Which 2 organs perform both chemical and mechanical digestion?

Answer:

A further increase in the size of a cell could result in a surface area too small for adequate exchange of materials.: A large surface to volume ratio means that a small amount of living matter has a large surface through which nutrients, oxygen and wastes can diffuse.

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.

Answer:

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 .

Plss follow me and Mark as brainlest

Answer:

Describe the three ways meiosis produces genetic variability. We have seen that meiosis creates variation three ways: crossing over, mutations caused during crossing over, and independent assortment.

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.

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.

Answer:

Lysosomes

Explanation:

Lysosomes also break down old cell parts and release the substances so they can be used again.

Explanation: A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.

Answer:

Osmosis

Explanation:

Osmosis is the diffusion of water or gas molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.

Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell.

The difference in the concentration of a substance between two areas is called the concentration gradient.

Answer:

Isotonic: there would be no net flow of water, the cell will stay stable

Hypotonic: the cell will fill up with water and burst

Hypertonic: The cell will shrink because it loses water

Answer:

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:

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.
