Answer:
When an organism makes more of itself without the exchang of genetic information with another organism through sex, the reproduction is asexual.while
In sexual reproduction, the exchange of dna and other genetic material is required as it involves two separate organisms.Finally
Asexual is better in terms of time, less energy and only one organism (the parent cell) is needed for the process.Besides plants and insects, what else would the student need in the ecosystem? Why?
Random mutations can occur in an organism's DNA, causing traits that are different from other organisms in that species. Sometimes these mutations can cause problems for the organism, but other times they are beneficial. What is a possible benefit to a random mutation in an organism?
Answer: It can increase an organism’s chances of surviving

A student wants to know what effect temperature will have on the germination rate of radish seeds. To test this, she obtains 3 petri dishes and 60 radish seeds. She places 20 seeds in the first petri dish and stores it at room temperature. She places another 20 seeds in the second dish and places it in the freezer. She places 20 seeds in the third petri dish and places the dish in an incubator. Over the next two weeks, she waters the dishes daily and records the number of seeds germinate. At the end of the experiment she calculates the germination rate for the seeds at each temperature.
Hypothesis: ____________________________
Experimental Group: ____________________________
Control Group: ____________________________
Manipulated Variable (IV): ____________________________
Responding Variable (DV): ____________________________
Constants: ____________________________
Answer:
Hypothesis: IF the temperature is high, THEN the germination rate of radish seeds will increase.
Experimental Group: 20 Seeds in petri-dishes placed in the freezer and incubator each
Control Group: 20 seeds stored at room temperature
Manipulated Variable (IV): TEMPERATURE
Responding Variable (DV): GERMINATION RATE
Constants: Amount of water, same amount of time (2 weeks)
Explanation:
- The hypothesis is a testable explanation given to an observed problem. A possible hypothesis is IF the temperature is high, THEN the germination rate of radish seeds will increase.
- Independent or manipulated variable is the variable that is changed or manipulated variable in an experiment. The TEMPERATURE is the independent variable in this case.
- Dependent or responding variable is the variable that is measured in an experiment. In this case, the dependent variable is the GERMINATION RATE
- The experimental group is the group that receives the experimental treatment. In this case, the experimental group is the 20 Seeds in petri-dishes placed in the freezer and incubator each.
- The control group is the group that does not receive the experimental group. In this case, the control group is the 20 seeds stored or placed at room temperature.
- Constants are the variables that are kept unchanged throughout the experiment. In this case, the constants are Amount of water, same amount of time (2 weeks)

. Write the differences between:
a. Root cap and root hairs
b. Tap root and fibrous root
C. Vegetative parts and reproductive parts
d. Terminal and axillary bud
e. Reticulate and parallel venation
f. Alternate and whorled arrangement of leaves
Explanation:
fibrous root system occupies less surface area than taproot . taproot grows vertically downwards and thus reaches deep into the soil. the fibrous roots grow horizontally in all directions and thus richest deep in the soil
Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. (PLEASE HURRY!)
Isotopes have different mass numbers due to different number of neutrons but same atomic number due to same number of electrons and protons.
What are isotopes?
Isotopes are defined as substances having same number of protons but different number of neutrons.Number of protons is characteristic for determining position of elements in the periodic table.
Since,all isotopes have the same number of protons and hence have same position.They have similar chemical properties as they have same number of electrons.
They find applications in the field of nuclear medicine and oil and gas research . There are 2 types of isotopes : stable and unstable
Unstable isotopes are radioactive and are called as radioisotopes.Some of these isotopes are man -made and hence also called as artificial isotopes.Every element has an isotope which is either man-made or natural .
Many properties of isotopes depend on mass which is measured in atomic mass unit. The difference in actual mass and mass number is called mass defect.

scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have --
A. flagella
B. hereditary material
C. Cell walls
D. Nuclear Membranes
Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.
What are the difference between eukaryotes and prokaryotes?Eukaryotes are distinguished from prokaryotes in that they organelles enclosed within a nuclear membrane. The organisms of spinoloricus are radically different from other known eukaryones in that they lack mitochondria and are able to exist in the absence of oxygen. However, their genetic material is contained within a nuclear membrane and they are therefore eukaryotes rather than prokaryotes.
Taking into consideration the main characteristic of each group, prokaryote, and eukaryote. In the first case, we have that it laks nucleus and has no sexual reproduction, meanwhile, the eukaryote has organelles and has sexual reproduction. Taking this into account we can proceed to answer each part.
Therefore, Scientists determined that organisms of the genus spinoloricus we eukaryotes and not prokaryotes because spinoloricus cells have cell walls. Thus, option C is correct.

Answer:
Glucose passes through a series of catabolic reactions in the process of cellular respiration. First, glucose is split in the cytoplasm in the process of glycolysis. The resulting end-productsmove into the mitochondria and go through a preparatory step to the Krebs cycle, and finally to the electron transport system.

Geological Oceanography
Physical Oceanography
Chemical Oceanography
Biological Oceanography
Answer: Oceanography is the study of all aspects of the ocean. Oceanography covers a wide range of topics, from marine life and ecosystems to currents and waves, the movement of sediments, and seafloor geology Geological oceanography is the study of Earth beneath the oceans.
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.
Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.
Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.
