Each cell only expresses a small portion of its genes at any given time. Not synthesizing unused proteins allows resources and energy to be conserved. This understanding best supports which of the following statements?
Cells randomly express different genes
Gene expression is a regulated process
Cells cannot express certain genes
Unexpressed genes are never useful
Answer:
(B)-Gene exspression is a regulated process
Explanation:
Its right I just took a test on it.
Life cycles recycle matter and help to create balance on Earth because
Producers gain energy from the sun. Consumers gain energy from producers. Decomposers gain energy from dead consumers and
recycle it back to producers.
Living organisms are dependent on other living organisms to survive.
Producers make their own food. Consumers gain energy from producers. Decomposers break down dead matter into essential
nutrients that are then reused by producers.
Answer:Living organisms are dependent on other living organisms to survive
Explanation:
If in the second generation you still got some white flowers, what should you do next to get a colored pure-bred plant?
a. Nothing, there is no way to get a purebred from this experiment.
b. Choose several of the colored flower plants, self-fertilize them, then plant and grow the seeds.
c. Choose several of the white flower plants, self-fertilize them , then plant the seeds. If you get colored offspring you know that they are purebred.

how are photosynthesis and cellular respiration is important for our survival?
Answer: Photosynthesis and cellular respiration is important for our survival because our food chain is all reliant on plants. photosynthesis is how plants get energy and food from the sun. whether you eat plants or meat from farm animals, that energy all goes back to plants and the process of photosynthesis.
Explanation:
What is the difference between plantlike protists and funguslike protists
Answer:
One is a plant and the other is a mushroom.
Explanation:
Can one of you help me please
Answer:
Glucose
General Formulas and Concepts:
Biology - Cellular Respiration
Cellular Respiration CycleCellular Respiration Reaction: C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + energyExplanation:
According to the Cellular Respiration Reaction, our reactants are glucose and oxygen and our products are water, carbon dioxide, and energy.
Therefore, the only answer choice that fits is "glucose".
Direct observation is the simplest and most effective method to determine population size
Please select the best answer from the choices provided
OT
F
Answer:
El statement that say Direct observation is the simplest and most effective method to determine population size is false.
Explanation:
Simple observation results in an inadequate method for estimating the size of a population, especially if it is very large and mobile. A simple and adequate method consists of counting individuals within a population, with some limitations.
Currently, in large populations, it is common to divide an area occupied by a population into quadrants, count individuals, and then extrapolate the data to the actual dimensions of the space occupied by that population.

Which characteristic is shared by telophase and anaphase?(1 point)
A The nuclear membrane dissolves.
B The two nuclei are formed.
C The sister chromatids move.
D The mitotic spindle is formed
Answer:
B The two nuclei are formed.
Explanation:
This question is describing the processes involved in MITOSIS, a kind of cellular division. Mitosis, however, takes place in steps
In both anaphase and telophase, the movement of sister chromatids takes place.
• A phenomenon in which a single cell differentiates into two similar daughter cells is termed as mitosis.
• Mitosis takes place with precise steps and regulation.
• The dissolving of the nuclear membrane takes place in the prophase phase of mitosis.
• The formation of two nuclei takes place at the telophase stage of mitosis.
• The formation of mitotic spindle takes place at the metaphase stage of the mitosis.
• In the anaphase, the sister chromatids or the chromosomes are pulled towards the opposite poles, and in telophase the sister chromatids or the chromosomes arrive at the opposite poles, thus, in both anaphase and telophase, the movement of sister chromatids is taking place.
Thus, the correct answer is option C, that is, the sister chromatids move.

The following cells is the ___ stage of ___
Answer: Telophase, mitosis
Explanation:
The following cells is the telophase stage of mitosis. We can see that in the picture because we can see parts such as the Contractile ring(which is in the middle), Complete nuclear envelope, Decondensed chromosomes, and Centrosome.
This is considered as the final or also called the fifth process in which the cell is getting separated and it is duplicating genetic material that is carried in the nucleus.
