Name two types of fluids
found
in female reproductive
Organs
Answer:
A female's internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a muscular, hollow tube that extends from the vaginal opening to the uterus. Because it has muscular walls, the vagina can expand and contract.
Explanation:
Welcome!
Answer:
The oviduct and uterus provide the environments for the earliest stages of mammalian embryo development. However, little is known about the mechanisms that underlie the formation of oviduct and uterine fluids, or the extent to which the supply of nutrients via these reproductive tract tissues matches the nutrient requirements of early embryos. After reviewing our limited knowledge of these phenomena, a new experimental paradigm is proposed in which the epithelia lining the endosalpinx and endometrium are seen as the final components in a supply line that links maternal diet at one end and embryo uptake of nutrients at the other. When considered in this way, the oviduct and uterine epithelia become, for a few days, potentially the most critical maternal tissues in the establishment of a healthy pregnancy. In fulfilling this 'gatekeeper' role, female reproductive tract fluids have a key role in the 'developmental origins of health and disease' concept.

A diagnostic test for tuberculosis (TB) involves injecting antigen (from the bacterium that causes TB) under the skin and then waiting a few days for a reaction to appear. This test is NOT useful for diagnosing TB in AIDS patients. Explain why
Answer:
This test is called TB Skin Test.
Some people who are infected with both HIV and TB bacteria will not react to the TB skin test. This is because the immune system is not working properly. Anyone who is HIV infected and has a negative skin test should also have other medical tests, if they have symptoms of TB disease.

Most nerves of one of the sense organs go to the spinal cord before they go to the brain. Which organ is
this? (Think of your own body.)
Answer:
Umm every sense of organs travels in the spinal cord.
Most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain..
What is the significance of the reflex action?Reflex actions are important because they allow the body to respond quickly to stimuli without waiting for the brain, and they can be especially important in situations where a quick response is necessary to avoid danger, such as when the hand touches hot substances and the hand suddenly goes back, which is due to the motor neuron action of the spinal cord.
Hence, most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain.

Examine the model of the carbon cycle select all of the processes that we turn carbon compounds to the atmosphere.
The processes that considerably turn carbon compounds into the atmosphere are the decaying of organisms, the respiration of animals, and emissions from automobiles and factories. Thus, the correct options for this question are B, C, and E.
What do you mean by the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbo and its derivative products are exchanged among the various spheres of the earth's surface. Carbon is considered one of the main components of biological systems.
In the carbon cycle, rhe process of photosynthesis utilizes the carbon from the atmosphere in order to produce chemical energy in the form of glucose. While the excretion of animal waste products is responsible for nitrogenous compounds like urea or ammonia.
Except for these two, all other options are directly liberating carbon into the atmosphere which can easily be demonstrated in the carbon cycle.
Therefore, the correct options for this question are B, C, and E.

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein
(2) Synthesis of phosphatidylcholine
(3) Degradation of misfolded ER protein
(4) O-linked glycosylation
Answer:
EELG
(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum
(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum
(3) Degradation of misfolded ER protein ossurs in the Lysosome
(4) O-linked glycosylation occurs in the Golgiapparatus
Explanation:
1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.
N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.
The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.
2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.
Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).
The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.
3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.
4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.
describe the structure of an atom of argon-38 and argon-40
Answer:
Argon 38 has 18 proton and 20 neutron
Argon 40 has 18 proton and 22 neutron
Explanation:
isotope is same no of proton diff no of neutron
Both argon-38 and argon-40 have 18 protons but they have different atomic masses. The atomic mass of argon-38 is 38u while the atomic mass of argon-40 is 40u. Thus, they are isotopes.
What are isotopes? Some atoms contain the same number of protons (i.e. same atomic number) but they have a different number of neutrons (i.e. different mass numbers). These types of atoms are called isotopes.Argon element has three isotopes namely, argon-36, argon-38 and argon-40. All the three isotopes of argon have the same number of protons i.e. 18. But, all have different numbers of neutrons and thus, different mass numbers. Argon-36 has 18 neutrons, argon-38 has 20 neutrons and argon-40 has 22 neutrons. Thus, the mass numbers of argon-36, argon-38 and argon-40 are 36u, 38u and 40u respectively.Thus, the structure of an atom of argon-38 and argon-40 is slightly different as they are isotopes. Argon 40 has more atomic mass than argon-38. But, both contain the same number of protons. They have similar chemical properties but different physical properties.

write a 5-7 sentence paragraph explaining what happens to co2 levels in the world over the course of the year. add as much context and details as you can
Answer:
The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
Explanation:
Opposite of cellular respiration
Answer:
On a simplified level, photosynthesis and cellular respiration are opposite reactions of each other. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
Answer: Photosynthesis
Explanation: Cell respiration and photosynthesis are essentially opposite processes. Photosynthesis is the process by which organisms make high-energy compounds – the sugar glucose in particular – through the chemical "reduction" of carbon dioxide (CO2).
