Radish color is controlled by a gene that exhibits incomplete dominance; purebred red radishes (RR) crossed with purebred white radishes (WW) make purple radishes (RW). What are the chances of producing purple offspring when you cross two purple parents?
Answers
Answer:
1/2
Explanation:
This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).
If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.
Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:
RR - red = 1/4
RW - purple = 2/4 or 1/2
WW - white = 1/4
Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.

the cells were kept in a dilute solution. they were then transferred to distilled water. explain what will happen to each of these two cells when they are placed into distilled water.
Answers
When you place the animal cell in distilled water, because distilled water is a hypotonic solution(has a lower concentration than the cytoplasm). Water will diffuse inside the cell through osmosis. This will cause the cell to swell and eventually burst.
When you place the plant cell in the distilled water. The water will diffuse inside the cell, the water will build up inside the vacuole and turgor pressure will appear. The cell won't be able to burst because the cell wall prevents it.

Answers
Answer:
Light energy is converted to chemical energy.
Please find the explanation below
Explanation:
Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.
The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.

How does the cooling rate of magma affect the
texture of igneous rock?
Answers
Answer:
The factor that affects the size of the crystals and the texture of the rock is the cooling rate of the molten rock or magma. If the magma cools rapidly, the crystal formed is very small. ... On the other hand, if the magma cools slowly, the crystal formed is large. This rock has a coarse-grained texture.
Explanation:
The texture of an igneous rock is completely dependent on the rate of cooling of the melt. Slow cooling allows large crystals to form whereas fast cooling gives small crystals.
How is cooling rate of magma related to texture of igneous rock?If the magma cools quickly then the reactions are much more faster and smaller mineral crystals. Igneous rocks have a distinctive appearance based on the rate of cooling.
Cooling rate of the molten rock or magma is the factor that mainly affects the size of the crystals and texture of the rock. Crystal formed is very small, when the magma cools rapidly whereas, the crystal formed is large, if the magma cools slowly.
Rocks formed from the crystallization of a liquid are called Igneous rocks. Igneous rocks are divided into:
Intrusive rocks that crystallize from magma in the earth's crust. Extrusive rocks that crystallize from lava in the earth's crust.To know more about igneous rock, refer

Also since cells replicate incredibly fast, procedures wouldn't need many cells depending on the case. Stem cell research can vary in costs from about $5000 to $20,000 which for many people is difficult because stem cells are very temporary in many cases.

uncontrolled cell division can lead to the formation of masses of cells that can remain in place called ____ tumors or ones that can move called ___ tumors
Answers
Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called primary tumors or ones that can move called metastatic tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.
