Decide whether each statement about urine formation is true or false.
The liver changes toxic substances into less toxic substances that then travel to the
kidneys.
The kidneys filter blood and produce urine.
Urine is made from the nutrients that are reabsorbed back into the blood from the tubules.
The kidney is the functional unit of the nephron.
Urine is produced in the nephrons of the kidneys.
Urine that is produced in the kidneys flows down the urethra to the bladder for storage and
then is excreted through the ureters.

Intro

Answer/Explanation:

The cell cycle consists of interphase and mitosis (M). Within interphase, there are three phases: G1, S, and G2.

G1 phase - the first 'gap' phase.The cell grows in size, and synthesises the necessary mRNA and proteins required to divide.  This is also where the key decision as to whether the cell will divide takes place. This is based on whether or not the environmental conditions are favourable for division and whether the cell is receiving the correct signals to divide. This is called the G1/S transition, and is the critical decision making point as to whether the cell cycle will progress.

S phase - the 'synthesis' phase. The cell replicates its DNA in preparation for passing the genetic material onto the daughter cells. Once the cell's DNA is replicated, it enters G2.

G2 phase - the second 'gap' phase. The cell continues to grow in size and prepare for mitosis. There is a DNA damage checkpoint here, where the cell ensures that the DNA has properly replicated. Next, it moves into mitosis (M).

M phase - the mitosis phase. This consists of 4 stages (PMAT) - prophase, metaphase, anaphase, telophase. The cytoplasm divides during cytokinesis

Answer:

The question is incomplete, below is the completed question:

Medical researchers often test medicines on patients who have given informed consent for the tests. The researchers divide the patients into two groups. One group is given the medicine. The second group is given a harmless substitute such as sugar pills. Neither the patients nor the researchers know which patients have received the medicine and which have received the substitute.  What is the purpose of such a procedure?

to increase accuracy

to increase precision

to decrease bias

to decrease patient safety

Answer:

The correct answer is:

to decrease bias

Explanation:

This kind of experimental setup where a group of participant is given a non-medical treatment is known as a double-blinded placebo experiment. The principle of the use of a placebo is to reduce biases. Biases are influences that may affect the result of an experiment that does not arise from the effect of the treatment itself, but from some external factor. The researcher and the subject do not know which treatment is a 'sham', and which treatment is the real treatment, it helps to make approach neutral and rules out any effect of manipulations that may affect the result as a result of such knowledge.

Answer:

to decrease bias

Answer:

TACCGG

Explanation:

Recall that in DNA, there are two pairs, A goes with T and G goes with C, therefore the complimentary strand for ATGGCC is TACCGG.

Answer:

Answer:Most of the steps of cellular respiration take place in the mitochondria.

Oxygen and glucose are both reactants in the process of cellular respiration.

The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Heterotrophs Meaning:

A heterotroph is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are primary, secondary and tertiary consumers, but not producers.

Answer:

[tex]\boxed {\tt B. \ Using \ grocery \ bags \ only \ once \ before \ disposing \ of \ them}[/tex]

Explanation:

Let's analyze the answer choices. Remember we are looking for an unsustainable option.

A. Renewable energy is a great sustainable practice because it doesn't produce waste.

B. Using grocery bags once is not sustainable. Single use plastic is not good for the environment because it is used one time and then thrown out.

C. Energy efficient appliances are sustainable. They don't consume as much energy.

D. Recycling is always an environmentally friendly option. It allows some materials to be used again.

The choice that is not sustainable is B. using grocery bags only once before disposing of them.

Answer:

cell membrane

Explanation:

Answer:

d. These mutations most likely change the shape of the active site of the enzyme.

Explanation:

A competitive inhibitor competes with an enzyme substrate for the binding of the enzyme. When it binds, the enzyme substrate cannot bind unless the inhibitor is removed from the active site by some mechanism.

The ability of a competitive inhibitor of an enzyme to function is due to the fact that these inhibitors are structurally similar to the enzyme's substrate.

So when a mutation which also affects the activity occurs in a microbe, that renders it resistant to a drug serving as a competitive inhibitor of that enzyme in the microbe, most likely, this resistance is due to a structural change in the enzyme which changes the shape of the enzyme's active site. Therefore, both the drug as well as the enzyme's substrate, will be unable to bind to the enzymes active site.

Answer:

M phase

Explanation:

During the first phase, the cell grows and prepares for DNA replication, which occurs in the subsequent s phase. Further growth takes place in the G2 phase, and finally mitosis occurs in the M phase.

10 units of energy because in food chain the energy is lost and this energy loss is 90% at each trophic level so only 10% of energy is passed soo if grass has 10000 energy units mouse will have 1000, snake will have 100 and then hawk will have only 10 units

Answer:

Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.

Examples-Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago.

Coming of age, a very young person's transition from childhood to adulthood. Age of majority, the threshold of adulthood as it is conceptualized (and recognized or declared) in law. Puberty, the process of physical changes by which a child's body matures into an adult body capable of sexual reproduction.

Explanation:

Answer: The age of maturity refers to the change from childhood to adulthood.

Explanation: This means that a child is taking its first step into being an adult. Usually, this first happens during the process of puberty. Puberty occurs when you’re around 12 years of age. This is when your body starts to change into a more stronger, mature adult body.
