Explain why chemogenetic based methods of regulating cellular signaling result in poor temporal control of biochemical pathways relative to optogenetic based methods.
Answers
Answer:
They use different detecting methods to assess neuronal circuits
Explanation:
Chemogenetics is a technique widely used in neuroscience research to explore signaling interactions by means of genetically modified receptors capable of interacting with small molecules. Chemogenetics was first used to determine the function of the chalcone isomerase gene by inducing mutations that altered its substrate specificity. On the other hand, optogenetics is a bioluminescence-driven genetic technique used to control genetically modified neurons that express light-gated ion channel genes. This technique is also used to monitor neuronal networks. In consequence, optogenetic and chemogenetic techniques have recently been combined in order to analyze neuronal circuits, it by analyzing the same actuator molecule.

The uterine cycle describes the cyclic changes of thickening and degeneration that the endometrium goes through in a month. What is the order of events in one uterine cycle
Answers
Answer:
During the uterine month there are different phases through which the uterus passes, these phases are regulated by hormones and are responsible for producing the cycle necessary for fertilization.
Phase where menstruation occurs: This phase only happens if the woman was not fertilized and did not develop the diploid cell together with a sperm, since not being fertilized, all the uterine preparation that had been planned in the body for fertilization will be released as that we know "menstruation", in this phase estrogens and progesterone are low. The inner walls of the unfertilized uterus are released.
Follicular phase, in the follicular phase the ovaries prepare to release an egg and estrogen begins to rise. (From the first day of the period until ovulation)
Proliferative phase, in the proliferative phase, new vessels proliferate and the outermost layer of the uterus prepares itself for possible fertilization, is where spiral arterioles can begin to form again in the external cut of the myometrium.
Ovulation, here is where the mature ovum is called Graff's follicle, at this time estrogen reaches its peak and then descends.
Luteal phase, in the luteal phase the production of the luteal body is generated, at this stage progesterone takes center stage, and it is the range between ovulation and menstruation (if not fertilized)
Last phase, secret phase, in this phase there are two possible ends, if the woman is fertilized, the egg cell implants and begins the development of the embryo and if it is not fertilized, the entire external cut of the myometrium is prepared to be secreted.
Explanation:
A very important fact to clarify is that women are born with a quantity of ovules that at the end of this uterine cycle ceases to exist, this process is what we know as menopause.
That is to say that women have a quantity of ovules that will one day run out, and the body releases them from the menarche or the first menstruation, generating that in each released ovule a uterine cycle is completed, the day they end the woman will have reached menopause and would have no chance of being fertilized or completing the uterine cycle.

Cellular Respiration: C₆H₁₂O₆ + 6O₂ ----> 6CO₂ + 6H₂O + ATP
What is cellular respiration?Cellular respiration is a process of converting food into energy that can be used in many processes. It happens when oxygen is combined with food material and releases carbon dioxide as a waste product.
The correct reaction of photosynthesis is when carbon dioxide and water are combined with sunlight to form glucose and oxygen.
The correct reaction of cellular respiration is when glucose and oxygen react and release carbon dioxide and water and energy,
Thus, the correct reactions are:

Answers
Answer:
The sequence is TCAA
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two complementary chains of nucleotides. The nucleotides are in turn composed of one nitrogenous base, one deoxyribose sugar, and one phosphate group. The four different types of nitrogen bases found in DNA are thymine (substituted by Uracil during RNA transcription), adenine, cytosine and guanine. These bases bind by complementary base pairing to form an antiparallel double-strand. The complementary base pairing rule states that thymine forms two hydrogen bonds with adenine, while cytosine forms three hydrogen bonds with guanine.

Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and/or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one may be from each group.)
Answers
Answer:
a. Angiosperm are plants (autotrophs) that use photosynthesis to produce their own food, while vertebrates are animals (heterotrophs) that obtain their food from other organisms. Vertebrates include fish, amphibians, reptiles, mammals and birds.
b. Adaptations in angiosperms include two reproductive structures 1- fruits (ovaries), whose main function is to disperse the seeds and 2- flowers that ensure pollination and protect the embryo sac during its formation.
c . Examples:
1- The mycorrhizal symbiosis between plant roots and symbiotic fungi plays a key role in nutrient uptake from the soil. Arbuscular mycorrhizal is a type of symbiosis where a fungus of the phylum Glomeromycota penetrates the cortical root cells of vascular plants to produce specialized structures named arbuscules.
2- Microflora in the vertebrate digestive tract. The microorganisms that live in the digestive tract of vertebrate species are beneficial for the absorption of nutrients. For example, in humans, Saccharomyces boulardii has shown to have a probiotic effect by increasing intestinal homeostasis, thereby enhancing nutrient uptake.

Why were the advent of metagenomics, and the application of molecular techniques such as single-cell and next-generation sequencing, important for defining a microbial relationship
Answers
Answer:
Based on novel approaches, it has been seen that symbiotic associations prevails between a host and one to thousands of more microbes, which challenges the previous meaning of symbiotic association as one that takes place between the host and a single microbe. It was considered previously that symbiotic association’s takes place only between the pair of single microbe and host.
However, newer approaches has revealed that such kind of association can take place between one microbe and many other hosts. A symbiotic association can take place between microbe-microbe, plants-plants, microbe-plants, and others. However, symbiotic association has never been found to take place between a bacteria and animal host. The symbiotic associations are always not parasitic.

Hemoglobin is the blood protein responsible for the transport of oxygen. Carbon monoxide disturbs oxygen transport by
Answers
Answer:
Answered below
Explanation:
Hemoglobin is found in the red blood cells and is responsible for the transportation of oxygen from the lungs to the various body cells.
Oxygen binds to hemoglobin because it has a high affinity for it. This aids its transportation. When it gets to the cells it unbinds and get transported into the cell for use in energy production.
Carbon monoxide is an odourless, dangerous gas which has more affinity for hemoglobin than oxygen. Therefore when carbon monoxide is inhaled, it quickly binds to hemoglobin, thereby displacing oxygen. It binds to hemoglobin for a longer period and due to this, the body does not get any oxygen and cells begin to die.
Symptoms of carbon monoxide poisoning include dizziness, headaches, fatigue and coma.
