What can the study of fossil pollen tell us about global climate change during the past 100,000 years?

Answers

The chemical structure of sporopollenin that covers most spores makes them stable and strong. Therefore, spores are well preserved even in sediments for those that settle and do not sprout. Thes spores vary (in size and shapes) by plants hence paleontologists use this uniqueness to determine the types of plants that grew in the past. By comparing those ancient plant with today's, they are able to extrapolate the changes in climate that resulted in the extinction of evolution of particular plants.

Why is it helpful to have lots of villi

Answers

Well, villi helps the intestine absorb, therefore, it helps the intestine absorb more nutrients. I hope this helps!
Functions of the Villi. We've already stated that the small intestine's main job is to absorb nutrients from the food you eat and that your villi help by increasing the surface area the intestine has for absorption.Sep 19, 2014

How did early eukaryotic cells benefit from the photosynthetic bacteria that took up residence within them?

Answers

Answer:

The eukaryotic cell were able to capture sunlight and produce energy(sugar) through photosynthesis.

Explanation:

According to the endosymbiotic theory a larger cell engulfed a smaller bacteria which can do photosynthesis and helped in the evolution of the eukaryotic cell. This evidence is seen in plant cells where chloroplast is present which shows similarities with prokaryotes.

The photosynthetic bacteria benefitted eukaryotic cells because the eukaryotic cell gained the ability to capture light energy and using light energy for the formation of energy molecules which is sugar and this process is called photosynthesis.

What are three factors that affect the rate at which photosynthesis occurs

Answers

The factors that affect the rate at which photosynthesis occurs are;

  • The intensity of light
  • Oxygen concentration
  • Temperature

Definition:

Photosynthesis put simply refers to a process by which plants manufacture their food in the presence of water, chlorophyll, sunlight, and CO2.

The photosynthesis process occurs mainly in the leaves of the plants.

Factors affecting rate at which photosynthesis are:

  • Temperature: Photosynthesis just like other biochemical reactions occurs best within a specific range of temperatures.

  • Light intensity: The amount of light required varies for different plants. Photosynthesis utilises up to 1.5 % of light at most in the process and so light is generally not a limiting factor at high intensity.

  • Oxygen: Optimum levels of oxygen are favourable for photosynthesis. Oxygen is needed for photorespiration in some plants and the major by-product of photorespiration is CO2 which is important for photosynthesis.
