Answer:
some molecules pass
Explanation:
The ability of a membrane to pass or not to pass a substance is its permeability (permeability).
Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.
The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.
Answer:
d
Explanation:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
It differs from DNA chemically in two respects: (1) the nucleotides in RNAare ribonucleotides—that is, they contain the sugar ribose (hence the name ribonucleic acid) rather than deoxyribose; (2) although, like DNA,RNA contains the bases adenine (A), guanine (G), and cytosine (C), it contains the base uracil (U) .
Ans.
The phloem is living plant tissue ,found in vascular plants and made up of parenchyma cells and sieve elements. Phloem performs translocation, which involves transport the soluble organic products of photosynthesis, mainly the sucrose from photosynthetic sites other plant parts where needed.
Thus, the primary function of the phloem in vascular plants is to perform 'translocation.'
The geochemical cycle that is least likely to be affected by global warming is the water cycle, because even as temperatures increase, the evaporation cycle will remain the same.
<h3>How to describe the water cycle?</h3>
- at the beginning — liquid: water is present in the transpiration of living beings, in addition to rivers, lakes, oceans, etc.
- in the middle — gaseous: this water evaporates and accumulates, to later condense in the clouds
- at the end — liquid: the precipitation of water that returns to Earth in the form of rain occurs, restarting the cycle.
With this information, we can conclude that the water cycle, also known as the hydrological cycle, refers to the continuous movement that water makes through the physical environment and the living beings of the ecosystem, passing through the atmosphere, hydrosphere, lithosphere and biosphere.
