Answer:

Explanation:

First of all, we need to know that prokaryotes are cells that don't have true nucleus, nor membranes organelles. Its counterpart is eukaryotic cells.

<u>Characteristics of prokaryotes:</u>

  1. Lack an organised nucleus. as we said before, and membrane organelles.
  2. The central part of this type of cell is called Nucleoid, there's found its DNA.
  3. Its diameter size is from 0.1 to 0.5 micrometers, just bigger than flu virus, for example.
  4. Its sized characteristics allow them to participate in ions and molecules processes. This is a important fact, because this habilitates prokaryotes to move fast through all the cell, taking out undesired elements away.
  5. Prokaryotes are singled cells or unicellular this means that are simple cells.
  6. Its nucleoid contains a single chromosome.

*they lack an organized nucleus and other membrane bound organelles
*DNA is found in a "nucleoid" - a central part of the cell
*The cell wall is an extra layer of protection and maintains the cell's shape.

What is the average atomic mass of a sample that has two isotopes, one with a mass of 21 amu at 62% abundance and another with a
motikmotik

Answer:

Average atomic mass = 21.38 amu.

Explanation:

Given data:

Mass of first isotope = 21 amu

Abundance of first isotope = 62%

Mass of second isotope = 22 amu

Abundance of second isotope = 38%

Average atomic mass = ?

Solution:

Average atomic mass  = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (62×21)+(38×22) /100

Average atomic mass =  1302 +836 / 100

Average atomic mass = 2138 / 100

Average atomic mass = 21.38 amu.

Why do you think that individuals whose genotype is heterozygous for the recessive
Travka [436]

Answer:

An individual whose genotype is heterozygous cannot be for the recessive

Explanation:There are two possible genotypes either homozygous dominant or heterozygous dominant. For a charecter there can be two gene .One is recessive and other one is dominant. In presence of the dominant gene the recessive gene of the same character cannot express . IF recessive gene is homozygous then only it will express .Therefore for the individual it is heterozygous for the dominant

Which statements are true about variations in the genetic code?
Murrr4er [49]

Answer:

<u>C) They may provide selective advantages. </u>

<u>D) Slight differences in the genetic code may have significant results.</u>

Explanation:

The genetic code is universal, and present in most living beings . Generally, in most living organisms, the same codons are assigned to the same amino acids.  

DNA sequences make up genes that may have multiple variants, called alleles. DNA deoxyribonucleic acid, is transcribed into mRNA and then translated into amino acids that form proteins.

Natural selection mainly acts on phenotypes, which are dependent on proteins and the organisms's environment.  Phenotypes conferring advantageous traits are favored by the selection process- these help groups of organisms evolve over time.

Shana is a competitive athlete who weighs 135 lb. she would like to plan a nutritionally adequate diet that provides enough carb
sashaice [31]

Carbohydrates are your body’s main source of energy. The amount of carbs a man should consume daily depends on his age and activity level. The Institute of Medicine suggests adults to eat at least 130 grams of carbs a day. But If you’re a competitive athlete like Shana, you need additional amount.

<span>A study made by The Academy of Nutrition and Dietetics recommends a 2.3 to 4.5 grams of carbohydrates per pound of body weight each day, to athletes depending on the intensity of training. Therefore,  Shana who weighs 135 lbs, needs approximately  310.5 grams carbohydrates daily for her physical workouts. </span>
