The exquisite complexity of traits such as the vertebrate eye seems to pose a problem for evolution by natural selection. How do

Answer:

The correct answer would be - complex eyes evolved in the gradual steps, each of which was fully functional and adaptive in improving visual acuity.

Explanation:

The natural selection of the complex traits such as the vertebrate eye (complex eye) are seems to be problematic, many biologist think that the complex eyes evolution is take place in gradual steps and each step of this evolution was adaptive and functional in improving the visual acuity.

The steps that were involved are like light sensitivity patch, a deepening hole or pit that help in sharp vision and many other random evolution steps.

Thus, the correct answer is- complex eyes evolved in the gradual steps, each step of this evolution was fully functional and adaptive that helps in improving visual acuity.

1. Define Chemosynthesis?

the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.

2. List some organisms that undergo Chemosynthesis?

Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.

3. Which organisms conduct photosynthesis?

Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

4. Define photosynthesis

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

5. Type out the chemical equation of photosynthesis?

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Usimov [2.4K]

Answer:

Blastocyst is an early embryonic stage in mammals otherwise it is a blastula which is followed by development of gastrula. Blastocyst is a hollow ball like structure that develops by repeated cell division from zygote . It is superficially covered by a layer of cells collectively termed trophoblast.

If you were going to study the effects of certain fertilizer on plant growth, which list of variables would you most likely want
sergey [27]

Answer:

a) Soil type  

b) Water quantity and quality

c) Intensity of light

d) Quantity and quality of fertilizer applied.  

e) Environmental condition

Explanation:

Fertilizer plays an essential role is providing the essential nutrients to plants thereby boosting their growth.  

Hence, in order to conduct a controlled experiment which shall monitor the impact of fertilizer on the growth of plants, all other factors which affect the growth of plants must be standardized or kept constant. These factors include -  

a) Soil type  

b) Water quantity and quality

c) Intensity of light

d) Quantity and quality of fertilizer applied.  

e) Environmental condition
