A strand of DNA contains the sequence GGC-CAT. What is the complementary strand of mRNA for this sequence?

Answers

Answer 1
Answer: CCG-GUA is the mRNA                  
Answer 2
Answer: CCG-GUA :) (because its an mRNA strand it can't have the amino acid Thymine or (T) so we replace it with a U.

The movement of H+ through the ATP synthase is best described as an example of __________. The movement of H+ through the ATP synthase is best described as an example of __________. simple diffusion hydrolysis active transport facilitated diffusion

Answers

Answer:

Facilitated diffusion

Explanation:

Oxidative phosphorylation, involving the Electron transport chain and Chemiosmosis is the third stage of cellular respiration. The main purpose of the ETC is to build an electrochemical (electrical and concentration) gradient across the inner mitochondrial membrane. It does this by using energy to pump protons (H+ ions) from the matrix to the inter-membrane space of the mitochondria.

Facilitated diffusion, also known as passive transport through channels, is a form of facilitated transport involving a passive movement of molecules along their concentration gradient, through channels called membrane proteins.

During Chemiosmosis of Oxidative phosphorylation, protons (H+) flow back down their concentration gradient (from inter-membrane space to matrix) due to the chemiosmotic gradient that has been formed in ETC. However, hydrogen ions (H+) cannot pass through the inner mitochondrial membrane except through an enzyme (protein) found in the inner mitochondrial membrane called ATP synthase. This protein acts as a machine powered by the force of the H+ diffusing through it, down an electrochemical gradient. This movement of H+ via ATP synthase further catalyzes the conversion of ADP to ATP.

It is an example of facilitated diffusion because H+ ions are diffusing across the inner mitochondrial membrane (from inter-membrane space to matrix) via a protein channel or membrane protein called ATP synthase.

A researcher conducted crosses between two different strains of Drosophila. When true-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) and vestigial wings (l), all F1 offspring had normal wings and normal bristles. The F1 offspring were crossed to flies with singed bristles and vestigial wings. Which F2 offspring is/are recombinant? (A) Singed bristles/vestigial wings only
(B) Singed bristles/normal wings only
(C) Singed bristles/normal wings and normal bristles/vestigial wings
(D) Singed bristles/vestigial wings and normal bristles/normal wings

Answers

Answer:

Singed bristles/vestigial wings and normal bristles/normal wings

Explanation:

The recombinant progeny might occur due to the crossing over of the homologous chromosomes in case of the  linked genes. This progeny are different from their parent progeny.

The F1 offspring obtained from the given cross in the question results in the normal wings and normal bristles ( SsLl). This progeny was crossed with singed bristles and vestigial wings (ssll). The progeny obtained from their cross are 'Sl' and 'sL' ( parental type ) and SL' or 'sl' ( recombinant).

Thus, the correct answer is option (D).

Without wildfires, forest ecosystems would be more likely to suffer from outbreaks of plant disease. please select the best answer from the choices provided t f

Answers

The answer would be: True

Forest ecosystem has a high density of plants. When an infectious plant disease appears, it will be easily spread as the trees are placed close to each other. You could say that the spreading mechanism of wildfire is similar to the disease because it is easier in the high-density area.

Answer:True.

Explanation: The wildfires has many positive aspects as compared to its negative ones. The forest fire can be a result of human activities or it can be due to natural sources.

The forest fire helps in removing the soil contamination and hence prevents the plant disease. Though it eradicated the animals and loss of habitat takes place but besides this there are many more advantages of forest fire.

It helps in removal of the diseased plants and harmful insects that spreads diseases.

Answers

The answer is sunlight, chlorophyll, carbon dioxide and water.

In the photosynthesis plants use sunlight as an energy and convert it into chemical energy stored in carbohydrates. Carbon dioxide and water are used for carbohydrate synthesis. This process occurs in the chloroplasts containing chlorophyll, which is necessary for absorbing energy from sunlight.

Select all that apply. An ecosystem could probably survive without _____.

carnivores
producers
Sun
water
herbivores
climate
soil
decomposers

I feel like this is a trick question but I can't figure it out.

Answers

Answer:

Carnivores

Explanation:

There are five basic components without which an ecosystem could not survive -

  1. energy,
  2. mineral nutrients,
  3. water,
  4. oxygen, and
  5. living organisms.

The entire energy of an ecosystem comes from  the sun, thus sun is essential. Similarly , water and climate is also essential. Water provides the free electron  during the photosynthesis reaction and fair climate ensures visibility of sun. Producers produce food which is consumed by herbivores , thus both plants and herbivores are important. Plant takes nutrients from soil thus soil is also important. Now if carnivores are removed from the ecosystem, then herbivores will die naturally and their dead bodies will be decomposed by the decomposers.

Thus, without carnivores an ecosystem could probably survive.

All of the following biotic and abiotic factors are necessary to an ecosystems ability to function.
