Answer:
Explanation:
Polydactyly is a mutation, it is a sudden change that can be heritable that occurs.
Because mutation does not always occur the chances of having large number of people having the traits in a dominant form is low, hence more people will have normal finger.
Dominance is not the number of time a traits occur, it is the ability of a allele to be expressed over another. The expressed allele i.e that is seen in the phenotype of such individual is the dominant allele while recessive allele are the one whose effect are mask.
Having a round eye is an example of a recessive traits that people posses but are expressed in some individual.

What is the locomotory structure of yeast
Answer:
Yeast cell structure
Each yeast cell has a distinct cell wall enclosing granular cytoplasm, within which can be seen a large vacoule and a nucleus (Fig. 214). The vacuole varies much in size according to the state of activity of the cell.
Yeast contains almost the same organelles of a mature eukaryotic cell. Nucleus, Golgi apparatus, mitochondria, endoplasmic reticulum, vacuole, and cytoskeleton are the most important one. Yeast cell particle size is typically of 5×10μm.
Explanation:
Yet, we don't always think of yeast as something remarkable. Instead, it's often perceived as plain or dull—a single-celled organism that, like a plant, lacks the ability to move on its own accord.

Explain how water can be a destructive and constructive force.
Answer:
Water as a constructive force: It is involved in the deposition of sediments. It transports rock fragments, soil, and other debris at a particular area. This process eventually causes them to accumulate and form land features. Water as a destructive force: It is involved in weathering and erosion.
Explanation:
(pls mark brainliest if u can)
:)
Water can be both a destructive and a constructive force.
• The forces, which form or create an existing landform are known as the constructive forces. While the force, which tears or lowers down the surface features of the Earth are known as the destructive forces.
• Water can be considered as the constructive force as it carries sediment down the river and with the river becoming shallow, the deposition of the sediments takes place giving rise to landforms called deltas.
• On the other hand, water can also be considered as a destructive force as it takes part in processes like erosion and weathering. It breaks down and wears away the rocks and land masses.
Thus, water can be both destructive and constructive.

Describe the transportation system in plants .
Answer:
Transportation System in PlantsTransportation Of Materials In PlantsAll living organism need some method of moving substances from one part of the body to other parts of the body. For example, in living organisms food and oxygen are moved in the body to all the cells and waste materials such as carbon dioxide is taken away from them. The system of moving substances in different parts of body is called transport system. In plants, food and water are transported by bundles of tubes present in stem called phloem and xylem. In animals, food, water and respiratory gases (oxygen and carbon dioxide) and other substances are transported by blood.
In plants, transport system is not complicated as in animals. The transport system in plants consists of bundles of tubes in the stem, branches and roots. These tubes are called xylem and phloem. The main function of xylem is to transport water and dissolved minerals from the roots to rest of the plant body. While, the phloem transports the food manufactured in the leaves to all parts of the plant.

Plants are composed of eukaryotic cells.
Answer:
Plants are composed of eukaryotic cells.
Explanation:
Eukaryotic cells (as opposed to prokaryotic cells) have internal, membrane-bound organelles and a distinct nucleus that physically separates the genetic material of the cell from the all of the other parts of the cell. All protists, fungi, plants, and animals are composed of eukaryotic cells.
The characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]Plants are eukaryotic in nature and have a double membrane cell organelle that is known as Chloroplast. These cell organelles have a green-colored pigment known as chlorophyll that captures the sunlight and converts it into chemical form and accomplishes the process of photosynthesis.
Therefore, the characteristic that is most unique to plants is that they undergo the process of photosynthesis. Thus, the correct option for this question is B.

what are the four layers that make up the earth?
Answer: The 4 layers that make up the earth is the crust, mantle, inner core and outer core.
Explanation: The crust, which is a main layer is where we live on. Without the crust, we'll be standing on the mantle! The temperate of the crust is 392 Fahrenheit! The crust is 30 km thick. The mantle is the second layer of the earth. It's below the crust and it's hot, dense and semi-solid. It's mostly made of iron, magnesium and silicon. It can reach as hot as 1000 Celsius (1832 Fahrenheit)! It's about 2900 km thick! Anyone who standing on it will melt! The inner core is the 3rd layer. It's below the mantle and made out of liquid iron (molten iron) and nickel. It is about 5,200 Celsius (9392 Fahrenheit). Now that is hot! Hotter than a fire even a heater! The last layer is the outer core. It's made out of liquid iron and nickel, like the inner core. The outer core can be as hot as 5500 Celsius (8132 to 9932 Fahrenheit!)

when the body removes carbon dioxide bu the way of respiratory system what happens to the ph of blood
the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.
so the pH increases
When the body removes carbon dioxide, the PH of blood increases
The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.
The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.
When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.

A. can accelerate faster than the other two vehicles
B. is travelling in the opposite direction from the other two vehicles
C. is travelling on a curve in the road
D. needs a large amount of force to move
Answer:
C. Is travelling on a curve in the road.
Explanation: the two vehicles behind the truck is moving at a constant speed because there is no change in velocity. The truck is changing directions AND speed (Acceleration/Velocity).
The pickup truck has a changing velocity because the pickup truck- truck is travelling on a curve in the road.
What is velocity?Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time (e.g. 60 km/h northbound).
Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies. Velocity is a physical vector quantity; both magnitude and direction are needed to define it.
The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s−1).

What is an advantage and disadvantage of using 4.5-7.5 pH paper?
Answer:
The correct answer would be:
Advantage: helps in finding the exact ph value with a narrower range.
Disadvantage: You don't know the exact ph value on a regular scale.
Explanation:
The pH paper is a pH paper with a color indicator that helps in determining the pH value precisely between the 4.5 to 7.5 pH range. It is accurate in comparison to other pH papers such as 0-14 paper. One no need to guess the color between the different colors from various color mixtures as it has a more precise color reading that helps in finding accurate pH value in a narrow range.
On a regular scale, it is not as accurate and one can not find the exact value as it provides a narrow range value between 4.5 to 7.5.

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.
