What are Lipids?Lipids are defined as a broad group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others. Important functions of lipids include storing energy, signaling and serving as structural components of cell membranes.
A lipid is a type of organic compound that is insoluble in water that includes fats, waxes, oils, hormones, and some components of membranes and serves as energy-storing molecules and chemical messengers.
When we arrange the elution on the basis of charge, triglyceride and cholesterol have no charge placed on first and second respectively, while sphingosine has 1 charge. and phosphatidyl serine and sphingomyelin have more than 2 charges
Thus, the lipids in order of elution by placing the first lipid to elute at the top are as follows:
1. triglyceride
2. cholesterol
3. sphingosine
5. phosphatidyl serine
4. sphingomyelin

Based on the body structures of these animals, which two conclusions are scientifically sound?
Bassa
dog
gorilla
chimpanzee
frog
0 The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
The dog and frog share a closer evolutionary ancestry than the gorilla and chimpanzee.
The dog is more closely related to the frog than it is to the chimpanzee.
All four organisms share a common vertebrate ancestor.
Answer:
(A) The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
Explanation:
The vertebrate and many of the other parts of the skeletal structure of the gorilla and chimpanzee are alike. (and, by using a little background knowledge, you can figure this out by thinking; if humans share 98% of DNA with chimpanzees and about 96% of DNA with gorillas, then the two animals must share a lot of DNA as well.)
I hope this helps !!!
Answer:
1, 3, 4
Explanation:
The gorilla and the chimpanzee have very similar anatomy, so they are closely related.
There is a small resemblance between the dog and the frog, but nowhere close to the one shared with the gorilla and chimpanzee, so NO
the dog IS more closely related to the frog than the chimpanzee since it looks more similar
yes, all of them are vertebrates and therefore share a single vertebrate ancestor

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0
2 19 0.2248 15.7
23 7 0.1331 9.3
SUM: 70 1.0000 70.0
What are the calculated and critical values for this test?
a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.
Answer:
d. calculated = 3.10; critical = 7.815.
Explanation:
To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :
The test statistic is defined as :
χ² = Σ(Observed - Expected)² / Expected
Observed = number of nests
χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)
χ² = 3.1089
The critical value :
df = n - 1 = 4 - 1 = 3
The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

The toxins responsible for botulism are proteins that inhibit the release of acetylcholine, which in turn can cause muscle paralysis. In extreme cases the paralysis can involve the respiratory muscles, and people can die of respiratory failure. This mechanisms of action indicates that the toxins are
Answer:
Poisonous substance.
Explanation:
This mechanisms of action indicates that the toxins are the poisonous substance which attacks on the respiratory system of the body that leads to the respiratory failure. Acetylcholine is the main neurotransmitter of the parasympathetic nervous system which is the part of the autonomic nervous system that contracts smooth muscles so inhibition of the release of Acetylcholine is the main cause of paralysis.
Eukaryotes are different than Prokaryotes, because only eukaryotes have:
A. DNA
B. Capsule
C. Organelles
D. Plasma membrane
Answer:
D
Explanation:
Have a nice day
Eukaryotes are different from prokaryotes because only eukaryotes have Organelles. The correct option is C.
What are prokaryotes?Prokaryotes are primitive organism that is single-celled and their cell contains a capsule and flagella or cilia for locomotion and finding food. These organisms lack true organelles.
Eukaryotes are organisms that can be single-celled or multi-celled. They contain the true nucleus and organelle in the cell and the cell is covered with a cell membrane and a nucleus is present that contains the DNA or the organism.
Prokaryotic and eukaryotic cells, both contain DNA, a plasma membrane. But in prokaryotes, an organelle is absent, and they are covered by a capsule.
Thus, the correct option is C. Organelles.

The Cell-mediated response is a chain reaction of antigens and Interleukins that results in:
A. The swelling of fluid and clotting elements to a damaged area.
B. The differentiation of helper T cells into cytotoxic T cells to destroy pathogens.
C. The production of macrophages to use phagocytosis on pathogens.
D. The differentiation of effector B cells into plasma cells to make antibodies.
The Cell-mediated response results in the production of macrophages to use phagocytosis on pathogens. The correct option is C.
Cell mediated immune response occurs when an invading antigen causes the release of cytokines (Interleukins), differentiation of T cells and production of macrophages.
Macrophages are produced through the differenciation of monocytes. They are further activated during an infection through the macrophage-activating cytokine (Interleukins).
Phagocytosis is the process used by immune cells such as macrophages which involves ingesting and eliminating pathogenic microorganisms.
Cell-mediated response dosent result to differenciation of helper T cells into cytotoxic T cells rather it leads to the activation of cytotoxic T cells. Therefore B is wrong.
Cell-mediated response dosen't lead to the production of antibodies therefore option D is wrong.

What are the features of Nuclear Receptor Screening Services?
Nuclear receptors (NRs) are a class of proteins responsible for thyroid hormones and sensing steroid and certain other molecules. There are 48 genes in the human genome that code for the NRs. As the largest family of eukaryotic transcription factors, NRs control numerous processes involved in development, cell cycle, and important metabolic pathways.
https://dda.creative-bioarray.com/nuclear-receptor-screening.html
Answer:
The nuclear receptor superfamily comprises a large group of transcription factors that play a key regulatory role in development and homeostasis of multicellular organisms. A special feature of nuclear receptors is their ability to bind to condensed chromatin templates, which makes them important initiators of gene transcription. Moreover, the ability of nuclear receptors to sequentially recruit a variety of transcription factors and coregulators to target promoters and to orchestrate the whole process of gene transcription confirms their biological significance and stimulates intensive research and a high level of scientific interest in this field. In this review, we summarise current knowledge regarding the structure and function of nuclear receptors as principal regulators of gene expression. Emphasis is given to the molecular mechanisms of nuclear receptor-mediated transcriptional activation and repression including recent progress made in this area.

B. continuous variables may be restricted to positive values
C. continuous variables will never be nonzero
D. continuous variables must always be restricted to positive values
Answer:
I think it's A
must lie btn a clearly defined interval
Continues variable must be between a clearly defined the interval about continuous variables. Thus,option A is correct.
What is continuous variables?A continuous variables is define as a function which continuous varies in a given interval for instance, if a variable over a non-empty range of the real numbers is continuous, then it can take on any value in that range.
Types of continuous variables:
There are two types of continuous variables which are mentioned below:-
1:- Instant variable
2:- Ratio variable
Instant variable
A variable can be defined as the distance or level which are varies between given interval.
Ratio variable
Ratio variable is another type of continuous variables which has only one variation in given interval.
Therefore, continues variable must be between a clearly defined the interval about continuous variables. Thus, option A is correct.
