What significance does density have for earth?
Answer:
The atmosphere and Earth's interior are layered by density. Gravity pulls more strongly on denser materials so denser materials are at the center of things. Earth's core, at its center, is denser than its crust. The lowest layer of the atmosphere is denser than the upper layer.
factors affecting environment and development
Answer:
Environmental factors affecting plant growth and development include light, temperature, water, humidity, and nutrition. At the time of nurturing a tree, it is important to know how these factors could affect the growth and development of a plant. Knowledge about environmental factors helps the owner promotes proper growth.

Which of mendels generations was allowed to self pollinate
Mendel allowed the F1 generation plants to self-pollinate
Why Mendel allowed the F1 generation plants to self-pollinate?The parent plants in the tests carried by Mendel have recognized as the P (for parent) contemporaries.
The F1 stands for the first filial generation, which was taken on cross-pollinating the parent plants. The F2 holds for the second generation, which is accomplished after self-pollinating the F1 breeding plants.
Thus, Mendel allowed the F1 generation plants to self-pollinate

Option B is your answer choice. Have a great day ☺
On the effects of similarity on attraction, the following is most likely to be William's reaction, William will be more attracted to Kate than he would a stranger. Thus, option "B" is correct.
How they both share many of the same beliefs and interests?Research has found people tend to feel attracted to those who are similar to them, which is probably an evolved preference.
Still, there are several explanations for this liking. Psychologist says we believe people who are similar to us will be more likely to like us. Another reason would be that shared experiences and values make us feel more certain and positive in the world. Whatever reason it may be, the truth it psychology sees such tendency as deeply rooted in the human psyche.

Given the strand of DNA with the sequence : G-A-C-A-T-T-C-C-G...
Column A
Column B
1.
What is its complementary strand?
a. C-T-G-T-A-A-G-G-C
2.
b. G-A-C-G-A-T-T-C-C-G
Which sequence represents and insertion /

3.
C. G-A-C-T-A-T-C-C-G
4.
d. G-A-C-A-T-C-C-G
Which sequence represents an inversion
mutation?
Answer:
1. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the complementary sequence is C-T-G-T-A-A-G-G-C (a).
2. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the insertion sequence is G-A-C-G-A-T-T-C-C-G (b).
3. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the deletion sequence is G-A-C-A-T-C-C-G (d).
4. Given the DNA sequence: G-A-C-A-T-T-C-C-G, the inversion sequence is G-A-C-T-A-T-C-C-G (c).
Explanation:
The complementary sequence of DNA is a sequence of complementary nucleotides. The complement is a nitrogenous base that correctly pairs with the base that is given. In DNA, Adenine (A) correctly pairs with Thymine (T), and Guanine (G) with Cytosine (C). Therefore, the complement of A is T, and of C, is G.
The given sequence complement would be C-T-G-T-A-A-G-G-C since it's a sequence of bases that correctly pairs with the given sequence, G-A-C-A-T-T-C-C-G. [ G-A-C-A-T-T-C-C-G | C-T-G-T-A-A-G-G-C ] Notice that the first base in the sequences is G and C respectively. The next two are A and T. The paring is such that C complements G, and that A, T.
2. An insertion sequence is one in which there is an extra added nucleotide or codon. [ G-A-C-A-T-T-C-C-G ] Notice that there are three Triplets in this sequence. In a case where there is an extra nucleotide(s) or codon(s), such is termed an insertion mutation. When the given sequence is compared with the sequence in option b, G-A-C-G-A-T-T-C-C-G, you can observe an extra nucleotide [G - the fourth letter in the sequence]. Therefore, this sequence is called an insertion sequence.
3. Deletion mutation is an error in the DNA replication process that removes a nucleotide(s) from the genome. Hence a sequence that has a nucleotide(s) removed from the original sequence is called a deletion sequence. With the given sequence, G-A-C-A-T-T-C-C-G, the deletion sequence to this is G-A-C-A-T-C-C-G. [G-A-C-A-T-C-C-G ] Notice that one of the nucleotides, T, is missing.
4. Inversion mutation is a chromosome rearrangement in which a chromosome is reversed end to end. This involves breaking and rearrangement within a sequence. With the given sequence, G-A-C-A-T-T-C-C-G, an inverted sequence is G-A-C-T-A-T-C-C-G. [ G-A-C-T-A-T-C-C-G] Notice the first two nucleotides, of the second codon (....-T-A-T-...). The original sequence has....-A-T-T-...., but the new sequence here has...-T-A-T-.... Suggesting that the first two nucleotides were broken and rearranged end to end.

Answer: 1. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?

What is the general relationship between distance from the sun and a planets density?
Answer:
There is no connection between a planet's distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period). While it is true that, generally speaking, the gas giants have higher rotation rates than the earth like planets closer to the Sun, any correlation is only coincidental.

During a hectic moment in the ER, Robin received a needle stick from a hyperdermic used on the patient. She later was diagnosed with Hepatitis B. This would be an example of what type of transmission?
Answer:
Fomite Transmission
Explanation:
The type of transmission used as an example in this scenario would be Fomite Transmission. This is when an inanimate object that has been in contact with a disease becomes contaminated and then comes into contact with an individual. In this scenario, once the needle was used on the patient that had Hepatitis B it immediately became contaminated. Then by accidentally being stuck by the needle, Robin became infected as well as the disease was transmitted from the needle into her bloodstream.
