Answer:

Cell membrane encloses all the cell organelles.  In prokaryotes, membrane is absent and so membrane-bound cell organelles are also absent.

Significance of membrane can be explained with the help of viruses, as viruses lack cell membranes and that is why they require a host for living and uses the host's cell machinery to multiply.

Hence, cell membranes are important for living organisms to live and perform essential biological processes.

At eight weeks of development, the fetus has developed all of the following except a fully formed digestive system.

At eight weeks of development, the fetus has developed many important structures and organs. It has a beating heart, a complete central nervous system, and well-defined fingers and toes. It also has some facial features, although they may not be fully formed yet. However, the digestive system is not fully formed at eight weeks.

While the basic structure of the digestive system is present, including the mouth, esophagus, stomach, and intestines, these structures are not yet functional and the fetus is still dependent on the mother's placenta for nutrition. The digestive system will continue to develop and mature over the course of fetal development and after birth.

Answer:

the person likely will eat more than normal, thereby developing obesity and an increased likelihood of suffering heart diseases

Explanation:

The gene (ob) in mice is a homolog of the LEP gene in humans which encodes an adipocyte-specific secreted protein called 'leptin1' that modulates different physiological processes by controlling the hormone Leptin. This hormone (Leptin) is secreted by adipose tissue in order to regulate appetite and hunger. People/mice with a defective version of the leptin/ob gene likely won't control their appetite and will eat more than normal, causing obesity, which is associated with a higher risk of developing cardiovascular diseases (for example, heart attacks).

The process that allows phagocytes and other white blood cells (WBCs) to pass through the walls of small capillary blood vessels allowing them to reach the damaged tissue is called diapedesis.

Diapedesis is the migration of WBCs from the bloodstream to the damaged tissues. It occurs when WBCs squeeze between the cells lining the small blood vessels called capillaries. White blood cells use diapedesis to combat infections, cancerous cells, and other potentially harmful materials in the body.

When the body detects tissue damage, it sends white blood cells to the area to attack foreign bodies, bacteria, and other harmful agents that may have caused the damage. When the white blood cells have completed their mission, they are removed from the body via the lymphatic system.

When C3 is first released into the blood, the status of the thioester bond is that it is highly reactive and undergoes rapid hydrolysis.

The complement component 3, or C3, is a protein in the human body. The protein is an essential component of the immune system's complement system, which is a complex series of proteins that work together to help the immune system recognize and destroy invading pathogens. C3 performs a variety of functions in the complement system, including being a key component of the C3 convertase, which is a protein complex that cleaves C3 into two fragments.

The thioester bond is a critical feature of C3, and it is what makes C3 so reactive and essential to the immune response. When C3 is first released into the bloodstream, the thioester bond is highly reactive and undergoes rapid hydrolysis. This means that the bond is quickly broken down into its constituent parts, which limits the protein's ability to participate in the immune response. In conclusion, when C3 is first released into the blood, the status of the thioester bond is highly reactive and undergoes rapid hydrolysis.

The chance of having a child with light skin and light hair would be zero in this case.

There is a 50% chance that you have medium skin and wavy hair, and a 25% chance that you have dark skin and curly hair.

If we treat race as a Mendelian trait that shows complete dominance, the woman who is homozygous dominant for dark skin and curly hair would have the genotype DDCC, and the man who is homozygous recessive for light skin and straight hair would have the genotype ddcc. The dominant alleles (D and C) would mask the expression of the recessive alleles (d and c), and all their offspring would be heterozygous for both traits, with the genotype DdCc and the phenotype of dark skin and curly hair.

Assuming that the gene for skin color and hair type shows incomplete dominance, the heterozygous offspring (DdCc) would have a phenotype that is a blend of the two homozygous phenotypes, with medium skin color and wavy hair. If the heterozygous offspring (DdCc) mate with each other, the offspring would have a 25% chance of having light skin and straight hair, a 50% chance of having medium skin color and wavy hair, and a 25% chance of having dark skin and curly hair.

The sharp increase in water temperature due to global warming drives  zooxanthellae death. Corals lose their symbiotic algae and suffer  bleaching due to the lack of photosynthetic organisms that provide them with color.

Corals are naturally translucid or white organisms. However, they look brightly colored because they host symbionts with colorful photosynthetic pigments.

Corals can host different organisms that live on and among them, giving place to amazing ecosystems.  

The photosynthetic unicellular microalgae zooxanthellae are symbionts to the coral.

This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as tropical clear waters.

When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.

Global warming increases water temperature significantly, which makes the bond between algae and coral break because of algae death. The lack of algae means an increase in coral bleaching since there are no photosynthetic organisms that provide them with color. Besides, the absence of algae means no availability of photosynthetic products.

Option B is right. The acceptable control range for hemoglobin is ± 2 standard deviations from the mean, which would be 14.0 ± 0.40 (2 x 0.20). This means the allowable limits for the control are 13.6-14.4, so the correct answer is B.

To find the allowable limits for the control of hemoglobin, we need to calculate the range within ± 2 standard deviations from the mean.
The mean for hemoglobin is 14.0, and the standard deviation is 0.20.
Step 1: Multiply the standard deviation by 2.
0.20 * 2 = 0.40
Step 2: Add and subtract the result from the mean.
14.0 + 0.40 = 14.4
14.0 - 0.40 = 13.6
So, the allowable limits for the control are 13.6 to 14.4.

The given types of securities may be quoted on the OTC Bulletin Board except D) Corporate bonds.

The OTC Bulletin Board (OTCBB) is a quotation service that displays real-time quotes, last sale prices, and volume information for securities that are not listed on national stock exchanges. It is a popular platform for investors to trade and invest in stocks that are not listed on major exchanges like the NYSE or NASDAQ.

When it comes to the types of securities that can be quoted on the OTCBB, most domestic stocks, direct participation programs, American Depositary Receipts (ADRs), and corporate bonds can be quoted. However, one of these types of securities is an exception to this rule.

The answer to this question is D) Corporate bonds. While most securities can be quoted on the OTCBB, corporate bonds are not typically listed on this platform. This is because corporate bonds are usually traded in the over-the-counter (OTC) market, which is a decentralized market that is not subject to the same regulations as national stock exchanges.

Overall, the OTCBB is a valuable platform for investors looking to invest in securities that are not listed on major exchanges. While corporate bonds may not be quoted on this platform, investors can still access them through other means, such as through a broker or dealer in the OTC market.
