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:Nutrient cycling rate depends on various biotic, physical and chemical factors. Examples of a nutrient cycle: carbon cycle, nitrogen cycle, water cycle, oxygen cycle, etc. Energy Flow and Nutrient Cycle

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.

Answer:

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

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.

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,

Body systems must work together. If one system will be damaged or fails, the other systems will be affected. If the digestive system will be fail, digestion will fails. Water will not be absorb that will lead to the circulatory system to have difficulty in the consistency of blood. If there is a presence of digestive disease, there will be an interference in the digestion as well. Other organ functions will be affected, too. Several effects will be seen such as dehydration, poor absorption of nutrients, blocked blood flow, etc. If the digestive shuts down due to damage of muscles or nerves, it may cause nausea, vomiting, lack of appetite and malnutrition. The nervous and circulatory systems work with the digestive system and these systems are greatly affected if it will not work properly.

The respiratory system is affected if the digestive system fails. These two systems work together to provide power to the entire body system. If digestion fail due to overeating, it can cause abdominal bloating. Bloating can lead to shortness of breath.

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. The supraspinatus muscle tendon passes laterally beneath the cover of the acromion.

Some natural causes of deforestation are:

- Earthquakes (cutting down trees when in the higher scales);

- Biological pests;

- Dessertification process;

- Natural climates changes (seasonality and geological change can lead to natural climate change).

The correct option is D. A change in the regional climate resulting in a period of drought, as indicated by the increase in oxygen and sulfur in the tested samples, caused the failure of the Mayan civilization. Both variables, oxygen and sulfur, increased prior to Mayan collapse. Their increase could underlie climatic changes that led to Mayan people disappearance.

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.

It is true that even though animal nervous systems vary in complexity, their nerve cells are remarkably similar.

Nerve systems exist in nearly all multicellular animals, though their complexity varies greatly. The only multicellular animals without a nervous system are a sponge and the placozoan and mesozoan organisms, both of which look like tiny blobs. With the exception of a few worm species and echinoderms, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord. The nervous system of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish) are made up of a diffuse nerve net.

The most fundamental functions of the nervous system are to direct an organism's movement and to influence its environment (such as through pheromones). To accomplish this, signals are sent from one cell to another or from one area of the body to another. The sources of the output that the nervous system produces are signals that travel to muscle cells and cause the activation of muscles, and signals that travel to endocrine cells that cause the release of hormones into the bloodstream or other internal fluids.

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.

The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.

As we know exoskeleton is a characteristic of arthropods and other invertebrates, all vertebrates like us humans have an endoskeleton so they could not present such characteristics, finally, worms do not possess an exoskeleton, true that they are invertebrates however their phylum implies a soft body. Therefore the correct answer is option B.

The correct answer is II. Poor sanitation. This increases transmission of infectious disease which harms life expectancy. In the worst cases it creates epidemics that decimate populations, like black death in the eighteen century.

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.
