Answer: 1. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive. 2. The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. A bacteriophage, or bacteria virus, injects its DNA into the bacteria. ... The DNA is then replicated when the bacteria undergo cell division. 3. A lysogenic virus can remain inactive for a period of time. In lysogenic infection, viral DNA gets integrated with the host cell's DNA, where it is copied along with the host cell's DNA when the host cell replicates. ... It then removes itself from the host cell's DNA and enters the lytic cycle. The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse). 4. So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms. brainliest?
Explanation:
Trace minerals are needed in much smaller amounts than major minerals, but they are just as essential for good health.
a. True
b. False
Answer:
The correct answer is - true.
Explanation:
Like macromolecules and vitamins, minerals are also essential for a healthy body. The essential minerals can be divided on the basis of their requirement into major minerals and trace minerals.
The trace elements and the major elements both are equally important. It does not matter if a high amount of major elements are required and a small amount of trace elements required. The amount is not an indication of the importance of the element.

Explanation:
In mitosis, the DNA is replicated once, while in meiosis it is replicated twice.
True or False?
Answer:
False
Explanation:
Like mitosis, meiosis is a form of eukaryotic cell division. However, these two processes distribute genetic material among the resulting daughter cells in very different ways. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
You are given a constitutive mutant, but you are not told whether it is constitutive due to a repressor mutation (i-) or an operator mutation (oc). Determine what could be added to the system that would allow you to determine the difference between the two mutants. You will add the same thing to each and indicate the results of the experiment.
Answer:
Explanation:
Repressor molecules, as we recognize them to be proteins occur as transcription factors that may function on their binding sites within the same genome or even on a different genome.
As a result, repressor molecules behave in a trans-active manner. Operator, on the other hand, acts as a binding site mostly on the chromosome genome which can only trigger downstream genes. As a result, Operators are cis-acting.
In this scenario, if we give the system a Plasmid containing a wild-type repressor gene, the repressor molecules would only attach to the usual Operator sites.
In the 1st scenario:
The Operator is regular and normal, but I- is mutated. As a consequence, the additional extra plasmid's normal repressor molecules will stick to the operator site, causing suppression or repressed expression.
In the 2nd scenario: genome
The repressor is natural, but Oc is mutated. As a consequence, the additional extra plasmid's normal repressor molecules would not adhere to the operator region, resulting in the same Constitutive expression.

Explain why mining has such a large impact on the environment.
Answer:
Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.
Answer: I agree with the above answer
How many chromosomes are made by using a cell "c"
Answer:
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females.

Does mutation decrease or increase genetic variation
Answer:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation
Floods, droughts, fires, and earthquakes are examples of
Answer:
Floods, hurricanes, tsunamis, earthquakes, volcanic eruptions, forest fires, famine, and droughts are examples of natural disasters, which have adverse effects on countries. In my opinion, I like to see the term “natural disaster” as a word human beings use to blame nature for their lack of environmental sustenance.
I answered the same question before So I went to the answer and copied it.
28. Which of the following statements about hormones is incorrect? a) Glands that produce them are ductless glands. b) They are produced only by organs called endocrine organs. c) Some are water soluble and some are not. d) They often maintain steady-state conditions. e) They may turn genes off or on
Answer:
b) They are produced only by organs called endocrine organs.
Explanation:
Hypothalamus can be defined as a small portion of the mammalian brain responsible for the secretion of hormones through the stimulation of the pituitary gland.
It is located between the midbrain and the thalamus. Also, hypothalamus is the most inferior portion in the diencephalon of the forebrain.
Basically, hypothalamus is the most important portion of the brain in vertebrates that controls various bodily functions.
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
The following statements about hormones are correct;
I. Glands saddled with the responsibility of producing hormones are ductless glands i.e directly secreting hormones into the bloodstream.
II. Hormones are either soluble in water or insoluble in water.
III. Hormones are often responsible for maintaining steady-state conditions in the body of a living organism through homeostasis.
IV. Hormones are typically able to turn genes off or on.

Which flock will be able to eat the most? The least? Why?
Answer: The omnivorous flock will eat the most as it eats both insects and seeds. With the removal of fruit it will not be affected much. The herbivorous flock will eat the least as it has the option to eat seeds only after the removal of fruit. The flocks all started with 10 birds. Flock was X the most successful at feeding, so it will have the greatest number in the second generation. brainliest?

F. What is the phenotype of a plant with the genotype RW?
What is the most abundant plant hormone and where is it found in the plant?
Answer:
Indole-3 acetic acid
Explanation:
IAA causes cell wall extension by activating the proton pump, which keeps the cell wall acidic at a pH of around 4. The cell wall pressure is reduced in these conditions, and water enters the cell, resulting in an increase in cell volume. As the cell grows in size, new cell wall material is required to keep the wall stable. Auxin IAA is a naturally occurring substance. It also promotes cell enlargements, cell division in the vascular cambium, root initiation enlargement, cell division in VA.
IAA can be found in the seeds of many plants, especially legumes like peas and broad beans.
