Its called bioamplification
Answer:
Dampak negatif manusia terhadap lingkungan adalah:
Kelebihan penduduk, polusi, pembakaran bahan bakar fosil, dan penggundulan hutan. Perubahan seperti ini telah memicu perubahan iklim, erosi tanah, kualitas udara yang buruk, dan air yang tidak dapat diminum.
Dampak positif manusia terhadap lingkungan adalah:
Melindungi spesies yang terancam punah dan membersihkan danau dan laut memiliki efek positif terhadap lingkungan. Di rumah, Anda dapat membantu planet ini dengan mendaur ulang limbah dan menanam tanaman atau sayuran.
The color that the new generation's offspring show will be red, pink, and white.
The young creation of living things is called an offspring, which can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
All of the pink-flowered progeny are produced when a red-flowered plant and a white-flowered plant are crossed. This cross serves as an example of the incomplete dominance of red and white. The mixing of both alleles results in this circumstance. Gene interaction known as incomplete dominance occurs when only one of two alleles of a gene at a locus is fully expressed, frequently leading to an intermediate or distinct phenotype. Additionally called partial dominance.
CRCW × CRCW = CRCR, CRCW, CWCW i.e, red, pink, and white.
The complete question is:
A red carnation is crossed with a white carnation: Neither one is 3 Fonts dominate over the other: This means that when crossed, their offspring can show pink flower The parent generation genotypes are: CR CR and CW CW (RED x WHITE) An offspring showing pink flowers (CR CW) from the parent generation is now being bred with another pink flower (CR CW) What color will this new generation's offspring show?

Answer:
The correct order is 3, 4, 2 and 1.
Explanation:
Atherosclerosis refers to the condition in which the plaque gets accumulate within the blood vessels' walls. In the condition, inflammation occurs in the arteries' inner lining. The following is the sequence of events that results in atherosclerosis is:
1. A huge concentration of LDL cholesterol gets gathered within the inner walls of the arteries.
2. This causes discharging of macrophages to the site.
3. The engorgement of WBCs takes place with fatty deposits.
4. The hardening of plaques takes place, which eventually prevents the flow of blood in the prime arteries.
1. The correct answer is: The viral envelope proteins interact with CD4 and a co-receptor on the cell membrane.
Binding and entering the host cell are the first steps of the HIV virus infection. So, these steps play a major role in determining the ability of HIV to degrade the human immune system. Binding of HIV to CD4+ T lymphocytes (express chemokine receptors CCR5 and CXCR4 called co-receptors) triggers the fusion of the viral and host cell membranes, initiating infection (viral core gets into the cytoplasm).
Attachment of the virion can be:
• Nonspecific-envelop protein of the virus (Env) binds to cell-surface heparan sulfate proteoglycans
• Specific-Env binds to integrin.
2. The correct answer is: Activation of the host cell by cytokines, growth factors, or antigens.
After the viral capsid enters the cell, single-stranded RNA genome is released from the attached viral proteins and copied it into a complementary DNA (cDNA) molecule thanks to an enzyme called reverse transcriptase. Next step is the integration of the viral DNA into the host cell's genome. This process is done by another viral enzyme called integrase. The integrated DNA is transcribed into RNA and then translated into proteins that will help the package of new viruse particles.
3. The answer is: false
Reverse transcriptase is an enzyme that catalyzes the formation of DNA from an RNA template. Since the genome of the virus (HIV) is single stranded RNA, reverse transcriptase copies it into a complementary DNA (cDNA) molecule. Thanks to this enzyme, formed cDNA can be integrated into host’s genome. Because of this proprety, antiretroviral drugs used to treat HIV infection work as reverse-transcriptase inhibitors.
