Answer:

Diazotrophs

Explanation:

The nitrogen-fixing bacteria and other micro organisms that fix nitrogen are collectively called 'Diazotrophs'. There are many strains of these bacteria in soil, which perform this function. They are important agents in the 'Nitrogen Cycle'.

There are two main groups of organisms that fix nitrogen in the soil: diazotrophs and cyanobacteria.

Diazotrophics are bacteria that can convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can use. Some examples of diazotrophs include Rhizobium, which is found in the root nodules of legumes, and Azotobacter, which is a free-living bacterium.

Cyanobacteria are photosynthetic bacteria that can also fix nitrogen. They are found in aquatic and terrestrial environments, and they can play an important role in the nitrogen cycle.

While a general association between skull size and brain capacity exists, the intricacies of brain development and cognitive abilities extend beyond skull size alone.

The associations between skull size and brain capacity can provide valuable insights into the relationship between these two variables. Here are some observations that can be made:

1- Generally, there is a positive correlation between skull size and brain capacity. Larger skulls tend to accommodate larger brains. This is because the skull acts as a protective casing for the brain, and as the brain grows, the skull expands to accommodate it.

2- However, it is important to note that skull size alone does not provide a complete measure of brain capacity or intelligence. There can be variations in brain size within individuals with similar skull sizes, and factors such as brain structure, neural connections, and neuronal density also influence cognitive abilities.

3- Comparisons across species can reveal variations in the relationship between skull size and brain capacity. For example, some species may exhibit larger skulls relative to their brain sizes, suggesting adaptations for other functions such as jaw strength or sensory capabilities.

An example of structural adaptation is a spike on a bearded dragon (option A).

Adaptation in biology is an instance of an organism undergoing change, or the structure or behavior that is changed.

Adaptation can either be structural or behavioural depending on the change that occurs:

An adaptation can be structural, meaning it is a physical part of the organism. An adaptation can also be behavioural, affecting the way an organism responds to its environment.

An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts. Plants called succulents have adapted to this climate by storing water in their short, thick stems and leaves.

Explanation:

Answer/Explanation:

The water cycle shows the continuous movement of water within the Earth and atmosphere. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).

Hence it is quite important to understand and learn the processes of the water cycle.

Step 1: Evaporation. The water cycle starts with evaporation. ...

Step 2: Condensation. ...

Step 3: Sublimation. ...

Step 4: Precipitation. ...

Step 5: Transpiration. ...

Explanation:

Fossil fuels are a major source of greenhouse gases, which trap heat in the atmosphere and cause global warming.

When fossil fuels are burned, they release carbon dioxide, methane, and other greenhouse gases into the atmosphere. These gases absorb infrared radiation from the sun, which warms the Earth's surface.

The burning of fossil fuels is the main cause of the increase in greenhouse gases in the atmosphere. Since the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has increased by about 40%. This increase in greenhouse gases is causing the Earth's temperature to rise, leading to a number of changes in the climate, such as more extreme weather events, rising sea levels, and melting glaciers.

The brain and spinal cord are part of the central nervous system.

The electrical charges that act as nervous signals are called action potentials or nerve impulses.

Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.

After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.

Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.

Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.

Muscles move endo- and exoskeletons by contracting and relaxing.

Fertilization is the joining of two gametes called sperm and egg.

A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.

The two levels of classification used to identify plants for floral design purposes are the genus and species.

These are part of the binomial nomenclature system developed by Carl Linnaeus in the 18th century and are used to provide a universal and standardized naming system for all living organisms.

The genus is a grouping of closely related species, and the species is a group of plants that share common characteristics and can interbreed to produce fertile offspring. Together, the genus and species names form a unique two-part name that identifies a specific plant.

For example, in the plant species Rosa, the genus is Rosa, and the species name could be Rugosa, Canina, or any other name that follows the genus name.

Identifying plants for floral design purposes using their genus and species names is essential for ensuring that the right plant is used for a specific purpose. It helps florists to choose the appropriate plant based on the plant's characteristics, such as color, texture, and size, ensuring that the final floral arrangement meets the customer's needs and expectations

Answer:

Roots have specialized cells called root hair cells that are responsible for absorbing water and mineral ions like nitrates from the soil. These cells have long thin projections that stick out into the soil.

For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. This movement of ions from a low concentration in the soil to a higher concentration in the plant is achieved through a process called active transport. Active transport is a process that is required to move molecules against a concentration gradient. This means that substances are moved from a low concentration to a high concentration, which is the opposite of what would happen naturally. The process requires energy.

In the case of root hair cells absorbing nitrate ions from soils with low nitrate concentrations, active transport allows the plant to take in the ions it needs from the soil around it. The energy required for this process is produced by respiration.
