The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.
Answers
Answer:
According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.
Explanation:
The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.
In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.

Bacterial cells are very small - about 10 times smaller than most plant and animal cells. Most bacterial cells range in size from 0.2 to 10 microns or micrometers (0.0000079 to 0.00039 inches). ... One reason why bacterial cells are so small is that they need a large surface area to cell volume to take in nutrients.

Explain how bacteria can be both harmful and helpful.
Answers
The species of bacteria that colonize our respiratory and digestive systems help set up checks and balances in the immune system. White blood cells police the body, looking for infections, but they also limit the amount of bacteria that grow there. Likewise, bacteria keep white blood cells from using too much force. Bacteria also help out by doing things cells are ill-equipped to do. For instance, bacteria break down carbohydrates (sugars) and toxins, and they help us absorb the fatty acids which cells need to grow. Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don’t get a chance to grow and cause disease.
Some species of bacteria in your body can result in diseases, such as cancer, diabetes, cardiovascular disease, and obesity. Usually, these diseases happen only when the normal microbiome is disrupted, but that can occur even from antibiotics. Antibiotics kill bacteria, and some of those will be good bacteria that we need to protect our health. When that happens, the bad bacteria that normally are kept in check have room to grow, creating an environment ripe for disease.
Bad bacteria can exist at low levels in your body without causing harm or can grow too much and wreak havoc. Staphylococcus aureus can cause something as simple as a pimple or as serious as pneumonia or toxic shock syndrome. P. gingivalis can cause gum disease, and was recently linked to pancreatic cancer (read our article find out more). Similarly, when not suppressed by good bacteria, Klebsiella pneumonia can cause colitis, and subsequently lead to colorectal cancer.
In addition to allowing disease-causing bacteria to flourish, the elimination of good bacteria throws the immune system out of whack. The result can be simple allergies or very debilitating autoimmune diseases. Without the right balance of bacteria, your body might suffer from constant inflammation.
Inflammation is the body’s alarm system, which calls white blood cells to heal a wound or to get rid of infection. Chronic inflammation, however, can make the body more susceptible to autoimmune diseases and cancer, such as causing inflammatory bowel disease which if uncontrolled can cause colon cancer.

Blood vessels are connected to nerve fibers which are regulated by the
nervous system. When innervated they respond by doing what?
Answers
Answer:
When blood vessels are innervated they respond by contracting and relaxing their muscle wall, as a result of the activity of the autonomic nervous system.
Explanation:
The nerves that are responsible for the innervation of the blood vessels are called nervi vasorum, and are composed of nerve fibers of the sympathetic and parasympathetic nervous systems.
The innervation of the blood vessels specifically acts on the muscular wall of the vessel, so it contracts or relaxes depending on the activity of the nervous system:
Sympathetic nervous system stimulates vascular contraction.Parasympathetic nervous system makes the vascular smooth muscle relax.The action of the autonomic nervous system has an effect on blood pressure, being a determinant of normal or pathological behavior of the arteries.

Explanation:
Carbon atoms enter the child as part of organic molecules. These will first be broken into smaller molecules by the process of digestion. These smaller molecules contain the same amount of energy. The child needs oxygen so that his cells can perform cellular respiration. This process transforms chemical energy into energy, carbondioxide gas and water. The carbon atoms leave the body of the child in the form of carbondioxide gas through breathing process..

Place the terms into the correct column that describes the reactions of photosynthesis.
Answers
Answer:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
Explanation:
In the light-dependent reaction, which occurs in the THYLAKOID MEMBRANE of the chloroplast, energy from SUNLIGHT is used to breakdown WATER to release electrons in order to synthesize ATP and NADPH from ADP and NADP+. In a nutshell, the processes involved in this stage are Electron transport chain, photosystem I, photosystem II, and ATP synthase.
- In the light-independent stage, also called CALVIN CYCLE, the ATP, NADPH, and CO2 are used as reactants to synthesize SUGAR (glucose), NADP+ and ADP (which goes back to the first stage) as products.
The light-dependent reactions involve both photosystems I and II along with the electron transport system. ATP is synthesized in this reaction, so ATP synthase is also included.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The light-dependent reaction of photosynthesis occurs in the thylakoid membrane. Sunlight and water are the reactants of this reaction. The products of this reaction are NADPH, ATP, and oxygen.
Light-independent reaction involves the Calvin cycle. It occurs in the stromal part of the chloroplast. The reactants of this reaction are carbon dioxide, ATP, and NADPH while the products are glucose, NADP+, and water.
Therefore, the difference between light-dependent reaction and light-independent reaction is well described above.
