In simple dominance, what is the result when a dominant allele pairs up with a recessive allele?
Offspring display both forms of the trait.
Offspring display an intermediate form of the trait.
The dominant form of the trait shows.
The recessive form of the trait shows.
In most cases, the dominant form of the trait shows.
Answer:
Option C, The dominant form of the trait shows
Explanation:
In simple dominance the trait associated with the dominant allele is expressed while the trait associated with the recessive allele is oppressed. For example –
Let’s assume a flower in which the dominant allele trait is red color and the recessive allele trait is white color. When an offspring of this flower is produced containing one dominant allele and one recessive allele, the color of it would be red only because only the dominant allele expresses its trait.
Hence the correct answer is option C
carbon has six proteins, six neutrons, and six electrons. Oxygen has eight protons, eight neutrons and eight electrons.
Carbon which has six protons,electrons but may not have six neutrons because to determine the number of neutrons you need to know the atomic number(i.e number of protons/electrons) and the mass number.
Neutron number=Mass number-Atomic number
The same applies to oxygen.
Carbon dioxide and oxygen have different atomic numbers.
What is the atomic number?The number of protons in an atom's nucleus, which is a chemical element's defining feature and determines its position in the periodic table is called as the atomic number.
Each kind of atom has a different number of the three particles. Protons and neutrons are in the center, or nucleus, of the atom. Carbon has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons. Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles.

What is the main type of weathering in deserts?
physical weathering
chemical weathering
weathering by organic acids
Answer:
The major type of weathering that takes place in a desert in Physical Weathering.
Explanation:
Physical weathering also known as mechanical weathering takes place in deserts. This weathering takes place due to physical or mechanical forces. Frost chattering, temperature fluctuation also causes physical weathering.
In the desert, there is a fluctuation in temperature. In deserts, the temperature during the day will be very high and at night the temperature will be very low. As a result, the rocks expand during daytime due to heating and at night the rocks undergo contraction due to the reduction in temperature. Hence the rocks are weakened followed by the disintegration or breaking of rock.
Answer:

Human heart is divided into four chambers: two atrium and two ventricles. The ventricle is located at the bottom of the heart.
The given diagram correspond to the lining of the heart ventricle. The pulmonary circulation of the heart to the lungs occur through the right ventricle. The wall of the ventricles are thicker than atria.
Thus, the correct answer is option (3).
Muscle A is found in the lining of a heart ventricle.
What are the characteristics of heart muscles?The human heart contains cardiac muscle, often known as the myocardium. Cardiovascular muscle is controlled by an involuntary force.There are three layers that make up the heart: the pericardium, myocardium, and endocardium. Heart muscle is not found in the endocardium. The inner lining of the heart chambers and valves is made up of simple squamous epithelial cells. The epicardium, pericardial space, parietal pericardium, and fibrous pericardium are all components of the pericardium, a fibrous sac that surrounds the heart.The contractility of the heart and consequent pumping motion is caused by the cardiac muscle. The heart muscle must contract with sufficient force and blood flow to meet the body's metabolic needs. The formula for this idea, known as cardiac output, is heart rate x stroke volume.It is based on the heart muscle's ability to contract and how frequently that ability is used. The metabolic demand changes along with the heart's ability to contract.

A scientist crossed a pea plant with a green pod and a pea plant with a yellow pod. The scientist collected 100 seeds from the cross. The table shows the trait for pod color observed when the plants from the cross were grown. Which statement correctly explains why all the offspring have the trait for a Yellow pod? A) Genes were inherited only from the plant with a Yellow pod, so only the gene for a Yellow pod was expressed.
B) Genes were inherited only from the plant with a Green pod, but only the gene for a Yellow pod was expressed.
C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.
D) Genes for both a Green pod and a Yellow pod were inherited, so the genes for both types of pods were expressed.
Answer: C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.
Explanation: In a diploid organism as the pea plant, a single gene has two alleles or versions, one on each chromosome. Each of these alleles can either be dominant or recessive.
Dominant alleles, such as that producing a yellow pod, will mask the contribution to the phenotype of the second allele, which is recessive. Here, the yellow pod allele will mask the contribution of the green pod allele. Thus, the offspring will have the phenotype (pod color) yellow.
However, both alleles for pod color will be present in the offspring as each parent will provide one chromosome during sexual reproduction.

