How is the proportion of hydrogen to helium in the Sun's core changing over time?
Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.
Explanation:
The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.
What color light is being reflected by green plants?

As such, plants look green because they absorb red light most efficiently and the green light is reflected.
Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity?
Answer:
The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Explanation:
As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.

Answer:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

1. An unstable nucleus releases radiation in the form of a helium particle. What process is occurring!
a) Fusion
b) Fission
c) Alpha Decay
d) Beta Decay
An unstable nucleus with too many protons emits energy and an alpha particle during alpha decay. An alpha particle is actually a helium nucleus because it has two protons and two neutrons. A nuclear equation can be used to represent alpha decay. Thus, option C is correct.
What is the alpha decay releases of radiation from helium?When an unstable nucleus changes to another element, a nuclear process called “alpha decay” produces a particle consisting of two protons and two neutrons. The helium nucleus that is being ejected is known as an alpha particle.
An alpha particle is released when a nucleus becomes unstable due to having an excessive number of protons. An alpha particle is a helium nucleus, since it has two protons and two neutrons. This is the alpha decay.
Therefore, Each of the two protons and two neutrons that make up an alpha particle is a helium nucleus that has lost its planetary electrons.

O A. The Kuiper belt
OB. The asteroid belt
O C. The terrestrial belt
OD. The comet belt
Answer:
asteroid belt
Explanation:
region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started. However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet.

Which of the following best describes DNA in a prokaryotic cell?
Which process has evolved to yield the GREATEST variation of offspring?
A.Meiosis
B.Mitosis
C.Replication
Meiosis has evolved to produce the greatest variation of offspring.
What is meiosis?Meiosis is a type of cell division that occurs in eukaryotic cells, such as those in animals and plants, to produce reproductive cells (gametes) that have half the number of chromosomes as the parent cell.
During meiosis, chromosomes pair up and genetic material through a process called crossing over, creating genetic diversity among the gametes. This diversity increases the chances that at least one offspring will be better suited to its environment and increase the survival chances of the species.

Answer: see below
Explanation:
So, kinetic energy means an object is already in motion. Potential energy, means an object has the potential to transfer energy but is idle. Mechanical energy is something like a wheel turning. That is also correlated with kinetic energy. Which in turn, means when a wheel rotates, the object is in motion. Therefore transferring energy.

Explain how the sugars, phosphates, and nitrogenous bases in one strand of DNA connect to a complementary strand during replication
Answer: One strand of DNA binds to another via base complementarity.
Explanation:
The two strands of the DNA double helix are connected through nucleotides. There are hydrogen bonds between the nitrogenous bases. Each nucleotide has a sugar, nitrogenous base and phosphate group. The phosphate group and sugar forms the backbone of the DNA double helix. The nitrogenous base form pairing with each other via base complementarity. Purines are adenine and guanine and pyrimidine are cytosine and thymine these are nitrogenous bases. The adenine bonded with thymine via two hydrogen bonds and cytosine with guanine with three hydrogen bonds. These nitrogenous bases help in replication process.
The two strands of DNA are actually connected by hydrogen bonds (H-bonds) between the nitrogenous bases.
There are 2 hydrogen bonds between adenine and thymine, and 3 hydrogen bonds between cytosine and guanine.
Why are sugar-phosphate and nitrogenous bases important to DNA molecules?The sugar-phosphate backbone is a significant component of DNA's double helix structure.
The structure of DNA is tied to its function. The pairing of the nitrogenous bases that are connected to the sugar-phosphate backbone play a key role in the ability of DNA to store and transfer genetic information.
Thus, base complementary is the reason.
