I believe that both flatworms and roundworms have a body type called Bilateral symmetry. Animals that are bilaterally symmetric have mirror symmetry in the sagittal plane, which divides the body vertically into left and right halves, with one of each sense organ and limb pair on either side.
Answer:
Minerals can form in all geological environments, which allows them to have a wide range of chemical and physical conditions. Two forms of this are temperature and pressure. There are 4 main categories of mineral formations. Igneous is where the minerals crystalize from a melt. Sedimentary is where the raw materials of the mineral are particles from other rocks that have suffered from erosion and weathering. Metamorphic is where new minerals are created from earlier ones owing to the effects of change. Most of the time it's from increasing temperature and/or pressure. Hydrothermal is where the minerals are chemically precipitated from hot solutions in the earth.
Answer:
All of the following help the cell regulate gene expression during Step 2 of protein formation EXCEPT
specialty factors binding to the RNA polymerase, altering its specificity
Explanation:
Answer:
Ecosystem
Explanation:
An ecosystem is a level of organization referring to the group of living organisms including plants, animals, microbes interacting with one another, and also with the non-living parts of their environment e.g temperature, water.
Based on this explanation, a level of organization that encompasses all th living and non living factors interacting in the pond environment represent an ECOSYSTEM.
Answer:
It is because the axons that fail to find a target cell die thats why every axon in an adult mammal has a target cell (muscle cell or other neuron) with which it makes synaptic contact.
Explanation:
Synapse is basically a structure in the nervous system responsible for the passage of the electrical and the chemical signals from one neuron to another neuron or an effector cell.
Usually the axon is the presynaptic part of the synapse and the postsynaptic part is usually present on the body of the neuron or a dendrite or an effector cell like a muscle cell.
If the axon doesn't make a synaptic contact with the target cell , the axon will die because the neurotransmitters and the chemical mediators will not be released and no action will result on the postsynaptic membrane.
