I belive that the elements 1 through 92 occur naturally on Earth, except for elements 43 and 61, although these are only found in very limited concentrations. The elements mostly on the periodic table that accompany uranium are generated only chemically and are classified as transuranium or transuranic components.

Which of the following best describes a benefit of studying biology.
a. One is able to experiment on a variety of animals.
b. One is able to intelligently debate issues such as cloning.
c. One is able to preserve the animals that are extinct.
d. One is able to understand the causes of changes in weather.
Answer:
The statement that best describes the benefit of studying biology is the ability to intelligently debate issues such as cloning.
Explanation:
Biology encompasses the study of all known forms of life, including their anatomy, organization, functioning and interactions.
One of the advantages of the knowledge acquired through biology is to be able to participate in works and discussions involving subjects related to living beings, including cloning.
The other options are not correct because:
a and c. The ability to experiment on animals or preserve animals that are extinct is reserved for scientists with a deep knowledge of biology and its fields.
d. Understanding the causes of wheather change does not correspond to knowledge in biology
Why the tropical forest has a more lush plant life than the tundra in regards to how fast things decompose.
Answer:
Because of Nitrogen
Explanation:
Nitrogen seems to be much difficult for plants to acquire because they can only consume nitrogen when it is combined with oxygen or hydrogen, which is why tropical forests have a lusher plant growth than tundra.The decomposition process is the secret to maintaining the nitrogen cycle going since the bulk of fixed nitrogen arrives from decaying organisms and faces being broken down by bacteria.answer please. i will mark brainliest

State the relationship between particle size and porosity
helppp
Answer:
The shape and size of the particles affect the way that they pack together in a certain amount of space, which affects a rock's porosity. ... But rocks change over time. When enough pressure, or force, is put on a rock, the pressure can make the rock pack its particles closer together.
Explanation:
I looked it up on google.
Answer:
the larger the particles the harder it is to pack the atoms together, however with the help from exterior forces they can be forced together.

Raul wants to study how pot size affects the growth of plants. To do this, he intends to purchase three different pots of varying diameter. Then, he will fill each pot with the same amount of soil and plant different kinds of flowers in each pot. Finally, he will place the pots side by side in a sunny location and water each pot daily with the same amount of water.
Answer:
No
Explanation:
Based on the exact methodology that Raul is using he will never produce valid results. This is mainly due to the fact that there are too many changing variables in his experiment. In order to produce valid results, the experiment can only have one changing variable (independent variable) at a time, while all of the other variables need to be controlled/constant. This would allow Raul to isolate which change is actually causing the desired effect in the plants. The way that Raul has his experiment set-up he will not be able to pinpoint exactly what variable or aspect is actually causing the growth of the plants.
How can an abiotic factor like temperature impact the population size of an ecosystem
Answer/Explanation:
Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.
They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.
If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.
Crossing over occurs when (4 points)
Answer:
Crossing over is the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis, which results in new allelic combinations in the daughter cells.
When chromosomal homologs communicate with one another during Meiosis I's metaphase, crossing over takes place.
What is Crossing over?When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.
Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up. The same genes may be present on the two chromosomes in different versions.
The exchange of genetic material between non-sister chromatids of homologous chromosomes occurs during crossing over, an enzyme-mediated process. It happens during meiotic prophase I's pachytene stage.
Crossing over occurs during Meiosis I's metaphase when chromosomal homologs interact with one another.
Thus, this way, crossing over takes place during meiosis.

Answer:
Synthesis
Explanation:
interphase-cell appeared to be at synthesis phase.
What happens in the synthesis phase?S phase is the phase of the cell cycle in which DNA is replicated, occurring between G₁ phase and G₂ phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase.
S phase (Synthesis Phase) is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division.
S phase, or synthesis, is the phase of the cell cycle when DNA packaged into chromosomes is replicated. This event is an essential aspect of the cell cycle because replication allows for each cell created by cell division to have the same genetic make-up.
