12. Flowers whose reproductive structures consist only
of stamens would be able to produce
A) fruits with seeds
B) fruits without seeds
C) pollen
D) ovules
Answer:
Pollen reproductive structures consist only
of stamens would be able to produce
Explanation:
No C is the answer
Reproductive structures are structures that make up the reproductive organs of a particular organism. These structures could include either female or the male reproductive organs.
Flowers with reproductive structures that comprise of only stamen would produce only pollen (option c).
Stamens are reproductive organs found in plants and they are male reproductive organs. For fruits with seeds to be formed the male and female reproductive organs must come together to produce a fruit.
Flowers with only the stamen will produce only pollen which is a male gamete that needs to be joined to the female gamete, ovary produced from the female reproductive structure (pistil) in a plant to produce a fruit.

What must the pea and lettuce plants take up through their roots to perfum photosynthesis
Answer: The pea and lettuce plants are leguminous plants.
Explanation:
The pea and lettuce plants must take nitrogen from the soil which they get after the symbiotic association with the nitrogen fixing bacteria. Nitrate and ammonia are the two components of nitrogen that can be taken from the soil and used as a source of nitrogen. Nitrogen is required for the growth of plant and it is the important component of chlorophyll pigment. Chlorophyll pigment is necessary for the process of photosynthesis in which the chlorophyll pigment traps sunlight energy that is involved in the splitting of molecule of water into hydrogen and oxygen.

Do plants and animals use cellular respiration to generate energy?
A. Yes
B. No
Answer:
yes
Explanation:
This cellular respiration is carried out by every cell in both plants and animals and is essential for daily living. Cells use glucose and oxygen to produce yg p carbon dioxide, water, and energy. In cellular respiration, the carbohydrates from food are disassembled into glucose molecules.
Plants undergo cellular respiration.
Animals don't need to photosynthesize since they get their glucose from the food they eat. Cellular respiration is not simply the same as "breathing." This can be confusing! People often use the word "respiration" to refer to the process of inhaling and exhaling.
Answer:
A. Yes
Explanation:
Yeah, the plants and animals use cellular respiration to generate energy. So, option (A) is correct answer.

What is the current to the following DNA strand TATTAGATTACA
Answer:
ATAATCTAATGA
Explanation:
Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. DNA has four nucleobases: adenine, thymine, guanine, and cytosine. The nucleobases in a DNA strand have preferred partners to form hydrogen bonds with. Cytosine pairs with guanine, and adenine pairs with thymine. These are the base pairing rules that allow DNA replication and protein synthesis to happen.

B. Mutualistic
C. Predator-Prey
D. Parasitic
Answer:
C. Predator-Prey
Explanation:
There are predator-prey relationship between ants and antlions.
The type of relationship between the ant and ant lion is Predator-Prey. The correct option is C.
What is predator-prey relationship?Predator-prey relationship implies to the interactions among the two species where one species is the killed food resource for the another one.
The organism that feeds is referred to as the predator while the organism that is fed upon is basically the prey. There are mainly most variety of illustrations of predator-prey relations.
Competition as well as predation are ecological interactions but are not symbiotic.
Predation usually does not take place over a long period of time, along with the competition is an indirect interaction on other resources.
Predation is a symbiotic interaction in which one species sustains life on costuming the another species.
The species that win is the predator, and the species that is lost up is the prey.
Thus, the correct option is C.
