Frigid temperatures, etc.

Explanation

The tundra has very low temperatures and a layer of permafrost over the soil. It has characteristics similar to the desert and it also has a short summer and a long, freezing winter. Therefore, there are not many flora variations that can thrive in that biome.

Answer:

The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.

Answer:

As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

Answer:

Pink

Explanation:

Incomplete dominance is when one allele is not entirely dominant over the other. The resulting phenotype of the heterozygote is intermediate between the two alleles. That means the flowers would be pink.

Red  - no, this would be true if red was dominant to white

Pink  - yes, this is an intermediate phenotype

White  - no, this would be true if white was dominant over red.

Red and White  - no, this would be true if the alleles were co-dominant and both equally but independently expressed.

Answer:

The correct answer is - 50%.

Explanation:

Codominance is a type of inheritance that takes place when the genotype of an individual organism in heterozygous condition express traits of both alleles.

Cross between blue and white pigeon and pure white:

BW × WW and gametes will be B and W and W and W

     B         W

W   BW     WW

W    BW     WW

There are 50% of BW that is blue and white pigeons

Answer: C. The warm surface currents help create storms and fog.

Explanation:

The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

Answer: The Sun

3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Explanation:

Answer:

The main energy source for life is the Sun

Explanation:

NAD +molecule

Explanation:

Krebs cycle and electron transport chain are important steps in cellular respiration.

In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.

NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.

Now in the Krebs cycle, it is ready to take electrons again.

Answer:

NAD+

Millimeters allow for the most accurate measurement.

A paper clip may be measured with both units (millimeter or centimeter) but a millimeter is the greater appropriate size to get an accurate measurement.

A ruler marked in millimeters is extra unique than a ruler marked best in centimeters, considering a millimeter is a smaller unit than a centimeter.

Answer:

A. If seed shape did not have a clearly recessive form

Explanation:

To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.

For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.

Answer:

A. If seed shape did not have a clearly recessive form.

Answer:

Mainly because Evolution takes millions and millions of years to happen.

Explanation:

Evolutionary theory require earth to be very old because the process of evolution takes millions of year to happen.

Evolution is the process through which a population of organisms evolves as new generations replace ancestors. Individual species do not evolve; rather, communities of organisms do.

Natural selection processes like as environmental change, predation, or human disturbance create evolutionary adaptations, and these processes must continue and grow widespread for the change to remain and accumulate. That happens less frequently and slowly than you may expect.

Scientists have determined that Earth is 4.54 billion years old, with a 50 million year error, by dating the rocks in its ever-changing crust as well as those in Earth's neighbors, including the moon and passing meteorites.

Therefore, the Earth needs to be very old for evolutionary theory to be true.
