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

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer:
See the attachment.
Hope u understand
In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.
A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.
Let the fixed charge for the first three days be x and the charge for each extra day be y.
From the given information, we can set up two equations:
For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]
For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]
We can solve for x and y by using elimination or substitution:
Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:
[tex]\rm 3x + 4y = 27[/tex]
[tex]\rm - (6x + 4y = 42)[/tex]
Solving above equations, we get:
[tex]\rm -3x = -15[/tex]
[tex]\rm x = 5[/tex]
Substituting x = 5 into one of the equations, we can solve for y:
[tex]\rm 3(5) + 4y = 27[/tex]
[tex]\rm 15 + 4y = 27[/tex]
[tex]\rm 4y = 12[/tex]
[tex]\rm y = 3[/tex]
Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

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

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
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 some cases, people who test positive for genetic testing can receive preventive treatments. For example people who test positive for the breast cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast removal surgery) before they develop the disease. In other cases, no preventive treatments are available, but frequent monitoring can help detect a disease earlier, when it's more easily treated.
What ethical or professional concerns does a health-care professional need to address when he or she has a patient who wants to prematurely treat a genetic disease? Do you think genetic testing should be part of normal preventive healthcare? Why or why not.
Answer:
Yes because genetic testing will provide enough evidice for the genetic disease. If you do so you can find diseases before they have long lasting effects on the hosts body

Which does not provide for enhanced genetic mixing?
A.Mix-matching
B.Random segregation
C.Crossing over
D.Fertilization that occurs through sexual reproduction
Answer:
A. Mix-matching
Explanation:
Sexual reproduction increases genetic variation in offspring by three main mechanisms: 1-random assortment of chromosomes during meiosis 2-genetic recombination, and 3-random fusion of gametes from different parents. In the first place, the pairs of homologous chromosomes are randomly oriented in metaphase I before they separate in Anaphase I. In consequence, daughter gamete cells receive different combinations of chromosomes. Second, recombination (also called crossing over) refers to the interchange of genetic material between non-sister chromatids during prophase I, thereby also increasing genetic variation in daughter cells. Third, the fusion of two haploid cells (i.e., gametes) in diploid organisms results in the formation of a single zygote cell that develops into a new organism, thereby the process of random fertilization between any two gametes generates different diploid zygotes, increasing thus genetic diversity.

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

9. What is the economic importance of beekeeping both in terms of pollinating, crops, and obtaining products from the hive? 10. Explain how the spread of trypanosomiasis can be controlled by releasing male sterile tsetse flies in to an area. Date of submission July 07, 2021 Wednesday
Answer:
9. Bees play a very important role in relation to agricultural production. Indeed beekeeping is a vital part of our agricultural system. Apart from crop plants which are highly dependant on bees, the presence of honey bees also improves the quality and quantity of crops in general.
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. The World Health Organization has targeted West African trypanosomiasis for elimination as a public health problem by 2020.

Answer:
Lignin.
Explanation:
The structural integrity of plant spores is lignin that is present in many parts of the plant. This lignin provides hardness to the plant body which help them to stand the plant erect. If this lignin is not present in the plant body the plant will not stand erected. This lignin is present in large amount in the stem of plant body so that's why the lignin provides structural integrity to plant spores
