Answer:

Your body uses water in all its cells, organs, and tissues to help regulate temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.

Answer:

Water is needed for your digestive track as it digests foods. As water is also needed for each cell to properly function in your body.

Answer:

Small uncharged polar molecules, such as H2O, also can diffuse through membranes, but larger uncharged polar molecules, such as glucose, cannot. Charged molecules, such as ions, are unable to diffuse through a phospholipid bilayer regardless of size; even H+ ions cannot cross a lipid bilayer by free diffusion.

Answer:

C

Explanation:

The karyotype shown in the question is characteristic of Down syndrome, also known as Trisomy 21. Therefore option A is correct.

Down syndrome is a genetic disorder caused by the presence of an extra copy of chromosome 21, resulting in a total of 47 chromosomes instead of the typical 46.

The karyotype reveals three copies of chromosome 21, indicated as 47,XY,+21, which is indicative of Down syndrome in a male individual.

People with Down syndrome may experience developmental delays, intellectual disabilities, and characteristic physical features, such as almond-shaped eyes and a flat facial profile.

The presence of an extra chromosome 21 is the defining genetic abnormality in individuals with Down syndrome.

Therefore option A is correct.

The answers is B

Explanation:

I just took a test that had this question on it.

B. contact with an infected person

Transmission occurs when an infected person interacts or exchanges bodily fluids with another person.  This can happen before the infected individual even realizes they are sick.

After a weekend field trip to the aquarium with their classmates, five pupils catch a cold. Because they may have come into contact with an infectious person, students became ill. Students became sick as a result of B. contact with an infected person

Answer:

Somatic mutations are mutations that occur in body cells, that is the cells that do not make gametes. These mutations are not passed on to further generations; for example, if a mutation that changes a gene in a skin cell would not affect your children because skin cells don't produce gametes.

Explanation:

The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information. Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid).

Answer:

Magnification In general terms, it can be said that how big or small the image appears with respect to the object is called magnification of the object.

Explanation:

It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter 'm'.

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

A cisterna refers to a flattened membrane disk that makes up the Golgi apparatus. A typical Golgi has multiple stacks of anywhere from 3 to 7 cisternae stacked upon each other like dinner plates.The cisternae also carry structural proteins important for their maintenance as flattened membranes and their stacking upon each other.

Answer: try B

Explanation:

As a cell's size increases, the amount of DNA stays the same. The information used to build the molecules needed for cell growth is in the DNA. If a cell grows too large, an "information crisis" would occur.

Answer:

Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes . Meiosis also produces genetic variation by way of the process of recombination .

Explanation: Meiosis is important for three main reasons : it allows sexual reproduction of diploid organisms , it enables genetic diversity , and it aids the repair of genetic defects .

Note:

In the attached files you will find the image of the three insects

Answer:

(i) Because they share the same genera, Vespula.

(ii) Because Morphologically, insects 1 and 2 are more alike than insect 3.

Explanation:

(i) Explain how the binomial names indicate that insects 1 and 2 are more closely related.

In taxonomy, many categories are used to aggregate organisms according to their evolutive relationship. These are Domain, Kindom, Clase, Order, Family, Genera, Species, Subspecies. All species might be recognized by their common name and their scientific name, which is more reliable. The binomial names of living beings indicate the scientific name by which the organisms can be recognized. A species scientific name is composed of two parts:

- Generic name or genera: correspond to many species that share common characteristics. In the example, Vespula is the genera

- Specific epithet: useful to identify each species in particular and differentiate organisms that are included in the same superior taxes. In the example, flavopilosa and rufa are the epithets that differentiate one species from the other.

According to this, we might assume that species 1 and 2 are more closely related because they share the same genera: Vespula. This suggests that they share more characteristics in common with each other than with Callicera.

(ii) Explain how the appearance of the three insects suggests that insects 1 and 2 are more closely related.

Morphologically, insects 1 and 2 are more alike than insect 3. Traits such as body shape, pigmentation pattern, antenna, wings, total body size, among others, are very similar in species 1 and 2. On contrary, species 3 is smaller, with a thinner antenna, different pigmentation patterns, different wings size and shape.

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Answer:

Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds.  The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.
