Answer:
Breeze. The formation of sea and land breeze form the classic examples of convection. Going by the definition of convection, the molecules at a higher temperature displace the ones at a lower temperature. Similarly, in the afternoon, the surface of the land near the sea is warmer as compared to in the evening.

The lightbulb part of the circuit is consider the "load"
What is simple circuit?
A simple circuit is a circuit that contains the three basic components needed for an electric circuit to function. The three basic components are a source of voltage, a conductive path, and a resistor.
When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.
Hence, option C is correct.

24. Name two types of pathways that help a body maintain homeostasis, and an example of each.
B
I
U
Font Family
Answer:
See the answer below
Explanation:
Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways
Negative feedbacksPositive feedbacksNegative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat
Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
Which stem cells are embryonic and which are adult?
Answer:
Embryonic stem cells can be readily grown in culture and exhibit unique properties, including spontaneous differentiation into three germ layers in vitro or teratoma formation in vivo. In contrast, adult stem cells are rare, undifferentiated cells present in many adult tissues.

If a student tested the bubbles collected in the test tube what would they find they are made of and how do you know?
Hello. This question is incomplete. The full question is:
A student prepared two beakers with identical sprigs of a water plant as shown below. She placed Beaker A in the shade and the Beaker B beside a fluorescent lamp. She then systematically changed the distance from the beaker to the lamp. She counted the bubbles given off by the plants in each beaker.
If the student later tested the bubbles collected in the test tube, What would she find they are made of?
Answer:
oxygen
Explanation:
The bubbles are oxygen and we can say that because this is the gas that plants release through photosynthesis. In this case, we can also confirm that the plant that was exposed to fluorescent light, showed more bubbles than the other plant, since the light allowed the photosynthetic rate of this plant to be higher, releasing more oxygen to the environment.

How is phosphorus NOT returned to the abiotic portion of the environment?
A. Death and
decomposition
B.animal waste
C. Fertilizer use
D.acid rain
Answer:
D) acid rain
Explanation:
Phosphorus is not returned to the abiotic portion of the environment through d. acid rain.
Abiotic portion of the environment are the nonliving components such as soil, water, or air.
Phosphorus is an essential element in any ecosystem that supports life and the functioning of the ecosystem. Phosphorus is used and returned into an ecosystem through various means in the phosphorus cycle.
Animals and plants are composed of phosphorus. When they die and decompose, phosphorus is returned to the aortic portion of the environment. Also, it is returned via the waste of animals.
Fertilizers containing phosphorus also add phosphorus back to the abiotic portion of the environment.
Acid rain occurs when Sulphur dioxide and nitrogen oxides mix and interact with oxygen and water in the atmosphere to form acidic compounds released as precipitation to the environment.
Therefore, phosphorus is NOT returned to the abiotic portion of the environment through d. acid rain.

Briefly explain the three clues that suggest that bacteria are an evolutionary success story
Answer:
The evolutionary success of this group results from its 1- small size, 2- simplicity and 3- fast reproduction rate
Explanation:
Bacteria are evolutionarily successful organisms that makeup about 15 percent of all biomass on Earth, and they occupy almost all habitats in nature. The small size of these unicellular organisms facilitates the exchange of nutrients and waste products with the surrounding environment. In addition, the relative simplicity of bacteria also facilitates the assembly of cell structures as well as a fast reproduction rate by the fast division of single cells. All these features are critical in order to understand the rapid evolution rate observed in this group.
