Traits and Reproduction, please help!
Answer:
They create models of genes, proteins, and traits. In sexual reproduction, each parent randomly passes on one of its two copies of each gene to its offspring. ... Each offspring can inherit a different combination of gene versions, so siblings can have different traits from each other and from their parents.

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.

What is the most valid conclusion regarding ocean salinity based on the data?
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.

The scale below shows the pH levels of various liquids. pH scale showing ammonia (11.6), sea water (8.3), pure water (7), vinegar (2.5), and battery acid (1) pH scale showing ammonia (11.6), sea water (8.3), pure water (7), vinegar (2.5), and battery acid (1) Which of the following substances is a strong acid? Choose 1 answer: Choose 1 answer: (Choice A) A Ammonia (Choice B) B Sea water (Choice C) C Battery acid (Choice D) D Pure water
Answer:
Battery Acid
Explanation:
Since Battery Acid is closest to 0 on the pH scale, it is very acidic, and of the other choices, the most acidic.
Battery acid is the most acidic from all of the following substances.
What is pH and strong acid?pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. A strong acid is one that completely ionizes (dissociates) in a solution.
pH is a measure of how acidic/basic solution is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. now battery acid is 1 which indicates it is strong acid among all of them.

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.

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.
