How does water depth affect marine life

Biology
1 answer:
mixas84 [53]3 years ago
7 0

Answer:

At deep-sea depths, the pressure is unimaginable, yet many creatures have no problem living there. ... Deep-sea pressures do affect chemical reaction rates somewhat, speeding up reactions. Organisms adapted to these pressures may experience metabolic problems when brought to the surface for study.

Explanation:

Answer:

The cell cycle is the life cycle  

16

They lack nuclei, so prokaryotes do not undergo mitosis.(instead they preform binary fission)

The cell produces organelles during _____I don't know how to answer this. While the answer is G2phase of interphase that wouldn't result in two diploid cells you would have to specify that mitosis produces two cells  

results in the formation of two new cells.

I hope I was somewhat helpful

What is a gene?

  • According to Mendel something was being stably passed down, unchanged, from parent to offspring through the gametes, over successive generations. He called these things as ‘factors’ now called as genes. Genes, therefore, are the units of inheritance.
  • They contain the information that is required to express a particular trait in an organism.
  • Genes which code for a pair of contrasting traits are known as alleles, i.e., they are slightly different forms of the same gene.
  • There is no ambiguity that the genes are located on the DNA, it is difficult to literally define a gene in terms of DNA sequence.
  • The DNA sequence coding for tRNA or rRNA molecule also defines a gene. A cistron is defined as a segment of DNA coding for a polypeptide, the structural gene in a transcription unit could be said as monocistronic (mostly in eukaryotes) or polycistronic (mostly in bacteria or prokaryotes).

What are the different structures and functions of roots?
seraphim [82]

Different structures and functions of roots

Explanation:

Roots are the underground descending non-green part of the plant.

Root functions: Anchorages the plant to the soil, absorbs water and nutrients from the soil.

Characteristics: Positively geotropic and hydrotropic, negatively phototropic; does not have nodes, internodes or stems.

Types:  

  • Tap root
  • Adventitious root – fibrous, foliar and true adventitious roots

Structure and functions:  

  • Root cap or Calyptra: Cap-like structure covering the root tip .
  1. Function: protects the meristematic tissues of the root, secretes mucilage which enhances the root tips to grow into the hard soil.
  • Meristematic zone or growing point  sub-terminal behind root cap. These cells are inverted and looks like a dome.
  1. Function – helps in the root growth by adding new cells to the root tip and other basal regions
  • Zone of elongation behind the meristematic zone.
  1. Function – helps in elongation of the root
  • Root hair zone: This is the zone of differentiation where cells differentiate into vascular tissues like phloem, xylem, endodermis, cortex etc.
  1. The main function of root hair is to increase the total surface area of root to facilitate more absorption of water and other nutrients from the soil
  • Zone of maturation: the major and mature portion of a root.
  1. Function  - lateral roots originates from this zone and radial differentiation leads to secondary growth.
