Cell membrane is the answer
The fossil symbols and mountain belts were helpful because it showed where the land and water dinosaurs were able to live, especially with the non-swimmers in Africa and South America. There is proof of some mountains matching in Western Europe and Greenland.
Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
Answer:
i. Maize seed is a monocot seed whereas bean seeds are dicot seed.
(ii) Maize seed only have a single leaf inside, most of the space inside the seed is reserved for endosperm but bean seed have two leaves, both of which store and provide food to the seedling in absence of endosperm.
(iii) Corn seeds (maize) germinates in three days but bean seed takes seven days to germinate.
Explanation:
Die is two, mono is one
Answer:
The alleles for MADS-box genes get expressed at different levels. They form the “L” complex and the “SP” complex. These are a group of proteins that determine the shape of the petals. The more they L complex is expressed, the high the probability that the petals of the flower will form the ‘lip’ and the high the SP complex is expressed then the high the likelihood of dominant petals.
