Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

Explanation:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can  recognizes two factors: measure of light and development of a plant.  

The adjustment in light influences the development of a plant. Both the two factors are measurable.  

Cause-Independent Variable: measure of light  

Impact Dependent Variable: development of plant  

2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.  

Answer:

The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.

The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.

The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.

Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.

Answer:

1. Decrease

2. Photosynthesis

3. Cellular respiration

Explanation:

Photosynthesis in a plant requires light source to occur. The photosynthetic process gives oxygen gas (O2) as a waste product. This means that the production of oxygen is dependent on the intensity of light.

On the other hand, cellular respiration uses up or consumes oxygen in a plant. Hence, an increase in respiration reduces oxygen level if photosynthesis does not produce.

According to this question, If you move a plant further and further away from a light source, the level of O2 production would DECREASE because the process of PHOTOSYNTHESIS slows and the process of CELLULAR RESPIRATION speeds up.

It is true that DNA can store information, can be replicated, and can undergo rare changes.

Deoxyribonucleic acid, or DNA, is a molecule that has the capacity to store genetic data in the form of a code that determines the order of nucleotides. The transmission of traits from one generation of cells to the next is made possible by the replication and transmission of this information.

Rare alterations in DNA, known as mutations, have the potential to modify the genetic information stored inside. As a result of exposure to mutagens like radiation, chemicals, or viruses, these mutations may take place spontaneously or as a result of exposure. From having no discernible impact to producing genetic illnesses or aiding in the growth of cancer, mutations can have a variety of repercussions on the organism.

Answer:

Fiber

Explanation:

Fiber is one kind of carbohydrate which is indigestible by the body. Fiber is a part of plant foods which is not digestible for our body.

Fiber is the food component that is indigestible by the body. Therefore, option (B) is correct.

Fiber is a type of carbohydrate found in plant-based foods that the human body cannot digest or absorb. It passes through the digestive system relatively intact and provides several health benefits. There are two types of dietary fiber: soluble and insoluble.

Soluble fiber dissolves in water to form a gel-like substance in the digestive system, which can help lower cholesterol levels, regulate blood sugar, and promote feelings of fullness. Examples of foods that are high in soluble fiber include oat bran, beans, apples, and citrus fruits.

Insoluble fiber, on the other hand, does not dissolve in water and helps to add bulk to stool, promoting regular bowel movements and preventing constipation. It also helps to keep the digestive system healthy by feeding beneficial gut bacteria. Examples of foods that are high in insoluble fiber include whole grains, nuts, seeds, and dark leafy greens.

Including a variety of high-fiber foods in the diet can have numerous health benefits, including improved digestion, lowered risk of heart disease, and better weight management.

The order of sperm development, beginning with the germ (stem) cell from which all sperm develop, is as follows: Spermatogonia, Primary spermatocyte, Secondary spermatocyte, Spermatid, and Spermatozoa.

Sperm development, also known as spermatogenesis, is a complex process that takes place within the testes. It begins with spermatogonia, which are undifferentiated germ cells. Through the process of mitosis, spermatogonia divide and differentiate into primary spermatocytes. These primary spermatocytes undergo meiosis I, a type of cell division that reduces the number of chromosomes by half, resulting in secondary spermatocytes.

Secondary spermatocytes then proceed through meiosis II, another round of cell division that maintains the same number of chromosomes, to form spermatids. At this stage, spermatids are haploid cells, meaning they contain only one set of chromosomes. The spermatids then undergo a process called spermiogenesis, during which they transform into mature sperm cells known as spermatozoa. This transformation includes the development of a tail for motility and the condensation of the nucleus.

Spermatozoa are then released into the seminiferous tubules, where they continue to mature and gain the ability to swim. Once fully mature, the spermatozoa are stored in the epididymis until they are released during ejaculation. Throughout this entire process, sperm development is regulated by various hormones, including testosterone and follicle-stimulating hormone (FSH).

The time during prenatal development when the major body structures form is the prenatal stage.

The time leading up to delivery is known as the prenatal period. During this period, a woman needs more nutrients than usual. The embryonic stage of prenatal development is when the primary bodily structures begin to take shape. The first eight weeks of pregnancy are usually when it occurs, and this is an important period for development of an embryo's primary organs.

Additionally, it is essential for the growth of several systems, including the digestive, cardiovascular, and neurological systems.

South America and Africa suggests that both continents were joined together at one point. The reason for this suggestion is that the east coast of South America fits the west coast of Africa like pieces of a puzzle. This interlocking pattern suggests that the two continents were once joined together.

The idea that South America and Africa were once joined together as a single continent is supported by geological evidence. Rocks on both continents show similar patterns of folding, faulting, and mountain building. Additionally, fossils of the same plants and animals have been found on both continents.

This supports the theory that the two continents were once connected and that animals and plants were able to migrate between them. While the exact timing of when the two continents separated is not certain, it is believed to have occurred around 200 million years ago during the breakup of the supercontinent Pangaea.

Ions, polar molecules, and large molecules cannot readily cross a lipid bilayer and are dependent on transport proteins to cross a membrane. The classify for uniport, symport, or antiport transport system are glucose transporters is uniport, dium-glucose co-transporters is symport, and sodium-potassium ATPase is symport.

Uniport, symport, or antiport transport system are the three types of membrane transport systems. For molecules that cannot readily cross a lipid bilayer and are dependent on transport proteins to cross a membrane, these are the different transport systems that are used. Uniport is a transport protein that carries only one molecule or ion in a particular direction. It is a protein that transports a single molecule or ion at a time. Glucose transporters are an example of this.

A symport is a transporter that moves two molecules or ions across a membrane at the same time, in the same direction. Sodium-glucose co-transporters are an example of symport, where both sodium and glucose are transported together. An antiport is a transporter that moves two molecules or ions in opposite directions. Sodium-potassium ATPase is an example of an antiport, where sodium is transported out of the cell and potassium is transported into the cell.
