Answer:
Recessive
Explanation:
All of the offsrping were black so that means black was the dominant gene and white was the recessive
At the time when the pure black hamsters were mated so here, the whiteness trait should be called the recessive.
What is recessive?It refers to the allele type that should not be manifested in an individual till both individual copies of the gene should include the particular genotype.
And, all the offspring should be considered as black so here black treated as the dominant gene and white should be considered as the recessive
Hence, the whiteness trait should be called recessive.

Which of these best fits the empty cell in Nicole's model?
warm, moist air rises
warm, dry air descends
water vapor condenses in clouds
water vapor evaporates from ocean
Answer:
The correct answer is - warms, moist air rises.
Explanation:
When moist warm air rises and meets with the surface of cool air the more dense air that is cold air end up below the warm moist air in the troposphere it condenses as it rises.
The condensation of the warm, moist water leads to the formation of cloud formation. This cloud gets bigger and bigger until it precipitates and rain fall occurs.

Two insect groups vary genetically by two genes. When put together, they were able to reproduce and produce offspring that could also breed. Which best describes this insect population?
The insects experienced geographic isolation.
The insects experienced reproductive isolation.
The insects are different species.
The insects are the same species.
The answer is D. The insects are the same species.
The insects are the same species best describes this insect population.
What is reproductive isolation?The fact that the two insect groups were able to reproduce and produce offspring that could also breed indicates that they are not experiencing reproductive isolation. Reproductive isolation occurs when two populations of organisms can no longer interbreed due to genetic or behavioral differences.
Since the two insect groups can interbreed and produce viable offspring, it suggests that they are not different enough genetically to be considered different species.

Question 5 (5 points) (04.03 MC) A student made the following diagram to represent cellular respiration. Why is this diagram incorrect?
A.water is not used up during this process.
B.glucose is not used up during this process.
C. The arrow for oxygen should point in the opposite direction.
D. the arrow for carbon dioxide should point in the opposite direction.
Answer:
A
Explanation:
The chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O (+ ATP)OR: Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)
Since water is on the right side of this equation, it is produced as a result of the metabolic process rather than used up. So, the correct is A.

Darwin explained that all life came from ________________
Question 3 options:
one bacteria
one adaptation
The 4 kingdoms of living things
one common ancestor
Answer:
one common ancestor
Explanation:
Although Darwin’s theory is often described as the theory of evolution by natural selection, most commentators recognize that common ancestry (the idea that all organisms now alive on earth and all present day fossils trace back to one or a few “original progenitors”) is an important part of the Darwinian picture.
Answer:
Darwin explained that all life came from one common ancestor.

Will give Brainliest within five minutes of answer - Why do we want to explore Mars more than the other planets/moons even though it is not currently habitable (with its temperatures, atmosphere, etc.)? How can it be habitable?
Answer:
After the Earth, Mars is the most habitable planet in our solar system due to several reasons:
Its soil contains water to extract
It isn’t too cold or too hot
There is enough sunlight to use solar panels
Gravity on Mars is 38% that of our Earth's, which is believed by many to be sufficient for the human body to adapt to
It has an atmosphere (albeit a thin one) that offers protection from cosmic and the Sun's radiation
The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds
The only other two celestial bodies in orbits near the Earth are our Moon and Venus. There are far fewer vital resources on the Moon, and a Moon day takes a month. It also does not have an atmosphere to form a barrier against radiation. Venus is a veritable purgatory. The average temperature is over 400 degrees, the barometric pressure is that of 900 meters underwater on Earth, and the cherry on top comes in the form of occasional bouts of acid rain. It also has nights that last for 120 days. Humans cannot live on Mars without the help of technology, but compared to Venus it's paradise!
Additional info:
Mars is an obvious target for exploration because it is close by in our Solar System, but there are many more reasons to explore the Red Planet. The scientific reasons for going to Mars can be summarised by the search for life, understanding the surface and the planet’s evolution, and preparing for future human exploration.
Searching for life on Mars
Understanding whether life existed elsewhere in the Universe beyond Earth is a fundamental question of humankind. Mars is an excellent place to investigate this question because it is the most similar planet to Earth in the Solar System. Evidence suggests that Mars was once full of water, warmer and had a thicker atmosphere, offering a potentially habitable environment.

Answer:
.Variation within a population is heritable. Populations experience competition for resources.
Explanation:
Variation exist among individual, and this makes individual unique. Variation in shape,size,color exist in an organism.
Traits or character can be inherited from parents which means it can be transfer from one person or individual to another.
Each organism posses different traits for survival, some traits are presents as to better help some organism adapt to their environment.

Why do we use specific terminology when referring to the gender and species of common domestic animals?
Answer:
To know which exact organism you are referring to, and there is no confusion about it.
Explanation:
To identify organisms, we usually use two names. The common name and the scientific one.
Scientific name: binomial nomenclature.
The scientific name designates a species through binomial nomenclature. The binomial nomenclature is a standard agreement used to identify different organisms. It has international validity, and it does not change among regions or languages. One binomial name is used only on one organism and can not repeat. It is composed of two Latin words: gender and the specific name. Many species might share the same gender for being very similar, so the specific name is used to identify each species.
Common names:
These are informal names, determined by the people of a region or area, that speak the same language. They are regional names, so they change from region to region, even when referring to the same organism. Usually, these names designate only organisms that have importance for the people. The same name might refer to different organisms, and in many cases, the same organism might receive many names. For this reason, there might be confusion when using only common names to talk about a species.
If we need to refer to a particular organism, we should always use the scientific name to avoid confusion. As it is internationally recognized and accepted, anybody can know which species you are talking about, independently of the region or the language. In most cases, people mention a species using the scientific name together with many of its common names.
Why is adequate lighting necessary in a balanced aquarium?
a. Fish need light to see their food.
b. Fish take in oxygen in the dark.
c. Plants expel carbon dioxide in the dark
d. Plants grow too rapidly in the dark.
Answer:
A. Fish need light to see their food
Explanation:
B is incorrect because fish take in oxygen constantly to respirate. If they only took in oxygen when it was dark they would die.
C is incorrect because expelling CO2 is also a constant process as a part of the reactions that take part inside living organisms, so it happens constantly (a bit like B)
D is incorrect because plants need light for food (photosynthesis) and would most likely die or have stunted growth if left in the dark.
A is correct because when it is dark, fish rely on other senses to find food as most fish cannot see as well in the dark, therefore when they have light they can see their food more easily.

Three common methods employed in the cleanup of oil spills are aeration of water, skimmer boats, and genetically engineered bacteria aeration of water, skimmer boats, and genetically engineered bacteria A aeration of water, phytoremediation, and genetically engineered bacteria aeration of water, phytoremediation, and genetically engineered bacteria B skimmer boats, high temperature incineration, and phytoremediation skimmer boats, high temperature incineration, and phytoremediation C large floating booms, high temperature incineration, and phytoremediation large floating booms, high temperature incineration, and phytoremediation D large floating booms, skimmer boats, and genetically engineered bacteria
Answer:
large floating booms, skimmer boats, and genetically engineered bacteria
Explanation:
Skimmers are used in the clean up of oil spills it makes use of containment skims that act like a fence and the surface of water and prevent the oil spill from moving or spreading across the water surface. It contains the oil into a particular place. Floating booms helps in the sucking out of oil in the confined area, its act like a vacuum pump and suck out all the oil spills available in the areas confined by the skimmers.
Bioremediation involves the use of microorganisms to clean up spills this micro organism breaks down this petroleum product into harmless substance through their metabolic activities. Genetically modified Bacterial can be use for this purpose to help break down this hydrocarbons and make them less toxic.
