Explanation:
what happens to the concentration of oestrogen at ovulation?
Answers
Answer:
When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle). The follicle becomes the corpus luteum and this produces oestrogen and progesterone which inhibit FSH and LH production by the pituitary.

What can be inferred about the osmosis of water in potato cells?
A. The cells stop gaining water by osmosis in the 0.2M solution, so the concentration of glucose in the potato cells must be greater than 0.2M.
B. The cells stop gaining water by osmosis in the 0.2M solution, so the concentration of glucose in the potato cells must be between 0.1M and 0.2M.
C. In the solutions where the cells lose water by osmosis, the original concentration of water in those cells must be less than the concentration of water in the solutions.
D. In the solutions where the cells gain water by osmosis, the original concentration of water in those cells must be greater than the concentration of water in the solutions.

Answers
Answer:
Germ
Explanation:
i learned about them
The types of cells which are found n the reproductive organs of humans are known as germ cells.
Which types of cell divisions are performed by germ cells?The types of cell divisions that are performed by germ cells are known as meiosis and mitosis. Meiosis is a type of cell division through which produces four haploid daughter cells that are not identical to their parents.
Germ cells are responsible for the production of gametes. This involves the differentiation of germ cells in order to produce male and female gametes. These cells are sometimes known as immortal because they are thought be assemble a linkage between generations.
Somatic cells are those cells that are responsible for the building blocks of the entire body. These somatic cells are only divided by mitosis.
Therefore, germ cells are the types of cells that are found in the reproductive organs.

ATP - P --- ADP provides the chemical energy for most cell functions.
What do you mean by chemical energy ?The bonds of chemical molecules contain energy. Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
The energy in meals is transformed into energy that the body's cells can utilise during cellular respiration.
A new substance may form and energy may be released when the molecules of chemical substances react chemically.
Energy is transferred to ATP during cellular respiration, which transforms glucose and oxygen into carbon dioxide and water.

It takes 83 mL of a 0.45 M NaOH solution to neutralize 235 mL of an HCI solution. What is the concentration of an HCI solution?
Answers
Answer:
168ml
Explanation:
It takes 83 mL of a 0.45 M NaOH solution to neutralize 235 mL of an HCI solution, than the concentration of HCl will be 0.158 mL.
What is concentration?The amount of a chemical substance in a mixture is expressed by the substance's concentration.
What is neutralize?
The interaction of H+ ions with OH- ions produces water in a neutralization reaction, which occurs whenever an acid as well as a base reacts to form water and salt.
Calculation of concentration.
Given data:
[tex]V_{1}[/tex] = 83 mL
[tex]C_{1}[/tex]= 0.45 M
[tex]V_{2}[/tex] = 235 mL
[tex]C_{2}[/tex] = ?
Concentration of HCl solution will be calculated by using the solution.
[tex]C_{1} V_{1} = C_{2} V_{2}[/tex]
where, C is concentration and V is volume.
Put the value of given data in above equation.
[tex]C_{2} =C_{1} V_{1} / V_{2}[/tex]
[tex]C_{2}[/tex] = (0.45 M)(83 mL) / 235 mL
[tex]C_{2}[/tex] = 0.158 mL.
Therefore, the concentration of HCl will be 0.158 mL.

a triple bond and a double bond
Answers
A triple bond and a single bond is the bond which a single carbon atom can have and is denoted as option C.
What is Bond?This is referred to as the attraction which exists between atoms and are involved in the formation of substances in a chemical reaction.
Carbon on the other hand is am element with an atomic number of 6 and has four valence electrons present in its outermost shell. This means it needs four electrons to achieve a stable configuration which is why a single atom must have a total of four bonds which is a triple bond and a single bond, two double bonds etc.

Define embryonic stem cells. Explain the pros and cons of Embryonic Stem Cells
Answers
Answer:
Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.
Explanation:
Adult Stem Cells
Embryonic Stem Cells
Induced Pluripotent Stem Cells
Pros
Trans differentiate and and reprogramming of these cells is possible but is not well studied
Thought to be less likely to be rejected if used in transplants
Success has already been demonstrated in various clinical applications
Can maintain and grow for 1 year or more in culture
Established protocols for maintenance in culture
ESCs are pluripotent cells that can generate most cell types
By studying ESCs, more can be learned about the process of development
Abundant somatic cells of donor can be used
Issues of histocompatibility with donor/recipient transplants can be avoided
Very useful for drug development and developmental studies
Information learned from the “reprogramming” process may be transferable for in vivo therapies to reprogram damaged or diseased cells/tissues
Cons
Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.
Cannot be grown for long periods of time in culture
Usually a very small number in each tissue making them difficult to find and purify
Currently there is no technology available to generate large quantities of stem cells in culture
Process to generate ESC lines is inefficient
Unsure whether they would be rejected if used in transplants.
Therapies using ESC avenues are largely new and much more research and testing is needed
If used directly from the ESC undifferentiated culture prep for tissue transplants, they can cause tumors (teratomas) or cancer development
Methods for ensured reproducibility and maintenance, as differentiated tissues are not certain.
Viruses are currently used to introduce embryonic genes and has been shown to cause cancers in mouse studies
All living things are made of one or more cells, and those cells are either eukaryotic or prokaryotic. You, like all animals as well as plants and fungi, have eukaryotic cells. That means your cells have a nucleus. Inside that nucleus, genetic material (DNA) is coiled into thread-like chromosomes. Organisms with eukaryotic cells are called eukaryotes. Prokaryotic cells, on the other hand, are more simple. They lack specialized, membrane-bound organelles, like mitochondria, and they do not have a nucleus. Their genetic material is usually in a loop that floats in the cytoplasm. That loop is called the nucleoid. Prokaryotic cells are much smaller than eukaryotic cells. All bacteria are unicellular, made of just one cell, and they are prokaryotes. Some bacteria have flagella, tail-like structures on the end that help them to move.
How are bacteria cells different from human cells?
A
Bacteria cells do not contain a cytoplasm.
B
Bacteria cells do not contain genetic material.
C
Bacteria cells are much bigger than human cells.
D
