Which series of labels correctly identifies the indicated structures in this sketch of a cell viewed under a microscope?
juin [17]

Explanation:

B [A.Golgi apparatus B.nucleolus C.endoplasmic reticulum D.mitochondrion E.ribosome F.lysosome]

Cellular organelles comprise proteins parceled into  membranes. These allow for storage of substances, and specialization of cell function.

Further Explanation:

Cells' structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates.

In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

  • may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes such as the mitochondria
  • separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins as seen in lysosomes
  • More specifically some organelles like vacuoles play a structural role in the cell; supports the cell membrane by exerting turgor pressure.

Other structures also play important support roles:

  • Nucleus:  houses all the genetic information of the organism
  • most proteins that function in the cytosol nucleus (such as DNA polymerase) are synthesized by free ribosomes.
  • Cytoplasm: contains the cytosol, microfilaments and other support structures in the cytoskeleton; it holds parts of the cell together
  • Golgi apparatus: protein modification and parceling for export

How does sand silt and Clay affect soil nutrients and plants
Ghella [55]
Sand is granular and coarse meaning that water and nutrients can flow through it quite easily. Clay on the other hand has very fine particles that cling together to form a waterproof substance which traps/ stops any nutrients or water from moving down. Clay's also quite difficult for plants to get their roots into. Silt has a texture between clay and sand, meaning that it is the ideal substance as it allows the best water and nutrition movement in the soil. Most plants will grow best in silt, but there are some plants who are more adapted to living in sand (e.g. Marram grass) or clay.

Which statement about the effects of natural events and human activities is true?
andreyandreev [35.5K]

Answer:

B. Human activities and natural events can damage the environment.,

Explanation:

Human activities are those activities carried out by a human being. The environment is being degraded daily as a result of the activities of man as well as natural occurrences e.g earthquake, tsunami, wild fire etc.

Human activities also called anthropogenic activities that damage the environment include sewage pollution, burning of fossil fuels, oil spillage etc. Hence, according to this question, human activities and natural events can damage the environment.

What is the relationship between dna replication and the s phase of the cell cycle?
Alina [70]
 DNA synthesis occurs during the S phase, between the G1 and G2 phases of interphase. DNA replication is therefore complete before the mitotic phase begins.
