What is the name of lipids building blocks?
Answer:
Glycerol and fatty acids are the basic building blocks of fats (lipids).
Explanation:
Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse
In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae
Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.Learn more about this topic here:

Muscle weakness is associated with Vit A/ Vit E/ Vit K/ Protein deficiency
Answer:
Low vitamin E levels may result in Muscle weakness: for the central nervous system, vitamin E is vital. It is one of the major antioxidants in the body and a shortage causes oxidative stress that can lead to weakening in muscles.
Explanation:
The body needs to work with vitamin E and become a necessary vitamin. It is fat-soluble, thus it has to be effectively absorbed in fat from the food. Before being released to the bloodstream for usage, vitamin E is mostly kept in the liver.
The deficiency is unusual and usually caused by an understatement. There are also modest levels of preterm newborns.
Eight kinds of vitamins exist. A blood test allows a physician to know how much a person has of an alpha-tocopherol form. Use this information to establish if the total vitamin E level of a person is present.
A standard level is typically between 5.5 and 17 milligrams (mg/L) per litre. For premature infants and youngsters under 17 years, the typical range may be different. The Normal scope may also be somewhat different amongst laboratories.
If an adult has less than 4 mg/L of vitamin E in his or her blood, supplementation is usually necessary.
The locus B on the X chromosome of a malaria-carrying mosquito shows a 49% recombination rate with respect to the locus M. Since a recombination rate of 50% is essentially indistinguishable from independent assortment, you might be tempted to look for a locus that falls between B and M. Before you decide to do all that work, you run a chi square test to determine the P value of your experiment.
Required:
What range of P values would tell you that you should accept the conclusion that locus B and locus M are, indeed, 49mu apart and that another locus is not necessary?
Answer:
The correct answer is - P = 0.45
Explanation:
The Chi-square test is a test that determines the assorted genes independently. Here p-values used to make conclusions in significance testing.
If the p value is less than the significance level we expect or choose, then this null hypothesis is rejected in favor of the alternative hypothesis. It p value is greater than or equal to the significance level, then we fail to reject the null hypothesis.
So in this case, as the recombination rate is 49% so the p value which satisfies the conclusion will be around 0.45 and values near to it.

Answer:
b.) Sensor - Integrator - Effector
Explanation:
During homeostasis, our body sense change that occur in the external environment through sensors. These sensors sends the information to integrator or the control center where the information is analyzed. After analysis, the instructions are send to the effectors to take action against the change which is occur in the external environment of our body so the correct order of homeostasis is Sensor - Integrator - Effector.
Which of the following statements about eutrophication is TRUE?
a) Eutrophic bodies of water are characterized by clear water that is relatively free of algae. •
b) Climate change is expected to worsen eutrophication because many phytoplankton grow better in warm water
c) Eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation
d) Eutrophication can harm fish and other aquatic species but does not cause health problems for humans
Answer:
c) eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation.eutrophication happens when too much nitrogen enriches the soil, causing excess growth of plants and algea.
I hope this helps
When nitrogen from fertilizers seeps into soil, it frequently fosters weed growth rather than the development of native plants. The excess of nutrients caused by nitrogen washing into streams is known as eutrophication. Thus, option C is correct.
What best define about eutrophication?A surplus of nutrients in water, primarily nitrogen and phosphorus, causes a process called eutrophication. By consuming the nutrients, algae flourish, proliferate, and tint the water green.
Algae blooms can have an unpleasant odor, restrict sunlight, and in some circumstances even produce toxins.
The process of eutrophication occurs when a body of water receives an excessive amount of nutrients, which increases the growth of algae and macrophytes. It causes water bodies' dissolved oxygen levels to drop and their water quality to deteriorate.
Therefore, Eutrophication is typically driven by natural processes like rock weathering and nitrogen fixation.

During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?
Answer:
During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol
Explanation:
During the conversion of glucose to pyruvate, NAD+ is converted into NADH.
What is alcoholic fermentation?Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.
The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.
Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.

Question Mode Fill in the Blank Question Fill in the blank question. In cells that contain a nucleus, the DNA is divided into multiple linear chromosomes which are organized into a complex structure called
Answer:
The correct answer is - chromatin.
Explanation:
Chromatin is a part within a chromosome consisting of DNA and protein. The DNA carries the cell's genetic instructions and these are complex structures present in multiple linear chromosomes.
The major proteins in chromatin are histones, which help package the DNA in a compact form that fits in the cell nucleus.
The nucleus of the cell is similar to the_______ system of the body.
The nucleus of the cell is similar to the Neurological system of the body.
What is Nucleus?According to the Cell Biology, nucleus may be a membrane found in organism cells.
The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.
Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.
The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell
The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".
The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.
The nucleus is the largest organelle in animal cells.
For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
What is Neurological System or Nervous System of the body?The Nervous system could be a extremely advanced a part of associate degree animal that coordinates its actions and sensory data by sending signals to and from completely different components of its body.
In vertebrates it consists of 2 main components, the central system (CNS) and therefore the peripheral system (PNS). The CNS consists of the brain and neural structure.
The function of the system is to send signals from one cell to others, or from one a part of the body to others and to manage the body.
It will this by extracting data from the setting exploitation sensory receptors, causing signals that encrypt this data into the central system, process the data to work out associate degree applicable response, and causing output signals to muscles or glands to activate the response.
