In the initial period of learning, ________ describes when an organism learns to connect a neutral stimulus and an unconditioned stimulus. acquisition conditioning extinction neutral stimulate

The right options are;

1. b. rise

2. b. submarine canyons

Continental rise is the bottom feature of water that is composed of thick sequences of continental substances that coalesced between the continental slope and the deep ocean floor. Continental rises occurs due to three sedimentary processes which are vertical accumulation of biogenic and clastic substances, mass wasting and the deposition from contour currents.

Submarine canyons are deep, narrow steep-sided valleys that emanate from the continental slope and sometimes may extend to the ocean basin floor (continental shelf). The physical appearance of submarine canyons resembles canyons formed by rivers on land.

The answer is unregulated mitotic division.

This occurs due to the failure of tumor suppressor factors such as the p53 proteins. These tumor suppressors are involved in the checkpoints of cell cycles especially when they are damage to DNA. They are also involved in the apoptosis of such cells. The unchecked activation of cyclin-dependent kinases causes unregulated progression of mitosis.

the following correctly describes plant and animal adaptations of a particular biome is Savanna plants have deep root systems and tundra animals have fur or feathers with seasonal color variations.

The correct option is (b).

1. The Savanna biome is characterized by hot and dry conditions, with periodic droughts. Savanna plants have adapted to this environment by developing deep root systems that can reach water stored deep underground, allowing them to survive during dry periods.

2. In contrast, the Tundra biome is characterized by cold temperatures and a short growing season. Tundra animals have adapted by growing thick fur or feathers with seasonal color variations, which help them blend into their surroundings and provide insulation against the cold temperatures.

3. These adaptations in both plants and animals are essential for their survival in their respective biomes, allowing them to thrive despite the challenging environmental conditions.

Answer:

even

Explanation:

1. Clumped - When the organisms are arranged in such a way they are clustered together in a group.

2. Random - In this, the organisms are randomly distributed in a non-uniform manner.

3. Even - when the organisms are arranged evenly over an area.

A large number of sunspots indicates an active phase in the solar cycle with increased magnetic activity on the Sun's surface. It also suggests heightened solar activity, such as flares, and signifies a period close to the sunspot maximum phase of the cycle.

Observing a large number of sunspots suggests that the Sun is in an active phase of its solar cycle. Sunspots are large, dark features on the Sun's surface due to increased magnetic activity. They are cooler regions compared to the surrounding areas, typically around 3800 K versus the brighter regions at about 5800 K. The occurrence of sunspots is associated with the solar cycle, which has an average period of 11 years, fluctuating between periods of sunspot maximum and minimum.

During the maximum phase, more than 100 spots can often be seen on the Sun’s surface. The frequency and number of sunspots can also indicate heightened solar activities such as solar flares, which occur more often near sunspot maximum and contribute to more conspicuous solar phenomena like a stronger solar corona. Careful and regular observation allows one to track these sunspot cycles and understand the patterns of increased and decreased solar activity.

The statement is true: fungi can indeed be both unicellular, like yeasts including Saccharomyces cerevisiae and Candida species, and multicellular, forming complex structures such as molds and mushrooms. Dimorphic fungi can even switch between these states depending on environmental conditions.

The statement that fungi can be unicellular and multicellular is true. Fungi include a wide range of organisms with diverse characteristics, from microscopic yeasts to large, complex molds and mushrooms. For example, yeasts, like Saccharomyces cerevisiae (baker's yeast) and Candida species (known for causing thrush), are unicellular fungi, thriving in various environments and under different conditions. On the other hand, multicellular fungi develop complex structures, such as molds and mushrooms, with networks of hyphae contributing to their vegetative body, known as a thallus. Notably, some fungi, known as dimorphic fungi, possess the remarkable ability to switch between unicellular and multicellular forms depending on environmental conditions. This dual nature highlights the adaptability and diversity within the fungal kingdom.

Archaea and Eubacteria, kingdoms in the domains Archaea and Bacteria, are composed of prokaryotic organisms that lack a membrane-bound nucleus and are adapted to a wide range of environments, including extreme ones.

