What are the functions of guard cells?
Guard cells control the opening and closing of the stomata in plant cells.
WHAT ARE GUARD CELLS:Guard cells are structures that surrounds the stomata of plant cells and regulates the opening and closing of the stomata. The stomata, which are located on the leaves of plants opens in order for the plant to perform gaseous exchange i.e. intake of CO2 and release of O2.Therefore, Guard cells function to control the opening and closing of the stomata in plant cells.

Birds and insects both have wings, but we do not consider this similarity as evidence of relatedness because ____.
The wings in birds and insects are not considered as evidence of relatedness because they differ in structures even though their functions may be the same.
Organs in different organisms that are different in structures but similar in functions are referred to as analogous organs. Even though analogous organs serve as evidence of organic evolution, they are indications that organisms differ in the paths taken to evolve.
Some other organs may be similar in structures but different in functions. These types of organs are known as homologous organs and are indications that organisms are kind of related in the path taken to evolve.

the diagram shows two cells found in human blood.
a. the actual diagram of
red blood cell is 0.007mm ( 7 um) in diameter.
Calculate the magnification of the diagram. show your working.
side note: I measured it in a ruler and it's 2.3 cm = 23 mm (drawn to scale)
a)
Actual diameter = 0.007 mm
Diameter of scaled diagram = 2.3 cm = 23 mm
Formula to use:
Magnification = scaled dimension/actual dimension
Magnification = 23/0.007
Magnification = 3285.714... → x3286
b)
Red blood cells (RBCs), otherwise known as erythrocytes, don't have nuclei and organelles such as mitochondria, are smaller than WBCs and have a biconcave disc shape ideal for purpose
c)
i.
RBCs transport oxygen inhaled into the lungs around the body to all tissues and organs
ii.
RBCs are void of organelles so they are maximally packed with haemoglobin to bind and transport oxygen;
The biconcave disc shape is ideal for flowing through the blood vessels, particularly the capillaries, optimising them for transporting oxygen;
The small size also helps in being able to circulate the vasculature effectively and successfully

Immediately after a forest fire, the primary consumers in the area will compete most for which biotic factor?
In a freshly burnt forest, primary consumers will compete for forages with themselves.
Primary consumers are organisms that feed on producers.

Who are Primary consumers?
Primary consumers are herbivores, feeding on plants.Caterpillars, insects are examples of primary consumers because they only eat autotrophs (plants). Primary consumers are organisms that feed on producers.When a forest is lost to fire, most of the plants (the producers) are lost. A major energy pathway is eradicated, reducing system productivity and shifting importance to energy supplied by primary producers.

Answer:
the first blank is biodiversity. I think like that
The place where a group of organisms lives is called the habitat. The combination of the community and habitat is called the ecosystem.
What is habitat and ecosystem?An ecosystem is basically the neighborhood where animal lives. The habitat is the animal's address in that neighborhood. Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.
Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.
Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

Given that breaking bonds requires energy and forming bonds releases energy, explain how we know that cellular respiration releases energy overall?
because it's overall final fee energy value is less than it's initial, meaning that it has a negative free energy amount. therefore, there is a net release of energy in cellular respiration, so we know it releases more energy than it invests into the bonds of its products.

Would a light source be considered an internal or external stimulus?
For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.
What is stimulus?A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.
An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.
Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.
A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.
Thus, it can be concluded that light is an external stimulus.
