Answer:
The warmer water will mix with the cold water because it will migrate to the surface.
Explanation:
If hot water and cold water are poured in the same place, it means that they will occupy the same space. However, hot water has a lower density than cold water, which means that hot water molecules are lighter and will tend to rise towards the surface.
However, when migrating to the surface, the hot water molecules will pass between the cold water molecules, causing the two waters to mix. In this process, the hot water will transfer heat to the cold water and cool until the two waters have the same temperature.

Heat energy is transferred through solids, liquids, and gases. How is heat transferred throughout the world’s oceans?
A) The warmed atmosphere transfers energy as heat to the rivers and the energy is distributed by conduction to oceans.
B) Sunlight penetrates the ocean’s waters, evenly distributing energy as heat from the surface to the ocean floor.
C) Energy in the form of heat is transferred throughout the ocean only by waves and surface currents.
D) Convection currents are driven by sunlight warming surface waters, which flow throughout the oceans, distributing energy as heat.
Answer:
C) Energy in the form of heat is transferred throughout the ocean only by waves and surface currents.
Explanation:
Heat is transferred between the surface of a sea or ocean and the atmosphere through radiation, convection, and turbulent heat exchange and by means of the evaporation of water and condensation of water vapor above the sea or ocean.
If it's not C then my best guess would be D. This one is kind of tricky!!

One of the limitations of the light microscope is the _____.
Answer:
resolving power.Explanation:
The principal limitation of the light microscope is its resolving power.
Using an objective of NA 1.4, and green light of wavelength 500 nm, the resolution limit is ∼0.2 μm. This value may be approximately halved, with some inconvenience, using ultraviolet radiation of shorter wavelengths.

Describe the importance of Tiktaalik roseae to the study of evolution.
Answer:The discovery of well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins.
Explanation:can i have brainless?
Tiktaalik roseae was famous for his discovery of well-preserved pelves and a partial pelvic fin in aquatic organisms. These structures support aquatic organisms to a large extent.
What is Evolution?Evolution may be defined as a methodology through which gradual changes in organisms may take place over many generations. Due to this, a species of animals, plants, or insects slowly change some of their physical characteristics and adapt to nature.
According to the context of this question, it was the time of about 3.75 million years ago, when the transition between fish and first-legged animals was observed. This observation clearly demonstrates that the evolution of hind legs in the animals was actually initiated through the hind fins of the fish.
Therefore, the importance of Tiktaalik roseae to the study of evolution is understood by the fact of describing well-preserved pelves and a partial pelvic fin in aquatic organisms.

In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?
Answer:
The correct answer is - Bb and Bb.
Explanation:
In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:
BB and BB or Bb and Bb or Bb and BB
1. In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb
B b
B Bb Bb
b Bb bb
thus, the correct answer is - bb which is silver feather.

Answer:
C
Explanation:
If a sample of DNA is 21% adenine, it would be % cytosine.
Answer: 28%
Explanation:
Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio
21% Adenine and 21% Thymine
21% + 21% = 42 100 - 42 = 56 56 / 2 = 28
28% Cytosine and 28% Guanine

Answer:
B
Explanation:

A company wants to test a new dog food that
is suppose to help overweight dogs lose
weight. Fifty dogs are chosen to get the new
food, and 50 more continue their normal
diets. After one month, the dogs are
checked to see if they lost any weight.
What’s the Independent variable, dependent variable, experimental group, and and control group?
Answer:
- Independent Variable: the new dog food
- Dependent Variable: weight loss in dogs
- Experimental Group: dogs that eat the new food
- Control group: dogs that continue with their normal diets
Explanation:
In a scientific experiment, the dependent variable is the variable being tested/measured, while the independent variable isn't changed by the other variables that are being measured during the experimental procedure. Moreover, the experimental group is the group of individuals/subjects that is exposed to the independent variable, i.e., they are exposed to the experimental treatment. Finally, a control group is a group that exhibits the same characteristics as the experimental group but doesn't receive the experimental treatment, thereby enabling comparisons with the experimental group.

Most waves are created by ocean currents
Answer: yes
Most waves in the ocean are wind generated waves. Ocean surface currents are produced by major overall patterns of atmospheric circulation, the Coriolis Effect and the shape of each ocean basin. Ocean surface circulation brings warm equatorial waters towards the poles and cooler polar water towards the equator.
