Answer:

Carbon Dioxide limits photosynthesis at a concentration of around 400 ppm (ambient concentration) in low light.

Explanation:

Limiting factors affect the photosynthetic rate, decreasing the potential amount of carbohydrate made via photosynthesis. Carbon dioxide is essential to this form of biosynthesis- it provides the inorganic carbon that is integrated into carbohydrate molecules.

Carbon dioxide is typically present in the atmosphere at concentrations of 0.04%. Light intensity typically cause stomata to open, and increase CO2 uptake. Higher concentrations of CO2 up to 0.1%, cause dramatic increases in the photosynthetic rate.

Low light, thus means less stomatal opening, and less CO2 uptake. As low light intensity can be limiting, it lowers the concentration of Carbon dioxide at which the rate becomes constant.

gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job. For example, the wings of bats and birds.

This type of energy is thought of as motion. What type of energy is present? 1 point

MatroZZZ [7]

kinetic energy

The energy associated with an object's motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy. Another example of kinetic energy is the energy associated with the constant, random bouncing of atoms or molecules.

What would be the pros and cons of using Linnean and modern classification system?

Anna71 [15]

#1) What would be the pros and cons of using Linnean and modern classification system?

Answer: The pros of using the Linnean classification system is that it conveys a very detailed information about the species and the closest relatives of living things. It helps scientists to understand the complex relationships. A con is that it takes a very large amount of information and time for this system to develop.

I hope it helps, Regards.
