A. They use their trunks to make loud sounds.
B. They stomp their feet to create noise.

Answer:
How do elephants warn each other?
When they're excited, scared or happy, elephants make the trumpeting sounds you're probably familiar with. They vocalize in other, more complicated ways, too — low-pitched rumbles outside our range of hearing. At less than 20 hertz, these infrasonic calls are often used to alert each other to danger.

Answer:
Colonization by plants may provide habitat, facilitating colonization of animal species.
Early colonizing plants may increase the nutrient level of the soil, facilitating the colonization of other plant species.
Animal colonizers may increase pollination of some plant species, facilitating their colonization.
Explanation:
The plants provides habitat as well as food to organisms that helps in the colonization of that organisms because every organism needs food and living place for its survival. Some plants increase the nutrient level in the soil through fixation of nitrogen which leads to the colonization of other plant species in that environment. Some animals causes pollination of plants which helps them in their colonization so all these organisms have a positive impact on the occurrence of other species.
Why is it important for nitrogen to be more abundant in our atmosphere than oxygen?
A. Oxygen is only breathable if diluted with nitrogen.
B. Nitrogen and oxygen combine to produce weather that is essential for life.
C. Oxygen must be diluted because it is a highly combustible gas.
D. Nitrogen is a heavy molecule that pulls oxygen, a light molecule, to the surface for oxygen-dependent life to use.
Answer:
Oxygen must be diluted because it is a highly combustible gas
Explanation:

D)
thunderstorms
A weather map has been shown for the southern United States. According to the map, tornadoes are most closely associated with thunderstorms weather event. Thus, option D is correct.
What is the use of map in weather or garden?
Map is the distribution of flower in a garden. A diagram has been used to label an object so the parts can be recognised easily. A 3-D model has a xerox copy of the object in a three dimensional figure . An information a word so one can assume infographic . A map helps to represent the layout of the land or distribution of flower in garden.
Geographic information system (GIS) has been analyzed and visualize data for geographic positions on Earth's surface. GIS has computer - based tool that examines spatial relationships, pattern and trends. By connecting geography with data, GIS better understands data using a geographic context.

Which step in the Gram stain is the critical step in differentiating Gram negative cells from Gram positive cells?
Answer:
The rapid decolorization with ethanol or acetone
and counterstaining with safranin
When a decolorizer such as alcohol or acetone is added, it interacts with the lipids of the cell membrane. A gram-negative cell loses its outer lipopolysaccharide membrane, and the inner peptidoglycan layer is left exposed: when safranin is added they will turn red. Conversely, gram-positives retain the Cristal violet and will color in purple
The first phase of Mitosis is _________ . In this phase the DNA condenses down into ________, and the duplicated separate. The second phase of Mitosis is_______ . In this phase the sister chromatids line up on the _______ plate through a push and pull motion as they connect to the microtubule spindle fibers emanating from the ________. The third phase of Mitosis is________ . In this phase the________ (sister chromatids or homologous chromosomes) are pulled apart. The fourth phase of Mitosis is_______ . In this phase the nuclear ________starts to reform and the DNA de-condenses.
MITOSIS:
This question is describing the process of mitosis, a kind of cell division that results in two genetically identical daughter cells. Mitosis consists of four stages namely: prophase, metaphase, anaphase, and telophase etc. PROPHASE is the first stage of mitosis where DNA condenses down into CHROMOSOMES, and the duplicated separate.METAPHASE is characterized by the lining up of sister chromatids at the CELL PLATE through a push and pull motion as they connect to the microtubule spindle fibers emanating from the CENTROSOME. ANAPHASE is the third stage of mitosis in which duplicated chromosome/sister chromatids are pulled apart into opposite poles. The fourth stage is TELOPHASE where the NUCLEAR MEMBRANE starts to reform and the DNA de-condenses.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

Starting with spore dispersal, and identify adaptations in the life cycle of the bryophyte for living in a terrestrial environment (ie, in air, without water surrounding the plant body). What are new stresses associated with living on land, and what morphological or physiological features did the first land plants have to evolve to cope with these stresses
Answer:
Stresses such as lack of nutrients, space, competition and water availability.
Explanation:
Lack of nutrients, space, competition and water availability are the stresses that the bryophyte can experience by living on land. The morphological or physiological features such as lowering transpiration rate by stomata, attain specialized structures to collect sunlight and fulfill water requirement by absorbing water from the air if no water is available in the soil etc are the features that the plant has to attain to cope with these stresses.
how does the structure of simple cuboidal connect to its function
Answer:
Simple cuboidal epithelial tissue is specialized for diffusion and absorption. The reason our kidneys function the way they do is because of the movement of water and salts in and out of the kidney tubules.Likewise, the cuboidal shape of the cells allows greater surface area for absorption to take place.

We have 13 different clotting factor proteins in our blood. Do you think hemophilia is controlled by one or multiple genes?
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Basically it's whatever you believe it is.
