do dicot and monocot leaves have different adaptations?

Answers

Answer:

Yes. Monocots have leaves with parallel venation, and dicots have leaves with reticulate, net-like venation. Describe an example of a plant with leaves that are adapted to cold temperatures. Conifers such as spruce, fir, and pine have needle-shaped leaves with sunken stomata, helping to reduce water loss.

Halfway through exponential phase, the temperature is lowered slightly below the
optimum. How will the growth curve change?

A. The cells will immediately enter death phase

B. The cells will enter lag phase

C.The slope of the exponential phase will become shallower

D. The slope of the exponential phase will become more steep

Which one is the best answer ? Choose only one answer

Answers

Answer:

B. The cells will enter lag phase

Explanation:

There are four identifiable phases of bacterial growth in a culture. These are: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.

The lag phase occurs when there is need for the growing bacterial cells to adapt to new conditions.  The adaptation period, i a time when the cells  adjust themselves to the new conditions. The length of the lag phase varies considerably, depending on the initial and final conditions of  the bacteria cells.

Hence, when the temperature is slightly lowered below the optimum halfway into the exponential phase, the cells will enter into lag phase

White blood cells called B cells produce proteins that can be used for the treatment of certain illnesses. However, these B cells do not live for very long on their own. To keep the B cells growing for a long time in laboratories, scientists fuse the B cells with cancer cells (fused B-cancer cells) that do grow for a very long time. The particular cancer cells used for the fusion are treated with chemicals that make them unable to produce the nitrogenous bases adenine and guanine, but the B cells with which they are fused do produce these nitrogenous bases. The scientists grow the large fused B-cancer cells in a growth medium that contains necessary nutrients for the cells and includes a source of carbon.
(a) Describe the role of carbon in biological systems.
(b) The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
(c) Make a claim about the most immediate effect on the fused B-cancer cells if the fused cells are transferred to a growth medium that lacks a source of nitrogen.
(d) Provide reasoning with evidence based on the composition of biological macromolecules to support your claim.

Answer:
B. Used by plants to make food

Explanation:
Chlorophyll is found in chloroplasts inside of cells. It’s a green pigment and it absorbs sunlight. The sunlight that is absorbed is then used in the process of photosynthesis. Photosynthesis is used by plants, algae, and some bacteria. It produces glucose or sugar, which becomes food for the organism.

Therefore, the best choice is B. used by plants to make food.

What is the cell cycle?

Lesson Question
Help please !!!

Answers

A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle.

Which of the following statements is true about both fungi and protists

A) They can both photosynthesize
B) They reproduce by binary fission
C) Single-called organisms are found in both groups
D) Both groups are motile

Answers

I think the answer is C

The statement 'single-celled organisms are found in both groups' is TRUE (Option C).

Both protists and fungi are eukaryotic organisms, which means that their cells have the genetic material (DNA) compartmentalized in a cell nucleus and membrane-bound organelles.

Protists are single-celled microorganisms that belong to the Kingdom Protista. The protists represent a broad category of microorganisms that cannot be categorized as animals, plants, or fungi.

Moreover, fungi are organisms characterized by their cell walls, which contain chitin. These organisms are generally sessile like plants.

Fungi can be unicellular or multicellular. The unicellular fungi are known as yeasts (e.g., Saccharomyces cerevisiae).

In conclusion, the statement 'single-celled organisms are found in both groups' is TRUE (Option C).

What amino acid residue would MOST likely be buried in the interior of a water-soluble globular protein?

Answers

The group of choices associated with the question is:

Tyr-Phe-Glu-Asn-Leu

Met-Phe-Pro-Ile-Leu

Val-Ala-Val-Glu-Val

Glu-Asn-Ser-Thr-Gln

Answer:

The correct answer is - Met-Phe-Pro-Ile-Leu

Explanation:

There is various type of amino acid residues that are located in the water-soluble globular protein, depend on the location inside the globular protein, that could be the center of the particular protein or interior of the protein.

Met-Phe-Pro-Ile-Leu  is the amino acid residue among given options is the most likely the sequence as all the amino acids are nonpolar in this residue.

Thus, the correct answer is - Met-Phe-Pro-Ile-Leu

The amino acids that would be buried will be Met-Phe-Pro-Ile-Leu.

Amino acids simply refer to the organic compounds that contain amino and carboxylate functional groups. They're the molecules that combine in order to form proteins.

From the complete information, it should be noted that globular proteins are folded in such a way that their tertiary structure consists of hydrophilic, amino acids, arranged on the outside. From the options given, the amino acids that would be buried in the interior of a water-soluble globular protein will be Met-Phe-Pro-Ile-Leu.
