What is RhoGAM? How does it work?
Answer:
RhoGAM is a medicine that stops your blood from making antibodies that attack Rh-positive blood cells. RhoGAM is a sterilized solution made from human blood that contains a very small amount of Rh-positive proteins. These proteins keep your immune system from making permanent antibodies to Rh-positive blood.
Answer:
Rhogam is human antibody to the Rh antigen. If any fetal blood cells escape into the maternal circulation, Rhogam binds to the Rh antigen and makes it “invisible” to the mother’s immune system. One dose at 28 weeks, and another at the time of delivery is enough to prevent the mother becoming sensitized.

If two roan cattle were crossed, what percent of the offspring would you expect to have a roan coat? Fill in the blank text field 1
Answer:
50%
Explanation:
I just did the question
If two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.
A heterozygous individual is an organism that carries out two different alleles for the same gene locus.In this case, the 'roan' coat color is observed in heterozygous individuals (genotype R1R2).In consequence, the cross between two heterozygous individuals will produce a progeny in a 1:2:1 proportion.In conclusion, if two roan cattle were crossed, then 50% percent of the offspring are expected to have a roan coat color.

haw are living organisms department on the soil?are organisms that live in water totally independent of soil as a resource
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.

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.
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.

The blood types that are possible for a child whose parents both have AB blood type is A, B, and AB. The correct option is B. I, II, and III.
What are the blood types?Blood types are the different types of blood groups that are different in different organisms. The different blood types are A, B, AB, and O. The blood groups are important to know because only the same blood group can be transferred to another human if they needed blood.
If the parents are of the AB blood group, then the offspring will have only chances of having A, B, or Ab blood group.
Thus, the correct option is B. I, II, and III regarding possible blood type for children whose parents both have AB blood type.

what types of cells are made by meiosis
Answer:
Meiotic cells
Explanation:
Answer:
The cells made by meiosis genetically differ from the ones made by mitosis. When a cell is created by meiosis, the cell's chromosomes are greatly reduced thus producing four Gamete cells. Gamete cells are reproductive cells and are used either as sperm or egg cells.
(Chromosomes: A thread-like structure of DNA (nucleic acids and proteins) that carries genes.

This is an onion root tip at low power (100x). The cells are too small to distinguish individual phases. What phase do most of the cells appear to be in?
Answer:
Interphase
Explanation:
The phase in which most of the cells appear to be in is interphase.
This is so because cell's life is spent more in interphase and in this phase growth of cells and at the end their replication takes place. So cells get more time in interphase to grow and replicate, which makes more cells to appear to be in.
Hence, the correct answer is "Interphase".

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.

5. A dedicated earth science student using
an aneroid barometer measures the air
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
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.

what are 3 parts of the blastocyst .
Answer:
outer trophectoderm layer (TE. trophoblast), an inner cell mass (ICM, embryo blast) and a blastocoel (fluid filled cavity)
The blastocyst is distinguished by the blastocoel, trophoblast cells, and inner cell mass.
What is blastocyst?A blastocyst is composed of an inner group of cells surrounded by an outer shell. The embryo will be formed by the inner group of cells.
Stage 3 begins when a cavity appears in the morula and ends when the embryo makes contact with the endometrial lining of the uterus and the zona pellucida is shed. Free blastocysts are stage 3 embryos.
Day 3 embryos are called "cleavage stage" embryos. The reason for this certification is that the embryo's cells are dividing (or cleaving), but the embryo is not growing in size.
The blastocoel, trophoblast cells, and inner cell mass distinguish the blastocyst.
Thus, these are the 3 parts of the blastocyst.
