueron adaptando a las cambiantes

Explanation:

Answer:

homologous: have identical position, value, or structure

Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.

 

Explanation:

The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).

In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

Answer:

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.
