What evidence best supports the conclusion that all cells have the same DNA?
A.
Fertilization produces one cell, and that cell divides by mitosis.
B.
Different types of cells produces different proteins.
C.
Organisms have different specialized cells.
D.
a cell’s genetic makeup
Final answer:
The evidence that all cells have the same DNA is that they all originate from a single cell created by fertilization, which then divides by mitosis. Differentiation enables these genetically identical cells to develop unique functions and structures by selectively expressing certain genes.(Option A)
Explanation:
The evidence that best supports the conclusion that all cells have the same DNA is A. Fertilization produces one cell, and that cell divides by mitosis. Mitosis is a process that ensures each new cell will have an identical set of chromosomes and, therefore, the same DNA as the parent cell. During development, all cells in a multicellular organism originate from this single fertilized egg, resulting in each cell containing the same genetic material. However, differentiation plays a crucial role in how these cells with identical DNA can develop into various types with distinct structures and functions.
Differentiation refers to the process by which cells become specialized in size, shape, metabolic activity, and function. Although each cell has the complete set of DNA, like actors reading different parts of the same script, they only 'read' or express the DNA sections relevant to their specific function. This selective expression of genes leads to the diverse cell types that form tissues such as skin, muscle, bone, and nerves.
Which is the main function of fruit?
To protect the seed and aid in its dispersal
To protect the flower and aid in pollination
To protect the seed and aid in germination
Answer: To protect the seed and aid in its dispersal
Fruit is a plant organ that is a characteristic feature of all the angiosperm plants. It is produced by the pollination and fertilization of the flower. The fruits comes in variety of shape, size and color. They are the products of fertilized ovary and other floral parts. Fruits can be fleshy or dry. Main function of the fruit is to provide a space of the growth and development of seeds until maturity. In maturity the fruit disperse seeds which germinate to grow into new plants.

What are the basic steps of the water cycle
The basic steps of the water cycle include evaporation and transpiration, condensation, precipitation, infiltration and groundwater flow, and surface runoff, driven by the sun's energy and involving state changes of water.
The water cycle is a critical continuous process in Earth's ecosystem, describing the movement of water molecules through various states and locations.
This cycle is driven by the sun's energy, which heats up water in oceans and surface waters, initiating evaporation and sublimation. These processes result in water vapor entering the atmosphere. The next phase involves condensation, where water vapor forms clouds composed of liquid or frozen droplets.
Following condensation is precipitation such as rain or snow, returning water back to the Earth's surface. Some of this water will seep into the ground (infiltration), while other portions may return to the atmosphere or contribute to surface runoff, eventually reaching rivers, lakes, and oceans.
More specifically, the basic steps in the water cycle include:
Evaporation: The transformation of water from liquid to vapor due to heat from the sun.Transpiration: The release of water vapor from plants and vegetation into the atmosphere.Condensation: Water vapor cooling and changing back into liquid form, forming clouds.Precipitation: The process of water, in liquid or solid form, falling from clouds to the surface of the Earth.Infiltration and Groundwater Flow: Water soaking into the soil and moving through the ground, potentially re-entering the cycle through evaporation.Surface Runoff: Water flowing across the land, eventually reaching bodies of water like rivers and oceans.The main purpose of models is to gain a better understanding of the world. T/F
The answer would be:
TRUE
You can learn more about models if you read on:
Models aim to gain a better understanding of an aspect or feature of the world by making it easier to visualize, define, quantify and the like by referencing it to something more commonly accepted by all. There are different types of models and each can be used depending on the aim.
If you want people to better quantify a certain aspect, then mathematical models can be used. If you want people to better visualize a certain aspect of the world, then graphical models be best. These are just some examples of models.
Scientists have studied the fossilized shells of prehistoric, single-celled marine organisms. Some of these shells were thin, which indicates that the organisms lived in very warm ocean water. Such evidence indicates that the climate during this time may have been

Which of the following identifies the purpose of anaerobic fermentation within the body?
a. converts lactic acid to pyruvate for use in the Krebs cycle
b. creates large amounts of ATP for cells to use as a direct energy source
c. produces short-term energy for the cells when oxygen is not available
d. transfers NADH and FADH2 for use in the electron transport chain
The correct answer is (c) Produces short-term energy for the cells when oxygen is not available
The anaerobic fermentation is needed by the body when there is depletion in oxygen level. When the body is in normal conditions, sufficient amount of oxygen is present then aerobic respiration takes place. When there is a condition that the requirement of oxygen is not fulfilled then body shifts to anaerobic fermentation for a short period of time, then it returns back to the normal conditions.

What is the role of a pioneer species in primary succession?
to destroy parasites
to create shade
to provide fruit
to create the soil
Answer: to create the soil
Explanation:
An ecological succession can be define as a series of changes that occur in the biotic community with respect to the changes that occur in the abiotic or non living factors such as soil, temperature, water, natural calamity and others in a particular time duration until the ecosystem attains stability.
A primary succession is an initial stage of succession which occurs in a land which was not previously occupied by any living species and the physical environment is not favorable to support the life initially. A pioneer species is the one which makes the environment suitable for the survival of other species. For example Lichens, they secrete acids over the rocks which causes their disintegration into particles of soil. The accumulation of soil facilitates the growth of the plants.
The class of macromolecule that would most likely be involved in contracting muscles would be___
A. Lipids
B. Proteins
C. Enzymes
D. Carbohydrates
Answer:
The correct answer is option - B. proteins.
Explanation:
The muscle contraction needs two protein that is essential in contraction. The muscle has motor protein myosin and spherical protein actin that are slide on one other in contraction that helps in muscle to contraction.
In the contraction, these protein filaments help to change in length and shape of the muscles. Thin filaments involve actin and thick filament in is myosin filaments.
Thus, the correct answer is option - b. proteins.

What is the difference between active transport and passive?
Recent volcanic activity in different parts of the world supports the inference that volcanoes are located mainly in
1)the centers of landscape regions
2) the central regions of the continents
3) zones of crustal activity
4) zones in late stages of erosion
Answer: Option (3)
Explanation: Zones of crustal activity is also known as the tectonic activities. This is the region, where plates undergoes convergent, divergent or transform movement.
These volcanoes are formed when plates undergoes collision, that means convergent plate boundary, where the denser plate gets subducted beneath the less denser plate.
And the data collected by studying about the different volcanoes, helped in the determining that the volcanoes are mostly located at the zone where crustal activities constantly goes on.
Thus, the correct answer is option (3).
A mineral that does not split apart evenly has the property of fracture
True or false
The given statement is True.
In mineralogy, fracture refers to the shape and texture of the surface of the rock produced when a mineral is fractured. Minerals generally exhibit a highly distinguishing fracture, making it the main character used in their determination.
Fracture varies from cleavage, in cleavage clean splitting along the plane of cleavage takes place in the mineral's crystal structure, which is in contrast to more usual breakage.
