During sexual reproduction, traits from both parents of an organism combine to form a new set of traits. For a given set of selection pressures in the surroundings of a population, the combinations of genes dictate whether the organism has favorable or non-favorable traits. Thus, natural selection is dependent on reproduction.

Why is frog egg laid in long gelatin fluid

Naya [18.7K]

Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.

Although DNA is made up of only four different bases, it can encode the information necessary to specify the workings of an enti

VLD [36.1K]

Answer:

Because DNA molecules are extremely long.

Explanation:

DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.

The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.

Answer:

Independent variable: ALTITUDE

dependent variable: GROWTH OF PLANTS

Confounding variable: STOREYS OF THE BUILDING

Explanation:

In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.

- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.

- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.

- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.

How do living things make use of the energy stored in food molecules?

ipn [44]

Answer:
The energy stored in food molecule (glucose) is released in he process of respiration.

Explanation: Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis: It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A: It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle: It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain: It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
