The biotic potential can go above the graph, but only for a limited period of time.

What is the biotic potential?

Biotic potential is the maximum reproductive rate of a population when there are no limiting factors such as resources, space, or competition. This rate is determined by the species' fertility, survival rates, and longevity. It is an important concept for population ecology because it can provide a measure of how quickly a population could theoretically grow, given ideal conditions.However, if the environment changes or the resources become scarce, the population size will decrease. Therefore, if the biotic potential goes above the graph, it is likely to be a temporary increase that will not be sustained in the long run.

What do you mean by Population?
Population is a term used to refer to the total number of people, animals, or other living organisms in a given area. It can be used to describe the size of a city, country, continent, or the world. Population can also refer to the total number of individuals in a specific group, such as a species or ethnic group.

Explanation: I believe it is, C. Fr; elements on opposite corners of the periodic table share the same characteristics.

Because it makes for sense

The element that is similar to neon is Ar; elements in the same family of the periodic table share the same characteristics. Option A

The periodic table has to do with the arrangement of the elements in such a way that there can be a systematization of the properties of the elements. We know that elements are said to be in the same group if they do have the same properties.

The elements that are in the same group with neon are the elements argon, krypton. These elements would have the same properties and they would tend to behave in a similar way.

c because animal cells requires no wall to make tissue

plants need chloroplast to survive

Answer:

C.) Cell A is a plant cell; Cell B is an animal cell.

Explanation:

The two cells each have a nucleus and mitochondria, indicating they are eukaryotic cells.

The presence of chloroplast and a cell wall indicate that Cell A is a plant cell, as animal cells do not contain those structures.

Cell B is likely an animal cell because it has a nucleus, mitochondria, and no cell wall.

Do Eukaryotic Cells have Mitochondria?

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

What is a  Eukaryotic cell?

A eukaryotic cell is one of two different types of cells. Organisms that are based on the eukaryotic cell are called “eukaryotes” and include plants, animals, fungi, and protists.

What is Mitochondria?

The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell. Each cell can have from one to thousands of mitochondria. Mitochondria also contain extranuclear DNA that encodes a number of rRNAs, tRNAs, and proteins.

DNA is a polymer composed of several nucleotides. Genes are the inheritable subunits that carry genetic information and are composed of a varying number of nucleotides. D) It packages all the genes in a living thing.

DNA is the deoxyribonucleic acid. It carries all the genetic information needed for the organism to accomplish its functions.

This polymer is composed of several monomers known as nucleotides, which joined by their extremes compose the DNA linear molecule.

Genes are DNA fragments that transmit the information needed to specify traits and are inheritable. These fragments are transmitted as units from generation to generation.

Genes are located in the DNA molecule and are composed of varying numbers of nucleotides.

During the cell cycle, when DNA is lax, it is called chromatin. But when cell division occurs and DNA condensates it forms the chromosomes.

Pedro and Denise were sharing a snack. Pedro drank some hot tea while Denise drank ice water: (B) The molecules in the ice water move slower than in the hot tea.

The molecules in hot and cold water are the same. Each molecule consists of one oxygen atom and two hydrogen atoms. The difference is the rate at which the molecules bounce about.

Because they contain energy, molecules are continually moving. Water molecules travel faster and are literally bouncing off one another when they are in a liquid state as opposed to a solid state. The quantity of potential energy in the liquid decreases as it cools, and the molecules begin to move more slowly.

Option (B) is the correct answer.

When conducting an experiment, the researcher needs to define the variables involved in that experiment. These are the followings,

In this type of experiment, we can talk about a controlled experiment (1D) because the researcher is not just observing, but also controls all the variables to analyze the interaction between the ones of interest.

Once the variables are identified, the researcher can make the hypothesis.

In the exposed experiment about fish breaths we can see how temperature affects the breathing rate. As temperature increases, the breathing rate increases as well.

2A) Independen variable: Temperature. The researcher increases temperature and observes the rate at which its gills open. So the researcher records how the breathing rate responds to changes in temperature.

2B) Dependen variable: Breathing rate. It is affected by temperature. Its change is directly proportional to temperature changes.

2C) The increase in temperature causes an increase in the breathing rate.  

2D) Controlled variables might be, for instance,

2E) If temperature increases even more, the brething rate will keep increasing. However, fishes are very sensitive to temperature changes, so eventually they would be so affected that their breathing rate would decrease.

Answer:

During pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. Since the fetus doesn’t breathe air, his or her blood circulates differently than it does after birth:

The placenta is the organ that develops and implants in the mother's womb (uterus) during pregnancy. The unborn baby is connected to the placenta by the umbilical cord.

All the necessary nutrition, oxygen, and life support from the mother’s blood goes through the placenta and to the baby through blood vessels in the umbilical cord.

Waste products and carbon dioxide from the baby are sent back through the umbilical cord blood vessels and placenta to the mother's circulation to be eliminated.

Answer:

The Cell Nucleus

Explanation:

Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or (mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

The cell's genetic material is contained in the nucleus.

Cells, frequently referred to as the "building blocks of life," make up all living organisms, ranging in number from the single cell of bacteria to the trillions in humans.

Each of these cells is a distinct entity enclosed in a cell membrane and containing a viscous liquid substance known as cytoplasm.

The majority of the DNA in human cells is located in a region of the cell called the nucleus. It's referred to as nuclear DNA.

DNA's primary role in a cell is to store the genetic data necessary for an organism to grow, function, and reproduce. Each creature is unique because of the information that is stored in its DNA and can be handed down from one generation to the next.

Therefore, the nucleus of the cell contains genetic material.
