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 product of fermentation expands bread dough
Ethanol
Energy
Carbon dioxide
Carbon dioxide because During fermentation, carbon dioxide is produced and trapped as tiny pockets of air within the dough. This causes it to rise. During baking the carbon dioxide expands and causes the bread to rise further. The alcohol produced during fermentation evaporates during the bread baking process.

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.

A. C with C, and G with G
O B. C with T, and G with A
O c. C with A, and G with T
O D. C with G, and A with T
The correct pairing of DNA bases is D. C with G, and A with T. Thus, option "D" is correct.
What is DNA replication?DNA replication is a process of the formation of two molecules of DNA from a single DNA molecule (which is double-stranded).
In this process, the two DNA strands of the original DNA are first separated so that the template strands are exposed.
Thus, option "D" is correct.

The correct pairing of DNA bases is C with G, and A with T. Therefore option D is correct.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
In DNA, the bases always pair up in a specific way known as complementary base pairing. The bases adenine (A) and thymine (T) form a pair, and cytosine (C) and guanine (G) form a pair.
This pairing is based on the specific hydrogen bonding interactions between the bases:
Adenine (A) always pairs with thymine (T) through two hydrogen bonds.
Cytosine (C) always pairs with guanine (G) through three hydrogen bonds.
This specific pairing of bases is crucial for DNA replication and the accurate transmission of genetic information during cell division and protein synthesis.
The pairing of DNA bases: (D) C with G, and A with T. This pairing reflects the complementary base pairing rules observed in DNA.

Which of these best describes the tiny leg bones that some whales have, which do not aid in their movement or serve any other function?
O structures that grow and improve in function as they are used
O structures that function at certain times of the year or under certain conditions
O structures that will become adaptations when the environment changes
O structures that have lost all or most of their function over evolutionary time
Answer:
D. structures that have lost all or most of their function over evolutionary time
Explanation:
the question states that the leg bones are almost entirely unused because of evolution
The study of change over a period of time is called evolution.
The correct answer of the following is D.
The change in the species over the period of time is called evolution. It is necessary to adapt itself in order to survive in nature.
According to the lamark, it is said that the organs which are no longer used in the body will become vestigial and will be removed from the body over a period of time.
According to the question, the small bones in the whale is might have functioned in the ancestor period but not in the current time due to the course of the evolution.
Hence, the correct answer is D that structures that have lost all or most of their function over evolutionary time.

How does the DNA sequence in a normal hemoglobin gene compare to a sickle cell hemoglobin gene?
ASAP
Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.
Explanation:
The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.
What is Sickle cell anemia?Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.
Symptoms of sickle cell anemia include infections, pain and fatigue.
Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

How can a material at a certain temperature have all of its molecules at the same energy?
Answer:
The average kinetic energy of the molecules is proportional to absolute temperature. At any given temperature, the molecules of all gases have the same average kinetic energy.
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. Solids, liquids and gases all expand when heat is added.

Light Reactions : ATP :: Calvin Cycle :
a. G3P
b. H2O
c. O2
d. H+
Answer:
a. G3P
Explanation:
Photosynthesis is the process by which plants synthesize their food from inorganic sources in the presence of light. The photosynthetic process occurs in two stages namely: light dependent stage (light reaction) and light independent stage (Calvin cycle).
The light stage primarily functions to synthesize ATP and NADPH products needed in the Calvin cycle to synthesize sugar (glucose). However, the CALVIN CYCLE produces a three-carbon compound called GLYCERALDEHYDE-3-PHOSPHATE (G-3-P) as one of the precursors of glucose.