What is the relationship between DNA, codons, and proteins
the relationship between DNA, codons, amino acids, and proteins. During transcription, DNA is transcribed into messenger RNA when the the base codes in DNA are copied. mRNA serves as the code for assembling amino acids in a certain order.
The genetic information encoded in the nucleotide sequence flow from DNA to codons of the mRNA sequence and then from the mRNA to protein.
During gene transcription, a specific DNA sequence is used to create a complementary RNA sequence called messenger RNA (mRNA).Subsequently, this mRNA is used as a template to create a protein by a mechanism called translation.The linear order of triplets of nucleotides or 'codons' in mRNA determines the order of amino acids in the growing polypeptide chains (i.e., the protein).In conclusion, the genetic information encoded in the nucleotide sequence flow from DNA to codons of the mRNA sequence and then from the mRNA to protein.

in the process of___, a protein channel helps the diffusion of glucose across the membrane
Facilitated Diffusion
Facilitated diffusion is the type of diffusion in which the molecules are transported across the channels with the help of transport molecules. Facilitated diffusion is the answer.
What are types of facilitated diffusion ?The types of facilitated diffusion are carrier protein transport and the ion channel transport proteins.
In the process of the facilitated diffusion various molecules are diffused across plasma membrane with help from the membrane proteins such as the channels with carriers. A concentration's gradient lives for these molecules such that they all have potential in order to diffuse in (or out of) cell by just moving down it.
Facilitated diffusion thus allows polar with the charged molecules such as the carbohydrates, amino acids , nucleoside and the ions for crossing the plasma membrane. Two main classes of the proteins that helps facilitated diffusion are generally described as : carrier proteins and the channel proteins.

What natural factors do scientists study to understand long-term climate change? Check all that apply.
Earth’s position
pollen grains
tectonic activity
volcanic activity
solar energy
the answer is :
1)Earth’s position
3)tectonic activity
4)volcanic activity
5)solar energy
Answer:
Options (1), (3), (4) and (5)
Explanation:
The factors that are needed to study in order to understand better about the long-term climate changes are the position of the earth with respect to the sun, type, and intensity of the tectonic and volcanic activities and also the amount of solar energy entering into the earth's atmosphere.
If the position of the earth changes with respect to the sun and also if changes occur in its plane of orbit, then there will be significant changes in the climate of the earth.
Rapid and high intensity tectonic and volcanic activities can also lead to the increase in the earth's global temperature as it will produce a large amount of gases and dust particles from the volcanoes that are trapped in the atmosphere and does not allow the sunlight to reach the ground surface. Thus, affecting the earth's climate.
The increasing amount of solar radiation can also enhance the earth's climate as it will significantly warm the surface of the earth.
Thus, the correct answers are options (1), (3), (4) and (5).

Example of sex linked traits
male tesosterone can affect facial hair, voice deepness, testicle size, muscle mass, agressiveness, etc
Sex-linked traits are determined by genes located on sex chromosomes. In humans, examples of sex-linked traits include certain conditions such as color blindness, hemophilia, and muscular dystrophy. These traits are more common in males because they receive one X chromosome from their mother, which if contains the recessive X-linked trait, it's expressed in males.
Explanation:Sex-linked traits are characteristics determined by genes located on the sex chromosomes. These traits tend to express differently in males and females due to the difference in the sex chromosome composition, XY in males and XX in females.
Examples of sex-linked traits can be seen in human genetics, where the alleles for certain conditions such as color blindness, hemophilia, and muscular dystrophy are X-linked. When a female parent who is homozygous for a recessive X-linked trait, she will pass the trait on to 100 percent of her male offspring, as they inherit their father's Y chromosome.
In addition, females who are heterozygous for these diseases are referred to as carriers, may not show any phenotypic effects, but will pass the disease to half of their sons and carrier status to half of their daughters. Thus, recessive X-linked traits tend to appear more frequently in males than females.
