a. New cells come only from existing cells.
b. The basic unit of structure and function in an organism are cells
c. All cells are identical
d. All living things are made up of one or more cells
Answer:
c) All cells are identical
Answer:
c. All cells are identical
Explanation:
The three statements are all living things are composed of cells, that cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.
And not all cells are identical as there are different types of cells in the human body and there are different organisms.
which of the following can be changed during meiosis? Is it a base sequence, a number of amino acids, a number of chromosomes, or a gene sequence
Answer:
Number of chromosomes
Explanation:
Meiosis is a specialized type of cell division in which the gametes are produced.
A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.
Therefore, meiosis changes the number of chromosomes.

What is unique about obtaining water from an artesian well?
O The water is heated by magma or hot rocks.
O The water is found in an impermeable layer.
O The water is under pressure naturally and no pump is needed.
O Amechanical pump must be installed to bring water to the surface.
Answer:
c-The water is under pressure naturally and no pump is needed.
Explanation:
Water from Artesian well is the water is under pressure naturally and no pump is needed.
What is Artesian well?A well from which water flows under natural pressure without the need for pumping is known as an artesian well.
It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.
Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).
Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.
The ability to collect water is what distinguishes artesian wells.
The water is under pressure naturally and no pump is needed.
Pumping water isn't essential because there isn't any pressure in the water.
Hence, the correct option is C.

The graph shows the results of an investigation into the effect of distance from a light source on the rate of photosynthesis. Based on the data represented in the graph, the rate of photosynthesis_______1______ as the level of available _____2_______ increases. The greatest change in the rate of photosynthesis occurs when the light level is __________3__________. Which table contains the numbers and terms that correctly complete the statements?
Answer:
A:
increaseslightlowExplanation:
Photosynthesis is a chemical process in plants and other primary producers that is integral to energy production. Carbohydrates containing energy is made from light, water and carbon dioxide in the form of glucose molecules.
As a result, the waste product oxygen is released. Photosynthesis is a rate-limited reaction, depending on many factors, including the concentration of carbon dioxide, atmospheric temperature and intensity of light. Because the energy needed is derived from photons, i.e. light particles, lower light intensities lower the rate of photosynthesis significantly.
what do you think the rock in Earth’s mantle is like? Is the mantle made of hard, solid rock or soft, solid rock? Explain your ideas.
Answer:
If the mantle is made out of soft rock, then I think it would melt due to the heat, but if it was hard, it would just burn, so I firmly believe the rock is hard.
Explanation:
Mantle is a layer on planetary body which is made up of minerals. Mantle is solid as it is made up of heavy metals and solid rocks which makes it rigid.
What is Mantle?A mantle is a layer inside a planetary body bounded by a core and on the above by a crust. Mantle is made up of rock or ices, and is generally the largest and most massive layer of any planetary body. Mantles are on the planetary bodies that have undergone differentiation by density.
The mantle is composed primarily of heavy metals, such as iron, nickel, and others. The state of the mantle was described as plastic. Many divide the mantle into further such as the asthenosphere and lithosphere.
Mantle rocks are soft and able to move over the course of millions of years at great depth and pressure. The transfer of heat and material in the mantle helps to determine the landscape of the planet.
