Answer:

The Biosphere

Explanation:

The biosphere is a thin life-supporting portion on Earth's surface, extending  a few km into the atmosphere to the deep-sea. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.

Both the personal items and the lab materials should be arranged neatly along the edge of the table.

All of an organism's characteristics are inheritable which evolves over millions of years. An example of this is the modern day horse's foot.

This is referred to as the change in the heritable characteristics of biological populations over successive generations.

All an organism's characteristics can be inherited and evolves over a period of time as a result of the changing environmental conditions which helps them to adjust thereby increasing their chances of survival hence preventing extinction of species.

For example, over millions of years of evolution, many horses lost their side toes and developed a single hoof as a result of them needing to move at faster speeds to evade predators.

Answer:

They are considered to be vestigial structures.

Answer:

The plant cell converts the most food into energy because it contains chloroplasts, which are organelles that are responsible for photosynthesis. Photosynthesis is the process in which plants use light energy from the sun to convert carbon dioxide and water into glucose. This glucose is then used as an energy source for the cell. The other cells do not contain chloroplasts and therefore cannot conduct photosynthesis, so they are not able to convert as much food into energy.

The dependent variable measured in the researcher’s experiment is the concentration of the drug in the blood samples. One control that the researcher could use to improve the validity of the experiment is to ensure that the same amount of the drug is administered to each participant.

Analyzing blood samples at many intermediate time points instead of at only the beginning and the end of the 20-week period allows the researcher to track changes in the concentration of the drug over time. This gives a more accurate picture of how the drug is metabolized by the body and how it affects the participants.

According to the given that actual flower position is dominant over terminal flower.

When an organism possesses two copies of the same dominant allele, it is said to be homozygous dominant, and when it possesses two copies of the same recessive gene, it is said to be homozygous recessive.

When an organism is homozygous, it contains two copies of the same allele for a gene. When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.

When an organism is heterozygous, it has two distinct alleles of the same gene. For instance, pea plants can have either homozygous dominant (red-red) or heterozygous red blooms (red-white). They are homozygous recessive if they have white blooms (white-white). Heterozygous carriers are always present.

answer to the question of how you can find the answer is by finding the answer

lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, exhalation

The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and handling of bioactive materials.

The respiratory system is responsible for obtaining oxygen and getting rid of carbon dioxide and aiding in the speech production and in sensing odors.

parts of respiratory system:

Nose

Mouth

Throat (pharynx)

Voice box (larynx)

Windpipe (trachea)

Airways (bronchi)

Lungs

Most living things need the oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into the energy. Humans get oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells ability to break down food in order to get the energy we need to survive.

The person that developed the model  are James Watson and Francis Crick. The bases are found in In 1953 are: adenine, cytosine, guanine, and thymine.

In 1953, James Watson and Francis Crick developed the model of the structure of DNA, which is shown in the image below. The model, known as the double helix, consists of two strands of DNA that are coiled around each other.

Hence, DNA is made up of four bases: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases pair up with each other in specific ways: A pairs with T, and C pairs with G. The sequence of these bases on a DNA strand carries genetic information, and the specific order of the bases determines the genetic code for an organism.

9 of the offsprings will be dominant for both traits in the above dihybrid cross.

A dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes.

Gregor Johann Mendel known as the father of genetics was the first person to discover the basic principles of heredity during the mid-19th century.

In a dihybrid cross between two parents that are heterozygous for both traits, the cross will result in four different combinations of seeds in the F2 generation as follows:

The enzyme called tyrosinase produced the dark compound in the skin (melanin) but in albinism, this enzyme does not work or is not present, thereby this mutation could be responsible for Albinism because this phenomenon alters the molecular signaling pathway involved in the synthesis of skin pigments.

The relationship between genetic mutations and the alteration of signaling molecular pathways is based on the fact that alteration in the genetic material can lead to defective proteins involved in a signaling network, thereby altering the final outcome of the pathway.

Therefore, with this data, we can see that the relationship between genetic mutations and the alteration of signaling molecular pathways is based on the molecular mechanisms that are altered during the generation of a phenotypic feature such as in this case skin pigmentation.

Explanation:

The model prepared by Tia could be used to show the glaciers which carry soil as similar to the clay which carries the ice cubes and sand, the glaciers also carry various materials along with them.

A glacier is a persistent body of dense ice and other materials that is constantly moving under its own weight and force. A glacier forms where the accumulation of snow exceeds the ablation over the period of many years, often centuries.

Glaciers acquire the distinguishing features, such as crevasses and seracs, as it slowly undergoes flow and deforms under the stresses which are induced by its own weight. As it moves constantly, it abrades rocks and debris from its substrate to create the major landforms such as cirques, moraines, or fjords. Although a glacier may flow into a waterbody, it forms only on the land surface and is distinct from that of much thinner sea ice and lake ice which form on the surface of bodies of water.
