The sun is a source of energy for all living things.

Sergio039 [100]3 years ago

Answer:

The sun.

Explanation:

Sun is the ultimate source of energy. All living things on the earth using the energy comes from the sunlight.

Plants using sunlight to fuel the process of photosynthesis. Photosynthesis is the process of transforming of water and carbon dioxide to oxygen and glucose. The amount of energy used to drive the photosynthesis process is stored in the glucose molecules.

Organism feed on plants and breaking down the glucose molecules to release the stored energy. The release energy is utilized by the cells present in the organisms.

Autotrophs also have the ability to make their own food, so they are also using the energy from the sun to make their food.

P (purple) and p (white) are the dominant and recessive alleles for flower color in peas. Similarly, A (axial) and a (terminal)
butalik [34]

Answer:

Option C, ppAa is indicative of white axial flowers.

Explanation:

It is given that Purple color (P) is dominant over white color (p). Thus in order to have a flower of white color , the flower must be homozygous recessive with an allele pair having two recessive alleles.

Similarly, Axial (A) is dominant over terminal (a) flower. Thus, a flower can be axial in two cases -

a) when both the alleles are same i.e AA

or

b) when one allele is A and the other one is a i.e Aa

Considering the above cases, all possible allele combination that will produce white axial flower are as follows -

ppAA, ppAa

Thus, option C is correct

Which causes the biodiversity of rainforests?
sashaice [31]

Answer:

B. Stable ecosystems

Explanation:

The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.

A stable ecosystem is a sustainable one that does not change too much over the course of time.

Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.

  • Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here.
  • This suggests that the producers have enough energy to cater for their own need and that of the organisms there in.
  • The consumers and decomposers have sufficient food available all year round.
  • This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms.
  • An unstable ecosystem cannot be biodiverse

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.
