Answers
Answer:
[tex] H_2SO_4 [/tex]
Explanation:
In the first option, the compound [tex] HClO_3 [/tex] has 1 hydrogen atom and 3 Oxygen atoms. There are 3 times as many oxygen atoms as hydrogen atoms.
In the second option, the compound [tex] H_2SO_4 [/tex] has 2 hydrogen atom and 4 Oxygen atoms. That is 2:4 = 1:2. Therefore, there are twice as many oxygen atoms as hydrogen atoms.
In the third option, the compound [tex] H_2O [/tex] has 2 hydrogen atoms and 1 Oxygen atom. There are ½ times as many oxygen atoms as hydrogen atoms.
In the fourth option, the compound [tex] H_3PO_4 [/tex] has 3 hydrogen atoms and 4 Oxygen atoms. 4 oxygen atoms to 3 hydrogen atoms.

In terrestrial ecosystems, some nitrogen-fixing bacteria in soil and root nodules also convert nitrogen gas directly into ammonium ions. ... Other nitrifying bacteria convert the nitrites to nitrates, which plants can absorb. The process of converting ammonium ions to nitrites or nitrates is called nitrification.

Certain bacteria change nitrogen gas into a usable form in a process called nitrogen fixation.
What is nitrogen fixation?Nitrogen fixation process is important for the growth of plants, as nitrogen is an essential component of many plant nutrients. Nitrogen fixation is primarily carried out by bacteria in the genus Rhizobia, which form symbiotic relationships with certain plants, such as legumes. The bacteria live in nodules on the roots of these plants and convert atmospheric nitrogen into a form that can be used by the plant.
This process is also important for the overall health of the soil, as it helps to increase the availability of nitrogen for other organisms in the ecosystem.

eukaryotes
Answers
Answer:
eukaryotes
Explanation:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Eukaryotic cell have membrane bound organelles. Thus, the correct option is eukaryotic cell.
What is eukaryotic cell?The eukaryotic cell is known as the fully developed and it contain membrane bound organelle. The multicellular organism are made up of the eukaryotic cell and they contain cell organelle it contain mitochondria, ribosomes, RNA, DNA, golgi appratus, and nucleus as well as other cell organelles.
Multicellular organisms are made up of eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.
Amoeba has known as an unicellular organism in which all the activities related to life carried out in a single cell. The example of multicellular organism is human beings and other animals as well plants are also came in the category of multicellular.

Answer:
Letter B is on the steepest slope.
Explanation:
A is not correct because letter A is on a position where the contour lines are not close to each other, suggesting that the slope is not mild.
B is correct because the spacing between the contour lines where the letter B is marked is very small, suggesting that the slope is very steep.
wC is not correct because just like with letter A, the contour lines are not close to each other, but are further away, suggesting that the slope is not steep but it is mild.

Which of these is a distinguishing characteristic between the domains Bacteria and Archaea?
Answers
Answer:
This question lacks options, the options are:
a. Their size
b. The chemical composition of the cell wall and cell membrane
c. Their ability to grow at high temperatures
d. The shape of their mitochondria
The answer is B
Explanation:
Living organisms has been classified into three domains namely; Eukarya, Archaea, and Bacteria. However, domians Archaea and Bacteria are most similar in the sense that they both have cells without a membrane-bound nucleus, hence, they are both PROKARYOTIC. Also, they are both strictly unicellular organisms.
Despite these similarities, differences exists between them. One major difference is in the chemical composition of the cell wall and cell membrane. The cell walls of bacteria cells have a unique structure called PEPTIDOGLYCAN. This is absent in the Archeae group. Also, the cell membrane of Archeae is made up of ether linked lipids compared to the ester-linked lipids that constitutes bacteria cell

Explain how soil formation is helped by biotic components through primary succession.
Answers
Answer:
Please find the explanation below
Explanation:
Primary succession is a type of succession that occurs in an area with no previous community. It usually contains bare rocks, which are grown upon by certain living organisms (biotic components) called PIONEER SPECIES. These organisms, which include lichens and mosses, colonize the bare rocks and contribute to the formation of soil by the gradual disintegration of the rock particles.
These biotic components (living organism) also help to enrich the soil being formed as they add organic matter, which serve as nutrients, when they die and decompose. The actions of these living organisms on the formation of soil enables other organisms to easily colonize the area.

14. What is the meaning of Agri-
Answers
Li-Fraumeni syndrome (LFS1) is a rare hereditary disorder that leads to a predisposition to cancer. This hereditary disorder is linked to mutations in the tumor suppressor gene encoding the transcription factor p53. p53 acts at the G1 checkpoint. If damaged DNA is detected, p53 halts the cell cycle. As p53 levels rise, the production of p21 is triggered. p21 enforces the halt in the cell cycle. A variant of Li-Fraumeni, called LFS2, is thought to occur due to a mutation of the CHK2 gene, which is also a tumor suppressor gene. CHK2 regulates the action of p53. Which of the following cascades is most likely to occur in a normal cell that does not contain the LFS mutation?
Answers
Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.
