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".
How does meiosis create four daughter cells from one parent cell?
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. ... The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
Explanation:
Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell
drag and drop grey to the area
Answer:
The top left is the diploid parent cell
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.

6. Asparagine and Methionine are what type of molecule?
Answer:
Asparagine is the amide of aspartic acid. The amide group does not carry a formal charge under any biologically relevant pH conditions. The amide is rather easily hydrolyzed, converting asparagine to aspartic acid. This process is thought to be one of the factors related to the molecular basis of aging.
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.

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.

O A. Only
OB. I,II, and I
C. I and II
D. III and IV
Answer:
Two parents with AB blood type can have a child with the possible blood types of A, B, and AB.
Explanation:
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.

Birds have air sacs and lungs. When birds
breathe (in / out,) oxygen-rich air fills the
lungs and air sacs. When birds breathe
(in / out), the oxygen-poor air leaves the
lungs, and stored fresh air enters the lungs from
the air sacs. This means that birds always have a
supply of oxygen-(rich / poor) air.

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.

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.
