Wolves from the same pack are all feeding
on the same deer. What type of species
competition is this?
A. intraspecific
B. interspecific
C. invasive species
Answer:
A. intraspecific !!
Wolves from the same pack are all feeding on the same deer. What type of species. In this, the type of the species is intraspecific competition.
What do you mean by intraspecific competition?Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce.
Interspecific competition may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species.
Intraspecific competition occurs between members of the same species. For example, two male birds of the same species might compete for mates in the same area.

Answer:
metabolic activity
Explanation:
Elements can form covalent bonds and ionic bonds.
Answer:
Covalent bonds can form between atoms of the same elements (i.e. H2). However, ionic bonds cannot do this. Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal. Molecules formed by covalent bonds have a low melting point, whereas those with ionic bonds have a high melting point.

The graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degrees Celsius, and salinity in parts per thousand.
Image of two graphs. The left graph has the x-axis labeled temperature (degree C) ranging from 0 to 10. The y-axis is labeled depth below surface (km) ranging from -1.8 to 0. The line on graph goes up vertically starting at about 2 °C on the x-axis and -1.9 km on the y-axis. The vertical line goes up staying at about 2 degree C and climbs from -1.9 km to about -0.8 km. The line starts to shift right at -0.6 km. The line shifts to the right from 2 degree C to 5 degree C. The line shifts to right more starting at -0.5 km and reaches 10 °C around -0.2 km. The line continues up vertically after -0.2 km. The right graph has the x-axis labeled salinity ranging from 33.8 to 34.6. The y-axis is labeled depth below surface (km) ranging from -1.8 to 0. The line on the graph starts at 34 on the x-axis and 0 km on the y-axis. The line starts to shift to the right at -0.1 km and levels out at 34.2 on the x-axis. At -0.2 km the line shifts to the left and continues to shift left until it reaches -0.5 km. The line starts to shift to the right again at -0.6 and continues to shift right until it reaches -1.9 km on the y-axis and 34.6 on the x-axis.

Ocean salinity is not related to water temperature.
Ocean salinity changes with depth at a steady rate throughout the entire water column.
Ocean salinity increases as ocean temperature decreases.
Ocean salinity is more stable at higher temperatures than at lower temperatures.
Answer:
Ocean salinity increases as ocean temperature decreases.

If an atom contains one electron and one proton, will it carry any charge or not?
Answer:
An electron is a negatively charged particle, whereas a proton is a positively charged particle. The magnitude of their charges is equal. Therefore, an atom containing one electron and one proton will not carry any charge. Thus, it will be a neutral atom.
Answer:
That atom will not contain any charge because one negative charge of single electron and one positive charge of single proton are neutralized by each other.

the process where maiten magma rises and sinks due to tempature of difference, CRIVNCONEO
Answer:
Convection
Explanation:
The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.
This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.
Hence, in this case, the correct answer is CONVECTION

Which of these is NOT an interaction between a plant's root and shoot systems?
The roots absorb water from the soll to prevent leaves from drying up.
The phloem transports sugars from the leaves to the root nodules for storage.
Nutrients are absorbed from the soil and moved to the stems.
The stomata open to allow carbon dioxide to enter the leaves.
I
Answer:
The stomata open to allow carbon dioxide to enter the leaves.
Explanation:
Higher plants are made up of two major system parts namely: shoot system and root system. The shoot system constitutes every part of the plant above the ground i.e leaves, fruits, stem etc. while the root system constitutes the part below ground i.e the roots. The shoot system and root system, however, interacts in several ways to ensure that the plant functions optimally. The ways they interact include:
- The roots (root system) absorb water from the soil, which is transported upwards to prevent leaves (shoot system) from drying up.
- The phloem, which is a conducting tissue, transports sugars (product of photosynthesis) from the leaves (shoot system) to the root nodules (root system) for storage.
- Nutrients are absorbed from the soil by the roots (root system) and moved to the stems (shoot system).
Note that, although it is true that "stomata in the leaves open to allow carbon dioxide to enter the leaves", there is no connection between the shoot and root system.
Answer:
the first choice is D) The stomanta open to allow carbon dioxide to enter the leaves.