Archaea and Eubacteria are kingdoms composed of organisms that do not have a membrane-bound nucleus. These single-celled organisms are from the domains Archaea and Bacteria, which are classified as prokaryotes due to the absence of a nucleus. Both domains are known for their diverse habitats and functions, inhabiting environments ranging from moderate to extreme. Archaea, for instance, can often be found living in conditions such as hot springs, salt flats, and other challenging environments, showcasing their remarkable adaptability.

While prokaryotes lack a nucleus, they do possess a singular piece of circular DNA located in the nucleoid region of the cell, as well as ribosomes for protein synthesis. The cell walls of these organisms are also characteristic, with bacteria having a cell wall containing the polysaccharide peptidoglycan, contrasting with the varied composition found in archaeal cell walls.

These differences underscore the distinct evolutionary pathways of Archaea and Bacteria, with the former presenting uniqueness in genetics, metabolic pathways, and cell membrane structure when compared to their bacterial counterparts.

Answer: climate

Explanation:

Climate can be define as the average state of the long term atmospheric condition. It can be describe as the stable weather condition which did not changed over a period of 30 years. It measured by determining the change in the patterns of the variations of temperature, atmospheric pressure, precipitation, humidity and other meteorological variables of a region for a long period of time.

Answer:

The correct answer is - false.

Explanation:

The nerve root is the beginning part of a nerve that leaves CNS and the spinal cord. It is the initial part of the nerve that is present in between the intervertebral disks and runs through spines which acts as a shock absorber and protects these nerves to any type of damage to these nerves.

The nerve root is not the component of the inter-vertebral disks but initial part of the nerves which are protected by these shock absorbers.

Thus, the correct answer is - false.

Answer:

Nucleus

Explanation:

Answer: A=Validate, because energy cannot be created or destroyed but can change forms.

Plants absorbs energy from sun, to prepare their food in the form of carbohydrates by photosynthesis.This chemical energy from food is required by the plants for cellular metabolism. The same process will occur in sea grass.

The law of conservation of energy, says that energy can neither be created nor be destroyed, but it can change it's form. In the given situation, the sunlight energy is converted into chemical energy in plants. Therefore, it can be said that radiant energy from the sun is conserved in the form of chemical energy in sea grass.

Therefore, the results of the experiment, is validate, because energy cannot be created or destroyed but can change forms.

Final answer:

Sponges have specialized but independent cells like pinacocytes, porocytes, amoebocytes, and choanocytes which allow them to filter-feed and regenerate. These cells are not organized into tissues but work in unison to support the sponge's structure and functions.

Explanation:

How Sponge Cells Are Alike

The cells in a sponge are functionally specialized and exhibit a high degree of independence compared to the cells of more complex animals. Sponges are among the simplest of metazoans, with key cell types including pinacocytes (forming the outer layer), porocytes (forming pores), amoebocytes (involved in digestion and distribution of nutrients), choanocytes (filter-feeding and moving water), and splenocytes (forming a skeleton).

Crucially, these cells are not organized into true tissues but still create a cohesive multicellular organism. Sponges are able to regenerate if broken apart and passed through a sieve, with the different cell types reassociating to reform the sponge structure. This is in contrast to more complex organisms, where individual cell types cannot survive alone.

The choanocytes play a particularly critical role, as they bear resemblance to choanoflagellate protists and are essential for the sponge's filter-feeding mechanism. They possess flagella that draw water through the sponge, facilitating the extraction of nutrients and removal of waste through the osculum.

Answer:

Telephone wire

Explanation:

The spinal cord can be compared to a telephone wire. This is because both of these objects operate in similar ways. A telephone wire allows a message to be transmitted from the speaker to the listener. In a similar way, the spinal cord allows a message to travel between your body and your brain, fulfilling an important role.

50% of the progeny will be green and the other 50% will be white when the cross takes place between the heterozygous green plant and the homozygous white plant.

A monohybrid cross takes place between two parents with a single trait. An example is the color of a pea plant. Green colour is dominant over white. The green is represented by G. White is represented by g. The homozygous dominant for green is represented by GG. The heterozygous green is represented by Gg. The homozygous white is represented by gg. 

When there is a cross between the heterozygous green and homozygous white plant , 50% of green progeny and 50% of white progeny will be formed. The heterozygous parent will form two gametes, such as G and g. The punnett square is explained in the image. 

Hence, from the cross of heterozygous green parents and homozygous recessive parents, 50% of green offspring and 50% of white offspring would be formed.
