Answer:
The stomata open to allow carbon dioxide to enter the leaves.
Explanation:
Higher plants are made up of two major system parts namely: shoot system and root system. The shoot system constitutes every part of the plant above the ground i.e leaves, fruits, stem etc. while the root system constitutes the part below ground i.e the roots. The shoot system and root system, however, interacts in several ways to ensure that the plant functions optimally. The ways they interact include:
- The roots (root system) absorb water from the soil, which is transported upwards to prevent leaves (shoot system) from drying up.
- The phloem, which is a conducting tissue, transports sugars (product of photosynthesis) from the leaves (shoot system) to the root nodules (root system) for storage.
- Nutrients are absorbed from the soil by the roots (root system) and moved to the stems (shoot system).
Note that, although it is true that "stomata in the leaves open to allow carbon dioxide to enter the leaves", there is no connection between the shoot and root system.
No.
It contains living cells (temporarily), but neither the cells nor the petal fit the definition of an organism: "any complete and entire living thing capable of carrying out all the processes necessary for life."
Answer:
White
Explanation:
Some times when we look at some objects they appear to be different in color to us than their actual color. It may be due to several wavelength of light with different intensities is striking on our eye.
Remember, white is not a color it is just produced in response to combination of 3 or more than three colors like light.
The three colors that can be combined at full intensity to form a white color are called as primary colors. The most common set is
Red+Green+Blue= white
Zero intensity of each component gives darkest color and full intensity of any component give a white color.
Secondary colors can be produced by the addition of two colors such as;
Red+Green=Yellow
Red+Blue=Magneta
Green+Blue=Cyan
The question is stated incorrectly. The correct question is as follows;
The site of intercellular communication between a neuron and another cell is the.
Answer:
Synapse.
Explanation:
Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.
Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.
Thus, the correct answer is synapse.
The list which correctly summarizes the main functions of proteins in the human body is the last one - p<span>owering movement, structural support, hormone production, antibody and enzyme production.
Skeletal muscles are responsible for movement and those muscles are made of protein. </span>
