Answer:
Gene; alleles; heterozygous; dominant; recessive; homo-zygous.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Filling up the blanks in the question, we have;
A gene is a series of nucleotides that encodes a protein product. This coding DNA may have different forms, or varieties, called alleles. An individual with two different versions of a gene is genetically heterozygous. In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene will be visible. The other form of the gene is recessive: it confers a trait that is only visible when the individual is genetically homo-zygous, or has two identical copies of the gene.
What would happen to a population if all females reproduce through parthenogenesis alone?
Answer:
All the offspring from parthenogenesis are female. So if the female stick insects carry on reproducing alone, the males could be wiped out. ... This may help explain why parthenogenesis remains rare, even in species that are capable of it. In such species, "males typically force females to mate".

Scientists have been studying four populations in a swamp area. In this area, alligators eat gar (a type of large fish), and both gar and diving ducks eat crabs. The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and the crab population will change, and why.
Answer:
There wouldn't be enough resources for the alligator population to live off of thus decreasing its population number. This decrease affects the other populations because it without alligators, its predators and prey wouldn't gain its nutrition from it and it would overall change its environments' habitation. The gar population would increase because they wouldn't be eaten by the alligators and therefore increasing the diving duck population as well. The crab population would decrease because the gar (their prey) population increased which overcomes the number of crab in the population.

Explanation:
To guarantee senators' independence from short-term political pressures, the framers designed a six-year Senate term, three times as long as that of popularly elected members of the House of Representatives. Madison reasoned that longer terms would provide stability.
Natural selection causes changes in? A.genotypes. B.populations. C.individuals. D.phenotypes.
Answer:
populations
Explanation:
A) genotypes
Natural selection may happen because of different genotypes (for example, heterozygous individuals survive better). Natural selection does not change genotype.
Recall that genotype is the type of alleles one has.
B) populations
Natural selection is the survival of the fittest. For example, a drought. Or predators. Or limited food supply. Or overproduction. All will end up with the stronger, better-surviving types of a certain population. Natural selection does change populations.
C) individuals
Natural selection usually occurs when there are large amounts of a certain type of individual (for example, bunnies). They usually do not affect individuals.
D) phenotypes
Natural selection may happen because of different phenotypes (for example, green grasshoppers survive better than red ones). Natural selection does not change phenotype.
Recall that phenotype is the physical appearance one has.
Extra:
Phenotype vs. Genotype:
If A is dominant for brown hair and a is recessive for albino hair:
Genotype Aa has a phenotype of brown hair.
Genotype AA has the phenotype of brown hair.
Genotype aa has the phenotype of albino hair.
You can see how genotype and phenotype are like.
Natural selection causes changes in populations. The correct option is B.
What is natural selection?Natural selection is a biological mechanism that allows some organisms to survive and reproduce more successfully than others, resulting in the transfer of advantageous traits from one generation to the next.
Natural selection operates on the and phenotype genotype of the organism. It causes changes in the frequency of genes (genotype) in a population, which results in changes in the physical appearance (phenotype) of the population.
A population is a group of individuals of the same species living in the same geographical area at the same time. Natural selection affects populations, not individuals, as it occurs over several generations, and it results in changes in the allele frequencies in the population. Thus, natural selection causes changes in populations.
Therefore, the correct option is B.

A teacher asks students to make a model of a transform plate boundary. The students use blocks to represent tectonic plates and slide the blocks past each other in the directions of the arrows as shown. A teacher asks students to make a model of a transform plate boundary. The students use blocks to represent tectonic plates and slide the blocks past each other in the directions of the arrows as shown.
Answer:
The model is right.
Explanation:
The model made by the students about transform plate boundary is right because in the transform plate boundary, the tectonic plates moves horizontally by rubbing each other. As the tectonic plates rub against each other, huge stresses are created that can cause breaking the portions of the rock that results in earthquakes in that region. The area or regions where these breaking of rocks occur is known as faults. San Andreas Fault in California is the example of transform plate boundary.
Please help! I will give brainiest answer!
Answer:
D
Explanation:
The vehicles have the same amount of kinetic energy because they are travelling at the same speed. There is a great difference in their masses but their speed is same. Kinetic energy of a body depends on both mass and velocity. If the mass of an object increases, its kinetic energy also increases and vice versa while on the other hand, if we doubles the speed of an object its kinetic energy increases four times so we can conclude that objects having same speed leads to same kinetic energy.
A group of marine scientists introduced a species of fish into an artificial habitat and wanted to determine if it will grow well in the new environment. They recorded the population over several years and their data is plotted below. Analyze the data and formulate a conclusion. Does this species of fish do well in this habitat? Predict what will happen to the population over the next five years.
Answer: The graph appears to show an exponential growth among the school of fish. This is good for their species, because the artificial habitat suits their needs. The next five years would probably continue to grow this way if the environment doesn't change too rapidly.
Why is sexual reproduction associated with meiosis? meiosis reproduces identical DNA meiosis is the complete process of sexual reproduction meiosis helps to generate variability meiosis produces gametes
Answer:
meiosis produced gametes
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

