What is the number of nuclear division in megaspore mother cell for the formation of a female gametophyte ?

Biology 3-4

Please give detailed answers. 3. Charles Darwin once described a flower that produced nectar at the bottom of a tube 25 centimeters (10.5 inches) deep. He predicated that there must be a moth or other animal with a 25-centimeters-long tongue to match, and he was right. Such specilization almost certainly means that this pa

Biology 1-2

Please provide detailed explanations. 1. The desert tends to have two catagories of plants: small grasses of herbs, and shrubs or small trees. The grasses and herbs typically have fibrous roots. The shrubs and trees have taproots. What advantages can you think of for each type of root? How does each type of root allow f

Photosynthesis and Respiration

Cellular Respiration and Photosynthesis co-exist as paired processes. Photosynthesis converts light energy into organic molecules such as carbohydrates. These molecules are picked up and utilized as fuel sources in organisms that employ Cellular Respiration for production of ATP and CO2. Although it appears that Photosynthesi

Oaks are pondered in terms of breeding.

The oak makes potentially nutritious seeds (acorns) that contain very bitter-tasting tannins. If we could breed the tannin out of acorns, they might become a delicacy. Why do you suppose we have failed to domesticate oaks?

Plant Biology: Identification and Function

Please view the attached file. 1. Is this plant a member of coniferophyta? 2. Provide the physiological and structural characteristics that allow the specimen collected to be classified as the represented phylum. 3. Discuss how this organism obtains and transports water 4. Discuss the acquisition and transportation of nutrient

Photosynthesis is discussed.

According to the statolith hypothesis the cells farther away from the earth elongate while those near the earth do not. true or false and why?

Auxin was applied to a cut apical shoot of a bean plant...

I did an experiment in lab---Auxin was applied to a cut apical shoot of a bean plant. What results should I expect to find regarding lateral bud growth (decrase or increase) and also the number of lateral buds(increase or decrease). Also would the presence of auxin applied in this manner affect the vertical growth of the plant?

Pasteur Effect, Glucose, Photosystem, and Other Short Answer Questions

1) Louis Pasteur (a French biochemist) investigated the metabolism of yeast which can survive under aerobic or anaerobic conditions. He observed that the yeast consumed sugar at a much faster rate under anaerobic conditions than it did under aerobic conditions. Explain this Pasteur effect. 2) If a plant is kept for many day

Photosynthesis and dense coverings

What happens to photosynthesis when there is a dense covering such as thick forests, clouds or dust from volcano eruptions. What happens to caron dioxide and oxygen levels. What test can be done in a lab? Also, Where can I find more online information.

AP Biology: Lab 5

OVERVIEW In this experiment you will work with seeds that are living but dormant. A seed contains an embryo plant and a food supply surrounded by a seed coat. When the necessary conditions are met, germination occurs and the rate of cellular respiration greatly increases. In this lab you will: 1. Measure oxygen consumption
