C. Bumblebees eat the nectar
from flowers and then spread the flower pollen
D. Mountain goats evolved hooves that spread apart and have pointed edges in front so they can climb and live on steep cliffs
Answer:
C.
Explanation:
In the context of evolutionary biology, coevolution refers to the evolution of at least two species, which occurs in a mutually dependent manner. ... An example is the coevolution of flowering plants and associated pollinators (e.g., bees, birds, and other insect species)

Which property of water allows water to be resistant to sudden temperature changes?
choose 1 answer:
-density
-surface tension
-high specific heat capacity
-adhesion
Answer: density
Explanation:
Water's high heat capacity is a property caused by hydrogen bonding among water molecules.
Answer:
High specific heat capacity
Explanation:
Water has a high specific heat capacity, which means that it requires a lot of energy to raise the temperature of water.

how is gene related to allele
Answer:
Alleles are also genetic sequences, and they too code for the transmission of traits. An allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent.

the water in the solution moves into the plant cell.
the water in the solution moves out of the plant.
the solutes in the solution have a higher concentration than the solute concentration inside the plant cell.
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell.
the water is moving down its concentration gradient from high to low. the water is moving down its concentration gradient from low to high.
Answer:
The correct answer is -
the water in the solution moves into the plant cell
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell
the water is moving down its concentration gradient from high to low.
Explanation:
The hypotonic solution consists low concentration of solutes and a higher concentration of water as compared to the concentration of solutes and water of other solutions or cells. Water tends to move from a higher concentration of water to a lower concentration of water therefore the cell swell and then ultimately burst.
Water movement in such conditions is known as the movement down the concentration gradient as it moves from its higher concentration to a region of its lower concentration.
What is the role of operons in prokaryote gene expression?
Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.
What is operon?Operons are frequently found in bacterial genes. An operon is a collection of genes that all share a single promoter during transcription.
There are regulatory DNA sequences in every operon, and these sequences serve as binding sites for regulatory proteins that either encourage or inhibit transcription. Genes involved in lactose metabolism are found in the lac operon of E. coli. It only expresses itself when lactose and glucose are both absent.
A lactose sensor is the lac repressor. When lactose is present, it ceases to function as a repressor, blocking transcription of the operon in its usual state. Through its isomer allolactose, the lac repressor indirectly detects lactose.
Therefore, Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.

how does our water use affect the bay-delta ecosystem?
Answer:The Sacramento-San Joaquin Rivers Delta and San Francisco Bay (hereinafter “Bay-Delta”) is an important economic and environmental resource benefitting all of California and the nation. The Northern California Water Association (NCWA) and Sacramento Valley water resources managers recognize the importance to California’s future of a healthy Bay-Delta and providing high quality and reliable water supplies for all beneficial uses. For the past several decades, NCWA has been a strong and constructive participant in the various processes designed to help solve the challenges in the Bay-Delta. We will continue to play a constructive role in implementing necessary solutions to Bay-Delta problems, as long as the actions do not affect the ability to serve water for multiple beneficial uses in the Sacramento Valley, including cities and rural communities, fish, farms, birds and recreation.
NCWA and Sacramento Valley water resources managers have supported the state’s co-equal goals–providing a more reliable water supply for California and protecting, restoring and enhancing the Delta ecosystem–and have encouraged success in Voluntary Agreements as a new way forward in California.
4. Which of the following does not make up a bronchi?
a. cartilage
c. smooth muscle
b. mucous lining
d. pleural membrane
Answer:
c. smooth muscleExplanation:
The cartilage and mucous membrane of the primary bronchi are similar to that in the trachea. As the branching continues through the bronchial tree, the amount of hyaline cartilage in the walls decreases until it is absent in the smallest bronchioles. As the cartilage decreases, the amount of smooth muscle increases.

Max has been assigned a science fair experiment and must research a topic related to photosynthesis . After looking at the equation for photosynthesis he notices light is listed as shown below :
Photosynthesis Respiration: 6 CO 2 (Carbon dioxide) + 6H20 (water) ➡️(Light)(Chlorophyll) C 6 H 12 O 6 (sugar) + 6O 2 (Oxygen).
Max chooses to explore the effects of light on plant growth . He places three sunflower seedlings in three separate pots . He allows them to grow for 2 weeks and measures the growth of each plant . The pot that was placed in his basement , where no light reaches , grew 2 cm . The plant in his kitchen was a few feet away from a window that allowed some light in . The plant in the kitchen grew up to 20 cm . Last of all , the third pot which sat directly in the windowsill grew up to 30 cm .

Different types of cells can have certain organelles and structures in common. Which types of cells definitely contain cell walls?
SC.912 L 14.3
O plant and animal cells
0 plant and eukaryotic cells
o plant and prokaryotic cells
animal and eukaryotic cells
Answer:
plant and eukaryotic cells (B)
Explanation:
animal cells have a cell membrane but no cell wall and prokaryotic organisms lack a nucleus or any other membrane bound cell organelle.
Plant and prokaryotic cells definitely have a cell wall. So, the correct option is C.
What is Cell wall?Cell wall is defined as the structural layer that consists of polysaccharides and is present outside the plasma membrane which can be rigid, rigid and flexible. This provides protection to the cell from external factors that may be harmful to the cell and also provides structural support.
Plant and prokaryotic cells definitely have a cell wall. The cell wall of a prokaryotic cell is present under the capsule while the cell wall of a plant cell is a specialized form of extracellular matrix that surrounds each cell of a plant. This provides structural support to the cell and protects the cell against infection and mechanical stress
Therefore, the correct option is C.
