White blood leukocytes cell count is an indicator of health. 4,000 to 11,000 per μL of blood is a normal figure, or 1% of total adult blood volume. Blood cell production is then often regulated by the body structures such as the lymph nodes, spleen, liver, and kidneys.
Leukocytes A type of blood cell made in the bone marrow and found in the blood and lymphatic tissue. White blood cells are the part of the body's the immune system. They are help the body to fight infections and the other illnesses. the Leukocytosis means high white blood cell count. This means that you have more white blood cells than normal.

Consider a tree that is 50 m tall and is transpiring roughly 90 liters of water each day. Approximately how many calories will the tree use to transpire this quantity of water?.
The tree won't spend any calories no matter how much it has to transpire.
Calories are units of energy. They are basically the amount of energy required to raise the temperature of one gram of water by 1 degree Celsius. The question means to ask us how much energy will be spent by the tree.
The tree won't spend any energy in the process of transpiration. The process of transportation in plants is handled by the leaves which transpire water from their surface. This makes it so that the tree doesn't have to do anything which means no energy is spent!

how do the small size and rapid reproduction rate of bacteria contribute to their large population sizes and high genetic variation?
Despite being small, the population is huge. A trillion bacteria can be found in a few handfuls of dirt, making up the population of bacteria there. Bacteria are a few micrometers in size, which is smaller than the size of a sand grain.
Large population size is a result of rapid reproduction. In a short amount of time, the bacterial population grows significantly. Bacteria can multiply in a matter of minutes to a few hours. Their growth is exponential, thus after each replication cycle, there is an increase in their population.
High genetic variation is a result of rapid reproduction rates. After a short while, the bacterial population starts to get more and more mutated. Bacteria must replicate their DNA very quickly in order to maintain their rapid reproduction rate; this causes replication errors that result in mutation. As a result of the replication machinery moving too quickly, mutations accumulate in the genome and cannot be repaired.
Bacteria may prevent growth in areas that are small and "deficient" in nutrients. This characteristic is due to the bacterial cell wall and adaptations rather than the size of the bacteria.

for which codon(s) could a single base change account for this amino acid change? lysine to asparagine
There are two lysine codons (AAA, AAG) and two asparagine codons (AAC, AAU).
A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals). There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
Lysine, or L-lysine, is an essential amino acid, which means it is required for human health but cannot be produced by the body. Lysine must be obtained through diet or supplementation. Protein is made up of amino acids such as lysine.
In humans, asparagine is a non-essential amino acid. It is a beta-amido derivative of aspartic acid and is important in the biosynthesis of glycoproteins and other proteins.

Types of human microbiome include bacteria, archaea, fungi, protists, and viruses. Micro-animals can also live in the human body, but are usually excluded from this definition.
The microbiome consists of beneficial and potentially harmful microbes. Most are symbiotic (benefiting both the human body and the microbiome) and a few are pathogenic (promoting disease). In a healthy body, pathogenic and commensal bacteria readily coexist. Microbiome refers to the group of up to 1,000 different microorganisms or bacteria that live in your body. This bacterium aids digestion, destroys harmful bacteria, and helps control the immune system. The gut microbiome is made up of trillions of bacteria, fungi, and other microbes.

. which of the following is a function of the urinary system? a. filtration of blood b. management of waste products in blood c. temporary storage of urine d. formation of urine e. regulation of blood pressure and volume f. adjustment of plasma ph
Answer:
The functions of the urinary system are:
All of these, a. filtration of blood b. management of waste products in blood c. temporary storage of urine d. formation of urine e. regulation of blood pressure and volume f. adjustment of plasma pH.
Explanation:
Function of the urinary system
The urinary system begins with the kidneys. The smallest unit of the kidney, the nephron, consists of an arteriole, a glomerulus, Bowman's capsule, and a tubule. Blood in the arterioles will enter the glomerular capillaries and be filtered (Function 1: filtration of blood).
Then, it enters Bowman's capsule and tubules. In the tubules, two things occur: reabsorption and secretion. Reabsorption is to reabsorb the filtered material that is still needed by the body from tubules into the arterioles. Meanwhile, the secretion carries out the material that is not filtered and is no longer needed into the tubules (Function 2: management of waste products in the blood).
In the process of reabsorption and secretion, there is regulation of blood pressure and blood volume by the RAAS (Renin-Angiotensin-Aldosterone System). These three enzymes form the system by receiving signals from blood vessels. If there is hypotension (decreased blood pressure) or hypovolemia (reduced blood volume), blood flow to the kidneys will decrease and baroreceptors (blood pressure receptors) in the body will also detect it. Then RAAS will be activated. Activation in hypotension/hypovolemia will result in increased reabsorption of sodium and water, so that it will increase blood pressure (Function 3: regulation of blood pressure and volume).
In addition, reabsorption and secretion processes also occur for blood pH regulation with ions, namely H+ and HCO3- ions. When the blood pH is too acidic, H+ ions will be secreted and HCO3- ions will be reabsorbed. This will make the blood pH remain alkaline (Function 4: adjustment of plasma pH).
After reabsorption and secretion, the products in the tubules will be excreted into urine (Function 5: urine formation).
The urine formed in the tubules unites and exits the kidney through the ureter and is temporarily stored in the bladder (Function 6: temporary storage of urine).

Why do a double circuit heart better than single heart.
A double circulatory system has two loops, one from the heart to the lungs and one from the heart to the rest of the human body. The advantage of a double circulatory system is that blood can be pumped to the rest of the body at a higher pressure than the rate at which it is pumped in a single circulatory system.
The double circulatory system, also defined as the double loop circulatory system, is a type of circulatory system that includes two separate circuits for blood flow that cause blood to pass through the heart twice in the same cycle. This is the type of circulatory system that is present in most mammals. There are two loops of blood vessels in the heart:
The systemic circuit pumps oxygenated blood from the heart to the rest of the body.The pulmonary circuit pumps deoxygenated blood from the heart to the lungs of the human body.Together, the two circuits help to separate oxygenated and deoxygenated blood at the same time. Even though it takes up a little more energy than a single circuit system, it is way more efficient and faster than the single circuit system.

Different combinations of sounds, including grunts, pants, and hoots, are used by chimpanzees to communicate. Chimps communicate with other chimps by making simple gestures like waving their hands in their general direction or reaching out their hands pleadingly for assistance.
They then rely on the other animal's intelligence to assess the situation and respond. Even some chimpanzees learn to create their own unique signals. A "woo" is unmistakably a response to a threat, but panted grunts are typically submissive greetings. A chimpanzee's grunt almost always denotes the presence of food. And a recent study found that chimpanzees can put these sounds together in different ways to create "sentences" that have varied meanings.
