Answer:

1) Growth Pattern

2) Conical Shape

3) Needle-shaped leaves

4) Pine needles

5) Waxy coating

6) Chemicals

7) Dark-colored needles

8) Thick bark

9) Ever growing roots

10) Small surface area of pine needles

Explanation:

Pinus plants are coniferous plants that are evergreen and long lived. They are usually found in the Northern Hemisphere and few parts of the Southern Hemisphere. Their adaptations include;

1) Growth Pattern: Pinus plants grow very closely to each other, creating a dense setting that helps to preserve warmth.

2) Conical Shape: Their conical shape helps them shed off snow and helps them produce enough food through photosynthesis by staying green all year.

3) Needle-shaped leaves: This helps reduce moisture loss.

4) Pine needles: This reduces moisture loss through transpiration.

5) Waxy coating: The waxy coating of their pine needles protect them from harsh weather like drying winds. It also protects them from sap that cause may freeze.

6) Chemicals: The chemicals present prevent wildlife from eating them.

7) Dark-colored needles: This helps them absorb heat from the sun

8) Thick bark: Protects against cold

9) Ever growing roots: Their roots do not stop growing even in winter so there is always moist and nutrients.

10) Small surface area of pine needles: Their small surface area helps in moisture retention.

Increased keystone species

Explanation:

An organism is a keystone species when it contributes to the definition of a given ecosystem such that the absence of the keystone species in an ecosystem, the ecosystem will change dramatically or be gradually wiped out

The effect of the keystone on its environment is unevenly large when compared to its abundance relative among other organisms within the ecosystem

The keystone is therefore, a prime source of balance of nature, diversity and well-being of the ecosystem

Therefore, the option that contributes to the diversity of the ecosystem is;

Increased keystone species.

Answer:

GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.

Are they an equation or expressions?

Solution -

1.

An expression containing variables,  numbers, and  symbols.

An equation that has equal to sign.

a.)

5x - 3 = 12

It is an equation (because it has = sign)

b.)

6x - 3

It is an expression

c.)

7x + 5 = 9

It is an equation (because it has = sign)

2.

Variable is those whose values can be change. For example x, y, z...

Constant term whose values are fixed. For example 10, 4, 5

Numerical coefficient are the constants that placed just before the variable. For example in 4x- 4 is the variable coefficient.

a.)

5x-3=12

5 is Numerical Coefficient

12 and -3  is constant term

x is variable

b.)

6x-3

6 is Numerical Coefficient

-3  is constant term

x is variable

c.)

7x+5=9

7 is Numerical Coefficient

9 and 5  is constant term

x is variable

Explanation:

Parallel circuit are those types of circuits in which break in one branch does not prevent the flow of current in the circuit and the current can still flow through another branch because there are more ways through which the current moves to other sources while on the other hand, series circuit refers to those circuits in which break in one branch can prevent the current flow in the circuit and the other sources can't receive current due to broken of the connection.

Explanation:

Codominance is a condition observed in the inheritance of coat color in the horse. The offspring of the cross between white coat male horse and brown coat female horse is mixed white and brown cats. Thus, the correct option is C.

Codominance is a non-mendelian inheritance. It is an exception of Mendelian inheritance. It is a heterozygous condition in which both the alleles present at a gene locus are fully expressed in the phenotype of an organism. Alleles which show an independent effect are called as Codominant alleles whereas in Mendelian inheritance, one allele is dominant over the other allele which is recessive. In codominance, neither phenotype is completely dominant over other.

In the cross between a male horse with white coat and a female horse with brown coat, the coat color of the offspring produced will be a mixture of white and brown coat color.

Therefore, the correct option is C.

Explanation:

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.

Every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.

There are numerous ecosystems on Earth, each with its own set of functions and living forms, but these are essential for human survival as they support a wide variety of plant and animal species, thus maintaining the biodiversity of the earth. By absorbing and storing carbon, forests, oceans, and wetlands help to regulate the earth's climate by managing the carbon cycle and regulating the climate.

Hence, every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.

Answer:

When a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron, an ionic bond is formed.

Explanation:

The bonds which are produced between a metal ion and a non-metal ion are termed as ionic bonds. Sodium is metal while chlorine is a non-metallic element, ionic bonds are formed in between them.

Sodium has one electron in its outer most shell whereas a chlorine atom has seven electrons in its outermost shell. To become stable, sodium donates its electron to the chlorine atom and hence ionic bond is formed between them.

Answer:

1. Station B

Station B has one of the lowest temperatures of 32°F(top left) which is a temperature that snow can form at. It also has full cloud cover which is something that station C does not have and as clouds are needed for snow, station B is most likely to have snow.

2. Station A

Station A has the highest dew point at 75 (bottom left) which means that it has the highest humidity and so is the most likely to have rain. That along with a full cloud cover (shaded circle), means there are clouds for rain to fall from.

3. Station B

Has the highest pressure at 998.

4. Station C

Wind speed is measured by the lines protruding from the circle and for this simplistic model, the more lines it has, the faster the wind is going. Station C therefore has the fastest wind speed.
