Answer:
a. glucose molecules move agnst the concentration gradient across the cell membrane w the help of atp
Explanation:
active transport requires energy (atp) to push a molecule agnst its concentration gradient
also glucose molecules r too large to cross without the help of transmembrane proteins
and oxygen molecules r able to get thru by simple diffusion bc they r small enough
Glucose molecules move against the concentration gradient across the cell membrane with the help of ATP is an example of active transport.
Active transport is a biological term to refer to the movement within the cell in which some molecules move across the cell membrane. This movement requires energy from cells to move.
According to the above, when a glucose molecule moves against the concentration gradient across the cell membrane and in this movement it consumes energy (ATP) it is carrying out active transport.
According to the above, the correct answer is A. because it exemplifies active transport.

Which organelle turns solar energy into chemical energy? Question 1 options: Golgi Apparatus Endoplasmic Reticulum Chloroplast none of the above
Answer:
Structure of the Golgi bodies in a plant cell. A typical plant cell organelles include Cell wall, Cell membrane,converts water, carbon dioxide, and light energy into nutrients for lack the chloroplast pigments, they are found in non-photosynthetic parts
Explanation:
The organelle that turns solar energy into chemical energy is chloroplast. The correct option is C.
Chloroplasts are organelles that may be found in plant cells and some types of algae. They are in charge of the process known as photosynthesis, which transforms solar energy into chemical energy.
The chlorophyll pigment in the chloroplasts absorbs sunlight and transforms it into chemical energy in the form of glucose via a series of intricate processes.
This process is the main method by which solar energy is transformed and stored in living organisms, and it is essential for the synthesis of food and oxygen in plants. Chloroplast is the right response as a result.
Thus, the correct option is C.

Rb is an important protein for controlling cell proliferation by blocking entry into S phase. How does it exert its effect?
Answer:
The main function of the RB protein is to inhibit the transition from the G1 to S phase. Its activity depends on its phosphorylation state: if RB is not phosphorylated (active state), it is bound to the transcription factor E2F, preventing its translocation to the nucleus and the activation of genes necessary for DNA synthesis; and if it is phosphorylated, by cyclin-CDK complexes, E2F is released and cell proliferation occurs.
Explanation:
Retinoblastoma (Rb) was the first tumor suppressor described and, as we know today, mutations in its structure determine a large number of cancers. Structurally, we speak of a large and multifunctional protein; which is organized in different domains. The activity of this protein is regulated, mainly, by phosphorylation at multiple sites described over the years and is involved in control mechanisms of the cell cycle, apoptosis and senescence.

What causes a protein to be released from the ribosome
Answer:
The release factors cause the ribosome peptidyl transferase to add a water molecule to the carboxyl end of the most recently added amino acid in the growing polypeptide chain attached to the P-site tRNA. This causes the polypeptide chain to detach from its tRNA, and the newly-made polypeptide is released.
A stop codon causes the ribosome to separate from the mRNA molecule and release the protein for the cell to utilize. The relationship between transcription (DNA to mRNA) and translation (mRNA to protein) in prokaryotic cells is so strong that.
What protein to be released from the ribosome?The ribosome peptidyl transferase adds a water molecule to the carboxyl terminus of the most recently added amino acid in the expanding polypeptide chain connected to the P-site tRNA as a result of the release factors.
Protein release factors (RFs) recognize stop codons located in the A site of the small ribosomal subunit and initiate peptide release to the ribosome.
Therefore, As a result, the freshly produced polypeptide is released and the polypeptide chain separates from its tRNA.

A. No new rock is created just smaller in size. B. A new rock is produced that is different from the original rock. C. A new rock is produced that is the same as the original rock. D. A new rock is produced that is larger than the original rock
Answer:
A new rock is produced that is different from the original rock.
Explanation:
During chemical weathering, a new rock is produced that is different from the original rock.
Chemical weathering is the chemical decomposition of rocks to form sediments and soils. A large chunk of rock combines with water, air and other chemical materials. This cause chemical action and a new substance is produced. This process is known as chemical weathering.Physical weathering is the breaking down of rocks into smaller fragments.
Chemical weathering leads to the formation of a new rock is produced that is different from the original rock that has undergone chemical weathering is formed.

which do you prefer to use organic fertilizer or inorganic fertilizer explain
Answer:
Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.
