What is true concerning an ecological community?

Biology
1 answer:
Ivenika [448]3 years ago
3 0

Answer:An ecological community is a naturally occurring group of native plants, animals and other organisms that are interacting in a unique habitat. Also, it is an association of populations of two or more different species occupying the same geographical area in a specific time.

Therefore, the answer is it is a large region of multiple organisms within the boundaries

<h2>Synovial fluid </h2>

Explanation:

Due to the Vroman effect, albumin will initially attach and eventually be replaced by the IgM, which has a higher affinity for the material

The higher concentration of the albumin results in a greater initial surface concentration via diffusion, but it will eventually be displaced by the proteins with greater surface affinity (first the transferrin, and finally the IgM)

If more addition of albumin occurs, which has less affinity for the material surface, will have minimal effect if IgM is already adsorbed to material surface

Bumek [7]

Answer:

K = 9.620 × 10⁻⁶

Explanation:

From the given information:

Temperature T= 6° C

= (273 + 6)K

= 279 K

The correct and well presentation of the reactions are:

1. Luciferin + O_2     ⇆     oxyluciferin + light   ΔG₁°

2. ATP                     ⇄   AMP + PP_i                  ΔG₂°  = -31.6 kJ/mol

The overall  ΔG° = -4.80 kJ/mol

Let's first determine the ΔG₁° for the equation (1)

ΔG° = ΔG₁° + ΔG₂°

- ΔG₁° = - ΔG° + ΔG₂°

ΔG₁° = ΔG° - ΔG₂°

ΔG₁° = ( -4.80 - (-31.6) ) kJ/mol

ΔG₁° = 26.8 kJ/mol

Using the formula:

ΔG° = -RTIn K

In \  K =\dfrac{-\Delta G^0}{RT} \\ \\ log \ K = -\dfrac{\Delta G^0}{2.303RT}

log \ K = -\dfrac{\Delta G_1^0}{2.303RT} \\ \\ log \ K = -\dfrac{26.8 \times 10^3 \ J/mol}{2.303\times 8.314 \ J/mol/K \times 279 \ K} \\ \\ log \  K =- 5.017

K = antilog (-5.017)

K = 9.620 × 10⁻⁶

Scientists have successfully cloned sheep and cattle for several years. A farmer is considering the advantages and disadvantages
max2010maxim [7]

Answer:

Cloning is the mechanism by which one living organism takes genetic material and produces identical copies of it. Cells, organs, chromosomes and whole species have been cloned by geneticists.

<u>The scientist need to take of some of the issues before cloning of sheep are as following:</u>

  1. Conflict with long-standing religious and social values about human dignity, probably infringing the principles of equality, identity and autonomy of each person.
  2. Cloned embryos face the same difficulties as naturally occurring pregnancies, plus others that are unique to cloning, so embryonic condition should be maintained.
  3. Cloned embryos surviving pregnancy may be born with a number of birth defects and other health issues.
  4. However, cloned cells can lack the programming required to tell the genes when to turn on and off. The outcome could be disorganised cell growth or abnormal functioning of the cell, all of which may lead to death of an organism.

kow [346]
Options are not provided in the question. I found the answer on the internet.

Answer: CPT code reported is 26010-F5
26010-F5 is a CPT code that refers to drainage of finger abscess.
F5 means right hand thumb. Since in the above question the patient presents abscess of the right hand thumb, it will be F5 and the fluid is drained so it will be 26010. So, the CPT code will be 26010-F5.
