Answer:
It is possible if 1 or both parents have the blue-eyed recessive allele
Explanation:
It works both ways.
B=Brown-Eyed Dominant Allele
b=Blue-Eyed Recessive Allele
Solution 1:
Bb x Bb
Using a Punnett Square (You can look up "Punnett Square calculator" online to find an example) you can find that there is a 25% chance for BB alleles in the offspring, 50% chance for Bb, and 25% chance for bb.
This shows it's possible for an offspring to have blue-eyes.
Solution 2:
BB x Bb
Using a Punnett Square you can find that there's a 50% chance for BB alleles in the offspring and a 50% chance for Bb.
This shows that it's possible for an offspring to have blue-eyes.

Explanation:
I Couldnt Tell What were The Object aside From The coffe--or was Number 3 not coffe?? - anyways That Is all I can answer
The following mixtures are made by mixing the components with each other.
What are mixtures?A mixture is a substance comprised of two or more additional chemical compounds or substances that do not chemically combine. It is really the physical blending of two or more substances such that they may still be distinguished from one another when combined as solutions, suspensions, or colloids. Physical means can be used to separate them. The different components of any combination are not created via any sort of chemical transformation. As a result, each component's unique qualities are unaltered.
A mixture's constituent parts also do not combine chemically to form a new material, in contrast to a compound. Instead, they just combine while retaining their individual traits. The lemonade seen above is a mixture since the ingredients are not present in predetermined amounts. Even though it has more or less sugar or lemon juice, it will still be referred to as lemonade.
Therefore, mixtures are made by mixing the components together.

A sugar farm near the coast of Florida applies a nitrogen based fertilizer to their soil three times a year. When rain falls on these fields after it has been fertilized some of the fertilizer runs off into the ocean causing the nitrogen levels in the water to increase. The increase levels of nitrogen can lead to many ecological effects beginning with the rapid growth of algae. This process is known as eutrophication.
How can eutrophication affect other organisms in the water?
Group of answer choices
The algae provide food for fishes and other organisms, leading to decreased algae populations.
The oxygen in the water is used up as algae is decomposed, reducing the amount available to other organisms.
The water becomes better able to support aerobic organisms.
The extra nitrogen provides additional food for the other organisms, increasing their population.
Answers
Answer:
The algae provide food for fishes and other organisms, leading to decreased algae populations
Explanation:
Excessive nutrients lead to algal blooms and low-oxygen (hypoxic) waters that can kill fish and seagrass and reduce essential fish habitats. ... Eutrophication sets off a chain reaction in the ecosystem, starting with an overabundance of algae and plants.

5. A dedicated earth science student using

pressure at the base of Slide Mountain
as 1016.0 mb. At the same time another
dedicated earth science student measures
the pressure at the top of the mountain.
Which pressure reading could be correct
at the top of Slide mountain?
(1) 1016.0 mb (3) 1025.7 mb
(2) 988.5 mb (4) 1040.0 mb 5
Answers
Answer:
(2) 988.5 mb.
Explanation:
The air pressure descends as we ascend. In other words, they are inversely proportional.
The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.
Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
A barometer is an instrument that is designed for measuring the changes in air pressure.
The aneroid barometer has metal chamber as when the air pressure increases the walls of metal push in and when the pressure is low they come out. The chamber is connected by the springs and needle. If the pressure of the base of a mountain is about 1016.0 MB. The pressure of the top of the mountain is 1025.7 MBHence the option 3 is correct.

A-Uranium
B-Plutonium
Answers
Answer:
Uranium
Explanation:
I had it on a quiz
Plutonium is the wasted portion of a nuclear fuel rod which is reused for nuclear weapons. So, the correct option is B.
What is Plutonium?Plutonium-239 is an explosive substance that may be used as nuclear reactor fuel or as a nuclear bomb explosion. It is created from uranium-238 in nuclear reactor fuel rods via a process known as nuclear transmutation. When uranium-238 receives a neutron, it is transformed into plutonium-239, which can fission and release energy.
The plutonium-239 produced in a nuclear reactor is utilized as fuel, together with uranium-235, to continue the nuclear chain reaction. The plutonium-239, on the other hand, may be extracted from spent nuclear fuel and refined for application in nuclear weapons. Nuclear reprocessing is a contentious problem due to the concerns of nuclear proliferation and the possibility for nuclear terrorism.
Therefore, the correct option is B.

What role does meiosis play in gamete formation?Meiosis is a type of cell division that occurs in organisms that reproduce sexually and plays a crucial role in the formation of gametes, which are the cells that are involved in sexual reproduction, during this process, a cell's DNA is replicated, and then the cell divides into four daughter cells, each with half the number of chromosomes as the parent cell and this process is important because it ensures that the gametes produced by an organism will have the correct number of chromosomes, which is necessary for the proper development of the offspring.
Hence, in the meiosis, the upper-most cell is the diploid parent cell; the below image explains the crossing over, and then independent assortment is seen in the order to make two haploid daughter cells at the end of meiosis I, and in meiosis II, four daughter cells will be formed.

haw are living organisms department on the soil?are organisms that live in water totally independent of soil as a resource
Answers
Answer:
Organisms are dependent upon soil. Plants/Producers takes up minerals and water from the soil . ... Organisms living in water are not independent of soil as resource as they also consume food that is made from soil directly or indirectly.
Soil forms an important element for the survival of living organisms. All living organisms, such as microbes, insects, humans and plants rely on soil to live. Animals rely on plant for food. Soil provides anchorage to the roots and for the plants to grow properly. Soil provides a habitat for many microbes and small animals, which in return increases the fertility of the soil by decomposing complex organic compounds.
Organisms that live in water are indirectly dependent on the soil. Some of the aquatic animals depend on the aquatic plants for their food. These plants require certain minerals for their growth. These minerals are carried to water bodies from soil by rivers, rain fall etc. In the absence of these dissolved minerals from the soil to these water bodies, aquatic plant would not be able to grow and thus, affect the aquatic food chain, eventually.
