The  scientists Jean Baptiste Lamark and Charles Darwin approached evolution from different perspectives.

What is evolution?

The term evolution has to do with the emergence new species via natural selection. We shall now try to answer the questions individually;

1) The pair of oragnsims which are least related to each other are humans and wheat

2) The best test to show the relatedness of organisms is  Similarity in genomic DNA

3) The flipper of a whale and forelimb of a cat shows a correct example of homologous structures

4) The evolution evidence that  deals with structures common in embryos that form differently or for different purposes in adult form is called comparing anatomy.

5) The long neck of giraffe as compared to its ancestors is explained by the Inheritance of acquired characters theory.

6) The statement; "In the struggle for existence, the fittest would survive" is attributed to Charles Darwin

7) The scientist that observed the variation of organisms in Galapagos Island is Charles Darwin

8) The theory of acquired traits was proposed by Jean Baptiste de Lamarck.

9) The concept of overproduction states that having many offspring increases the chance that some of them will survive.

10) The ability of an  organism to survive and produce offspring is called fitness.

Which coast of north America has the greater amount of earthquakes, volcanoes and mountain s?

Answers

Answer:

There are more earthquakes on the West coast of the United States, because the boundaries of the North American, Pacific, and Juan de Fuca tectonic plates are located there. As the edges of the plates slide past or are forced under each other, the movement creates earthquakes

Explain why insect farming is more sustainable than raising large livestock, such as cattle or chickens. Do you think more Americans will embrace the idea of eating insects? Why or why not?

Answers

Answer:

The major environmental advantages of insect farming compared to livestock production are as follows: (1) less land and water is required; (2) greenhouse gas emissions are lower; (3) insects have high feed conversion efficiencies; (4) insects can transform low-value organic by-products into high-quality food or feed.

Insects release fewer greenhouse gases than traditional livestock. Rearing traditional livestock accounts for 18% of greenhouse gas emissions (pdf, p . 63), which trumps emissions by the transportation industry. ... Insects also release much less ammonia and methane than pigs and cattle.

I think they should not genetically engineer babies because it is inhumane, they might as well make robots and forget about humans. Sadly I think one day we will, if they are able to implant a baby in a woman, they will soon be able to make a baby without a womb.

Answer:

I don't think we should "engineer" babies, they have their own life and changing that to make another that God did not make will turn out weird.  God creates the babies, only he can make them perfect.  But sadly, yes, I think people will try to "engineer" babies.

How are the products and reactants of photosynthesis and cellular respiration related?

Answers

The reactants of photosynthesis include CO2, H2O, and sunlight. The products are O2 and glucose (C6H12O6). The reactants of cellular respiration are O2 and glucose (C6H12O6) which get turned into CO2, H2O, and energy. They related because of the cycle created by photosynthesis and cellular respiration. As photosynthesis makes O2 and glucose, cellular respiration then takes that and turns it into CO2 and H2O that are then transformed again through photosynthesis.

The formation of food by trapping the sunlight is called photosynthesis. The digestion of the food to get the energy in the presence of oxygen is called respiration.

These two processes are interrelated with each other because the product of photosynthesis is glucose which is made up of carbon dioxide and oxygen.

In respiration, the cell uses the molecule which is made in the process of photosynthesis that is glucose. It breakdown into its monomer and give the energy.

Hence, In this way, these reactions are inter- related.
