A magnified cross-sectional view of a horsetail stem shows the tube-shaped cells of xylem. What is their function?

1 answer:

5 0

The xylem is the structure of the plant that is responsible for transporting water from the ground up to the different parts of the plant. It is composed water, inorganic ions, and a number of organic chemicals.

Xylem tissue is found throughout the plant because not only does it transport water, but it also transports the nutrients that the plant needs for different processes. Aside from being responsible for the transportation of materials, the xylem is also used to replace water that was lost during photosynthesis and transpiration.

a. replicate DNA at the appropriate time.

Prokaryotes are one celled organism that only reproduce by binary fission. A copy of a copy, of course the DNA is copied as well. DNA is duplicated a succinct period of time when necessary since the energy needed to perform this process is necessarily abundant.

Which of these is the primary site of protein synthesis? mitochondria cytoplasm nucleus ribosomes

Murrr4er [49]

Answer:

A. Ribosome

Explanation:

Ribosome is a sub cellular structure, that is involved in protein synthesis.

Mitochondria is a sub cellular structure, where cellular respiration takes place, therefore it is called the energy house of the cell.

Cytoplasm is a jelly like structure in which sub cellular structures are found.

Nucleus is the main part of the cell in which all cellular activity is controlled by.

It contains DNA and RNA.

Nucleus is mostly known for it's thread like structure that contains hereditary information which is passed from parents to offspring.

Hope it helps ;) ❤❤❤

Answer:

5' GCGATT

Explanation:

Complementary sequence: Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

the eastern kingbird hunts by catching flying insects in mid-air, an approach which requires impressive and energetic acrobatic

tangare [24]

It is safe to assume that the eastern kingbird will have a type 2 functional response to an increase in prey abundance.

The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:

Type 1: An increase in consumption
Type 2: A decrease in consumption
Type 3: Decreased consumption, followed by a quick increase.

The Eastern kingbird is likely to follow a type 1 functional response to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
