Answer:
The correct answer is
1. A rabbit living in a desert has long ears to disperse heat- abiotic factor.
2. A moth immediately dives to the ground when it hears a bat- biotic factor.
3. A lizard stays warm by sunning itself on a rock- abiotic factor.
4. A cactus has spines instead of leaves to help conserve water- abiotic factors.
5. A petunia is bright red to attract hummingbirds- biotic factor.
6. A stick-bug blends in with trees to hide from predators- biotic factor.
Explanation:-
The environment includes both abiotic and biotic factors which can affect the ecosystem. Living elements like plants and animals which affect ecosystem are known as biotic factors while the non-living elements which include air, water, temperature are called abiotic factors.
In the given question the options affected by the biotic factors due to bat, due to hummingbirds and due to predators.
Options affected by the abiotic factors due to heat and due to water.
Answer:
D
Explanation:
Because every system in the body is vital
Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).
Answer:
C. Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type's structure and function.
Explanation
Both of these are two types of specialized cells that make specific combinations of proteins, which allows them to have unique structures and functions.
