The ability of an ecosystem to support life declines sharply after a population crash
among some of the organisms. A population crash among organisms with which
characteristic could have caused the sharpest decline?
A hibernation during the winter
B mobility on land and in the air
C conversion of sunlight into food energy
D different fur coloring in summer and winter
Answer:
c
Explanation: all other traits are irrelevant and could reply to any part o the food chain, c means that the plats have dropped, meaning that the things that eat the plants wot be able to eat the plants, (primary consumers)and the secondary consumers wont be able to eat the primary consumers,then the tertiary consumers wont be able to eat the secondary consumers. In simpler terms it would cause a chain reaction that would detonate the whole foodchain.

6. Compare the DNA of an offspring to the DNA of its parents.
Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).
The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.
How does the DNA of parents compare to that of offspring?In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.
During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.
Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

The genetic code was elucidated through the use of polyribonucleotide's synthesized either enzymatically or chemically in the laboratory. Given what we now know about the genetic code, how would you make a polyribonucleotide that could serve as an mRNA coding predominantly for may Phe residues and a small number of Leu and Ser residues?
What other amino acid(s) would be encoded by this polyribonucleotide, but in smaller amounts?
Answer:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the serine and lysine residue in a small amount.
EXPLANATION:
The genetic codes are responsible for coding the amino acids. The messenger RNA (ribonucleic acid) consists of triplet codons, which is responsible for the synthesis of respective amino acid sequences. The formation of the RNA stand is done by using ADP, GDP, CDP, and UDP (adenosine, guanosine, cytosine, and uridine diphosphate). It requires no template for the formation of polymers. Therefore incorporation of UDP is done by the incorporation of polynucleotide phosphorylase, which will result in the formation of poly U. The UUU codes for the phenylalanine amino acids. Similarly, the incorporation of 5 mixtures such as ADP, GDP, CDP, and UDP can alternatively produce the mRNA polymer with the ser and lysine residue in a small amount. For example in the stretch of polynucleotide UUU presence of one of the following codon UUA, UUG, CUU, CUC, CUA, CUG as well as UCU, UCC, UCA, UCG, and AGU can synthesize leucine and serine residues. (UUC)n can synthesize the polymer of phenylalanine, serine, and incorporation of few A and G will synthesize leucine. However, the presence of A, C, and G can also synthesize a small amount of tyrosine, isoleucine, and cysteine residue.

The two elements, in looking at their atoms, have a total of 51 protons between them are Magnesium and Aluminum and Lithium and Scandium so option d. both A and B.
What are protons?
The protons are + charges particles found in the nucleus of the atoms.
NO. of protons in :
Magnesium and Aluminum- Magnesium has total of 12 proton and Aluminum has 13 total protons. Lithium and Scandium- Lithium has 3 and Scandium has 21So total no. of protons= 12+13+3+21= 50.
Thus it lies in between total of 51 protons in the periodic table.

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.
Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

D

©2021 Illuminate Education Inc.
Answer:
hmm
Explanation:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :
Use only alternative energies for the production of electricityCarbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.To know more about carbon emission here
