The statistical test that is common for genetics and tests observed data against the probability of those values is the chi-square test.

A statistical technique called the chi-square test is used to compare actual outcomes with predictions. The goal of this test is to establish whether a discrepancy between observed and expected data is the result of chance or a correlation between the variables you are researching.

What is studied in genetics?

The study of genes and heredity, or how particular characteristics or traits are passed from parents to offspring as a result of changes in DNA sequence, is known as genetics. A gene is a section of DNA that has the instructions needed to create one or more molecules that support bodily function.

Therefore, the chi-square test is a statistical test that is common for genetics and tests observed data against the probability of those values.

If a mating between a black animal and a brown animal produced all black offspring, then the most likely hypothesis is that color is controlled by complete dominance and black animal parents are homozygous for this trait.

In genetics, complete dominance refers to the phenomenon for which one allele of a gene masks another allele of the same locus in order to express a given trait.

Therefore, with this data, we can see that complete dominance is caused when an allele masks the expression of the recessive allele in heterozygous individuals.

Answer: I think maybe you could make an illustration about the process of photosynthesis and cellular respiration. Maybe you could print some images like the sun, leaves, and molecules. In the molecules like oxygen, carbon dioxide, water, you could just make small circles. You can put it all together by adding arrows to show the next step of the process.

2. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP. Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. The bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Carbon dioxide and water are created as byproducts. This process occurs in mitochondria.

3. In the two processes, we can see that the products of one process are reactants of another – and vice versa. Glucose and oxygen – which happen to be the products of photosynthesis, are required to facilitate cellular respiration, while carbon dioxide – which is a by-product of cellular respiration, is required to facilitate the process of photosynthesis.

Explanation: A ligament is a fibrous tissue that connects bone to bone. Usually holds to serve as a structure together and keep them stable.

Natural gas may also be produced from organic material at high enough pressure. The two basic factors that convert biological matter into fossil fuels are heat and pressure.

Algae and plants inhabited shallow oceans millions of years ago. The organic material was buried when it perished and sank to the bottom, where it mingled with other materials. The remnants of these animals were converted into fossil fuels over millions of years under extreme pressure and heat.

Layers of clay and sand have been covering dead creatures that were buried in the water millions of years ago. These decomposing organisms became petroleum and natural gas as a result of the lack of air, the high temperature, and the high pressure.

Only carbon and hydrogen are necessary for the conversion of organic matter (OM) into petroleum.

The possible combinations form from an offspring in which parents have  ST and st genotypes is SSTT, SSTt, SStt, SsTT, SsTt, ssTT, ssTt and sstt, it is supposing that S and T genes are not linked.

In offspring, genes are inherited as independent units in the case that genes are not located on the same chromosomes. This law is known as the principle of independent segregation.

In this case, parents may form all types of gamete combinations and therefore offspring may exhibit any combination.

Therefore, with this data, we can see that parents in this case may form different gamete combinations for S and T genes that will be inherited in offspring.

Explanation:4 Common Biogeochemical Cycles: (explained with diagram) Some of the major biogeochemical cycles are as follows: (1) Water Cycle or Hydrologic Cycle (2) Carbon-Cycle (3) Nitrogen Cycle (4) Oxygen Cycle. The producers of an ecosystem take up several basic inorganic nutrients from their non-living environment.

Life processes are the fundamental tasks carried out by living things to maintain their own existence. Apart from nutrition and respiratIon other live functions performed by living things include; Excretion and MOVEMENT

Relationship between life functions and homeostasis

Homeostasis is  a self-regulating process that controls internal factors needed to maintain life. In other terms, homeostasis is a system that maintains a constant environment inside an organism despite changes in the outside.

Excretion

All living things produce poisonous materials as a result of various metabolic processes. These wastes are eliminated from the body by excretion. Animals mostly create carbon dioxide and nitrogenous wastes as waste products (ammonia, urea, uric acid).

In order to maintain internal stability waste Produced by cellular metabolism are excreted

MOVEMENT

Mammals, fish, amphibians, birds, advanced invertebrates, and reptiles (excluding snakes) have  organs for locomotion. Animals move around in order to find food, avoid predators, and survive unfavorable environmental conditions.

Joints and muscle contractions allow animals to move their body parts

Some organisms, like the tentacles of a sea anemone, are fixed in position but can move their individual sections.

Plants use their roots to cling to the soil.

DURING MOVEMENT living thing especially animals make use of the Nervous System to carry out homeostasis such as the Cranial nerves, spinal nerve which helps to transport sensory data from the CNS to motor impulses, the Cerebrum which  helps to maintain  consciousness, creativity, thinking, morals, and memory, Mindfulness, originality, ideas,

The infraspinatus muscle is included in the rotator cuff muscles.

Infraspinatus muscle are found  on the dorsal surface of the scapula, deep to trapezius, and parts of the deltoid. The infraspinatus is a portion of the rotator cuff muscles composed of the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles act to stabilize the glenohumeral joint.

The supraspinatus muscle abducts the upper arm. The infraspinatus muscle externally rotates the upper arm at the shoulder. The supraspinatus muscle originates from the supraspinous fossa, which is a concave surface at the top of the scapula.

Both variables, oxygen and sulfur, increased prior to Mayan collapse. Their increase could underlie climatic changes that led to Mayan people disappearance.

The potential energy is the energy that depends upon relative position or various part of a system and the potential charge that a molecule have. The molecules of ATP, nitrogen, and glucose have high potential energy, as well as the ion gradient in a cell membrane, however the concentration gradient does not require neregy input, since the energy stored in it is the one used to balance the concentrations.

Red blood cells will osmotically absorb water from a solution (such as pure water) that has a greater water concentration than their contents, swell up, and rupture. A higher concentration of water outside the cell will diffuse into a lower concentration of water inside the cell.

Osmosis happens when there is an inverse relationship between the concentration of solutes and the gradient in water concentration across the membrane. Osmosis continues to take place until the water concentration gradient is zero or the hydrostatic pressure of the water equals the osmotic pressure.

An animal cell would swell and explode if it were put in a drop of 100 percent pure water. This would occur because osmosis is permitted by the semi-permeable nature of the cell membrane.

At normal pressure and temperature, the water potential of pure water is always assumed to be zero. The kinetic energy that water molecules contain may be used to explain it.
