Answer:
It is very possible for a plant to grow on mars, but you would need better soil, because mars' soil is filled with perchlorate salt which is toxic to plants. You would also need to conceal the plant, because the temperatures on mars are usually freezing. But yes, you could have a cactus on mars, it would just be very difficult to sustain.
Explanation:
Answer:
In response to what another user said, I would suggest bringing fertilized soil to Mars, placing it on the surface of the soil, and planting the cactus.

Define biodiversity and the importance of diversity in ecosystems. How could humans harm an ecosystem's biodiversity?
Answer:
Biological diversity - or biodiversity - is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans.
Explanation:
Biodiversity is important to humans for many reasons. ... Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. If no changes are made in the ways humans use resources on earth, there will continue to be a degradation of biodiversity until human lives can no longer be sustained. Humans affect biodiversity by their population numbers, use of land, and their lifestyles, causing damage to habitats for species.

Answer:
WELL UMMMMM.....
Explanation:
THERE ARE SOUND WAVES THAT TRAVEL THROUGH THE AIR AND YOUR EAR HEARS SOUNDS FROM THAT SO YAAA
Answer:
Sound waves travel through a medium(Solid, Liquid, and gas). So, the higher the frequency of a sound the more likely you are to hear it, also, we use our ears by listening to sound page. The ears detect sounds by listening
A student wants to use the Venn diagram below to show the characteristics of two kingdom of organisms. The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersed.
Which of these is a characteristic that the student should list in the shaded part of the diagram?
A. Heterotrophic
B.mobile
C.prokaryotic
D.multicellular
Answer:
Multicellular
Explanation:
I just took the test and got it correct.
The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersed are multicellular. Thus the correct option is D.
What is multicellular?Multicellular organisms is refer to as that composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Fungi can be single celled or very complex multicellular organisms. They are found in just about any habitat but most live on the land, mainly in plant or on soil rather than in fresh water or sea. Plants are multicellular autotrophs with cell walls made of cellulose, and they cannot move around.

Tall eyes - genotype
Short eyes - genotype
Tall eyes - phenotype
B. The hospital made a mistake because the combinations all have T in them, which is dominant. The combination has to have tt for the baby to have short eyes. But tt is not a possible combination in this situation. So it is not possible for the baby to have short eyes, however tall eyes are possible.

Artificial selection is based upon humans making the choice about which traits are favored and which parents will be allowed to reproduce. Natural selection is based upon factors in the natural environment favoring certain parents to produce offspring
Answer: True
Explanation:
The artificial selection allows humans to exploit the genetic resources (alleles, genes) of the organisms during mating. This allows the transmission of valuable and desirable traits of both parents to the offspring. This improves the quality of milk, meat, and plant yield. Natural selection is a natural phenomenon human have no role in natural selection. In this the nature selects those individuals to survive in their environment which have better phenotypic traits over others. These traits allows the organism to survive and reproduce and the beneficial traits are passed on to the next generation. On contrary, the traits which are beneficial in one kind of environment can be harmful in other environment. For example, the bears have thick coat which allows them to survive in cold conditions but in extreme heat they may not survive.
why are plants called nature's purifier?
☁️ Answer ☁️
Plants are called as natures air purifiers because they perform photosynthesis in which they take in carbon dioxide from the atmosphere and give out oxygen .
❤️
plants are a natural type of filter and can purify the air of harmful contaminants. It’s no wonder why the air purifier vs indoor plants debate is such a hot topic. Unfortunately, plants can’t absorb all forms of air pollution.
