Answer:
It's Oxygen.
Explanation:
Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air.

Which type of isolation is being described: Yellow butterflies breed during the summer season while red butterflies breed during the winter season, because of this, they cannot interbreed
temporal isolation
geographic isolation
behavioral isolation
By stating that "Yellow butterflies breed during the summer season while red butterflies breed during the winter season" we are referencing a form of temporal isolation.
Temporal isolation is one of the limiting factors for sexual reproduction between closely related species. Temporal isolation refers to the situation in which two closely related species cannot interact sexually with one another due to the timing of their respective mating events.
The question states that the yellow butterflies will breed during the summer season, whilst the red butterflies breed during the winter. Normally, species like this are closely related enough to allow interspecies breeding to take place and create a new species or simply diversify the existing ones. However, due to the distinct timing of the breeding cycles for each butterfly, they will not be able to breed with one another, which is a prime example of temporal isolation.

What happens during meiosis I? *
a. Chromosomes line up in pairs, separate, forming haploid cells
b. Chromosomes line up in pairs, separate, forming diploid cells
c. Chromosomes line up single file, separate, forming haploid cells
d. Chromosomes line up single file, separate, forming diploid cells
Answer:
What is c. Chromosomes line up single file, separate, forming haploid cells
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

how plating trees can be a problem
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
There are even more serious issues, as trees have several ways of influencing the climate. The first problem is that trees are dark in comparison to other things that could cover the ground, such as grass or snow. Planting more trees, as a result, tends to make the terrain darker.
Tree planting on a large scale is becoming a more popular part of worldwide efforts to fulfil climate objectives. Forests, on the other hand, are complex ecosystems, and haphazard planting can actually raise carbon dioxide (CO2) levels in the atmosphere, contributing to global warming.

5 organelle cells not found in human cells
Hurry homework due in couple minutes
Answer:
Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.
This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.
Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

Q5. Arrange the sources of fresh water according to decreasing percentage distribution. Q6. Which among the sources of freshwater can be easily tapped for human use? Q7. Make a short reflection on the availability of freshwater to human use. Will there be enough water in the future?
Surface water (rivers and lakes) are the most available source of fresh water. The other sources of fresh water are largely unavailable.
Water on earth could be fresh water or salt water. The difference between the two is that freshwater is not salty. There is a limited quantity of available freshwater on earth.
Fresh water is found in glaciers, surface lakes and rivers and groundwater.The order of decreasing availability of fresh water on earth is ice> Groundwater > lakes and rivers (surface water).
Unfortunately, the source of freshwater that can easily be obtained for human use is surface water (lakes and rivers). There is only about [tex]1\frac{2}{3}[/tex]% available freshwater in rivers and lakes. About 87% of the world's fresh water supply is locked away in glaciers.
Given the limited availability of fresh water sources, the possibility of an water challenges in the world can not be over emphasized. Definitely, there may not be enough water in the future hence water conservation efforts must be taken seriously.

Answer:

Explanation:
Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer
Answer:
A - Gain or Lose
Explanation:
Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.
During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.
The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.
For covalent bonding atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals
Answer:
Explanation:A: gain or lose
