GAGTTA is what you have.
CTCAAT is what you’ll get.
A matches with T, G matches with C, and U is only for translating out of the DNA sequence.

One strand of a DNA molecule has the base sequence GAGTTA. The complementary base sequence on the other strand of DNA will be CTCAAT

The base pairs in a DNA(Deoxyribonucleic acid) molecule consists of 4 base sequences namely:

AdenineGuanineCytosineThymine

Each base has a complimentary base sequence which it binds to during DNA formation as it helps to make the nucleotides stable.

Adenine has a complimentary base of Thymine  while Guanine has a complimentary base of Cytosine and vice versa.

Explanation:

I had a test with this, and it was glucose.

Glucose is a reactant of both cellular respiration and dehydration synthesis

WHAT IS CELLULAR RESPIRATION?

Cellular respiration is the process by which living organisms obtain energy from organic sources.

Cellular respiration combines glucose and oxygen as reactants to form carbon dioxide (CO2), water (H2O), and energy.

WHAT IS DEHYDRATION SYNTHESIS?

Dehydration synthesis is a reaction whereby two smaller molecules come together to form a larger molecule with the loss of water.

An example of dehydration synthesis reaction is the formation of starch from the reaction of glucose molecules with the loss of water.

Therefore, glucose is a reactant of both cellular respiration and dehydration synthesis.

A disadvantage of sexual reproduction in plants is

Answers

Answer:

These are some of the disadvantages of sexual reproduction: time and energy are needed to find a mate.

hope this helps!

A disadvantage of sexual reproduction is the fact that ADDITIONAL ENERGY is required to complete a life cycle.

Sexual reproduction can be defined as a type of reproduction that involves a complex life cycle in which germinal haploid cells called gametes combine to produce a diploid (2n) cell called the zygote.

Subsequently, this zygote then divides to produce an adult organism.

In plants, the most important disadvantage of sexual reproduction is that energy is required to complete a complex life cycle (i.e., zygote development).

The diploid (2n) multicellular stage in the life cycle of a plant is known as the sporophyte.

In conclusion, a disadvantage of sexual reproduction in plants is that ADDITIONAL ENERGY is needed to complete a complex life cycle.

25. How do the excretory systems of animals that secrete uric acid differ from those of animals that excrete urine?
34. Explain why maintaining water balance is part of the process of excreting nitrogenous wastes.

thanks!!

Answers

Answer:

25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.

34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea
