What prevents a lake or ocean from freezing solid?
Answer:
The surface layer of the water freezes solid creating a barrier that insulates the ice below so that it keeps a steady temperature usually a few degrees above freezing (32 degrees).
Explanation:
List one organism and describe all of its adaptations.
Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.
What is adaptation?
In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.
Adaptation involves molecular, physiological, morphological, and behavioral changes.
For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.
A good and easy to unsderstand example of adaptation is the cactus.
Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.
To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.
They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.As their leaves are not developed, their stems photosynthetize to produce organic compounds.
Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.
To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

Why is the water cycle important for ecosystems?(1 point) The water cycle helps recycle and transport carbon around the planet. The cycle replenishes the carbon supply of ecosystems. The water cycle uses photosynthesis to make clouds. These clouds make surface water that animals drink to survive in their ecosystem. The water cycle permanently removes water from underground and large bodies of water and transports it to terrestrial ecosystems that need water. The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Answer: The water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems
Explanation:
The water cycle simply refers to how water continuously move within the Earth. It is also called the hydrological circle. Water cycle depicts many processes such as how water evaorates into vapor, how clouds are formed through condensation and then sent back to the Earth as either rain or snow.
Based on the options given, the water cycle helps recycle and transport water around the planet. The cycle replenishes the water supply of ecosystems.

1. How do radiation, conduction, and convection affect the atmosphere?
2. How does greenhouse effect warm the earth?
Answer:
1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.

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.

The genetic information is identical to the parents.
b
The offspring are made of cells.
c
The genetic information comes from the parents but is not identical.
d
The offspring inherit traits from the parents.
Answer:
c
Explanation:
Only in asexual reproduction the genetic information is identical. Sexual produces genetics that are combination of both parents, producing non-identical offspring.

What is the full form of DNA ?DNA stands for deoxyribonucleic acid.
DNA contains the orders that are needed for any organism in order to develop, survive as well as reproduce. To carry out these duties, DNA sequences are needed to be converted into messages which can be used to produce proteins in which are the complex molecules that are doing most of work in our body.
Since we have two pairs of chromosomes and we also have two pairs of genes in which one is from our father and one is from mother. These pairs of genes then determine certain physical features or traits.