What type of energy transformation takes place when a rose takes in energy from the soil and uses the energy to make its own food?
Answer:
plants use photosynthesis to make food.
Explanation:
Photosynthesis takes place in the specific cells of plants known as chloroplasts, which are the cell type found in leaves. A single chloroplast is like a suitcase full of major photosynthesis materials. It has water-soaked from the root of the plant, atmospheric leaf absorbed carbon dioxide and chlorophyll in softened, labyrinthine organelles known as Thylakoids.
The true catalyst for photosynthesis is chlorophyll. This light-sensitive molecule is used to stimulate the process by cyanobacteria, plankton, and terrestrial plants.
The chlorophyll molecules are so awful for the green light to absorb that they reflect it like small mirrors that cause the majority of the leaves to look green. In the autumn we only look at these limitless colors of yellow and orange formed in carotenoid pigments after chlorophyll degradation.

Los jugos gástricos presentes en el estómago tienen un pH de aproximadamente1.87 ¿Cuál es la concentración de iones H+ presentes en los jugos gástricos?
Answer:
1,35 * 10 ^ -2 M
Explanation:
Recuerde que pH = -log [H ^ +]
Sea la concentración de iones de hidrógeno [H ^ +]
Si es así, entonces;
-pH = log [H ^ +]
Por lo tanto;
[H ^ +] = Antilog (-pH)
[H ^ +] = Antilog (-1,87)
[H ^ +] = 1,35 * 10 ^ -2 M

Phase 1 of the creation of life on earth was the formation of small molecules containing carbon and hydrogen. Phase 2 was the formation of self-replicating, information-containing molecules. Phase 3 was: Please choose the correct answer from the following choices, and then select the submit answer button. the development of a nucleus, enabling metabolism and creating the first cells. the formation of DNA. the development of a membrane, enabling metabolism and creating the first cells. the formation of RNA. the cooling of the earth to a temperature conducive to life.
Answer:
the development of a membrane, enabling metabolism and creating the first cells.
Explanation:
In Abiogenesis (evolutionary biology), the formation of life on earth is described by three (3) main stages and these includes; phase 1, phase 2 and phase 3.
In phase 1, small molecules that comprises of carbon and hydrogen are formed on earth. The second phase is the formation of molecules that can be replicated by themselves and contains informations.
Phase 3 involves the development of a membrane, enabling metabolism and creating the first cells.
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.
Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles such as nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, and vesicles.
The regular sequence of growth and division that cells undergo is called the cell cycle. This cycle makes it possible for the cells found in living organisms to divide and produce new cells.
Basically, there are four (4) phases of the cell cycle and these are;
I. Prophase.
II. Metaphase.
III. Anaphase.
IV. Telophase.

In humans blood type A and B are equally dominant (codominant). Both types are dominant to type O. Aman with type AB blood marries a woman with type O blood, give the genotype and phenotype of all possible offsprings
Answer:
The correct answer would be -
Genotype: IAIO or IBIO
Phenotype: A Blood or B Blood
Explanation:
Blood group A and blood group B both are dominant over the blood group O, however, both A and B are codominant if present together and form the blood group AB.
The blood group of Aman is AB and If he marries the female with O blood group then possible blood group in offspring would be as follows:
gametes: Aman = IA and IB
woman = IO IO
then cross between:
IA IB
IO IAIO IBIO
IO IAIO IBIO
the genotype of this cross would be 50% chances of IAIO and 50% chances of IBIO and phenotype would be either Type A or type B.

How many days are in between moon phases, and if there was a new moon on March 17, when will the next new moon be?
Answer:
It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant “fixed” stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
