Which viral replication cycle is represented in part A of this diagram?
O A. Dormant cycle
OB. Replication cycle
C. Lysogenic cycle
O D. Lytic cycle
Answer:
The correct answer is - option D. lytic cycle.
Explanation:
The lytic cycle is one of the two viral reproduction cycle. Generally, it is the major reproduction cycle. In this cycle reproduction of the viruses takes place inside the host cell and produce more viruses. In the production of the more viruses the host cell and it''s destruction takes place in the end. The 5 steps that takes place are as follows:
1- attachment - viruses attach to the cell.
2-penetration- only nucleic acid or genetic material is injected into the host cell through the hole made by the tail fibers and enzymes.
3- synthesis - replication of viral nucleic acid and protein and envelope.
4- assembly - assembling of the new viruses formed.
5- release.
Thus, the correct answer is - option D.

The lock-and-key analogy is used to describe the Group of answer choices binding of G proteins to transmitter receptors. activation of the nerve impulse. action of transmitter molecules on receptor proteins. degradation of transmitter molecules by enzymes.
Answer:
The correct option is the degradation of the transmitter molecules by enzymes.
Explanation:
The key lock system is a type of enzymatic catalysis / anabolization, and is so called because the enzyme that reacts with its substrate is in the male-female or key lock format.
Enzymes can also react by other mechanisms, but this is known for the perfect fit of the substrate with the binding site, since one represents the negative of the other, once joined and the reaction started, the active site is occupied and the enzyme is not reacts with another substrate simultaneously to that one.

The theory of plate tectonics helps to explain _____.
7. List all the possible different gametes that could be produced from the following parents:
a. Tt
b. GG
с. ff
Answer:
a. Tt - Gametes T and t
b. GG - Gametes G only
с. ff - Gametes f only
Explanation:
Gamete formation or meiosis is a cellular division of the reproductive cells in sexually reproducing organisms. Meiosis produces daughter cells (gametes) with a reduced number of chromosomes (by half) as the parent cell.
According to Gregor Mendel in his law of Segregation, he stated that the alleles of a gene get separated into gametes in such a way that only one allele can be found in the gamete. The separation is random and equal.
Based on this, a heterozygous parent Tt will produce gametes with alleles T and t in an equal proportion. Since parents GG and ff contains the same alleles in their genotype, they will produce gametes with only one type of allele each i.e. Gametes with alleles G and f respectively.

Crop rotation is a method of soil conservation because _______. a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients
Answer:
d. It avoids the depletion of soil nutrients.
Explanation:
Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.
Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.
Thus, the correct answer is option d.

You mix activated yeast with different carbohydrates and measure the CO2 production over a time span of 10 minutes for each type of carbohydrate. Is this experiment a qualitative analysis or a quantitative analysis
Answer:
quantitative analysis
Explanation:
Qualitative analysis refers to quality whereas quatitative analysis refers to the amount or quantity. In this experiment, we see how much carbondioxide gas is produced after the use of different carbohydrates given to the yeast. In this experiment, we want to know the concentration of the product in the reaction not the quality so we can say that this experiment shows quantitative analysis as compared to qualitative analysis.

All materials within ecosystems can be recycled.
Answer:
All the things expect enegry are recycled.
Explanation:
When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled. The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

*Environmental science 11. What’s the main difference between the anthropocentric and the holistic approach to nature? The anthropocentric approach is a subset of the holistic approach. The anthropocentric view places humanity at the center of the universe and considers nature as something to use (and abuse). The holistic approach sees humanity as part of nature and subject to its natural laws The anthropocentric point of view was only commonplace in Medieval Europe because of its religious implications. A holistic point of view is less theistic The anthropocentric view places humanity at the same level as nature while the holistic view places as inferior 12. According to a study by the World bank, what’s the relationship between a country’s economic improvement and environment indicators There’s no relationship between a country’s economic development All environment indicators improve as the country gets richer.

Diverse groups are _____ able to provide for all of their members’ needs and tend to have _____ integration and communication than do homogenous groups. A. more, more B. more, less C. less, more D. less, less
Answer: Option A.
More more
Explanation:
Diverse groups are more able to provide for all of their members needs and tend to have more integration and communication than homogenous groups because they are made of of people who are different from each other and also have distinct characteristics. This is because they are more productive and perform better because they have expertise range of experienceand working methods that can boost problem-solving capacity and lead to greater productivity. They tend to have more integration and communication than homogeneous group because they bring broader ideas and new perspectives to the table and many members will be partaker of the community. This group of people are different from each other and have different perspectives compare to homogeneous group. They provide for their members because of abundance of resources provided .
