How is a light element like helium is formed in stars and how is a heavier element like gold formed by stars? YALL HELP ME WITH THIS PLEASE
1. Elements are not formed in stars. All elements were formed during the Big Bang and no elements have been formed since then.
2. Both light and heavy elements are formed only under very high energy conditions, such as a supernova.
3. Only light elements like helium are formed by stars. They are formed from the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold cannot be formed under any condition.
4. A light element like helium is formed by the fusion of hydrogen nuclei. A hydrogen nucleus is made of a single proton. When protons fuse together, a new atom of helium is formed. Heavier elements like gold form under very high energy conditions, such as a supernova, when helium atoms combine under enough successive collisions to form very heavy elements.
Answer:
its d
Explanation:
lol im pretty sure im right but i could be wrong
The theory behind the formation of helium and gold is the fusing of hydrogen nuclei results in the formation of a light element like helium. One proton makes up the hydrogen nucleus. New helium atoms are created when protons combine. When helium atoms combine through enough consecutive collisions, as occurs during a supernova, they combine to generate heavier metals like gold. The correct option is 4.
What is fusion?
Fusion is a process in which two nuclei combine to form a large, heavier nucleus. This is a nuclear reaction. Nuclear reactions are of two types, fission, and fusion.
Smaller element or lighter elements like hydrogen and helium are formed by the process of nuclear fission, in which the division of element occur from smaller nuclei.
Heavier elements are formed by the process of nuclear fusion. Where lighter elements joined to create heavier elements.
Thus, the correct option is 4.

An enzyme is a protein that facilitates certain cell processes makes the DNA molecule split up into two strands.
What does this enzyme (helicase) do to the DNA molecule?
DNA moves the nitrogenous bases, helping them to attach to the proper molecule. Complete the 2 molecules of DNA by dragging nucleotides to their corresponding locations.
The DNA enzyme helicase unzips the DNA strand in order that one side is often used as a template to form a replacement strand. DNA polymerase is another enzyme that takes nucleotides from the solution and bonds them to other nucleotides.
DNA helicase unwinds the double helix at the replication fork.
Therefore, the DNA molecule split up into two strands.

Which of these might result from the process of natural eutrophication?
A pond becomes a meadow.
B rock breaks down into soil.
C glacier retreats to expose new land.
D nonnative species takes resources from native species.
Answer:
AaaaaaaaaaaaAaaaaaaaaaaa
Pond becomes a meadow as a result from the process of natural eutrophication.
What is eutrophication?"Eutrophication is the gradual enrichment of a body of water, or parts of it, with minerals and nutrients, mainly nitrogen and phosphorus, resulting in abundant growth of simple plant life."Excessive plant production, damaging algae blooms, a rise in the frequency of anoxic occurrences, and fish fatalities are all consequences of eutrophication. What is a meadow?"It is a piece of low ground near a river."Layers of detritus accumulate when pond plants develop, die, and disintegrate and there is an increase in the level of nutrients. Over time, these layers of decaying debris rise the pond floor. The pond floor eventually gets near enough to the bottom that emergents can grow all the way across it. The ponds develop marsh meadows as a result of this.
Hence, the correct option is A. Pond becomes a meadow.

(ii) Which organ in the male body produces cell C from cell A?
Answer:
It would be Meiosis, since diploid cells gets cut which turns into haploid cells. Even though sperm and egg production is differ. They still follow the same process. -maclittleseed
Explanation:
The type of cell division is Meiosis and the male gamete produces cell C from cell A.
What are the different stages of meiosis ?The meiosis is a type of cell division which is up two types such as Meiosis I and Meiosis II, subdivided into sub phases. In prophase I disintegration in nuclear envelope, chromosomes condensed and Spindle fibres formation occur.
In Prometaphase II, Spindle fibres bind at the centromere to the chromosome where as in Metaphase I, homologous chromosomes align at the equatorial plate.
Anaphase I in which chromosomes passes towards the opposite poles and In Telophase I, Spindle fibres disappear, reformation of Nuclear envelope occur followed by Cytokinesis.

This stage is known as which of the following?
Water-holding capacity
O Field capacity
O Wilting point
O Desiccation
Answer:
Wilting point
Explanation:
Wilting point is defined as the minimum amount of water in the soil that the plant requires not to wilt. If the soil water content decreases to this or any lower point a plant wilts and can no longer recover its turgidity when placed in a saturated atmosphere for 12 hours.

ANSWER QUCK PLS Why is it important for a cell membrane to be selectively permeable?
Answer:why is it important that the cell membrane is semi permeable? ... The solution around the cell has a lower concentration of solutes and a higher concentration of water than the inside of the cell. The cell gains water and swells. Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively.

Explanation:
That is all I can think of
The rock cycle is a process in which the three types of rocks—igneous, sedimentary, and metamorphic—are continuously changed.
What is a rock cycle?The rock cycle explains how different types of rocks, such as sedimentary, igneous, and metamorphic rocks, change through time. These rocks are present in the lithosphere, which makes up the crust of the earth, but they are not evenly dispersed or spaced.
The soils are created from the weathered and eroded rocks. The rock cycle demonstrates how various types of rocks that enter and exit this cycle change and adapt.
Therefore, some rocks are 4.6 billion years old and other rocks are only 2 billion years old, while yet others are only a few thousand years old based on radiometric dating.

A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?
1.geotropism and phototropism
2. phototropism and thigmotropism
3. hydrotropism and geotropism
4.hydrotropism and thigmotropism
Answer:
4
Explanation:
The correct answer would be hydrotropism and thigmotropism.
Hydrotropism is defined as the movement of a plant or its organs to or away from moisture. The deep root growth of plants is a way of seeking or growing towards moisture that is present deep in the soil. Hence, the root is said to exhibit positive hydrotropism.
Thigmotropism, on the other hand, is the growth or movement of plants or their organs to or away from touches. In this case, the tendrils of the plant that wraps around objects they come in contact with are showing positive thigmotropism.
The correct option is, therefore, option 4.
