Microorganisms are classified as bacteria, fungi, protozoa and algae. Viruses are
not explicitly categorized as microorganisms. Give reason.

Answers

Answer:

Yes

Explanation:

Because they have both living and non living characteristics so it is hard to classify them as they posses living characteristics as reproduction and others when inside the host and posses non living characteristics when outside the host

In microorganisms micro means small and organism means living ones, so those living ones which are not seen without the help of a microscope, are microorganism.

What are viruses?

Viruses are obligate parasites and are very small in size. Viruses cannot live outside the host cells as they require host cell gene expression machinery to divide and perform metabolic reactions. Viruses remain inactive in the environment until found the host cells.

As viruses cannot qualify the criteria of living beings because they cannot survive separately in the evnironment,  that's why cannot be considered living organisms.

Mostly microorganisms are single-celled organisms like bacteria, fungi, and protozoa. Viruses are not considered microorganisms because they are nonliving outside the host body.

10. Use insect repellent. Permethrin-impregnated clothing and insect repellent have not been proved to be particularly effective against tsetse flies, but they will prevent other insect bites that can cause illness.

Asexual reproduction differs from sexual reproduction in that Group of answer choices asexual reproduction utilizes DNA from two parents to code for traits in offspring. asexual reproduction occurs only in plants. asexual reproduction produces offspring containing DNA from only one parent. asexual reproduction only occurs in animals. asexual reproduction produces genetically diverse offspring.

Answers

Answer:

Asexual reproduction produces offspring containing DNA from only one parent.

Explanation:

Asexual reproduction produces offspring containing DNA from only one parent because in asexual reproduction, the organisms born or produced from a single parent. The offspring is identical to their parent and this process of asexual reproduction occurs in both plants and animals. Asexual reproduction produces identical not genetically diverse offspring in the end of the process.

Answer:

Because asexual reproduction results in the birth or creation of organisms from a single parent, the children created have DNA from just one parent. Both plants and animals can reproduce asexually, and the progeny are identical to their parents. Asexual reproduction ultimately results in identical, not genetically different, offspring.

When Adenosine Triphosphate is used, it breaks down into:
A. Glucose
B. It doesn't break down
C. Thymine Triphosphate
D. Adenosine Diphosphate

Answers

Answer:

D. Adenosine DIPHOSPHATE

Explanation:

ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy

When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.

Adenosine diphosphate (ADP)

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.

At each ______ foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the ______.

Answers

Answer:

At each intervertebral foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the spinal nerves.

Explanation:

The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs.  In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.

For young men of age 20, there have been 150 rounds of DNA replication during sperm production as compared to only 23 rounds for a woman of age 20. That is a 6.5-fold greater number of cell divisions and proportionately greater opportunity for new point mutations. Yet, on average, 20-year-old men contribute only about twice as many new point mutations to their offspring as do women. How can you explain this discrepancy

Answers

Answer:

A plausible hypothesis is that deleterious germline mutations in sperm cells are removed by natural selection since sperms have to compete to fertilize the egg

Explanation:

Sperm cells need to travel through the cervix in order to reach the uterus and fertilize the egg. During this process (which is called 'fertilization'), approximately 300 million sperm cells have to compete in a race to reach an egg. During fertilization, the majority of sperm cells die off quickly because male germinal cells carry mutations that lead to abnormalities (e.g., many sperms have double heads, others no tail, etc). The sperm cells are considered to be physiologically weak because their normal functions can be easily disrupted by mutations and, simultaneously, they are under strong selective pressure to be selected during the sperm race. In consequence, deleterious germline male mutations are expected to be eliminated by natural selection, thereby sperms are selected before fertilization so only the strongest ones can compete in the race to fuse with the egg cell and thus develop one zygote.

In addition to their security duties, the agents were responsible for having the households vehicles washed and fueled, making wake-up calls, moving furniture, and doing research on the Internet. Schultz's long-time driver and travel agent, Sammy Hebri, formed a company called Capital International Security, Inc. (CIS). Hebri started CIS for the purpose of becoming Schultz's security contractor. Hebri sent a memo (dated July 24, 2002) to the agents directing them to obtain their own private security business licenses from the VDCJS and individual liability insurance so they could be classified as independent contractors.
