1) environmental stimulus 2) sensory receptors 3) brain 4) memory 5) behaviour.

(1) Environmental stimulus: A stimulus is any detectable change in an animal's environment that can potentially affect the animal's behavior. For example, a loud noise or the presence of food can be stimuli.

(2) Sensory receptors: When a stimulus is detected by an animal's sensory receptors (such as eyes, ears, nose, or skin), it sends signals to the animal's brain via sensory neurons.

(3) Brain: The animal's brain receives and processes the signals from the sensory receptors, which can result in the activation of specific neural circuits and the release of various neurotransmitters.

(4) Memory: Depending on the animal's past experiences, the stimulus may trigger certain memories and associations that influence the animal's behavior. For instance, if the animal has learned to associate a particular sound with danger, it may respond differently than if it had no prior experience with that sound.

(5) Behavior: Finally, the combined effects of the sensory input, brain processing, and memory can result in a change in the animal's behavior. The animal may move towards or away from the stimulus, vocalize, exhibit a particular social behavior, or engage in any other response that is appropriate for the situation.

Answer:

a reactant that is catalyzed by an enzyme

Explanation:

Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence

Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

A substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.

Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.

The reactant in an enzyme-catalyzed reaction is named a substrate.

Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.

Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

No, "Crick and Watson" is not a type of genetic test. Crick and Watson refer to James D. Watson and Francis Crick, who were scientists involved in the discovery of the structure of DNA. They proposed the double-helix structure of DNA in 1953, which provided the foundation for understanding genetic information and its role in heredity.

Genetic tests, on the other hand, are laboratory tests that analyze an individual's DNA or genes to provide information about their genetic makeup, potential genetic disorders, or predispositions to certain conditions.

These tests can be used for various purposes, such as diagnosing genetic disorders, predicting the risk of developing certain diseases, determining carrier status for genetic conditions, or providing ancestry and genealogical information.

While Crick and Watson made significant contributions to the field of genetics, they are not directly associated with genetic testing. Genetic tests are based on scientific advancements and technologies developed after their groundbreaking discovery of the DNA structure.

Exponential growth refers to a rapid and continuously increasing rate of population growth over time, resulting in a steep upward curve on the graph.

It took 1649 years for the world population to double, going from 0.25 billion people to 0.50 billion people. To double once again, it would take the same amount of time, approximately 1649 years. A third doubling would also take approximately 1649 years.

The population doubled for the second time in the year 1950. It took around 100 years for the population to double for the second time.

Extending the graph to the year 2015, you would add data points for that year. The specific values would depend on the available population data for that year.

According to the graph, the population is projected to reach 10 billion around the year 2050.

Based on the graph, it appears that the population of 2000 will double in approximately 40 years. However, since the specific year for the population value of 2000 is not provided, the exact number of years cannot be determined.

The graph illustrates exponential growth. This term means that the population is increasing at an accelerating rate over time. As the population grows, the rate of increase becomes more significant, resulting in a steep upward curve on the graph. This indicates a rapid and continuous growth pattern rather than a linear or constant rate of growth.

Bacterium are one of the few organisms that reproduce via asexual reproduction. This process involves the bacteria using binary fission to self-replicate, whereby one bacterium splits into two identical daughter cells.

Bacterium are some of the simplest organisms that are capable of reproducing asexually. Asexual reproduction in bacteria is accomplished through the process of binary fission, which is when one bacterium splits into two identical daughter cells.

During binary fission, the DNA of the single parent cell is replicated and then the two daughter cells divide, producing two genetically identical bacteria. This process of asexual reproduction allows bacteria to rapidly multiply, allowing them to quickly colonize new environments and respond to new challenges. This is why bacteria are some of the most successful and resilient organisms on the planet.

Methods of vegetative propagation include cutting, grafting, layering, division, sprouting, etc.

Vegetative propagation is a method of plant propagation that uses vegetative structures such as stems, roots and leaves to create new plants without the need for seeds. There are several methods of vegetative propagation, each suitable for different plant species and desired results. Here are some commonly used methods:

1. Cutting: This involves taking part of the stem or root of the mother plant and placing it in a suitable growing medium. Cuttings develop roots that eventually grow into new plants.

2. Layering: In this method, the plant's branches and stems are bent and partially buried in the ground. Roots develop from the buried part, and when they take root, they are separated from the mother plant and a new individual is formed.

3. Grafting: This technique involves joining the tissues of two different plants, the shoot (the plant of interest) and the rootstock (which provides the root system and support). Two plant tissues fuse and the shoot grows into a new plant with the desired plant characteristics.

4. Sprouting: Similar to grafting, sprouting involves attaching the shoots of the desired plant to a rootstock. New shoots develop from the shoots with the desired plant characteristics.

5. Tissue culture: This is a laboratory-based method of culturing plant cells or tissues in a nutrient-rich medium under controlled conditions. Cells divide and differentiate into whole plants and can be transferred to soil.

These vegetative propagation methods are widely used in horticulture and agriculture to propagate plants with desirable traits or to propagate plants that do not produce viable seeds.

Arthropods have appendages with joints. Arthropods do have legs in general.

A group of invertebrate animals known as arthropods has segmented bodies, jointed legs, and an exoskeleton. It is the invertebrate species' largest phylum. Their body is made up of segments and has two appendages. For terrestrial species, internal fertilization as well as external or internal fertilization is used for reproduction (aquatic species). Their circulatory system is open. Their development began during the Cambrian era. They serve as pollinators for crops and a source of food for people. Some species can infect people, animals, and crops with diseases.

All arthropods have joined limbs (arthro means joint, and pod means foot). The exoskeleton is rigid across much of the leg, but it is softer and pliable at the joints, allowing movement much like a suit of armor does.

All arthropods have moving body parts, joint legs, and claws. The bodies of arthropods are segmented. Typically, each body segment contains two appendages. The appendages may be mouthparts, legs, wings, or antennae.
