Tay-Sachs also affects 1 in 30 individuals with French-Canadian ancestry then in this condition , 1 in 2 will get the disease that is there is 50% possibility.
What type of disease is discussed in the question ?It is an autosomal recessive disorder.
The chances where the two two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent is 25 % that is the child will not have any disease.
The chance where the child inherits a mutated one from one parent and becomes a carrier, but will not have the condition themselves. 1 in 4 (25%) chance that means the child inherits a faulty gene from both parents and develops Tay-Sachs disease.

This is ur answer.....
Poorly developed nervous and muscular systems – because parasites live inside their hosts, they don't need eyes, ears or a keen sense of smell to detect potential predators nor a brain to facilitate escape. They have little need for a muscular system because they have no place to go.

Carol and Sam were using the microscope in science class. They used a dropper to put some pond water on their microscope slide. This is what they saw. "That is something living," said Sam. "I don't think so," said Carol. What do you think? Explain.
options:
This is not alive. It is not moving or responding.
This sample is made of identical units. It is not alive.
This is a multicellular organism made of cells. It is living.
This may have been alive once, but not now because it is not moving.
Answer:
Sam was actually correct. Pond water usually contains microrganisms like bacteria, viruses, and parasites. This is also why people do not drink pond water without getting rid of the impurities.

What is cell cycle?
Cell cycle is defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one is G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step is G2 phase in which cell ready to divide.
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
Therefore, Robert Hooke was the first person to observe cells. He observed these cells in a piece of cork. Thus, option A is correct.

how can the h. pylori bacteria survive in the human stomach?
Answer:

helper t cells secrete ________ to stimulate the proliferation of b cells.
Answer:
Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.
Helper T cells secrete cytokines to stimulate the proliferation of B cells.
What are Helper T- Cells?Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.
Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.
They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

State 2 of Newtans three laws
(PLS HELP ASAP!!)
1. Something at rest or in motion in all constants will remain that way unless acted upon by a force.
2. F=ma
Explanation:
Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
Force equals mass times acceleration; it states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
what is the importance of predation in an ecosystem
Answer:
Without predatation, things wouldn't eat each other.
Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...
If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)
It's a food chain. A CHAIN. Each varible depends on each other.
And a food chain has a direct impact on the ecosystem.
For example:
No rabbits mean there is so many grass and carrots left behind
No wolves means there are too many rabbits
So that means
No wolves
Whatever eats the wolves wont be alive
Whatever eats THAT wouldn't be alive
after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.
Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.
One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.
However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.
The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.

Answer plz!
Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks
Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
