In the amoeba, water input and output are controlled by the _____.

1 answer:

7 0

<span>Amoeba obtain nutrition by holozoic mode. It engulfs food, which remains iside the vacoule where digestion takes place. Vacoule move inside and fuse with lysosome, which releases proteases and amylase for digection of the engulfed food. The digested food is absorbed by the cell. Undigesed food remains in the vacoule, which fuses with cytoplasmic membrane and ruptures to throw the excreta.</span>

Why do you think sometimes the skeletal and muscular systems are combined to be called the Musculoskeletal System?

KonstantinChe [14]

Answer:

Musculoskeletal System is the system of the body which perform the important function of the body like helps in the movement of the body, provide the shape and support to the body.

The system is formed by two different systems of the body which are the skeletal system and the muscular system.

The skeletal system protects the internal structure of the body but the muscular system which are attached to the skeletal system and increases the efficiency of the functions performed by the skeletal and muscular system. Both of this system work together to perform the same functions.

The ischemic penumbra can maintain metabolic demand with marginal blood flow from collateral circulation for a maximum of _____

likoan [24]

<span>The ischemic penumbra can maintain metabolic demand with marginal blood flow from collateral circulation for a maximum of 50% before increasing in size. A penumbra is the area where the flow of blood at about 25 - 50% can maintain normal metabolic demands for 6 - 8 hours only. When it continues to increase, the human cells will die and other neurological activity will be suspended causing the person to die slowly.</span>

What is occurring during the s phase of the cell cycle?

Ghella [55]

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Select the three correct answers.

loris [4]

Answer:

a, b, c are correct

Explanation:

Enhancers are DNA sequences that increase the rate of transcription. Enhancers act as binding sites for transcription factors that stimulate the transcription of one or more genes and enhancers stimulate transcription for specific cell type or tissue in a specific manner. The possible reasons for the lack of enhancers in bacteria include.

Enhancers often provide a mechanism for cell-specific transcription of genes, and most bacteria lack differentiated cell types.

Bacterial operons make coordinate regulation of protein synthesis by enhancers unnecessary.

There is little to no intergenic space on bacterial chromosomes, which makes long-range-acting enhancer sequences unnecessary.

Therefore, the correct options are (a), (b), and (c).
