Which of the following is true about biofuels? a. they are made from plant materials and animal fats.
b. they are made by directly harnessing energy from the sun.
c. they use energy from water.
d. they use energy from the earth���s core.

Answers

Answer 1
Answer: It is A. they are made from planets materials and animal matter. Biofuels comes from anything that was alive. This does not include fossil fuels. Example: ethanol made from corn. A corn is a plant that is a living thing.
Answer 2
Answer:

The true about biofuels is they are made from plant materials and animal fats, that can be understand more about biofuels.

What are biofuels?

Biofuels are renewable energy sources that originate from vegetables, such as plants, seeds and fruits, which is why they are also called agrofuels. In Brazil, the main biofuel used is ethanol, but there are others such as biogas and biodiesel.

Today, the most used forms of biofuels are:

  • biogas.
  • bioether.
  • Bioethanol.
  • Biodiesel.
  • Ethanol.
  • Vegetable oil.

For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with red flowers a second parent with white flowers will have pink flowers?100%

For four o'clock flowers, flower color is a case of incomplete dominance. The gene for flower color has two alleles: red (R) and white (r). What is the percent probability that one offspring from a parent with the genotype RR and a second parent with the genotype rr will have red flowers?

Answers

Answer:

0%

Explanation:

According to the question, the inheritance pattern of flower colour in four o'clock plants follow incomplete dominance i.e. one allele is not completely dominant over the other, and instead they form a heterozygous plant with a third intermediate phenotype (flower colour).

In this case, a four o'clock plant with genotype RR will have red flowers while a plant with genotype rr will have white flowers, Hence, they cross to form an all Rr genotype offsprings with pink flowers (since the red allele is incompletely dominant). Therefore, the percentage chance of having a red flower offspring from this cross is 0%, as it cannot occur.

WILL MARK BRAINLIEST!!!! Can someone help me wit dis question? Summarize in 2-3 sentences the process of photosynthesis

Answers

Answer:

Photosynthesis is a chemical reaction where plants take in carbon dioxide (CO2) and water (H2O) through its stomata. With the help of sunlight and chlorophyll, which is found in its chloroplast, it is used to produce glucose (C6H12O6) and oxygen (O2). It converts light energy (sunlight) to chemical energy.

Explanation:

Answer:

please mark me brainlest!!

Explanation:

photosynthesis, plants take in carbon dioxide  and water from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and conversion of CO2 into carbohydrates (carbon fixation).

Ecosystems with greater biodiversity have an increased stability.True or false?
I say true. :)

Answers

It is true that ecosystems with greater biodiversity have greater stability.

What is biodiversity in an environment?

  • It is a variety of species.
  • It is a very large number of different living beings.

Biodiversity refers to an abundance of living beings of different species and different impacts on nature. These organisms create a great environmental balance, as they act in the environment in different ways, keep the food chain stabilized, and establish a harmonious and well-structured environment.

Biodiversity is also important for the maintenance of the ecosystem as a whole, as it prevents excesses and shortages of resources, allowing all species to have everything necessary for their survival and control.
