Convection currents can be described best by:
a. Hot air rising, cold air sinking
b. Cold water rising, hot water sinking
C. Random distribution of temperatures
d. Hot air sinking, cooler air rising
Answer:
A.Hot air rising,cold air sinking
Explanation:
Hot air rises in a confined or closed space.That is one of the reasons why firefighters have some people crawl on the flour to get out. the smoke is hot air so it rises to the ceiling of the room, while cold air stays lower.

Which type of energy change causes this leaf to grow? A. Thermal energy is transformed into potential energy. B. Thermal energy is transferred to the leaf. C. Electromagnetic energy is transformed into chemical energy. D. Electromagnetic energy is transferred to the leaf.
Answer:
C. Electromagnetic energy is transformed into chemical energy
Explanation:
Growth is one of the characteristics of living things. It refers to the increase of an organism. A leaf is part of a plant, which is a photosynthetic organism i.e. an organism capable of producing its own food using energy from sunlight. Light energy is a part of the ELECTROMAGNETIC ENERGY.
This light energy is used to synthesize glucose (food) via photosynthesis. The glucose, which stores chemical energy in its bond is then broken down to yield ATP used for growth. Hence, the transformation of electromagnetic energy to light energy is how a leaf grow.
it is C. Electromagnetic energy is transformed into chemical energy.
Glucose can be classified as both of the following terms
Answer:
hope this helps :)
Explanation:
Monosaccharides contain a single unit; disaccharides contain two sugar units; and polysaccharides contain many sugar units as in polymers - most contain glucose as the monosaccharide unit. Number of Carbons: Monosaccharides can be further classified by the number of carbons present.

Venus flytraps have leaves that have been modified to capture insects. Cacti have leaves modified into spines. How are these modified leaves classified?
A. Homologous structures
B. Analogous structures
C. Vestigial structures
D. Embryo development
Answer:
Answer is A, Homologous Structures
Explanation:
The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures. Option A is correct.
Homologous structures:
These are the structures in the different organisms that show similarities in the basic organization of the structure.
These organisms are from common ancestors, Homologous structures serve completely different functions.For example- The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants.Analogous structures are those structures that serve the same function but are from different ancestors.
Therefore, The insect-catching leaves of Venus flytrap and the and spiny leaves in cactus plants are classified as Homologous structures.

A researcher finds that males in two populations of bowerbirds make different types of structures to attract female birds. The males of population 1 build hut-shaped structures and decorate them with colorful objects. The males of population 2 loosely interweave sticks around a central pole and decorate it with dull-colored objects. Female bowerbirds prefer structures made by males of their own population.

In the study of cancer, researchers have used different types of cells, different environmental conditions, and different
experimental designs. But, all researchers have arrived at the same conclusion. What does this say about the
conclusion?
Answer: In study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. But, all researchers have arrived at the same conclusion that the study is well supported to cancer studies.
Explanation: This is because each cell behaves differently in different environmental conditions and each type of cell has its peculiar behaviour in different conditions.
So by this pattern varied studies can be done.

Explain the relationship between a hypothesis and a theory. Then give an example of something that would cause a hypothesis or a theory to be revised or discarded.
Answer:
Hypothesis is a written observation, that has not been proven correct, but is written after observation of a specimen. Proving this particular hypothesis, shows the interconnectivity/ relationship between a hypothesis and a theory.
Explanation:
Simply put, a hypothesis is a written observation, which may or may not be true, while a theory is established when a hypothesis is proven correct.
AN EXAMPLE OF SOMETHING THAT COULD MAKE A THEORY TO BE REVISED:
If other laws or theories put before it controversies it.If its observations where not correctly written.If it cannot stand the test of time.If further experiments doesn't show the same result.Hypothesis is either written or evidence based observation but it has to be proven where as when a hypothesis is proved by doing experiments multiple times and getting same results then it is called as as scientific theory.
What is scientific theory ?scientific theory can be a structured form where a group of facts can meet and be explained by using scientific hypothesis and laws, each theory can be proved by doing experiments and applying scientific method.
Scientist will design an experiment and conduct the experiment to test and prove that hypothesis; If the result of hypothesis is incorrect, then new hypothesis will be set and new experiment will begin.
If the result of hypothesis is correct, repeated tests have been done to ensure the accuracy of the result.

Plants like the stinging nettle seen here have sharp, needle-like hairs that inject a burning chemical into animals that touch the stems or leaves. These hairs are used for A) protection. B) reproduction. C) photosynthesis. D) attracting insects.
Answer:
A. Protection
Explanation:
These plants have this external protection system to protect them against being eaten by these animals.
In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.
The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals
