What are the possible gametes (sperms) that would be produced from a male carrying balanced translocation between chromosomes 11 and 22, if it occurs in 2:2 Segregation: adjacent segregation
2 ) Fertilization
Fertilization is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm are haploid, which means they each contain one set of chromosomes; upon fertilization, they will combine their genetic material to form a zygote that is diploid, having two sets of chromosomes. A zygote that has more than two sets of chromosomes will not be viable; therefore, to ensure that the offspring has only two sets of chromosomes, only one sperm must fuse with one egg.
In mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. When a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reaction, take place. In placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane. The fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. Fusion between the oocyte plasma membrane and sperm follows and allows the sperm nucleus, centriole, and flagellum, but not the mitochondria, to enter the oocyte. The nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome. This process ultimately leads to the formation of a diploid cell called a zygote. The zygote divides to form a blastocyst and, upon entering the uterus, implants in the endometrium, beginning pregnancy.

Process of fertilization: (a) Fertilization is the process in which sperm and egg fuse to form a zygote. (b) Acrosomal reactions help the sperm degrade the glycoprotein matrix protecting the egg and allow the sperm to transfer its nucleus.
To ensure that no more than one sperm fertilizes the egg, once the acrosomal reactions take place at one location of the egg membrane, the egg releases proteins in other locations to prevent other sperm from fusing with the egg. If this mechanism fails, multiple sperm can fuse with the egg, resulting in polyspermy. The resulting embryo is not genetically viable and dies within a few days.
Cleavage, the Blastula Stage, and Gastrulation
A zygote undergoes rapid cell divisions (cleavage) to form a spherical ball of cells: the blastula; this will further develop into a blastocyst.

Assume that S. typhi immediately enters the bloodstream from the small intestine. Of the following, which would be the first major organ that bloodborne S. typhi would encounter?
A. Stomach.
B. Pancreas.
C. Large intestine.
D. Liver.
Answer:
D. Liver.
Explanation:
Blood from the small intestine is taken to the liver. For this reason, we can state that if S. typhi enters the bloodstream through the small intestine, the first organ it would affect would be the liver.
The liver receives blood from the small intestine to be able to remove all toxins or useless substances from this blood and regulate how the distribution of nutrients contained in the blood will be to other parts of the body.

The answer to this question
Answer:
- Spores occur underneath the leaves - PTERIDOPHYTES
- cones contain the seeds - GYMNOSPERMS
- absorbs nutrients through diffusion and osmosis - BRYOPHYTES
- ovary encases the seeds - ANGIOSPERMS
Explanation:
Plants are a very diverse group of living organisms. Each plant group has its own unique characteristics that distinguishes it from other groups. Bryophytes and pteridophytes are considered as lower plants because of their primitive features while gymnosperms and angiosperms are considered as higher plants because of their advanced features. The prominent characteristics of each plant group according to this question is as follows:
- PTERIDOPHYTES produce spores underneath their leaves.
- BRYOPHYTES absorbs nutrients through diffusion and osmosis since they lack true roots, stems and vascular tissues.
- GYMNOSPERMS bear their naked seeds on structures called cones or strobili.
- ANGIOSPERMS encases their seeds in ovaries of their flowers, which later develops into fruits.

Lucas places 20 kg samples of each substance by the same heat source all samples are at the same initial temperature which sumvstance will have the greatest temperature after some period of time
Answer:
Metallic structure with black colour body.
Explanation:
The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.
Answer:
copper
Explanation:
it copper because it have less specific heat (j/kgoc)

You have a beautiful garden at home. On Sunday, you start budding your rose plant to make few more samples of rose plants to plant in the garden. Can you categorize how this scenario could be represented by classes and instances?
Answer:
It is possible to make this categorization as follows:
Roses = Class
Rose samples = instances
Explanation:
In a very direct and objective way, we can state that classes are models that define how a given situation will be handled, which methods will be used to manage it and the objectives that will be established in that situation. Instances, on the other hand, are elements taken from the interior of classes, which contain factors that make them up. Based on this, we can determine that, in the case of the above question, roses are classes and rose samples are instances.

What is transaction between school and post school destination
Answer:
The transition between school to a post school is a difficult phase in one's life because it opens a lot of adjustments whether it is socially, mentally and/or psychologically. Most students find it difficult to transfer because of these following reasons visit these links and see the answers below: brainly.ph/question/2641856, brainly.ph/question/2635171, brainly.ph/question/2627976
There are a bunch of strangers. Not all students are gifted with an extropersonal skills that allows them to make friends easily. Transition makes it difficult for introvert pupils to accept.
The new school is bigger than their previous school. Though in others the size of a place is not bothering their performance, there are individuals who find it difficult to adjust when it comes to the size of their environment. For example a student who studied in a small private school with only one section will find it difficult to adjust moving around a larger environment.
There are different teaching styles coming from the school's faculty. Learning styles are somewhat define by the teacher's teaching styles and strategies. In their previous school, some of the seniors might have already leaked the strategies used by the teacher in their school. But in a post school, some students are 100% newbie wherein they have no idea what is going on inside a class of a single professor or instructor. This is difficult since they do have to observe every single day and learn a new way to follow the lesson's phase.
Friends are not with the same post school. It is said that you can go through anything with your friends but most of the time you will never be with them when you transfer to a post school but still you need to move forward and learn to mix with the public.
Lessons are difficult and new. Most learners are not accustomed in learning quick in a new environment especially when the lesson is more difficult and new.
New policies are too intimidating to break. Some students are struggling when it comes to adjusting to rules whether it is inside the classroom or just a simple campus rule so they feel intimidated and and fearful in breaking one. But it must be remembered that rules keep the society moving forward peacefully.
Explanation:
There are different reason for an individual to fear and feel difficulty adjusting to a post school. But one must remember that humans are created with an adaptability skill that allows us to mix well with a new habitat and environment. Social skills are just part of our adaptability. You can just follow the wind and let the flow take you. Life is a constant change and all you have to do is to embrace it to make yourself belong anywhere you go.

What is transaction between school and post school destination?The transition between school and post school destination means that the youth is ready for next stage of their lives. The perfect transition of the students from high school to college or the adult world is very important.
